ABSTRACT

ABSTRACT Objective: To evaluate the effect of pain and swelling related to third molars on patients' quality of life prior to third molar surgery. Material and Methods: The effects on quality of life with reference to oral health of 246 healthy patients seeking treatment of third molars were analyzed using the 14-item Oral Health Impact Profile (OHIP) questionnaire before surgery. The patients' sociodemographic characteristics, medical and dental history, reasons for third molar removal were recorded. Adverse effects of pain and swelling on oral health-related quality of life were recorded. Results: The mean age of the patients included in the study was 23.15 years, with maximum male patients and the mean OHIP-14 score of 8.01 ± 7.51. About 36.97% of patients reported that their chief complaint was pain/swelling due to third molar infection, and 27.9% of subjects reported one or more of the 14 OHIP items. The odds of reporting for age with ≥25 years was approximately 2 times greater than age with ≤25 years (OR=1.56, 95% CI: 1.01-2.57) and tooth loss due to traumatic history (OR=3.14, 95% CI: 2.12-6.54). Conclusion: Adverse influences on quality of life were seen in a significant number of patients seeking third molar removal. The probabilities increased by 3-fold for patients who had experienced pain or swelling than asymptomatic individuals.

ABSTRACT

Abstract Third molar removal surgery usually comes accompanied by postoperative discomfort, which could be influenced by the surgical approach chosen. This scoping systematic review aimed at compiling the available evidence focused on the influence of flap design, including envelope flap (EF), triangular flap (TF), and modified triangular flap (MTF), on postoperative pain, swelling, and trismus, as primary outcome measures, and any result mentioning healing promotion or delay, as secondary outcome measure, after mandibular third molar extraction surgery. An electronic search, complemented by a manual search, of articles published from 1999 to 2020 was conducted in the Medline (PubMed), EMBASE and Web of Science databases including human randomized controlled trials, prospective, and retrospective studies with at least 15 patients. The risk of bias of the included studies was assessed either with the Cochrane's Risk of Bias tool or with the Newcastle-Ottawa scale. Every step of the review was performed independently and in duplicate. The initial electronic search recovered 2102 articles. After applying the inclusion criteria, 12 articles were included. For patient's perceived postoperative pain, TF and MTF frequently reported better results than EF. For swelling, the literature is divided, despite a trend favoring EF. For trismus, data showed that its occurrence is mostly associated with the duration of the surgery rather than with the chosen flap. For healing, the limited data is inconclusive. Finally, randomized studies showed a high risk of bias, whereas nonrandomized studies were mostly of good quality and low risk of bias. Although there was no clear consensus regarding the influence of different flap designs for third mandibular molar extraction on postoperative clinical morbidities; the surgeon's experience, estimated surgical difficulty, molar position and orientation, and surg ery duration should be considered when choosing among the different flap designs.

ABSTRACT

Abstract: The aim of this study was to evaluate patient perception of surgical discomfort in third molar surgery and the association with clinical variables and polymorphisms associated with the FKBP5, SLC6A4, and COMT genes. This cross-sectional observational study was carried out on 196 participants aged between 18 and 64 years at the Federal University of Paraná in 11 months. The intensity of surgical discomfort was assessed using the QCirDental questionnaire. Data on surgical and individual procedures were also cataloged. The oral health related quality of life was assessed by the Oral Health Impact Profile questionnaire (OHIP-14). The DNA sample was obtained from cells of the oral mucosa. Five markers of the FKBP5, SLC6A4, and COMT genes were genotyped. The data were submitted to statistical analysis with a significance level of 5%. Women reported greater intensity of discomfort associated with third molar surgery compared to men (p = 0.001). In the recessive model, the AA genotype of the rs3800373 marker was associated with greater surgical discomfort (p = 0.026). Therefore, women and individuals of the AA genotype for the rs3800373 marker in the FKBP5 gene reported greater surgical discomfort associated with third molar surgery.

ABSTRACT

This study aimed to systematically review the literature to assess the effect of preemptive intravenous ibuprofen on pain reduction after lower third molar surgery. Nine databases (PubMed, Scopus, LILACS, SciELO, Embase, Web of Science, Cochrane, Open Gray, and Open Thesis) were used as sources of research, including "grey literature." The protocol was registered in PROSPERO. Only randomized clinical trials evaluating the effects of preemptive intravenous ibuprofen on pain during and immediately after the extraction of lower third molars were included, without restrictions of year and language. Two reviewers independently performed the study selection, data extraction, and assessment of the risk of bias. The "Joanna Briggs Institute for Randomized Controlled Trials" tool was used to assess the risk of bias. Each study was categorized according to the percentage of positive responses to the questions corresponding to the assessment instrument. The results were measured narratively/descriptively. The initial search resulted in 3,257 records, of which only three studies (n=150 participants) met the eligibility criteria and were included in the qualitative analysis. All studies were published in 2019. The risk of bias ranged from low to moderate. Two studies found significant pain reduction within 48 h after the procedure. In conclusion, the use of preemptive intravenous ibuprofen for extracting third molars reduces pain and analgesic consumption after the surgical procedure.

ABSTRACT

OBJECTIVES@#This study aims to analyze the effectiveness of platelet-rich fibrin (PRF) in mandibular third molar extraction and provide suggestions for alleviating postoperative complications.@*METHODS@#Pubmed, EMBASE, Web of Science, and SinoMed were searched electronically on February 2020. Randomized controlled trials focusing on PRF usage in mandibular third molar extraction were included. Reviewers assessed the risk of bias in the included literature and extracted data independently using the criteria recommended by the Cochrane Collaboration. Meta-analysis was performed using RevMan 5.3 and STATA 13.0.@*RESULTS@#Twenty-one studies were included, comprising 991 patients who had mandibular third molar extraction. The topical application of PRF effectively reduced pain after extraction [MD=-12.06, 95%CI (-21.42, -2.71), @*CONCLUSIONS@#Limited clinical evidence indicates that applying PRF after mandibular third molar extraction could reduce pain, swelling, trismus and the occurrence of dry socket and promote soft tissue healing. However, the effect of PRF on bone healing requires further large-scale randomized controlled trials and unified measurement criteria.

ABSTRACT

OBJECTIVES@#This prospective study was performed to evaluate whether the distal-triangular flap was a practical alternative surgical approach for extracting mandibular third molars.@*METHODS@#Sixty participants with impacted mandibular third molars were randomly divided into three groups: group A, distal-triangular flap; group B, Szmyd flap; and group C, envelope flap. The impacted third molars were extracted by the corresponding flapping method. During a three-month follow-up observation after the extraction, the postoperative pain, swelling, mouth opening, and periodontal status were recorded and analyzed by ANOVA and chi-square tests.@*RESULTS@#The 60 participants had successful extraction and 3-month follow-up observation. No participant suffered from postoperative infections, lower lip disorder, or tongue sensory disorders. No statistical differences were found in the postoperative symptoms and signs of the three flap designs, such as postoperative pain, swelling, mouth opening, and periodontal status (@*CONCLUSIONS@#The distal-triangular flap was as safe and reliable as the Szmyd and envelope flaps but more advantageous because of its convenient operative field exposure and low requirement for the patient's mouth opening. Thus, the distal-triangular flap is one of the alternative flap options for extracting impacted mandibular third molars.

ABSTRACT

Considering the adverse effects of nonimpacted third molars (N-M3s) on the periodontal health of adjacent second molars (M2s), the removal of N-M3s may be beneficial to the periodontal health of their neighbors. This study aimed to investigate the clinical, immunological, and microbiological changes of the periodontal condition around M2s following removal of neighboring N-M3s across a 6-month period. Subjects with at least one quadrant containing an intact first molar (M1), M2, and N-M3 were screened and those who met the inclusion criteria and decided to receive N-M3 extraction were recruited in the following investigation. M2 periodontal condition was interrogated before M3 extraction (baseline) and at 3 and 6 months postoperatively. Improvements in clinical periodontal indexes of M2s in response to their adjacent N-M3 removal, along with changes in inflammatory biomarkers among gingival crevicular fluid (GCF) and the composition of subgingival plaque collected from the distal sites of the M2s of the targeted quadrant were parallelly analyzed. Complete data of 26 tooth extraction patients across the follow-up period were successfully obtained and subsequently applied for statistical analysis. Compared to the baseline, the periodontal condition of M2s was significantly changed 6 months after N-M3 removal; specifically, the probing depth of M2s significantly reduced (P < 0.001), the matrix metalloproteinase (MMP)-8 concentration involved in GCF significantly decreased (P = 0.025), and the abundance of the pathogenic genera unidentified Prevotellaceae and Streptococcus significantly decreased (P < 0.001 and P = 0.009, respectively). We concluded that N-M3 removal was associated with superior clinical indexes, decreased GCF inflammatory biomarkers, and reduced pathogenic microbiome distribution within the subgingival plaque. Although the retention or removal of N-M3s continues to be controversial, our findings provide additional evidence that medical decisions should be made as early as possible or at least before the neighboring teeth are irretrievably damaged.

ABSTRACT

Introdução: A Coronectomia é um tratamento alternativo à remoção total do terceiro molar inferior impactado/incluso, removendo apenas a região coronária do dente, preservando suas raízes. O objetivo desta pesquisa é mensurar o nível de conhecimento e percepção dos Cirurgiões e Residentes Buco-Maxilo-Faciais, em três hospitais da rede pública da cidade do Recife, Pernambuco, sobre a técnica da Coronectomia. Metodologia: A amostra foi composta por 40 profissionais, dentre os quais 50% de todos os entrevistados declararam não realizar a técnica da Coronectomia na remoção de terceiros molares. Foi realizado o Teste Exato de Fisher que não apontou dependência entre as categorias de participante da entrevista quanto ao grau de conhecimento sobre a técnica de Coronectomia. Resultados: Os entrevistados conhecem a técnica de Coronectomia, mas a sua indicação não é frequente e as contraindicações mais citadas foram lesões neoplásicas e terceiros molares com patologia apical. Consideram muito importantes e importantes as vantagens do procedimento em relação à remoção total dos terceiros molares. 70% dos entrevistados veem a necessidade de reintervenção como a maior desvantagem na técnica, porém, estudos dizem que raramente ocorrem erupções dessas raízes. Conclusão: A técnica da Coronectomia é eficaz quando corretamente indicada e realizada, pois, reduz o risco de uma lesão ao nervo alveolar inferior... (AU)


Introduction: Coronectomy is an alternative treatment to the total removal of the impacted / included lower third molar, removing only the coronary region of the tooth, preserving its roots. The objective of this research is to measure the level of knowledge and perception of Surgeons and Buco-Maxillofacial Residents, in three public hospitals in the city of Recife, Pernambuco, on the technique of Coronectomy. Methodology: The sample consisted of 40 professionals, among whom 50% of all respondents stated that they did not perform the Coronectomy technique in the removal of third molars. Fisher's Exact Test was performed, which did not show any dependence between the interviewee categories regarding the degree of knowledge about the Coronectomy technique. Results: The interviewees are familiar with the Coronectomy technique, but its indication is not frequent and the most frequently mentioned contraindications were neoplastic lesions and third molars with apical pathology. The advantages of the procedure in relation to the total removal of third molars are considered very important and important. 70% of respondents see the need for reintervention as the biggest disadvantage in the technique; however, studies say that eruptions of these roots rarely occur. Conclusion: The Coronectomy technique is effective when correctly indicated and performed, as it reduces the risk of injury to the lower alveolar nerve... (AU)

ABSTRACT

Introducción: La profilaxis antibiótica es controvertida, además que su uso inapropiado expone a los pacientes en riesgo de reacciones adversas y desarrollo de resistencia bacteriana. Objetivo: Realizar una revisión sistemática de ensayos clínicos aleatorizados que evaluaron le eficacia de la profilaxis antibiótica en la reducción de infecciones posoperatorias luego de la extracción de terceros molares impactados. Métodos: Fueron utilizadas las bases de datos ScienceDirect, Clinical trials.gov y Scopus para ubicar ensayos clínicos. Las variables primarias incluyeron: presencia de infecciones posoperatorias (de la herida y/o alveolitis), reacciones adversas, trismo y dolor. Se realizó un metaanálisis con los estudios homogéneos a través del análisis de efectos aleatorios. El riesgo de sesgo de los ensayos incluidos fue evaluado a través de la guía Cochrane. El riesgo relativo global fue calculado utilizando el enfoque del inverso de la varianza con el método de efectos aleatorios. Resultados: Fueron analizados cualitativamente 14 ensayos clínicos y 9 cuantitativamente. De un total de 874 pacientes, 49 (5,6 por ciento) presentaron infecciones posoperatorias (16/446 para el grupo experimental y 33/428 para el grupo placebo). El metaanálisis arrojó un riesgo relativo global de 0,5 (IC 95 por ciento: 0,27-0,94). El riesgo de sesgo para los estudios que utilizaron solo amoxicilina como medida profiláctica fue de 0,53 (IC 95 por ciento: 0,27-1,03). Las principales reacciones adversas incluyeron: diarreas, reacciones gastrointestinales, fiebre y dolor gástrico. Conclusiones: Los antibióticos sistémicos administrados antes de la cirugía fueron eficaces para reducir las frecuencias de aparición de infecciones posoperatorias luego de la extracción de terceros molares impactados(AU)


Introduction: Antibiotic prophylaxis is controversial, and its inappropriate use exposes patients to the risk of adverse reactions and the development of bacterial resistance. Objective: Carry out a systematic review of randomized clinical trials evaluating the efficacy of antibiotic prophylaxis for the reduction of postoperative infections after extraction of impacted third molars. Methods: The search for clinical trials was conducted in the databases ScienceDirect, Clinicaltrials.gov and Scopus. The primary variables considered were presence of postoperative infections (of the wound and/or alveolitis), adverse reactions, trismus and pain. A meta-analysis was made of homogeneous studies applying the random effects model. The risk of bias in the trials included was evaluated using the Cochrane guide. The inverse variance approach and the random effects method were used for estimation of the global relative risk. Results: Fourteen clinical trials were analyzed qualitatively and 9 quantitatively. Of the total 874 patients, 49 (5.6 percent:) developed postoperative infections (16 / 446 for the experimental group and 33 / 428 for the placebo group). The meta-analysis found a global relative risk of 0,5 (CI 95 percent: 0,27-0,94). Bias risk for studies using only amoxicillin as a prophylactic measure was 0,53 (CI 95 percent:: 0,27-1,03). The main adverse reactions were diarrhea, gastrointestinal reactions, fever and abdominal pain. Conclusions: The systemic antibiotics administered before the surgery were effective to reduce the frequency of appearance of postoperative infections after extraction of impacted third molars(AU)

ABSTRACT

Objective: This review addresses a clinical research question related to lower third molar surgery (L3MS): does the combination of pre-emptive low-dose ketamine with local anesthesia (KLA) reduce postoperative complications compared with local anesthesia (LA) alone? Material and methods: A systematic literature search was performed to identify eligible articles by electronic searches of PubMed, Cochrane Central Register of Controlled Trials, EBSCO Library, Web of Science and grey literature through June 2019 without data or language restrictions. We analyzed all randomized controlled clinical studies (RCTs) comparing use of KLA with use of LA in L3MS regarding pain, swelling, and trismus outcomes. The quality of evidence was rated according to Cochrane's tool for assessing risk of bias. Results: Five RCTs encompassing 230 extraction sites (KLA = 115, LA = 115) were included in this study. The standardized mean difference (SMD) with the 95% confidence interval (CI) was used to synthesize the results. The data show that there were significant differences between the two groups in post-operative pain (SMD -1.464, 95% CI -1.683 to -0.949, p= 0.001) and swelling (SMD -0.450, 95% CI -0.758 to -0.142, p= 0.004, all low quality evidence). However, there was no significant difference in the trismus (SMD -0.754, CI -1.487 to -0.022, p = 0.043, very low quality evidence). Conclusion: The combination of pre-emptive low-dose ketamine with LA significantly decreased pain and swelling within the first 24 hours after L3MS compared with the control group.


Objetivo: Esta revisión aborda una pregunta de investigación clínica relacionada con la cirugía del tercer molar inferior (L3MS): ¿la combinación de ketamina preventiva en dosis bajas con anestesia local (KLA) reduce las complicaciones postoperatorias en comparación con la anestesia local (AL) sola? Material y Métodos: Se realizó una búsqueda bibliográfica sistemática para identificar artículos elegibles mediante búsquedas electrónicas en PubMed, Registro Cochrane Central de Ensayos Controlados, Biblioteca EBSCO, Web of Science y literatura gris hasta junio de 2019 sin restricciones de datos ni de idioma. Se analizaron todos los estudios clínicos controlados aleatorios (ECA) que compararon el uso de KLA con el uso de LA en L3MS con respecto a los resultados de dolor, hinchazón y trismo. La calidad de la evidencia se clasificó de acuerdo con la herramienta Cochrane para evaluar el riesgo de sesgo. Resultados: Se incluyeron en este estudio cinco ECA que abarcan 230 sitios de extracción (KLA = 115, LA = 115). La diferencia de medias estandarizada (DME) con el intervalo de confianza (IC) del 95% se utilizó para sintetizar los resultados. Los datos muestran que hubo diferencias significativas entre los dos grupos en el dolor posoperatorio (DME -1,464; IC del 95%: -1,683 a -0,949; p= 0,001) e hinchazón (DME -0,450; IC del 95%: -0,758 a -0,142, p= 0,004, todas las pruebas de baja calidad). Sin embargo, no hubo diferencias significativas en el trismo (DME -0,754; IC: -1,487 a -0,022; p= 0,043, evidencia de muy baja calidad). Conclusión: La combinación de ketamina preventiva en dosis bajas con LA disminuyó significativamente el dolor y la hinchazón dentro de las primeras 24 horas después de la L3MS en comparación con el grupo de control.

ABSTRACT

Dentes impactados são caracterizados pela falha na erupção dentro do tempo cronológico. O termo ''dente invertido'' se refere ao mau posicionamento do dente, caracterizando-se pelo dente na direção contrária à usual. A inversão de dente impactado é considerada um fenômeno raro. Em casos mais complexos de impacção dentária, há a necessidade de um tratamento conservador, específico e procura-se prevenir possíveis danos às estruturas anatômicas adjacentes. Por essa razão, a técnica cirúrgica denominada coronectomia, também conhecida como odontectomia parcial intencional, tem, em alguns casos, indicação de uso, pois realiza-se a exérese da porção coronária do dente, sepultando as suas raízes, quando estas se encontram em contato com estruturas nobres. Dessa forma, este trabalho tem como objetivo apresentar um caso raro da utilização da técnica de coronectomia para um terceiro molar superior invertido em paciente do sexo feminino, 26 anos, que compareceu ao serviço de Cirurgia Buco-Maxilo-Facial apresentando um terceiro molar superior, assintomático, impactado em posição invertida no lado esquerdo. Ao exame tomográfico, apresentou íntimo contato do dente 28 com as raízes do 27. A porção coronária se encontrava em posição superior, em direção a parte posterior do seio maxilar. A técnica da coronectomia foi escolhida como planejamento cirúrgico, a fim de proteger o dente 27 das possíveis consequências traumáticas que a luxação e extração completa do dente 28 poderia ocasionar. O acompanhamento clínico demonstrou que a técnica foi bem indicada, com evolução de neoformação óssea completa na região da coroa removida e o dente adjacente com vitalidade e em função mastigatória(AU)


Impacted teeth are characterized by eruption failure within chronological time. The term 'inverted tooth' refers to the mispositioning of the tooth, characterized by the tooth in the opposite direction to the usual one. Impacted tooth inversion is considered a rare phenomenon. In more complex cases of dental impaction, there is a need for conservative and specific treatment, and attempts are made to prevent possible damage to adjacent anatomical structures. For this reason, the surgical technique called coronectomy, also known as intentional partial odontectomy, has, in some cases, indication of use, where the coronary portion of the tooth is excised, burying its roots when they are in contact with noble structures. Thus, this paper aims to present a rare case of the use of the inverted upper third molar coronectomy technique in a 26-year-old female patient, who attended the Buccomaxillofacial Surgery Service presenting a superior third molar, asymptomatic, impacted in inverted position on the left side. At tomographic examination, the patient presented close contact of tooth #16 with the roots of tooth #15. The coronary portion was in the superior position, towards the posterior part of the maxillary sinus. The coronectomy technique has been chosen as a surgical planning in order to protect tooth #15 from the possible traumatic consequences that dislocation and complete extraction of tooth #16 could cause. Clinical follow-up showed that the technique was successfully indicated, with complete bone neoformation in the removed crown area and the adjacent tooth with vitality and masticatory function(AU)

ABSTRACT

ABSTRACT Objective: To evaluate the skill of orthodontists and oral/maxillofacial surgeons (OMFS) in providing a prognosis of mandibular third molars spontaneously erupted, through follow-up panoramic analysis. Methods: 22 orthodontic patients treated without extraction, presenting spontaneously erupted mandibular third molars (n = 44) were analyzed through panoramic serial radiographs. The first panoramic radiograph was obtained just after orthodontic treatment (PR1), in patients aging from 13 to 19 years. A second panoramic radiograph (PR2), was obtained in average two years later. The radiographs were randomly analyzed by 54 specialists, 27 orthodontists and 27 OMFS, to obtain the opinion about the approach to be adopted to these teeth in PR1. Then, another opinion was collected by adding a serial radiograph (PR1+2). Results: The concordance of the answers was moderate for OMFS (Kappa 0.44; p< 0.0001) and significant for orthodontists (Kappa 0.39; p< 0.0001). In the analysis of the first radiograph (PR1) of the spontaneously erupted molars, OMFS indicated extraction in 44.5% of cases, while orthodontists indicated in 42%, with no difference between groups (p= 0.22). In PR1+2 analysis, orthodontists maintained the same level of extraction indication (45.6%, p= 0.08), while surgeons indicated more extractions (63.2%, p< 0.0001). Conclusions: Orthodontists and OMFS were not able to predict the eruption of the third molars that have erupted spontaneously. Both indicated extractions around half of the third molars. A follow-up analysis, including one more radiograph, did not improve the accuracy of prognosis among orthodontists and worsened for OMFS.


RESUMO Objetivo: Avaliar a habilidade de ortodontistas e cirurgiões bucomaxilofaciais (CBMF) em propor um prognóstico para terceiros molares inferiores. Métodos: Foram analisados 22 pacientes tratados ortodonticamente sem extração, cujos terceiros molares inferiores irrompidos espontaneamente (n= 44) foram avaliados por meio de radiografias panorâmicas seriadas. A primeira radiografia foi obtida logo após o tratamento ortodôntico (RX1), entre 13 e 19 anos de idade. A segunda radiografia (RX2) foi avaliada dois anos depois, em média. As radiografias foram analisadas aleatoriamente por 54 especialistas, 27 ortodontistas e 27 CBMFs, para obter sua opinião sobre a abordagem a ser adotada na RX1. Em seguida, outra opinião foi coletada adicionando-se a segunda radiografia seriada (RX1+2). Resultados: A concordância das respostas foi moderada para os CBMFs (Kappa = 0,44; p< 0,0001) e significativa para os ortodontistas (Kappa = 0,39; p< 0,0001). Após analisar apenas a primeira radiografia (RX1) dos molares antes deles irromperem espontaneamente, os CBMFs indicaram extração em 44,5% dos casos; enquanto os ortodontistas, em 42%, sem diferença entre os grupos (p= 0,22). Na análise de RX1+2, os ortodontistas mantiveram o mesmo nível de indicação de extração (45,6%, p= 0,08), enquanto os cirurgiões passaram a indicar mais extrações (63,2%, p< 0,0001). Conclusões: Ortodontistas e CBMFs não foram capazes de predizer a erupção de terceiros molares por meio da análise de uma única radiografia panorâmica, indicando extrações em cerca da metade dos terceiros molares examinados. Uma análise de acompanhamento, incluindo mais uma radiografia, não melhorou a precisão do prognóstico entre os ortodontistas, e piorou entre os CBMFs.

ABSTRACT

INTRODUCCIÓN: La coronectomía se considera una alternativa a la extracción total en los casos donde las raíces de los terceros molares inferiores están en íntimo contacto con el nervio alveolar inferior. Existe incertidumbre sobre si la coronectomía disminuye la incidencia de parestesia en comparación a la extracción total. MÉTODOS: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un meta análisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos seis revisiones sistemáticas que en conjunto incluyeron 17 estudios primarios, de los cuales, dos corresponden a ensayos clínicos aleatorizados. Concluímos que la coronectomía en comparación a la extracción total de los terceros molares inferiores probablemente se asocia a un menor riesgo de parestesia. Además, no está claro si la coronectomía en comparación a la extracción total de terceros molares inferiores podría aumentar el riesgo de infección (certeza de la evidencia es muy baja).

ABSTRACT

Third molars usually erupt within the age of 17 ­ 21years. Usually, due to the evolution of human jaws, the size is decreasing leading to the impacted tooth. An impacted tooth may lead to external resorption of the adjacent tooth, trismus, infection, etc. Many studies have been reported in the literature for evaluating the surgical difficulty and postoperative complications secondary to impacted third molars. This study includes a sample of 100 subjects evaluated for the surgical difficulty and postoperative complications. Various demographic, radiological, and intraoperative factors were evaluated which may lead to postoperative complications. Factors responsible for postoperative sequelae were also evaluated with complications. Postoperative pain after 4 hours and 7 days was assessed to mark the factors commonly responsible. Pain at 7th postoperative day was significant involving factors like fully impacted, horizontal impaction, level C, no/very little retromolar space, and root contact. Postoperative complications were not reported in this study.


Los terceros molares suelen erupcionar entre los 17 y los 21 años de edad. Por lo general, debido a la evolución de las mandíbulas humanas, el tamaño disminuye, lo que conduce al diente impactado. Un diente impactado puede conducir a la reabsorción externa del diente adyacente, trismo, infección, etc. Se han reportado muchos estudios en la literatura para evaluar la dificultad quirúrgica y las complicaciones postoperatorias secundarias a terceros molares impactados. Este estudio incluye una muestra de 100 sujetos evaluados por la dificultad quirúrgica y las complicaciones postoperatorias. Se evaluaron diversos factores demográficos, radiológicos e intraoperatorios que pueden conducir a complicaciones postoperatorias. También se evaluaron los factores responsables de las secuelas postoperatorias con las complicaciones. Se evaluó el dolor postoperatorio después de 4 horas y 7 días para marcar los factores comúnmente responsables. El dolor al séptimo día postoperatorio fue significativo e involucró factores como impacto total, impactación horizontal, nivel C, espacio retromolar nulo o muy pequeño y contacto con la raíz. En este estudio no se informaron complicaciones posoperatorias.

ABSTRACT

ABSTRACT: Anxiety in dental surgery may lead to behavioral and physiological changes for the patient and constitute a frequent challenge for the oral surgeon. The objective of this study was to compare the effect of inhalatory nitrous oxide and oxygen (N2O/O2) with oral diazepam conscious sedation in vital signs of patients undergone third molar extraction. Outpatients who needed removal of partially impacted, bilateral lower third molars, during the period of one year, were included. Each patient underwent conscious sedation with either oral diazepam or inhalatory N2O/O2 on a randomized controlled trial, split-mouth design. Systolic and diastolic blood pressure, heart rate and oxygen blood saturation were the changes measured before, at the beginning and the end of the procedure. Also, surgical procedure duration was recorded. Data from vital signs were submitted to analysis of variance and the duration of the surgery to paired Student's t-test. Twenty-five healthy outpatients (13 women and 12 men) with a mean age of 21.6 years were studied. There was an increase in systolic and diastolic pressure and in heart rate in the beginning; these values decreased and stabilized at the end of the surgical procedure in both treatments (p < 0.001) being lower in N2O/O2 but without difference between treatments. The surgical procedure duration was lower and occurred an expected increase of oximetry under N2O/O2 sedation (p < 0.001). Both treatments were effective for the conscious sedation but N2O/O2 showed better outcomes, mainly in duration of the surgery.


RESUMEN: La ansiedad en la cirugía dentoalveolar puede conducir a alteraciones fisiológicas y de comportamiento en el paciente, constituyendo así un desafío frecuente para el cirujano maxilofacial. El objetivo de este estudio fue comparar el efecto del óxido nitroso inhalatorio con oxígeno (N2O/O2) y la sedación consciente oral con diazepam por médio de los signos vitales de pacientes sometidos a la extracción del tercer molar. Fueron incluídos pacientes ambulatoriales com necesidad de exodoncia de terceros molares inferiores bilaterales, parcialmente impactados, durante el período de un año. Cada paciente fue sometido a sedación consciente con diazepam oral o N2O/O2 por inhalación en un ensayo controlado aleatorio, diseño de boca dividida. La presión arterial sistólica y diastólica, la frecuencia cardíaca y la saturación de oxígeno en la sangre fueron medidos antes, al inicio y al final del procedimiento. Además, se registró la duración del procedimiento quirúrgico. Los datos de los signos vitales fueron enviados para análisis de varianza y la duración de la cirugía para la prueba t de Student pareada. Se estudiaron 25 pacientes ambulatorios sanos (13 mujeres y 12 hombres) con una edad media de 21,6 años. Al início hubo un aumento en la presión sistólica y diastólica y en la frecuencia cardíaca; estos valores disminuyeron y se estabilizaron al final del procedimiento quirúrgico en ambos tratamientos (p <0,001), siendo más bajos en N2O/ O2 pero sin diferencia entre los tratamientos. La duración del procedimiento quirúrgico fue menor y se produjo un aumento esperado de la oximetría bajo sedación con N2O/O2 (p <0,001). Ambos tratamientos fueron efectivos para la sedación consciente, pero el N2O/O2 mostró mejores resultados, principalmente en la duración de la cirugía.

ABSTRACT

Abstract Objective: To assess the patterns of mandibular third molar impaction in an Iranian subpopulation. Material and Methods: This retrospective descriptive study evaluated 1000 panoramic radiographs retrieved from the archives of a private radiology clinic in Kermanshah city, Iran. Depth of impaction, position of impacted mandibular third molar relative to the mandibular ramus according to Pell and Gregory's classification and angle of impacted tooth according to Winter's classification were determined. Data were analyzed using the Chi-square and Wilcoxon tests. Results: Of 1000 radiographs, 230 (23%) showed an impaction of at least one mandibular third molar. Mandibular third molar impaction was more common in females (60%). Mesioangular (35.9%) and vertical (34.8%) impactions were the most common angles of impaction in the right and left sides, respectively. Level C (40.3%) and Class I (63.7%) were the most common types of impaction in terms of depth of impaction and position relative to ramus, respectively. No significant difference was observed between the right and left sides of the mandible in terms of patterns of mandibular third molar impaction (p>0.05). Conclusion: Mandibular third molar impaction was relatively common in the studied population. The mesioangular, level C and Class I impaction patterns were the most frequent.

ABSTRACT

Objective: To compare the anti-inflammatory effectiveness of dexa-methasone as pre-surgical and post-surgical therapy in mandibular third molar surgery. Materials and methods: Randomized clinical trial conducted in 60 patients in need of mandibular third molar extraction, ages ranging from 16 to 35 years old, at the Department of Oral and Maxillofacial Surgery of the Arzobispo Loayza National Hospital during the period of January-March, 2016. Patients were distributed in two randomized groups: Group A received 4mg dexamethasone intramuscular before the surgery, and Group B received the same medication post-surgery. Facial edema was assessed using the distance between facial points, trismus was evaluated using the interincisal distance, and pain intensity was determined using a Numerical Scale (NS). Results: Facial edema values were lower in Group A at 60 minutes (p=0.002) and after the first (p=0.001) and third days (p=0.009), compared to Group B. Regarding trismus, no significant differences between the groups were found. Regarding pain intensity, the highest point was recorded at 6 hours in both groups; however, no significant differences between the groups were found. Conclusion: Pre-surgical dexamethasone administration produced a significantly greater reduction in facial edema after mandibular third molar surgery.


Objetivo: Comparar la efectividad antiinflamatoria de dexametasona como terapia prequirúrgica y postquirúrgica en la cirugía del tercer molar mandibular. Materiales y métodos: Ensayo clínico aleatorizado que incluyó a 60 pacientes de 16 a 35 años del Servicio de Cirugía Bucal y Maxilofacial del Hospital Nacional Arzobispo Loayza con necesidad de exodoncia de tercer molar mandibular durante el periodo de enero a marzo del 2016. Se distribuyeron en dos grupos aleatoriamente: El grupo A recibió prequirúrgicamente 4 mg de dexametasona vía intramuscular y el grupo B recibió la misma medicación postquirúrgicamente. Se evaluó el edema facial, mediante la distancia entre puntos faciales, el trismus mediante la distancia interincisal y la intensidad de dolor mediante la Escala Numérica (EN). Resultados: Los valores del edema facial fueron menores en el grupo A a los 60 minutos (p=0,002), primer (p=0,001) y tercer día (p=0,009) en comparación al grupo B. Respecto al trismus, no se encontró diferencia significativa entre los grupos durante las evaluaciones realizadas. Respecto al dolor, la mayor intensidad se percibió a las 6 horas en ambos grupos; sin embargo, no se encontró diferencia significativa entre los grupos durante todas las evaluaciones realizadas. Conclusión: La administración prequirúrgica de dexametasona produjo una significativa mayor reducción del edema facial posterior a la cirugía del tercer molar mandibular.

ABSTRACT

Introducción: La odontectomía del tercer molar produce una respuesta metabólica al trauma quirúrgico caracterizada por una importante infl amación del área, por lo que para su control se cuenta con diferentes opciones terapéuticas como la farmacoterapia, crioterapia y laserterapia, así como otras alternativas como la compresión de la región, cuya propuesta presentada en este trabajo es a través de la utilización de un apósito adhesivo facial. Objetivo: Evaluar la efi cacia de la aplicación de un apósito adhesivo facial para el control de la infl amación postquirúrgica de la odontectomía del tercer molar. Material y métodos: Se realizó un ensayo clínico controlado de fase I multicéntrico. Se conformó un grupo de estudio experimental y de control con 10 participantes en cada uno, de ambos sexos, de 18-30 años de edad, sanos y que presentaron un tercer molar inferior izquierdo retenido vertical o mesioangular, clase I o II, posición A o B (Pell y Gregory). Se efectuaron las odontectomías bajo anestesia local y sólo en el grupo experimental se utilizó un apósito adhesivo transparente marca Tegaderm® de 3M, el cual se colocó sobre la mejilla de los pacientes durante 48 horas. La evaluación de la infl amación se realizó con el método de Laskin modifi cado previo al procedimiento, a las 48 horas y en el quinto día postoperatorio. Resultados: El promedio de la longitud de la línea 1 a las 48 horas y al quinto día postoperatorio en el grupo experimental fue menor que en el grupo control siendo las diferencias estadísticamente signifi cativas. En el resto de las líneas, la longitud promedio también fue menor en el grupo experimental; sin embargo, no se encontraron diferencias estadísticamente signifi cativas. Conclusión: Este ensayo clínico no es concluyente respecto a la efi cacia del apósito adherible facial para reducir la infl amación postquirúrgica de la odontectomía del tercer molar (AU)


Introduction: The third molar odontectomy produces a metabolic response to surgical trauma characterized by an important infl ammation of the area, so that, for its control, it has diff erent therapeutic options as the pharmacotherapy, cryotherapy and laser therapy, as well as other alternatives such as compression of the region, whose proposal presented in this work is using a facial adhesive dressing. Objective: Evaluate the eff ectiveness of the implementation of a facial adhesive dressing for the control of postsurgical infl ammation of the third molar odontectomy. Material and methods: It has been made a controlled clinical trial of phase I multicentric. It formed a group of experimental and control study with 10 participants in each one, of both sexes, 18- 30 years of age, healthy and that presented a lower left third molar retained vertical or mesioangular, class I or II, position A or B (Pell and Gregory). Odontectomy were performed under local anesthesia and only in the experimental group used a transparent fi lm dressing Tegaderm® by 3M which was placed on the cheek of the patients for 48 hours. The evaluation of the infl ammation was performed with the method of Laskin modifi ed prior to the procedure, at 48 hours and on the 5th postoperative day. Results: The average of the length of the line 1 to 48 hours and at the 5th postoperative day was lower in the experimental group than in the control group, the diff erences being statistically signifi cant. In the rest of the lines, the average length was also lower in the experimental group, however, there were no statistically signifi cant diff erences. Conclusion: This trial is not conclusive as to the eff ectiveness of the dressing stick coating facial to reduce the postsurgical infl ammation of the third molar odontectomy (AU)
