Complicações odontológicas em indivíduos com insuficiência renal crônica: estudo retrospectivo / Dental complications in chronic renal failure individuals: a retrospective study

A doença renal crônica em estágio terminal pode levar a alterações sistêmicas que tornam o manejo clínico odontológico desses indivíduos desafiador, especialmente se os procedimentos forem invasivos. As preocupações incluem alteração do metabolismo de drogas, da resposta imunológica e do metabolismo ósseo, além do risco aumentado de sangramento e discussão sobre risco aumentado para endocardite infecciosa. O objetivo deste estudo retrospectivo foi conhecer a frequência e o tipo de complicações durante e após execução de procedimentos odontológicos em indivíduos com insuficiência renal crônica em diálise (IRC-D), atendidos no Centro de Atendimento a Pacientes Especiais (CAPE) da Faculdade de Odontologia da USP (FOUSP). Adicionalmente, comparamos a quantidade e o tipo de complicações entre os indivíduos que usaram antibiótico profilático e aqueles que não usaram, antes dos procedimentos odontológicos. Para tanto desenvolvemos um formulário específico para este estudo, no qual compilamos as informações relativas aos períodos trans e pós-operatórios de procedimentos odontológicos realizados nos pacientes com IRC em diálise. Nossa hipótese era a de que a prevalência de complicações durante e após os procedimentos odontológicos de indivíduos com IRC em diálise fosse baixa, e que ouso do antibiótico prescrito profilaticamente não interferiria na qualidade dareparação ou na incidência de complicações relacionadas aos procedimentos odontológicos. Analisamos retrospectivamente 225 prontuários de pacientes com IRC em diálise atendidos no CAPE-FOUSP desde 1990 até os dias atuais. Desse total, 130 eram pacientes do sexo masculino e do 95 do feminino. A idade média destes indivíduos foi de 48,4 anos. As principais doenças de base que levaram a ocorrência da IRC-HD foram a hipertensão arterial sistêmica (48 pacientes) e o diabetes mellitus (23 pacientes). Nos 225 pacientes, 1.390 procedimentos odontológicos foram realizados, dos quais 856 foram não invasivos, 443 invasivos e 91 tratamentos endodônticos. Dentre os procedimentos invasivos, houve 259 exodontias. Antes de 80 das 259 intervenções cirúrgicas (31%) houve a prescrição de antibiótico profilático em diferentes posologias; em 29 exodontias (11%) foram utilizados hemostáticos locais no momento da realização da sutura. Foram descritos nos prontuários 16 casos de sangramento transoperatório (6%), 5 casos de sangramento pós-operatório (2%) e 2 casos de complicação pós-operatória (0,8%), definidos como uma alveolite e uma infecção alveolar. Nossos resultados permitiram nos concluir que a incidência de complicações após exodontias é baixa e que o uso de antibiótico profilático (AP) não interferiu nessa incidência.

Al comparar ambos grupos en la curación de los tejidos blandos de alveolos post exodoncia atraumática se encontró que existe una diferencia estadísticamente significativa a los 7 y 14 días después de la cirugía (p0.05). La FRP presenta un efecto positivo en la curación de los tejidos blandos de alveolos post exodoncia atraumática de forma independiente del sexo y la edad.

The objective of the study was to determine the effect of platelet-rich fibrin (PRF) on the healing of soft tissues of socket after atraumatic exodontia. The present is a single-blind, cross-sectional randomized controlled trial. It was carried out in the Dental Service of the Santa Isabel District Hospital of Porvenir - Peru, during the years 2016 and 2017. The sample consisted of 51 patients whose alveoli post exodontia were randomly divided into 2 groups, each patient signed an informed consent. Group A (control) was left with a blood clot for normal healing and group B (experi- mental) was given PRF (as a plug and membrane), obtained according to the Choukroun protocol. The effect of PRF on the healing of the soft tissues of the alveoli after atraumatic exodontia was used the Landry index. The measurements were made at 7 and 14 days after surgery. For the comparison of each one of the variables of the study, the Mc Nemar test and the Fisher exact test were used. The statistical significance was 5 %. When comparing both groups in the healing of the soft tissues of alveoli after atraumatic exodontia, a statistically significant difference was found at 7 and 14 days after surgery (p 0.05). The PRF has a positive effect on the healing of the soft tissues of the alveoli after atraumatic exodontia independently of sex and age.

La complicación mayormente observada fue la alveolitis alcanzando un 2,5% de las cirugías de terceros molares y un 3,7% de las exodoncias de otros dientes. Las hemorragias postoperatorias se observaron en un 1,1% de las cirugías de terceros molares. Otras complicaciones postquirúrgicas fueron abscesos de espacios faciales, parestesia del nervio alveolar inferior, hematomas, equimosis y periostitis. CONCLUSIÓN: Los resultados fueron similares a los reportados en la literatura tanto en su frecuencia como en el tipo de complicación.

OBJECTIVE: The main objective of this investigation was to determine the incidence of postoperative complications in oral surgery. MATERIALS AND METHODS: An observational and descriptive study was developed with the use of the prospective registry of the patients admitted for oral surgery in the San Borja Arriarán Hospital Complex for a twelve-month period of observation (April 2017 to March 2018). RESULTS: The sample consisted of 532 patients undergoing surgical procedures of oral surgery and 29 cases of postoperative complications. The incidence of complications reached 5,5% and it was observed predominantly in interventions of tooth extraction. The most commonly observed complication was dry socket, reaching 2,5% of third molar surgeries and 3,7% of extractions of other teeth. Postoperative hemorrhages were observed in 1,1% of third molar surgeries. Other postoperative complications were facial spaces abscesses, paresthesia of the inferior alveolar nerve, bruising, ecchymosis and periostitis. CONCLUSIONS: The results were similar to those reported in the literature both in their frequency and in the type of complication.

Is treatment with platelet-rich fibrin better than zinc oxide eugenol in cases of established dry socket for controlling pain, reducing inflammation, and improving wound healing?

OBJECTIVES: To appraise the effectiveness of platelet-rich fibrin (PRF) in the management of established dry socket in terms of pain, inflammation, and wound healing. MATERIALS AND METHODS: Two hundred patients with established alveolar osteitis were studied to determine the efficacy of PRF and zinc oxide eugenol (ZOE) for pain control, inflammation reduction, and wound healing. Patients were randomly allocated to Group A (PRF) or Group B (ZOE). Patients were examined on the 1st, 3rd, 7th, and 14th postoperative day and evaluated for pain using visual analogue scale scores, inflammation with a gingival index score, and wound healing through a determination of the number of bony walls exposed. RESULTS: Group A showed better results in terms of pain remission, control of inflammation, and wound healing compared to Group B. Results between groups were statistically significant (P<0.05). CONCLUSION: PRF is a better alternative than ZOE for the effective management of alveolar osteitis.

Post-extraction pain in the adjacent tooth after surgical extraction of the mandibular third molar

BACKGROUND: After tooth extraction, pain due to dry socket and pain in the adjacent tooth are common. The aim of this study was to retrospectively analyze pain in the adjacent tooth after surgical extraction of the mandibular third molar. METHODS: Postoperative pain due to dry socket, pain in the adjacent tooth, and pain from other causes were present. Group A included patents with dry socket alone; group B included patients with pain in the adjacent tooth alone; and group C included patients with both. The duration of symptoms was recorded. In addition, the prognosis of pain was divided into the complete improvement, improvement, maintenance, deterioration, and complete deterioration groups. RESULTS: A total of 312 mandibular third molars were extracted from 13, 60, and 10 patients in groups A, B, and C, respectively. The mean duration of symptoms was 5 days in group A and B and 15.2 days in group C. There were statistically significant differences in the duration of symptoms between groups A and C and groups B and C. CONCLUSION: Pain in the adjacent tooth after third molar extraction can be caused by inflammatory reactions and pressure on this tooth. The pain caused by pressure on the periodontal ligament and alveolar bone results from the cytokines released by osteoclasts, which are responsible for bone destruction. However, pain from periodontal ligament damage caused by excessive pressure may be misunderstood as pulpal pain. Unconscious parafunctional habits, such as clenching and bruxism, could also be associated with post-extraction pain.

Introduction: Traumatic ulcers are characterized by short and painful episodes, but can become chronic if the causative agent is not removed. Alveolisis is an alteration that may occur during the primary tooth root resorption process, characterized by its exposure to the oral cavity, without resorption. Objective: To describe the case of a patient with an important edema and associated pain in the upper lip due to traumatic ulcer caused by exposure of the root apex of a primary incisor. Case presentation: Female patient aged 5 years old. After clinical examination, it was deduced that the lip swelling was related to the ulcer that was caused by the constant contact with the apex of the central incisor that has undergone alveolisis. The treatment consisted in the extraction of the tooth and the preservation of the labial mucosa ulcer. The extraction favored the eruption of the permanent incisor, allowed the complete healing of the traumatic lesion and the remission of the upper lip edema. Conclusions: Although simple, the case highlights the need for the professional to recognize the alveolisis and the possible associated complications as well as the appropriate way to manage them. A seemingly complex case was solved simply due to correct diagnosis and treatment(AU)

Angiogenesis and the prevention of alveolar osteitis: a review study

Angiogenesis is one of the essential processes that occur during wound healing. It is responsible for providing immunity as well as the regenerative cells, nutrition, and oxygen needed for the healing of the alveolar socket following tooth extraction. The inappropriate removal of formed blood clots causes the undesirable phenomenon of alveolar osteitis (AO) or dry socket. In this review, we aimed to investigate whether enhanced angiogenesis contributes to a more effective prevention of AO. The potential pro- or anti-angiogenic activity of different materials used for the treatment of AO were evaluated. An electronic search was performed in the PubMed, MEDLINE, and EMBASE databases via OVID from January 2000 to September 2016 using the keywords mentioned in the PubMed and MeSH (Medical Subject Headings) terms regarding the role of angiogenesis in the prevention of AO. Our initial search identified 408 articles using the keywords indicated above, with 38 of them meeting the inclusion criteria set for this review. Due to the undeniable role of angiogenesis in the socket healing process, it is beneficial if strategies for preventing AO are directed toward more proangiogenic materials and modalities.

Dry Socket Etiology, Diagnosis, and Clinical Treatment Techniques

Dry socket, also termed fibrinolytic osteitis or alveolar osteitis, is a complication of tooth exodontia. A dry socket lesion is a post-extraction socket that exhibits exposed bone that is not covered by a blood clot or healing epithelium and exists inside or around the perimeter of the socket or alveolus for days after the extraction procedure. This article describes dry socket lesions; reviews the basic clinical techniques of treating different manifestations of dry socket lesions; and shows how microscope level loupe magnification of 6× to 8× or greater, combined with co-axial illumination or a dental operating microscope, facilitate more precise treatment of dry socket lesions. The author examines the scientific validity of the proposed causes of dry socket lesions (such as bacteria, inflammation, fibrinolysis, or traumatic extractions) and the scientific validity of different terminologies used to describe dry socket lesions. This article also presents an alternative model of what causes dry socket lesions, based on evidence from dental literature. Although the clinical techniques for treating dry socket lesions seem empirically correct, more evidence is required to determine the causes of dry socket lesions.

Acutely infected teeth: to extract or not to extract?

Abstract: Not only laymen but also dentists generally believe that extraction of acutely infected teeth should be avoided until the infection subdues by using systemic antibiotics. The aim of this study was to compare perioperative complications in routine extractions of acutely infected teeth with extractions of asymptomatic teeth. This prospective study was performed with 82 patients. Severe pain on percussion of the relevant tooth was considered as basic criteria for acute infection. The acutely infected teeth were labeled as the study group (n = 35) and the asymptomatic teeth as the control group (n = 47). The extractions were done using standard procedures. The amount of anesthetic solution used and duration of extractions were recorded. Postoperative severe pain and exposed bone with no granulation tissue in the extraction socket were indications of alveolar osteitis (AO). The level of statistical significance was accepted as 0.05. Symptoms that could indicate systemic response, including fever, fatigue, and shivering were not found. There was no statistically significant difference between groups in terms of AO, amount of anesthetic solution used, and duration of extraction. The presence of an acute infection characterized by severe percussion pain is not a contraindication for tooth extraction. Infected teeth should be extracted as soon as possible and the procedure should not be postponed by giving antibiotics.

Chlorhexidine for prevention of alveolar osteitis: a randomised clinical trial

Abstract Objective To determine the effectiveness of chlorhexidine 0.12% mouthwash (CHX) after tooth extraction for the prevention of alveolar osteitis (AO). Material and methods We conducted a double-blind randomised clinical trial stratified by risk factors. We enrolled a cohort of 822 patients who underwent dental extractions, and were considered to be at risk of developing AO (previous surgical site infection, traumatic extraction, and tobacco smoking). After extraction, patients were randomly allocated for CHX group or placebo group, matched by risk factors. The primary outcome was clinical diagnosis of AO: increasing postoperative pain for 4 d within and around the socket, and total or partial breakdown of the blood clot in the socket with or without bone exposure. Results Follow-up was completed by 744 participants (372 chlorhexidine and 372 placebo). We detected no significant differences between the two groups at baseline. After completed follow-up, risk factors were equally distributed between the two groups. Overall incidence of OA was 4.97%, in which 27 participants treated with placebo (7.26%) and 10 participants treated with CHX (2.69%) developed AO. CHX reduced the incidence of AO by 63% [Absolute Risk Reduction: 4.57 (95% CI 1.5-7.7), Number Needed to Treat: 21.88 (95% CI 13.0-69.3), Fisher's exact test: p=0.006]. No adverse effects were reported. Conclusion The use of chlorhexidine 0.12% mouthwash after tooth extraction is safe and effective in reducing the incidence of AO in high-risk patients.

Platelet rich fibrin in the management of established dry socket

OBJECTIVES: Dry socket may occur secondary to the removal of any tooth. However, most dry socket cases develop in the third molar region. Dry socket is multifactorial in nature and has been treated using various modalities with varying success rates. This study assessed the efficacy of platelet rich fibrin (PRF) in established dry socket. MATERIALS AND METHODS: Ten patients of either sex aged from 41 to 64 years with established dry socket according to established criteria were treated using PRF. Evaluation was performed by observing the reduction of pain using visual analogue scale, analgesic tablet use over the follow-up period, and healing parameters. RESULTS: Pain was reduced on the first day in all patients with decreased analgesic use. Pain was drastically reduced during follow-up on the first, second, third, and seventh days with a fall in pain score of 0 to 1 after the first day alone. The pain scores of all patients decreased to 1 by the first day except in one patient, and the scores decreased to 0 in all patients after 48 hours. Total analgesic intake ranged from 2 to 6 tablets (aceclofenac 100 mg per tablet) over the follow-up period of 7 days. Healing was satisfactory in all patients by the end of the seventh day. CONCLUSION: PRF showed early pain reduction in established dry socket with minimal analgesic intake. No patients had allergic reactions to PRF as it is derived from the patient's own blood. PRF showed good wound healing. Our study suggests that PRF should be considered as a treatment modality for established dry socket.

Background: Impacted lower third molar surgery is a routine pro-cedure in the practice of oral surgery. However, there are various complications associated with the extraction of impacted mandibular third molars, the most common being pain, swelling, trismus, hemor-rhaging, ecchymosis, dry socket, infection, paresthesia, and diffi culty with chewing. Objectives: The aim of this study was to evaluate the incidence of postoperative complications following impacted lower third molar surgery in patients at the Academic Unit of Dentistry of the Autonomous University of Nayarit, so as to ensure these are taken into account and that the respective precautions are taken, either by attempting to avoid them in the future or to recognize and treat them. Pain, infl ammation and trismus are not analyzed in this paper. Material and methods: A longitudinal prospective study of 38 patients between the ages of 16 and 38 years old (with an average age 23.1) was carried out over seven consecutive days, with follow up examination performed at 15 and 30 days.
