The Influence of Anxiety on Postoperative Quality of Life Regarding Implant Treatments: An Epidemiological Study.

Dental treatment anxiety is highly prevalent worldwide. This is particularly important in the field of implantology since, in daily clinical practice, it translates into an increase in the difficulty of treatments, extending surgical times and having repercussions in the postoperative period. The aim of this multicentre, cross-sectional, epidemiological study was to determine the influence of anxiety levels in the postoperative period of an implant treatment on patients treated at two dental departments in Extremadura (Spain). To analyse anxiety levels, the modified Corah's Dental Anxiety Scale questionnaire was administered before surgical treatment. To analyse the postoperative period, another questionnaire was provided 7 days after surgery. The study was conducted on a total of 102 patients (55 men and 47 women), with a mean age of 47.99 years. The results indicated that patients with a high and severe degree of anxiety had a poorer quality of life in general. Patients with a higher degree of anxiety perceived greater swelling at 24, 48, 72 h and one week after surgery.

Reduction by air purifier of particulate concentration during orthodontic procedures: a pilot study.

BACKGROUND: The SARS-CoV-2 pandemic has raised awareness of the importance of air quality. This pilot study arose from the need to reduce the concentration of particulate matter in the dental office during orthodontic procedures. To evaluate the efficacy of using an air purifier during orthodontic care in the dental office to reduce the concentration of ambient particulate matter. RESULTS: Significant reductions in particle numbers were obtained for all particle sizes except the largest particles counted (10 µm) through use of the air filter. A marked association between higher humidity levels and higher particle counts was also observed. CONCLUSIONS: Using an air purifier during dental care achieves a significant reduction in the concentration of ambient particles in the dental office. There is a correlation between higher relative humidity and higher particle concentration. The probability of obtaining a maximum particulate concentration level of 0.3 and 0.5 µm is 1000 times lower when using an air purifier.

Piperacillin-Tazobactam as an Adjuvant in the Mechanical Treatment of Patients with Periodontitis: A Randomized Clinical Study.

In this study, the aim was to evaluate the effects of the adjuvant piperacillin-tazobactam solution in the mechanical treatment of periodontitis. A single-blind split-mouth randomized study, it included 24 participants. All of them presented periodontitis stage III according to the 2018 World Workshop classification and the presence of at least one of the following periodontal pathogens: Aggregatibacter actinomycetemcomitans; Porphyromona gingivalis; Treponema denticola; Tannerella forsythia; Prevotella intermedia. The study established two groups: a control group (SRP: scaling and root planing) and a test group (SRP plus local piperacillin-tazobactam). The final recruitment included 11 women (45.8%) and 13 men (54.2%). The age range was between 25 and 72 years, and the mean age was 57 ± 10.20 years. Clinical controls were performed at 2 weeks, 3 months, and 6 months, repeating the SRP and applying the piperacillin-tazobactam solution again at the 3-month appointment. The clinical attachment level decreased by a mean of 2.13 ± 0.17 mm from the baseline to 6 months in the test group versus 1.63 ± 0.18 mm in the control group. The mean probing pocket depth decreased from 1.32 ± 0.09 mm in the test group, versus from 0.96 ± 0.14 mm on the control side. The plaque index in the test group decreased by 0.46 ± 0.04, while it decreased by an average of 0.31 ± 0.04 in the control group. In conclusion, the local use of piperacillin-tazobactam as complementary therapy produces better clinical results in patients with periodontitis. However, these results are not maintained over time, and so a more persistent local application is necessary.

Dental Transmigration: An Observational Retrospective Study OF52 Mandibular Canines.

The aim of this study was to analyze the prevalence of transmigrated canines in a Spanish population by evaluating their clinical and radiological characteristics. The descriptive observational study obtained 6840 orthopantomographs from all patients seeking dental care in the years 2017-21 via the Patient Reception Service and Dentistry Service at the Faculty of Dentistry at the Complutense University of Madrid and the Central Hospital of the Red Cross of Madrid (Spain). In total, 52 patients presented transmigrated canines, establishing a prevalence of 0.76%. This sample comprised 28 women and 24 men. Whenever a transmigrated canine was identified, a CBCT scan was obtained and used to evaluate the clinical and radiological variables associated with canine transmigration. The predominant side of the transmigration was the left (57.69%) compared to the right side (42.30%). The position of the canine, in order of frequency, according to the Mupparapu classification, corresponded to type IV (42.30%), type II (36.53%), type I (15.38%), and type V (5.76%), with no type III transmigrations found. Clinical manifestations were only recorded in 17.30% of cases, and 11.53% of the radiological findings showed the presence of tooth cysts that were confirmed by histopathological studies. Other impactions, in addition to the transmigrated canine, were found in five patients (9.61%), with the majority being the presence of third molars.

Influence of Serum Vitamin D Levels on Survival Rate and Marginal Bone Loss in Dental Implants: A Systematic Review.

This systematic literature review set out to investigate the relationship between serum vitamin D levels and dental implants in terms of survival rates, marginal bone loss, and associated complications. The review was conducted according to PRISMA guidelines, performing an electronic search in four databases (Pubmed, Web of Science, Cochrane, and Scopus), complemented by a manual search up to April 2022. Four articles were selected for analysis. The Newcastle-Ottawa Quality Assessment Scale tool was used to assess the quality of evidence of cohort studies, and the Cochrane bias assessment tool was used to assess the quality of evidence of randomized clinical trials. The study included 1089 patients restored with 1984 dental implants, with follow-up periods ranging from 20-240 months. Cases presenting lower serum vitamin D levels obtained slightly worse results in terms of marginal bone loss. Longer follow-up periods are needed in order to determine whether serum vitamin D levels affect implant survival rates and osseointegration over time.

Clinical Evaluation of Dental Implants with a Double Acid-Etched Surface Treatment: A Cohort Observational Study with Up to 10-Year Follow-Up.

BACKGROUND AND OBJECTIVES: The main purpose of this study was to evaluate the survival and success rates of dental implants with a double acid-etched surface treatment with evaluation times up to 10 years post-loading. Materials and Methods: This study was conducted at a hospital oral surgery and implantology unit. It included 111 dental implants with a double acid-etched surface. Three groups were created: Group 1 (1-3 years loading), Group 2 (3-5 years loading), and Group 3 (over 5 years loading). Probing depth, resonance frequency analysis (ISQ value), and marginal bone loss were evaluated. Results: The data obtained underwent statistical analysis. Overall, 78 patients were included in the study, who received, in total, 111 dental implants, all replacing single teeth. Mean probing depth was 3.03 mm and mean ISQ was 65.54. Regarding marginal bone loss, in Group 1, 67.6% of implants did not undergo any thread loss, in Group 2, 48.3%, and in Group 3, 59.6%; 59.10% of all implants did not present thread loss with a mean bone loss of 0.552 mm. The implant survival rate was 99.1%, and the success rate was 96.37%. Conclusions: Implants with a double acid-etched surface showed excellent success rates in terms of marginal bone loss, ISQ, and probing depth after up to 10 years of loading, making them a clinically predictable treatment option. Future studies are needed to compare this implant surface with other types in different restorative situations.

Placing Dental Implants through Impacted Teeth to Support a Fixed Partial Denture in a Geriatric Patient as an Alternative to Invasive Extraction Surgeries.

Multiple dental impactions not associated with craniofacial syndromes are a rare condition and present the dentist with a therapeutic challenge when it comes to performing surgical/restorative treatments in adult patients. This case report describes a geriatric patient with multiple impacted teeth restored by means of two different protocols. In the second quadrant, an impacted tooth was extracted followed by regeneration and placement of an implant. In the third quadrant, implants were placed though impacted teeth for restoration with a fixed partial prosthesis. Placing dental implants through impacted teeth may offer a possible therapeutic option for implant-supported restorations in middle-aged or elderly patients, for whom surgery and orthodontic traction are not possible, and/or patients who refuse to undergo more invasive extraction surgery.

Safety and Efficacy of a New Synthetic Material Based on Monetite, Silica Gel, PS-Wallastonite, and a Hydroxyapatite Calcium Deficient: A Randomized Comparative Clinic Trial.

Background and Objectives: Maxillary bone defects related to post-extraction alveolar ridge resorption are usual. These defects may lead to failure in further surgical implant phases given the lack of bone volume to perform the dental implant. The objective of this clinical assay was to evaluate the safety and efficacy of an experimental synthetic bone substitute in the preservation of post-extraction maxillary alveoli. Materials and Methods: 33 voluntary patients who had at least one maxillary premolar tooth that was a candidate for exodontia (n = 39) and subsequent implant rehabilitation participated. The regenerated alveoli were monitored by means of periodic clinical examinations (days 9 ± 1, 21 ± 4, 42 ± 6, and 84 ± 6), measuring the height and width of the alveolar crest (days 0 and 180 ± 5), measurement of radiodensity using tomographic techniques (days 0-5 and 175 ± 5), and histological examination of biopsies collected at 180 ± 5 days. Results: No significant differences were observed during the entire follow-up period between the two groups with respect to the safety variables studied. A variation in width of -0.9 ± 1.3 mm and -0.6 ± 1.5 mm, and a variation in height of -0.1 ± 0.9 mm and -0.3 ± 0.7 mm was observed for experimental material Sil-Oss® and Bio-Oss®, respectively. The radiodensity of the alveoli regenerated with the experimental material was significantly lower than that corresponding to Bio-Oss®. However, the histological study showed greater osteoid matrix and replacement of the material with newformed bone in the implanted beds with the experimental material. Conclusions: Both materials can be used safely and proved equally effective in maintaining alveolar flange dimensions, they are also histologically biocompatible, bioactive and osteoconductive. The experimental material showed the advantage of being resorbable and replaced with newformed bone, in addition to promoting bone regeneration.

Desplazamiento accidental del tercer molar al seno maxilar: protocolo de actuación / Accidental displacement of the third molar into the maxillary sinus: action protoco

Introducción: El desplazamiento accidental del tercer molar hacia el seno maxilar es una complicación de la cirugía bucal. La extracción de estos dientes generalmente es compleja debido a la escasa visibilidad, el espacio limitado y la ubicación espacial del diente, por lo que se requiere tener un cuidado meticuloso durante el tratamiento. Objetivo: El objetivo de este artículo ha sido el de establecer un protocolo de actuación basado tanto en el tratamiento quirúrgico como farmacológico, y el seguimiento que este tipo de complicaciones necesita según la literatura. Caso clínico: Se presenta el caso clínico de un varón de 17 años de edad, sin antecedentes médicos de interés, que fue remitido por su odontólogo para proceder a la valoración y extracción quirúrgica del tercer molar superior izquierdo que había sido desplazado al interior del seno maxilar tras el intento de exodoncia, y que producía sintomatología compatible con sinusitis aguda. La exploración radiológica descartó la afectación del resto de senos paranasales y confirmó la obstrucción casi completa del seno maxilar izquierdo. La extracción del cordal se realizó mediante ostectomía de la pared anterior del seno, pautándose tratamiento farmacológico postoperatorio y controles periódicos durante el primer año. Discusión: La terapéutica recomendada para esta complicación incluye la recuperación inmediata del diente, o la extracción posterior mientras la fibrosis se desarrolla en torno al diente desplazado, según sea necesario, tomando en cuenta la infección, el rango limitado del movimiento de la mandíbula, o malestar psicológico del paciente. El tratamiento médico y farmacológico que debe prescribirse según la literatura revisada, para facilitar el drenaje sinusal y el control de la infección. Conclusión: Para evitar este tipo de complicaciones, conviene realizar un estudio radiológico completo en los casos de cercanía del tercer molar superior en las inmediaciones del seno maxilar, y valorar la disposición e inclinación del mismo

Introduction: Accidental displacement of the third molar into the maxillary sinus is one of the complications of oral surgery. These extractions are usually complex due to some factors such as low visibility, limited space and the location of the tooth; so special care on these treatments is required. Objective: To establish an action protocol based on a surgical as well as a pharmacological treatment, and the monitoring that this kind of complications need according to the literature. Clinical case: A 17-year old man, with a noncontributory medical history, was referred to our clinic by a colleague to evaluate and perform a surgical extraction of his upper left third molar, which had been displaced into the maxillary sinus after a failed extraction, and was generating symptoms of acute sinusitis. The radiographic examination dismissed the affectation of the rest of the paranasal sinuses and confirmed the almost totally blockage of the left maxillary sinus. The extraction of this third molar took place by means of an anterior-wall ostectomy of the sinus; afterwards a pharmacological treatment was prescribed and regular control visits along the first year were planned. Discusion:The suggested treatment for this kind of complications involves the immediate recuperation of the tooth or its later extraction meanwhile the fibrosis forms around the displaced tooth, as needed. We have to take into account the infection, the limited mandibular range of movement as well as the patient's psychological discomfort. The medical and pharmacological treatment should be prescribed following the reviewed literature, in order to obtain the sinusal drainage and the infection control. Conclusion: It is convenient to carry out an exhaustive radiological examination in case of close relation between the maxillary third molar and the maxillary sinus as well as evaluate its position and inclination to avoid this kind of complications

Application of the Social Appeal Scale to a Selected Spanish Population.

PURPOSE: The aim of this study was to validate the Social Appeal Scale (SAS) among the Spanish general population, exploring the underlying dimensions of the construct assessed. MATERIALS AND METHODS: The SAS test was applied to 555 participants between 16 and 75 years of age. The scale is divided into four dimensions: social competence (SC), intellectual ability (IA), psychologic adjustment (PA), and relationship satisfaction (RS). RESULTS: The SAS (12 items) had a Cronbach alpha of .93, and SC had a Cronbach alpha of .83. For IA it was .85, for PA .87, and for RS .84. CONCLUSION: Bearing in mind the limitations of the present study, it may be concluded that the Social Appeal Scale is a valid and reliable instrument to assess social perceptions related to changes in tooth color.

Reconstrucción con injertos de la cresta iliaca y rehabilitación con implantes en atrofia del maxilar. Caso clínico / Reconstruction with iliac crest grafts and rehabilitation with implants in atrophic maxilla. Case report

Introducción: En muchos casos, la rehabilitación de pacientes que sufren atrofia maxilar severa es muy difícil. En estas situaciones, el uso de hueso autógeno conlleva unas ventajas debido a su capacidad osteogénica, osteoconductiva y osteoinductiva, además de ser biológicamente compatible. Se prefiere la cresta ilíaca cuando se requieren grandes cantidades de tejido óseo. Objetivo: El objetivo del presente artículo ha sido exponer un caso de reconstrucción ósea con injertos de cresta iliaca y posterior rehabilitación con implantes tras un seguimiento de diez años. Caso clínico: Se presenta un caso de una mujer de 36 años, que acudió a consulta por presentar inestabilidad de su prótesis removible completa superior. Tras el estudio tomográfico, se observó atrofia severa antero posterior, por lo que se informó a la paciente de la posibilidad del aumento óseo mediante injertos procedentes de la cresta ilíaca. Se realizó la intervención y después de 6 meses se colocaron 6 implantes. Tras 4 meses, se procedió al descubrimiento de los implantes y a la confección de una sobredentadura. La primera revisión se le realizó a los 6 meses y posteriormente al año, a los dos y medio, a los cinco y a los diez años, donde se objetivó un resultado satisfactorio. Conclusiones: La supervivencia de los implantes situados en las zonas reconstruidas con injertos en bloque de la cresta ilíaca, en nuestro caso, ha sido comparable a la supervivencia de los implantes en hueso nativo

Introduction: In many cases, the rehabilitation of patients with severe atrophy maxillary is very difficult. In this situation, the use of autogenous bone entail some advantages due to their osteogenic, osteoconductive and osteoinductive potential, as well as being biologically compatible. The iliac crest is preferred where large amounts bone tissue are required. Objective: The objective of this article was to show a case of bone reconstruction with iliac crest grafts and posterior implant rehabilitation follow-up for more than ten years. Clinical case: A case is presented a 36 years old woman, who went to the consultation due to instability of the upper complete removable prosthesis. After the CT scan, antero-posterior severe atrophy was observed, so that the patient was informed of the possibility of bone augmentation by iliac crest grafts. The intervention was carried out and after 6 months the 6 implants were placed. After 4 months, implants were discovered and a over denture was concocted. The first review was performed at six months and a year later, two and a half, five and ten years, where a satisfactory outcome was observed. Conclusions: The survival of the implants in reconstructed areas with iliac crest grafts is comparable to the survival of the implants in native bone
