Endodontic treatment is common in dentistry and for a correct diagnosis it is necessary to observe clinical and radiographic signs, taking into account pulp and periapical changes in the element to be treated. Studying this frequency can contribute to the literature, elucidating whether the greatest number of cases is occurring in young or elderly patients, women or men, anterior or posterior teeth. The objective of this study was to analyze the prevalence of endodontically treated teeth, through 900 panoramic radiographs. A cross-sectional study was carried out evaluating the prevalence of teeth treated endodontically from a sample of 900 panoramic radiographs, corresponding to exams performed in 2020, in a radiological clinic located in central west Brazil. The sample consisted of 540 (60%) female subjects and 360 (40%) male subjects, aged between 18 and 88 years old, being more prevalent for Individuals <31 years old with (34.9%) Sample. The prevalence of endodontically treate...

The aim of this study was to assess the prevalence and risk factors of apical periodontitis in endodontically treated teeth in a selected population of Brazilian adults. A total of 1,372 periapical radiographs of endodontically treated teeth were analyzed based on the quality of root filling, status of coronal restoration and presence of posts associated with apical periodontitis (AP). Data were analyzed statistically using odds ratio, confidence intervals and chi-square test. The prevalence of AP with adequate endodontic treatment was low (16.5%). This percentage dropped to 12.1% in cases with adequate root filling and adequate coronal restoration. Teeth with adequate endodontic treatment and poor coronal restoration had an AP prevalence of 27.9%. AP increased to 71.7% in teeth with poor endodontic treatment associated with poor coronal restoration. When poor endodontic treatment was combined with adequate coronal restoration, AP prevalence was 61.8%. The prevalence of AP was low when associated with high technical quality of root canal treatment. Poor coronal restoration increased the risk of AP even when endodontic treatment was adequate (OR=2.80; 95%CI=1.87-4.22). The presence of intracanal posts had no influence on AP prevalence.

Objectives: This study aimed to evaluate the success rate of endodontic treatments performed by undergraduate students and the factors associated with the outcome. Materials and Methods: A follow-up of 3 to 8 years after root canal filling was carried out in 91 patients. At the follow-up visits, medical and dental history questionnaires were applied along with clinical and radiographic examinations. Data collected in the clinical exam included: the presence of pain, swelling, sinus tract, mobility, tenderness to palpation and percussion, periodontal probing profile, and type/quality of coronal restoration. Postoperative and follow-up radiographs were digitalized and analyzed by 2 trained and calibrated examiners to assess periapical healing. The treatment outcome was based on strict clinical and radiographic criteria and classified as success (absence of any clinical and radiographic sign of apical periodontitis) or failure (other combination). Logistic regression was used to investigate the impact of clinical and radiographic variables on endodontic treatment outcomes at a 5% significance level. Results: The success rate of endodontic treatments was 60.7%. The only risk factor significantly associated with failure was the presence of a periapical lesion on the postoperative radiograph (odds ratio, 3.35; 95% confidence interval, 1.17-9.54). Conclusions: The success rate of endodontic treatments performed by undergraduate students was low and was jeopardized by the presence of a periapical lesion on the postoperative radiograph.
Root canal morphology of 1316 premolars from Brazilian individuals publicado
Acta Odontol. Latinoam, 2022
The aim of this study was to investigate the internal root canal anatomy of maxillary and mandibular premolars in a Brazilian subpopulation, in order to establish the prevalence of the different configurations proposed by Vertucci. Three hundred and ninety-eight cone-beam computed tomography scans were collected from a private imaging clinic database in Rio de Janeiro, including 217 maxillary and 226 mandibular scans. A total 1316 premolars (594 maxillary and 722 mandibular) were evaluated using an image viewer, and classified according to Vertucci. Two calibrated examiners determined the frequency of each morphological Type. A third examiner reviewed discordant cases. The Kappa test was applied to verify inter-rater agreement, and Fisher's Exact Test to verify gender-related differences. The most frequent root canal configurations of maxillary first and second premolars were Type IV (73.86%) and Type I (47.18%), respectively. Type I was the most prevalent in mandibular first and second premolars (80.59% and 95.86%, respectively). Only Types I and VIII presented a statistically significant difference between sexes. Type I was more frequent in females and Type VIII in males. A highly significant frequency of Type I was found in both mandibular first and second premolars, whereas the most frequent maxillary premolar root canal configuration was Type IV for first premolars and Type I for second premolars.
Evaluation of Endodontic Treatments Performed by Students in a Brazilian Dental School
Journal of Dental Education, 2005
The aims of this study were to evaluate the clinical outcomes of root canal treatments performed by final‐year students in the Dental School of Piracicaba, State University of Campinas, SP, Brazil, during the year 2000 and to evaluate the success rate of these treatments at follow‐ups conducted one and three years later (2001–03). All 579 endodontic treatments performed by final‐year students were selected for this investigation. Detailed personal and dental history was obtained from the patient's records. Clinical and radiographic follow‐up examinations were performed. For 78.8 percent of the cases, dental caries was recorded as the cause for performing endodontic treatment; for 8.8 percent, prosthetic reasons were given; and for 12.4 percent, failure of the endodontic treatment was the reason. The largest percentage (30.7 percent) of recalled patients was examined after one year; the success rate at this follow‐up evaluation ranged from 83 percent to 96 percent depending on th...

This study investigated the prevalence of apical periodontitis (AP) and its association with endodontically treated teeth in residents of São Luís, MA, Brazil. Two-hundred complete series of periapical radiographs taken over a 10-year period (1993-2003) were retrieved from the files of four prosthesists and five periodontists. The Periapical Index (PAI) was used and the age range, sex, tooth groups, location and association with endodontic treatment (ET) were also analyzed. The Cohen Kappa and Chi-square tests were used for statistical analysis. Out of 200 patients, 135 presented at least one case of AP, which corresponds to a prevalence of 67.5%. Of the 5008 teeth examined, 296 had AP and 553 had ET. Therefore, considering the total number of teeth, AP and ET prevalences were 5.9% and 11%, respectively. Of the 553 endodontically treated teeth, 235 (42.5%) were associated with AP. Chi-square test showed a strong correlation between AP and ET (p<0.05). The 40-year-old age group wa...

Introduction: This cross-sectional study determined the prevalence of apical periodontitis in 1086 root canal-treated teeth from an urban Colombian population and evaluated the association of several factors with the periradicular status. Methods: Periapical radiographs were used for analyses, and teeth were classified as healthy or diseased according to the periradicular status. Other factors were also evaluated for their association with the periradicular conditions, including gender, quality of both endodontic treatment and coronal restoration, apical level of filling, and presence of post restoration. Results: Fifty-one percent of the treated teeth were classified as healthy. Only 33% of the teeth had endodontic treatment rated as adequate. The quality of both endodontic treatment and coronal restoration significantly influenced the periradicular conditions (P < .001). Combined data revealed that teeth with both adequate endodontic treatment and adequate restorations showed significantly better periradicular status than the other combinations (P < .01), except for teeth with adequate treatment and inadequate restoration (P = .08). Canals filled up to 0-2 mm short of the apex had a significantly higher number of teeth rated as healthy than overfilled or underfilled cases (P = .02). Regression analysis showed that the quality of endodontic treatment was the most significant factor influencing the periradicular status (P < .001). Gender and presence of post restoration had no association with the periradicular conditions. Conclusions: Data from this Colombian population showed a relatively high prevalence of apical periodontitis in root canal-treated teeth. This was largely due to an equally high prevalence of treatments performed under substandard technical quality. The quality of the endodontic treatment was the most determinant factor for healthy periradicular status. (J Endod 2013;39:600-604)

Aim: To determine the prevalence of apical periodontitis (AP) and the frequency of root canal treatment in a sample of Spanish adults. Design: A descriptive cross-sectional study. Setting: Barcelona, Spain. Participants: A total of 397 adult subjects, 49% males and 51% females. Methods: Digital panoramic radiographs were used. Periapical status was scored according to the periapical index. Results were analysed statistically using the chi-squared test and logistic regression. Results: Radiographic signs of AP in one or more teeth were found in 135 patients (34%). The prevalence of AP was significantly higher in males (42.3%) than females (26.1%) [odds ratio (OR) = 2.1; 95% confidence interval (95% CI) = 1.4-3.2; P = 0.0007]. At least one root-filled tooth (RFT) was found in 233 patients (59%). Twenty-six per cent of subjects with RFT had at least one RFT with AP. The prevalence of AP increased with age (P < 0.05). Patients with RFT showed a higher prevalence of AP (42%) relative to patients without RFT (23%) (OR = 2.4; 95% CI = 1.5-3.7; P = 0.00013). Adjusting for age, gender and teeth number, endodontic status remained significantly associated with periapical status (OR = 2.3; 95% CI = 1.4-3.6; P = 0.0005). Conclusions: Both the prevalence of AP and the frequency of root canal treatment are high among Spanish adults. AP affects more frequently RFT relative to untreated teeth. Patients with one or more RFT have a greater likelihood of having AP than patients without RFT.
