RESUMEN
Introduction: The main cause for developing periapical lesions (PA) is the root canal infection. The mentioned causes may play a role in not controlling it but are not a "true" cause. Objective: To determine apical status and prevalence of endodontic treated tooth using radiograph assessment in relation to quality of root canal treatment and clinical factors among Saudi adults in the Eastern province. Patients and methods: This prospective case series study included 2161 patients who received root canal treatment (RCT) at Dammam Specialized Dental Center, Dammam Medical Complex, Ministry of Health, Saudi Arabia, between October 21, 2019 and April 22, 2020, after getting ethical approval from the Institutional Research Board (IRB). Saudi natives of either gender, age ≥ 18, with at least one fixed bridge or single dental crown evaluated on a clear, high-quality radiography image were recruited for the study. To determine the periapical state of root canal-filled teeth, the 'periapical index' (PAI) was used. All pertinent patient information was analyzed in SPSS verion-20 (IBM product, Chicago). Results: Out of 2161 cases, a PA lesion was present in 756 (35.0%). The prevalence of periapical lesions in endodontically treated teeth was 31.2%. PA lesion was associated with molar involvement (50.8% vs. 36.6%, p = 0.001), poor RCT quality (85.2% vs. 51.0%, p = 0.001), and smoking (13.6% vs. 10.5%, p = 0.028). According to logistic regression model, female gender, molar tooth, and poor RCT quality were more likely to expose PA lesion 1.5 times, 1.8 times, and 5 times, respectively. Conclusion: It is concluded that approximately 1/3rd of endodontically treated teeth are susceptible to the occurrence of periapical lesions in radiographic assessment, which are significantly associated with females, molars, and poor RCT quality, indicating a challenge for endodontists to improve their root canal assessment accuracy.
RESUMEN
BACKGROUND: A major shift has occured in the trend of dealing with dental caries from primary to secondary prevention, specially after SDF approval off-label by US FDA in recent years and Hall Technique (HT) in the last decade. OBJECTIVES: To determine the frequency of awareness and use of Silver Diammine Fluoride (SDF) and Hall technique among dental professionals in the Eastern province of Saudi Arabia. METHODS: This cross-sectional study was conducted in a public hospital, metropolitan city of Middle Eastern region between March 15, 2019 & January 31, 2020. Dental practitioners were requested, with their consent, to fill up a digitally designed survey. Chi-square test on SPSS-20.0 was applied to compare frequency of awareness and use of SDF and HALL Technique among the survey participants. RESULTS: The awareness of SDF was found to be 73.6% among specialists, 54.9% among graduates and 29.6% among students whereas awareness of HALL technique for stainless steel crown in pediatric dentistry was found statistically similar in all participants groups i.e. 42.7% in students, 55.5% in graduates and 54.9% in specialist group (p = 0.125). CONCLUSION: The results show potential with regards to awareness of dental specialists & postgraduate residents but inadequate among general dentists and students though all were keen advocates and found committed to its use to help the community. It points towards a further need of the of education for all groups. Those non- invasive techniques are very useful tools in general but specifically during Covid-19 pandemic where they can play a major role in preventing the spread of infection, arresting decay, alleviating pain and anxiety without resorting to aggressive treatment like pulp treatment/extraction. Low response rate may be improved in future through the respondents' counselling and regular follow up.
