Prevalence of dental caries in Pakistan: a systematic review and meta-analysis.

BACKGROUND: Optimum oral health is impossible to achieve without managing dental caries. The first step to manage dental caries at a community level is to know its prevalence and trend. Unfortunately, the prevalence of dental caries at the national/regional level is not known in many developing countries. Pakistan is no exception. The present meta-analysis was planned to document the prevalence of dental caries at the national, as well as regional level. This paper will serve as a baseline for making future health policies, and health promotion activities in the country. METHODS: Literature was searched through various databases, such as PubMed, SCOPUS, and Web of science using: "Prevalence", "Dental Caries", "Dental Decay" and "Severity" as keywords. Any study that reported the prevalence of dental caries, and was conducted in the Pakistani population was included. Thirty studies fulfilled the inclusion criteria. Quality assessment of all the included studies was performed using Joanna Briggs Institute (JBI) critical appraisal checklist for prevalence studies. MedCalc software was used to analyze the data. RESULTS: In total 27,878 subjects were included in a meta-analysis from 30 studies. The prevalence estimate of dental caries at the national level was 56.62% (95% CI: 49.54 to 63.57). The I2 value was 99.07% (95% CI: 98.94 to 99.18), (I2 > 75%) indicating heterogeneity, hence pooled proportion was reported using a random-effect model. The prevalence estimate of dental caries in Sindh was 58.946% (95% CI: 43.796 to 73.274), and in Punjab, it was 55.445% (95% CI: 44.174 to 66.44), whilst in Baluchistan and KPK combined was 51.168% (95% CI: 22.930 to 79.004). CONCLUSION: Based on the existing data nearly 60% of the Pakistani population have dental caries. The proportion is almost the same in all provinces. Most of the included studies were found to be of high risk.

Oral Health-related Knowledge and Assessment of Oral Health Status of Diabetic Patients Attending Dental Clinic at College of Dentistry, Hail, Kingdom of Saudi Arabia.

AIM: This study was aimed to evaluate the oral health status and knowledge of diabetic and nondiabetic patients attending dental clinic at College of Dentistry, Hail, the Kingdom of Saudi Arabia. MATERIALS AND METHODS: It was an observational cross-sectional study. Using nonprobability convenient sampling technique, data were collected from 202 respondents. A total of 202 diabetic and nondiabetic patients were screened for the study. Data were collected by interview using the structured, self-administered questionnaire, and assessment of oral health status was done by clinical examination. The collected data were analyzed using IBM SPSS software. The data were displayed as numbers and percentages and association among the variable of interests was measured using Pearson Chi-square. RESULTS: Of the 202 patients, 102 (50.6%) were males and 100 (49.4%) were females. Majority of the patients, 71 (35.2%) were in the age-group of 30-40 years. In all, 128 (63.4%) participants knew the effect of diabetes mellitus (DM) on oral health, 167 (82.7%) knew that diabetic patients needed special healthcare, 152 (75.25%) had never spoken to their doctors about oral health, and 164 (81.19%) had never spoken to their dentists regarding diabetes. CONCLUSION: The complications associated with oral health are more common in diabetic patients when compared to the nondiabetic patients. This is the case in both male and female patients visiting the College of Dentistry in the Hail region. CLINICAL SIGNIFICANCE: Diabetes mellitus is associated with increased susceptibility to oral infections especially periodontal disease. Role of a general dentist in diagnosis and raising patient awareness toward DM and its effects on oral health need to be emphasized.

Prevalence of Dental Fluorosis in Saudi Arabia: A Meta-Analysis

Abstract Objective: To identify the prevalence of dental fluorosis in Kingdom of Saudi Arabia. Material and Methods: Literature search for the present study aimed to include all the relevant studies conducted in Saudi Arabia that reported prevalence of dental fluorosis. A literature search was done using keywords (dental, fluorosis, prevalence) using three databases (Scopus, PubMed, and Web of Science). Grey literature was also searched using Google Scholar and research gate. Literature was searched from 1939 till April 2020. The risk of bias was reported using JBI Critical Appraisal Checklist for Studies Reporting Prevalence Data. Twelve studies were included based on inclusive criteria. The only inclusive criteria were studies that were conducted among people living in Saudi Arabia, and studies that reported the prevalence of dental fluorosis. Samples from all age groups that reported prevalence of dental fluorosis were included. MedCalc statistical software was used to perform the analysis. Results: The overall prevalence of dental fluorosis was found to be 46.52%, 95 CI (26.52% to 67.12%). I2 value was reported 99.8%, 95 CI (99.78% to 99.83%), indicating high heterogeneity amongst the finding of studies. Funnel plots indicate the presence of a strong publication bias. Overall, we found some contrasting findings. One study reported prevalence of dental fluorosis as 0% and other with a comparatively large sample size found dental fluorosis to be 90.6%. Conclusion: The present study adds to the literature regarding dental fluorosis in Saudi Arabia by providing an overview of its prevalence. It is concluded that prevalence of dental fluorosis was a bit high. However, findings indicate publication bias. We did not account for severity of dental fluorosis. All the available data was analyzed to measure dental fluorosis prevalence without considering the sample size and sampling technique.
