    Although complex phenomena such as oral diseases can be studied using generalizable conceptual frameworks, the differences in the underlying influences across countries necessitate adaptation of existing oral health frameworks to the specific conditions in each country. The aim of this dissertation was to investigate distal (indirect) and proximal (direct) influences of oral health and their interactions with both self-reported oral pain (OP) and self-rated oral health status (SROH) in Saudi Arabia (SA). Two secondary data analyses were conducted utilizing data from the national demographic and health survey (DHS) of SA in 2017. The objective of the first study was to describe the study design, and the distal and proximal influences reported in the 2017 SA DHS. The objective of second study was to explore associations between proximal and distal factors that affect OP and SROH, using the adapted framework. Path analysis modeling was used to estimate direct, indirect, and total effects. The 2017 SA DHS used an innovative multistage stratified random-sampling technique to select the population sample by using primary health care centers’ catchment areas as the primary sampling unit. The final analysis included 29,274 adults, 9910 adolescents, and 11653 children. OP in the past year was experienced in 39% in children and, 48.5% for the adolescents, and 47.1% in adults. The proportion of respondents who reported good, very good, or excellent self-rated oral health status was 92.9 % in children, 87.1% in both adolescents and adults. In children group, OP was linked to less tooth brushing, more dental visits and less dental routine examination, while less favorable SROH was linked to less tooth brushing, more dental visits and sweets consumption. In adolescents and adults groups, OP and less favorable SROH were linked to more dental visits, complaint dental visits, less tooth brushing. Many distal influences showed significant effects (direct, indirect, and total) on OP and SROH; however, differences existed among the three age groups. The studies suggest that future investigations should focus on why Saudi residents perceive their oral health positively while the prevalence of negative oral health influences and OP was high.

    The Saudi Arabian national demographic and health survey, 2017: Study design and oral health-related influences
    (Elsevier, 2023-01) Abogazalah, Naif; Yiannoutsos, Constantin; Martinez-Mier, Esperanza-Angeles; Tantawy, Muhammad; Yepes, Juan Fernando; Pediatric Dentistry, School of Dentistry
    Objective To describe the study design, and the distal and proximal influences on oral health reported in the national demographic and health survey (DHS) of the Kingdom of Saudi Arabia (KSA) in 2017. Methods The 2017 KSA DHS used an innovative multistage stratified random-sampling technique to select the population sample by using primary health care centers’ (PHCs) catchment areas as the primary sampling unit. Over 45,000 household heads plus a family member were interviewed. A conceptual framework for distal and proximal oral health influences specific to the KSA was adapted based on the oral health surveillance model. Cross-tabulation and Chi-square tests were performed with consideration for sample weights to provide estimates representative for the KSA population. Frequencies and weighted percentages for each variable reflecting each construct were reported. Results The total number of individuals included in the analysis was n = 55,511, ages ranging between 2 and > 65 years. Lack of dental care when needed was reported for 22.5 % of the population (males = 20.8 %/females = 24.7 %). Proportion of population from Central, West, East, South, and North regions who reported available dental care services when needed was 62.3 %, 58.0 %, 58.9 %, 62.3 %, and 60.1 %, respectively. PHCs were the most regular source for dental care (55.1 %). In total, 48.3 % visited the dentist at least once last year (males = 49.4 % /females = 46.8 %). Dental pain was the most common reason for last dental visit (69.0 %), while only 6.4 % reported visited the dentist for routine visit. Only 15.3 % reported brushing their teeth at least twice per day (males = 14.6 % /females = 16.4 %). Conclusion Two major oral health influences previously reported to have a significant negative influence on oral health, namely, limited routine dental check-up visits and inadequate oral hygiene, were present among KSA residents. Further inferential study is needed to investigate such influence on oral health status within the KSA population.

    Success Rates of Pulpotomies Performed by General Dentists Versus Pediatric Dentists: A Claims Data Analysis
    (American Academy of Pediatric Dentistry, 2020-07) Yepes, Juan Fernando; Schweppe, Jeff; Jones, James; Tang, Qing; Eckert, George J.; Downey, Tim; Maupome, Gerardo; Pediatric Dentistry, School of Dentistry
    Purpose: The purpose of this study was to examine if there are differences in the success rate of primary teeth treated with pulpotomies performed by general dentists (GDs) versus pediatric dentists (PDs), using submitted paid insurance dental claims. The extraction time after pulpotomy was examined. Methods: Data for this study were obtained from a private dental insurance claims warehouse. The insurance claims data were retrieved, and a retrospective analysis was performed over seven years (2008 to 2015). The survival rate was estimated using proportional hazard survival analysis. Results: The total number of paid dental claims that used the CDT code for pulpotomy was 401,638. For teeth that received pulpotomy, the average time between pulpotomy and extraction was 1.1 years if the pulpotomies were performed by GDs. The average time was 1.3 years if the pulpotomies were performed by PDs (P<0.0001). GDs had an extraction rate of 7.83 percent after pulpotomies and the placement of stainless steel crowns, while PDs had an extraction rate of 4.09 percent. Conclusions: There is a significant difference in the success rate of teeth treated with pulpotomies performed by pediatric dentists versus general dentists, with pulpotomies performed by the former having a longer survival rate.
