Patients were identified as SDF group (N = 335, 21.49%) or comparison (N = 1224, 78.51%). Dental treatments rendered were compared between the SDF and comparison group with multi-variable regression, including variables for demographics and clinical findings at baseline. The initial analysis identified variations in gender, age, dental pain, pulp involvement, and initial treatment plans between the SDF and comparison groups at baseline. In an unadjusted analysis, the SDF group displayed a statistically significant increase in the number of crown procedures but a notable decrease in the number of pulp therapy and extraction treatments completed (<i>p</i> < 0.05). An adjusted multivariable model affirmed the inverse relationship between SDF application and completion of pulp therapy and extractions at the time of GA (<i>p</i> < 0.05). No significant association was identified with the total number of crowns needed and SDF. The model further indicated a positive correlation between the total count of pulp therapy and extractions completed with patient age and the wait-time for GA. In conclusion, pre-GA application of SDF to carious primary teeth is negatively correlated with completed pulp therapy and extraction. SDF application prior to dental treatment with GA may be a valuable tool to reduce invasive dental procedures in GA.</p>","PeriodicalId":50235,"journal":{"name":"Journal of Clinical Pediatric Dentistry","volume":"48 5","pages":"174-182"},"PeriodicalIF":1.5,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142299880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The translation of the Child-OIDP index from English to Urdu was performed, and the content and face validity of the initial Urdu version were evaluated by experts and 11-12-year-old children, respectively. The psychometric properties of the Urdu Child-OIDP were assessed by administering the index to 264 children aged 11-12 from five schools in the Lahore district. Psychometric properties were evaluated using criterion and construct validity, internal consistency, test-retest reliability, and global self-rated oral items, followed by an oral examination. The standardized Cronbach's alpha was 0.77, and the weighted Kappa was 0.94 (intraclass correlation coefficient = 0.98). The index exhibited significant associations with subjective outcome measures, dental problem history, and dental caries status (<i>p</i> = 0.001). Children reporting poor oral health, lower satisfaction with oral health, and experiencing oral impacts demonstrated higher Child-OIDP scores. Additionally, children with dental caries and perceived treatment needs exhibited higher Child-OIDP scores, indicating poorer Oral Health-Related Quality of Life (OHRQoL). The prevalence of oral impacts was 88.3% (mean score = 17.8, standard deviation (SD) =14.7). Eating performance was the most affected while speaking was the performance least affected, while toothache and sensitive teeth were identified as the two most common causes of oral impacts.

Scopus, Medline and Web of Science databases were searched according to specific inclusion and exclusion criteria. Inclusion criteria included randomised trials that compared traditional methods of oral health education with game-based interventions in preschoolers and school-age children. The quality of the data was determined using Cochrane risk-of-bias tool for randomized trials (ROB-2). A total of seven studies that examined 1097 children (4-12 yrs) were included in this systematic review with the association of game-based teaching of oral health. The findings indicated that the utilization of game-based methods significantly improved children's oral health outcomes when compared to traditional teaching approaches. Specifically, the game-based interventions demonstrated positive effects on various aspects of oral health, including enhanced oral health knowledge, improved oral hygiene scores, and reductions in debris and plaque scores. The game-based interventions were found to be more effective in promoting oral health when compared to conventional methods of teaching, such as verbal instructions or educational posters.
