Objective: To assess the incidence of caries in a two-year period among low birth weight (LBW), very low birth weight (VLBW), and extremely low birth weight (ELBW) children considering socioeconomic indicators, dietary factors and oral hygiene. Material and Methods: A convenience sample was formed of 42 low birth weight children aged two to five years at baseline. Two examiners diagnosed caries using the World Health Organization criteria. Birth weight, socioeconomic indicators and diet were collected from medical records and questionnaires. Binomial models were used to estimate unadjusted and adjusted rate ratios (RR) and respective 95% confidence intervals for the factors evaluated. Results: Thirty-six children were re-examined after two years. The incidence of dental caries was 36.7%. The dmft index was 0.44 (±1.25) at baseline and increased to 1.36 (±3.85) at follow-up. VLBW children (1,000 to 1,500 g) (RR=0.23; 95%CI: 0.08-0.72) and LBW children (1,500 to 2,500 g) (RR=0.06; 0.01-0.55) had fewer carious lesions compared to ELBW children (<1,000 g). Carious lesions were more frequent among children with a lower income (RR=6.05; 1.05-34.84) and less frequent among those who did not consume sweetened juice, tea or yogurt (RR: 0.21; 0.07-0.62). Conclusion: An inverse dose-response relation was found between birth weight and the incidence of caries. A lower income and the consumption of sweetened beverages were risk factors for the development of caries.
The aim of the present study was to investigate the frequency of missing data on routine dental care appointments and restorative procedures from the clinical records of children treated at a pediatric dental clinic. A descriptive retrospective study was conducted involving the clinical records of children three to 12 years of age treated only with restorations. The inclusion criteria were clinical records from the past 10 years of children with at least one restored tooth. Data collection was performed by a trained examiner who extracted information from the clinical records on appointments for routine dental care and restorative procedures. The frequency of missing data on clinical records was submitted to descriptive analysis. Among the 249 clinical records analyzed, boys accounted for little more than half (54.2%) and mean patient age was 6.9± 1.8 years. Ninety-four of the 249 clinical records were of appointments for routine dental care. Missing data were found for the gingival bleeding index (18.1%), visible plaque index (22.3%) and dietary logs (74.5%). Forty-seven children were submitted to a total of 618 restorative procedures. Information was missing on the type of restorative material (5%), brand of the material used (65.2%), the type of isolation (50.8%) and whether pulp capping was performed (75.9%). The percentage of missing data from clinical records was substantial, demonstrating that important information is not recorded during routine dental care or restorative procedures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
