Approximal Caries Lesion Progression Rate In Young Adult Population
Objectives:
To describe the approximal caries lesion progression rate in a Chilean young adult population, using retrospective data collected through bitewing radiographs. Survival analysis was performed globally and site-specific to obtain progression rate.
Methods:
Data was collected from clinical charts and bitewing radiographic exams between 2010 and 2016 from patients receiving treatment at Pontifical Pontifical Catholic University Student’s Health Department. Kaplan-Meier Survival analysis for approximal caries was done for enamel and dentin in general, and by surface using at least two BW radiographs. (Fig 1)
Results: 372 individuals were included in the analysis, the mean age was 21,5 years and mean DMFT was 5,1. From them, 45,2% were in need of restorative treatment with at least one evident cavitated lesion at clinical exam. 70,4% had at least one restoration and 83.1% had caries experience (DMFT different than 0). Positive correlation was found between higher component F and older age. General survival analysis showed that by location, maxillary teeth survive less than mandibular ones; by type of teeth, premolars survive less than molars; and by gender, higher survival was found in men. A tendency of less progression rate at older age was found. For survival rates, only 50% of enamel lesions progressed to outer dentin after 8.4 years. When caries lesion was found in outer dentin, caries progression was found to be faster: 50% progressed in 3.5 years. Detailed progression rates can be found on fig 2.
Conclusions: Progression rate in chilean young adults was found to be similar as research published by scandinavian countries with lower prevalence of caries and stronger prevention policies. Based on the findings of slow progression rate reported, we suggest clinicians to enhance non operative treatments before making the decision of intervene invasively.
