112 - Retrospective Caries Progression in Primary, Permanent, and SDF-Treated Teeth

Abstract:

Purpose: The purpose of this study is to evaluate the progression of incipient dental enamel lesions in children between 2020-2024 in San Diego.

Methods: This retrospective study includes patients between 3 to 16 years old seen at the pediatric dental residency program based in San Diego. Three calibrated sub-investigators evaluated baseline and two periodic radiographs over a period of 12 months for radiographic lesion progression. Interproximal lesions were evaluated using the ICCMS system and categorized based on non-SDF treated primary or permanent dentition versus SDF-treated primary or SDF- treated permanent dentition. Outcomes were recorded as no progression, progression, regression, or restored.

Results: Out of the non-SDF treated primary lesions, 65% progressed passed the DEJ (R3) or required treatment, versus 46% of non-SDF treated permanent lesions that progressed or required treatment (P=.012). Out of the non-SDF treated lesions, 20% were restored within 12 months versus 4.5% of SDF treated lesions being restored (P=.02).

Conclusion: Carious lesions on primary teeth were more likely to progress over 12 months compared to permanent teeth. Carious lesions treated with SDF were significantly less likely to be restored than non-SDF treated lesions.
