354 - Occurrence of Approximal Lesions Following General Anesthesia Treatment on Primary Canines and Molars

Purpose: The purpose of this research study is to determine the outcome of untreated approximal surfaces of primary molars and canines at 6 month recalls for a period of 48 months following full mouth dental rehabilitation under general anesthesia.

Methods: Electronic chart and radiograph records of children 3 to 6 years of age who had dental treatment preformed under general anesthesia at El Rio Community Health Center from 1/01/2014 to 12/31/2017 were examined. The chart notes were reviewed and data recorded regarding age at time of treatment, gender, radiographic evidence of caries, restorations and extractions at 6 month increments for a period of 48 months.

Results: A total of 42 males (49.4%) and 43 females (50.6%) were included and the mean age was 4.2 years. A total of 276 canines, 56 first molars and 88 second molars were included in the study. In the 3 year old group, totaling 150 teeth, 66 developed caries resulting in 44 restorations. In the 4 year old group, totaling 150 teeth, 33 developed caries resulting in 16 restorations. The 5 year old group, totaling 89 teeth, 23 developed caries resulting in 14 restorations. The 6 year old group, totaling 31 teeth, 10 developed caries resulting in 6 restorations. 

Conclusions: In all 4 age groups, the canines exhibited lowest caries and restoration occurrence rates while first and second primary molar caries rate was nearly equal. However, 50% or greater of these caries occurrences still did not require restorations. Even within a high caries risk, low socio-economic status patient population, the practice approach of conservative, individual patient-based need for treatment should be the standard of care.
