Aim: The aim of this study was to detect white spot lesions (WSL) on the surfaces of the teeth and devise a new classification system to classify WSL based on their location/site of occurrence pertaining to primary dentition.
Materials and methods: A total of 300 children were assessed, out of which, 271 participants were detected with WSL. Each tooth detected with white spots was analyzed based on their occurrence on the surface of the tooth. Descriptive statistics was performed using SPSS software.
Results: Based on their site of occurrence in the maxilla and mandible, WSL were greatest on the cervical region of incisors (60.5% and 43.8%), middle region of the canines (82.3% and 87%), and proximal regions of molars (88.5% and 98%).
Conclusion: Based on the results, a new system of classification for WSL in primary dentition is devised. It combines ICDAS II criteria (code 1 and 2) along with the site of occurrence of the lesion. The knowledge of its location on the surface of tooth aids in registering the remineralizing effects of the prescribed remineralizing agents during follow-up.
Clinical significance: The classification allows for easy identification of white spots between observers and the positive effects of various remineralising agents can be appreciated if the appropriate site was already known.
