Prevalence of Dental Caries in Permanent Second Molars in Teenagers Using ICDAS

Introduction: Dental caries is a chronic disease of the tooth which is represented by demineralisation and destruction of the organic matter of the tooth. Dental caries are versatile, capable of affecting the crown portion of the tooth initially, and may affect the unprotected root surfaces later on. International Caries Detection and Assessment System (ICDAS) provides a systematic approach of reviewing the available clinical dental caries to evaluate the development of dental caries

Materials and Methods: This study is a single centered retrospective study in which the data was collected from a private dental college and hospital in Chennai, India. Patient details were collected from the hospital management system and a total of 1804 samples were collected. The data was tabulated using Excel and then statistically analysed using the latest version of SPSS software.

Results and Discussion: The prevalence of ICDAS score 3 in second molars is higher in 17 year old patients with 2.88% in maxillary right second molars, 3.33% in maxillary left second molars, 3.55% in mandibular left second molars and 3.71% in mandibular right second molars. The prevalence of dental caries in permanent second molar is 9.34%. It is seen that ICDAS score 3 is 8.71% prevalent followed by ICDAS score 5 which is 0.63%.

Conclusion: Within the limitations of the study, it was found that the prevalence of dental caries in permanent second molars is 9.34% with ICDAS score 3 being the most prevalent followed by ICDAS score 5 which is 0.63%.
