Introduction: Dental caries can affect the tooth crown and, later in life, exposed root surfaces, and can occur in both
primary and permanent dentitions. Preservation of both primary and permanent teeth during the functional dentition period is
essential for proper oral hygiene. Endodontic treatment is a procedure that is carried out to maintain the health of pulp. The outcome
of root canal therapy is immediately dependent on proper root canal cleaning and shape, while the long-term prognosis of a root
canal treated tooth is more dependent on obturation quality. Aim: The aim of the study was to radiographically assess the quality
of obturation in root canal treated teeth in patients under the age of 17. Materials and methods: The study was carried out from
June 2020 to March 2021 on 134 patients ( 79 males and 55 females) who visited Saveetha dental College and Hospital, Chennai.
Data collection included age, gender, tooth number and level of obturation and association between these were obtained using
pearson’s chi-square test. Results: In this study we observed that the majority of males (59%) under the age of 17 had undergone
root canal treatment. Based on the age categorisation, 57.5% patients belonged to the 11-15 years age group which was the highest.
In this study it is seen that the most frequently reported tooth for root canal treatment was the Mandibular molars (41.8%). Based
on the quality of obturation, it is seen that the majority of the root canal treated tooth for patients under the age of 17 had been
obturated at the level of apex (56%). Conclusion: In this study it is seen that, root canal done by post graduates was mostly
commonly in Mandibular molars and the quality of obturation was at the level of apex.
