Most Frequently Extracted Permanent Tooth in Patients Below 18 Years of Age Visiting a University Hospital in Chennai –A Retrospective Study

Abstract

The extraction of permanent teeth should not be an insignificant act, specially in children, because of the
terrible repercussions on eruption phenomena, the harmony of the arches, the primary capabilities of chewing,
swallowing, breathing and phonation. Loss of permanent teeth has negative consequences functionally,
psychologically and socially, especially for children and adolescents. The aim of this study is to analyse
the most frequently extracted permanent tooth and to evaluate the reasons for extractions in patients below
18 years of age visiting a university hospital in Chennai in a period of 10 months from June 2019 March
2020. The data of 7415 patients was reviewed and patients from 6-18 years of age undergoing permanent
teeth extraction were selected for this study. Chi-square test was used to detect the significance between age,
gender, reasons, and extracted tooth number. P value less than 0.05 was considered statistically significant.
In this study we observed that the most frequently extracted permanent teeth in patients from 6-18 years of
age are upper premolars, followed by lower first molars and the main reason for extractions were therapeutic
& dental caries. Within the limits of this study, the most frequently extracted permanent teeth in patients
from 0-18 years of age is upper premolars, followed by lower first molars and the main reason for extractions
