Most Frequently Extracted Primary Tooth in Maxillary Arch of Children Visiting A University Hospital In Chennai: A Retrospective Study

Abstract

Early or premature loss is defined as the loss of a deciduous tooth before its time of natural exfoliation.The
disruption in the normal physiological process of deciduous tooth exfoliation and eruption of its successor
may cause a series of changes in the dental arches ranging from a change in arch length to malocclusion of
successive teeth. Premature loss of teeth can adversely affect oral health-related quality of life in children
. The main aim of this study was to investigate the most frequently extracted maxillary primary tooth in
children aged 1-15 years in Chennai, Tamil Nadu. This retrospective study was conducted among pediatric
patients who visited the OP of a university teaching hospital in Chennai during the period of June 2019 to
March 2020. The collected data was then subjected to statistical analysis using Statistical Package for Social
Science (SPSS). Descriptive statistics and Chi square tests were used. The most frequent age group was
the 7-12 years age group with 61.5% of the total population. Exodontia was most frequently seen in boys
with 53.9% of the total population.The most frequently extracted teeth was maxillary first right primary
molar with 17.8% followed by maxillary first left primary molar with 16.1%.Maxillary central incisors was
the most frequently extracted teeth in younger age group 1-6 years with right primary maxillary central
incisor 8.33% and maxillary left primary central incisor 7.95% of total population. Within the limits of the
study,Most frequently extracted tooth in the maxillary arch was the first primary molar. Exodontia was more
prevalent in the age group of 7-12 years. The most frequently extracted tooth in the younger age group (1-6
years) was found to be the central incisors.
