Iqra Gaffar and Zubair Hassan Awaisi
ABSTRACT
Objective: To determine the prevalence and distribution of tooth agenesis (the congenital absence of one or more teeth) in a specific orthodontic patient population.
Study Design: Prospective study
Place and Duration of Study: This study was conducted at the Orthodontic Department of the Nishtar Institute of Dentistry, Multan from March 2020 to February 2021.
Methods: A total of one hundred and seventy patients enrolled in the study. The study ensured that all patients who agreed to participate provided informed written consent and approval was taken from ethical committee of hospital. Main variables of study were age, gender, type of missing tooth and place of missing tooth (maxilla or mandible) and side of missing tooth (right or left). SPSS version 27 was used for data analysis.
Results: The mean age 15.33±3.28 years. There were 67.4% males and 32.6% females. Out of 270 patients, hypodontia was observed in 12 (4.4%) patients. It was noted that there were 45 missing teeth among 12 patients. In which 26 (57.8%) teeth were maxilla and 19 (42.2%) were mandible. In maxilla, 10 (38.5%) were right and 16 (61.5%) were left. Whereas, in mandible there were 15 (78.9%) right and 4 (21.1%) left.
Conclusion: Study's findings regarding the occurrence of hypodontia are consistent with what has been reported in existing literature. The anterior segment of the dentition is particularly affected by hypodontia. Furthermore, early detection of hypodontia is important because identifying the condition at an early stage allows for more effective planning and treatment.
