Analyzing Tooth Extraction Pattern in Orthodontics: A Comprehensive Study on Demographics and Malocclusion Factors

Abstract

This study investigates the patterns of tooth extraction in orthodontic treatment, focusing on demographics and

malocclusion factors. Understanding these patterns is crucial for optimizing dental alignment and improving overall dental

function and aesthetics. To determine the frequency and distribution of tooth extraction patterns in orthodontic patients and

explore the relationship between extraction patterns and demographic characteristics, malocclusion types, and treatment

outcomes. This study was conducted at the Department of Orthodontics, Khyber College of Dentistry, Peshawar, over four

months (March to June 2023), this study included 370 patients aged 15 to 40 years. Using non-probability convenient

sampling, data on demographics, extraction patterns, and malocclusion types were collected from patient records. Ethical

approval was obtained, and data analysis was performed using SPSS version 26. The sample comprised 177 males (47.8%) and

193 females (52.2%). Age distribution was 15-20 years (54.1%), 21-25 years (31.6%), 26-30 years (3.8%), 31-35 years (6.2%),

and 36-40 years (4.3%). In total, 298 patients (80.5%) underwent orthodontic treatment with extraction, while 72 patients

(19.5%) were treated without extraction. Premolars were the most frequently extracted teeth, particularly maxillary premolars

(66.8%). Class II malocclusion was the most prevalent (75.7%), followed by Class I (14.9%) and Class III (9.5%). The study

highlights the prevalence of specific extraction needs and malocclusion types, guiding personalized orthodontic treatment

strategies. Tooth extractions, particularly of premolars, play a significant role in managing malocclusion. The gender

distribution and age demographics align with similar studies, emphasizing the importance of tailored orthodontic care.

Understanding these patterns helps in planning effective treatment strategies to achieve optimal dental alignment and

functional outcomes.
