Abstract

Introduction: Extraction of mandibular incisor is gaining importance while deciding the extraction pattern in cases with a stable Class I occlusion with mild crowding in the lower arch. Other considerations for single incisor extraction also appear when planning a case for orthodontic treatment. Hence, this study was conducted to determine the frequency of reasons most commonly seen in single incisor extraction cases reporting to Islamabad Dental Hospital.

Material and Methods: This descriptive retrospective cross-sectional study was conducted at The Department of Orthodontics, Islamabad Dental Hospital. Data of 92 patients out of 1100 cases, was collected from patient record files for demographic variables (Age, Gender), reasons of mandibular incisor extraction such as crowding, and periodontally compromised incisors before or during treatment and reduced overjet with residual premolar extraction spaces to be closed. 

Results: Crowding was the  most frequent  reason for mandibular incisor extraction (67%), followed by reduced overjet during treatment (16%), periodontally compromised incisors before (12%) and during (4%) treatment.

Conclusions: Extractions of mandibular incisor were done as a result of a number of reasons, the most important being crowding in the lower arch. Loss of overjet to close the residual space while retracting maxuillary incisors was another important factor seen followed by presence of periodontally compromised incisors.
