Missing and Impacted Teeth in Orthodontic Patients of Lucknow Population: A Case Report

This article is a retrospective study along with a case report, which examined the occurrence of missing and impacted permanent teeth in patients of Saraswati Dental College Lucknow over a period of one year. A total of 300 (165 male, 135 female) consecutive patients who presented for treatment in the Department of Orthodontics and Dentofacial Orthopedics were considered for this research; 37 cases had either missing or impacted teeth out of which 19 cases presented with one to two congenitally missing teeth, 2 of the cases had three to five missing teeth and 18 presented with one or more impacted teeth. No case was seen with both congenitally missing and impacted teeth. The case analyses focused on the type and number of missing or impacted teeth. The following teeth were most frequently missing: mandibular 3rd molars (2%), maxillary 3rd molars (1.3%), mandibular incisors (1.3%), maxillary laterals (1%), maxillary premolars (0.33%), mandibular premolars (0.33%). In the maxillary arch there were 15 cases of impacted canines (5%) of which 2 cases were bilaterally impacted maxillary canines (0.66%). Only one case presented with missing maxillary canine. In the mandibular arch there were 2 cases of unilateral mandibular impacted canines (0.66%). There was only one case with an impacted mandibular central incisor. The high prevalence, severe degree of dental agenesis and impaction of permanent teeth found in these patients reflects an interdisciplinary treatment need for these patients.
