Prevalence of impacted and supernumerary teeth in the North Indian population

Abstract

Objectives: Dental impaction is a very frequent problem. Supernumerary teeth, or hyperdontia, are the presence of additional teeth to the normal series in the either of the dentition. The presence of impacted and/or supernumerary teeth can cause various complications. The objective of the present study was to determine the prevalence of impacted and supernumerary teeth in the North Indian population. Study Design: The panoramic radiographic records of 4750 patients attending the Department of Oral Medicine and Radiology, Jodhpur Dental College General Hospital between September 2008 to December 2012 were examined for this retrospective study. The ages of the patients ranged from 8 to 72 years, with a mean of 34.6 years. Results: A total of 798 (16.8%) patients presented with 1126 impacted teeth. Impacted canines were the most prevalent (9.7%), followed by impacted premolars (4.3%). Supernumerary teeth (1.6%) and impacted molars (1.2%) were less prevalent. Among the 842 impacted teeth, the most frequently affected teeth were the canines (56.7%), followed by premolars (27.8%), and supernumerary teeth (9.3%), while the prevalence of impacted molars was quite lower (6.2%). Conclusion: The most frequently impacted teeth were maxillary canines and the mesiodens were the most common supernumerary tooth. The early diagnosis of supernumerary and impacted teeth is essential to prevent malocclusion and malalignment of permanent teeth demonstrating the importance of panoramic radiographs in their detection. Key words:Impacted, supernumerary, prevalence, canines, mesiodens.

Radiographic Analysis and Prevalence of Impacted Maxillary Canine Teeth in Children Between 8 and 16 Years

“…However it is lower than that reported by Aydin et al (2004) who found a 3.29% in a population of Turkey and found by Patil & Maheshwari (2014) which was 9.7% in India.…”

Impacted maxillary second premolars: a report of four cases

“…Such differences in prevalence rates may be due to differences in the genetic and ethnic backgrounds of the patients involved. A recent study in an Indian population indicated that the prevalence of tooth impaction was 16.8%, within the range 5.6–18.8%, as reported in earlier studies 10 11…”

Management of Complicated Crown Fracture and Associated Impacted Mesiodens- Case Report with 3yrs Follow-up

“…Mesiodens is more common in the permanent than in the primary dentition. The incidence of occurrence of mesiodens in Indian population was estimated to range from 0 to 1.4% [5]. Review done by Meighani & Pakdaman in 2010 found that the prevalence of mesiodens in various studies from 1932 to 2008 is between 0.09% and 2.05% [6].…”

“…The available evidence suggests that 80% to 90% of all supernumerary teeth are found in the maxilla and half are found in the anterior region [9]. A sex-linked pattern has also been proposed, as males are affected twice as frequently as females [5,6,9]. Mesiodens can occur individually or as multiples (mesiodens), may appear unilaterally or bilaterally, and often do not erupt [6,9].…”
