Abstract
Objective: The aim of the present study was to evaluate the demographic profile of supernumerary molar (SM) teeth in people in various regions of Turkey. Study Design: A retrospective analysis was carried out on an initial sample of 104,902 subjects drawn from the ortopantographics files from 10 clinics in 7 Turkish cities with documentation of demographic data, the presence of SM teeth, their location, eruption, morphology, and position within the arch. In one region associated pathologies and treatments were also evaluated. Results: Three hundred fifty-one SMs were detected in 288 patients, constituting 0.33% of the study subjects, with a greater frequency in females (56.4%). SMs were found more frequently in the maxilla (87.7%) than in the mandible, and distomolars (62.9%) were more common than paramolars. The SMs encountered were mostly of conical shape (45.7%), impacted (81.1%), and in a vertical position (52.1). The 33% of SM teeth were related to impacted molar teeth. Conclusion: The most common complication involving these teeth was soft tissue irritation. Demographic data from such specific extensive studies are crucial for improved diagnosis of SM teeth. Early detection allows for measures against complications and more successful therapy. Key words:Supernumerary molars, distomolar, paramolar, prevalence.
Highlights
Supernumerary teeth (ST) can be defined as any teeth or tooth substance in excess of the usual configuration of the normal number of deciduous or permanent teeth (1)
In this study we aimed to evaluate the demographic profile of supernumerary molars (SMs) in various regions of Turkey
There was no predominance according to sex for distomolars, paramolars were more prevalent in females, with a male to female ratio 1:2 (Table 2)
Summary
Supernumerary teeth (ST) can be defined as any teeth or tooth substance in excess of the usual configuration of the normal number of deciduous or permanent teeth (1). ST may erupt normally, be inverted or transverse, assume an ectopic position, or follow an abnormal path of eruption They can be diagnosed during a routine, clinical, or radiographic evaluation and sometimes are not responsible for any discernable side effects on the neighboring teeth. In addition to demographic data, SM location, eruption, morphology, position within the arch, complications related to SMs, and treatment options were evaluated. Demographic data from these studies are vital for improved diagnosis of SM as early as possible to avoid complications and ensure successful therapy. Several previous studies (8-10) have given statistics for various ST or SMs in various populations, but there was no specific extensive study considering supernumerary molar teeth
