Summary

Supernumerary molars are extra teeth, most commonly found in the upper jaw and often impacted. This study found no significant difference in frequency between sexes, aiding in understanding these dental anomalies.

Area of Science:

  • Dentistry
  • Oral and Maxillofacial Surgery
  • Developmental Biology

Background:

  • Supernumerary teeth, particularly molars, represent a deviation from typical dental development.
  • Understanding their etiology, classification, and prevalence is crucial for effective clinical management.
  • Early detection and appropriate treatment strategies are essential for preventing complications.

Observation:

  • This review synthesizes current literature on supernumerary molars, including their causes, frequency, and classification.
  • A statistical analysis of 113 cases (8 from the University of Athens, 105 from literature) was performed.
  • Key characteristics examined included sexual dimorphism, positional distribution, impaction status, and bilateral occurrence.

Findings:

  • Supernumerary molars predominantly occur in the maxilla (79.7%) and are frequently impacted (88.7%).
  • Bilateral presence was noted in 23.9% of cases.
  • The frequency of supernumerary molars did not show a significant difference between sexes.

Implications:

  • Findings highlight the high prevalence of maxillary and impacted supernumerary molars, informing diagnostic approaches.
  • The lack of sexual dimorphism suggests etiological factors are not sex-linked.
  • This data aids clinicians in prognosis, treatment planning, and early detection of supernumerary molars.
