Summary

The protostylid, a dental trait, appears more frequently on third molars in Slovenians. Silicone dental casts offer a more reliable method for identifying protostylid pits than alginate casts.

Area of Science:

  • Anthropological dentistry
  • Human dental morphology
  • Forensic odontology

Background:

  • The protostylid is a variable cusp found on molars.
  • Its prevalence and identification methods require further investigation.

Purpose of the Study:

  • To determine the frequency of protostylids in a Slovenian population.
  • To evaluate the reliability of dental casts for protostylid identification.
  • To compare silicone and alginate impression materials for dental casting.

Main Methods:

  • Analysis of 942 extracted lower molars for protostylid presence.
  • Creation of dental casts from alginate and silicone impressions of 32 molars.
  • Histological confirmation of protostylid pits.
  • Comparison of identification accuracy between extracted teeth and dental casts.

Main Results:

  • Higher protostylid frequency observed on third molars (51.2%).
  • Silicone casts provided more reliable protostylid pit identification than alginate casts.
  • Protostylid identification from silicone casts may exceed accuracy on extracted teeth.
  • Enamel hypoplasias can lead to misidentification without histological confirmation.

Conclusions:

  • Silicone dental casts are a reliable tool for studying protostylids.
  • Increased attention to protostylids on lower third molars will enhance data accuracy.
  • Further research on protostylid frequency and expression is valuable for anthropological and forensic studies.
