Anatomical Insights: Two Case Reports on Protostylid Variants and Literature Synthesis

Area of Science:

• Dental Anthropology
• Human Anatomy
• Oral Pathology

Background:

• Protostylids are an anatomical variant of the paramolar tubercle, characterized by an extra cusp on the buccal surfaces of maxillary and mandibular bicuspids and molars.
• This rare dental trait was first documented by Dahlberg in 1950 and is significant in the field of dental anthropology.
• The presence of protostylids, though infrequent, has clinical relevance due to potential oral health complications.

Observation:

• This article presents two cases of protostylids identified during routine dental consultations.
• The cases were observed at a primary health care center in Semmencheri, Chennai.
• The study highlights the importance of recognizing this anatomical variation in clinical settings.

Findings:

• Protostylids represent an anatomical variation with potential implications for oral health.
• The presence of this extra cusp can pose a risk for developing dental caries and periodontal diseases.
• Early diagnosis and intervention are necessary for managing the associated risks.

Implications:

• Increased awareness among dental professionals regarding protostylids is essential for accurate diagnosis.
• Prompt identification allows for the implementation of targeted preventive dental care strategies.
• Understanding and managing this trait can contribute to improved patient oral hygiene and long-term dental health.
