Effect of vitality on translucent dentine - a study.

Area of Science:

• Dentistry
• Forensic Odontology
• Dental Histology

Background:

• Sclerosis of dentinal tubules, a response to dental insult, leads to apical translucency.
• The mechanism of apical translucency formation is not fully understood.
• Apical translucency is utilized in forensic science for age estimation, but its comparison between vital and non-vital teeth is limited.

Purpose of the Study:

• To investigate and compare the amount and distribution of apical translucent dentin in vital versus non-vital teeth.
• To determine if tooth vitality influences the degree of apical translucency.

Main Methods:

• Seventy extracted teeth were tested for vitality and divided into vital and non-vital groups (minimum 35 each).
• Ground sections of 150µ thickness were prepared.
• Apical translucency area and length were measured using PROPLUS IMAGE ANALYSIS SOFTWARE.

Main Results:

• Significant differences (p < 0.05) in apical translucency were observed between vital and non-vital teeth.
• Non-vital teeth demonstrated a higher percentage of apical translucency than vital teeth.
• This difference was consistent across different ages.

Conclusions:

• Tooth vitality is a significant factor affecting apical translucency.
• Non-vital teeth have more apical translucency than vital teeth.
• Findings contribute to understanding dentinal changes and age estimation methods.
