Developmental stages in permanent porcine enamel.

Area of Science:

• Comparative dental anatomy
• Bio-mineralization processes
• Animal science

Background:

• Tooth enamel formation exhibits distinct stages across species.
• Understanding these stages aids in age determination and studying developmental processes.
• Pig models offer insights into mammalian tooth development.

Purpose of the Study:

• To characterize the developmental stages of permanent teeth in Danish Landrace pigs.
• To correlate visible enamel zones with chemical composition changes.
• To establish a timeline for enamel development in this specific pig breed.

Main Methods:

• Procurement of developing permanent teeth from Danish Landrace pigs of various ages.
• Macroscopic examination of enamel surfaces to identify distinct zones.
• Analysis of chemical composition changes corresponding to identified enamel zones.

Main Results:

• Visibly distinct enamel zones were identified on developing pig teeth.
• These zones corresponded to previously reported chemical composition changes in other species.
• The timing, progression rate, and duration of each developmental stage were determined for different tooth types.

Conclusions:

• The study successfully mapped developmental enamel zones in pig teeth.
• These zones serve as indicators of chemical composition changes during tooth development.
• The established timeline provides a valuable reference for pig dental development and age estimation.
