Abstract
Objective: To explore the pulp cavity of age-related changes in diameter on mandibular first premolars. Method: 80 cases of age clearly and intact mandibular first premolars are taken X -ray in buccolingual and mesiodistal directions and the pulp cavity diameters are measured; then statistics pulp cavity diameter average value.Result: pulp cavity diameter decreases gradually as peopled age increases. Conclusion: The pulp cavity on mandibular first premolars of different ages shows "flat funnel-shaped" and is not conducive to the rotation of the imported equipment in root canal preparation; by measuring the pulp cavity diameter, provide reference for forensic and archaeological conjecture individual age.关键词
