Summary
Asian teeth are shorter than Caucasian teeth, with a mean difference of 1.2 mm in canal length. This study compared root canal lengths in Asian and Caucasian patients to identify racial differences.
Area of Science:
- Endodontics
- Dental Anatomy
- Comparative Anthropology
Background:
- Root canal length is a critical factor in endodontic treatment success.
- Previous research has not conclusively determined racial differences in root canal anatomy.
Purpose of the Study:
- To investigate and quantify potential racial differences in root canal length between Asian and Caucasian populations.
- To compare endodontic working lengths in Asian and Caucasian patients.
Main Methods:
- A retrospective study comparing 515 Asian patients (Korea) and 324 Caucasian patients (US).
- Working lengths were measured using an electronic apex locator and verified with radiography.
- Statistical analysis included Student's t-test and Mann-Whitney test.
Main Results:
- A mean difference of 1.2 mm in canal length was observed between Asian and Caucasian teeth (range: 0-2.5 mm).
- The greatest differences were noted in specific canals, including the distobuccal canal of maxillary first molars (2.5 mm).
Conclusions:
- Tooth canal lengths in the studied Asian population were significantly shorter than in the Caucasian population.
- These findings suggest anatomical variations in root canal length based on ethnicity, impacting endodontic procedures.
