Morphologic observation on root canal of mandibular incisors / 实用口腔医学杂志

ABSTRACT

medial distal wall. The root canal length of central and lateral incisors were (12.96?6.46) mm and (11.47?6.32) mm respectively. The double root canal was found in 35.9 % of central incisors and in 27.5% of lateral incisors. Most mandibular incisors with long concavity had single root canal. Conclusion: The root canal wall of mandibular incisors was thinner in medial and distal wall than in lingual and labial wall. Mandibular incisors have higher rate in double root canal and the long concavity is not significantly related with number of root canal.
