Half of them are located on the maxilla (maxillary incisors), while the remaining four are situated on the mandible (mandibular incisors). According to the universal dental numbering system, they are numbered 7 through 10 and 23 through 26, respectively.

2015年3月3日 · The mandibular central incisor is the narrowest tooth in the dentition. It has sharp mesioincisal and distoincisal angles and a shallow lingual fossa. The root is typically single and straight, tapering to a relatively sharp apex. The crown is wider labiolingually than mesiodistally.

2021年6月27日 · The mandibular central incisor is among the few teeth that show very few developmental grooves and lines. The lingual surface of the tooth also shows a symmetrical outline. The crown and the root of the tooth taper towards the lingual aspect therefore part of the proximal surfaces of the crown and root are visible from the lingual aspect.

Mandibular central incisors – Permanent mandibular central incisors is the most symmetrical tooth in the dental arch and has a very smooth lingual surface with barely noticeable marginal ridges and fossa.

The mandibular central incisor is the most symmetrical tooth in the oral cavity. This tooth is fan-shaped with sharp incisal angles. The mamelons of this tooth usually wear off quickly, and they are only present right after the tooth erupts.
