Mandibular Lateral Incisor

Mandibular Lateral Incisor

Anatomy

The Mandibular Lateral Incisor is smaller in size compared to the central incisor. It has a single root and a sharp incisal edge. The crown is relatively symmetrical and the cingulum, or the raised, rounded area on the lingual surface of the tooth, is less developed than in the central incisor.

Development

The development of the Mandibular Lateral Incisor begins around the 14th week of embryonic life. The calcification process starts around the 3rd to 4th month of life and the tooth typically erupts into the oral cavity around the age of 7 to 8 years.

Clinical Significance

The Mandibular Lateral Incisor is often involved in dental procedures such as orthodontic treatment, root canal therapy, and extractions. It is also one of the most commonly impacted or missing teeth in the human dentition.
