Double mandible coronoid process: a very unusual feature.

Purpose: The double coronoid process (DCP) is a very unusual feature in patient. The literature, which briefly describes just only one case. Being this a very unusual feature, the aim of the paper is to describe the finding, discuss the anatomic, radiological, and clinical characteristics of a DCP.

Prevalence of retromolar canal and its association with mandibular molars: study in CBCT.

Objective: Investigate the presence and characteristics of the retromolar canal and association with mandibular molars using cone-beam computed tomography (CBCT).

Study Design: CBCT images of 200 consecutive patients were analyzed using the Anatomage Invivo 5 software. Retromolar canal present evaluated the type of trajectory, buccal or lingual location, uni or bilateral, origin and final diameters.

Cleft lip and palate cause large variations in size and location of the posterior superior alveolar canal.

Objective: The aim of this study was to evaluate the posterior superior alveolar canal (PSAC) in patients with cleft lip and palate (CLP) as compared to patients with no cleft lip and palate (NC) using cone-beam computed tomography (CBCT).

Materials And Methods: This was a retrospective multicenter study based on two steps: (1) evaluating intra- and inter-calibration and (2) detecting the presence or absence of PSAC and its location, diameter, and anastomosis with anterior superior alveolar canal.

Results: A total of 300 patients were selected for the study, out of which 150 were categorized as CLP (75 men, 75 women; mean age: 29.
