2021年9月12日 · A transverse ridge crosses the occlusal surface of posterior teeth in a more or less buccolingual direction, running between the buccal and lingual cusps on a premolar (seen from an occlusal view and a proximal view in Figs. 1-25 and 1-26) or connecting the buccal and lingual cusps that are lined up across from one another on a molar (seen on a ...

Lingual foramen – The lingual foramen is a small pin-point opening in bone on the lingual aspect of the anterior mandible for the lingual nerve and arteries. The lingual foramen appears in the midline below the apices of the central incisor teeth. This dot-like radiolucency is frequently surrounded by the genial tubercle.

2015年1月5日 · The lingual surface has a cingulum that corresponds to the lingual developmental lobe, although its prominence or development differs for each type of incisor. These teeth also have a lingual fossa and marginal ridges on the lingual surface, again in differing

2015年1月3日 · Oblique ridge: It is a ridge obliquely crossing the occlusal surfaces of maxillary molars. It is usually formed by the union of triangular ridge of distobuccal cusp and distal cusp ridge of the mesiolingual cusp.

The length of the midline lingual canal (MLC), direction, and distances of the canal from the crest of the ridge, lower border of mandible, labial cortex, and lingual cortex. subjects were divided into three age groups 20–40, 40–60, and >60 years.

Which tooth would likely be a small anterior tooth that has a pointed or tapered shape? A lingual ridge is a typical landmark or characteristic found on which teeth? A small distal cusp is found on the occlusal surface of which tooth? Which premolar has numerous small supplemental grooves on the occlusal surface?

The lingual ridge extends from the cusp apex towards the cingulum, and it divides the lingual fossa into two smaller fossae - mesial and distal lingual fossae. The cingulum is very developed in canine teeth, and it makes these teeth wider buccolingually than mesiodistally.

Lingual ridge — The ridge of enamel that extends from the cingulum to the cusp tip on the lingual surface of most cuspids.

2017年10月13日 · The lingual cusp ridge extends from the cusp tip lingually to the central area of the occlusal surface. This cusp also presents four cusp ridges and four inclined planes located and named in the same manner as those of the buccal cusp.
