However, in diastematic individuals these surfaces may not make contact but are still considered approximal. Due to the topography of approximal sites the removal of plaque by brushing may be difficult and hence a significant build-up may occur increasing the risk of plaque-related diseases such as dental caries or gingivitis , [ 1 ] [ page ...
The term posterior teeth refers to premolars and molars, as opposed to incisors and canines, which are anterior teeth. [1] [5] Proximal The surfaces of teeth that normally lie adjacent to another tooth. Proximal includes both mesial and distal, such as when referring to the proximal surfaces of teeth. [1] Quadrant
A cusp is an elevation on an occlusal surface of posterior teeth and canines. It contributes to a significant portion of the tooth's surface. Canines have one cusp. Maxillary premolars and the mandibular first premolars usually have two cusps. Mandibular second premolars frequently have three cusps--- one buccal and two lingual.
Dental caries (cavities), described as "tooth decay", is an infectious disease which damages the structures of teeth. [43] The disease can lead to pain, tooth loss, and infection. Dental caries has a long history, with evidence showing the disease was present in the Bronze, Iron, and Middle ages but also prior to the neolithic period. [44]
In the universal numbering system, one number is used to identify the tooth. The right permanent maxillary first molar is known as tooth "3", and the left permanent maxillary first molar is known as tooth "14". In the Palmer notation, a number and symbol are used to identify the tooth. The number identifies the tooth position relative to the ...
In the posterior teeth, both in upper and lower jaw, the lingual height of contour is found at the middle third of the inner surface of the tooth. The lower second premolar proposes an exception as its height of curvature in inner surface is located in the occlusal third of the inner surface. In addition, the curvature of CEJ is more pronounced ...
According to the New York Times, here's exactly how to play Strands: Find theme words to fill the board. Theme words stay highlighted in blue when found.
The shape of the developmental and supplementary grooves, on the occlusal surface, is described as being M-shaped. The mandibular first molars are the most common carious teeth and the most common teeth to undergo endodontic treatment or extraction. Up to 45% of all extracted teeth are mandibular first molars. [1]
