The 2012 edition of the Dental Claim Form includes fields for diagnosis codes and instructions covering the use of the ICD-9-CM and ICD-10-CM coding systems. In addition to ICD-9-CM and ICD-10-CM there are other dental diagnostic coding systems under consideration, including SNODENT and EZCODES .
An open contact of approximately 1.5 mm shown between two posterior teeth. The shred of meat, at right, was recovered from the open contact more than 8 hours after the patient had last eaten meat, even though the patient claimed to have brushed his teeth twice since eating the meat the night before, thus exhibiting the importance of maintaining cleanliness of open contacts with an oral hygiene ...
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
The first tooth contact that occurs when the mandible closes in the terminal hinge axis position, is termed Retruded Contact Position (RCP). [13] RCP can be reproduced within 0.08mm of accuracy due to the non-elastic TMJ capsule and restriction by the capsular ligaments, thus it can be considered a ‘border movement’ in Posselt’s envelope .
Angularis nigra, Latin for 'black angle', also known as open gingival embrasures, and colloquially known as "black triangle", is the space or gap seen at the cervical embrasure, below the contact point of some teeth. The interdental papilla does not fully enclose the space, leading to an aperture between adjacent teeth. [1]
2 types of malalignment are being measured, rotation and displacement. Rotation is defined as the angle formed by the line projected through contact areas of observed tooth and the ideal arch line. Displacement is defined as both of the contact areas of the tooth are displaced in the same direction from the ideal alignment position. [8]
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 ...
Pulpal damage (tooth preparation opens dentinal tubules providing a connection between bacteria in the mouth and the pulp. Deep preparations can cause pulpal injury) Occlusal stability (prevent tilting, drifting, rotation and over-eruption of adjacent/opposing teeth) Secondary caries (around crown margins, under debonded retainer wings)
