Toothbrush (10) for cleaning mesial and / or distal tooth surfaces, comprising a brush head (11, 18) for receiving cleaning bristles (14) and a brush handle (12, 19) for handling them. The brush head (11, 18) has an angled portion (13a, 13b) relative to the brush handle (12, 19...
Each tooth has five surfaces: occlusal, mesial, distal, lingual, and facial or buccal. STRUCTURE OF A TOOTH (longitudinal section); SEE: dentitionEvery human has two complete sets of teeth during his or her life. The 20 primary teeth are the first set of teeth to develop. They exfoliate...
The enamel contour extends on the buccal and lingual surfaces 2–4 mm more towards the root than on the mesial and distal surfaces. Also, enamel on the buccal and lingual surfaces can occur up to 2 years after initial root formation begins on the approximal surfaces (Liversidge et al., ...
More distal surfaces of the first permanent molars were decayed than adjacent mesial surfaces of the second molars. The appearance of dental caries on adjacent premolar surfaces was related to the order of eruption; the surface that had erupted first was likely to be decayed first. Reports from ...
In descriptive statistics regarding patient preparation experience, the averages of the preparation angles taken according to the tooth surfaces of the 4th and 5th Grades are; The averages of the mesial, distal and buccal surfaces are close to each other, but only on the palatal surfaces, there...

Each tooth has five surfaces: occlusal, mesial, distal, lingual, and facial or buccal. See: illustration; dentition Everyone has two complete sets of teeth during his life. The 20 primary teeth are the first set of teeth a person develops. They exfoliate by age 14 and are replaced by the...
Also, the mesial and distal surfaces of the pulp chamber and canal can usually be separated from the borders of the carious lesion. However, with internal root resorption, the image of the resorption cannot be separated from the pulp chamber or canal by altering the horizontal angulation of ...
The amount of orthodontic tooth movement was assessed by using a metal feeler gauge with the precision of 0.01 mm, between mesial surface of the second premolars and distal surfaces of the first premolars. The statistical package of SPSS (Kolmogorov-Smirnov and ANOVA test) was used for ...
D. A rare mandibular first premolar with a mesial and distal root. Description A very unusual maxillary first premolar with three roots (two buccal and one lingual) similar to the roots of a maxillary molar is seen in Figure 11-33. There have also been a number of reports of bifurcated...
