A cusp was considered as a "pronounced elevation on the
occlusal surface of a tooth terminating in a conical, rounded or flat surface".
In the present case, the enlarged gingival tissue partially covered the
occlusal surface of the molars, getting traumatized during mastication and causing pain.
Dens evaginatus (DE) is an odontogenic developmental anomaly defined as a supernumerary tubercular structure or supplemental solid elevation on the crown surface, extending away from the
occlusal surface of the affected tooth (Fig.
The integration of optical impressions allows the
occlusal surface to be visualized precisely, thus optimizing planning for the access cavity and the exact determination of the working lengths.
Dental caries often initiates at the fissures in the
occlusal surface of the tooth.
The apical button is oval, large and occupies almost the entire
occlusal surface. This tooth is similar to the teeth of Phoebodus aff.
Therefore, the purpose of this study is to evaluate the chemical changes produced by sodium fluoride (NaF), hydroxyapatite-NaF-xylitol (HA-NaF-X), Er:YAG laser irradiation (L), and combined treatments on the
occlusal surface of permanent unerupted third molars.
This is aimed at achieving achieve an overall reduction in the height of the
occlusal surface of at least 2 mm in the axial direction and to get a cervical margin or "cervical sidewalk" in the form of a butt joint.
Many factors can lead to occlusal disharmony such as: tooth loss (Miehe et al., 1999; Benigno et al., 2001; Bazan et al., 2008); premature contact in dental occlusion (Bakke M.,1993); use of orthodontic braces and dentures (Cvetko et al., 2012) wear and abrasion of
occlusal surface of teeth (Bani et al.,1999; Santiwong et al., 2002).
There is abundant cement on the
occlusal surface of the premolars.
