A cusp is an elevation or mound on the crown portion of the tooth making up a divisional part of the occlusal surface.
In humans, the cusp are formed in posterior teeth i.e. The molars and premolars. The cuspal arrangement in the maxilla and mandible should compensate with each other so that correct occlusion occurs or this can lead to attrition.
The first premolar has a large buccal cusp which is well formed with non functioning lingual cusp.
The second premolar has three well formed cusp i.e. One large buccal cusp and two small lingual cusps.
The maxillary first molar has four well developed functioning cusp and one supplemental cusp. The four large cusps are mesiobuccal, distobuccal, mesiolingual, distolingual. The supplemental cusp is called as tubercle of carabelli.
In maxillary second molar, the distolingual cusp is poorly developed and makes the development of the other three cusps prominent.
u people havent mentioned regarding an extra distobuccal cusp on maxillary molars….like the one found in case of mandibular molar called as paramolar cusp?????whts the mname of such cusp on maxillary molar
Cusp of Carabelli?
