3.10: CUSP OF CARABELLI
(S W Flanagan, 7-1) 1; Licklighter (4-1) 2; Yeats Mardy (3-1) 3.
The prepared dental plaster casts were examined for morphological variations such as shoveling, bushman canine, distal accessory ridge and cusp of Carabelli. These traits were analyzed through Arizona state university tooth morphology system.
In results the cusp of Carabelli exhibited maximum expression in Swati group while in Swati and Gujars more shoveling was observed as compared to Jadoons however the Bushmen canine was totally absent in these groups.
The objective of study was to examine how much dental morphological traits e.g shoveling, double shoveling, distal accessory ridge, Bushmen canine and cusp of Carabelli are present in each ethnic group (Gujar, Jadoon and Swati) and their comparison among these ethnic groups.
(3) It may occur alone or in association with other dental anomalies like bifid cingula, exaggerated cusp of carabelli
, dens invagintus and in particular shovel shaped maxillary incisors.
These groups were characterized by a high frequency of cusp expression of the cusp of Carabelli, the X cusp pattern and the + cusp pattern.
This occurred in such a way that a group of Mestizos in the city of Cali was characterized in a simplification of the dental morphology as having a low frequency of the cusp of Carabelli (this trait was expressed ambiguously in their fossa forms - characteristic of sinodonts - and cuspids of medium size - a characteristic of Caucasoids), a reduced hypocone (a property of Western Caucasoid groups) and the high frequency of the point P of the protostylid (an exclusive feature of Amerindian populations) (4).
Talon cusp can be found in isolation or in association with other dental anomalies such as peg-shaped lateral incisors, shovel-shaped incisors, bifid cingulum, unerupted canines and the large cusp of Carabelli
, dens invagi-natus, supernumeraries and complex odon-tomas (2, 23, 26).
The aim of this study was to determine the prevalence of cusp of carabelli in permanent teeth in a sample from the population of Khyber Pakhtunkhwa.
Key words: Cusp of Carabelli, Unilateralism, Khyber Pakhtunkhwa
The cusp of carabelli is a nonfunctioning mini cusp or tubercle or groove or furrow that occurs on the mesiopalatal cusp at mesiopalatal line angle in maxillary first permanent molar but does not occur on maxillary second deciduous molar.
Caucasians commonly have cusp of Carabelli
which is an accessory cusp found on the mesio-lingual cusp of maxillary first molar.
