| Summary: | Background. Indonesia is a multi-ethnic country. The fusion between Mongoloid
and Austromelanesid produced Proto Melayu and Deutro Melayu race. Tooth
morphology has been known to show variation form one ethnic group to another.
This has generally, been ascribed to genetic influence and some environmental
factors. One such morphological characteristics which has warranted a lot of
investigations in different ethnic groups of the world is the trait of Carabelli and
shovel incisive. A literature review on this trait suggests an ethnic variation. Study
about tooth morphology is still rare in Indonesia. To authors’ knowledge, no
study has been carried out on the prevalence of this trait in Java ethnic.
Purpose. To determine the prevalence of Carabelli cusp and shovel incisive in
Java ethnic.
Method. This study had been done through observation at 50 alginate
impressions for maxillary arch in Java ethnic student of dentistry at UNAIR class
of 2010,2011, and 2012.
Results. Percentage of Carabelli cusp in the first molars is 46% and percentage
of shovel incisive is 86%. The type of Carabelli cusp with the highest percentage
is type V (Absent type)(54%) and the lowest is type I (Pronounced tubercle type)
(4%). The type of shovel shape incisive with the highest percentage is score 1 type
(42%) and the lowest percentage is score 3 type skor 3 (10%).
Conclusion. The percentage of sample that don’t have the Carabelli cusp is
higher than sample that have Carabelli cusp.The highest percentage of Carabelli
cusp’s type in the first molars is type V (Absent) and the lowest percentage is type
I (Pronounced tubercle). The percentage of sample that don’t have shovel in
upper first incisive is lower than sample that have shovel incisive. The highest
percentage of shovel shape incisive type is score I type and the lowest percentage
is score 3 type. |
