| Summary: | Objective: The purpose of this study was to
compare the relation of craniofacial structures
of mutation and non mutation group in class III
malocclusion of Malaysian Malay families and
their three generations.
methodology: Three generations of
Malaysian Malay families with an average age
22.50 (+/-5.30), 53.50 (+/-10.06) and 79.20
(+/-9.35) years of each generation respectively
were elected for this study. Cephalometric
radiographs of these families were taken for
further analysis. All landmarks were
positioned, determined and consequently
tracings were completed using Romexis
software (Planmeca, Finland) to accomplish
craniofacial morphology investigation. The
statistical comparisons of the mutation and
non-mutation group were directed with t test
and analysis of variance (ANOVA) was applied
to evaluate the values for three generations in
class III malocclusion among all
measurements.
Results: Current study revealed that in
mutation group, there are significant
differences in Co-Gn-B and SN-MP variables
compare to non-mutation group. However,
almost all craniofacial variables show no
significant differences among three
generations.
Conclusions: This study may suggest that in
mutation group mandible is more deviated
from cranial base and there are almost no
skeletal changes among three generations in
case of class III malocclusion. |
