| Summary: | Palatal rugae refer to the ridges on the anterior part of the palatal
mucosa, each side of the median palatal raphe and behind the
incisive papilla. Various studies on different populations have
reported unique rugal patterns within each population.
Aim: To study, analyse and report the significant palatal rugae
patterns among West Godavari District population and compare
with the patterns reported in the literature, which can aid as an
additional method of identification in cases of crime or mass
disasters.
Material and Methods: Pre–orthodontic casts of 100 samples
(50 males and 50 females) were selected. The method of
identification of the rugae pattern used was that of Thomas
et al (1983) which includes the number, shape and unification
patterns of rugae. The different types of rugae between males
and females were statistically analyzed and compared with
other population studies in the literature.
Results: A statistically insignificant (p>0.05) higher mean primary
rugae scores was found in males (7.48±2.45) while secondary
(3.38±2.02) and tertiary (2.56±1.84) rugae were more among
females. Both genders showed predominance in wavy (males
= 4.82±1.91 and females = 4.74±1.98) type of distribution.
Commonly observed pattern in the mode of unification was
converging (58%) in males and diverging pattern (62%) among
femaleswhich was statistically significant (p=0.04).
Conclusions: The findings showed a specific rugae pattern in
this group when compared to other populations reported in the
literature. Palatal rugae patterns are definitely associated with
regional variation and can aid as an additional tool in forensic
identification procedures. |
