Abstract :
Palatine rugae are anatomical folds
or wrinkles of irregular fibrous connective tissue located
on the anterior third of the palate behind the incisive
papilla. These rugae patterns have been widely studied
for various purposes, mainly in the fields of
anthropology, genetics, orthodontics, prosthodontics and
forensic science.
AIM: The study aims to assess the palatine rugae
stability as a landmark for analysis of orthodontic
treatment changes.
OBJECTIVES: This study was designed to investigate
the stability of palatine rugae before and after
orthodontic treatment and to explore the potential of the
palatine rugae area to be used as an adjunctive aid for
superimposition in cast analysis of orthodontic treatment
changes.
MATERIALS & METHODS: The pre and post-dental
casts of 50 orthodontically treated adult patients were
selected from the Department of Orthodontics,
Tamilnadu Government Dental College and Hospital. All
patients were indicated to have symmetrical extraction
of the maxillary first premolars followed by retraction of
the anterior teeth& space closure.All casts were analyzed
and measurements done. Comparing the pre and post
orthodontic treatment position of the rugae points
transversely, antero-posteriorly and in relation to the
median palatal plane.
RESULTS: Findings concludes that the most stable
rugae points were the points of the third rugae and this
may be due to their presence away from the extraction
position. Thus, they were the least affected by the distal
retraction of the anterior teeth. Hence, it could be used
as reference points for cast superimposition.
CONCLUSION: Palatine rugae showed stability
following orthodontic treatment and tooth movement
which presented no statistically significant effect on the
position of the palatine rugae area. Hence,it could be
used for cast analysis and superimposition.
DISCUSSION: In the present study, the rugae points in
all the measurements in relation to the median palatine
raphe revealed stability except for a slight decrease in
the values of the right second rugae which was
statistically non-significant. From these findings and the
whole results, it was concluded that the most stable
rugae points were the points of the third rugae and this
may be due to their presence away from the extraction
position.
