BACKGROUND Palatal rugae are distinct to each individual and are highly specific to each individual as their fingerprints. Rugae pattern are specific to different racial groups making it convenient for population identification. Palatal rugae retain their shape throughout life and hence can be useful as an identification tool. The present study aimed at analyzing the differences in rugae patter...

have been examined with cellular markers, such as cell proliferation, cytoskeletal formation and apoptosis to understand the precise mechanism of palatal rugae morphogenesis. In particular, expression patterns of signalling molecules, Shh and Bmp4, which express in rugae and inter-rugae regions respectively, suggest that molecular interactions would govern the epithelial differentiation and pat...

=Abstract=Sprague-Dawley rat fetuses ranging from 15to 19-day of gestational age, were studied with their rugae morphogenesis a t the light microscopic level. The distribution of collagen fibers in the palatal mesenchyme was analyzed. In addition, an attempt to evaluate the role of collagen fibers in rugae development was made. The specimens were H-E stained and collagen fiber stained according...

Aim and Objectives : The present study was aimed to nd gender differences in lip prints and rugae pattern and also to correlate particular lip print and rugae pattern. Methodology 150 individuals (75 male and 75 female) were included for the study. Lip prints were taken on the glued portion of cellophane strip and was stuck on the white bond paper. The grooves present on the middle portion of ...

BACKGROUND Human identification is one of the most challenging subjects that man has been confronted with. The fingerprints and DNA comparison are the most commonly used techniques in human identification. Palatoscopy is one of the recently developing methods to identify a victim-based on the palatal rugae pattern. AIMS AND OBJECTIVES The aim of the study was to analyze the different rugae pa...

Background: Palatal rugae have been shown to be associated with racial and geographical variations and are known to be useful in sex identification. The present study aimed to assess palatal rugae patterns in a sample Iranian population and to compare the results with those from other studied populations.Methods: During summer 2017, 130 pre-orthodontic plaster casts from patients aged 17-25 yea...

Background: Palatal rugae are irregular and non-identical mucosal elevations seen on anterior third of palate. They are arranged in transverse direction on either side of Median Palatine Raphe [MPR]. Though they are the most stable anatomical structures in the oral cavity, certain conditions like orthodontic treatment contribute to some amount of variations in their pattern qualitatively. Durin...

Objective. To investigate the influence of reproduction of different thickness and palatal rugae materials on complete dentures speech using Computerized Speech Lab (CSL) (spectrogram). Materials and Methods. Three completely edentulous male patients (aged 50-60 years) were selected for reading a paragraph. Twelve upper dentures were constructed, four for each patient. The patients' speech grou...

This study investigated the morphometric changes that occur in palatal rugae during orthodontic treatment. The potential impact of these changes on the individuality of the palatal rugae patterns and on the use of palatal rugae patterns in human identification was also explored. Fifty pairs of pre- and post-orthodontic treatment dental casts were used. The palatal rugae patterns were compared b...
