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...

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...
BACKGROUND The specialization of forensic odontology is fast emerging as a branch that helps in personal identification of both living as well as dead individuals and also in crime scene investigations. Establishing a person's identity can be a challenging task in cases of road accidents or acts of terrorism or mass disaster scenario. It is an established fact that palatal rugae are unique for ...
One of the main objectives of the forensic sciences is establishing a person's identity which can be a very complex process. The analysis of the teeth, fingerprints and DNA evaluation are probably the most used techniques allowing fast and secure identification processes. Palatal rugae or transverse palatine folds are asymmetrical and irregular elevations of the mucosa located in the anterior t...
The study of identical twins can point out potential limitations in biometrics and forensic odontology. This case report presents three-dimensional (3D) palatal rugae analysis in monozygotic twins utilizing digital models obtained directly by scanning the maxillary dental arch with the iTero® intraoral digital scanner. The results show that the rugae patterns contain related but not identical f...
Palatal rugae patterns have unique characteristics and have been proposed as an alternative method to establish identity when other means, such as fingerprints and dental records, are not attainable. This study was conducted to determine the morphological characteristics of palatine rugae and to assess the existence of side asymmetry in them in Sudanese Arabs. It also assesses the possibility o...
This study was designed to investigate the prenatal development of the palatal rugae in the White Rat and to discuss the possible role played by the developing rugae in palatal shelf elevation. Extraction of embryos from twenty pregnant female rats was carried out in the 12th, 13th, 14th, 15th and 16th day of pregnancy. Four embryos from each age were decapitated and their heads were fixed and ...
Human identification is a major task undertaken in forensic sciences. Palato-rugoscopy is based on the principle that no two palates are the same. The study of palatine rugae and the study of fingerprints are sometimes complementary as they operate in similar methods based on same scientific basis. The study intends to describe the shape and gender distribution of the palatine rugae and their p...
background: forensic odontology plays important role in identification of human remains in mass disasters such as air crash, tsunami, and accidents. palatal rugae act as an ideal requisite for human identification as they are present in all victims and are resistant to changes such as aging and trauma. the study aimed to analyze differences in shape and number of palatal rugae in population fro...
