Identification of individuals can be difficult in cases like accidents, or in mass disaster conditions. The oral cavity plays a significant role in identification of victims because it comprises of unique anatomy of dentition. However in certain cases, if teeth are lost due reasons like caries, periodontal problems. Human palatal rugae have been suggested as an alternative method for identifica...

Proper patterning and growth of oral structures including teeth, tongue, and palate rely on epithelial-mesenchymal interactions involving coordinated regulation of signal transduction. Understanding molecular mechanisms underpinning oral-facial development will provide novel insights into the etiology of common congenital defects such as cleft palate. In this study, we report that ablating Wnt ...

Aims: The aim of this study is to evaluate the rugae pattern changes (rugae number, length, shape, direction, and unification) in completely edentulous patients treated with complete denture. Materials Methods: A total 100 subjects were selected for study. experimental group comprised 60 participants (30 males 30 females) who had undergone denture treatment control 40 (20 20 dentulous fixed par...

It is a well known fact that with changing times, an increase in the number of natural disasters, crimes and fatalities have taken place. In such a challenging time, identification of human remains is an issue which is the call of the hour and is a grave responsibility as well [1]. Teeth are highly resistant to fire, decomposition and other extreme conditions and so they are vital in forensic i...

The most challenging situations in Forensic Odonto-Stomatology are mass disasters, where the forensic dentist is usually confronted with charred human remains or heavily decomposed or fragmented bodies. This article determines the extent of preservation of palatal rugae for use as an alternative identification tool in such situations, using a study group comprising burn victims and cadavers sim...

Speech is imperative for human communication. Therefore, phonetics must be considered , along with mechanics and esthetics as the integral factors in contributing to the success of a dental prothesis . Palatal rugae contours have a very important role in phonetics, by production of linguopalatal sounds that involves the contact between tongue and palate. By customizing palatal contours of a max...

It is widely acknowledged that in some forensic situations there are limitations to identification of the deceased by fingerprints, DNA and dental records. Palatal rugae pattern of an individual may be considered as a useful adjunct for sex determination for identification purposes. The aim of this study was to identify and compare the rugae pattern in Indian males and females, as an additional...

JCO/FEBRUARY 2004 H retainers with Adams clasps or labial wires crossing the occlusion can create interferences that may lead to bruxism or disc displacement1-3 (Fig. 1). On the other hand, if a wraparound retainer is fabricated without crossover clasps, it is difficult to adapt the round wire closely enough to the anterior dentition to provide adequate mechanical retention, especially in patie...

rugae), rat (8) and golden hamster (7). We showed that palatal growth rate, spacing and addition rate in mouse/rat were remarkably similar (with respect to the embryo size difference), and that increase to 9 rugae in mouse is achieved by postponing the end of the addition process (hypermorphosis). Such a heterochronic shift may be typical of 1 variations observed among muroid rodents. In contra...
