The mechanism of human snoring caused by vibration of the soft palate and the characteristics of the noise are investigated. The soft palate becomes unstable and vibrates violently once the inspiratory flow exceeds a critical speed. The physiological phenomenon is modeled by studying flow over a flexible plate. In determining the stability of this flow, the trailing edge conditions are crucial....

Introduction: Rugoscopy or palatoscopy is the study of palatal rugae in order to establish a person’s identity. Rugae are protected from trauma as they are insulated from heat by tongue and buccal pad of fat, unlike fingerprints or lip prints that can get destroyed. Aims and objectives: This study was aimed to compare the rugae patterns in males and females of different age groups of Lucknow ci...

Fetuses were obtained from CD-1 mice at a time estimated to be 12 h prior to vivo secondary palate closure. One of the palatal shelves of each partially dissected fetal head was lesioned in one of five ways, the other left intact to serve as control. Single transverse cuts extending the width of the shelf were made at one of three positions along the longitudinal axis of the shelf: one-third, o...

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...

We thank Dr. Ozdogan and colleagues for their comments regarding our article on the management of palatal myoclonus with botulinum toxin. As we state in the article, weakening of the palatal musculature to treat the symptoms of a clicking tinnitus, awareness of palatal movements with or without rhinolalia, or both can potentially lead to velopharyngeal incompetence, rhinophonia, dysphagia, and ...

Forensic dentistry is the examination and evaluation dental evidence which will be then presented in the interest justice. The palatal rugae are generally transverse ridges situated in the anterior part the palatine mucosa. Palatal rugae are resistant to chemical aggression, thermal effects and decomposition changes because internal position in the head. They are widely used in edentulous patie...

Articulatory token-to-token variability not only depends on linguistic aspects like the phoneme inventory of a given language but also on speaker specific morphological and motor constraints. As has been noted previously (Perkell (1997), Mooshammer et al. (2004)) , speakers with coronally high ”domeshaped” palates exhibit more articulatory variability than speakers with coronally low ”flat” pal...

Background and Objectives : It has been suggested previously that increased width of midfacial structure is associated with the development of palatal clefting. One of the most important heritable characteristics predisposing towards the development of orofacial clefting in an embryo is craniofacial morphology. The aim of the study was to compare nasomaxillary width of parents of children with ...

This paper describes the contribution to speech perception given by animations of intra-oral articulations. 18 subjects were asked to identify the words in acoustically degraded sentences in three different presentation modes: acoustic signal only, audiovisual with a front view of a synthetic face and an audiovisual with both front face view and a side view, where tongue movements were visible ...

This article evaluates intertalker variance of oral area, logarithm of the oral area, tongue height, and formant frequencies as a function of vowel category. The data consist of coronal magnetic resonance imaging (MRI) sequences and acoustic recordings of 5 talkers, each producing 11 different vowels. Tongue height (left, right, and midsagittal), palate height, and oral area were measured in 3 ...
