PALATAL dysfunction, the term which describes both intermittent dorsal displacement of the soft palate and palatal instability, is one of the most commonly identified causes of upper airway obstruction in horses (Barakzai and Hawkes 2010). The reported prevalence of palatal dysfunction ranges from 10 to 20 per cent in young racehorses (Pollock and others 2009, Ducharme 2012). Dynamic endoscopic...
We have identified a role for two evolutionarily related, secreted metalloproteases of the ADAMTS family, ADAMTS20 and ADAMTS9, in palatogenesis. Adamts20 mutations cause the mouse white-spotting mutant belted (bt), whereas Adamts9 is essential for survival beyond 7.5 days gestation (E7.5). Functional overlap of Adamts9 with Adamts20 was identified using Adamts9(+/-);bt/bt mice, which have a fu...
Thorough knowledge of root canal morphology is essential for the endodontic therapy. There are rare variations in canal number and configuration in maxillary molars, which could affect treatment outcome. This paper presents the endodontic management of a maxillary first molar with two palatal canals in one root (Vertucci type IV) and a single buccal canal. In this paper cone-beam computed tomog...
BACKGROUND Maxillary defects predispose patients to different undesirable effects. The aim of this study was to assess the quality of life (QoL) of patients with maxillary defects (acquired/congenital) wearing obturators. METHODS The study comprised 30 patients aged between 16 and 78 years. Interviews were conducted to collect information pertaining to patients; sociodemographic, self-reporte...
Maxillary obturator prostheses with hollow metal obturators can be made of titanium to reduce weight. To prevent perforation of the hollow obturator during modifications, the obturator is slightly undersized and covered with a replaceable cap. This cap is made of a soft copolymer to facilitate uncomplicated modifications in the resection area and to improve function.
Background and purpose: Transverse problems in the maxilla (high arched- narrow hard plates) can cause respiratory disorders. Palatal expansion can be helpful in this way. The present study aimed at evaluating the effect of bone borne expansion and tooth borne palatal expansion on airway volume. Materials and methods: A review study was performed by search in Google Scholar, Scopus, PubMed, Em...
BACKGROUND Palatal tremor is characterized by rhythmic movements of the soft palate and can be essential or symptomatic. Some patients can have palatal movements as a special skill or due to palatal tics. Psychogenic palatal tremor is recognized but rarely reported in the literature. METHODS We retrospectively evaluated all patients with palatal tremor seen in our center over a period of 10 y...
several appliances have been used for palatal expansion for treatment of posterior cross bite. the purpose of this study was to evaluate the stress induced in the apical and crestal alveolar bone and the pattern of tooth displacement following expansion via removable expansion plates or fixed-banded palatal expander using the finite element method (fem) analysis.two 3d fem models were designed ...
