During fusion of the mammalian secondary palate, it has been suggested that palatal medial edge epithelial (MEE) cells disappear by means of apoptosis, epithelial-mesenchymal transformation (EMT) and epithelial cell migration. However, it is widely believed that MEE cells never differentiate unless palatal shelves make contact and the midline epithelial seam is formed. In order to clarify the p...

Palatogenesis is directed by epithelial-mesenchymal interactions and results partly from remodeling of the extracellular matrix (ECM) of the palatal shelves. Here, we assessed heparanase distribution in developing mouse palates. No heparanase was observed in the vertically oriented palatal shelves in early stages of palate formation. As palate formation progressed, the palatal shelves were reor...

AIM The purpose of this prospective cohort study was to assess the survival and success rates of palatal implants. MATERIAL AND METHODS Seventy patients (56 female, 14 male; age 25-6 +/- 10-8 years) receiving Orthosystem (Straumann AG, Basel, Switzerland) palatal implants from March 1999 to November 2006 were included. The indication was established according to the required anchorage for ort...

Endodontic treatment may sometimes fail because morphological features of the tooth adversely affect the treatment protocol. Maxillary second molars are recognized as usually having a single palatal root with a single palatal canal. The incidence of second palatal root in the maxillary second molar is very rare. Two cases are presented in this paper describing the endodontic management of a fou...

Oral mucormycosis is a fungal infection observed mainly in elderly immunocompromised patients. In rare instances, the disease occurs in healthy individuals and those patients that are below preschool age. Although this condition mainly involves the maxilla, it may also manifest in any part of the oral cavity based on the source of infection. Mucormycosis of the maxilla spreads rapidly, leading ...

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...

The cause of objective tinnitus provoked by palatal and middle-ear myoclonus may be identified by magnetic resonance imaging of the central nervous system in the Guilliain-Mollaret triangle or it may be idiopathic. The idiopathic cases are rare. From the literature, one can perceive the following unanswered questions: (1) Are palatal and middle-ear myoclonus different entities or do they usuall...

OBJECTIVE To (1) evaluate the stability of palatal rugae as landmarks for superimposition of dental casts and (2) establish a three-dimensional superimposition method of maxillary dental casts for analyzing orthodontic tooth movement. MATERIALS AND METHODS The sample consisted of dental casts obtained from 10 patients treated with extraction of bilateral maxillary first premolars and placemen...

Introduction Variations in the root and canal morphology are a common occurrence. The clinician should have a thorough knowledge of dental anatomy and its variations in order to achieve successful and predictable outcome with root canal treatment. Maxillary first permanent molars are generally considered to be three rooted, one palatal and two buccal. The additional root canal, if present, is t...
