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...

BACKGROUND The associations between the length and morphological shape-related characteristics of palatal rugae have not been fully explored. OBJECTIVE We aimed to assess the possible association among various geometric configurations of the palatal rugae in an adult population. MATERIALS AND METHODS The maxillary dental casts of 217 non-growing subjects (95 males, 122 females, mean age 25....

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...

Orthopedic appliances such as palatal expanders and facemasks have been successfully used for young patients with Class III malocclusions. A modified rapid palatal expansion (RPE) appliance in conjunction with a facemask can be used for correction of transverse and sagittal discrepancies in the initial phase of treatment for these patients.

Heroin induced palatal perforation is a very infrequent complication. The authors report in this study a patient who suffered palatal perforation as a result of long time of snorting Heroin. He presented complaining of liquid passage from the oral cavity into the nasal cavities and hypernasality during speech. An immediate transparent acrylic partial obturator was constructed and fitted. It was...

Feeding a neonate with a complete cleft lip and palate is difficult pursuit due to communication between oral cavity and nasal cavity. A multidisciplinary approach is required to manage the complex problems involved in case of such neonates and their families. Present case is of a 1-day-old neonate having complete bilateral cleft lip and palate for which palatal obturator was constructed. A ste...

BACKGROUND Although a host of local soft tissue flaps have been described for the reconstruction of postoperative palatal defects, tissue-borne palatal obturators remain the most common form of rehabilitation of these defects. The palatal island flap, first applied to the reconstruction of the retromolar trigone and palatal defects, was first described by Gullane and Arena in 1977. This single-...

Talon cusp is a rare developmental extra cusp-like projection on the cingulum area of affected anterior teeth that may cause various functional and aesthetic problems. The present report describes a case of bilateral palatal talon cusps on permanent maxillary incisors and the treatment procedure to overcome the clinical problems associated with talon cusps.

A prospective longitudinal study in 75 growing cats was conducted to evaluate palatal soft-tissue expansion in cleft lip and palate surgery. In 31 cats, palatal scars were induced by simulated Langenbeck surgery at the age of 8 weeks. At the age of 14 weeks, custom-made tissue expanders were inserted in 61 animals. Tissue expansion was performed by weekly inflation in 33 cats (16 without and 17...

This study aims to determine the stability of palatal rugae before and after orthodontic treatment. 50 orthodontic cases were selected with pre- and posttreatment casts and 50 casts were randomly selected as variables. Landmarks on the palatal raphe and rugae were marked on the maxillary casts. Points were made on medial and lateral ends of first, second and third rugae. Each cast was photograp...
