Single palatal processes or homotypic paired palatal processes from 12-day mouse embryos (strain C57Bl) were grown in organ culture on Millipore filters. The epithelium along the medial edge of each palatal process became disrupted, and, by 72 hours of culture, paired palatal processes achieved mesenchymal fusion at the site of disruption. The nasal epithelium of paired palatal processes became...

Palatal rugae patterns are anatomic structures considered unique to each person. Monozygotic twins present similarities, however, Rugoscopy in particular, may contribute to their individualization for forensic purposes. The aims of this study were: to study the palatal rugae classifications of Briñón; to propose improvements to facilitate use of this method, if pertinent; and to characterize pa...

Infant mammalian feeding consists of rhythmic suck cycles and reflexive pharyngeal swallows. Although we know how oropharyngeal sensation influences the initiation and frequency of suck and swallow cycles, the role of palatal sensation is unknown. We implanted EMG electrodes into the mylohyoid muscle, a muscle active during suckling, and the thyrohyoid muscle, a muscle active during swallowing,...

OBJECTIVES The aim of this study was to assess the apical sealing ability of different core materials used with Epiphany(TM) sealer and to evaluate the effect of Resilon/Epiphany(TM) system on creating an apical mono-block seal. METHODS Fifty-five extracted human teeth were used. Forty-five were selected and randomly divided into three groups and ten teeth were used as positive and negative c...

Construction of complete denture with adequate retention is a complex procedure. Use of suction cup in a maxillary denture is one of the techniques to improve retention. Palatal Suction cup, which provides high retention by inducing negative pressure on the mucosal surface, is not being recommended because of its pathological effect on the palatal tissues leading to palatal perforation. Surgica...

The palatal mass can pose a difficult diagnostic dilemma for the clinician. In differential diagnosis of the palatal mass, dental causes must be considered because they are so common. The palatal abscess typically represents the palatally directed drainage of an infection of pulpal or periodontal origin. The palatal abscess is often observed in the premolar-molar region and presents as a compre...

Symptomatic palatal tremor is caused by a lesion in the triangle of Guillain and Mollaret and is associated with hypertrophic olivary degeneration that has multiple causes. Essential palatal tremor has no currently demonstrable cause and no accompanying physical or radiological signs. But it is probable that an organic genesis will become apparent. I suggest that some examples of palatal tremor...

The majority of maxillary defects can be rehabilitated with conventional simple obturator prosthesis. However, inadequate retention, stability and support may be associated with the use of an obturator. Precision attachments have been used to retain obturators for some time. The use of precision attachments in a dentate maxillectomy patient can yield significant functional improvement while mai...

BACKGROUND There is a lack of evidence on the relationship between prematurity and palatal abnormalities. The aim of this study was to evaluate the incidence of palatal groove, the associated factors and the persistence time in preterm infants from birth to 24 months of age. METHODS The children's data, medical history and eating habits were collected using a questionnaire answered by the leg...
