To measure and compare the intraoral pH and temperature of individuals during sleep with and without mouth breathing. Ten healthy participants [mean age = 25·8 (± 4·3)] wore a custom-made appliance fitted with a pH probe and thermocouple for two sets of 48 h. Continuous pH and temperature measurements were taken from the palatal aspect of the upper central incisors. To simulate mouth breathing ...

Thirty-eight specimens of free-ranging Podocnemis expansa (Amazon turtle) and 22 of P. unifilis (Tracajá) were screened for yeast isolation from surface (plastron, skin, and nails), eye, and mouth cavity. A hundred and eighteen yeast isolates belonging to 39 species were obtained. Debaryomyces hansenii, Candida galli, C. sake, and Rhodotorula mucilaginosa were the most frequent species isolated...

Aim: In recent years, the number of patients complaining of symptoms of oral discomfort such as dry mouth, tongue pain, and burning sensation of the mouth has been increasing. This study aimed to determine whether denture treatment improved oral discomfort accompanying dry and sticky sensations. Methods: Forty-eight partial and/or complete denture wearers complaining of oral discomfort were rec...

PURPOSE Comparison of quality of life (QoL) and side effects in a randomized trial for early hyperbaric oxygen therapy (HBOT) after radiotherapy (RT). METHODS AND MATERIALS From 2006, 19 patients with tumor originating from the tonsillar fossa and/or soft palate (15), base of tongue (1), and nasopharynx (3) were randomized to receive HBOT or not. HBOT consisted of 30 sessions at 2.5 ATA (15 m...

myiasis is a rare disease caused by infestation of tissue by larvae of flies. oral myiasis is still “rare” and “unique” owing to the fact that oral cavity rarely provides the necessary habitat for a larval lifecycle. herein, we present a case of extensive gingival myiasis in a 12-year-old mentally retarded, epileptic child as well as a literature review.

Ligand-gated ion channel receptors mediate neuronal inhibition or excitation depending on their ion charge selectivity. An investigation into the determinants of ion charge selectivity of the anion-selective alpha1 homomeric glycine receptor (alpha1 glycine receptor [GlyR]) was undertaken using point mutations to residues lining the extra- and intracellular ends of the ion channel. Five mutant ...

OBJECTIVE To compare patients with systemic sclerosis (SSc) recruited from a patient association or a tertiary care setting. METHODS We evaluated 248 SSc patients attending 4 annual meetings of a patient association between 2004 and 2007 (177) or during hospitalization (71). health-related quality of life (HRQoL) was assessed by the SF-36, global disability by the health assessment questionna...

Salivary dysfunction, such as reduced salivary flow and an altered composition, is caused by several diseases, medical conditions, medications. The purpose of the present study was to clarify relationship between hypertension morphological changes in submandibular glands. An epidemiological conducted elucidate dry mouth. effects on intima thickness arteries glands were histopathologically inves...

BACKGROUND Human lateralized behaviors relate to the asymmetric development of the brain. Research of the prenatal origins of laterality is equivocal with some studies suggesting that fetuses exhibit lateralized behavior and other not finding such laterality. Given that by around 22weeks of gestation the left cerebral hemisphere compared to the right is significantly larger in both male and fem...

OBJECTIVES The aim of this study was to evaluate the effects of 3 commercially available mouth rinses on the color stability of 4 different resin-based composite restorative materials. METHODS Forty disc-shaped specimens (10x2 mm) were prepared from each of the following materials: A nanofill composite Filtek Supreme XT (3M/Espe, St. Paul, MN, USA); a packable low-shrinkage composite, AeliteL...
