Central CO(2) chemosensitivity is crucial for all air-breathing vertebrates and raises the question of its role in ventilatory rhythmogenesis. In this study, neurograms of ventilatory motor outputs recorded in facial nerve of premetamorphic and postmetamorphic tadpole isolated brainstems, under normo- and hypercapnia, are investigated using Continuous Wavelet Transform spectral analysis for buc...

OBJECTIVE This study was carried out to evaluate the effects of a single pre-operative sub-mucosal injection of dexamethasone after third molar surgery to see the effects on post-operative discomfort. METHODS This study was a prospective, double-blind, randomized, clinical trial. The subjects were forty patients who underwent surgical removal of the mandibular impacted third molar under local...

OBJECTIVE Rapid analgesic onset opioids, particularly fentanyl buccal tablet, is preferable for managing breakthrough pain. The efficacy and safety of fentanyl buccal tablet and its association with around-the-clock opioids needs to be explored with an option of dose adjustments, more closely reflecting administration in clinical practice. The aim of the study was to assess the safety and effic...

Rhythmic activity that is distributed to the brain and buccal ganglia and which underlies several types of behaviour, can be evoked from isolated nervous systems of Pleurobranchaea californica by tonic nerve stimulation. The experiments presented here were designed to test whether this rhythmic activity is produced by independent neuronal oscillators located in each ganglion or whether the rhyt...

Collection and analysis of DNA, most commonly from blood or buccal cells, is becoming more common in epidemiologic studies. Buccal samples, which are painless to take and relatively easily collected, are often the preferred source. There are several buccal cell collection methods: swabs, brushes, mouthwash, and treated cards, such as FTA or IsoCode cards. Few studies have systematically compare...

The study focuses on the assessment of chromosomal damage associated with folate and vitamin B12 deficiency, and with cigarette smoking in a tissue directly exposed to cigarette smoke (buccal mucosa) while controlling for potential confounding factors. A cross-sectional study was carried out among 39 current smokers (CSs) and 60 noncurrent smokers (NCSs). Buccal mucosal cells, saliva, and blood...

OBJECTIVES The primary goal of prosthetic obturation is closure of the maxillectomy defect and separation of the oral cavity from the sinonasal cavities by use of different bulb designs. The aim of this study was to evaluate the articulation performance of obturator patients with three different buccal extension designs. METHODS Five patients with palatal defects of comparable sizes at ages r...

OBJECTIVES The aim of the study was to volumetrically assess alterations of the ridge contour after socket preservation and buccal overbuilding. MATERIAL AND METHODS In five beagle dogs, four extraction sites were subjected to one of the following treatments: Tx 1: The socket was filled with BioOss Collagen and covered with a free gingival autograft from the palate (SP). Tx 2: The buccal bone...

OBJECTIVE The aim of the present study was to compare dentoalveolar changes in mandibular arch, regarding transversal measures and buccal bone thickness, in patients undergoing the initial phase of orthodontic treatment with self-ligating or conventional bracket systems. METHODS A sample of 25 patients requiring orthodontic treatment was assessed based on the bracket type. Group 1 comprised 1...

Energetic analysis of ecologically relevant behaviors can be useful because animals are energetically limited by available muscle mass. In this study we hypothesized that two major determinants of suction feeding performance, the magnitudes of buccal volumetric expansion and subambient buccal pressure, would be correlated with, and limited by, available muscle mass. At least four individuals of...
