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...

Telomere length has garnered interest due to the potential role it may play as a biomarker for the cellular aging process. Telomere measurements obtained from blood-derived DNA are often used in epidemiological studies. However, the invasive nature of blood draws severely limits sample collection, particularly with children. Buccal cells are commonly sampled for DNA isolation and thus may prese...

The buccal morphology was compared between the sexes of the cardinalfish Apogon doederleini, in which males provide mouthbrooding. The brood size increased proportionally with male buccal space, which increased with the fourth power of the standard length. In the breeding season, males had a larger buccal space than females, whereas there was no sexual difference in the non-breeding season, sug...

Extracts prepared from tissue specimens of normal, non-tumourous human buccal mucosa, and cultured buccal epithelial cells and fibroblasts, exhibited O6-methylguanine-DNA methyltransferase (MGMT) activity by catalysing the repair of the premutagenic O6-methylguanine lesion in isolated DNA with rates of 0.2 to 0.3 pmol/mg protein. An SV40 T antigen-immortalized buccal epithelial cell line termed...

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...

OBJECTIVES To compare the effectiveness, side effects, and patient satisfaction of buccal versus vaginal misoprostol administration in first and second trimester induced abortions. METHODS In first trimester, women received oral mifepristone followed by misoprostol either by buccal or vaginal route. In second trimester, women received oral mifepristone followed by repeated doses of misoprosto...

OBJECTIVE In this study, we measured the cortical bone thickness in the mandibular buccal and lingual areas using computed tomography in order to evaluate the suitability of these areas for application of temporary anchorage devices (TADs) and to suggest a clinical guide for TADs. METHODS The buccal and lingual cortical bone thickness was measured in 15 men and 15 women. Bone thickness was me...

A 16-years-old female patient with painless swelling of the right side of mandible is described. She noticed the swelling from two years ago, without painful symptoms. Axial CT imaging showed buccal expansion with intact buccal and lingual cortical bone. The report of incisional biopsy was central odontogenic fibroma. Under general anesthesia the lesion was removed after ostectomy of buccal cor...
