The collection of buccal cells provides a noninvasive method for obtaining DNA for genetic studies. Here we report the results on buccal cell genotyping from our ongoing study of childhood leukemia in Northern California. We have collected buccal samples from children ranging in age from 4 months to 15 years using an interviewer- or nurse-administered protocol using a cytology brush. Initial re...

OBJECTIVE To study the efficacy, safety, and acceptability of oral immediately swallowed and buccal misoprostol 800 mcg after mifepristone 200 mg for terminating pregnancy through 63 days since the last menstrual period (LMP). METHODS This seven-site study randomly assigned 966 women seeking abortions to oral or buccal misoprostol 800 mcg 24-36 hours after mifepristone 200 mg with 7-14-day fo...

The buccal mucosa is the site with the highest risk of contracting a malignancy in habitual betel quid chewers who expose the buccal mucosa to high doses of carcinogens. Of all oral cancers, those of the buccal mucosa are associated with the poorest prognoses. Therefore, it would be helpful to have an animal model to evaluate new treatment modalities for buccal mucosa cancer. In the present stu...

We evaluated the feasibility and efficiency of using swabs to collect buccal epithelial cells from small (2to 13-g) birds as a source of DNA for genetic studies. We used commercially available buccal swab kits to collect samples from 42 adult and 39 nestling (4to 8-day-old) black-capped chickadees (Poecile atricapillus) and from 6 4-day-old nestling boreal chickadees (P. hudsonica). We compared...

The mandibular infected buccal cyst or mandibular bifurcation cyst is a cystic lesion that occurs on the buccal surface of the permanent mandibular first or second molar in children aged around 6-8 years. We report the clinical, radiographic, and histological features and the treatment of a mandibular infected buccal cyst of the first molar in a 7-year old child. 1 year follow up after the enuc...

We report the first 3 cases in which CT disclosed herniation of the body of the buccal fat pad into the maxillary antrum. Only 20 cases of traumatic herniation of the buccal fat pad have been described in the literature. In all except one instance, the buccal fat pad herniated into the oral cavity. The only previous report of herniation of the buccal fat pad into the maxillary antrum is in an a...

PURPOSE The aim of this study was to analyze the anatomical dimensions of the buccal bone walls of the aesthetic maxillary region for immediate implant placement, based upon cone-beam computed tomography (CBCT) scans in a sample of adult patients. METHODS Two calibrated examiners analyzed a sample of 50 CBCT scans, performing morphometric analyses of both incisors and canines on the left and ...

The Japanese Orthopaedic Association hip disease evaluation questionnaire (JHEQ) was established as a new patient-reported outcome for patients with hip disease. We developed a JHEQ application beta version for tablet computers. The application has a slider system to input visual analogue scale (VAS) measurements. The purposes of this study were 1) to test whether the VAS that was acquired from...
