BACKGROUND Ectopic thyroid tissue very rarely occurs in the buccal region. Even more rarely encountered is the papillary carcinoma arising in the ectopic tissue. METHODS AND RESULTS We herein present a 78-year-old female patient admitted with a giant, buccal mass that developed within the previous 2 years. Physical examination revealed a vegetative mass on the left buccal region without any c...

BACKGROUND The need for and consequence of sacrificing the buccal branch of the facial nerve during parotidectomy is unknown. We sought to determine the indication, frequency, and functional outcome of buccal branch sacrifice. METHODS We conducted a prospective study of all cases of parotidectomy at a tertiary referral center. RESULTS Of 100 consecutive cases of parotidectomy, the buccal br...

Cerebral peptide 2 (CP2), a 41 amino acid neuropeptide, was identified because it was transported from the cerebral ganglia of Aplysia to other central ganglia. Immunocytology indicates that CP2 is distributed widely in the CNS and peripheral tissues of Aplysia. Most CP2-immunoreactive neurons were found in the cerebral ganglia and extensively overlap with the distribution of cerebral peptide 1...

AIM To identify factors that may influence ridge alterations occurring at the buccal aspect of the extraction site following immediate implant placement. MATERIAL AND METHODS In 93 subjects, single-tooth implants were placed immediately into extraction sockets in the maxilla (tooth locations 15-25). A series of measurements describing the extraction site were made immediately after implant in...

The purpose of this work was to study the effect of various permeation enhancers on the permeation of salbutamol sulphate (SS) buccal patches through buccal mucosa in order to improve the bioavailability by avoiding the first pass metabolism in the liver and possibly in the gut wall and also achieve a better therapeutic effect. The influence of various permeation enhancers, such as dimethyl sul...

OBJECTIVE Evaluate the esthetic perception and attractiveness of the smile with regard to the buccal corridor in different facial types by brachyfacial, mesofacial and dolichofacial individuals. MATERIAL AND METHODS The image of a smiling individual with a mesofacial type of face was changed to create three different facial types with five different buccal corridors (2%, 10%, 15%, 22% and 28%...

BACKGROUND New indications for misoprostol include medical abortion, cervical softening, induction of labor and treatment of postpartum hemorrhage. Various routes of misoprostol administration under study include oral, vaginal, buccal, sublingual and rectal. MATERIALS AND METHODS This was an open-label, randomized, cross-over study of the pharmacokinetic differences of buccal vs. sublingual m...

Aquatic pipid frogs, unlike other anurans, never show sole buccal ventilation cycle, and exhale air from the lung before aspirating air into the buccal cavity. To study the mechanism that pipid frogs lack the buccal cycle, respiratory motor activities were recorded from the isolated brainstem-spinal cord preparation of Xenopus laevis. Brainstem preparations of Xenopus exhibited the intermittent...

Objective(s): Salvia miltiorrhiza (SM) is a popular and classic herb in traditional Chineses medicines. The objective is to confirm the effects of aqueous extract of S. miltiorrhiza (ESM) and its main ingredient on the promotion of orthodontic tooth movement and healing of periodontal ligament in rat. Materials and Methods: Male Sprague-Dawley rats (n= 150) were divided into five groups: model ...
