Kuding tea (Ilex kudingcha C.J. Tseng) is drunk widely in China. The in vitro anticancer effects of Kuding tea were evaluated in TCA8113 human tongue carcinoma cells using a 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyltetrazolium bromide (MTT) assay. At a concentration of 200 μg/ml, Kuding tea exhibited an inhibitory effect of 75% in TCA8113 cells, which was higher than that observed at concentrat...

OBJECTIVE The objective of the present study was to investigate the pain on injection of articaine with adrenaline, prilocaine with phenylpressin , and lidocaine with adrenaline. STUDY DESIGN The study sample was comprised of 497 consecutively seen patients received 497 maxillary buccal infiltration injections or inferior alveolar block injections of 4% articaine with 1:200.000 adrenaline, 3%...

The buccal ganglion of Aplysia contains a central pattern generator (CPG) that organizes sequences of radula protraction and retraction during food ingestion and egestion. Neurons B63 and B34 have access to, or are elements of, the CPG. Both neurons are depolarized along with B31/B32 during the protraction phase of buccal motor programs. Both cells excite the contralateral B31/B32 neurons and i...

OBJECTIVE To compare the injection pain and speed of local anesthetic effect induced by tissue infiltration of mepivacaine 2% with epinephrine 1:100,000 versus articaine 4% with epinephrine 1:100,000 in securing mandibular first molar pulp anesthesia. MATERIALS AND METHODS Totally, 25 patients were recruited in a crossover, randomized, double-blind study. Each subject received injections of m...

Objective: Pax-7 and Myo-D regulate satellite cells’ activation differentiation, thus muscle regeneration following damage. This research aimed to investigate the effect of Thymoquinone (TQ) on skeletal 7,12-dimethylbenz-(a)-anthracene (DMBA)-induced injury in hamster buccal pouch via immunohistochemical assessment expression. Material Methods: 65 male golden Syrian hamsters were divided into 3...

Objective: To evaluate the efficacy of pre-cooling and use higher gauged needles in reducing pain during local anesthetic infiltration. Material Methods: We conducted a split-mouth randomized controlled trial among 70 patients who require bilateral maxillary (LA) injections for dental treatment. After applying topical anesthetic, each participant received four injections, two on buccal palatal ...

In the land snail Achatinafulica, it has been suggested that two pairs of cerebral neurones, ventral cerebral distinct neurones (v-CDNs) and Cl neurones, and a pair of buccal motoneurones (BLs) are involved in the control of rhythmic motor activity (RMA) in the buccal ganglia. These neurones, when tonically fired by depolarizing current injection, could individually initiate and maintain RMA in...

i ntroduction: our study was designed to assess the effect of the submucosal injection of dexamethasone on postoperative discomfort after surgical removal of impacted mandibular third molars. m at erials and methods : twenty six patients with bilaterally bony impacted mandibular third molars were recruited to this split mouth study. on the study side, prior to surgery, 8 mg of dexamethasone was...

background there is a potential risk for malignancy in patients with diabetes mellitus. theoretically, a noninvasive method for detection of precancerous changes can be conducted on oral exfoliated cell smears. objectives in this study, the immunocytochemistry of p53 in exfoliated oral mucosal cells in patients with type 2 diabetes was investigated. patients and methods oral mucosal smears were...
