Comparative evaluation of effect of preoperative alprazolam and diclofenac potassium on the success of inferior alveolar, Vazirani-Akinosi, and Gow-Gates techniques for teeth with irreversible pulpitis: Randomized controlled trial.

Introduction: In teeth with irreversible pulpitis, successful local anesthesia is hard to achieve irrespective of the amount of local anesthesia and technique used. Such cases can be managed by concoction of pre-medications like anxiolytics, analgesics and effective local anesthesia. This double-blind, placebo-controlled study was planned to evaluate the effect of oral administration of alprazolam and diclofenac potassium on the success rate of inferior alveolar nerve block (IANB), Gow-Gates (GG) and Vazirani-Akinosi (VA) techniques for the root canal treatment of mandibular molars with irreversible pulpitis.

A Rare Case of Tamarind Seed Induced Oral Submucous Fibrosis in a 12-Year-Old Indian Boy.

Oral Submucous Fibrosis (OSMF) is a chronic debilitating, potentially malignant disorder of the oral cavity. It is characterized by restricted mouth opening which results due to abnormal accumulation of collagen in the sub-epithelial layers leading to dense fibrous bands in the mouth. The pathogenesis of the disease is believed to be multifactorial.

Salivary alterations in type 1 diabetes mellitus patients: Salivary glucose could be noninvasive tool for monitoring diabetes mellitus.

Background: Diabetes mellitus (DM) is an endocrine disease characterized by hyperglycemia, the pathogenic mechanisms by which hyperglycemia arises differ widely. Monitoring people with diabetes involve repeated estimations of plasma glucose either by finger pricks or by intravenous blood sampling. Hence, a noninvasive procedure for glucose measurements would be most precious under the circumstances.

Anterior deep bite malocclusion treated with connecticut intrusion arch: biomechanical consideration.

Most Class II division 2 malocclusion manifest a severe deep bite, the orthodontic correction of deep overbite can be achieved with several mechanisms one such mechanics is true intrusion of anterior teeth. Deep overbite correction by intrusion of anterior teeth affords a number of advantages which includes simplifying control of the vertical dimension and allowing forward rotation of mandible to aid in Class II correction. It also aid in correction of a high gingival smile line.

Lip repositioning.

Excessive gingival display is a frequent finding that can occur because of various intraoral or extraoral etiologies. This report describes the use of surgical lip repositioning technique for the management of a gummy smile associated with vertical maxillary excess and hypermobility of the upper lip. The procedure restricts the muscle pull of the elevator lip muscles by shortening the vestibule, thus reducing the gingival display when smiling.

Comparative evaluation of pre-emptive analgesic efficacy of intramuscular ketorolac versus tramadol following third molar surgery.

Pre-emptive analgesia aims at preventing the central nervous system from reaching a hyper-excitable state known as central sensitization, in which it responds excessively to afferent inputs. The clinical implication would be more effective pain management, thereby reducing post-operative pain and analgesic requirements. This study aimed at investigating the existence of pre-emptive analgesia and to compare the pre-emptive analgesic efficacy of im ketorolac [NSAID] versus tramadol [SYNTHETIC OPIOD] for post-operative pain management following third molar surgery.

Transmigration of mandibular canines.

The purpose of this paper is to present the first case of unusual reverse oblique (110 degrees to midsagittal plane) migration of mandibular right canine crossing the jaw midline and piercing the lower border of the mandible at the level of the opposite canine and also to report two more cases of transmigrated mandibular canine and one case of transmigrating mandibular canine. Mandibular canines are "cornerstone" of dental arch; their importance is manifested by their efficiency in masticatory function, stability of dental arch, and aid in maintaining natural facial expression. Early detection of this anomaly can help preserving these canines by orthodontic intervention or by surgical transplantation.

Bifid mandibular condyle.

A 20-year-old young male patient presented with limited mouth opening and cosmetic disfigurement since childhood. On examination, marked mandibular hypoplasia resulting in a convex facial profile was noted. Further radiographic investigation using orthopantomograph and CT scan with three-dimensional reconstruction revealed bifid mandibular condyle of the right side.

Intraosseous schwannoma of the mandible.

Schwannomas (neurilemmomas) are slow-growing, benign neoplasms derived from schwann cells, the sheath cells that cover myelinated nerve fibers. These tumors most commonly arise in the soft tissues of the head and neck, as well as on the flexor surfaces of the upper and lower extremities. Intraoral lesions are uncommon, however, and intraosseous schwannomas are even rarer.
