Immunoscoring of epidermal growth factor receptor expression in recurrent cases of oral squamous cell carcinoma.

Background: Oral squamous cell carcinoma (OSCC) is a genetic disease with high prevalence and poor survival. Evaluation of recurrent tumor for a valid biomarker may serve as a predictive system for analyzing prognostic course of this disease. This study was designed to evaluate and compare the immunoscoring of epidermal growth factor receptor (EGFR) expression in recurrent cases with their matched regional/locoregional recurrence and non-recurrent cases of OSCC.

Escalating role of piezosurgery in dental therapeutics.

Dentistry, an art in science and tranquilizer in medicine, has seen a lot of changing concepts over a decade and one such novel innovation is piezosurgery. Piezosurgery is a true revolution in bone surgery as it fulfils both biological and technical criteria. It has a variety of applications ranging from minor surgical procedures to complex implantology, plastic and reconstructive surgeries.

Periosteal fenestration vestibuloplasty procedure for sulcus deepening in a hemimandibulectomy patient following implant therapy.

Ablative surgery of the jaws may be necessary when malignant disease or destructive benign disease occurs. Surgical reconstruction needs to include the restoration of masticatory function so that the quality of life after the operation is optimal. When resection includes part of the upper or lower jaw, the aim of reconstruction should encompass not only the restoration of aesthetics, speech and swallowing, but also the recreation of an alveolar ridge suitable for prosthetic rehabilitation of the dental occlusion.

Impaction of primary anterior teeth is very rare. A tooth that fails to erupt into normal functional position by the time it normally should is considered impacted. A rare case of impacted dilacerated maxillary primary incisors in a 3-year-old child is presented.

Amelogenin: A novel protein with diverse applications in genetic and molecular profiling.

Tooth enamel is a unique entity among all mineralized tissues because of the presence of high mineral content. It is non collagenous and does not undergo resorption and remodelling. Its formation occurs through a transient collaborating network of enamel matrix proteins which controls hydroxyapatite crystal growth and orientation.

A solitary crateriform ulcer of the lower lip: a case report with review of literature.

Keratoacanthoma (KA) is a relatively common skin lesion. We report a case of KA-mimicking squamous cell carcinoma in a 40-year old smoker, who was also having speckeled leukoplakia on the buccal mucosa. The present case highlights the importance of histopathological diagnosis, as the treatment in latter case is aggressive, which is unnecessary if attempted with KA.

Prosthetic rehabilitation of ocular defect using digital photography: a case report.

The fundamental objective in restoring a congenital as well as acquired defect of eye with an ocular prosthesis is to enable the patient to cope better with the difficult process of rehabilitation after an enucleation or evisceration. A cosmetically acceptable prosthesis is that reproduces the color, form and orientation of iris and allows the patient to return to accustomed lifestyle. A sequence of steps for construction of custom-made ocular prostheses is outlined in this case report using the advantages of digital imaging technique.

Clinical efficacy of subgingivally delivered 0.5% controlled release azithromycin gel in the management of chronic periodontitis.

Background: Recent developments suggest that the local delivery of antimicrobials into periodontal pockets can improve periodontal health. Azithromycin (AZM) has a wide antimicrobial spectrum of action toward anaerobic bacteria as well as Gram-negative bacilli. It is effective against periodontal pathogens such as Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis.

Keratocystic odontogenic tumor: a review.

The odontogenic keratocyst is a very well known odontogenic cyst. There are many types of cysts of the jaws, but what makes the odontogenic keratocyst unusual are its characteristic histopathological and clinical features, including potentially aggressive behaviour, high recurrence rate, and an association with the nevoid basal cell carcinoma syndrome. The characteristic histologic feature i.
