In oral cavity neurogenic tumors are rare, especially if they are malignant. Neurofibromas are the benign tumors of nerve sheath origin involving multiple nerve fascicles of the smaller branches of peripheral nerves. They may present as solitary lesions or as a part of generalized syndrome of neurofibromatosis also known as von Recklinghausen's disease (VRD) or very rarely as multiple neurofibromas without VRD. Oral solitary neurofibromas are not uncommon, but histologically plexiform variant is a rare form...

Incontinentia pigmenti is a rare genodermatosis in which the skin involvement occurs in all patients. Additionally, other ectodermal tissues may be affected such as the central nervous system, eyes, hair, nails and teeth. The disease has an X-linked dominant inheritance pattern. But in our case, there was a mutation in the body cells due to incontinentia pigmenti. The dermatological findings occur in four successive phases. We report the case of a 10-year-old female presented cutaneous, dental and ophthalmic characteristic with 3 years follow-up...

STATEMENT OF THE PROBLEM: The presence of bacterial biofilms is the major cause of gingivitis and periodontitis, their mechanical removal is not often enough. Therefore, laser therapy and photodynamic therapy can be effective as adjunctive treatment. PURPOSE: This study aimed to evaluate the impact of these treatments on the level of gingival crevicular fluid (GCF), inflammatory mediators, and periodontal clinical status. MATERIALS AND METHOD: In this clinical trial, three quadrants were studied in 12 patients with chronic periodontitis aged 30-60 years...

STATEMENT OF THE PROBLEM: Use of cyclooxygenase inhibitors as chemotherapy agents has attracted the attention of a large number of investigators in recent years. Given the importance of cancer therapy, only a limited number of studies have been carried out to investigate the effects of cyclooxygenase inhibitors on specific cell lines. PURPOSE: This research aimed to determine the in vitro cytotoxic effects of cyclooxygenase inhibitors (COX-1 and COX-2 inhibitors) on KB, Saos-2, 1321N, U-87MG, SFBF-PI 39 cell lines...

STATEMENT OF THE PROBLEM: Dental caries is one the most prevalent diseases that affects humans throughout their lives. Streptococcus mutans (S. mutans) is recognized as the most important microorganism during tooth cariogenicity. Reducing this germ in oral cavity can reduce the rate of tooth decays in humans. PURPOSE: The present study compared the antimicrobial activity of ethanolic extract of Peganum harmala L. seeds and 0.2% chlorhexidine on S. mutans. MATERIALS AND METHOD: Agar diffusion technique and micro broth dilution method were employed to test the antimicrobial effects of these two agents on S...
