The effect of different parameters of low-level laser used in the treatment of oral mucositis, on the viability and apoptosis of oral squamous cell carcinoma cells: In vitro study.

Oral mucositis is a complication of chemo/radiotherapy. To assess the impact of various power levels of diode-laser on the survival and expression of apoptosis-related genes in oral cancer cells, it is crucial to consider the potential existence of malignant cells within the treatment region and the reliance of laser effectiveness on its specific characteristics. Cal-27 cells were cultivated and exposed to a 660 nm-diode-laser at power levels of 20, 40, and 80 mW, alongside non-irradiated control cells.

Treating Parafunctional Habits for Alleviating Temporomandibular Disorder and Lower Back Pain: A Phase II Clinical Trial.

Temporomandibular disorders (TMDs) include a series of signs and symptoms in the temporomandibular joints (TMJ) and muscles of mastication, which are associated with or caused by parafunctional habits. Many of these patients also suffer from lumbar pains. This study aimed to evaluate the effectiveness of treating parafunctional habits in alleviating symptoms of TMD and lower back pain.

Oropharyngeal Candida Colonization in Patients with Acute Myeloid Leukemia.

Objectives: Oral candidiasis has increased in recent years because of the increasing number of high-risk populations. The prevalence of Candida species is different worldwide because of the difference between population characteristics, sampling protocols, and geographic regions. Therefore, determining the more prevalent Candida species in different geographic regions seems essential.

The Effect of Laser Bio-modulation on Dysplastic Lesions, an Animal Study.

Potentially malignant disorders are one of the clinical challenges. Dysplasia in these lesions can be a predictor of more potential for malignant changes. Photo-bio-modulation in benign lesions has advantages, but there is doubt on its safety in potentially malignant lesions.

Effects of 660 nm and 810 nm Low-Power Diode Laser on Proliferation and Invasion of Oral Cancer Cells in Cell Culture Media.

In the present study, the effects of 660 and 810 nm diode laser on the proliferation and invasion of cancer cells were investigated. Sixteen plates of oral cancer cells originated from tongue SCC were irradiated with diode laser at 660 nm (40 and 80 mW) and 810 nm (100 and 200 mW) with the energy density of 4 J cm . One plate received no irradiation (the control).

Comparative Efficacy of Topical Curcumin and Triamcinolone for Oral Lichen Planus: A Randomized, Controlled Clinical Trial.

Objectives: Lichen planus (LP) is a chronic inflammatory mucocutaneous disease. Its treatment is often symptomatic and includes topical and systemic corticosteroids. Although corticosteroid therapy is usually successful, it has side effects and thus, an alternative treatment is favorable.

Serum and Saliva MMP-3 in Patients with OLP and Oral SCC.

Background: Matrix metalloproteinase-3 (MMP-3) plays a key role in development of cancer. The purpose of this study was to assess MMP-3 in the serum and saliva of patients with oral lichen planus (OLP) and oral squamous cell carcinoma (OSCC).

Materials And Methods: Thirty patients with OLP (8 reticular and 22 erosive forms), and 20 patients with OSCC (6 in low stage and 14 in advanced stage), were enrolled in this study, conducted at the Cancer Department, Clinic of Oral Medicine, Tehran University of Medical Sciences.

Comparison of oral lesion prevalence between renal transplant patients and dialysis patients.

Objective: Renal transplantation is performed in patients with end stage renal disease as the best treatment plan. However, different complications may occur in these patients due to the direct consequences of the renal disease or drug-induced suppression of the body immune system. The main objective of the present study was to compare different oral lesions in patients receiving renal transplantation with the patients undergoing dialysis referred to two hospitals in Tehran, Iran.

Oral osteosarcoma: a case report and analysis of previously reported cases.

Osteosarcoma is the most common malignancy of mesenchymal cells after hematopoietic neoplasms. Most originate within bones, but the occurrence of this malignancy in the jaw bones is rare. There is controversy about the characteristics of this tumor in the literature.

Non-syndromic bilateral dentigerous cysts associated with permanent second premolars.

The dentigerous cyst is one of the most common developmental odontogenic cysts in the jaw. Occurrence of the bilateral dentigerous cyst is uncommon, and frequently associated with syndromes like basal cell nevus syndrome or cleidocranial dysplasia. There are few reports on the presence of bilateral dentigerous cyst in nonsyndromic patients, and most of these are associated with first and third molars.

Oral Squamous cell carcinoma with an unusual clinical manifestation: a case report.

Introduction: Squamous cell carcinoma is the most common malignant tumor of the oral cavity and one of the 10th most common causes of death. It arises from dysplastic oral squamous epithelium. By considering the pathogenesis of squamous cell carcinoma, the smooth and intact surface for this lesion is not usual.

A new approach to root formation.

In endodontics, treatment of an open apex tooth with necrotic pulp is a problem. It seems that with promotion of remnants of Hertwig's epithelial sheath or rest of malassez accompany with a good irrigation of root canal we can expect root formation. (Iranian Endodontic Journal 2008;3:42-43).

Agreement between Clinicians in Determining the Root Canal System in Radiographic Images.

Introduction: The aim of this study was to compare a clearing technique with conventional radiography in studying certain features of the root canal system in single root premolars. A secondary aim was to assess inter examiner agreement for these features using radiographs.

Materials And Methods: Fifty-eight recently extracted single rooted premolars were included in this study.
