Aggressive osseous commitment result by keratocyst odontogenic tumour: case report, radiographic and clinical standpoints.

Keratocystic odontogenic tumour (KCOT) previously known as odontogenic keratocyst was recently classified as a benign lesion characterized by an infiltrating pattern, local aggressiveness with the propensity to recurrence. It is thought to arise from the dental lamina. Pain is usually not associated with KCOT until swelling occurs, and it commonly affects the posterior mandible.

CO(2) Laser Surgery and Prosthetic Management for the Treatment of Epulis Fissuratum.

The aim of this study was to present a case report of the surgical removal of hyperplasia in the oral cavity, using carbon dioxide (CO(2)) laser radiation and rehabilitation with a complete denture. Epulis fissuratum occurs in complete denture patients, because a constant irritative action induces the mucosa to grow under poorly fitting dentures. These lesions must be removed, and to avoid a relapse, new complete dentures should be made to maintain healthy surgical tissues.

Healing process after surgical treatment with scalpel, electrocautery and laser radiation: histomorphologic and histomorphometric analysis.

The aim of this study was to evaluate and compare the healing process after surgical treatment of chemically induced lesions in the lateral edge of tongue of hamsters performed with scalpel, electrocautery, carbon dioxide (CO(2)) laser radiation or neodymium:yttrium-aluminum-garnet (Nd:YAG) laser radiation. Eighty hamsters of both sexes were used and examined at postoperative days 7, 14, 21 and 28 by histological and histomorphometric analysis of the skeletal muscle fibers. In the histological analysis it was observed that the dynamics of the healing process was faster in the group treated by scalpel than in the other groups.

Surgical treatment of earlobe keloid with CO2 laser radiation: case report and clinical standpoints.

Keloids are considered to be benign hyperproliferative growths of dense fibrous tissue and overabundant deposition of disorganized, thick, hyalinized collagen that result from an abnormal tissue response to cutaneous injury. Keloids do not have a specific cause, although genetic predisposition is heavily implicated. We present a case report of a patient with an earlobe keloid that was treated with carbon dioxide laser radiation (CO(2)) with an 0.

Homogenous amniotic membrane as a biological dressing for oral mucositis in rats: histomorphometric analysis.

Objective: Oral mucositis is a frequent and significant side effect of chemotherapy and/or radiation therapy. The purpose of this study was to evaluate the effects of the homogenous amniotic membrane (HAM) as a biological dressing for oral mucositis induced by 5-fluorouracil (5-FU) in the labial fornix region of inferior incisors in rats.

Methods: Sixty rats were divided into three groups: control (50% acetic acid), 5-FU (50% acetic acid and 5-fluorouracil-induced oral mucositis) and 5-FU+HAM (50% acetic acid and 5-fluorouracil-induced oral mucositis, and treated with HAM).

A phase III randomized double-blind placebo-controlled clinical trial to determine the efficacy of low level laser therapy for the prevention of oral mucositis in patients undergoing hematopoietic cell transplantation.

Introduction: Oral mucositis (OM) is a significant early complication of hematopoietic cell transplantation (HCT). This phase III randomized double-blind placebo-controlled study was designed to compare the ability of 2 different low level GaAlAs diode lasers (650 nm and 780 nm) to prevent oral mucositis in HCT patients conditioned with chemotherapy or chemoradiotherapy.

Materials And Methods: Seventy patients were enrolled and randomized into 1 of 3 treatment groups: 650 nm laser, 780 nm laser or placebo.

Surgical treatment of erythroleukoplakia in lower lip with carbon dioxide laser radiation.

Erythroplakia is considered to represent a premalignant condition and is felt to be at high risk to progress to oral cancer development. When the lesion presents with red and white mucosal alterations concomitantly, the term erythroleukoplakia is used. However, in erythroleukoplakia lesions, the red or erythroplakia areas have been shown to be most likely to demonstrate dysplastic changes compared to the white hyperkeratotic areas.

Treatment of developmental defect of upper lip with carbon dioxide laser radiation (CO2): first surgical time.

With the exception of the cleft lip, developmental defects (DD) of the lip are rare. The upper lip originates from the ectomesenchyme and is formed by the merging of the nasal medial and lateral processes with the maxillary process. Disturbances during this formation period can cause DD with functional and/or esthetic repercussions.

Effects of copper vapor laser radiation on the root canal wall of human teeth: a scanning electron microscope study.

Objective: The aim of this study is to analyze the effects of copper vapor laser radiation on the radicular wall of human teeth.

Materials And Methods: Immediately after the crowns of 10 human uniradicular teeth were cut along the cement-enamel junction, a chemical-surgical preparation of the radicular canals was completed. Then the roots were longitudinally sectioned to allow for irradiation of the surfaces of the dentin walls of the root canals.

Effects of copper vapor laser irradiation (lambda = 510.6 nm) on the enamel and dentine of human teeth: an ultra-structural morphologic study.

Objective: A morphological and ultra-structural study of copper vapor laser (lambda = 510.6 nm) effects on enamel and dentine was performed to show the effects of this radiation.

Methods: A total of 15 human molars were cut in half; 15 pieces were separated for irradiation on enamel and 15 for dentine.
