Article: Solitary peripheral osteomas of the jaws.
[show abstract] [hide abstract]
ABSTRACT: Osteoma is a benign osteogenic tumor composed of cancellous or compact bone, classified as peripheral, central, or extraskeletal. Peripheral osteomas are uncommon. Excluding the maxillary sinuses, the maxilla is a rare site for osteomas. The purpose of this report was to describe clinicopathological and radiological features of two peripheral osteomas occurring in the jaws, one located in the mandible and another in the edentulous maxillary alveolar ridge. The tumors were asymptomatic and were fully excised without any complications or recurrence. The lesions were submitted to histopathological analysis and diagnosed as peripheral osteoma, compact type.Imaging science in dentistry. 06/2012; 42(2):99-103. -
Article: Effect of low-level laser therapy in the treatment of burning mouth syndrome: a case series.
[show abstract] [hide abstract]
ABSTRACT: The aim of this study was evaluate the effect of low-level laser therapy (LLLT) in the treatment of burning mouth syndrome (BMS) patients. BMS is a clinical condition characterized by a burning sensation in a morphologically normal oral mucosa, without association with systemic disorders. Ten patients with oral burning sensation were included in the study. After careful evaluation of medical history and oral examination, the diagnosis of BMS was established. All patients were submitted to one weekly session of LLLT for 10 weeks. A continuous wavelength of 660 nm, power 40 mW, 20 J/cm(2), 0.8 J/point, with each point irradiated for 10 sec. In all sessions the burning intensity was evaluated with a 10-cm visual analogue scale (VAS), with 0 indicating no symptoms and 10 indicating the worst burning possible. The burning intensity evaluation by VAS was performed immediately before (VAS baseline) and immediately after each LLLT session. The nonparametric Wilcoxon test was used for statistical analysis, considering significance of 5%. All patients reported improvement in all sessions, with reduction in VAS scores by up to 58% in the tenth session. When only the VAS baseline of the first session was compared with the other sessions, there was a statistically significant reduction in VAS scores in the fourth (p=0.03), fifth (p=0.03), sixth (p=0.009), seventh (p=0.003), eighth, ninth, and tenth (all p=0.002) sessions. LLLT may be an alternative treatment for the relief of oral burning in patients with BMS.Photomedicine and laser surgery 12/2011; 29(12):793-6. · 1.76 Impact Factor -
Article: [Low intensity laser therapy effects on cell proliferation and differentiation: review of the literature].
[show abstract] [hide abstract]
ABSTRACT: Low energy laser has been used as an adjuvant therapy or as a therapeutic tool in many different areas of Dentistry. It is recognized by its anti-inflammatory and analgesic properties, and also as a tissue repair inductor. Low intensity laser property in stimulate cell proliferation during wound healing and its biomodulation mechanisms are discussed in this paper. These properties have already been established for cultured benign cells, but there is a controversy when extended to the spectrum of the malignant neoplastic process, normally generating great discussions. The objective of this work was to perform a literature review about the low intensity laser capacity in induce cell proliferation. The discussion is specially concerned about its effects on malignant cells.Revista do Colégio Brasileiro de Cirurgiões 08/2010; 37(4):295-302. -
Article: Comparison of the effects of the CO2 laser and chlorohexidine on the decontamination of infected cutaneous wounds: a histologic study in rats.
[show abstract] [hide abstract]
ABSTRACT: The aim of this study was to compare histologically the effects of CO2 laser and chlorohexidine gluconate (4%) on Staphylococcus aureus-infected cutaneous wounds. Wound infection constitutes a big risk for patients, and it is usually associated with increased morbidity, mortality and hospital costs. It is accepted that local treatment of these infections is effective. Standardized wounds created on the dorsum of 36 rats were infected with Staphylococcus aureus and treated during 6 days as follows: group I, chlorohexidine gluconate (4%) applied to the wound surface during 1 min during 6 days; group II, single CO2 laser irradiation (8 W, CW, unfocused, 8-cm focal distance, 81,530 W/cm(2)), maintaining surface debris; group III, single CO2 laser irradiation (8 W, CW, unfocused, 8-cm focal distance, 81,530 W/cm(2)), removing the surface debris. Seven days after wounding, the animals were killed and specimens taken for light microscopy. On control wounds, epithelial ulceration and neutrophylic and lymphoplasmocitary inflammatory infiltrate was observed. On group II, there was epithelial hyperplasia, areas of ulceration and intense neutrophylic and lymphoplasmocitary inflammatory infiltrate. In group III, there was a neutrophylic inflammatory infiltrate underneath the surface debris and below that intense lymphoplasmocitary inflammatory infiltrate. When the surface debris was removed (group IV), there was epithelial ulceration and mild lymphoplasmocitary inflammatory infiltrate and fibroblasts and collagen fibers. The results of this study show that infected wounds treated with 4% chlorohexidine show a more pronounced inflammatory reaction when compared to that observed when the CO2 laser is used, especially when surface debris are removed; surface debris removal on laser-treated wounds results in better and more rapid healing; the surface debris may act as a culture medium for bacterial growth or, because of its characteristics, it may act as a local irritant and delay healing.Journal of Clinical Laser Medicine & Surgery 07/2002; 20(3):123-7.
