the desire to achieve cosmetic rejuvenation and reduce effects of aging and photodamage urged scientists to develop effectual techniques which have minimal side effects and impressive long-term efficacy. traditional ablative resurfacing laser therapy has been used for several years;however, it has harmful side effects on the patient’s skin such as dyspigmentation, persistent erythema, infection...

introduction: epulis fissuratum is often formed as a result of a poor fitting denture. the conventional treatment for this fibrous hyperplastic tissue is to excise it using a scalpel and to close the wound by a continuous or an interrupted suture. the increased utilization of lasers in dentistry also includes the utilization of carbon dioxide (co2) lasers in place of surgical scalpels in soft t...

BACKGROUND Fractional CO2 -laser resurfacing is increasingly used for treating rhytides and photoaged skin because of its favorable benefit-risk ratio. A key outcome measure and treatment goal in aesthetic laser therapy is patient satisfaction. However, few data are available on patient-reported outcomes after fractional ablative skin-resurfacing. OBJECTIVES To compare patient expectations be...

The formation of linear hypertrophic scars along suture lines is a frequent and undesired event after the conventional thy-roidectomy. 1 Previous reports have described good therapeutic results in minimizing the scars with fractional lasers and intralesional steroid injections. 1-4 However, in the cases of narrow linear scars, the fractional laser can damage the surrounding tissue despite using...

introduction: the purpose of this study was to investigate the effect of 6w power carbon dioxide laser (co2) on the biologic compatibility of the sandblasting with large grit and acid etching (sla) titanium discs through studying of the sarcoma osteogenic (saos-2) human osteoblast-like cells viability. methods: sterilized titanium discs were used together with saos-2 human osteoblast-like cells...

Background. Cutaneous leishmaniasis is an endemic disease in Iran. Pentavalent antimonial drugs have been the first line of therapy in cutaneous leishmaniasis for many years. However, the cure rate of these agents is still not favorable. This study was carried out to compare the efficacies of intralesional glucantime with topical trichloroacetic acid 50% (TCA 50%) + glucantime and fractional ca...

Two postmenopausal LS patients, resistant to conventional therapies, were treated with fractional CO2 laser. The patients became asymptomatic shortly after the third treatment, and the vulva, introitus and clitoral areas looked healthy throughout the 6-month post-treatment follow-up period. Histological assessments showed a trophic epithelium with acantotic areas, without superficial hyperkerat...

Rhinophyma is a severe late complication of rosacea, which is characterized by progressive hyperplasia of sebaceous glands and connective tissue involving the lower two-thirds of the nose. It can be an emotionally devastating disorder, and serve as a medium for occult cancers and other health problems. Many surgical treatments have been advocated, as well as dermabrasion and laser therapy. In l...

Ablative fractional skin resurfacing represents a new possibility that allows for shorter downtime and minimizes the risk of possible side effects compared to classical full ablative Er:YAG and CO2 treatment. To evaluate the potential benefits of fractional treatment with Er:YAG for skin resurfacing, we performed a clinical and histological comparison of the healing process after fractional and...

BACKGROUND The use of CO2 or conventional erbium laser ablation or more recent nonablative laser photothermolysis for skin rejuvenation is associated with significant disadvantages. OBJECTIVE The objective was to assess the efficacy of the erbium:YAG laser (2,940 nm) using the "ablative" fractional resurfacing mode to improve photodamaged skin. METHODS A total of 28 patients, 27 women and 1...
