BACKGROUND This study investigated the impact of different surface treatments, including fractional carbon dioxide (CO2) laser on shear bond strength (SBS) of resin cement to lithium disilicate ceramic. MATERIALS AND METHODS In this in vitro study, 72 blocks of IPS e.max CAD ceramic were randomly divided into six groups in terms of treatment (n = 12). Group 1 underwent etching with 9.6% hydro...

Ultra-pulsed fractional CO2 laser is an efficient, precise, and safe therapeutic intervention for skin refreshing, although accompanied with prolonged edema and erythema. In recent years, autologous platelet-rich plasma (PRP) has been proven to promote wound and soft tissue healing and collagen regeneration. To investigate whether the combination of PRP and ultra-pulsed fractional CO2 laser had...

Fractional continuous wave CO2 laser resurfacing is used to improve photodamage, wrinkles, and acne scarring by surface ablation and by using heat to activate natural collagen production and dermal remodeling. In this study, the author examined the efficacy and safety of nonincisional continuous wave fractional CO2 laser blepharoplasty in the upper lid. Standard lid measurements including margi...

Syringoma is a benign tumor of eccrine origin which arises from eccrine ducts. Syringomas are most commonly found on the eyelids in middle-aged women. Traditional treatments include surgical excision, curettage, peelings, dermabrasion and laser. We report on the successful use of fractional laser on periocular syringomas. A 53-year-old female patient with multiple periorbital syringomas underwe...

a 47 year-old woman presented with eight-month history of tattoo allergic reaction of eyebrows after botulinum toxin a injection that was resistant to oral, topical and intralesional injection of corticosteroids. multiple sessions of treatment with co2 fractional laser resulted in significant flattening of allergic papules and plaques as well as reduction of tattoo pigmentation

A recent advancement in the treatment of burn scars has been the use of the carbon dioxide (CO2) laser to perform fractional photothermolysis. In this analysis, we describe our results and patient-reported outcomes with the use of fractional CO2 laser for the treatment of burn-related scarring. We performed a retrospective study of all patients who underwent CO2 laser procedures for treatment o...

Ablative laser resurfacing is an effective treatment for atrophic acne scars. However, it often induces complications such as edema, prolonged erythema, scarring and hyperpigmentation. Therefore, a new concept of laser treatment called fractional photothermolysis has been designed to create microscopic thermal wounds to achieve skin rejuvenation treatment of atrophic acne scars. This study was ...

BACKGROUND/OBJECTIVE Hyperpigmentation occurs in more than 37% of dark-skinned subjects treated with a fully ablative CO2 laser device. This study assessed the risk of postinflammatory hyperpigmentation (PIH) in subjects with skin types 4 and 5 treated once with a specific protocol of treatment using a fractional CO2 laser. METHODS Seven subjects with photodamaged skin received a single facia...

Medical therapy for Hailey-Hailey disease (HHD) generally only provides temporary suppression. Surgical intervention has been shown to prolong remission, but may lead to significant morbidity. Laser therapy is becoming the preferred method of treatment because of its successful results and lower risk of complications compared to surgical modalities. We report a case of fractional ablative carbo...
