Aims: The appropriate management of Medication-Related OsteoNecrosis of the Jaw (MRONJ) is still a challenge for dentists and oral surgeons and in these last years high-technology instruments have been proposed at the different steps of interventions, also combined with promoters of tissue repair.The aim of this report is to show the advantages of a combined approach (laser and PRP) for the treatment of MRONJ. Methods: It is described the case of a patient positive for MRONJ observed at the Odontostomatology and Maxillo-Facial Surgery Unit of the Hospital of Piacenza where surgical approach was performed by using different devices: Er:YAG laser (2940 nm) to remove and vaporize necrotic hard tissue until bleeding bone; Platelet-Rich Plasma (PRP) to stimulate hard and soft tissue healing; diode laser (808 nm) to biostimulate the surgical site...

Chronic lower extremity ulcers (CLEUs) have a high prevalence and are difficult to treat due to their various aetiologies. The aim of this study is to evaluate the results achieved in treating CLEUs using an Erbium: YAG (Er:YAG) laser with RecoSMA technology. This laser emits thousands of microbeams of energy causing superficial epidermal ablation and a separation of dermal fibres due to a mechanical-acoustic and resonance effect. The evaluation of the results achieved was carried out by questionnaires completed by 18 patients enrolled in the study...

Background and Objectives: From year 2003 we treated positively 251 patients with Traumatic Spinal Cord Injuries (TSCI), using Non-Surgical Laser Therapy (NSLT). In order to increase muscle strength, we have also started using a physical therapy practice called Grimaldi's Muscle Shortening Manoeuvre (GMSM)The goal of our study is to obtain objective data suggesting the real effectiveness of the association of these two treatments. Study Design and Methods: In 2015, 10 patients with incomplete TSCI were enrolled...

Background and aims: The purpose of this study was to investigate the effect of low-level laser therapy (LLLT) on radial bone fracture gap healing in a rabbit model. Materials Subjects and Methods: Thirty male white New Zealand rabbits under general anesthesia had a 3mm slice of radial bone surgically removed. Fifteen rabbits were treated by 830 nm laser at 4 J/cm(2) and 15 were used as non-treated controls. Callus development was assessed by X-ray and radiographs every 7 days for 3 weeks...

Background and Aim: Wisdom teeth remains impacted in the jaw due to several reasons and surgery of impacted wisdom teeth is one of the most common surgeries in dental clinics. Pain, swelling and trismus are the common complications after this surgery which affect quality of life. In articles, various methods are introduced to control immediate inflammatory-response associated with third-molar surgery. The aim of this study is to evaluate the adjunctive effect of low-level laser Therapy on pain, swelling and trismus after surgical removal of impacted lower third molar...

Objectives: This study aimed to assess the effect of surface treatment by bur and laser and application of universal adhesive on repair bond strength of composite resin. Materials and Methods: A total of 120 composite blocks measuring 6×4×4 mm were fabricated of Filtek Z250 composite. All samples were subjected to 5,000 thermal cycles and divided into two groups for surface preparation by bur and by Er,Cr:YSGG laser (n = 60). The surfaces were then etched with orthophosphoric acid, rinsed with water and divided into three groups (silane, silane plus Single Bond and silane plus Single Bond Universal)...

BACKGROUND AND AIM: Minocycline therapy for acne vulgaris is associated with the occasional induction of various types of unsightly and often persistent hyperpigmentation, which is frequently resistant to hydroquinone treatment. Pigment-specific lasers have achieved some success with multiple treatment sessions. Recently, the picosecond domain 755 nm alexandrite laser (ps-Alex) has attracted attention in tattoo removal. The present study reports on the successful treatment, in a single ps-Alex session, of minocycline-associated pigmentation...

BACKGROUND AND AIMS: A paradigm shift towards noninvasive body contouring has occurred over the past few years. Radiofrequency (RF) is one popular treatment method. Noncontact-type RF systems with frequencies in the tens of megahertz represent a novel approach. The current pilot study investigated the efficacy of an interesting combination of extracorporeal shock wave therapy (ESWT) and an apoptosis-inducing RF (AiRF) system for circumferential reduction. SUBJECTS AND METHODS: Twenty-seven females, ages ranging from 13-69 years, (mean age 37...

BACKGROUND AND OBJECTIVES: Autogenous gingival grafts are considered the "gold standard" for gingival augmentation, however they require a second surgical site for graft harvesting. Apically positioned flaps (APFs) represent an alternative method in soft tissue augmentation procedures. Limited information is available relative to the effectiveness of laser-mediated APF in augmenting keratinized gingiva (KG). The aim of this paper is to evaluate soft tissues changes following APF using CO2 laser in mandibular incisors with minimal KG and high labial frenum attachment...

BACKGROUND AND AIMS: The aim was comparison of enamel remineralization after application of APF, TiF4 and CO2 laser alone or in combination. MATERIALS AND METHODS: Enamel blocks were prepared from human third molars. The initial surface hardness was determined by Vicker's hardness tester. The samples underwent a demineralization regimen for 7 days to produce artificial initial caries. The hardness of enamel blocks with white spot lesions was measured, and the samples which had the mean hardness change of 65-90%, were selected, and randomly divided into 5 groups (N=15): G1: control; G2: APF 1...

BACK GROUND AND AIM: production of collagen by fibroblast cells is a key component in wound healing. Several studies have shown that low level laser therapy (LLLT) and propolis extract stimulate collagen Type I production. The aim of this study is to evaluation the combined effect of LLL helium neon (632.8 nm) and Iranian propolis extract on collagen Type I gene expression by human gingival fibroblasts (HGF3-PI 53). METHODS AND MATERIALS: Human gingival fibroblasts after culturing divided into six experimental groups: G1-control group, which received no irradiation and propolis extract, G2-irradiated at1...

BACKGROUND AND AIMS: Bleaching might affect structural properties of composite materials, and lead to monomer release. This study aimed to evaluate the effect of Laser-assisted and conventional in-office bleaching on the release of BIS-GMA, TEGDMA, and UDMA monomers from a nanohybrid and a microhybrid BIS-GMA based composite. MATERIALS AND METHODS: 32 samples of each composite, were divided into 4 subgroups; subgroup 1: Conventional in-office bleaching (CIB) with the Opalescence Boost PF 38% gel, subgroup 2: Laser-assisted bleaching (LBO) with the Opalescence Boost PF 38% gel, subgroup 3: Laser-assisted bleaching (LBH) with the JW Power bleaching gel, subgroup 4: (CO) control without bleaching...

BACKGROUND: Although surgical treatment protocols for cleft lip and palate patients have been established, many patients still have some soft tissue defects after complete healing from surgical interventions. These are excess soft tissue, high attached fraena and firmed tethering scares. These soft tissue defects resulted shallowing of vestibule, restricted tooth movement, compromised periodontal health and trended to limit the maxillary growth. The aim of this case report was to present a method of correcting soft tissue defects after conventional surgery in cleft lip and palate patient by using combined laser surgery and orthodontic appliance...

BACKGROUND: Peripheral ossifying fibroma associated with neonatal tooth extraction is a rare, benign reactive lesion, but its nature and location often scares the patient & parents for possibility of neoplasm. A high recurrence rate makes its histopathological examination and long term follow up important. CASE REPORT: A 2 months old boy presented with enlarging soft tissue growth on the anterior mandibular ridge. The history revealed extraction of two neonatal teeth at 2 weeks of age...
