Currently a wide range of instruments for surgical procedures on the bony structures of the orbits is offered. Each of them has its advantages and disadvantages. Cutter causes less injury, in comparison with a chisel or an ultrasonic saw [15]. In using a drill during surgery there was an increase in temperature of bone edge of the opening above acceptable values [17]. The use of low frequency ultrasonic tools allows you to create holes in the bones of any desired size and shape with smooth edges [5, 11, 16, 20]. The disadvantages of this method include the heating of tool’s tip up to 140° during prolonged continuous action [6]. Thus, techniques using tools for formation of the bone window require further study and improvement. Aim: to compare surgical equipment for bone window formation in modeling an orbital decompression. Materials and methods. In an experimental study in vivo, 12 surgical interventions on the scapula on both sides were performed in 6 Chinchilla breed rabbits. On the right side, the formation of a bone window was carried out by the ultrasonic bone scalpel MISONIX, on the left side - by a drill. Results. It was found that during first 7-21 days there was more pronounced inflammation of soft tissues on the left side. At the same time, delayed proliferation and maturation of fibrous connective tissue was observed in comparison to the opposite side. Bone tissue inflammation and subsequent regeneration took place without significant differences on both sides. The experiment showed that the use of ultrasonic scalpel in flat bones creates less inflammation of surrounding tissues and the bone itself as compared to a diode laser. A.V. Kravchenko (2006) reports that, after exposure to a diode laser in an acute experiment there was a scalloped edge with an area of photocarbonization (charring) on the 7th and the 21st day; while the use of an ultrasonic scalpel did not create any signs of infiltrative inflammation, later on a nonspecific inflammation developed. Conclusion. Ultrasonic scalpel has a number of advantages when performing osteoperforation, such as time-saving during surgical procedure, control of the osteotomy process, less trauma to surrounding tissues during action and less pronounced inflammatory response of the wound during early postoperative period.

Continuously evolving laser devices can be used in various fields; they are an alternative to the traditional cold blade surgery to perform biopsies of oral soft tissues. The aspect focused on in this paper is the possibility to use the 445 nm diode laser (Eltech K-Laser srl, Treviso, Italy) in complete safety, by evaluating its thermal effects during microscopy. A histological evaluation of the alteration of the peri-incisional edges on 10 samples was realized. All excisional biopsies were related to clinically unsuspected lesions and performed by the same expert operator. The surgical procedure was performed with the same laser parameters and the same pathologist evaluated the thermal effect on the samples. An average value of the detected tissue alteration was calculated; the average damage of the epithelium was 650.93 μm, while in the connective tissue it was 468.07 μm. In all the cases a clear diagnosis was possible, and no clinical complications were observed; so, the 445 nm diode laser proved to be a device that can be safely used for biopsies of clinically unsuspicious lesions. Due to the small number of cases, this in vivo preliminary experience needs to be extended.

Improving the quality of restoration of the destroyed coronal part of the teeth by orthopaedic methods has led to significant scientific and clinical interest and has been discussed in numerous reports, but the issues on reparative regeneration and restoration of the gingival margin relief in the area of ​​the anterior group of teeth after reconstructive orthodontic measures in the case of restoration of destroyed tooth crowns and deep subgingival carious destruction have not been sufficiently studied yet. The purpose of this study was to investigate the microbiological peculiarities of applying a clinical diagnostic complex of manipulations designed to restore anterior teeth with cast posts to provide the grounds for long-term favourable outcomes of further orthopaedic treatment in order to obtain aesthetic appearance, taking into account the state of the surrounding soft tissues. To carry out high-quality preparation of periodontal tissues around the abutment tooth, patients underwent gingivectomy using a scalpel with a disposable blade, diode laser electrocoagulation and coagulation. The effectiveness of each method of the preparation of the marginal gingiva was evaluated by the findings of clinical and microbiological studies. We have found out all three tested methods of forming a new gum relief in the root area of ​​a preserved tooth can significantly improve the qualitative and quantitative composition of the microflora in the stump area. A significant decrease in the frequency of biotope colonization by pathogenic and transient microorganisms and the improvement of the species composition in the local oral microbiocenosis can be achieved by cutting the hypertrophied epithelial edge of the cervical area with a microsurgical scalpel and using laser coagulation. Clinical and microbiological studies have confirmed the effectiveness of the clinical diagnostic complex of techniques for preparing the marginal gum around the root of the tooth, which is planned for orthodontic treatment with a post and an inlay. The use of a diode laser has been found to show the highest efficiency compared to other presented methods. All of the above techniques can be used in dental practice as methods of choice.

Gingival Depigmentation

INTRODUCTION An esthetic smile is a perfect balance between hard and soft tissues of the mouth. Gingiva plays an important role in the esthetic appearance of an individual. Gingival pigmentation is considered to be unaesthetic by patients, and it may have a psychological impact on them. Gingival depigmentation is a periodontal plastic surgery procedure, and variety of depigmentation techniques have been described in the literature. The aim of this study was to compare the efficacy of diode laser and scalpel in gingival depigmentation procedure. MATERIAL AND METHOD A total of 12 patients with age range between 20 -40 years were selected in the randamized, split mouth study. The maxillary arch was divided into two segments: 1.Segment I- right first premolar to right central incisors. 2.Segment II- left first premolar to left central incisors. These two segments were randomly assigned to surgical scalpel and diode laser techniques modalities. The research included the following clinical evaluation parameters at baseline and 3 months: Dummet Oral Pigmentation Index (DOPI) by Dummet and Gupta (1964)and VAS for pain. RESULTS There is clinically no significant difference between the Dummet Oral Pigmentation Index (DOPI)and Visual analogue scale for pain between Laser and Scalpel for gingival depigmentation. CONCLUSION Therefore, within the limitation of this study it can be concluded that scalpel technique is still considered the gold standard treatment for gingival depigmentation. KEY WORDS- diode laser, Visual analogue scale (VAS), Dummet Oral Pigmentation Index (DOPI).
