Abstract The objective of this study was to compare the efficacy of fluoride varnish (Fluorniz(r)) and irradiation with a gallium-arsenide-aluminum diode laser in the treatment of cervical dentin hypersensitivity. Cervical dentin hypersensitivity (CDH) is a painful condition that is highly prevalent in the world's adult population, with one in six patients presenting this symptom. Eighty-six teeth were divided into two groups: Group 1, teeth treated with Fluorniz; Group 2, teeth irradiated with a GaAlAs laser at a 4 J/cm2 dose. The two treatments were applied to the buccal cervical region in four sessions, at intervals of 72 to 96 h. The response of the patient to tactile and thermal-evaporative stimuli was rated on a visual analog scale. The results showed a reduction of hypersensitivity in response to tactile and thermal-evaporative stimulation at the end of treatment in both groups. In conclusion, short-term treatment with Fluorniz was found to be more effective than low-level laser radiation in reducing cervical dentin hypersensitivity.

Spinal Cord Disorders

Background: The problem of protecting and maintaining health of workers in the microelectronics industry exposed to adverse occupational factors including tension and overstrain of the muscles of the upper extremities and visual strain, gains special relevance. Objective: Introduction of the developed and patented low-level laser therapy techniques to recover functions of vision and the musculoskeletal system impaired in the course of work. Materials and methods: The study involved 65 chip assemblers aged 26–41 years. Their eyes, the back of the hands, and the collar area were exposed to low-level laser radiation from the red region of the spectrum. All employees were examined by a neurologist and a surgeon and their working conditions were evaluated. The accommodation apparatus was tested using an AKA-01 type accommodation meter. Results: After five 10-minute sessions, we registered an increase in the volume of absolute accommodation during the observation period before and after the work shift by 28 % and 19 %, respectively. On subsequent days of observation, we noted an increase in the accommodation during 10 days, followed by a decrease by the 30th day of observation. Application of preventive techniques helped eliminate spinal cord disorders in all workers. Blood circulation in fingers increased by 66 % compared to the initial condition. Discussion: Low-level laser therapy improves blood supply, intensifies redox processes in the retina of the eye, skin cells, and blood vessels. Conclusions: Low-level laser radiation of the red region of the spectrum relieves the spasm of accommodation and normalizes the efficiency of the accommodation apparatus. Such laser therapy helps eliminate spinal cord disorders and improve blood circulation. Introduction of the developed techniques can prevent occupational diseases and reduce disability in patients.
