Laser USP test for the prevention of root caries

The use of laser for the prevention of root caries (the root of the teeth) has been successfully tested in research in the Faculty of Dentistry of Ribeirão Preto (FORP) USP. The technical work of the experienced dentist César Lepri allows preventing caries with minimal intervention, as currently happens with fluoride application. The method can avoid the need to perform restorative treatment on teeth.

The aim of the study was to evaluate the effectiveness of the laboratory parameters of laser irradiation in the treatment of prevention of the development of root caries lesion formed in high risk caries, analyzing the influence of the type of laser used with or without the fluoride. The root caries lesion is considered a major cause of tooth loss in adults, and the problem worsens with age.

This fact is due to exposure of the roots, periodontal disease or even naturally, a diet that favors their formation, difficulty of cleaning, and chronic health problems that reflect the reduction of the quantity and quality of saliva, explains Professor Regina Guenka Palma-Dibb, FORP, who supervised the research. The root caries affects approximately 40% to 60% of the adult population.

Currently, the treatment is done with drill and aesthetic restoration material normally. Prevention is currently made only with application of fluoride and control of dental plaque (biofilm), says the teacher.

According to Regina, the laser can be employed to prepare the tooth in place of the drill little engine and causing less discomfort to the patient and performing restoration with the same materials. However, the laser has also been used in an attempt to control the development of caries and so reduce the need for restoration.

The laser has been used in clinical studies in prevention of caries in enamel, with promising results. There is no need for reapplication in short time as with the conventional method, which consists of topical fluoride application, says the teacher. Laboratory tests on root caries also had favorable results, but the clinical use of the technique depends on further studies.

The laser has been widely used in dentistry, especially in situations that we need to act in dentin hypersensitivity treatment of oral lesions, the pain caused by TMJ problems or trauma (surgical or not), for herpes, surgery for soft tissue as anti-inflammatory and phototherapy. In these situations the laser demonstrates efficacy and a very large facility of application and patient acceptability, says Regina.

For the preparation of teeth and caries prevention, the laser has already been used, but still without much intensity due to use different equipment having a higher cost. Many lasers is not approved by the National Agency for Sanitary Surveillance (ANVISA) for use in private practice, says Professor FORP. Its use is feasible and patient acceptability is better than conventional treatment, since it causes less discomfort, because it generates less noise, vibration and often does not require application of anesthesia when your job.
