Filter by:This study aims to evaluate the effectiveness of different protocols in controlling dentin hypersensitivity in patients with teeth affected by MIH. The subjects will be randomly designated in four experimental groups, according to different treatments. Pain will be assessed with the visual analog scale (Visual Analogue Scale - VAS), after stimulation with air from the triple syringe and and an exploratory probe at the time of (initial) recruitment, immediately after treatment, after 1 week and 1 month, 3 and 6 months after treatment.
Background: Currently, periodontal treatment, both surgical and non-surgical, leaves sequelae in the vast majority of patients, dentine hypersensitivity (HSD) is one of the most important. For this reason, it is necessary to correctly diagnose this condition, to achieve a correct treatment of it. HSD is a condition frequently, which has been described as acute, provoked pain, which is not attributable to any other dental pathology. Its current prevalence is unknown, but it occurs in most patients after their periodontal treatment, and also in healthy patients. Course objective: To compare the clinical efficacy in reducing dentinal hypersensitivity in patients treated with dentifrices based on hydroxyapatite / 5% potassium nitrate / sodium monofluorophosphate 1450ppm and 5% potassium nitrate / 1426ppm sodium fluoride, during a period of evaluation of 8 weeks Materials and methods: A randomized clinical trial will be conducted. Inclusion criteria will be: patients ≥ 18 years, dentinal hypersensitivity in at least one tooth (incisors, canines, premolars) of analogous visual scale ≥4, healthy patients and patients with pathologies, controlled, absence of pathologies that contraindicate participation in the study. Exclusion criteria will include: teeth with extensive or defective fillings, tooth decay and pulpitis, dental crack, unit fixed prosthesis and plural fixed prosthesis, pregnant patients, regular anti-inflammatory treatment, allergy to any of the components of the study, hypersensitivity treatment Recent dentistry Patients will be assigned to two groups. The experimental group (n = 16) will be delivered with hydroxyapatite nanocrystals (VITIS® sensitive) and the control group (n = 16) will be given a paste with 5% potassium nitrate (Sensodyne True White), and after performing an instruction for use on the first visit, four subsequent visits will be made at 2, 4, 6 and 8 weeks after the initial visit. At each visit the hard and soft tissue exam will be performed; and also cold, heat, evaporative and electrical tests will be carried out on the teeth that will be included in the study. The tests will be performed by two previously calibrated researchers, and then the results will be entered into a computer program to perform the effectiveness calculations. Expected results: The results of the present study would demonstrate that there is a general decrease in dentinal hypersensitivity in both groups, during the 8-week study period, presenting a significantly greater improvement in dentin hypersensitivity in either of the two control groups.
