About
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.
Keywords: Dentine hypersensitivity, desensitizing paste, hydroxyapatite, potassium nitrate.
Full description
Currently, periodontal treatment, both surgical and non-surgical, leaves sequelae in the vast majority of patients. The loss of clinical insertion level could be an early indicator or a possible risk factor for dentine hypersensitivity (HSD) (15). Therefore, it is necessary to correctly diagnose this condition, to achieve a correct treatment of it, which can be performed both in the clinic and at home.
HSD is a condition frequently present in individuals, leading them to seek help from a dentist. It has been described as an 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. (12) To determine the diagnosis and treatment of HSD, it is necessary to deepen the history, the assessment of the patient's pain through a self-assessment system such as the visual analogue scale (VAS), the differentiation between other pathologies using different tools and clinical interpretation, since that the ongoing processes that determine and maintain the opening and permeability of dentinal tubules are still under discussion. Multiple therapeutic modalities are used to manage HSD according to the intensity of pain and patient education, such as the use of remineralizing, desensitizing, blocking, analgesic dentifrices to restorative dentistry therapies, mucogingival surgeries, among others (14).
The research question of this study is: Is the application of a toothpaste based on hydroxyapatite / 5% potassium nitrate / sodium monofluorophosphate 1450ppm nano-crystals more effective compared to the application of a 5% potassium nitrate / fluoride toothpaste Sodium 1426ppm in the treatment of HSD? The general objective is to compare the clinical efficacy in reducing HSD in patients treated with dentifrices based on nano crystals of hydroxyapatite / 5% potassium nitrate / sodium monofluorophosphate 1450ppm and potassium nitrate 5% / sodium fluoride 1426ppm, during an evaluation period 8 weeks The importance of this study lies in the lack of information and quality studies that really assess the effectiveness of the various types of desensitizing toothpastes, so as to be clear about the most effective dentifrices and direct the dentist in the treatment of HSD
