Seguridad, eficiencia y estabilidad de color del blanqueamiento vital nocturno a base de peroxido de carbamida al 10% con carbacol en dientes con coloraciones anormales de pacientes atendidos en las clínicas odontológicas de la USTA

Abstract

Abnormal colorations are perplexing for the dentist and frustrating for the patient. On the one hand, patients want immediate treatment and, on the other, the professional must carefully weigh the clinical variables such as the large pulp chambers typical of young teeth, the dentinal condensation of older teeth, and the unpredictable gingival response. Teeth whitening with 10% Carbamide Peroxide has increased since it was first reported in 1989 by Haywood Heymand. Woderton reported that 10% Carbamide Peroxide was no more toxic than dental cements, mouthwashes, or toothpaste when applied to animal tissues. Haywood et al. used photomicrographs to show the tooth surface treated with Carbamide Peroxide did not differ from the untreated control surface. The purpose of the study was to assess the advantages of the vital bleaching technique and to observe the time and amount of material used to achieve a normal (or desired) coloration. It was also determined which abnormal colorations responded best to treatment and maintained stability. in the color obtained and thus measure the effectiveness of the treatment. To determine the safety of the treated dental surface with the help of the scanning electron microscope, its chemical composition was determined using the atomic absorption spectrophotometer and the ionic liquid chromatograph. For this study, the home application whitening technique (Opalescence) manufactured by Utradent-Products Incorporated (USA) prescribed and supervised by the dentist was used, with which a 10% Carbamide Peroxide-loaded splint is used with a Carbapol and PH 6.5 which breaks down into 3% Hydrogen Peroxide and 7% Urea Peroxide. In a review of the medical and dental literature, Feinman et. al, described the physiological mechanisms of dental whitening products, including Carbamide Peroxide. They concluded that teeth are permeable to fluids, especially in spaces accepted and desired by patients.
