AIM: The aim of the study was to evaluate the efficacy of the professional bleaching treatment with Pola Office (SDI): the shade, chroma and value parameters of the anterior upper elements were analysed. METHODS: At the Prosthetic Unit of the Modena and Reggio Emilia University, 10 patients were selected. All patients underwent oral hygiene treatment and spectrophotometric analysis (Spectro-Shade) of the 6 front elements: the variables L (value), c (chroma), and h (shade) were examined in the cervical, mesial and incisal sections. Spectrophotometric analysis was repeated 6 months after initial bleaching. The patients were asked to report the degree of sensitivity after 3, 6, 12 and 24 h and after 3, 6, 7, and 10 days. RESULTS: The value (L) of the treated elements increases after bleaching, the chroma parameter (c) showed lower values than those prior to treatment (except for the first patient); this means a shift towards a lower degree of saturation. The course of the shade parameter is uniform and constant for all patients, with a shift towards yellow chroma values. Postoperative sensitivity was confined to the first 3 h after treatment, after which it showed a steady decrease over 24 h. CONCLUSIONS: Esthetic results obtained using the Pola Office bleaching procedure were visibly significant; confirmed by colorimeter analysis. The harmony between chroma, shade and value remained 6 months after the bleaching treatment; the sensitivity is particularly high in the first hour, however after 24 h sensitivity is greatly reduced.Denti discromici possono essere oggetto di trattamenti cosmetici, soprattutto se in zone altamente estetiche, come le zone anteriori.Lo sbiancamento interno rappresenta un metodo alternativo alle comuni tecniche invasive come faccette e corone.Lo sbiancamento denti denti vitali può essere effettuato ambulatorialmente oppure attraverso apposite mascherine notturne utilizzando gel a base di perossido di carbamide1-4.

Abstract

AIM: The aim of the study was to evaluate the efficacy of the professional bleaching treatment with Pola Office (SDI): the shade, chroma and value parameters of the anterior upper elements were analysed. METHODS: At the Prosthetic Unit of the Modena and Reggio Emilia University, 10 patients were selected. All patients underwent oral hygiene treatment and spectrophotometric analysis (Spectro-Shade) of the 6 front elements: the variables L (value), c (chroma), and h (shade) were examined in the cervical, mesial and incisal sections. Spectrophotometric analysis was repeated 6 months after initial bleaching. The patients were asked to report the degree of sensitivity after 3, 6, 12 and 24 h and after 3, 6, 7, and 10 days. RESULTS: The value (L) of the treated elements increases after bleaching, the chroma parameter (c) showed lower values than those prior to treatment (except for the first patient); this means a shift towards a lower degree of saturation. The course of the shade parameter is uniform and constant for all patients, with a shift towards yellow chroma values. Postoperative sensitivity was confined to the first 3 h after treatment, after which it showed a steady decrease over 24 h.
