Filter by:Visual shade matching is the most common method, in which a color standard from a commercially available dental shade guide is compared to and matched with the target tooth. However, several factors can contribute to perception errors including: different lighting variables, multiple shade systems available in the market with lack of standardization in color systems and corresponding porcelain systems, individual human variables in color perception and lack of understanding of color science. Therefore, in order to eliminate the uncontrolled variables during the color matching process, instrumental methods have been developed. Spectrophotometric measurement methods employing computer calculations, based on color science and theories, allow quantitative evaluation which is objective and appears to be more accurate. However, extremely high costs, relatively low performance with respect to agreements of the computer-aided devices, and edge loss error make it less acceptable. One of the most powerful tools in communicating with both patients and dental ceramists is digital photography. Hence, this study is designed to explore the possibilities of a novel approach to shade management (eLABor_aid) utilizing a photocolorimetric (PCM) method and subsequent shade formulation without the use of stock shade guides in comparison to well-known visual and instrumental methods. The aim of the study is to evaluate the accuracy of digital photography combined with shade analyzing software (eLAB) in optimizing shade matching when compared to conventional and instrumental methods of shade selection. A Null Hypothesis is suggested where no significant difference regarding shade selection between eLAB protocol, conventional and instrumental methods will be found.
The aim of this research was to assess the impact of Oral Health-Related Quality of Life (OHRQoL) on children and their families affected by Traumatic Dental Injury (TDI) after insertion into a Dental Trauma Care Program (DTCP). After a sample size calculation, this non-randomized clinical study was composed of a consecutive sample of 2 to 6-year-old children registered in the DTCP from 2012-2019. Parents/Caregivers were interviewed to fill up an OHRQoL questionnaire. The Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS) was applied (in form of an interview) to evaluate the impact of TDI on OHRQoL before, and after treatment. The scores of the B-ECOHIS were calculated using the additive method, summing the numeric response codes for each item. The Andreassen classification was used to determine the TDI. The patients were treated (minimally intervention/invasive intervention) according to TDI severity (uncomplicated/complicated). The Kolmogorov-Smirnov test was performed to evaluate the normality of the data to determine the use of parametric or non-parametric tests. Mean or median comparisons were made for items in the overall scale and subscale scores to compare B-ECOHIS total scale/subscales/domains before and after insertion in DTCP. The responsiveness was assessed by analyzing the change in the scores on the scales and subscales. The changes were calculated by subtracting the post-treatment scores from the before-treatment scores. Positive change scores indicate an improvement in OHRQoL, while negative scores indicate deterioration. TDI severity and treatment-associated were also evaluated.
