“…The test participants with extensive experience in shade assessment were far more accurate when selecting shades than general dental practitioners. Other authors found no relationship between experience and accuracy of shade matching [2,3]. Although the difference in clinical experience among our students was not extensive, a detailed analysis of the obtained data showed that the students of dental technology would more often assess filling shades in the correct way, thereby producing fewer incorrect answers.…”

“…It has been observed that slight differences in saturation (chroma) and hue are less effectively captured by the human eye than mistakes in the correct determination of brightness [3]. Brightness is a critical component which ultimately affects the proper selection of the filling [6].…”

“…In the following part of the study, the students identified the shades of Herculite XRV fillings in 5 extracted teeth using the VITAPAN Shade Guide. The decision time was limited to one minute for each filling [3,5]. The students made a total of 370 choices.…”

“…The studies published have been unable to conclusively determine whether the examiner's experience is important for the efficacy of shade assessment. Given the conflicting reports in this respect, this topic requires further research [2][3][4]. Independent work and the patient's aesthetic requirements are therefore a great challenge for students and, then, doctors.…”

The everyday work of a dentist requires the skill to properly select a filling or a prosthesis shade. Moreover, the development of adhesive techniques and the increasingly wide range of composite materials available expand the array of procedures where these abilities prove useful. Students of dentistry and dental technology are trained in the structure of teeth, the properties of materials and their shades. They are all important parts of preclinical education. New devices help dentists choose shades in their dental practice, but the selection of a filling shade is still almost always based on visual perception; and it is the result of cooperation between a doctor and a dental technician. Such cooperation brings about the best aesthetic results. However, practical verification of these skills takes place at a dental chair with a patient sitting in it.The choice of a shade is affected by several factors, among others by the individual predispositions of the doctor. This includes the red-green vision disorder (color blindness). As candidates for AbstractBackground. In the course of their training, students of dentistry and dental technology learn the structure of teeth and their shades. These are important parts of preclinical education. Objectives. The aim of this study was to evaluate if the ability to identify the shades of composite fillings depends on the field of study (dentistry and dental technology) or on the sex of participants, and indirectly assess whether dental students need support during this procedure. Material and Methods. The study involved a group of 74 students of the second year of dentistry (33 women and 19 men) and dental technology (20 women and 2 men). The students identified the shades of A1, A2, A3, C1 and C2 Herculite XRV ® fillings in 5 extracted teeth. Results. There was no statistically significant difference in the ability to identify the filling shade between the students of dentistry and the students of dental technology (p = 0.303). A difference was found in the correct identification of filling shades between men and women (p = 0.04996). The ability to correctly determine shades changed depending on the filling shade in a tooth and ranged between 13% and 82%. Conclusions. The ability of dentistry and dental technology students to match a shade of a restoration to a shade of a tooth is affected by sex but not by the students' field of study. (Dent. Med. Probl. 2016, 53, 3, 394-400).

Visual shade matching has remained a skill acquired through clinical experience. The purpose of this study was to evaluate the shade matching ability of dental students as they progress through their education. Sixty-five students, representing four levels of experience by year enrolled in dental school, participated in this study. Students were given a preclinical shade tab matching task. They were also asked to choose the best shade match for a natural tooth in each of three patients. The natural tooth shade matching task was designed to have simple, moderate, and complex cases to match. The frequency of correct answers was compared across samples across the four levels of fundamental tab match ability and clinical experience. On average, 51 percent of the students were able to match the correct shade tab in the matching task in a bench setting. For the natural tooth color matching task, 49.2 percent of the students selected the clinically acceptable color matched shade tabs (DE*≤2.69). Although there was no statistically significant difference across the levels of fundamental ability and experience, rates of correct answers for natural tooth color matching progressively improved for the complex case from year 1 to year 4. This study reveals that, for complex cases, education and knowledge of color science combined with clinical experience improve students' ability for color matching in a clinical setting.

The purpose of this study was to evaluate the use of the Toothguide Training Box (TTB) for training dental students in color identiication. The seventy-four volunteers who took part in the study attended a seminar on the Vita 3D Master Guide (MG) and the TTB system as well as a demonstration of the equipment before training began. At the end of the training they took the TTB inal test. In addition, the participants were asked to recognize ten MG shade tabs in a blind manner before and after TTB training. The training times and percentages of correct answers were compared using the paired t-test. Variations in scores with training times and percentages of correct answers before and after training were compared using the ANOVA test. Training times between thirty-one and thirty-eight minutes provided a signiicantly higher mean score than training times of over thirty-eight minutes (p=0.036). The percentage of correct answers obtained with the MG before and after training shows a positive correlation. High TTB scores are associated with a greater number of correct answers in MG shade tab selection.
