The article presents the results of a study to determine the color of the central incisor on the upper jaw. Traditionally, the choice of the color of this tooth is the most difficult and controversial. Color determination was carried out by hardware (Vita Easyshade Advance 4.0) and visual methods, which were attended by students of SamSMU aged 19 to 22 years. The obtained results say that it is preferable to use the hardware method based on the digital perception of the object under study and adapted to the generally accepted color scale; this method minimizes the requirements for color determination criteria, is a high-tech and convenient solution in the daily practice of a dentist.

Shade matching is a challenging step and the major objective in esthetic and restorative dentistry. On many occasions, the production of the accurate target color will not be achieved due to errors in the registration of the target color, or errors in composing the appropriate color of the restoration in the dental laboratory. Thus, the accurate and correct shade matching of tooth and restoration is one of the most important quality criteria for the patient and the key to successful results for the dentist. Conclusion: Spectrophotometers, colorimeters, intraoral scanners, and imaging systems are useful and relevant tools for tooth color measurement and analysis, and for the quality control of color reproduction. The combination of visual and instrumental methods of tooth color determination will complement each other, leading toward predictable esthetic results.

Background. The etiology of nocturnal enuresis (NE) is multifactorial and has not been fully explained yet. New ways of treatment are constantly being investigated, including the rapid maxillary expansion (RME).Methods. A total of 41 patients diagnosed with NE were divided into two experimental groups: A and B. Group A included 16 children who have been treated with RME. Group B comprised 25 children who have not undertaken orthodontic treatment. Children from both groups have been monitored in monthly intervals, during a 12-month period, towards the intensification of NE. The comparative analysis of both groups has been conducted after 3 years of observation.Results. Statistical analysis has shown a 4.5 times increase of the probability of reduction of NE in the case of the treated group in comparison with the group of children who have not undergone orthodontic treatment. Unfortunately, the chance of obtaining total dryness diminished proportionally to the higher degree of intensification of enuresis at the beginning of the test.Conclusion. RME can constitute an alternative method of NE treatment in children, irrespective of the occurrence of upper jaw narrowing.
