Einfluss zahnmedizischer Vorkenntnisse auf die ästhetische Wahrnehmung der Frontzahnregion

Eye and mouth are involved in the nonverbal communication. How determing teeth can be, can be soonest recognized when they are lost resulting in an old man´s face. Actual dental aesthetic is often in spots preached in white and straight teeth. So the desire for straight white teeth got common. The aim of our study was to determine the aesthetic consciousness of the dental professions and non-dental professions. A total of 214 subjects, 104 without dental professions and 114 with dental professions participated in this study. They were asked to arrange according to their subjective aesthetical sensations maxillary models with different teeth arrangements (without gaps, nested, with gaps), teeth color (B1, A2, A3,5) and gingival arrangement (smooth, individual) and to evaluate this on the base of questionnaires. The same task had to be carried out by using only photos of the same maxillary models. The majority of the interviewees found it easier to decide from the threedimensional models than to decide from two dimensional photos. There is a dependency between the aesthetical awareness of the patients and the level of previous dental knowledge. Subjects non dental professions preferred the brightest color and the straights arrangement against the subjects with dental profession, which favored bright teeth and arrangements without gaps and nested. Furthermore form, color and teeth arrangement of the interviewees had no important effect on the aesthetical sensation. Deductive the desire for dentures which paste well to the rest of the teeth and are not recognized as dentures is supported. To achieve such aims a good and intensive communication between dentists, technicians and patients is necessary. Results of this study point out the preparation of models with the aimed dentures are a good alternative to show the patient the appearance of the planed denture before the beginning of dental treatments.
