The aim of the present study was to establish the prevalence of sleep/awake bruxism among young students in Transylvania and to correlate the presence of this muscle activity with behavioral variations. This analytical, observational, cohort, cross-sectional, and prospective study involved 308 volunteers aged between 19 and 30 years of different nationalities, all students of the “Iuliu Hațieganu” University of Medicine and Pharmacy in Cluj-Napoca, Romania. Subjects were asked to complete an anonymous questionnaire which was structured in five sections. The results obtained from the questionnaires were analyzed separately for sleep bruxism and for awake bruxism. We did not find any statistically significant correlation between awake bruxism or sleep bruxism and age (p = 0.30 and p = 0.37, respectively), sex (p = 0.44 and p = 0.48, respectively), or nationality (p = 0.55 and p = 0.67, respectively). Only a high degree of stress and frustration (p = 0.035 and p = 0.020) was observed in European subjects except for the Romanians and the French, likely related to the difficulties of adapting to the language and lifestyle in Romania. Female sex was statistically significantly associated with an increased level of stress (p = 0.004), duty-related depression (p = 0.006), and duty-related anxiety (p = 0.003). Stress and anxiety can be favorable factors in the appearance of both types of bruxism; however, depression is associated only with awake bruxism.

Aims and Objectives. The objectives of this study are the comparaison of survival rate of feldspathic and pressed lithium-disilicate ceramics veneers, survival analysis, failure types, clinical factors that may influence their lifespan in a Romanian study group. Materials and methods The materials used were VITA VM7 (VITA Zahnfabrik, Germany) and E.max (Ivoclar Vivadent AG, Liechtenstein). Patient demographics, treatment and any subsequent failure dates were recorded. 170 patients with 507 veneer-treated teeth were divided into 2 groups: patients with and without therapeutic failures. Results 48 veneers failed. Most failures were fractures (35.36%), followed by debonding and chipping. The most affected veneers in general were the feldspathics (19.9%) compared to lithium disilicate (8.8%) at 10 years. Conclusion Regardless of their superior aesthetics, feldspathic veneers are less mechanically resistant than pressables, but other clinical parameters must also be considered such as the age of the prosthetic rehabilitation or the number of teeth involved. Since study results are consistent with current literature data, Romanian patients can be considered in the international context of veneer treatments.
