Background: The esthetic proportion gauge developed by Chu is using a 78% recurring esthetic dental (RED) proportion and it is based on evaluating the size and proportion of frontal teeth chairside.

Background: The most common dental materials are resin composite direct restorative materials and dentin adhesives, which are marketed with different techniques, application recommendations, and compositions, making it difficult to choose the most suitable material and method for different cases.

Introduction: In our modern society, burnout syndrome develops over a long period of time because of constant stress and increased emotional pressure. Dentistry is known as one of the most stressful professions. The aim of this study was to determine the incidence of burnout syndrome among dentists in Mureș County, Romania, and to assess the determining factors associated with burnout. Material and methods: We conducted an online survey regarding burn-out syndrome among dentists. Results: The most frequent complaint among respondents was the loss of personal accomplishment, followed by emotional exhaustion and depersonalization. Higher levels of emotional exhaustion and depersonalization were seen in non-married, male dentists between 51–60 years, who worked more than 8 hours a day without an assistant. Conclusions: Based on the presented data, the risk factors for burnout syndrome should be brought to the attention of dentists and various preventive programs should be implemented.

Background: Allergy is one of the most widespread diseases in this century. Allergy-causing materials used in dentistry are most frequently metals, such as nickel, cobalt, palladium, and amalgam, certain components of dental composites, denture resin materials, and even certain mouthwash components. The aim of this study was to assess dentists’ experience regarding allergies occurring in their practice among patients and among dental team members.

Background: Measurement-based studies are prone to measurement errors, which occur at the same operator or between different operators during repeated measurements of the same sample.

Background: Epidemiological studies have reported an increasing prevalence of tooth wear, and general dental practitioners see a greater number of patients seeking treatment with worn dentition. Improper oral hygiene, unhealthy habits, occupational hazards, and potentially erosive processed foods seem to play a major role in the non-carious loss of dental hard tissue. The aim of this study is to assess the factors and cofactors that may play a major role in the genesis of dental attrition, dental abrasion, and, especially, dental erosion.

Background: The need for the whitening effects of toothpastes became primary for most users. Changes in the surface roughness of restoration materials after tooth brushing are inevitable, and the abrasion is known to increase the possibility of dental plaque accumulation. Aim of the study: To evaluate in vitro surface roughness changes of different dental restorative materials after tooth brushing simulation. Material and methods: Fifty specimens of two composite materials (Evicrol, Super-Cor), two glass ionomer materials (Glassfill, Kavitan Cem) and a silicate cement (Fritex) were prepared according to the manufacturer’s instructions. Each group of specimens was divided in three subgroups for tooth brushing simulation: using two different types of toothpaste and without toothpaste. Before and after 153 hours of tooth brushing simulation with a custom-made device, the surface roughness was measured with a surface roughness tester. Statistical analysis was performed after collecting the data. Results: All materials exhibited changes in surface roughness after the use of both toothpastes. The self-curing composite showed the less change and glass ionomer materials showed the greatest changes in surface roughness. Conclusions: The surface changes of dental materials depended on their composition and the cleaning procedure. Although self-curing composite was the most resistant to surface changes, its surface roughness values were high. Light-curing composite presented the lowest surface roughness values, even after brushing with toothpastes. The “medium” labeled toothbrush caused significant changes without toothpaste on the surface of light-curing composite, glass ionomer and silicate cement materials.
