Effect of an orthodontic resin modified with silver-nanoparticles on enamel color change
2021
Background: To evaluate the effect of an orthodontic resin modified with various concentrations of silver-nanoparticles (AgNPs) on enamel color. Material and Methods: Twenty lower premolars were collected and divided into four groups (n = 5) according to the concentration of AgNPs (0.05%, 0.1%, 0.5%, and 1% wt/wt). Additionally, a group bonded with a conventional resin was used as control (n=5). Previous to the bracket bonding, enamel color was measuring with a spectrophotometer. Specimens were stored for 6 months in deionized water. Brackets were debonded and color changes of enamel were calculated with the CIEDE 2000 formula (ΔE00). One-way ANOVA and Tukey test were used to assess the col…
Analysis of the association between facial biotype, overbite and overjet in the permanent dentition
2023
To determine the association between the facial biotype, the overbite and the overjet in digital lateral skull radiographs. MATERIAL AND METHODS: 230 digital skull lateral radiographs of patients with permanent dentition with 18 to 55 years old were used as sample. The VERT index and the Ricketts analysis were considered to identify the facial biotype, overbite and overjet. RESULTS: The facial biotype with the highest prevalence was dolichofacial with 36.52% (n=84), being more frequent in the female sex. However, the mesofacial biotype predominated in the male sex. On the other hand, the normal overbite presented the highest percentage with 66.08% (n=152) and the deep bite was more frequent…
