Objective: This study evaluated alveolar preservation using leukocyte-platelet rich fibrin (L-PRF) in adult patients, comparing it to control alveoli. Methods: Conducted from 2016 to 2018, the study included 17 adult patients, aged between 20 and 45 years, diagnosed with either Class I or Angle Class II-1 malocclusion. Participants underwent first premolar extractions, with L-PRF treatment applied to one side of their mouth, while the other side served as a control. This retrospective study compared tomography data from these patients, who also underwent maxillary canine retraction. One side of the mouth was treated as an experimental alveolus, preserved with L-PRF, and the other as a control. Data normality was assessed using the Shapiro-Wilk test. The Wilcoxon test was used for group comparisons, and the McNemar test was applied to fenestrations. Results: No statistically significant differences were observed in root length changes and surrounding bone tissue between the two sides (P > 0.05). Conclusion: The study found no significant differences in root length reduction and changes in supporting bone tissue between the experimental and control sides. This suggests that alveolar preservation with L-PRF does not alleviate the deleterious effects observed during maxillary canine distalization.

Abstract The attire and appearance of health care professionals play an important role in shaping patients' perceptions of their professionalism, confidence, and credibility. In the era of social media, where image and visual presentation are highly valued, one might question whether details such as the color of laboratory coats have changed. This study aimed to evaluate patient preferences regarding dentists' attire and its impact on their confidence and perceptions of professionalism. Additionally, the study explored gender-based differences in these responses. A total of 73 participants (38 males and 35 females; mean age 20.18 years) were enrolled. Participants were presented with images of male and female dentists wearing laboratory coats and scrubs in six colors (white, dark blue, light blue, gray, black, and green) and their visual attention was tracked using The Eye Tribe tracker and OGAMA software. Following the eye-tracking session, participants completed a questionnaire on the importance of a dentist's appearance, attire preferences, and color preferences using visual analog scale. Data were analyzed using SPSS (v.25) with descriptive statistics, Student's t-test, Pearson's chi-squared test, and validation tests (Kaiser–Meyer–Olkin = 0.682, Bartlett's p < 0.001). Participants preferred white attire (40%) over other colors, with dark blue and light blue following. Younger participants showed some interest in nontraditional attire, though white remained dominant. Gender differences were observed; females were more likely to feel uncomfortable with a dentist's attire (17.1%) compared with males (2.6%; p = 0.035). Both genders favored laboratory coats over scrubs, but no significant differences were found regarding attire preferences (p = 0.352). Traditional white attire remains the preferred choice among participants, reflecting professionalism and trust. However, gender differences in discomfort with attire suggest the need for tailored approaches in clinical settings. These findings may also have implications for social media, where the digital representation of health care professionals could shape patient expectations and preferences.
Influence of Lipstick Application on the Attractiveness of Smile in Women With and Without Malocclusions: An Eye‐Tracking Study
(Wiley, 2025) Gil Guilherme Gasparello; Mohamad Jamal Bark; Giovanna Purkote Yamaguchi; Rosilene Andréa Machado; Joel Suárez; Orlando Motohiro Tanaka
Malocclusion significantly impacts visual attention and attractiveness perception, with the mouth being the primary focus. While lipstick influences attention dispersion, it does not shift the main focus from the mouth. Heat map analysis confirmed that the mouth area remains the primary focus across all images, regardless of lipstick use.
