Abstract

Orthodontics plays a role in an individual’s appearance which can affect the perception of others that can vary greatly depending on their educational and social economic background. Objective: To determine if there were differences between dentist’s and non-dentist’s perceptions on facial attractiveness with normal occlusion and various types of malocclusions in Indonesian population. Methods: A cross sectional study was conducted on 80 dentists and 80 non-dentists aged 23-49 years old. The perceptions differences between groups were assessed using visual analogue scale on ten photographs for each gender that have been digitally manipulated. Mann Whitney test was used to analyze the differences. Results: Normal occlusion is the most attractive condition for dentists and non-dentists. There are significant differences between dentist’s and non-dentist’s perceptions of facial attractiveness showing normal occlusion, increased overjet, increased overbite, reduced overjet, reduced overbite, mild crowding, open bite, and reversed overjet malocclusions (p < 0.05). Whilst both groups agreed (p > 0.05) that severe and moderate crowding were the least attractive malocclusion. Conclusion: Regarding the facial attractiveness, dentist’s and non-dentist’s perceptions are significantly different for most malocclusion types. However, there is an agreement that severe and moderate crowding are the most disturbing malocclusion that have a considerable effect on facial attractiveness.

Abstract

Objective: This study aims to investigate the effectiveness of ultrasonic tip with and without solvent in removing gutta-perca and bioceramic sealer from the middle and apical third of the root canals. Methods: This is a true experimental study with randomized pretest-posttest control group design. Eighteen freshly extracted straight single-rooted mandibular first premolars were confirmed by CBCT and selected. The teeth were decoronated until a length of 16 ± 0.5mm. The teeth were prepared and obturated using gutta-percha and bioceramic sealer with a hydraulic condensation technique. Pre-instrumentation CBCT imaging of all teeth was carried out to obtain the initial volume of the obturation material. After incubating for 30 days, the treated teeth were randomly divided into three groups (n = 6): ultrasonic and xylene, ultrasonic and orange oil, and ultrasonic only. Post-instrumentation CBCT was carried out and the amount of obturation material removed was calculated using CT Analyser. The two-way ANOVA was used to determine the solvent and location interaction. Results: The results showed that there was no significant difference among the groups based on the treatment and location (p > 0.05). In addition, no significant interaction was found in relation to the cleanliness of the root canal (p > 0.05). Conclusion: There was no difference in the effectiveness of ultrasonic obturation material cleaning with and without endodontic solvents. Based on the results, the obturation material with the most residue is a sealer.
