Abstract:Objective: To identify appropriate dimensional items in objective diagnostic analysis for attractiveness of frontal posed smile in Japanese female patients by comparing with the result of human judgments. Materials and Methods: Photographs of frontal posed smiles of 100 Japanese females after orthodontic treatment were evaluated by 20 dental students (10 males and 10 females) using a visual analogue scale (VAS). The photographs were ranked based on the VAS evaluations and the 25 photographs with the highest ev… Show more
“…The minimum sample size for each subgroup (attractive vs. unattractive smile subgroups) was estimated to be 18 according to a previous study . Twenty‐two young Chinese adults (11 males and 11 females; 20–35 years of age) were recruited from the University as raters to assess and rate the sampled smile images.…”

Selection criteria for these raters included: native Han-nationality, no dental-or art-related educational background, and not engaged in dental health services or artrelated jobs.…”

“…The majority of these studies are survey‐based with laypersons evaluating a number of frontal smile photographs modified such that only one research parameter is changed at a time. Only a few studies have explored the influence of multiple factors simultaneously on laypersons' perception of frontal smile attractiveness . In addition, individual and cultural characteristics must be considered in smile evaluation as demographic, racial, ethnic, and cultural differences may play an important part in the perception of smile esthetics .…”

The smile variables of anterior smile line, posterior smile line, upper lip curvature, and smile index are predominant factors of smile attractiveness, which should be given priority to consider and manage in the anterior esthetic treatment plan.

“…Thus, the esthetic enhancement has become the growing reason for dental visits as it has a major role in social interactions. For an orthodontist to provide satisfactory smile corrections, knowledge of esthetics of the human face is necessary (Hata and Arai, 2016).…”
To evaluate the patient perception of orthodontic appliances and their experience during orthodontic treatment. Patient data archived in the institution’s database were reviewed and data pertaining to patients undergoing orthodontic treatment was retrieved. 60 patients were identified randomly. A questionnaire was framed to record the patient's compliance to functional appliance therapy. The questionnaire survey was framed and sent to the patient by sharing the link of the survey planet that consists of necessary context. Chi-square, fisher exact tests were used for data analysis through SPSS software. It was found that patients needed more time to the orthodontic appliance. 66% of patients had eating difficulties, 63.3%. More than half of the patients encountered oral sores almost 57.7%. 64% of the patients using these appliances encountered breakage and displacement problems. A total of 54% of patients stated that they had difficulty in keeping the appliances clean and maintaining proper oral hygiene Individuals undergoing orthodontic treatment had more difficulty to perform routine activities. Care must be taken to overcome these difficulties.
