Keywords:
incisor display, orthodontics, smile, smile analysis, smile arcAbstract
The aim of this study was to assess and evaluate the awareness and knowledge of smile arc and analysis among orthodontists and non-orthodontists by means of conducting a knowledge, attitude and practices survey. A closed questionnaire of 17 questions was prepared in consultation with experts involved in the training of dentists. Based on a pilot study a response count of 130 was determined to achieve a power of 80. The questionnaire was shred through professional chat forums. A reminder post was shared two weeks after the initial post. The survey was closed four weeks after the reminder post and 145 responses were obtained. Most respondents were non-orthodontists and were young practitioners with experience of less than 5 years. Descriptive statistics showed that most respondents are aware of smile analysis and smile arc but most respondents do not use it in practice for diagnosis and treatment planning. Independent t-test showed that orthodontists are more aware of smile arc and smile analysis and use it more often in clinical practice when compared to non-orthodontists. Most participants are aware of the parameters for to be evaluated for smile analysis and smile arc.
