As we are into the evidence-based paradigm shift a decade back it would be interesting to know the current concepts and updates in evidence-based orthodontics, especially in the area of patient-centered orthodontics.
Patient centered orthodontics has been validated by many studies particularly those which have evaluated the relationship between this concept and the quality of life of orthodontic patients. In a study which our team carried out a few years ago on dental aesthetics and oral health related quality of life in young adults, we found out that self-perception of dental aesthetics using the IOTN had significant impacts on the OHRQoL of the respondents. This was assessed using both the Oral health Impact Profile (OHIP) and an Orthodontic specific Quality of life measure :the Psychosocial Impact of Dental Aesthetics Qustionnaire (PIDAQ). The findings of our study were published in the AJODO and the full text is available here on Research gate as 'Dental aesthetics and oral health-related quality of life in young adults' by Isiekwe et al.
In the near future, patient centered orthodontic measures and assessments, will be the major consideration for orthodontic treatment planning.
i think recent studies are better carried out than those made in previous years. Quality is improving, but at the moment the starting point are the cochrane reviews abour orthodontics.
