Abstract

Ten years ago, Chalmers and Glasziou pointed out in the Lancet that 85% of all biomedical research was being avoidably wasted because of imbalanced research question/outcome selection, as well as poor study design, execution, and reporting. According to findings of recent “research on research” studies, a high level of such kind of avoidable waste should also exist in orthodontic research. This warrants efforts to improve each stage of the research production and reporting process.

Nowadays, patients' psychosocial function is considered a core element of oral health. Also, their treatment needs and preferences have formed a main component of evidence-based dentistry. Therefore, to achieve shared decision-making, orthodontists need to have an adequate understanding of each patient's values and perceptions.

In this context, orthodontic research should be patient-centered so that the knowledge and perception gaps between clinicians and patients can be reduced, and research evidence that is suitable for patients to understand can be provided. In addition, patient-centered outcomes that can reflect patients' perceptions and psychosocial status should be widely used.

However, recent scoping reviews have shown that during the past decade, patient-centered outcomes including those regarding adverse effects, health service resource utilization, and quality of life have remained under-represented in orthodontic trials. Thus, the use of dental patient-reported outcomes and dental patient-reported outcome measures should be promoted to facilitate the provision of a patient-centered evidence base, reduce the avoidable waste related to research question/outcome selection, and thereby increase the value of orthodontic research.

Avoidable Waste in Orthodontic Research

Just ten years ago, Chalmers and Glasziou1 pointed out in the Lancet that a majority of all biomedical research was being avoidably wasted because of imbalanced research question/outcome selection, inadequate study design and execution, nonpublication, lack of accessibility, and poor reporting. Because more than 50% of studies failed to take adequate steps to reduce biases (eg, inadequate allocation concealment),2 more than 50% of studies were never published in full,3 and more than 50% of

Patients' Perceptions and the Definition of Oral Health

Recognition of the importance of patients' perception can be traced back to the addition of “social well-being” into the World Health Organization definition of health in 1940s, which led to a paradigm shift in the model of health from biomedical to biopsychosocial.12 Thereafter, similar modifications were made to the definition of oral health. In 1993, Dolan13 defined oral health (for older populations) as “a comfortable and functional dentition which allows individuals to continue in their

Evidence-Based Medicine and Evidence-Based Dentistry

A common criticism of evidence-based medicine (EBM) has been that EBM means “cookbook medicine” and decision-making based on evidence alone, without necessary deliberation and reasoning.15 However, as experts in EBM16 and evidence-based orthodontics17 have pointed out, such an argument is merely a misunderstanding of what EBM is. In effect, the need to consider each patient's values has been aggressively promoted since the very early years of EBM.16

In 1996, Sacket et al. 18 already stated,

“EBM

SDM in Orthodontic Practice

According to Gatellari et al,23 SDM is a decision-making process in which clinicians and patients are equal partners and are required to exchange information and preferences to negotiate a mutually acceptable treatment decision. In the case of orthodontics, this approach is particularly important for many reasons. Some of the main ones are as follows.

First, as malocclusion is not a disease but a variation from the societal norm,24 orthodontic treatment is often elective.25 In addition,

Patient-Centered Research and Patient-Centered Outcomes

The ultimate goal of all medical research is to improve our knowledge underpinning the prevention and treatment of illness.34 In the context of EBD, dental studies should be designed, executed, and reported properly so that their findings are relevant, valid, and useable, facilitating the achievement and development of patient-centered, evidence-based dental practice. Toward this end, the research questions of dental studies should be relevant to patients, and the outcomes that they use should

dPROs and dPROMs

dPROs, a term recently coined by John,40 are defined as “any report of the status of a patient's oral health condition that comes directly from the patient, without interpretation of the patient's response by a clinician or anyone else.” Similar to oral health being a component of general health, dPROs are a subset of all patient-reported outcomes (PROs). dPROs can capture the impact of conditions or interventions on oral health, while dental dPROMs are used to assess this impact and express it

OHRQoL and Orthodontic Research

As mentioned previously, OHRQoL is a major dPRO, and each OHRQoL instrument can be seen as a dPROM or a combination of several dPROMs (depending on the number of dimensions the instrument contains).41 During the past twenty years, orthodontic researchers have carried out many epidemiological studies regarding OHRQoL.45 Based on these, recent systematic reviews have concluded that malocclusion has a significant (although small) negative impact on the OHRQoL of children (mainly in the emotional

Summary

Patients' psychosocial function is a core element of oral health; their treatment needs and preferences form a main component of EBD. However, recent studies have shown that most of the outcomes measured in orthodontic trials are focused on assessing morphologic changes, whereas patient-centered outcomes have remained under-represented. In light of this, the use of dPROs and dPROMs should be promoted to facilitate the provision of a patient-centered evidence base, reduce the avoidable waste
