Body dysmorphic disorder, often referred to as BDD, is a mental health condition characterized by an intense preoccupation with perceived flaws in physical appearance that are either minor or not observable to others. These concerns can lead to significant distress and impairment in daily functioning. In the realm of dental and orthodontic care, where aesthetic improvements to teeth and facial structure are central to treatment, understanding the intersection between BDD and the perceived or objective need for orthodontic intervention becomes particularly important.
Orthodontic treatment need is typically evaluated using standardized indices such as the Index of Orthodontic Treatment Need (IOTN), which includes dental health component (DHC) and aesthetic component (AC), as well as the Index of Complexity, Outcome and Need (ICON). These tools help clinicians determine the severity of malocclusion and prioritize cases based on both functional and aesthetic criteria. A recent systematic review published in the Journal of Personalized Medicine examines the existing evidence on how BDD relates to these measures of treatment need.
Understanding Body Dysmorphic Disorder in Clinical Contexts
BDD affects approximately 1.7 to 2.4 percent of the general population, though rates appear higher in settings focused on appearance enhancement. Individuals with BDD often experience intrusive thoughts about their looks, engage in repetitive behaviors like mirror checking or excessive grooming, and may seek multiple consultations with specialists in pursuit of correction. When these concerns center on the teeth, jaws, or smile, patients frequently turn to orthodontists or cosmetic dentists.
The disorder is distinct from normal dissatisfaction with appearance. It involves a level of obsession that can interfere with work, relationships, and mental well-being. Comorbid conditions such as anxiety, depression, or obsessive-compulsive disorder are common. Early recognition by healthcare providers, including those in higher education dental programs, can guide appropriate referrals to mental health professionals rather than immediate pursuit of irreversible procedures.
The Role of Orthodontic Treatment Need Assessment
Clinicians rely on objective tools to assess whether a patient would benefit from braces, aligners, or other interventions. The IOTN-DHC focuses on dental health implications like crowding, spacing, and bite issues, while the AC emphasizes visual appeal from the patient's or clinician's perspective. ICON incorporates complexity and outcome predictions alongside need.
These indices help ensure treatments address genuine functional or health concerns rather than purely subjective desires. However, when psychological factors like BDD are present, even objectively minor issues can dominate a patient's thinking. This creates challenges in determining true treatment necessity and predicting satisfaction post-intervention.
Key Insights from the Systematic Review
The systematic review by Tsaprazlis and colleagues synthesized available studies exploring the association between BDD and orthodontic treatment need. Researchers searched multiple databases and included prospective studies that used validated BDD screening tools alongside established orthodontic indices.
Findings revealed an inconsistent relationship overall. Two studies employing the IOTN-DHC reported a negative association, meaning individuals with higher BDD symptoms sometimes showed lower objective treatment need. In contrast, investigations using IOTN-AC or ICON found no significant link. Associations involving factors such as sex, age, education level, depression, and anxiety also varied across the included research.
The review authors emphasize that current evidence remains preliminary due to the limited number of studies and potential biases in existing data. They highlight the importance of personalized assessment approaches in orthodontic decision-making rather than relying solely on any single metric.

Implications for Orthodontic Practice and Patient Care
Orthodontists encounter patients with elevated BDD prevalence compared to the general population, with estimates in cosmetic dental settings ranging from around 5 to 13 percent in various studies. This underscores the need for thorough psychological screening during initial consultations.
Practical steps include incorporating brief validated questionnaires for BDD into routine assessments. Clinicians should explore patient expectations, history of previous treatments, and any signs of excessive preoccupation. When red flags appear, collaboration with mental health experts becomes essential to avoid unnecessary interventions that may not resolve underlying concerns and could even worsen distress.
Successful management often involves interdisciplinary teams, ensuring both aesthetic goals and psychological well-being are addressed. This approach can reduce risks of patient dissatisfaction, treatment dropout, or repeated consultations.
Relevance to Higher Education and Dental Training
University dental schools and orthodontic residency programs play a vital role in preparing future professionals for these complex cases. Integrating education on mental health screening, BDD recognition, and ethical decision-making into curricula equips graduates to handle diverse patient presentations.
Academic institutions such as the National and Kapodistrian University of Athens and Aristotle University of Thessaloniki, where several of the review's authors hold affiliations, contribute significantly to advancing knowledge in this area through rigorous research. Such work informs teaching materials and clinical guidelines used worldwide.
Students and faculty benefit from exposure to systematic reviews that synthesize evidence, fostering critical thinking about how psychological factors intersect with technical orthodontic skills. This prepares practitioners for holistic patient care beyond mechanics and alignment.
Challenges in Research and Clinical Application
Studying BDD in orthodontic populations presents unique difficulties. Self-reported symptoms can fluctuate, and diagnostic criteria require careful application. Heterogeneity in study designs, including varying screening tools and indices, complicates direct comparisons.
High risk of bias in some existing literature further limits generalizability. Cultural differences in perceptions of beauty and willingness to seek care add another layer of complexity, particularly in global contexts where access to mental health resources varies.
Overcoming these hurdles calls for standardized protocols in future investigations and greater emphasis on longitudinal studies tracking patient outcomes after orthodontic interventions in those with BDD symptoms.
Broader Impacts on Mental Health Awareness in Dentistry
Raising awareness about BDD among dental professionals contributes to destigmatizing mental health discussions in aesthetic medicine. Patients may feel more comfortable disclosing concerns when providers demonstrate sensitivity and knowledge.
Public health implications extend to reducing unnecessary healthcare utilization. By identifying BDD early, practitioners can guide individuals toward appropriate psychological support, potentially preventing cycles of dissatisfaction with cosmetic procedures.
Universities and professional organizations can support this through workshops, continuing education modules, and resources tailored for orthodontic teams.
Future Directions and Recommendations
Experts call for more high-quality, standardized research to clarify the BDD-orthodontic need relationship. Incorporating diverse populations and consistent methodologies will strengthen the evidence base.
Recommendations include routine BDD screening in orthodontic practices, development of clear referral pathways to mental health specialists, and ongoing training for dental educators. Personalized medicine approaches, as emphasized in the recent review, align well with evolving trends in patient-centered care.
Advancements in digital tools for assessment and telehealth options for follow-up could further enhance support for patients navigating both orthodontic and psychological aspects of their concerns.
Conclusion
The systematic review by Tsaprazlis, Lappas, Makrygiannakis, Vastardis, and Kaklamanos provides valuable insights into the nuanced and sometimes inconsistent links between body dysmorphic disorder and orthodontic treatment need. While evidence is still emerging, the work reinforces the value of comprehensive, individualized evaluations that consider both physical and mental health dimensions.
For dental professionals and academic institutions alike, this research serves as a reminder of the importance of holistic training and practice. By fostering greater understanding and collaboration across disciplines, the field can better serve patients seeking orthodontic care while supporting their overall well-being.
