Malocclusion severity and self-perceived facial esthetics moved in the same direction
A cross-sectional study of 263 participants found a meaningful gap between how teeth and bites were measured clinically and how they were experienced by the people living with them. Using the Orofacial Esthetic Scale and the Dental Aesthetic Index, investigators showed that increasing objective malocclusion severity was associated with lower subjective esthetic satisfaction. The relationship was not a trivial one: the continuous scores moved in opposite directions with a moderate inverse correlation, Spearman’s ρ = −0.407, p < 0.001.
The finding matters because orthodontic evaluation often relies on normative indices that describe alignment, spacing, and occlusal relationships from a clinician’s point of view. Patient perception is a different clinical endpoint. A person can present with a bite that scores poorly on an index and still feel comfortable with appearance, while another may experience substantial esthetic distress from a smaller but highly visible irregularity. This study places those two viewpoints side by side and shows they do not behave identically.
Female participants reported lower esthetic satisfaction in the unadjusted analysis
The cohort included 163 females and 100 males. In the unadjusted comparison, females had lower OES scores than males, with median scores of 44.0 versus 47.0 and a p value of 0.034. In practical terms, that suggests women in this sample judged their orofacial appearance more critically when assessed with a self-reported esthetic scale.
One sentence captures the central divergence: objective malocclusion severity and subjective satisfaction were linked, but they were not interchangeable measures.
Education level showed a different pattern. DAI category distribution was significantly associated with education level, p = 0.010, yet OES scores themselves did not differ significantly across education groups, p = 0.436. Gender and age group also did not show significant associations with DAI category distribution, with p values of 0.235 and 0.080, respectively. Those results suggest that the structural severity of malocclusion and the personal experience of appearance are shaped by overlapping but not identical factors.
Specific bite traits drove lower OES scores after adjustment
The multivariable model sharpened the picture. Once demographic variables were accounted for, three occlusal features remained independently associated with lower subjective esthetic ratings: largest anterior maxillary irregularity, maxillary overjet, and mandibular overjet. Their regression coefficients were β = −1.690, p < 0.001; β = −1.337, p = 0.005; and β = −3.182, p = 0.002, respectively.
Those are not abstract numbers. They point to visible traits that are easy for patients to see in mirrors, photos, and social settings. Anterior maxillary irregularity affects smile continuity and tooth alignment in the front of the mouth, where esthetic judgment is immediate. Overjet alters the sagittal relationship between upper and lower incisors, changing lip support, tooth prominence, and the visual profile of the smile. Mandibular overjet, although less common, can create a more noticeable anterior discrepancy and may carry a stronger impact on self-image because it is difficult to camouflage.
The adjusted model also showed that gender, age, and education level were not independently associated with subjective esthetic satisfaction once occlusal features were included. In other words, the visible dental configuration carried more explanatory weight than the demographic profile once the model was fully specified.
Why a patient-reported esthetic scale belongs next to normative orthodontic indices
Orthodontic practice has long depended on objective indices to classify malocclusion severity, compare cohorts, and guide treatment priorities. Those tools remain useful, but they do not fully capture the lived experience of dental appearance. The OES offers a patient-centered layer of information that can reveal when a person feels distressed by features that may appear modest on a clinical chart, or when a more severe malocclusion is tolerated without major subjective concern.
This distinction has bedside consequences in consultation rooms. A treatment plan based only on severity scoring can miss the emotional and social burden attached to anterior irregularity or altered overjet. A patient who reports low esthetic satisfaction may be signaling a greater desire for orthodontic correction, stronger motivation for treatment, and a different threshold for accepting long treatment timelines or appliance-related inconvenience. On the other side, an individual with a higher DAI category but stable self-perception may prioritize function, cost, or risk differently than the clinician expects.
The biological logic is straightforward. The anterior segment of the dentition sits inside the visual field that drives facial appraisal, speech-related visibility, and smile aesthetics. Small deviations in that zone are magnified by social attention, which helps explain why anterior irregularity and overjet remained significant after adjustment while broader demographic variables did not.
Study design and limits frame how far the findings can be taken
This was a cross-sectional study, so it captures association rather than change over time. It cannot determine whether correcting malocclusion will produce a proportional rise in OES scores, nor can it measure how quickly perceptions shift after treatment starts or ends. The sample came from a single setting, and the article does not provide evidence that the same strength of association would appear in different age distributions, cultural contexts, or treatment-seeking populations.
Even with those boundaries, the clinical message is concrete: objective malocclusion severity and subjective esthetic perception are related, but not perfectly aligned. The strongest signal in this cohort came from anterior irregularity and overjet, the features most likely to dominate what patients see when they look at their own teeth. Orthodontic evaluation becomes more complete when both the dental index and the patient’s own esthetic judgment are placed in the same conversation.
The next step is not a broader slogan about patient-centered care. It is a more specific question for future orthodontic cohorts: how much esthetic gain do patients actually experience after targeted correction of the anterior segment, and which occlusal changes matter most to them at the chairside.
