A validated questionnaire based on the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) was used, covering eight domains: Self-confidence, social impact, esthetic concerns, psychological impact, speech impairment, functional limitations, matrimonial concerns, and career concerns. Each of the 16 items was scored on a 5-point Likert scale. Data were statistically analyzed using SPSS (Version 30.0), with significance set at <i>p</i> < 0.05. Reliability was assessed using Cronbach's α.</p><p><strong>Results: </strong>The study sample comprised <i>n</i> = 333 Indian individuals between 12 and 40 years of age. The overall questionnaire reliability was acceptable (α = 0.751). Self-confidence concerns showed no gender difference (males: 72, 31.6%; females: 151, 34.5%; <i>p</i> = 0.162). Esthetic concern was higher in males (91, 39.9% with no concern) than in females (243, 55.5%; <i>p</i> = 0.001). Social impact was reported more by males (98, 43.0%) than by females (110, 25.1%; <i>p</i> < 0.001). Matrimonial concerns were greater in males (28, 12.3% severe) compared to females, where most (270, 61.6%) had no concern (<i>p</i> < 0.001). Functional difficulty was more frequent in males (23, 10.1% severe) vs females (18, 4.1%), with 300 females (68.5%) unaffected (<i>p</i> < 0.001). Career, speech, and psychological concerns were also significantly higher among males, while females more often reported no concern across domains.</p><p><strong>Conclusion: </strong>The study demonstrates that individuals with definite malocclusion perceive a substantial psychosocial and esthetic burden even before undergoing orthodontic treatment. Participants commonly reported diminished self-image, lower social confidence, and emotional distress, indicating that malocclusion affects more than just dental function. These perceptions were key motivators for seeking orthodontic intervention, reflecting the strong influence of appearance- and confidence-related concerns, alongside functional needs, on their decision to pursue treatment.</p><p><strong>Clinical significance: </strong>Malocclusion affects not only dental alignment but also mental well-being, self-esteem, and social interactions. This study highlights the importance of assessing psychosocial impacts in untreated individuals to establish meaningful pretreatment benchmarks. Orthodontic care emerges as a transformative intervention that enhances self-image, emotional stability, and overall quality of life. Incorporating patient-reported outcomes into routine assessment allows for more holistic and personalized treatment planning.

The buccal surface of the teeth was prepped for class V cavities, with the cervical borders placed 0.75 mm apical to the CEJ and the occlusal edge in the enamel. Each cavity measured 1.5 mm in depth, 4 mm in width, and 4 mm in length. All samples were randomly allocated to one of the following groups, with 25 samples in each group-group I: application of chitosan nanoparticles, group II: application of hesperidin solution, group III: application of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP). For every sample, adhesive was applied. A universal testing machine was used to assess the shear bond strength. Data were recorded and statistically analyzed.</p><p><strong>Results: </strong>The casein phosphopeptide-amorphous calcium phosphate group at 146.16 ± 1.01 showed the maximum shear bond strength, followed by the chitosan nanoparticles group at 142.74 ± 0.98 and the hesperidin solution at 128.26 ± 0.74. A statistically significant difference was found among the three groups.</p><p><strong>Conclusion: </strong>The present study concluded that the CPP-ACP group exhibited the maximum shear bond strength compared to the chitosan nanoparticles group and the hesperidin solution group.</p><p><strong>Clinical significance: </strong>Dentin biomodification has been highlighted as a way to strengthen the binding between composite resin and the tooth surface, hence extending its lifespan. By adding dentin biomodifiers to dental adhesives, the stability of the resin-dentin interface may be improved, and MMP inhibitory capacity may be added.
