Tooth Architecture and Smile Aesthetics - Qualitative Analysis by Students versus Patients
Martins, Mariana / Manso, Maria da Conceição / Dória, Rita / Manarte-Monteiro, Patrícia
Introduction: Variations in tooth architecture parameters can influence patients and dentistry professionals (D) concerning smile aesthetic perceptions.
Objectives: Qualitative evaluation/comparison of patients and Dentistry students' perceptions regarding tooth architecture parameters and smile aesthetic appearance.
Material and Methods: An observational, cross-sectional study, approved by UFP-Ethics Committee. Two photographs (intraoral: maximum occlusion; extra-oral: smile) were taken to 35 patients (74.3% women) of CPMD-UFP. Patients completed the survey (Personalized Aesthetic Evaluation), self-assessment, after watching their own photographs. Thirty-eight FHS-UFP Dentistry students registered tooth micro/macro-aesthetic parameters (Aesthetic Checklist; Fradeani, 2004) after observing the photographs. Descriptive statistical analysis/comparison with chi-square test (α = 0.05).
Results: Patients: satisfaction with tooth shade (60%), with smile (80%), beautiful smile (83%); Interest in changing smile aesthetics (42.9%). Students: square/ovoid (40.8%) tooth shape, normal tooth shade (53%), average tooth length (61.7%), higher CI dominance (66.2%), tooth midline without deviation (55%), normal tooth axes (52.2%), tooth proportionality (51%), tooth asymmetry (54%); 36.4% of smiles considered aesthetic. Patients versus student's compliance ratio (p<0.001) in all evaluated criteria, except regarding the tooth midline parameter. More studies should be applied to different populations and rehabilitation fields.
Conclusions: Most patients showed satisfaction with their tooth architecture/smile aesthetics; patients' perceptions versus students were in agreement on almost all tooth macro/micro-aesthetic parameters evaluated.
Clinical Implications: Tooth architecture/Smile aspect analysis is a communication tool for professional/scientific criteria and patient expectations in planning cosmetic/aesthetic changes.
