Comparison between Tanaka–Johnston and Boston University Approach for Prediction of Mesiodistal Width of Canines and Premolars in Mixed Dentition Children: A Cross-sectional Study
Year: 2024
Type: article
Study design: Observational Study
Abstract: Introduction: Malocclusion, a common dental issue in children, necessitates early intervention to mitigate future orthodontic challenges. Predictive methodologies like Tanaka and Johnston analysis (TJA) and Boston University approach (BUA) aid in mixed and primary dentition analysis for optimal treatment planning. This study aimed to compare TJA and BUA in predicting the mesiodistal width of unerupted permanent canines and premolars and assess gender-based variations. Materials and methods: A cross-sectional study involving 120 children (7-11 years) was conducted at Chettinad Dental College and Research Institute, Chennai, Tamil Nadu, India. Dental models were analyzed using TJA and BUA methods. The mean predicted values of permanent canines and premolars were calculated for both approaches in the upper and lower dental arches. Pearson correlation coefficients were calculated to assess the relationship between TJA and BUA predictions, and statistical significance was determined. Results: = 0.001). Conclusion: Tanaka and Johnston analysis and BUA are valuable in mixed dentition analysis, offering insights into space availability for orthodontic treatment planning. BUA serves as a reliable substitute for TJA when fully erupted permanent incisors are absent, emphasizing the importance of tailored predictive methods in interceptive orthodontics. Model analysis remains pivotal for informed treatment decisions, ensuring optimal dental health outcomes.
