Tanaka and Johnston's Mixed Dentition Validity: An Analysis Among Yemeni Adults in Sana'a City [PDF]

Universal Journal of Pharmaceutical Research, 2022
Introduction and objective: Mixed dentition space analysis methods via Tanaka-Johnston analysis are regularly used all over the world. Conversely, the appropriate of this analysis between different ethnic groups is dubious. The study aimed to test the appropriate of the Tanaka-Johnston analysis for Yemeni adults and to arise regression equations ...

Tanaka and Johnston Space Analysis: Does It Apply to All Populations?

European Journal of General Dentistry
Abstract Objectives An accurate analysis is considered a crucial factor that enables the clinician to select the appropriate treatment plan which may include serial extractions, guiding of eruption, maintenance of space or regaining it, or just intervallic patient observation during this period.

Validity of Moyers and Tanaka-Johnston Prediction Methods for Mixed Dentition Analysis in the Pediatric Population of Central Maharashtra: A Cross-Sectional Validation Study. [PDF]

Cureus
Background Accurate prediction of the mesiodistal widths of unerupted permanent canines and premolars is essential for mixed-dentition space analysis and orthodontic planning. The Moyers' probability tables and the Tanaka-Johnston regression equations are widely used, yet their accuracy across different Indian subpopulations remains uncertain.
