Measuring buccolingual inclination of mandibular canines and first molars using CBCT
Orthod Craniofac Res 2011; 14 :168–174 Structured Abstract Authors – Shewinvanakitkul W, Hans MG, Narendran S, Palomo JM Objectives – To develop a reliable method to measure buccolingual inclination of mandibular canines and first molars, and to evaluate a possible correlation between buccolingual inclination with their respective interdental width. Methods – The sample consisted of 37 boys and 41 girls untreated orthodontic patients averaging 13.2 ± 0.96 years. A line tangent to the inferior border of the mandible and the long axis of the tooth measured buccolingual inclination. Intercanine and intermolar widths were measured on casts. Results – Reliability (ICC) values were >0.94. The mean mandibular canine inclination was 98.0 ± 4.1°, with mean width 26.0 ± 2.2 mm. The mean mandibular molar inclination was 74.6 ± 4.7° with mean width 40.9 ± 2.7 mm. First molar inclination of Class II molar subjects (73.7 ± 4.2°) was significantly less ( p ≤ 0.05) than of Class I subjects (75.6 ± 4.9°). There were low correlations between interdental width and buccolingual inclination. Conclusions – A practical and reliable method to measure buccolingual inclination of mandibular canines and first molars is here described using Cone Beam Computed Tomography and a commercially available DICOM software.
