“Correlation Between Tooth Mineralization Using Cbct And Mp3 As A Diagnostic Tool For Assessment Of Skeletal Maturity - A Radiographic Study”

Background And ObjectivesTreatment timing has a significant role in the outcome of all dentofacial orthopedic treatments for dentoskeletal disharmonies in growing patients. Dental maturation has been proposed to be a clinically useful diagnostic aid for the identification of individual skeletal maturation stages. Aims: 1) To correlate dental calcification stages with MP3 stages in skeletal age estimation using CBCT of the left mandibular posterior teeth. 2) To determine whether dental calcification can be used as a first level diagnostic tool for assessment of skeletal maturity with MP3 stages. Materials And Method – Study design included a total sample size of 30 including boys and girls, between the age group of 8 to 18 years visiting Vydehi Institute of Dental Sciences for orthodontic treatment. After analyzing the skeletal maturity through MP3 stages of each individual, it was compared with CBCT images Panoramic view and the respective stages of MP3 were correlated with CBCT Panoramic view for each tooth under investigation. The data was subjected to statistical analysis to determine the degree of correlation between the two maturation indices i.e. dental maturity and skeletal maturity with the help of Spearman Rank correlation coefficient and Sensitivity –Specificity analysis was done to identify the diagnostic ability of tooth mineralization stages to be used as a first level diagnostic tool for identification of skeletal maturity over other methods. Results: 1) Significant correlation was seen between dental mineralization stages and MP3 method of skeletal maturation with 2 nd premolar stages being most reliable for skeletal maturity assessment. 2) The acceptability of the method to be used as first level Diagnostic tool is still not clear, though it can be used as a supplemental method along with principal method for skeletal maturity assessment. ConclusionBased on our study it is clear that second premolar has the highest significance level to rely on mineralization stage of the teeth to assess the skeletal maturity, and DMS method is more accurate in diagnosis of prepubertal individual than post pubertal individual with 2 nd molar having the highest sensitivity.
