Abstract

Introduction: Incisive canal is an important anatomical landmark in the pre-maxillary segment of the maxilla. This landmark is of quite a significance in Orthodontics especially WHILE doing anterior maxillary intrusion and retraction as well as placing TADs in the pre-maxillary segment. The aim of this study was to determine the anatomical dimensions and morphological forms of incisive canal in Orthodontic patients based on the pre-treatment CBCT findings in south Indian population.

Materials & Methods: This study included 100 CBCT’s, 50 each of male and female which were examined for the measurement of nasopalatine canal labiopalatally, Length of the canal, width of the bone anterior to canal, Mesiodistal width of incisive foramen. The morphology of the incisive canal was also examined according to the Mardinger’s classification. Patients were classified into two age groups – Group I: age 15-25, Group II: age 26-36. To eliminate bias, three observers did all the measurements, and the average value was taken.

Results: The data was tabulated in excel sheet and Statistical software, namely SPSS 22.0, and R environment ver.3.2.2 was used for the analysis and to generate graphs, tables. Mean, standard Deviation and standard Error was derived. Student t-test was used to determine the correlation. In all the parameters, males had greater dimensions as compared to females. Age wise, the dimensions of all parameters were same with no statistical significance. Cylindrical shape of incisive canal was most commonly prevalent followed by the funnel shape in both the genders.

Conclusion: the study concluded that the dimensions of the incisive canal were greater in males as compared to females. Age wise there was no significant difference in the dimensions. Cylindrical shape of incisive canal was more prevalent. Pre-treatment CBCT of the pre-maxillary region should be included in the diagnostic armamentarium of orthodontics which can be helpful in planning the orthodontic tooth movement & retraction in the incisal region.
