Relationship Between Basal Mesiodistal Crown Widths of Deciduous SecondMolars and the Permanent First Molars

IntroductionnbspDental crowding is a common malocclusion in children that is often seen during the transitional dentition phase. The choice of an appropriate treatment strategy may be influenced by various factors contributing to crowding. Thus the studys goal was to evaluate the potential for early prediction of crowding by analysing the mixed dentition stage using the mesiodistal dimensions of primary second molar first permanent molar and arch length measurements.nbspObjectivenbspThe purpose of this study was to ascertain in the Karnataka local population the relationship between the basal mesiodistal widths of first permanent molars and second primary molars.nbspMethodologynbspFor this observational study casts of 150 children in the age range of 8 to 11 years were chosen as the sample. The selected mandibular and maxillary casts were trimmed to the basal bone and examined. With the caliper positioned parallel to the occlusal surface the maximum mesiodistal width was measured by identifying the greatest distance between the mesial and distal contact points. All the measurements were recorded by a single inspector and the resulting data were tallied and utilized for statistical examination.nbspResultsnbspA new technique that predicts malocclusion based on the permanent first molar and the primary second molar widths was developed based on the highly significant correlations observed between the teeth.nbspConclusionnbspUtilizing the widths of the first permanent molars and the adjacent deciduous second molars a novel approach for predicting dental crowding was developed.
