Abstract
For years, it has been taught in dental schools that the mesiodistal width of lower primary molars in flush terminal plane type of occlusion are larger than of those in mesial step molar relationship. It has been proven that approximately in two thirds of cases, permanent occlusion can be predicted from molar relationship in primary dentition. This is an emphasis to the fact that primary molars potentially play an important role in establishment of molar relationship in the permanent dentition.
Some investigators have shown that there are other factors that influence in determination of molar relationship. Growth of dental arches and path of eruption of tooth are the examples of those parameters that should be taken into consideration.
For the purpose of this study, 25 patients were selected who only exhibited primary dentition, contributing 50 cases to this investigation. Each patient was evaluated as two cases of right and left side of the mouth if presented mesial step or flush terminal plane relationship.
This study was performed to compare the mesiodistal size of upper and lower primary second molars in flush terminal plane cases with those in mesial step type of molar relationship. This comparison was made by measuring the anteroposterior size of the primary second molars of the above two samples of dental occlusion. The measures were obtained by a boley guage on the dental casts of maxillary and mandibular arches.
Findings of this investigation indicate that a larger mesiodistal width of primary second molar exists in flush terminal plane relationship than in mesial step.
