Brief Summary

Aim of the study:

Prediction of new regression equation using digital analysis for determination of mesiodistal width of permanent teeth among a group of Egyptian children.

Research question What is the combined mesiodistal dimensions of canines and premolars in a group of 12-15 years old Egyptian children and from it Can the new regression equation predict the size of unerupted canines and premolars?

Detailed Description

Tooth size varies significantly between racial groups so mesiodistal dimension in permanent teeth of Egyptian children differ from any international equation, and to the present data, few studies on the mesiodistal dimension of teeth for Egyptian population (Salem et al., 2023).

Tooth size and shape varies from one person to another, from males and females and from one ethnic group to the other depending on genetic factors (Aljuaid et al., 2021).As mandibular incisors are the first teeth to erupt in the permanent teeth and if their dimensions could perhaps be used for predicting the width of unerupted teeth, then it may be advantageous for analysis of mixed dentition at an early age (Moyers, 1976).Environment and genetics both affect tooth size and it's strongly linked to sex and ethnicity. Males' teeth are larger in size than those of the females and Africans have larger teeth than Europeans (Aldeeb, 2021).

Rationale Tooth size differs among and within populations. Tooth size specifically the mesiodistal dimension has an important role in normal occlusion and in arch space analysis as it affects treatment planning and the final results in orthodontic treatment. (Abozeid et al., 2019). Malocclusion is a common esthetic and functional problem in the world. It's a developmental condition caused by alteration in normal development (Ghorbani et al., 2018). The majority of malocclusion, which starts during the mixed dentition period, can be treated and eliminated in its severity if it was managed early (Abozeid et al., 2019).Predicting the size of canines and premolars that have not yet erupted is essential for accurate diagnosis and planning of the optimal course of action throughout the mixed dentition. The exact forecast reveals the difference between the amount of space needed and that which is now available, providing the first component of a successful therapy (Salem et al., 2023)
