Prediction of New Regression Equation Using Digital Analysis for Determination of Mesiodistal Width in Permanent Teeth Among a Group of Egyptian Children : a Cross Section Study

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)

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Accepts Healthy Volunteers

Yes

Sampling Method

Probability Sample

Study Population

The study sample will include healthy cooperative children. The children age will range from 12 years to 15 years. They will be selected from the outpatient clinic of Pediatric Dentistry Department of Faculty of Oral and Dental Medicine, Cairo University, according to the following inclusion and exclusion criteria

Description

Inclusion Criteria:

- 1. Subjects age between 12-15 years. 2. Positive subjects acceptance for participation in the study. 3. Full set of the permanent dentition from left 1st permanent molar to right 1st permanent molar.

4. Subjects selected with no previous orthodontic treatment to eliminate possibility of any interproximal reduction. 5. Intact marginal ridge

Exclusion Criteria:

- 1. Subjects with history of systemic diseases. 2. Subjects who have any sensitivity or adverse reactions to any of used materials.

3. Subjects with morphologic anomalous.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Measuring mesiodistal width in permanent mandibular anterior teeth, maxillary, mandibular canines and premolars among a group of Egyptian children
Time Frame: baseline

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2025

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
