Mesiodistal tooth width in a Saudi population sample comparing right and left sides. Part 2

Area of Science:

• Dentistry
• Orthodontics
• Dental Morphology

Background:

• Mesiodistal tooth width is a critical parameter in orthodontic diagnosis and treatment planning.
• Assessing symmetry in tooth dimensions is essential for achieving optimal occlusal outcomes.
• Previous research has explored tooth width variations, but specific data on Saudi populations is limited.

Purpose of the Study:

• To determine if significant differences exist in mesiodistal tooth width between the right and left sides of the dental arch in a Saudi sample.
• To provide data that can inform orthodontic treatment planning and minimize potential biases due to asymmetry.

Main Methods:

• Utilized pretreatment orthodontic study casts from 720 Saudi individuals.
• Measured the mesiodistal width of teeth on both the right and left sides of the dental arch.
• Employed statistical analysis to compare measurements between contralateral sides.

Main Results:

• No statistically significant differences were observed in mesiodistal tooth width between the right and left sides.
• The findings align with existing literature on dental arch symmetry.
• This indicates a high degree of bilateral symmetry in tooth dimensions within the studied sample.

Conclusions:

• Mesiodistal tooth width measurements from one side of the dental arch can be reliably used as representative for the contralateral side in Saudi orthodontic patients.
• This simplifies data collection and analysis in orthodontic practice.
• The study supports the assumption of symmetry in tooth width for treatment planning in this population.
