Study Notes
- The study focuses on the mesiodistal diameters of upper and lower premolars in a population with normal occlusion in Matanzas, Cuba.
Introduction
- Individual variations in arch growth during childhood and adolescence necessitate monitoring and precise measurements for accurate prediction of unerupted teeth.
Objective
- To determine the mesiodistal diameter of upper and lower premolars.
Methods
- A descriptive cross-sectional study was conducted on adolescents with normal occlusion.
- The sample comprised 362 students (174 females, 188 males) aged 12-14 years from basic secondary schools in Matanzas, selected via simple random sampling.
- Measurements were taken directly in the mouth from the mesial to distal contact point at the level of the tooth's greatest diameter, using calipers.
- The study variables were age, sex, and mesiodistal diameter of upper and lower premolars.
Results
- The average mesiodistal measurements for upper back teeth were:
- First right premolars: 6.9 mm
- First left premolars: 7.0 mm
- Second right premolars: 6.8 mm
- Second left premolars: 6.9 mm.
- The average mesiodistal measurements for lower back teeth were:
- First right premolars: 7.1 mm
- First left premolars: 7.0 mm
- Second right and left premolars: 7.0 mm
Conclusions
- Lower premolars were generally larger than their upper counterparts.
- Significant sex-based differences were found in the sizes of lower right first premolars and lower left second premolars.
- Male premolars tended to have larger mesiodistal dimensions compared to female premolars.
