Objective: To determine the correlation of different depths of the curve of Spee with overjet and overbite.
Materials and Methods: This cross-sectional study was conducted on 85 participants by non-probability consecutive sampling technique from June 2018 to January 2019 at the Department of Orthodontics, Khyber College of Dentistry, Peshawar. Patients with healthy, complete permanent dentition and skeletal Class I was included. Patients with any previous orthodontic treatment, severe craniofacial disorders such as cleft palate, skeletal Class II, and Class III and any congenitally missing maxillary or permanent mandibular teeth, except for the third molars were excluded. The depth of curve of Spee, overjet, and overbite was measured on casts. Descriptive statistics were calculated in SPSS 20.0. Pearson’s correlation test was used to determine correlation coefficients of the curve of Spee with overjet and overbite. P≤0.05 was considered significant.
Results: Out of total most were females n=49(57.65%), and the males were n= 36(42.35%). The mean overjet was 2.559±1.7379 mm; overbite was 2.553±2.6038 mm, age was 18.44±4.602 years and curve of spee was 2.6029±.93882mm. Correlation between the curve of Spee and overjet in the whole sample was positive but weak (r= 0.334, P=0.002). Similarly, the correlation between the curve of Spee and overbite in the whole sample was positive but weak (r= 0.352, P=0.001). In males, the Correlation between the curve of Spee and overjet was positive and moderate (r=0.447, P=0.006) while in females was positive and weak (r=0.307, (P=0.032). In males, the correlation between the curve of Spee and overbite was positive and strong (r=0.615, P<0.001) while in females was positive and weak (r=0.239, P=0.098).
Conclusion: The correlation between the curve of Spee, overbite was weak. The correlation between the curve of Spee and overjet was more in males than females. The correlation between the curve of Spee and overbite was more in males than females, and female the correlation was non-significant. With increasing age, the correlation reduces, and in later ages it becomes negative
