| Summary: | Introduction: Diagnosis and treatment planning in orthodontics
determines the treatment outcome and long term stability.
Cephalometric radiography is an essential diagnostic aid in
orthodontics and hence numerous studies have been carried
out in the past.
Aim: To determine the Combination Factor (CF) through
evaluation of the mean Overbite Depth Indicator (ODI) and
Anteroposterior Dysplasia Indicator (APDI) values in western
region of Saudi Arabian young male patients which would act
as an aid in orthodontic treatment planning.
Materials and Methods: A retrospective cephalometric study
was conducted on 80 Saudi Arabian young male patients ranging
in age from 7 to 14 years. Data was collected from records
derived from the University Dental Hospital. Patients (n=80)
were divided into four age groups: ages 7 (n=20), 8-9 (n=20),
10-11 (n=20), and 12-14 (n=20) years. Lateral cephalometric
images were hand-traced and measured by one standardised
and calibrated investigator. Statistical analysis was done with
significance level set at 0.05, assuming that the length of the
95% confidence interval was two. One-way analysis of variance,
followed by the Tukey test used to compare the mean ODI
and APDI values of different groups. The statistical data were
analysed through SPSS version 24 for Windows (IBM SPSS,
Chicago, IL, USA).
Results: The mean ODI value was 69.2688° and standard
deviation 4.66670°, respectively. The overall APDI mean value
was 81.7063° and standard deviation 4.18987°, respectively.
There were no significant differences in the mean ODI and APDI
values among different age groups (p>0.05).
Conclusion: This retrospective cephalometric study determined
the CF for western region of Saudi Arabian young male
population to be 150.96°. This factor can be used as a diagnostic
aid for planning orthodontic treatment. When the CF, is under
the norm (150.96°), the skeletal pattern tends to improve with
dental extractions. A CF higher than the norm (150.96°) will
maintain a better relation with a non-extraction treatment. |
