Introdouction:
The aim of the present study was to investigate
image magnification in digital panoramic radiography
and assess the effect of anatomical sites
on the magnification in both males and females.
Materials and methods:
In this retrospective study, digital panoramic
radiographs of 48 patients with 202 implants
were investigated. Implant diameter and length
were measured on panoramic radiographs and
the horizontal and vertical magnification rates of
each placed area were calculated based on the
length and width of the placed implant. A twoway
ANOVA test was used to evaluate the magnification
rate in regard to implant location and
gender.
Results:
The range of the magnification factor of the
width was 111.09–126.02, which was lowest in
the maxillary molar region and greatest in the
mandibular anterior region. While the lowest
magnification value of the length (111.58) was
observed in the mandibular molar region, the
highest value (116.09) appeared in the maxillary
premolar area. Hence, there were no significant
differences in image magnification with regard
to anatomical site and gender.
Conclusion:
Digital panoramic radiography can be reliably
used for pre-implant evaluation in various anatomical
sites of the jaws in both genders.
