Mandibular dimensions are one of the key parameters for planning the treatment by an Orthodontist. Lateral cephalograms are usually used to evaluate the skeletal relationship. However, due to the superimposition of both the sides, lateral cephalogram may not be reliable in measuring the right and left sides of the cranial landmarks. Panoramic radiography delivers a wide-ranging view of maxillofacial structures with comparatively lesser radiation exposure than other tools and superimposition of structures is less compared to lateral cephalogram image. OPG and lateral cephalograms of all the patients of age group 16-35 years attending Department of Orthodontics in Nepal Medical College from September 2022 to February 2023, having Angle’s Class I Molar relationship with minimum crowding was taken. Linear measurements (ramus height, total mandibular length and mandibular body length) were measured on OPG and Lateral cephalogram. The data was processed in SPSS version 17 for further analysis. There was no statistically significant difference in mean linear measurements between right and left sides on OPG (p-value 0.77, 0.49 and 0.59 respectively). But there was a statistically significant difference in mean linear measurements between both sides on OPG and lateral cephalograms (p-value <0.001). OPG can be used reliably to measure the mandibular length and ramus height of right and left side but comparison of mandibular length and ramus height between lateral cephalogram and OPG may not be reliable.

“…It depicts the form and shape of the mandible, has a pivotal role in forecasting future mandibular growth, and has certain effects on the profile and position of the mandibular anterior teeth. [ 3 ] On the lateral cephalogram, the gonial angle is measured by taking the tangent to the posterior border of the ramus and the tangent to the lower border of the mandible. Its accuracy of measurements on lateral cephalograms may be affected by the superimposition of the patient's right and left sides.…”

OBJECTIVES: This study aimed to investigate the correlation of gonial angle and three linear measurements on OPG and lateral cephalograms and their effects on the different facial patterns using the OneCeph android app. METHOD: About 90 pre-treatment digital lateral cephalograms and OPGs of 90 patients were selected and divided into 3 categories, based on their growth patterns. The OPGs and lateral cephalograms were uploaded on the OneCeph android app. After calibrating using One linear measurement i.e. length of extracted premolar for OPG and ruler in radiograph for lateral cephalogram, Gonial angle (Ar- Go-Me), ANS-Me (LAFH), U1-NF, L1-MP were measured. The data were collected, tabulated, and subjected to statistical analysis using the SPSS software (version 20.0). The level of significance was kept at 5%. RESULTS: Values for parameters were highest in the vertical growth pattern followed by average and horizontal in both cephalogram and OPG. Upon comparison of lateral cephalogram and OPG, no significant difference was observed in gonial angle and a significant difference in LAFH and L1-MP in all three growth patterns with OPG scores greater than cephalometric tracing. The interclass coefficient test indicated almost perfect agreement for the gonial angle between the two methods. A substantial agreement was seen for U1-NF on lateral cephalogram and OPG in the vertical group. Also, a fair agreement in the vertical and horizontal group was observed in Lower anterior mandibular height. CONCLUSION: Vertical parameters such as gonial angle and maxillary anterior dental height can be accurately determined on an OPG by the OneCeph application.

“…All the values that we got from OPG were compared with that of lateral cephalometric 11,12 values (Table 2) for proper reliability of the study. Following measurements were made-length of the ramus, length of the corpus, effective height of the corpus, cephalometric gonial angle, cephalometric mandibular plane angle, cephalometric condylar inclination, and occlusal plane angle.…”

Aim: Vertical malocclusion is an important and commonly seen anomaly of the craniofacial complex. The aim of the present study was to evaluate and compare the efficiency of the orthopantomogram (OPG) over the lateral cephalogram. Materials and methods: A total of 60 radiographs were collected from patients. Independent reference planes were set up in the maxilla and the mandible. The inclusion criteria of the study involved subjects in the age group of 20-25 years, class I skeletal and dental relationship with an overjet, and overbite in the range of 2-4 mm with an orthognathic profile. Exclusion criteria involved crowding, asymmetry, or spacing along with no history of prior orthodontic or surgical treatment. Mean values were evaluated using the z test. The statistical analysis was performed by using the Statistical Package for the Social Sciences. Results: Significant values were obtained for effective length of ramus, effective length of corpus, effective height of corpus, interocclusal distance, panoramic alternative of gonial angle (PGOA), panoramic alternative condylar inclination (PCOI), panoramic alternative of mandibular plane angle (PMPA), and maxillary occlusal angle. Conclusion:On completion of our study, we can conclude that the OPG can be used in the assessment of vertical malocclusion quantitatively. Clinical significance: Less radiation exposure and easy availability of OPGs will be useful clinically.
