Dimax3 digital system pan/ceph,PLANMECA, Helsinki, Finland was used for panoramic Radiological techniques. Intraoral periapical exposurewas done using the same digital radiological system. The X-ray unit operated at range of 70-80 kV and 10-12 mA according to the patient age for panoramic technique while 70KV,8Ma for periapical techniquewhich was done according to the user manual of the machine.Posterior periapical image were taken by paralleling technique. Five observers assessed the marginal bone level inboth techniques independently.Results: Assessments of the marginal bone level by five observers for both techniques were analyzed by pairedsamples t-test, Anova test and reliability test. The statistical analysis of marginal bone level show no significantdifferences in periapical radiological techniques, while in panoramic radiological techniques shows high significantdifferences between the observers.Reliability test (used for measuring the degree of agreement between the first observer and other observers), showhigh degree of agreement in periapical technique than panoramic technique in assessment of alveolar bone level.The overall agreement in periapical technique for observer one and two, three, four, five was 81.3%, 93%, 90.1%,75.6% respectively. While in panoramic radiography was 51.7%, 19.2%, 35.8%, 28.2% respectively.Conclusion: It was concluded that digital periapical view could be considered the radiological techniqueexamination of choice for assessment of marginal bone level, comparing with digital panoramic technique.
