Abstract

Background: This study aimed to evaluate the reliability and repeatabilityof digital, panoramic and intraoralperiapical Radiological techniques in the assessment of marginal bone level.Materials and method: Digital, panoramic and periapical Radiological techniques were performed for forty eightrandomly selected patients between twenty five to the thirty five years of old. 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.

Abstract

Background: Sonographic examination is an important tool in assessment of normal and abnormal cervical lymphnodes. The aim of the study is to assess the distribution and the characteristic features of normal cervical lymphnodes in a sample of Syrian population.Materials and Methods: Fifty healthy Syrian subjects (25 men and 25 women) with an age of 20 -60years old, whohad their cervical lymph nodes examined by ultrasound. Three hundred and two lymph nodes were detected.Lymph nodes were evaluated for their number, size, site, echogenic hilus, shape, as well as for the border sharpness.The subjects were categorized by age into four groups, (20 -30, 31 - 40 , 41 - 50 , 51- 60 years ). Statistical analysis ofdata was done using SPSS software (version 11.5), and analytical one way analysis of variance (ANOVA), Duncan’sMultiple Range Test.Results: The results showed that there was no significant difference in mean number of nodes between different agegroups. All lymph nodes were hypoechoic; majority of them possessed an echogenic hilus, with transverse diameterof 8 mm or less. All lymph nodes were oval except for submandibular and parotid nodes which appeared round.Conclusions: This study provides a sonographic appearance of normal cervical lymph nodes in relation to their site,size, shape, numbers, border sharpness, and echogenic hilum, in a sample of Syrian population
