Objective: To identify the cephalometric features of three skeletal jaw relations (Class I, II, and III) in the United Arab Emirates (UAE) local population approaching for orthodontic consultations in males and females. Materials and Methods: A retrospective imaging study of pre-treatment orthodontic cephalometric records of male and female patients from a similar ethnic background was retrieved from clinics in the Northern Emirates. A total of fifty-four lateral cephalometric x-ray samples were selected of orthodontic patients aged between 18 to 40 years and were observed for 8 angular and 6 linear. The 18 cephalometric images were subdivided as 9 males and 9 females into each of Class I, II, and III categories. Results: The majority of angular and linear measurements for the three skeletal types had significant differences amongst the males and females. The anterior and posterior cranial base length and lower anterior facial height showed lower values in class III females and the length of the maxilla (ANS-PNS) showed higher value in Class III males. The length of the mandible (Go-Pog), and lower anterior facial height for male was significantly longer than females in Class III. The Interincisal angle (U1-L1) demonstrated a significant difference among the three Classes with the highest value in Class III followed by Class I and then Class II Conclusion: This study provides us a reference or database for Emirate's population characteristics, which aids in achieving more precise, effective, and successful orthodontic treatments.

The purpose of this study was to examine the inhibitory effect of fresh cranberry, strawberry and blueberry juices on the viability of oral Streptococcus mutans, Streptococcus pyogenes and Streptococcus viridans. Modified agar-well diffusion method was used to determine the antimicrobial activity of the fruit juices. A 100µl volume of the test solution was added into wells of the agar plates and zones of inhibition were measured following incubation. The fresh cranberry juice, the three powders, and the mixed juices and juice powders had an antibacterial effect on S.mutans, S.pyogenes and S.viridans. The greatest zone of inhibition was observed with the fresh cranberry juice and juice powder of the same. The fresh strawberry juice showed an antibacterial effect on S.viridans. However, the fresh blueberry juice failed to provide an antibacterial effect on any of the tested pathogens. This study concludes that the cranberry juices have a good inhibitory effect on the colonization of oral S.mutans, S.pyogenes and S.viridans. [ABSTRACT FROM AUTHOR]
