The Leakage of Class II Cavities Restored with Packable Resin-Based Composites Oya Bala, BDS, PhD; Mine Betül Üçtasli, BDS, PhD; Ilknur Ünlü, BDS Recently, new resin-based composites, called “packable” or “condensable” resin composites, are being promoted as amalgam alternatives. The purpose of this study was to evaluate leakage in Class II cavities restored with the five packable resin-based composites.
	Orthodontic Treatment Planning: Do Orthodontists Treat To Cephalometric Norms? Khalid M. Al-Balkhi, BDS, MSc, PhD Cephalometric norms are important to orthodontists in their diagnosis, treatment, and evaluation of orthodontic treatment outcome.  The purpose of this study is to establish if orthodontists treat and finish their cases to the cephalometric means or norms.
	Immediate and 24-Hour Bond Strengths of Two Dental Adhesive Systems to Three Tooth Substrates Yousef Fouad Talic, BDS, MS, FICOI, DICOI, DASO Bond strengths of bonded composite resins to tooth substrates vary depending on when they were measured.  There are many different ways to measure the bond strength of direct esthetic restorations to various dental substrates.  This research uses a method published previously that compares immediate and 24-hour bond strengths of a single-bottle dental adhesive and a self-etching primer adhesive to prepared enamel, unprepared enamel, and prepared dentin substrates.
	Prediction of the Size of Un-erupted Permanent Cuspids and Bicuspids in a Saudi Sample: A Pilot Study Hayder A. Hashim, BDS, MSc;  Thakib A. Al-Shalan, BDS, MS, PhD The purpose of this study was to produce an estimated equation for the prediction of unerupted cuspids and bicuspids for the Saudi population.  Results showed the predicted tooth width of Saudis differs from the classic Moyer's chart.
	Factors Affecting Saudi Parents’ Perception of their Children’s First Dental Visit Thakib A. Al-Shalan, BDS, MS, PhD The aim of this study was to investigate the effect of different socio-demographic factors of Saudi parents on their knowledge and attitudes toward their children's first dental visit.  Interesting findings reveal parental attitudes toward behavior modification and management during the first dental visit.
	Supernumerary Fourth and Fifth Molars:  A Report of Two Cases Gulseren Kokten, DDS, PhD;  Huseyin Balcioglu, DDS;  Mete Buyukertan, DDS, PhD Panoramic radiographs of two female patients revealed the presence of two impacted bilateral upper fourth molars and unilateral (right) upper fourth and fifth molars. The characteristics of these unusual teeth are described in this case report.
	Oral Hygiene Practices, Smoking Habit, and Self-Perceived Oral Malodor Among Dental Students Khalid Almas BDS, MSc, FRACDS, MSc, FDSRCS, DDPH, FICD; Abdullah Al-Hawish, BDS; Waheed Al-Khamis, BDS The aims of this study were to determine the prevalence of oral hygiene practices and halitosis among dental students using self-reported perception of oral malodor, its possible etiology, treatment, and prevention.
