Aims: Despite the growing concern that the prevalence of dental erosion has increased amongst children, the data on its prevalence is still scarce in Libya. Therefore, this study aimed to measure the prevalence of dental erosion and examine gender differences in relation to its prevalence in a group of schoolchildren in Benghazi, Libya.

Background: The mental foramen is one of important anatomical features frequently encountered in maxillofacial surgical procedures in premolars area. Its position has been shown to vary according to race. In this study researchers aim to study the position, shape, and appearance of the mental foramen, as seen on panoramic radiographs of Palestinians, and to compare our findings with international values.

Implant stability plays a critical role for successful osseointegration, which has been viewed as a direct structural and functional connection existing between bone and the surface of a load-carrying implant. Achievement and maintenance of implant stability are prerequisites for successful clinical Outcome. Therefore, measuring the implant stability is an important method for evaluating the success of an implant. The aim of this clinical study was to measure the implant stability quotient using a method called resonance frequency analysis of dental implants during the healing period.

Objective: The objective of this retrospective study was to evaluate the success rate of AL Technology implants used for single tooth replacement after a minimum of three years of loading at Center for Dentistry, Research & Aesthetics, Jatt, Almothalat, Israel. Method: Dental records for 43patients who underwent single tooth replacement using ALTechnology implant system at Center for Dentistry, Research & Aesthetics, Jatt, Almothalath, Israel during a three years period (2010-2012) were retrospectively analyzed. Only implants that were functioning for at least three years were included.

Background: The management of the clinically and radiological negative neck in patients with early squamous cell carcinoma of head and neck (HNSCC) is still controversial. As approximately 20 to 30% of these patients harbor occult neck disease, most of them is submitted to elective neck dissection with no benefit in great majority of those cases. Sentinel lymph node biopsy (SLB) is a potential method for staging of lymphatic metastasis in HNSCC and the status of the sentinel node predicts the presence of metastasis in the remainder of the nodes within the nodal basin.
