Aim: Knowledge of the position of the mental foramen is important to prepare strategy when administering regional anesthesia, performing dental surgical procedures, endodontic treatments. Also, it is critical to analyze diameter of mental foramen in sagittal, coronal, and axial images.  The aim of this retrospective study was to determine the diameter of the MF in different planes from CBCT images. Methodology: This study was designed at Department of Endodontics, Dicle University, Diyarbakır, Turkey. One hundred twenty three (67 female, 56 male) CBCT scans that met the study criteria were obtained. All images were obtained from i-CAT (Imaging Sciences International, Hatfield, PA). Data were analyzed using Student’s t-tests and Tukey HSD tests. Results: For the analysis of age, data were divided into four groups: 12–17, 18–29, 30–49, and ≥50 years. The data were also divided into two groups by gender. Axial and coronal image measurements were also divided into right and left. There was a statistical difference compared with females and males (p<0.05). In the coronal plane, the right region showed significant differences in measurements between the groups (p<0.05). In the axial plane, there was no statistically significant difference between them (p>0.05). The differences between the groups in the left region in the axial plane measurements were significant (p<0.05). Conclusions: Using CBCT imaging superimposition of anatomical structures can be eliminated. It is important that determine that the size of the mental foramen. This study is a retrospective study using CBCT from patient and find that the size of the mental foramen. How to cite this article: Falakaloglu S, Veis A.

Aim: Periodontal diseases are a major worldwide and is considered to be one of the most common oral pathologies. A large portion of periodontal pathologies are affected by a variety of factors genetic, socio-economic status, smoking, oral hygiene and lifestyle. The relationship between smoking and periodontal disease attracting more and more interest in the last 10-15 years. This study was planned to determine whether there is a relationship between smoking habits and periodontal status. Methodology: In this study, 372 individuals were evaluated between the ages 12-79. These individuals divided into 7 groups according to age, including 12-19, 20-29, 30-39, 40-49, 50-59, 60-69, and 70-79. CPITN scores and whether or not cigarette smoking habits of all individuals were recorded. Daily cigarette consumption was evaluated 0, occasionally, 1-10, 11-20 and more than 20.  Results: In our study, no significant statistical difference was found between the age groups and gender (p>0.05). There is a relationship proportional to the age and periodontal disease (p<0.05). Periodontal status of individuals who smoke analyzed, although individuals who smoke have higher periodontal scores, statistically significant relationship was not found between the two groups. Conclusions: Examined the periodontal status of the individuals included in the study, there is no difference between smokers and nonsmokers with individuals, despite the periodontal scores were higher in smokers. It is suggested that oral hygiene education would be effective in the rate of smoking and periodontal health. How to cite this article: Saribas E, Acun Kaya F, Dogru AG, Talo Yildirim T.

Aim: A thorough understanding of root and canal anatomical variations is essential for achieving successful endodontic treatment. Literature continues to demonstrate complex root and canal anatomical variations in mandibular third molars which are sometimes in close approximation to the inferior alveolar canal. Methodology: A 26-year-old male patient was referred for endodontic treatment of a three-rooted mandibular third molar with a dilacerated distal root and close approximation to the inferior alveolar canal. A cone beam computed tomography was performed to assess the root and canal anatomical variations together with the inferior alveolar canal. Conventional endodontic treatment was performed using a rotary nickel-titanium file system, and the canals were then obturated using a cold lateral condensation technique. Results: The endodontic treatment procedures were performed successfully and in the follow-up visit, the tooth was asymptomatic. Conclusions: Despite limited accessibility and challenges during root canal treatment procedures, retaining every functional component of the dental arch, including mandibular third molars, is an essential goal of contemporary dental practice.  How to cite this article: Sharawy WW, Ahmed HMA.

In the field of restorative dentistry, the use of composites has become widespread with increasing aesthetic demand. Nowadays the composites are divided into various classes depending on the type and size of the filler particles. Apart from this, many new composites have been produced in order to protect the healthy tooth structure, to reduce microleakage and secondary caries formation, to reduce marginal pigmentation and postoperative sensitivity together with developments in technology. The aim of this review is to improve the clinical performance and to evaluate new composite resins that will provide more selection criteria for dentists.
