Aim: The aim of this study was to evaluate the effectiveness of two instrumentation and irrigant techniques in smear-layer removal from root canals. Methodology: Thirty single-rooted teeth were randomly divided into two groups. Group 1 (continuous irrigation) was prepared using Self-adjusting file, and group 2 (manual irrigation; conventional needle irrigation) was prepared using with ProTaper file system. Groups were irrigated using sodium hypochlorite (5%) as an initial irrigant following MTAD in a closed system. Canals were bisected and examined by scanning electron microscopy. Smear layers were evaluated using a five-point scoring system with 2500x magnification. Results: Smear layers were eliminated in the coronal, middle, and apical thirds of the root canal, respectively, in 93%, 80%, and 60% of samples in the group 1, and 67%, 60%, and 27% in the group 2, of the coronal, middle, and apical thirds of the root canals, respectively. Evaluation by SEM showed continuous irrigation differed not-significantly from the manual irrigation group in all areas (P >0.05). Conclusions: Smear layer can be removed properly with suitable irrigation methods. How to cite this article:  Kaya S.

Aim: Diastemas can be treated using periodontal, surgical, orthodontic, or prosthetic procedures. Composite laminate veneers can be applied to reduce or eliminate diastemas and represent a good aesthetic non-invasive alternative for these patients. This study presents the treatment results of 10 patients with diastemas between the anterior teeth of the maxilla and mandible with composite veneers. Methodology: Ten patients with diastemas between the anterior maxillary and mandibular teeth complaining of esthetic problems were treated at the Department of Operative Dentistry, University of Dicle. The periodontal health of the patients was acceptable and no caries were detected. Patients were informed of the treatment choices and composite resin veneers were selected as the better approach for each case. The presence of a diastema causes esthetic problems, especially in adolescents. Prosthetic and conservative methods are usually used to treat diastemas because these approaches are minimally invasive. The direct laminate technique has the advantages of low cost, treatment reversibility, and easy repair of the restoration intraorally. The direct composite laminate technique has become more effective because of improvements in adhesive dentistry. Conclusion: This study describes a direct composite laminate technique for the restoration of the anterior teeth of 10 patients with diastemas. These restorations were conservative and provide an inexpensive, one-visit aesthetic treatment for anterior teeth.  How to cite this article:  Bahşi E, Callea M, İnce B, Montanari M, Dallı M, Batteli F, Akdoğan M, Gabriella C, Toptancı İR, Gabriela P, Yavuz İ.

Aim : This case report describes the use of a surgical guide in a crown-lengthening procedure to improve the aesthetics of the anterior interdental papillae in an adult female patient. Methodology: A 40-year-old female underwent a crown-lengthening procedure with guidance provided by a surgical template to correct unsatisfactory aesthetics in the anterior gingiva and prosthesis. Results: The patient’s functional and aesthetic expectations were met successfully with interdisciplinary treatment, including surgical crown lengthening and the placement of all-ceramic restorations. Conclusions: This case showed that satisfactory anterior aesthetics can be achieved by comprehensive examination, careful planning of treatment employing a surgical guide, and prosthodontist–periodontist teamwork, even in the complete absence of interdental papillae.  How to cite this article:  Kılıç D, Alkan BA, Kılıç K.

Endoperiodontal lesions are characterized by the presence of periodontal and pulpal disease within the same dental element. Periodontal and pulpal tissues are related to each other by lateral and accessory canals, the apical foramen, and the dentinal tubules. In the dental literature, whether periodontal disease affects pulpal disease or vice versa remains controversial. Pulpal disease is often accepted to cause periodontal disease. The treatment of endodontic-periodontal combined lesions requires both endodontic therapy and periodontal regenerative procedures. The success rate of treatment comprising only an endodontic procedure for such lesions is low. Periodontal regenerative therapy has been used widely to regenerate periodontium lost due to periodontal disease. This therapy is also very successful during the management of endodontic-periodontal lesions.  How to cite this article:  İzol BS, Doğru AG, İpek F, Günay A.
