- Advanced tools and Techniques in Dental Science
Syrian Private University,Syria
Talal Al-Nahlawi has graduated from Faculty of Dentistry-Damascus University 1999; he completed his post graduate diploma in endodontics in 2001, Master of Science in 2004, and PhD degree in 2009 from Damascus University. Since then he became an assistant professor at Operative dentistry and Endodontics department at Damascus and Syrian Private Universities. He was conferred into the title of associate professor in 2015. He has a private practice in Damascus and United Arab Emirates limited to Endodontics. He lectured in many national and international dental meetings (Syria, Canada, Brazil, Iraq, Turkey, Egypt, United Arab Emirates, India, Lebanon, and South Africa).
The accident of endodontic files separation is considered the most annoying accident that can face the dentist during his/her daily endodontic practice. The management of such accident needs sufficient understanding of the type and geometry of broken file, location and size of the file, amount of canal disinfection before file separation, and length with amount of engagement with canal walls. After thorough clinical and X ray examination, treatment plan must be based upon three options: bypassing, removal, or leaving the broken file inside the canal with monitoring. The objective of this presentation is to highlight the factors contributing to file separation and how to avoid it along with a description of a novel technique for bypassing a broken file, and how to remove a broken file when indicated through many clinical cases with illustrations and videos.

Background: Resin composite is considered the first choice for restoration of permanent teeth. Low cost, adhesion to tooth structure and being biologically acceptance makes it material of choice in most of the cases. However, sophisticated restoration procedure, moisture sensitivity and difficult manipulation limit its application as a direct restoration especially in cases of badly decayed/broken teeth.Case Report: In this report the author a case of indirect composite restoration for right maxillary molar. The tooth was badly carious and symptoms were classical for chronic pulpitis. Root canal treatment was done in one visit. Because the crown of the tooth has lost most of its structure, treatment plan was shifted from direct to indirect composite restoration. The cavity was filled with self-adhesive core build up dual-cure material and prepared with high speed handpiece to remove any undercut and make the cavity divergent occlusally. Impression was made, poured with stone and sectioned to obtain separated die. Teflon tape was used as a separating layer. Nano-filled resin composite was applied incrementally to build up the tooth in normal anatomy and contour followed by finishing and polishing. The restoration was cemented on the prepared tooth using dual-cure resin cement, high spots were checked and relieved, and the restoration was re-polished intra-orally. Periodic follow up visits up to eight months showed effective clinical performance with patient satisfaction.Conclusion: Indirect Composite Restoration provides luxury of application, manipulation and curing of composite outside the oral cavity. It offers better marginal assessment for the restoration and optimum contouring.
