Success Of Surgical Endodontics At West Virginia University

The ultimate goal of conventional root canal therapy is the retention of the treated tooth as a functional member of the masticatory system with healthy periapical and periodontal tissues. The dentist must reduce or eliminate toxic or irritating substances from within the root canals to levels within the physiologic limits of repair of each patient. Although root canal therapy has a high success rate, all cases are not successful, and practitioners must continue to examine their treatment resutls to eliminate any variables which can contribute to failure. An evaluation of treatment results during twenty-year period at the West Virginia University School of Denistry was conducted to calculate the success to failure ratio and to identify those variables which can affect the treatment prognosis.

Abstract: This doctorial thesis begins with a systematic review on clinical studies on single-visit and multiple-visit non-surgical endodontic treatment. The review found that neither single-visit treatment nor multiple-visit treatment could guarantee the absence of postoperative pain. Since the study design of many studies displays significant limitation, and the materials and equipment used in endodontic treatment have dramatically changed in recent years, prospective randomised clinical trials are needed to further verify the postoperative pain and success rate of single-visit versus multiple-visit endodontic treatment. This study also performed a systematic review on clinical studies on core-carrier obturation. A meta-analysis concluded that the success rate of endodontic treatment using core-carrier obturation is high (79%), and the incidence of postoperative pain is low (11%). Most teeth (87%) had adequate adaptation using core-carrier obturation material but one third of them had overfilling. A questionnaire survey was conducted to investigate the preference for single-visit and multiple-visit endodontic treatment among the 16 registered endodontists and 800 randomly selected general dentists in Hong Kong. Eight endodontists and 429 general dentists returned their questionnaires and the results found most endodontists (88%) and general dentists (93%) preferred offering multiple-visit treatments. The two commonest reasons for choosing multiple-visit treatment for both endodontists and general dentists were the positive effects of inter-appointment medications and that the tooth to be treated had doubtful prognosis. Three randomised clinical trials were performed in this study at two clinics, one in The University of Hong Kong (HKU) in Hong Kong and the other in Peking University (PKU) in Beijing. The first clinical trial compared the time in performing non-surgical endodontic therapy with or without the use of a magnifying loupe. Ninety-six teeth were treated with a magnifying loupe and 86 teeth were treated without a magnifying loupe. The results found the use of a magnifying loupe could significantly reduce the endodontic treatment time. The results also showed that treatment time was associated with preoperative pain, number of root canal, number of treatment visit, experience of operator and site of treatment (HKU or PKU); but not associated with age, gender, tooth vitality, or the presence of apical radiolucency or sinus tract. The second clinical trial compared the incidence of post-obturation pain at one and seven days after single-visit and multiple-visit non-surgical endodontic treatment. A total of 538 teeth from patients attending were evaluated. The result found single-visit or multiple-visit endodontic treatment had no difference in their incidence of postoperative pain, which was not uncommon after one day (29%) but was infrequent (5%) after seven days. The third clinical trial was performed at HKU clinic to compare the success rate, prevalence of postoperative pain and chairside time of single-visit and multiple-visit endodontic treatment. A total of 220 teeth were followed up for at least 18 months. The average follow-up period was 29 months. The results found that the success rate and prevalence of postoperative pain of single-visit or multiple-visit treatment had no significant difference. The chairside time for single-visit treatment was shorter than multiple-visit treatment.

This book is intended for the general practitioner with a special interest in endodontics, students undergoing specialist training and specialists alike. Endodontic retreatment poses many practical challenges. Advances in scientific knowledge and the integration of operating microscopes into endodontic practice have seen the possibilities for predictable endodontic treatment and retreatment expand dramatically. Advanced Endodontics: Clinical Retreatment describes many of the techniques and methods available for practitioners who wish to undertake the planning and treatment of complex endodontic retreatment. The text is referenced to provide a comprehensive but discreet source of scientific evidence, principles and further reading. Knowledge and theory are important in managing complex endodontic retreatment cases, but cannot be a substitute for essential practical and clinical experience. These skills need to be learned and practiced. Novices should always start with the simplest cases and never proceed beyond their confidence or skill level. Numerous practical courses are available for instruction on retreatment techniques and attendance on them can only be encouraged.

Microsurgery in Endodontics provides the definitive reference to endodontic microsurgery, with instructive photographs and illustrations. Provides a definitive reference work on endodontic microsurgery Includes contributions from pioneers and innovators in the field of microsurgical endodontics Describes techniques for a wide range of microsurgical procedures Includes more than 600 instructive illustrations and photographs

Complex endodontic problems that require further work on the part of the clinician can be time-consuming and problematic. This highly illustrated text, from one of the authors of the very successful Endodontics: Problem-Solving in Clinical Practice, tackles these difficult aspects and guides the practitioner through the problems and procedures involved. The only monograph on this specific problem area, Advanced Endodontics will be of interest to endodontists, general dental practitioners with a special interest in endodontics, and postgraduates in restorative and endodontic specialties.

This book presents up-to-date recommendations for the prevention, diagnosis, and management of complications in endodontic surgical procedures, based on the best available scientific evidence. Common risks such as wound healing impairment, infection and bleeding are discussed and specific complications related to endodontic surgery, such as maxillary sinus involvement and damage to adjacent neurovascular structures, are reviewed. For each step of endodontic surgical procedures, surgical goals and possible outcomes are reviewed. Preoperative, intraoperative and postoperative risk factors for complications are identified and treatment options presented. Helpful decision-making algorithms, tables and flow charts complement the reader-friendly text.
