Despite substantial improvements in head and neck squamous cell carcinoma (HNSCC) treatment, the major obstacle to long-term survival remains disease recurrence. Salvage options are often limited due to prior therapy and the escalated morbidity of retreatment. The costs of treatment must be measured against the anticipated quality and quantity of life recovered, even with resectable disease. Th...

Two main nonsurgical endoscopic approaches for ablating dysplastic and early cancer lesions in the esophagus have gained popularity, namely, radiofrequency ablation (RFA) and cryospray ablation (CSA). We report a uniquely suited endoscopic and near-microscopic imaging modality, three-dimensional (3D) optical coherence tomography (OCT), to assess and compare the esophagus immediately after RFA a...

INTRODUCTION Root-end preparation and restoration with an endodontic material are required when nonsurgical endodontic retreatment has failed or is impossible. The present clinical study reports the treatment outcomes of periradicular surgery using calcium-enriched mixture (CEM) cement. MATERIALS AND METHODS A prospective outcome study of periradicular surgery using CEM was conducted on 14 pe...

INTRODUCTION The objective of this study was to compare the outcomes of initial nonsurgical root canal therapy for different tooth types provided by both endodontists and other providers. METHODS By using an insurance company database, 487,476 initial nonsurgical root canal therapy procedures were followed from the time of treatment to the presence of an untoward event indicated by Current De...

A prospective in vivo investigation was conducted to determine radiographic and clinical factors associated with contemporary nonsurgical endodontic retreatments. Approximately 1,100 failing endodontically treated teeth were screened to determine an appropriate treatment plan. Using magnification, 337 consecutive retreatment cases were evaluated and treated. The vast majority of the retreated c...

Clinicians frequently encounter endodontically treated teeth that contain silver points within their roots. If endodontic treatment is failing, the need arises to remove this metallic obstruction to facilitate successful nonsurgical retreatment. For the retrieval of these obstructions, most of the methods suggest creating and enlarging a space around the obstruction to loosen it before its retr...

Dentists and patients are facing a perplexity between saving a compromised tooth through endodontic treatment and restoration or by extraction and replacement with an implant. The purpose of this paper was to compare the success rates of these two treatments. Success was measured as the longevity of the tooth or implant. Studies which met strict inclusion criteria to ensure best evidence were i...

Biopsy reports from 150 periradicular tissue specimens obtained from teeth refractory to nonsurgical endodontic therapy were reviewed. The specimens were submitted by postdoctoral dental students in the Department of Endodontics, and the biopsy reports were prepared by oral pathologists at the University of Texas Health Science Center at San Antonio. The study found that 59.3% of the periradicu...

successful endodontic treatment requires thorough knowledge regarding each root canal system of any tooth and probability of extra canals should be considered. second maxillary molar with two palatal root canals is not frequent and its incidence reported in literatures is about 0.4–2%. the present case report describes non-surgical retreatment of maxillary second molar with two palatal root can...
