Outcome assessment of endodontic treatment is critical for appropriate case selection and treatment planning. However, reports on outcomes of nonsurgical endodontic treatment vary considerably. Epidemiological studies done in a large patient population and over a long follow-up period can provide the clinician with useful tools for clinical decision-making and assessment of tooth prognosis. In ...

AIM The aims of this report are to present three cases of autotransplantation along with a review of the indications, selection criteria for patient donor and recipient sites, and the major steps in the surgical procedure. BACKGROUND Autogenous tooth transplantation, or autotransplantation, is the surgical movement of a tooth from one location in the mouth to another in the same individual. I...

INTRODUCTION Clinicians are regularly confronted with difficult choices. Should a tooth that has not healed through nonsurgical root canal treatment be treated through endodontic microsurgery or be replaced using a single implant? Acquiring complete, unbiased information to help clinicians and their patients make these choices requires a systematic review of the literature on treatment outcomes...

This article presents the successful surgical management of a failed mineral trioxide aggregate (MTA) orthograde obturation of a tooth with a history of impact trauma and perforated internal root resorption. A symptomatic maxillary lateral incisor with a history of perforation due to internal root resorption and nonsurgical repair using MTA was referred. Unintentional overfill of the defect wit...

AJXHOUGH the importance of Carabelli's cusp in phylogenetic studies and for primary racial classification is generally acknowledged, the exact significance of this variable trait remains obscure.and controversial (MOORREES, 1957; KORENHOF, 1960). In this report we examine the " progressive " versus " regressive " aspect of the controversy on which opinions have remained sharply divided for almo...

The purpose of this paper was to summarize the findings of a literature review on the use of peroxide-based tooth-whitening agents in children and adolescents. Safety considerations, including localized adverse effects and toxicological concerns, are described. Oral findings include: (1) 1 in every 2 to 3 patients may experience tooth sensitivity and/or gingival irritation after bleaching treat...

Planetary gearboxes are widely used in aerospace, automotive and heavy industry applications due to their large transmission ratio, strong load-bearing capacity and high transmission efficiency. The tough operation conditions of heavy duty and intensive impact load may cause gear tooth damage such as fatigue crack and teeth missed etc. The challenging issues in fault diagnosis of planetary gear...

PURPOSE This study was performed to obtain a quantitative evaluation of the cortical and cancellous bone graft harvestable from the mental and canine regions, and to evaluate the cortical vestibular thickness. MATERIALS AND METHODS This study collected cone-beam computed tomographic (CBCT) images of 100 Italian patients. The limits of the mental region were established: 5 mm in front of the m...

Traditionally, thick enamel has often been used to infer durophagy (i.e., hard nut and seed consumption) in extinct hominins. These inferences are based on the hypothesis that thick enamel is primarily an adaptation to prevent tooth fracture or chipping resulting from high-stress loads produced during the mastication of large hard foods. An alternative view argues that thick enamel may aid in m...
