case selection and treatment plan are important aspects of endodontic treatment. dentists should organize the treatment plan based on their knowledge, abilities, skills and more importantly the patients’ preference and dentition. indubitably, the treatment plan for each patient is exclusive and “tailor-made” and cannot be used for all patients. dentists’ self-estimation of their abilities opens...

this case series aims to comprehensively introduce intentional replantation with a focus on its indications and case selection in endodontics. in all represented cases, calcium enriched mixture (cem) cement is used for root-end filling. this case series demonstrates twenty cases of ir and extraoral root-end resection and filling with cem cement. all the selected teeth had a failed endodontic tr...

Autotransplantation provides the possibility of a natural tooth rather than a prothesis or an osseointegratedimplant to replace a missing tooth. The indications for autotransplantation are wide, but careful patient selection coupled with an appropriate technique is a prerequisite for a good functional and esthetic outcome. This article discusses about the indications for autogenous tooth transp...

We explore the functional, developmental, and evolutionary processes which are argued to produce tooth reduction in the extinct marine reptile Stenopterygius quadriscissus (Reptilia: Ichthyosauria). We analyze the relationship between mandible growth and tooth size, shape, and count, to establish an ontogenetic trend. The pattern in S. quadriscissus is consistent with hypotheses of tooth size r...

The purpose of this survey was to determine the knowledge and awareness about the principles of tooth shade selection among final year dental students, interns, general dentists and specialist prosthodontists/restorative dentists in Riyadh, Saudi Arabia. A self-administrative questionnaire especially designed for this study, was distributed among a conveniently selected sample. A total of 292 (...

objectives: tooth loss appears to have an important role in the loss of mastication and esthetics. the aim of this systematic review was to investigate the prevalence of tooth loss and edentulism in the iranian population. methods: studies reviewed in this article were primarily identified via search of the online bibliographic databases including pubmed and iranian biomedical journals, by usin...

Australopithecus anamensis is the earliest known species of the Australopithecus-human clade and is the likely ancestor of Australopithecus afarensis. Investigating possible selective pressures underlying these changes is key to understanding the patterns of selection shaping the origins and early evolution of the Australopithecus-human clade. During the course of the Au. anamensis-afarensis li...

Teeth in Cervidae are permanent structures that are not replaceable or repairable; consequently their rate of wear, due to the grinding effect of food and dental attrition, affects their duration and can determine an animal's lifespan. Tooth wear is also a useful indicator of accumulative life energy investment in intake and mastication and their interactions with diet. Little is known regardin...
