alveolar ridge resorption has long been considered an unavoidable consequence of tooth extraction. while the extent and pattern of resorption is variable among individuals, there is a progressive loss of ridge contour as a result of physiologic bone remodeling. even today, with best modalities of tooth preservation, there is a group of elderly individuals who do not benefit from modern preventiv...

Traumatic dental injury is considered a public dental health problem because of a high childhood incidence, high treatment costs, and prolonged treatment time. Although management guidelines for traumatized teeth have been outlined, tooth loss following trauma is occasionally unavoidable. Here, we describe the successful interdisciplinary management of a traumatized central incisor in an 11-yea...

Traditionally, when a root-originated fracture (ROF) was diagnosed in an endodontically treated tooth, the tooth was scheduled for extraction. However, modern endodontics offers new treatment options to manage and maintain certain ROF teeth. The decision of whether to extract a ROF tooth and substitute it with a dental implant, or to implement a more conservative management approach by attempti...

In order to investigate tooth development, several cell lines of the dental epithelium and ectomesenchyme have been established. However, no attempt has been reported to regenerate teeth with cell lines. Here, we have established several clonal cell lines of the dental epithelium from a p53-deficient fetal mouse. They expressed specific markers of the dental epithelium such as ameloblastin and ...

Implant insertion is an alternative to classical treatment with bridges after tooth extraction or traumatic tooth loss in the anterior and premolar region of the upper and lower jaw. Nevertheless both types of prosthetic treatment inhere major gingival aesthetic pitfalls by physiological vertical and horizontal resorption. Aim of the study was to investigate if the immediate insertion of root a...

Endodontic treatment of a tooth in its present state offers a high degree of success for most cases, but it leaves the tooth in a physiologically “dead” state. Regenerative endodontics is an emerging field which is trying to regenerate natural tissues associated with the tooth generated by nature. This article reviews the present status of regenerative endodontics, why is it important to regene...

To perform advanced periodontal therapy to save a natural tooth or to extract it and place an implant-which is best? Several considerations need to be made to make the proper decision. Endodontic conditions, proper reconstruction of a devitalized tooth, and the possibility of correct prosthetic treatment are all factors to be considered. From a strictly periodontal point of view, in the presenc...

Coronal fractures of permanent dentition are the most frequent type of dental injury. If the original tooth fragment is retained following fracture, the natural tooth structures can be reattached using adhesive protocols. The development and use of fiber-reinforced composite root canal posts make possible of the reattachment of the crown esthetically. This case report presents a clinical techni...

Teeth are a classicmodel system of organogenesis, as repeated and reciprocal epithelial and mesenchymal interactions pattern placode formation and outgrowth. Less is known about the developmental and genetic bases of tooth formation and replacement in polyphyodonts, which are vertebrates with continual tooth replacement. Here, we leverage natural variation in the threespine stickleback fish Gas...

No information currently exists on the floristic structure and richness of Artemisia alba scrubs in Romania their regional/local environmental drivers. We aimed to fill these knowledge gaps by also considering physiognomically similar communities from Hungary, Serbia Bulgaria. A total 89 phytosociological relevés, including 43 performed Romania, were analysed through clustering, constrained ord...
