Occlusion is commenced by contact of a tooth with an opposing tooth and is the mechanical force working against the periodontal ligament (PDL). Our recent study indicated that occlusion regulated tooth-root elongation occurs during root development in rat molars. Using a non-occlusal model established to directly examine the effects of the absence of occlusion in developing first molars of uppe...

The purpose of this study was to analyze the survival rate in autotransplanted premolars with complete root formation in dental clinics. Participating dentists were requested to provide information on transplantations they had undertaken between 1 January 1990 and 31 December 2010. Data on a total of 708 teeth from 637 patients were collected. Data for other tooth types and for teeth with incom...

Dental scientists are eagerly embracing regenerative medicine using tissue engineering technology. Enamel, one component of teeth, is the hardest tissue in the body. It cannot regenerate by itself, because it is formed by a layer of ameloblasts that is lost by the time the tooth crown has completely formed. Although the enamel is spent during lifetime, it is vulnerable to wear, damage, and deca...

objective: osteopontin (opn) has been proposed to play a role in bone resorption. with regard to bone and cementum/dentin structural and histological similarities, it was hy-pothesized that expression of this gene might be increased in resorptive lacunae during orthodontic tooth movement. materials and methods: fixed nickel-titanium closed coil springs (dentaurum ® ) capa-ble of delivering appr...

single rooted primary mandibular first molar is a rare developmental anomaly. literatures reveal that failure of invagination of hertwig's epithelial root sheath leads to this unusual root form. thorough knowledge of root canal morphology and anatomical variations of primary teeth can help a pediatric dentist in successful root canal treatment. hereby, we describe two cases of primary mandibula...

an accurate diagnosis of the morphology of the root canal system is a pre-requisite for successful root canal treatment. frequently, root canals are left untreated because the clinicians fail to identify their presence, particularly in teeth that have anatomical variations or additional root canals. in this report a maxillary lateral incisor with two roots has been described.

Apical periodontitis in permanent children's teeth with incomplete root development is a challenge for endodontists to treat. It is important that highly efficient therapeutic methods and biologically valuable therapies be developed to prevent the loss of these teeth. The AIM of the study was to review modern literature on revascularization of non-vital permanent teeth with incomplete root deve...

autogenous tooth transplantation (att) is a simple and reasonable choice for replacing the missing teeth when a proper donor tooth is available. this report presents a case of successful att of a maxillary right third molar for replacement of mandibular right second molar with a concomitant endodontic-periodontal disease. the mandibular second molar was believed to be hopeless due to a severe d...

O ne way to attempt periodontal regeneration is to mimic the biologic processes involved in nascent tooth development, especially the development of the root and the supporting tissues. The EMDOGAIN® (BIORA AB, Malmö, Sweden) concept is based on the discovery that enamel matrix proteins are not only involved in enamel formation but also play a key role in the formation of acellular cementum [1,...
