BACKGROUND We investigated the clinical and radiographic outcomes of autotransplanted teeth over a follow-up period of 2 to 8 years, and summarize the findings of other relevant studies with regard to the primary factors that influence a good prognosis in such patients. METHODS Twenty-three patients (6 men, 17 women) who attended Tanggu Stomatological Hospital, Tianjin, China, from 2008 throu...
The origin of baleen whales (Mysticeti), the largest animals on Earth, is closely tied to their signature filter-feeding strategy. Unlike their modern relatives, archaic whales possessed a well-developed, heterodont adult dentition. How these teeth were used, and what role their function and subsequent loss played in the emergence of filter feeding, is an enduring mystery. In particular, it has...
introduction:there are conflicting reports on the effects of surgical removal of impacted mandibular third molars on the periodontium of the adjacent teeth. the aim of this study was to compare the condition of the periodontium six months after extraction of impacted mandibular third molars with baseline values. methods: fifty patients with mesioangular impacted mandibular third molarsparticipa...
introdouction:tooth eruption is recognized as an important aspect of human growth and development. it can be influenced by a number of factors, and it may reflect the general development of a child’s body. the purpose of this study was to determine the age at which the first primary tooth erupted and its relationship with height, weight and head circumference in 3-15-month children in the city ...
Background and purpose: Assessment of tooth length has an important role in success and failure of dental treatments. As yet periapical radiography has been used for the assessment of tooth length causing high x-ray exposure, long time and patient discomfort. Using panoramic radiography can resolve these problems. The major disadvantage of panoramic radiography is monotonous magnification. The ...
Background: In comparison with implant treatment, autotransplantation offers potential benefits associated with the use of natural teeth. The periodontal benefits of autotransplantation include bone regeneration and reestablishment of the alveolar ridge, indicating that the procedure can be effective in regions with severe bone loss. Case Description: A 30-year-old man presented with a chief co...
INTRODUCTION This systematic review evaluated root resorption as an outcome for patients who had orthodontic tooth movement. The results could provide the best available evidence for clinical decisions to minimize the risks and severity of root resorption. METHODS Electronic databases were searched, nonelectronic journals were hand searched, and experts in the field were consulted with no lan...
AIM To ascertain the impact of routine application of the informed consent form at the primary dental care units of the Galician Health Service. STUDY DESIGN Non random selection of consecutive patients seeking tooth extraction between 9 January and 7 March 2007 at the dental care units of Burela, Praza do Ferrol and Viveiro (Lugo). The study included sociodemographic, clinical, utilization, ...
The regeneration of immature permanent teeth following trauma could be beneficial to reduce the risk of fracture and loss of millions of teeth each year. Regenerative endodontic procedures include revascularization, partial pulpotomy, and apexogenesis. Several case reports give these procedures a good prognosis as an alternative to apexification. Care is needed to deliver regenerative endodonti...
Introduction Regenerating a tooth completely in human oral cavity is not achieved by current studies yet. Here, we have conceived a man-induced method to construct a teeth germ which might be used to regenerate a tooth in vivo. This idea was generated by traits of the development of the compound odontoma, a benign tumour of tooth malformation. This is a kind of developmental tooth malformation,...
