Dental trauma is more common in young patients and its sequelae may impair the establishment and accomplishment of an adequate treatment plan. This paper reports a case of complicated crown-root fracture in a young adult that was treated using adhesive tooth fragment reattachment and orthodontic root extrusion. Considering the time elapsed to follow up, the fracture extension, the amount of remaining root portion and the patient's low socioeconomic status, the treatment approach proposed for this case provided good functional and aesthetic outcomes. Clinical and radiographic results after 2 years were successful. This case report demonstrates the importance of establishing a multidisciplinary approach for a successful dental trauma management.
Although the search for the ideal bone substitute has been the focus of a large
number of studies, autogenous bone is still the gold standard for the filling of
defects caused by pathologies and traumas, and mainly, for alveolar ridge
reconstruction, allowing the titanium implants installation.ObjectivesThe aim of this study was to evaluate the dynamics of autogenous bone graft
incorporation process to surgically created defects in rat calvaria, using
epifluorescence microscopy.Material and methodsFive adult male rats weighing 200-300 g were used. The animals received two
5-mm-diameter bone defects bilaterally in each parietal bone with a trephine bur
under general anesthesia. Two groups of defects were formed: a control group
(n=5), in which the defects were filled with blood clot, and a graft group (n=5),
in which the defects were filled with autogenous bone block, removed from the
contralateral defect. The fluorochromes calcein and alizarin were applied at the
7th and 30th postoperative days, respectively. The animals were killed at 35
days.ResultsThe mineralization process was more intense in the graft group (32.09%) and
occurred mainly between 7 and 30 days, the period labeled by calcein (24.66%).ConclusionsThe fluorochromes showed to be appropriate to label mineralization areas. The
interfacial areas between fluorochrome labels are important sources of information
about the bone regeneration dynamics.
The purpose of this case report / case series was to analyze the pattern of alveolar bone repair after extraction with the use of a collagen membrane associated or not with lyophilized bovine bone (Bio-Oss). The sample consisted of six adult patients, aged from 40 to 60 years, with indication of extraction of the upper incisors and subsequent rehabilitation with dental implants, three participants were randomly distributed in the following groups: Test - Bio-Oss associated with collagen membrane absorbable; Control - blood clot associated with an absorbable collagen membrane. Alveoli with significant bone loss, probe greater than 4 mm, uncontrolled systemic changes and smoker were excluded. The less traumatic extractions, followed by anti-inflammatory and antibiotic protocol. Computed tomography images from the preoperative time (T0) and after 4 months (T1) were used to measure bone filling. The data were compared using the T test, considering a 5% significance level. Less resorption was observed in the test group (p = 0.002). The technique of preserving the alveolar ridge with Bio-Oss and absorbable membrane was satisfactory to prevent changes in the contour of the tissue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
