Children and young adults often have tooth loss due to congenital tooth deficiency, trauma, or caries. Autotransplantation has many benefits. The transplanted tooth can be moved orthodontically, maintains alveolar bone growth potential during eruption, and functional periodontal ligament function also permits tooth eruption, allows the defected areas to be filled with the bones; gingival contour is much more successful than the one obtained with prosthesis. In this paper, treatment steps and follow-up results of autotransplantation case supported with biostimulation are mentioned...

Rhein, a glucoside chemical compound found in a traditional Chinese medicine derived from the roots of rhubarb, induces cell apoptosis and is considered to have high potential as an antitumor drug. Several previous studies showed that rhein can inhibit cell proliferation and trigger mitochondria-related or endoplasmic reticulum (ER) stress-dependent apoptotic processes. However, the side effects of rhein on pre- and post-implantation embryonic development remain unclear. Here, we show that rhein has cytotoxic effects on blastocyst-stage mouse embryos and induces oxidative stress and immunotoxicity in mouse fetuses...

Introduction: Treatments with dental surgery seek to displace tooth to the correct position within the dental arch. Objective: To report a clinical case that took advantage of an unerupted third molar. Case history: A male patient, 18 years of age, was referred by his dentist to evaluate the third molars. The clinical exam revealed no visible lower third molars. The computed tomography (CT) exam showed the presence of a supernumerary tooth in the region of the mandibular ramus, on the left side, and impaction of the third molar, which was causing root resorption on the second molar, thus making it impossible to remain in the buccal cavity...

Alberto Consolaro, Débora de Almeida Bianco
Root resorptions caused by orthodontic movement are not supported by consistent scientific evidence that correlate them with heredity, individual predisposition and genetic or familial susceptibility. Current studies are undermined by methodological and interpretative errors, especially regarding the diagnosis and measurements of root resorption from orthopantomographs and cephalograms. Samples are heterogeneous insofar as they comprise different clinical operators, varied types of planning, and in insufficient number, in view of the prevalence of tooth resorptions in the population...

Maxillary canines are the most commonly impacted teeth, second only to third molars. Various treatment methods may be used to recover impacted maxillary canines. This is a report of a 14-year-old girl with a severely malpositioned impacted right maxillary canine which accompanied severe root resorption of adjacent tooth, treated by autotransplantation with a computer aided rapid prototyping model as a surgical guide. This case report demonstrates that autotransplantation can be a reliable treatment alternative, in cases with a severely malpositioned impacted canine, providing acceptable prognosis...

INTRODUCTION: The hypothesis of this study was that multiple factors are dominant in causing external apical root resorption (EARR). The objective of this investigation was to better understand the clinical factors that may lead to EARR. METHODS: Maxillary cone-beam computed tomography scans of 18 subjects who were treated with bilateral canine retractions during orthodontics were used to calculate EARR. The subjects were treated using well-calibrated segmental T-loops for delivering a 124-cN retraction force and the moment-to-force ratio suitable for moving the canine under either translation or controlled tipping...

INTRODUCTION: The adenomatoid odontogenic tumor (AOT) associated with odontoma has been described as a new entity with overlapping features of adenomatoid-like structures and odontoma. Presentation of the case: We report the second case of AOT associated with odontoma in the posterior maxillary region. A 22-year-old patient presented expansion of the vestibular and palatine cortical wall of maxilla. Radiographic examination and computed tomography confirmed erosion of maxillary walls, root resorption, displacement of a neighboring tooth and radiopacities within the lesion...

BACKGROUND/AIMS: Tooth avulsion consists of the complete displacement of a tooth from the alveolar socket. When immediate replantation is not possible, the avulsed tooth should be kept in a storage medium capable of maintaining the viability of periodontal ligament (PDL) cells on the root surface. However, there is no consensus on the best storage medium able to prevent sequels such as ankylosis and tooth resorption. The aim of this study was to perform a systematic review to evaluate the in vivo effectiveness of different storage media for avulsed teeth...

Orthodontic tooth movement is achieved by the remodeling of the alveolar bone surrounding roots of teeth. Upon the application of orthodontic force, osteoclastic bone resorption occurs on the compression side of alveolar bone, towards which the teeth are driven. However, the molecular basis for the regulatory mechanisms underlying alveolar bone remodeling has not been sufficiently elucidated. Osteoclastogenesis is regulated by receptor activator of nuclear factor-κB ligand (RANKL), which is postulated to be expressed by the cells surrounding the tooth roots...

INTRODUCTION: The absence or presence of root resorption on the surface of a replanted tooth indicates an immune-inflammatory reaction. Recent research even suggests the participation of host predominant immunologic profile on types of resorptions detected on the root surface. Because interleukin 4 (IL-4) is an important anti-inflammatory cytokine, this study aimed to investigate the association of clinical variables and polymorphisms in IL4 with types of resorption of replanted teeth after 1 year of follow-up...

PURPOSE: To study the effect of enamel matrix derivative(EMD) on root repair and tooth movement relapse after orthodontic tooth movement in rats. METHODS: Twenty 10-weeks old male rats were divided into experimental and control group randomly (n=10). 100 g force was exerted to the left maxillary first molars for 14 days and then removed. EMD was injected in rats in the experimental group since appliance was removed. The control group received no injection. Micro-CT was taken to analyze the changes of root resorption volume and distance of tooth movement...

During daily routine oral examinations in a research colony of nonhuman primates (NHPs, Macaca fascicularis), a variety of oral-dental lesions were identified. A dental care program was established based on these findings. Based on the presence of dental clinical signs and their severity, 31 animals were triaged to be examined and treated by a veterinarian. Clinical examination consisted of visual inspection using a periodontal probe/explorer and full or partial mouth dental radiographs. Treatment was performed during the same procedure...

Invasive cervical root resorption (ICR) is the reversible/irreversible loss of tooth structure in the connective tissue attachment zone with unclear etiology. In the present case a history of periodontal surgery was presumed to be the predisposing factor. Early diagnosis and proper treatment may lead to long-term retention of the tooth. The tooth is usually asymptomatic and diagnosis is commonly made as a result of a routine radiographic finding. Cone-beam computed tomography (CBCT) is extremely useful in diagnosis and treatment planning of ICR...
