The aim of this paper was to analyze delayed tooth eruption in two children with cerebral palsy who had severe bruxism and to determine whether treatment could influence tooth eruption and alignment. Extraction of primary teeth was carried out and orthodontic treatment was considered due to severe tooth wear of primary teeth, lack of space, and development of a class III malocclusion.
Analysis was based on clinical examination, photographs, radiographs, and dental casts.
In both patients, early mixed dentition was delayed for more than 5 years. Calcification and root development of posterior permanent teeth corresponded with the chronological age. Root resorption of the severely abraded primary teeth and eruption of their successors were delayed or failed. Eruption of permanent teeth occurred slowly after primary teeth were extracted. Orthodontic treatment succeeded in one patient, achieving a normal overjet in combination with a successful orofacial therapy.
The disturbed exfoliation of abraded primary teeth and failure of tooth eruption of the posterior teeth could be linked to the systemic pathology and to bruxism. At age 20, eruption of the canines and premolars remained questionable. 相似文献

Oral Diseases (2010) 16 , 674–685 Objectives: Tooth extraction has been identified as an important risk factor for bisphosphonate‐induced osteonecrosis of the jaw. Therefore, the main goal of this study was to determine the effects of alendronate on healing of the extraction socket and on interdental alveolar bone after tooth extraction in rats. Materials and methods: Animals were injected subcutaneously with vehicle or alendronate for 3–4 weeks before the first mandibular molar was extracted and these treatments were continued during post‐extraction periods of 10, 21, 35 and 70 days. Mandibles were processed to evaluate healing of the extraction socket and adjacent alveolar bone by assessing bone formation, bone resorption and vascularity by histomorphometric techniques. Results: Alendronate decreased new woven bone formation, blood vessel area, perimeter and number in the extraction socket at 10 days postextraction, but not at later time points. Furthermore, alendronate‐treated rats had increased interdental alveolar bone volume and height only at 10 days postextraction. In addition, a 2.5‐fold increase in the percentage of empty osteocyte lacunae was found in alveolar bone of alendronate‐treated rats only at 10 days postextraction. Conclusions: Alendronate transiently decreases bone formation and vascularity in the extraction socket and delays the removal of interdental alveolar bone after tooth extraction in rats. 相似文献

Objective
Several extrusion techniques have been described to restore teeth with insufficient coronal tooth structure and to avoid their extraction. Still, there is little evidence for a treatment concept combining surgical extrusion using an atraumatic axial extraction system.Materials and Methods
A total of nine patients, each with an iso- or subgingival fractured tooth, were retrospectively examined. Treatment of the damaged tooth comprised an atraumatic forced surgical extrusion performed with an axial tooth extraction system and a more coronal positioning within the socket. The teeth were initially splinted and subsequently restored. The follow-up period was up to 57.1 months and averaged 36.5 (SD: ±13.5) months.Results
All nine teeth were still in situ, without signs of inflammation. During the period of the provisional restoration, six prosthetic complications occurred, which were resolved with little effort, whereas, success rate for the definitive restoration was 100%. No biological complications were observed concerning the root apex or soft tissue. The radiographically measured mean extrusion distance was 3.4 (SD: ±1.0) mm, so that a sufficient prosthetic ferrule could be reestablished.Conclusions
Surgical extrusions using an axial tooth extraction system demonstrate low biological and prosthetic complications rates over observation time.Clinical Significance
The presented extrusion approach preserves soft and hard tissue and is an efficient treatment option for severely destroyed teeth. Saving hopeless teeth by this relatively predictable and feasible procedure has hardly any disadvantages for patients, and in case of failure, an implant or fixed partial denture are still an option. 相似文献7.

BACKGROUND: Bisphosphonates are used widely to manage skeletal disorders resulting from malignancies that destroy bone and from some metabolic bone diseases. A strong association between bisphosphonate treatment and the appearance of painful exposed nonvital bone in the mandible and maxilla after oral surgery has been reported in the last decade. Extensive reviews have appeared in the dental literature regarding bisphosphonate-related osteonecrosis of the jaws (BRONJ), including protocols for diagnosis, management and diagnostic imaging for early detection; feature definition; and determination of extent of the disease. CASE DESCRIPTION: The authors provide three case reports to show the contrast in treatment outcomes and morbidity in patients with BRONJ. The cases involved diagnostic imaging modalities commonly used in the practice of dentistry: panoramic radiography and cone-beam volumetric computed tomography. CLINICAL IMPLICATIONS: These case reports demonstrate the usefulness of dental diagnostic imaging in the detection and management of BRONJ, corroborate the increasing number of reports regarding high levels of morbidity associated with various BRONJ treatments, and underscore the danger of performing invasive dental procedures for patients receiving bisphosphonate therapy. 相似文献

J Oral Pathol Med (2012) 41 : 222–228 Background: Multiple myeloma (MM) and breast cancer (BC) are the two most common diseases associated with bisphosphonates‐related osteonecrosis of the jaws (BRONJ), for which different therapeutical approaches have been proposed. The aim of this study was to compare the clinical behaviour of BRONJ in patients with MM vs. BC and the time of healing in terms of clinical and symptomatological remission, following a standardized therapeutic protocol. Methods: Twenty‐six BRONJ patients (13 men with MM and 13 women with BC) were prospectively enroled and treated with a specific systemic and topical antibiotic therapy. Several predictors of outcome were also evaluated. Results: Nine patients (69.2%) with BC and 10 patients (76.9%) with MM progressed towards a complete clinical remission (CR) in a mean healing time of 183.3 days [SD: 113.7; 95% confidence interval (CI): 95.95–207.7] and 372.0 days (SD: 308.0; 95% CI: 151.7–592.3) (P = 0.776), respectively. The clinical improvement was statistically significant (P = 0.0013 and P = 0.0014), as well as the assessment of pain (P = 0.0015 and P = 0.0015), in MM and BC group, respectively. Cox regression analysis revealed that just triggering events (P = 0.036) were found to be significant predictors of outcome of BRONJ healing. Conclusions: Both groups of cancer patients experienced clinical and symptomatological remission regardless their malignancy, but BC patients earlier than MM patients. 相似文献

Osteo-odontokeratoprosthesis (OOKP) is a technique invented by Strampelli in 1963, in which the patient's own tooth root is used to support an optical cylinder. It uses an autologous tooth-bone-periodontal complex to mount an optical cylinder, which is stabilised by overlying autologous buccal mucosa. OOKP involves two, staged procedures done by ophthalmologists and oral surgeons, and the main contribution from the oral surgeon is during the first stage. To date we have done nine first-stage, and completed eight second-stage, OOKP operations in Japan with a mean follow-up of eight years and 11 months by modifying the original method of the oral surgery. All OOKP procedures were unilateral, and canines were selected as the donor teeth. Patients developed ocular blindness as a result of Stevens-Johnson syndrome, ocular cicatricial pemphigoid, and chemical and thermal burns to the cornea and ocular surface. All eight patients who completed the second stage have been stable, and there have been no major perioperative or postoperative oral complications. The patients' visual acuities were stable with no serious complications. Here we report the technical details of the oral contribution to OOKP. 相似文献

The aim of this study was to compare the safety of tooth extraction in patients receiving direct oral anticoagulants (DOACs) or warfarin without cessation of their antithrombotic treatment. This prospective observational study included 367 patients undergoing tooth extraction (119 receiving DOACs and 248 receiving warfarin). All extractions in DOAC patients were performed 6–7 h after taking DOACs in consideration of the half-life in blood under continued antithrombotic treatment. To examine the potential postoperative bleeding risk related to the time of extraction and the drug concentration of blood, activated partial thromboplastin time (APTT) in dabigatran and prothrombin time (PT) in rivaroxaban were measured three times after administration. A total of 390 tooth extractions were performed: 128 in the DOAC patients and 262 in warfarin patients. Postoperative bleeding occurred in four extractions (3.1%) in the DOAC group and in 23 (8.8%) in the warfarin group. There was no statistically significant difference between the two groups (odds ratio: 2.362, 95% confidence interval (CI) 0.819–6.815, p = 0.112). APTT and PT prolongation in almost all cases decreased with time after taking the medicine. Our findings suggest that interruption of DOAC therapy is not necessary for tooth extraction if the procedure is performed at least 6 h after the last dose. 相似文献

BackgroundTooth extraction in patients exposed to bisphosphonates (BPs) is considered a risk factor for osteonecrosis. The authors evaluated the time to mucosal healing and frequency of osteonecrosis after tooth extraction in participants exposed to BPs.MethodsThe authors compared wound healing after tooth extraction in participants exposed to BPs with that in control participants who had not been exposed to BPs. Variables included age, sex, type of BP therapy (oral or intravenous), BP exposure time and C-terminal telopeptide (CTX) test results. The authors followed up patients weekly or biweekly until healing was complete. They used multivariable analyses to model time to healing in the presence of covariates, and estimates provided hazard ratios (HRs) and 95 percent confidence intervals (CIs) adjusted for all variables in the model.ResultsThe authors enrolled 53 participants with BP exposure and 39 control participants. Postextraction healing was significantly longer in participants exposed to BPs (P < .001) than it was in control participants. One patient (1.9 percent) developed osteonecrosis. A Cox proportional hazards model in which the authors controlled for age, sex and CTX values showed that BP exposure alone significantly (adjusted HR, 0.27; 95 percent confidence interval, 0.16–0.48) increased mucosal healing time.ConclusionsThe study results showed that postextraction healing was impaired in patients exposed to BPs. CTX values were not associated with delayed healing after tooth extraction.Practical ImplicationsPostextraction healing was delayed in patients receiving BP therapy. However, the risk of developing osteonecrosis was low. 相似文献

BACKGROUND: While osteonecrosis of the jaw (ONJ) has been associated with the prolonged use of bisphosphonates (BPs), there is limited information about the risk of ONJ among users of oral BPs or about the magnitude of the risk among users of intravenous (IV) BPs. METHODS: The authors studied medical claims data from 714,217 people with osteoporosis or cancer to identify diagnostic codes or procedure codes for three outcomes: inflammatory conditions of the jaws, including osteonecrosis; major jaw surgery necessitated by necrotic or inflammatory indications; and jaw surgeries necessitated by a malignant process. The authors calculated stratified odds ratios and 95 percent confidence intervals. RESULTS: The results indicate that oral administration of BPs decreases the risk of adverse bone outcomes. In contrast, IV administration strongly and significantly increases the risk (P < .05) of adverse jaw outcomes or surgery. Across both osteoporosis and cancer, patients receiving IV BPs had a fourfold increased risk of having inflammatory jaw conditions and a greater than sixfold increased risk of having undergone major surgical resection in the jaw. CONCLUSIONS: Mode of bisphosphonate use results in different risk profiles for adverse jaw outcomes. While the authors documented an increased risk of inflammatory conditions and surgical procedures of the jaw for users of IV BPs, they did not find these observed increases for users of oral BPs. CLINICAL IMPLICATIONS: Physicians and dentists must be aware of the higher frequency of adverse jaw effects in patients receiving IV BPs, especially osteonecrosis of the jaw. While the authors' results have internal consistency, more clinical studies are needed to replicate and clarify the observed associations over long follow-up periods. 相似文献
