This article reports the endodontic and surgical management and 12-month follow-up of a maxillary lateral incisor diagnosed as type III dens invaginatus. A 21-year-old male patient presented to our clinics with complaints of pain and swelling in the right maxillary region. Intraoral and radiographical examination disclosed the presence of a peg-shaped maxillary right lateral incisor diagnosed as type III dens invaginatus. Root canal treatment combined with periapical surgery was initiated. After the completion of root canal treatment for both maxillary right central and lateral incisors, periapical surgery was scheduled. During the . . .surgery, periapical granulation tissue was curreted and bovine-derived hydroxil apatite (Unilab-Surgibone, Mississauga, Ontario, Canada) covered with collagen membrane (Unilab-Surgibone) was placed in the resorptive areas. ProRoot MTA (Dentsply, Tulsa, OK) was placed as a root end filling material. Postoperative 12-month follow-up revaled a satisfactory healing process. © 2008 Mosby, Inc.

The narrowing of an extraction site often becomes problematic when attempting to restore the space with a conventional wide-diameter implant. A woman is presented who was treated with a square head, mini-dental implant-supported fixed denture for a maxillary with a narrowed edentulous area, with a mesiodistal width of 5 mm. The implant, with a diameter of 2.4 mm, was inserted without reflecting the mucoperiosteal flap and was loaded immediately. During 12 months of follow-up, there has been no bone resorption and no inflammation observed around the implant. In conclusion, in terms of both clinical and aesthetic criteria, small diame . . .ter, mini-dental implants can be successfully used as an alternative to treatment with fixed partial dentures. © 2007 Mosby, Inc.

Objective: The objective of this study was to evaluate the repeatability of 2 nondestructive caries detection methods, ultrasound (ULS) and DIAGNOdent, for the detection of approximal caries lesions, and to evaluate 2 tips provided for the DIAGNOdent. Study design: White/brown-spot lesions (n = 42) were captured by a digital camera, and measured by test methods and confocal laser scanning microscope (CLSM). Intra- and inter-observer reliability, accuracy, and Cohen's kappa and Spearman's rho statistics were used. Results: At DIAGNOdent, intra-observer agreements were 78.5%, 66.7% for A tip and 59.5%, 47.6% for B for 2 examiners, res . . .pectively. Accuracy of both tips was 50% for the first examiner; 45.3% for A and 47.6% for the B tip for the second examiner. All ULS measurements were accurate, reliable, and positively and significantly correlated between examiners. Conclusion: The A tip of the DIAGNOdent was found to be better than the B tip for the detection of enamel caries. All DIAGNOdent and ULS measurements were positive and significantly correlated for both examiners. Both methods demonstrated high repeatability and accuracy. © 2008 Mosby, Inc.

The jawbones can be sites of various neoplastic conditions. Given the variety of processes affecting this particular anatomical area, formulation of a precise diagnosis can be challenging to clinicians. Limited jaw movement, pain, and facial asymmetry are common signs among patients, especially those with temporomandibular disorder (TMD). This paper reports a case of primary fibrosarcoma affecting the mandible and surrounding structures in a 14-year-old girl presenting signs and symptoms similar to TMD. Her condition was misdiagnosed, and she was treated for TMD over an extended period before the correct diagnosis was made for fibro . . .sarcoma. The patient underwent surgical resection with postsurgical radiotherapy and chemotherapy and now is being followed up. Although malignant lesions are rare in the temporomandibular joint (TMJ) region, dentists are advised to be aware of the condition and to keep in mind that patients who are admitting for TMD can also possibly be affected from neoplasms. Hence, those patients have to be examined meticulously to avoid misdiagnosis and mistreatment. © 2007 Mosby, Inc. All rights reserved Daha fazlası Daha az

Objective: Our hypothesis is that increased apoptosis in synovium might contribute to temporomandibular joint (TMJ) degeneration. To investigate this, we measured soluble Fas (sFas) and nuclear matrix protein (NMP) levels in TMJ synovial fluid from patients with disc displacement without reduction as indicators of apoptosis in the synovium. Patients and methods: Synovial fluid was obtained from 17 joints in 17 patients (11 female, 6 male; mean age, 31.5 ± 11.9 years; range, 19 to 55). Patients were referred to our clinic because of limited mouth opening, joint sounds, or TMJ pain. Synovial fluid obtained by arthrocentesis for therap . . .eutic reasons was analyzed by enzyme-linked immunosorbent assays for APO-1/Fas and cell death detection (NMP). Results: We studied 12 left (71%) and 5 right (29%) joints with disc displacement without reduction. The chief complaint was pain on the affected side and limited mouth opening. Only 2 patients had a click in the affected joint, whereas 14 reported pain and 17 had the limited mouth opening. All patients experienced a significant (P < .01) increase in maximal mouth opening immediately after arthrocentesis. Mean sFas and NMP levels were 484.9 ± 466.7 pg/mL (range, 17 to 1501) and 29.2 ± 13.7 U/mL (range, 8 to 52.8) respectively. Conclusion: Considering reports that increased sFas blocks apoptosis by inhibiting binding of FasL to Fas on the cell membrane, low level of sFas in our patients' synovial fluid (compared with amounts reported in joint inflammation or degeneration) suggests vulnerability to apoptosis in patients with internal derangement. © 2009 Mosby, Inc.

Objective: The aim was to investigate heat shock protein 60 (HSP60) expression in oral ulcerations of Behet's disease (BD). Study design: Biopsy specimens were obtained from patients with BD (n = 11), recurrent aphthous stomatitis (RAS) (n = 11), oral lichen planus (OLP) (n = 11) and healthy individuals (HI) (n = 11). Eight samples in BD and RAS groups were evaluable. All groups were analyzed by biotin streptavidin-aminoethylcarbazole using monoclonal mouse antibodies to HSP60 Ab-1 (clone LK1). Results: Immunostaining indicative of HSP60 expression in BD and RAS were significantly higher than HI. No significant difference was found . . .between BD and OLP except in the suprabasal layer of epithelium. Conclusions: Altered expression of HSP60 was found in ulcerative lesions of BD and RAS suggesting that HSP60 has an association with the etiology or chronicity of these inflammatory lesions. © 2010 Mosby, Inc Daha fazlası Daha az

Objective. This study was undertaken to investigate the influence of alendronate on bone formation after autogenous free bone grafting in rats. Study design. Fifty-six male Wistar-Albino rats were divided into 3 groups: baseline, saline-treated, and alendronate-treated groups, and followed up at 2, 4, and 12 weeks. In the femur of the rats, autogenous free bone grafts 3 mm in diameter and 2 mm in length were harvested with a standard trephine bur. The bone defects 3 mm in diameter and 2 mm in length were created 5 mm from the donor sites. Each graft was placed in the bone defect and stabilized by perifemoral wiring. The alendronate- . . .treated rats were administered 0.25 mg/kg alendronate subcutaneously daily. The saline-treated rats were given daily saline solution. Serum calcium, phosphate, parathyroid hormone, 1,25-dihydroxyvitamin D, bone alkaline phosphatase (BAP), osteocalcin, and urine calcium were measured. The changes in the number of osteoblasts bordering active bone formation surface and osteoid and lamellar bone formation were evaluated to measure anabolic bone activity. Results. Alendronate caused significant increase in serum osteocalcin and BAP levels biochemically and the number of osteoblasts histopathologically. Conclusion. Alendronate may be considered among therapeutic options to improve bone formation process in different bone remodeling cases. Further detailed studies should be focused on dosage- and time-dependent effects of alendronate on bone formation Daha fazlası Daha az

Background: Osteochondritis dissecans is a process in which segment(s) of cartilage separate from an articular surface. It is most often reported in the larger joints of the body, including the knee, elbow, hip, wrist, and ankle. Involvement of the temporomandibular joint (TMJ) is exceedingly rare. Objectives: To describe a probable case of osteochondritis dissecans and discuss the differential diagnosis for this condition. Study design: In addition to clinical examination the patient was imaged using panoramic radiography, computed tomography and magnetic resonance imaging. Results: Panoramic radiography showed separation of 2 roun . . .ded fragments superior to the right mandibular condyle. These were more precisely located using 3-dimensional computerized tomographic reconstructions. Magnetic resonance imaging demonstrated the right condyle as having low signal intensity area on T1-weighted images and a heterogeneous signal on T2-weighted images, with low signal dominance. No abnormality was apparent in the left TMJ. Conclusions: The patient was treated nonsurgically with a splint, occlusal adjustment, physiotherapy, and nonsteroidal antiinflammatory medications. Maximum mouth opening has increased from 24 mm to 39 mm 6 months following initiation of treatment, and pain has subsided. © 2006 Mosby, Inc. All rights reserved Daha fazlası Daha az

Objective. To comparatively evaluate the amount of apically extruded debris when ProTaper, ProFile, and HERO Shaper were used for the instrumentation of root canals. Study design. Sixty human mandibular central incisor teeth were randomly assigned to 3 groups, 20 teeth in each. The teeth in the 3 groups were instrumented according to the manufacturers' instructions until the working length, with ProTaper, ProFile, and HERO Shaper rotary instruments respectively. The debris produced was collected in polyethylene tubes. The liquid inside the tubes was removed by lyophilization and the remaining debris was calculated for each group and . . . compared. Results. All instruments tested produced a measurable amount of debris. No statistically significant difference was observed between ProTaper and HERO Shaper in terms of debris extrusion (P > .05). Similarly, no statistically significant difference was observed between ProFile and HERO Shaper even though HERO Shaper extruded a relatively higher amount of debris (P > .05). On the other hand, ProTaper extruded significantly more amount of debris compared to ProFile (P < .001). Conclusions. ProTaper caused a significantly higher amount of debris extrusion compared to ProFile. No statistically significant difference was observed among the other groups tested. As the quantity of debris extrusion is not the only factor responsible for acute exacerbations, future studies can be planned that focus on the types of bacteria causing flare-ups and methods for their elimination. © 2006 Mosby, Inc.

Autogenous bone particles can be obtained with bone collectors during implant osteotomy; however, collected bone particles contain oral microorganisms that may cause infectious complications. The purpose of this review was to summarize the clinical studies that have evaluated the degree of this contamination and the effectiveness of different decontamination methods. Stringent aspiration protocol, preoperative oral chlorhexidine rinse, and antibiotic prophylaxis are important precautions to be implemented when collected bone particles are to be implanted. Despite reducing contamination of collected bone particles, none of the method . . .s described in the literature can completely decontaminate collected bone particles or prevent the risk of infectious complications. Further research is needed to identify more effective decontamination methods. © 2008 Mosby, Inc. All rights reserved Daha fazlası Daha az
