OBJECTIVE: The objective of this study was to present a comprehensive model for the pathogenesis of bisphosphonate-associated osteonecrosis of the jaw (BON). STUDY DESIGN: Review of PubMed literature relevant to BON, bisphosphonates (BPs), and bone remodeling. RESULTS: Six case reports of spontaneous resolution of BON lesions following administration of teriparatide (Forteo; Eli Lilly and Co., Indianapolis, IN) were identified. These reports suggest that osteoanabolic therapies may hold promise in BON management...

The aim of this case report was to evaluate the clinical and radiographic measurements of mandibular first molar bone support after mandibular third and second molar extraction and immediate augmentation of the extraction site with a combined autogenous bone graft with Bio-Oss materials. A pyramidal full-thickness mucoperiosteal flap with 1 distal releasing incision was used for removal of impacted third and second molars. During the procedure, autogenous bone graft was collected with a bone trap and then combined with Bio-Oss materials...

Periorbital emphysema is a rare complication of dental treatment. To date, there is only 1 case of periorbital emphysema during dental treatment reported in the literature. Etiologies and guidelines for the prevention of this complication during dental treatment were outlined and a rare case was presented.

BACKGROUND: Osteochondroma at the level of the coronoid process is unusual, causing a slowly progressive facial asymmetry and limitation of mouth opening. Histologically, it is a bone tumor covered by a thin capsule of cartilage. We present a literature review of cases published to date and present a new case in which osteochondroma originating in the coronoid process was associated with the formation of a cyst at the body of the zygoma, necessitating the reconstruction of the body of the zygoma...

Patients with coronoid process hyperplasia of the mandibular area are rare. The treatment of this disease is to increase the patient's mouth opening by surgery. There are various, but controversial, methods to treat it. We present a modified (gap) coronoidotomy procedure in detail and compare it with other conventional methods to treat coronoid process hyperplasia.

Dentigerous cyst is the most common odontogenic cyst. It is characterized by a unilocular radiolucent lesion that encloses permanent tooth buds or, under certain circumstances, displaced tooth buds. Buccal bony expansion is the most common clinical feature. Several treatment modalities have been mentioned in the literature for management of dentigerous cysts. The purpose of this article was to report an extensive right mandibular dentigerous cyst on a 10-year-old boy. Marsupialization was chosen to preserve the permanent tooth bud and a denturelike obturator was then provided for space maintenance and masticatory function...

OBJECTIVES: The objectives of this study were to analyze outcomes with miniplates in orthognathic surgery and define risk factors resulting in plate removal. STUDY DESIGN: Clinical files of 570 orthognathic surgery patients operated between 2004 and 2009 were reviewed: 203 had a bimaxillary operation, 310 a lower jaw osteotomy, and 57 an upper jaw osteotomy. Age, sex, and jaw movement were analyzed. Reasons for hardware removal were recorded. RESULTS: Hardware was removed in 157 patients (27...

OBJECTIVES: The aims of this study were to investigate the impact of dentofacial deformities on quality of life in Chinese patients and to make a comparison between facial deformities that do and do not involve the occlusion. STUDY DESIGN: Consecutive patients with dentofacial deformities requiring surgical correction were divided into 2 groups. Group A represented those who had undergone presurgical orthodontic treatment, and group B represented patients with square faces or prominent zygoma...

OBJECTIVES: An increasing trend toward implantation in complex cases, as well as early loading, is beginning to emerge in dental implantology. Long-term stability of the inserted implants greatly depends on the osseointegration process. Although there are numerous current research efforts aimed at functionalizing implant surfaces, no single factor has proved to be beneficial for osseointegration. The aim of the present study was to investigate whether a combination coating of collagen I and different cytokines enhances osseointegration...

OBJECTIVE: Recently, a pain assessment scale called "full cup test" (FCT) has been suggested for pain evaluation. It is claimed to be easier to use for the patient, and it allows using parametric tests for statistical analyses. The aim of this study was to evaluate the validity of the FCT in third molar surgery. STUDY DESIGN: The FCT was compared with 2 well accepted pain scales. Forty-eight patients who had fully impacted lower third molars were included. All patients were asked to fill 3 pain scales--visual analog scale (VAS), verbal rating scale (VRS), and FCT--daily during the first postoperative week...

The tongue flap has been described in reconstructing palatal defects. Nevertheless, properly securing the flap to the palatal defect has continued to pose a challenge, especially because the flap becomes mobile with normal activities (i.e., speech and swallow). For this reason, alternative fixation schemes have been discussed in literature, but do not always solve the problem. In this article, we offer an alternative method for positioning and securing the tongue flap into the palatal defect. The authors of this article believe that advantages of this technique include an increase in flap security and immobility and a decrease in postoperative maxillomandibular fixation requirement...

OBJECTIVE: In this study, the hypothesis that hBD-3 is upregulated by LPS via epidermal growth factor receptor (EGFR) signaling pathways to enhance metastasis in oral squamous cell carcinoma (OSCC) was tested. STUDY DESIGN: hBD-3 expression in human tissue specimens was evaluated by RT-qPCR and immunohistochemical staining. The presence of hBD-3 peptide in the culture supernatants of each type of treated cells was evaluated by enzyme-linked immunosorbent assay. The chemotaxis response to LPS or hBD-3 protein of SCC-25 cells or siRNA-hBD-3 transfected cells were also measured by chemotaxis assay...

OBJECTIVE: We studied the association between presence of complications and hospitalization outcomes, including hospital charges, length of stay in hospital, and in-hospital mortality. METHODS: The Nationwide Inpatient Sample for 2008 was used. All hospital discharges with a primary diagnosis of oral and oropharyngeal cancers were selected. Presence of complications was determined by using ICD-9-CM codes. The association between the presence of complications and outcomes (hospital charges, length of stay, and in-hospital mortality) was examined by multivariable linear and multivariable logistic regression analyses...

OBJECTIVE: The objective of this study was to investigate the validity and reliability of a quality of life instrument in patients with oral dysesthesia. STUDY DESIGN: Forty-five individuals newly diagnosed with oral dysesthesia (37 women, 8 men) were enrolled in this study. Individuals were interviewed using the Visual Analogue Scale (VAS), and the Oral Health Impact Profile (OHIP-14). Construct validity and internal reliability were examined. RESULTS: Patient rating of pain experienced, using VAS, correlated with OHIP-14 scores (P < ...

OBJECTIVE: The aim of this study was to evaluate, with the use of magnetic resonance images, mandibular condyle and articular disc movement on occlusal splint application. STUDY DESIGN: Thirty-five subjects were classified into "Pain" and "No-pain" groups based on visual analog scale scoring of temporomandibular joint (TMJ) pain and were categorized as bilateral normal disc (ND), unilateral anterior disc displacement (ADD), or bilateral ADD position. t test and analysis of variance with multiple comparisons were used for statistical analyses...

OBJECTIVE: The aim of this study was to assess relationships between panoramic indexes, bone mineral density (BMD), and osteoporotic fractures in men >60 years old. STUDY DESIGN: Body height and weight, body mass index, lumbar spine and hip BMD, and the presence of osteoporotic fractures were determined in the 127 studied men. Dental panoramic radiographs (DPRs) were used for measuring mandibular cortical indexes. RESULTS: BMDs were lower in patients with thinning and resorption of mandibular cortex...

OBJECTIVE: The aim was to evaluate immunoexpression of matrix metalloproteinases (MMPs) 1, 2, 7, 9, and 26 in calcifying cystic odontogenic tumor (CCOT). STUDY DESIGN: Ten cases of CCOT were assessed by immunohistochemical expression of MMPs 1, 2, 7, 9, and 26 in the parenchyma and stroma. Metalloproteinase immunoexpressions and their distribution pattern were semiquantitatively scored. RESULTS: MMPs were expressed in the parenchyma and stroma in all cases of CCOT...
