OBJECTIVE As part of the Multisite Research Diagnostic Criteria For Temporomandibular Disorders (RDC/TMD) Validation Project, comprehensive temporomandibular joint diagnostic criteria were developed for image analysis using panoramic radiography, magnetic resonance imaging (MRI), and computerized tomography (CT). STUDY DESIGN Interexaminer reliability was(More)
INTRODUCTION Dental pain originating from the maxillary sinuses can pose a diagnostic problem. Periapical lesion development eliciting inflammatory changes in the mucosal lining can cause the development of a sinusitis. The purpose of this study was to describe the radiographic characteristics of odontogenic maxillary sinusitis as seen on cone-beam computed(More)
OBJECTIVE To determine the prevalence of infraorbital ethmoid cells on panoramic radiographs. Infraorbital ethmoid (Haller's) cells are extensions of ethmoid air cells into the areas of the orbit and maxillary sinus and may be seen when present on panoramic radiographs. STUDY DESIGN In this retrospective study, 233 panoramic radiographs were examined for(More)
Kitchen cabinet main material, particleboard has shown some problems in quality during installation. The physical properties of the particleboard panel were tested for its moisture content, density and dimensional changes. In collaboration with Signature Kitchen Sdn. Bhd., twenty-eight (28) houses in Kuala Lumpur and Selangor were selected for the(More)
An in vitro mineralizing cell-implant system was developed to study osteoblast attachment, secretion of extracellular (ECM) matrix proteins and mineralization. Saos-2 cells were plated on Tivanium (Tiv, Ti-6A1-4V), Zimaloy (Zim, Co-Cr-Mo) and glass disks. The cells were cultured in alpha-MEM medium with 10% fetal bovine serum and 50 microg ml(-1) ascorbic(More)
Histatins are a family of salivary proteins with bactericidal and fungicidal activities that contribute to the innate defense of the oral cavity. Histatins are present in the serous granules of the parotid and submandibular glands. The important role of histatins in saliva, and the limited information on their cellular and subcellular distribution, prompted(More)
  The research diagnostic criteria for temporomandibular disorders (RDC/TMD) have been employed internationally since 1992 for the study of temporomandibular muscle and joint disorders (TMD). This diagnostic protocol incorporates a dual system for assessment of TMD for Axis I physical diagnoses as well as Axis II psychological status and pain-related(More)
The effects of a layer-by-layer assembled carbon nanotube composite (CNT-comp) on osteoblasts in vitro and bone tissue in vivo in rats were studied. The effects of CNT-comp on osteoblasts were compared against the effects by commercially pure titanium (cpTi) and tissue culture dishes. Cell proliferation on the CNT-comp and cpTi were similar. However, cell(More)
INTRODUCTION Knowledge of the inferior alveolar nerve (IAN) position is important in avoiding nerve damage during invasive dental procedures. Because the exact position of the nerve bundle can vary in patients, this study evaluated the distance from the apices of mandibular premolar and molar teeth to the superior border of the mandibular canal. METHODS(More)
INTRODUCTION Cone-beam computed tomography (CBCT) has become a routine imaging modality for many orthodontic clinics. However, questions remain about the amount of radiation patients are exposed to during the scans. This study determined the amounts of radiation potentially absorbed by a patient during orthodontic imaging with a CBCT machine with various(More)
