OBJECTIVE Predicting the progression of periodontitis would allow for targeted supportive periodontal therapy. The purpose of this study was to determine the usefulness of salivary biomarkers for predicting the progression of periodontitis. DESIGN Eighty-five chronic periodontitis patients were enrolled in an 18-month longitudinal study. Amongst them, 57(More)
This study was conducted in order to identify the literature on oral health status and health-related QOL, review the findings systematically, and assess the association between them. We performed a literature search of reports published between January 1973 and June 2004, using five databases including MEDLINE. Only studies that used validated generic(More)
PURPOSE The purpose of the present study was to determine whether panoramic radiographs could predict physical contact between the mandibular third molar and the mandibular canal on limited cone-beam computed tomography, known as dental 3D-CT (3-dimensional computed tomography [3D-CT]). PATIENTS AND METHODS The association of images between the panoramic(More)
The purpose of this study was to determine the usefulness of salivary biochemical markers for the screening of periodontal disease and examine the agreement between the results of saliva enzyme tests and those of probing depth. The present study included a total of 187 subjects who underwent annual medical check-ups at the Comprehensive Health Care Center,(More)
This study aimed to determine whether the long-term use of a fluoride mouthrinse affects the salivary levels of mutans streptococci. Two hundred and fifteen schoolchildren (aged 9-10 years) participated. One hundred and forty-nine of these children had used a fluoride mouthrinse since 5 years of age at nursery school, and the remaining 66 children had not.(More)
Streptococcus sobrinus has four gtf genes, gtfI, gtfS, gtfT, and gtfU, on the chromosome. These genes correspond respectively to the enzymes GTF-I, GTF-S1, GTF-S2, and GTF-S3. An Escherichia coli MD66 clone that contained the S. sobrinus gtfU gene was characterized. Immunological properties showed that the protein produced by the E. coli MD66 clone was(More)
INTRODUCTION The objectives of this study were to clarify the characteristics of cranial-base morphology in adults with skeletal Class III malocclusion and investigate factors relating to the establishment of a skeletal Class III malocclusion. METHODS Initial lateral cephalograms of women were examined. Subjects with an ANB angle of 0° to 4°, normal(More)
BACKGROUND Periodontal screening plays an important role in the prevention of periodontal disease and promotes an improvement in oral health-related quality of life. The World Health Organization's Community Periodontal Index should be carried out by well-trained dentists. However, the Community Periodontal Index is an invasive technique, and if used for(More)
The aim of this study was to observe the time-lapse changes in the rat periodontal ligament (PDL) during function and tooth movement. Under Nembutal anaesthesia, time-lapse changes in the thickness of the PDL of the first molars were investigated in five 12-week-old adolescent rats with microcomputed tomography. Three-dimensional (3D) images were(More)
Among the various kinds of fibroblasts existing in the human body, the periodontal ligament (PDL) fibroblasts have been suggested as multipotent cells. Periodontal ligament fibroblasts are characterized by rapid turnover, a high remodeling capacity and remarkable capacity for renewal and repair. They also differentiate into osteoblasts and cementoblasts. We(More)
