ジャーナル フリーUsing a questionnaire, 41 patients scheduled for orthognathic surgery were evaluated pre- and postoperatively to determine some of their psychological characteristics and treatment outcome from the patient's standpoint. Among other conclusions, the results showed that some patients may not fully understand the details of their deformity, despite a full explanation by the orthodontist and surgeon. Expectations regarding treatment outcome may be unrealistic even in patients with valid self-motivation for surgery. Social adjustment usually improves after treatment. Functional changes were noticed by over 80% of the patients and esthetic changes in over 90%.抄録全体を表示PDF形式でダウンロード (1045K) -

ジャーナル フリーA study was conducted to compare IgA levels in serum and saliva obtained from phenytoin-treated epileptic patients (PHT-TEPs) and a control group and to examine the correlation between IgA levels and clinical parameters. Eighteen epileptic patients treated with phenytoin and 18 periodontally healthy individuals with no systemic disease were included in the study. Clinical parameters were recorded, and samples of serum and saliva were obtained from each individual. IgA levels were determined by the radial immunodiffusion technique. Serum IgA levels were significantly lower in PHT-TEPs. No difference was found in salivary IgA levels between the PHT-TEP and control groups. Weak negative correlations were found between serum IgA level and gingival overgrowth index (GOI), and between salivary IgA level and GOI. None of the clinical parameters was significantly correlated with IgA level in the PHT-TEP group.抄録全体を表示PDF形式でダウンロード (657K) -

ジャーナル フリーDental technicians working in laboratories are exposed to different doses of various dusts. Disorders of pulmonary function may occur before radiogaraphic changes are evident. If these pulmonary function disorders are found at an early stage, the risk may be reduced by early, adequate local ventilation and by appropriate individual protective methods.
Unless adequate preventive measures are taken, pulmonary disorders will increase, finally leading to obstructive or restrictive ventilatory disorders, or progressive massive fibrosis. Results of pulmonary function tests provide objective criteria for prognosis, and are a measure of disease disability. In this situation, abnormal pulmonary function results should be considered as alarm signs.抄録全体を表示PDF形式でダウンロード (903K) -

ジャーナル フリーThrough the development of new techniques for bacterial growth and isolation, obligate anaerobes have been shown to be more prevalent than previously thought in the pathogenesis of periapical and pulpal diseases.
A follow-up study was conducted to examine the germicidal effect of 0.05% NaOCl, 10 mg/ ml metronidazole and supernatant of Ca (OH) 2 (0.025 ml) on four anaerobic microorganisms commonly found in root canals, and to compare the toxicity of these substances on cell cultures. In vitro testing revealed that 0.05% NaOCl and Ca (OH) 2 were both equally effective on these anaerobes. Also, metronidazole was found to be germicidally effective against Bacteroides melaninogenicus, Bacteroides oralis and Peptostreptococcus anaerobius, but ineffective against Veillonella alcalescens.
Furthermore, it was found that NaOCl and Ca (OH) 2 had a very destructive effect on cell cultures compared with their antimicrobial effect, whereas metronidazole was less toxic among the agents tested.抄録全体を表示PDF形式でダウンロード (687K) -

ジャーナル フリーForty-three uncooperative children ranging in age from 4-12 yr were pretreated with diazepam, acepromazine or a placebo, depending on their anxiety situations.
The results showed that diazepam has a significantly more powerful effect on the successful termination of the dental procedure and on encouraging the cooperation and compliance of patients than acepromazine or placebo. The placebo was also found to be effective for increasing the cooperation of patients with negative anxiety. No significant difference was established between the actions of premedicants on pain reaction and amnesia. In the light of the present findings, it is suggested that drugs with sedative and also anxiolytic effects will be more beneficial for increasing the cooperation of children with mild or high anxiety than drugs with a sedative effect alone.抄録全体を表示PDF形式でダウンロード (804K) -

ジャーナル フリーTrial production of a visible light-cured repair resin (powder/liquid type, TPL) as a denture base resin was carried out using cyclophosphazene monomer, and then the transverse and tensile strengths of the repaired specimens were examined. As a control, Triad Gel (TRI) was used. In the transverse strength test, TPL showed values of 507-470 kgf/cm2, which were about double those of TRI. As for tensile strength, TPL showed values of 329-268 kgf/cm2, and higher values were obtained in comparison with TRI, especially after 30 days of water immersion, when the values were doubled. The durability of TPL was favorable in comparison with TRI.抄録全体を表示PDF形式でダウンロード (586K) -

ジャーナル フリーA study was conducted to investigate the condylar path angle in relation to Angle's classification, amount of overbite and subjective symptoms. The condylar path angle in Angle's Class I group was similar to that in the Class II group. The angle in the Class III group was smaller than in the other two classes. A tendency for the angle to decrease as the amount of overbite became smaller was observed. The angle in the symptom group was slightly smaller than in the no-symptom group.抄録全体を表示PDF形式でダウンロード (685K) -

ジャーナル フリーCo-Cr alloy is used more frequently than Ni-Cr alloy as a non-precious alloy for cast plates in Japan. However, since the melting temperature of Co-Cr alloy is very high, about 1300°C, and since it oxidizes easily, a vacuum-pressure casting machine capable of melting this alloy in a reduced atmosphere has recently been developed. Using this machine, the effects of fusion temperature and the heating temperature of the cast ring on the Co-Cr alloy were studied.
It was found that in the vacuum-pressure casting method, both the fusion temperature of the Co-Cr alloy and the heating temperature of the cast ring had a significant effect (p<0.01) on the castability of the Co-Cr alloy.抄録全体を表示PDF形式でダウンロード (1527K) -

ジャーナル フリーTo examine whether the gingival epithelium provokes a loss of connective tissue attachment during periodontitis, periodontal ligament (PDL) cells and gingival fibroblasts (GF) were cultured with conditioned medium of gingival epithelial cells, and the collagenolytic activity of PDL cells and GF were examined, respectively. The epithelial cells were cultured in the presence or absence of lipopolysaccharide (LPS), and the respective conditioned media were added to the cultures of PDL cells and GF. The collagenolytic response of PDL cells to both of the conditioned media was 3- to 10-fold higher than that of each control, whereas the response of GF was only 1.4-fold higher. The LPS-stimulated epithelial conditioned medium showed a stimulation rate for collagenolytic activity similar to that of the LPS-free conditioned medium. These results suggest that human gingival epithelial cells, without LPS stimulation, secrete a substance which accelerates the collagenolytic enzyme activity of PDL cells for degradation of PDL fibers, in the absence of GF enzyme activity.抄録全体を表示PDF形式でダウンロード (1396K)
