摘要:

Abstract.The review presented here covers metastatic local and systemic disease secondary to the accumulation of plaque or the formation of other pathogenic microbial depots in the mouth. At least 3 pathways may link oral infection to secondary disease, to wit metastatic infection due to transient bacteremia, metastatic immunological injury, and metastatic toxic injury. The available evidence is presented and examples are provided. They concern among others such divergent diseases as acute bacterial myocarditis, infective endocarditis, brain abscess, uveitis and iridocyclitis, trigeminal and atypical facial neuralgia, unilateral facial paralysis, fever of ‘unknown’ origin, and neutrophil dysfunct

摘要:

Abstract.In the present investigation wound healing was studied clinically in 8 younger (mean age 33.5 years) and 8 older patients (mean age 48 years), who were surgically treated for the same amount of severe periodontitis. This implies that the patients in the younger age group represented individuals with a higher degree of susceptibility to periodontal disease than the patients in the older age group. After surgery all patients were subjected to a carefully controlled oral hygiene program. Patients were recalled weekly until 8 weeks post surgery and again after 15 weeks for a final examination. At every recall session oral hygiene measurements were carried out and the bleeding tendency of the pockets was determined after probing with a standardized pressure. Bleeding on the basis of mechanical trauma after probing was considered to be a clinical parameter for wound healing in a plaque free environment.Results indicate that the oral hygiene program resulted in equally low plaque scores in both age groups. However, in a period from 5–15 weeks after surgery younger patients showed significantly more bleeding pockets than older patients. Furthermore it was found in both groups that the more loss of attachment there was, the slower the rate of wound healing.It was concluded that the time span for wound healing is longer in patients who are more susceptible to periodontal disease, than in those who are less susceptibl

摘要:

Abstract.In contrast to the generally held concept that periodontal disease is caused by microorganisms, Henriksson (1968) suggested that a nutritional deficiency of calcium might be the cause. He elicited secondary hyperparathyroidism in beagles from a low calcium/high phosphorus diet and found that the osteolytic demineralization of bone that followed seemed to involve alveolar bone more than other bones. In a report on 10 persons with advanced periodontal disease, Krook et al. (1972) stated that the disease was reversed when they were given 1 g Ca/day for 180 days. These results have been disputed.The present study is an attempt to repeat the experiment performed by Krooket al. (1972) under more stringent conditions. The hypothesis that calcium supplementation reverses destructive periodontal disease is tested.66 persons referred to our clinic for periodontal problems were prescribed at random calcium (1 g) or placebo tablets daily during a trial period of 180 days. Their periodontal status was examined at day 0 and at day 180. The parameters used for comparison were Plaque Index, Gingival Index, probing depth, mobility and furcation involvement. The radiographically registered level of alveolar bone was also recorded, but subsequently discarded since no change could be ascertained. The patients were interviewed as to their consumption of calcium via milk and cheese at days 90 and 180. This was in order to estimate roughly whether or not their dietary calcium consumption was adequate. The recommended allowance of 800 mg/day was used as a reference.During the trial period 7 persons withdrew – 2 from the test group and 5 from the control group. This was due mainly to digestive disorders, reported by the patients.A comparison at day 0 between the 31 test and 28 control patients revealed no statistical differences concerning the periodontal parameters studied. At day 180 both groups showed a slight improvement in Plaque Index, Gingival Index and probing depth; however, there was still no statistical difference between them. The dietary analysis established a low calcium consumption among 1/3 of the patients. Even in these cases calcium supplementation had no effect.It is concluded that calcium supplementation for 180 days does not influence the periodontal status of patients with moderate to advanced periodontal disease. Secondly, patients on a low calcium diet do not differ from those receiving an adequate supply. Finally, the study cannot support the hypothesis that calcium deficiency is a main cause of destructive periodontal diseas

摘要:

Abstract.In a cross‐sectional, epidemiological study of phenytoin induced gingival overgrowth in 77 institutionalized persons with epilepsy, the severity of the gum lesions was quantified by means of a precise new technique. Lesion severity was then compared statistically to other clinical and laboratory parameters. Positive correlations were detected between overgrowth severity and gingival inflammation, probing depths, calculus accumulation, plaque score and the measurement gingival margin to mucogingival junction (GM‐MGJ). No correlation was observed between lesion severity and patient age, daily drug dosage, plasma or saliva phenytoin level, or salivary concentration of the major phenytoin metabol

摘要:

Abstract.This clinical trial was primarily designed to determine to what extent the stiffness of toothbrush bristles and the abrasiveness of dentifrices influence the degree of gingival erosion. Further, the plaque removing effectiveness of the toothbrushes and dentifrices tested was evaluated. 24 dental hygienist students with clinically healthy gingivae volunteered for the study. A “soft” toothbrush with a bristle thickness of 0.15 mm, a “hard” toothbrush with a bristle thickness of 0.23 mm and 2 dentifrices of different abrasiveness were used for the experiment. The 2 brushes were also used without a dentifrice. Prior to each examination the teeth of the test subjects were brushed by the same dental hygienist. Evident signs of laceration or ulceration at any 1 of 4 gingival aspects of each tooth were recorded as brushing injuries. The teeth were then stained with basic fuchsin and the amount of remaining plaque was assessed according to the PLQ Index (Bay&Ainamo 1974).The use of the hard brush resulted in lower plaque scores and, at the same lime, more gingival erosions than the use of the soft brush. With both brushes a significantly greater number of lesions was recorded after use of an abrasive powder than when no dentifrice was employed. The difference in the amount of erosions occurring when utilizing either brush, without a dentifrice or with a moderately abrasive toothpaste, was not, however, found to be statistically significant. When assessed separately for the 2 brushes, the slight tendency towards lower PLQ scores with increasing abrasiveness of the dentifrice was not considered statistically significant. The study showed that the modest decrease observed in mean PLQ scores with increasing stiffness of the toothbrush bristles and with increasing abrasiveness of the dentifrice is accompanied by increased damage caused to the soft gingival

摘要:

Abstract.The aim of the present study was to determine the motivational effect of using a periodontal self‐examination manual prior to a self‐instructional manual in oral hygiene and to examine whether instruction provided at a later time than the scaling procedure improves the effect of the instruction. 74 patients with periodontal disease were divided into 3 groups: (1) A group of 23 patients who performed a self examination of their periodontal condition prior to self‐instruction in oral hygiene; (2) a control group of 27 patients who used only the self‐instructional oral hygiene manual; and (3) a group of 24 patients who were not given the self‐instructional oral hygiene manual before 6 weeks after the baseline examination. All these patients had their teeth scaled at the start of the study and after 3 and 7 months. The effect of the various modes of instruction was evaluated by assessments of plaque and gingival bleeding scores. These parameters were determined at the baseline and after 2 and 6 weeks and 3 and 7 months. The results demonstrated a significant improvement in plaque and gingival bleeding scores following the use of the self‐instructional manual in oral hygiene. The use of the periodontal self‐examination manual or a delay of the instruction had no additional effect on oral cleanliness. The level of oral hygiene and gingival health achieved at 3 months was maintained in all 3 groups for an additional period of 4 months. After that time, they were divided into 2 other groups depending on whether or not their plaque score was less than 20%. A total of 26 in the group who had a plaque score higher than 20% demonstrated a plaque score of less than 20% after having performed the tooth brushing test. 10 of the remaining patients, who still had a plaque score of more than 20% after the tooth brushing test, received additional instruction in oral hygiene which subsequently resulted in improved oral cleanliness a

摘要:

Abstract.A case of junvenile periodontitis treated by autogenous bone grafting is reported. The patient, an 18‐year‐old female, presented with periodontal lesions around the incisors and the first lower left molar. The first molar was severely affected with bone defects at the mesial aspect and in the furcation region and, for this reason, was selected for grafting. Minced fragments of bone with its marrow, obtained from the patient's iliac crest, were implanted into the diseased periodontium. 1 year after treatment, clinical and radiological inspection revealed the presence of boned. This bone completely filled the furcation area of the tooth but only partially the mesial aspect. There was, also, significant bone fill in the supracrestal reg
