Lymphocyte membrane-associated IgG subclass antibodies in human periodontal disease were studied to ascertain the relative presence of cytophilic IgG antibodies and the membrane Fc receptors which bind them. The experimental approach correlated the effect of incubating gingiva in tissue culture medium to remove cytophilic antibodies with the changes in the number of Fc receptors detectable after washing. The evidence indicated that the majority of lymphocytes in mild gingivitis lesions lacked cytophilic IgG antibodies as well as Fc recetors. In severe gingivitis, the number of IgG subclass bearing lymphocytes increased to about half of the total lymphoid population, while the percentage of Fc receptor bearing cells remained quite low (12.3 % +/- 3.2, S.E.). The majority of IgG subclass bearing lymphocytes had membrane IgG which serve as receptors for antigen; such cells are classically defined as bone marrow (B) derived lymphocytes and serve as the progenitor for plasma cells. Gingival specimens for patients with periodontitis were found to contain the highest percentage of Fc receptor bearing lymphocytes (38.3% +/- 12.6 S.E.) and cytophilic IgG antibodies. The findings indicate that the clinical stages of human periodontal disease are characterized by different populations of infiltrating lymphocytes.

A case of persistent periodontitis was cured by replacement of all silver amalgam restorations. The patient had a history of developing a rash and swelling whenever she used jewelry containing silver. A patch test to silver nitrate was strongly positive.

A 48-year-old female patient presented with advanced periodontitis but was unable to proceed with periodontal therapy. After ten years of absence, her periodontal status appeared unchanged, if not slightly improved, despite the total lack of any dental or periodontal care. Studies on the biologic behavior of periodontitis are severely lacking and would appear to be a logical area for future epidemiologic surveys.

A clinical and radiological study was performed to test the utility of Diaket in the conservative treatment of chronic periapical periodontitis. 86% of the treatments were successful with a follow-up of 12 months.

Extracts of corn and some nuts were found to ubiquitously stimulate both adult and newborn cord blood lymphocytes to transform and produce a factor chemotactic for monocytes. This indicates that corn and nuts contain a mitogen and are potential stimulators of the cellular immune response. The exposure of lymphocytes to this mitogen in vivo might trigger a destructive inflammatory reaction in the surrounding tissues. These findings, therefore, suggest that foods such as corn and nuts may be responsible for some periodontal abscesses and may be contributing factors to the development of intrabony alveolar lesions and chronic periodontitis.

The authors determined the activity of the unspecific acid phosphatase in dental papillae excised from healthy subjects and individuals afflicted with periodontitis before and after the action of Elmex fluid. Clinically and histologically, the authors observed a regression of the inflammation. The possible causes are discussed. The total activity of acid phosphatase in the interdental papilla showed no significant changes, but the various tissue layers behaved differently. No permanent lesion will result from the wetting of the papillary and marginal gingiva which occurs during topical application of Elmex fluid to the surfaces of teeth.

Of the 25,672 patients who visited this clinic between January 1964 and March 1973, 126 were diabetic. These were examined statistically and the following results were obtained. 1. Together with diabetes the following disorders pertaining to the realm of oral surgery were observed: Alveolar pyorrhea (49 cases), infection of oral tissues other than periodontal tissues (24 cases), simple periodontitis (15 cases), tumors (13 cases), dental caries (9 cases), neuralgia (6 cases) and several disorders. 2. Of these 126 cases, 85 needed tooth extraction, which was actually performed in 67 cases with the following results: (a) Of the 67 cases, 13 developed complications such as dry socket, postoperative infection, sequestrum around the extraction socket, etc. This was a significantly higher incidence than in an equal number of controls. (b) In the cases with complications convalescence was prolonged to an average of 54.2 days. (c) In the cases with complications, the preoperative fasting blood sugar level averaged 194.5 mg/dl, which was much higher than in the cases which did not develop complications (average 142.4 mg/dl).

Eight patients under routine care for periodontitis received oral treatment with a form of coenzyme Q (7 / CoQ10 and 1 / hexahydrocoenzyme Q4). An unchanged plaque score showed the patients cooperated and were under plaque control. The periodontal score decreased (p less than 0.01) on CoQ treatment. Unexpectedly, the periodontal pocket depth decreased (P less than 0.05) on CoQ treatment since all patients were considered candidates for surgical intervention. Healing was so excellent 5-7 days post-biopsy that the biopsy sites were difficult to locate. The healing was viewed as extraordinarily effective. The mean value of the specific activities of the succinate dehydrogenase-coenzyme Q10 reductase of gingival biopsies increased (P less than 0.05) during treatment which could correlate with the extraordinarily healing. Treatment of periodontitis with coenzyme Q should be considered as adjunctive treatment with current dental practice.

The microflora around titanium implants and teeth in 4 beagle dogs was analyzed in order to follow the longitudinal development from healthy conditions to experimental gingivitis and periodontitis. A 2-month plaque control program was performed to establish healthy conditions on titanium implants and control teeth (baseline, day 0). Subgingival bacterial samples and radiographs were obtained. The plaque control was ceased and all measurements were repeated on day 21 (gingivitis). A new period of plaque control was initiated to re-establish healthy conditions (day 49). A cotton ligature was placed subgingivally around the implants and the control teeth to induce tissue breakdown. The ligatures were removed on day 91. The study was completed with registrations on day 121 (periodontitis). No significant microbiological difference was found between titanium implants and teeth in healthy conditions and in gingivitis and periodontitis. The mean total viable count increased 10 times on implants as well as on teeth. Streptococci were dominating at baseline: 40.2% on implants and 60.6% on teeth and decreased in gingivitis to 11.7% and 5.4%. When periodontitis had developed, the proportion of streptococci was < 1%. At baseline few Porphyromonas gingivalis and Prevotella intermedia were detected. They increased at gingivitis to 37.4% and 21.0%; when periodontitis developed, they comprised about 25.0%. Microbial colonization and establishment on titanium implants with healthy gingiva, experimental gingivitis and periodontitis follow the same pattern as on teeth.

The sample in the present study comprised 36 patients who were referred for treatment of periodontal disease. Twenty-four of them were early onset periodontitis (EOP) patients and 12 were adult periodontitis (AP) patients. Based upon the age, number of involved teeth and the location of diseased sites, the EOP patients were divided into two groups as juvenile periodontitis (JP) and rapidly progressive periodontitis (RPP). All the patients were individually examined both clinically and radiographically. At a baseline examination and 3 months after active therapy, the patients were evaluated for plaque, gingivitis, probing depths and probing attachment levels. Following instruction in proper oral hygiene measures, all of the patients were subjected to periodontal treatment. Treatment comprised scaling and root-planing, occlusal adjustment, tetracycline administration and periodontal surgery with osteoplasty. Results showed that age limits between JP and RPP cannot be drawn with certainty. The mean age for the JP group was 21.83 years and was 30.58 years for the RPP group. The number of involved teeth was found to increase with age. The first molars were the most frequently affected teeth followed by the incisors. Three months after active treatment, the response of periodontal tissues to therapy both in EOP and AP groups was almost identical.
