Seven patients with chronic moderate to severe generalized periodontitis requiring periodontal flap surgery were selected for study. Internally beveled full thickness, apically positioned flaps with osseous recontouring were performed in 20 quadrants. Half the quadrants received a noneugenol dressing, and the other half were left undressed. Fluid Index, Gingival Index, inflammatory index, pocket depth and patient comfort were studied up to 16 weeks postoperatively. Results showed no difference in these parameters between quadrants where periodontal dressings were or were not used following surgery. The patients reported more pain and discomfort and the pain and discomfort was more severe postoperatively when the dressing was used. The results of this study suggest that a surgical dressing serves no useful purpose when periodontal flap surgery is performed.

The purpose of this study was to investigate the correlation between the composition of bacterial flora from infected root canals and clinical symptoms. The materials evaluated consisted of 28 teeth from 25 patients with apical periodontitis. Eubacterium were found to be significantly related to acute or chronic clinical symptoms and Peptococcus, Peptostreptococcus, and Porphyromonas gingivalis to subacute clinical symptoms. We suggested that Peptococcus, Peptostreptococcus, Eubacterium, Porphyromonas, and Bacteroides were significantly related to percussion pain; Porphyromonas and Bacteroides were significantly related to odor in the infected root canals. Many Bacteroides were isolated from most of the infected root canals.

Kinins are potent mediators of rheumatoid inflammation. The components of the kinin-forming system are hyperactive in RA. Excessive release of kinins in the synovial fluid can produce oedema, pain and loss of functions due to activation of B1 and B2 receptors. These receptors could be stimulated via injury, trauma, coagulation pathways (Hageman factor and thrombin) and immune complexes. The activated B1 and B2 receptors might cause release of other powerful non-cytokines and cytokines mediators of inflammation, for example, PGE2, PGI2, LTs, histamine, PAF, IL-1 and TNF derived mainly from polymorphonuclear leukocytes, macrophages, endothelial cells and synovial tissue. These mediators are capable of inducing bone and cartilage damage, hypertrophic synovitis, vessels proliferation, inflammatory cells migration, and possibly angiogenesis in pannus formation. These pathological changes, however, are not yet defined in human model of chronic inflammation (RA). Hence, the role of kinin and its interacting inflammatory mediators would soon start to clarify the detailed questions they revealed in clinical and experimental models of chronic inflammatory joint diseases. Several B1 and B2 receptor antagonists are being synthesized in an attempt to study the molecular functions of kinins in inflammatory processes (RA, periodontitis and osteomyelitis), and they represent and important area for continued research in rheumatology. Future development of specific, potent and stable B1 and B2 receptor antagonists or combined B1 and B2 antagonists with y-IFN might serve as pharmacological basis of more effective rationally-based therapies for RA. This may lead to significant advances in our knowledge of the mechanisms and therapeutics of rheumatic diseases.

There is scarce information on antibiotics prescription habits among dentists in general. The present investigation was undertaken to study some patterns of antibiotics prescription among Norwegian dentists. A total of 459 dentists (approximately 10% of Norwegian dentists) were randomly selected, and to each was mailed a letter describing the survey, accompanied by a questionnaire about age, type of practice, educational background and pattern of prescription of antibiotics. 78% of the dentists responded to these questions. The results indicate that during a typical week, 32% did not prescribe antibiotics, whereas 5% wrote greater than 5 prescriptions. The mean weekly number of prescriptions per dentist was 2.04. Periodontists and oral surgeons prescribed antibiotics significantly more often than did general practitioners and other disciplines. In addition, those with research and/or teaching experience seemed to prescribe significantly more often than those without. More than 1/3 of the sample indicated that they may prescribe antibiotics when treating periodontal diseases. Compared with other disciplines, periodontists prescribed such drugs significantly more often when treating periodontitis, but significantly less often in acute gingivitis, stomatitis and herpes simplex infections. Moreover, 22% of the dentists might prescribe antibiotics when the patient is in pain, 73 and 38% in cases of abscesses with or without generalized malaise, 2.5% in endodontic therapy, 60% to prevent general complications, and 68% for prophylactic use if the patient revealed a history of endocarditis. Norwegian dentists are somewhat restrictive in their prescription of antibiotics, but they mostly prescribe the correct drugs for the different conditions.

Presents the results of studies of the gingival thermal response in patients with chronic periodontitis exacerbations. Profezyme, an immobilized proteinase enzyme, was used in the treatment of 51 patients (test group) and chymotrypsin was administered to 43 controls. Anti-inflammatory action of profezyme was demonstrated. Reduction of the gingival temperature and pain alleviation evidence a high efficacy of the drug.

Good dental analgesia requires drugs that are endowed with strong and fast activity and that are well tolerated. In addition, optimal analgesia should essentially be of the peripheral type, thereby eliminating the risk of sedation that may cause unpleasant effects on the patient's daily life. Meclofenamic acid is among those substances whose analgesic effect is more evident than that of anti-inflammatory action. The mechanism of action of meclofenamic acid makes it distinctly different from other nonsteroidal anti-inflammatory drugs (NSAIDs) in that it inhibits the metabolic pathways of arachidonic acid and, at the same time, antagonizes the effects of prostaglandins at the peripheral receptor level. A number of controlled clinical trials showed that meclofenamic acid is an excellent analgesic, offering good tolerability when used in oral surgery, dysodontiasis, avulsion of the third impacted molar, and periodontitis. The following report is a presentation of results obtained in a controlled clinical trial in which the speed of pain relief was assessed in 20 patients suffering from acute periodontitis. The patients were treated orally with a single dose of meclofenamate sodium (100 mg) or with piroxicam-beta-cyclodextrin (20 mg). The intensity of the drug's analgesic effect was measured at 0.5, 1, 2, 4, and 6 h after administration. After initial testing, meclofenamate sodium was found to be significantly more effective than piroxicam-beta-cyclodextrin. Both the physician and patient found this drug to be considerably better. Pain relief after treatment with meclofenamate sodium was clinically and statistically faster than piroxicam-beta-cyclodextrin, and both drugs were found to be well tolerated.(ABSTRACT TRUNCATED AT 250 WORDS)

Periodontal disease can be divided into two categories: gingivitis (inflammation of the soft tissue) and periodontitis (destruction of the alveolar bone). Swelling, erythema, bleeding and gingival recession are common signs of gingivitis. However, most patients with gingivitis are asymptomatic. When patients complain of tooth pain and mobility, they already have severe periodontal disease. Dental loss secondary to periodontal disease may result in inadequate mastication, impaired phonetics and loss of self-esteem. Patients should be counseled that good oral hygiene and regular dental examinations can prevent periodontal disease.

A randomized study was carried out using 92 patients (39 taking a malarial chemoprophylactic agent and 53 not taking a chemoprophylactic agent) to investigate the rate of healing of ulcerative periodontitis after treatment. The chemoprophylaxis group who had been on 300 mg chloroquine weekly for at least one year and the non-chemoprophylaxis group who had not been on the regimen for at least one year were involved in the study which examined the global efficacy and assessment for pain relief over a period of 12 weeks after treatment for ulcerative periodontitis. A detailed, symtomatic and clinical assessment was made at biweekly intervals. Relief from pain was higher for the non-chemoprophylaxis group (94.2% vs. 46.2%, p less than 0.05). The global efficacy was statistically significant for the non-chemoprophylaxis group (87% vs. 38.4%, p less than 0.05). The outcome of treatment was not influenced by factors such as duration of chemoprophylaxis, initial severity of pain and smoking habits of the patients.

During a 3 weeks period, an immunotherapy by oral route was applied in patients presenting periodontal diseases (gingivitis and chronic adult periodontitis). This study, double blindly conducted, points out a statistically significative decrease of the main clinical symptoms of periodontal diseases (bleeding, erythema, oedema, pain, suppuration, fetidness) without any other local treatment and shows the interest of such a therapy in addition to the classical local treatments applied to patients presenting periodontal diseases.

The purpose of the study was to compare the flare-up rate for single-visit endodontics among teeth without radiographic or clinical signs of apical periodontitis, those with radiographic or clinical signs of apical periodontitis not previously root-treated, and those with apical periodontitis where retreatment was performed. All teeth were instrumented to a predetermined minimum size with a 0.5 per cent solution of sodium hypochlorite being used as the irrigant. The root canal was obturated without regard to the presence or absence of symptoms or diagnosis of the apical condition. The patients were given written post-operative instructions and a prescription for 600 mg ibuprofen to be taken if mild to moderate pain developed. If severe pain and/or swelling developed, the patient was instructed to telephone immediately and was considered to have had a flare-up. Teeth without signs of apical periodontitis did not have any flare-ups. One flare-up occurred in 69 teeth with signs of apical periodontitis not previously root-treated. The majority of the flare-ups (3 of 22 teeth) occurred in teeth with signs of apical periodontitis requiring retreatment.
