Necrotizing ulcerative gingivitis (NUG) is a microbial disease of the gingiva in the context of an impaired host response. This form of gingivitis is relatively rare. NUG is an infection characterized by gingival necrosis presenting as"punched-out"papillae, spontaneous bleeding, pain, oral malodor, and pseudomembrane formation. The primary predisposing factors are bacterial plaque and an inadequate diet, but smoking and psychological stress may also affect the disease severity. NUG is associated with a characteristic bacterial flora, which includes fusiform bacteria, spirochetes, and Prevotella intermedia. Conventional treatment includes control of both the bacterial plaque and the secondary factors, as well as topical or systemic treatment biostimulative effect on wound healing, pain control, and inflammatory processes. Patients with NUG were treated using adjunct use of a diode laser (980 nm) for the control of pain and to accelerate the wound healing at day 2. 3. 5. 9, energy density was 9 J/cm. After treatment, the patients' quality of life improved faster than with conventional treatment. These results suggest that low-level laser therapy (LLLT) is an effective treatment for the reduction of pain levels and healing times. As a result, our case report shows that LLTT has a positive effect in relieving the symptoms of NUG.

OBJECTIVE:To study the effect of guava and synthetic vitamin C on the development of gingival inflammation during experimental gingivitis.

MATERIAL AND METHODS:Participants were randomly assigned to three groups supplemented daily with either 200g guava, 200mg synthetic vitamin C or water. The study included a 14 days pre-experimental period with oral hygiene instructions, scaling, prophylaxis and supplementation. Thereafter, experiment gingivitis was initiated, while continuing supplementation. At baseline, day 7 and day 14 of experimental gingivitis, Plaque Index (PlI) and Gingival Index (GI) were assessed. During the entire study, dietary fruit/vegetables intake was minimal.

RESULTS:PlI increased in guava-, vitamin C- and control group (ΔPlI: 1.30, 1.61 and 1.79 respectively). However, the guava group developed significantly less plaque compared to the control group. The GI increase of both guava- and vitamin C group was significantly less than the increase of the control group (ΔGI: 0.10, 0.24 and 0.87 respectively).

CONCLUSION:in a population of young non-smoking adults, consumption of either 200g guava/day or 200mg synthetic vitamin C/day, prior to and during the oral hygiene abstention period, has a preventive effect on the development of experimental gingivitis as compared to the control group that developed the usual amount of experimental gingivitis.

BACKGROUND: Oil pulling has been used extensively as a traditional Indian folk remedy for many years for strengthening teeth, gums, and the jaw and to prevent decay, oral malodor, bleeding gums, dryness of the throat, and cracked lips. AIMS: The aim of this study was to evaluate the effect of oil pulling with sesame oil on plaque-induced gingivitis and to compare its efficacy with chlorhexidine mouthwash. MATERIALS AND METHODS: A total of 20 age-matched adolescent boys with plaque-induced gingivitis were selected for this study. They were divided randomly into the study or oil pulling group (Group I) and the control or chlorhexidine group (Group II) with 10 subjects in each group. Plaque index and modified gingival index scores were recorded for the 20 subjects and baseline plaque samples were also collected. The plaque samples were used to identify the microorganisms and to measure the total colony count of the aerobic microorganisms present. The study group was subjected to oil pulling with sesame oil and the control group was given chlorhexidine mouthwash everyday in the morning before brushing. Reassessment of the index scores and collection of plaque for measuring the colony count of the aerobic microorganisms was done after 10 days. RESULTS: There was a statistically significant reduction of the pre- and post-values of the plaque and modified gingival index scores in both the study and control groups (P < 0.001 in both). There was a considerable reduction in the total colony count of aerobic microorganisms present in both the groups. CONCLUSION: The oil pulling therapy showed a reduction in the plaque index, modified gingival scores, and total colony count of aerobic microorganisms in the plaque of adolescents with plaque-induced gingivitis.

It has been suggested that vitamin C deficiency/scurvy is associated with gingival inflammatory changes; however, the disorder is very infrequently encountered in the modern era. Here, we report a case of extensive gingival overgrowth caused by vitamin C deficiency associated with metabolic syndrome and severe periodontal infection.

Naringin is a flavonoid that is commonly found in grapefruits. The objective of this study was to evaluate the effects of naringin on the growth of periodontal pathogens such as A. actinomycetemcomitans and P. gingivalis in vitro. For comparison, the effects of naringin on several oral microbes were also studied. Different concentrations of naringin solution were added to calibrated suspensions of A. actinomycetemcomitans and P. gingivalis. All the suspensions were incubated for 3, 6 and 24 h in an anaerobic chamber at 37 degrees C. At each time point, selected dilutions from each culture broth were plated on blood agar plates. Colonies recovered on blood agar were visually counted on days 3 and 5, respectively. A. actinomycetemcomitans showed a significant decrease (p < 0.05) in viable counts after 3 h when naringin was added at baseline. P. gingivalis also showed a marked growth reduction in the presence of naringin, and no colony forming units could be observed after 24 h. Naringin also had an inhibitory effect against all bacteria and yeasts tested. The results suggest that naringin possesses significant antimicrobial properties on periodontal pathogens in vitro. It also has an inhibitory effect on some common oral microorganisms in low concentrations.
