Oral Health Meet 2018: In vitro evaluation of the effects of Pelargonium sidoides dc. Root extract and proanthocyanidins on oral bacteria viability - Nijole Savickiene - Lithuania Lithuanian University of Health Sciences, Lithuania Nijole Savickiene Lithuania Lithuanian University of Health Sciences, Lithuania Abstract INTRODUCTION: Elevated proportions of some subgingival microbial species have been associated with destructive periodontal disease activity. Biologically active compounds of Pelargonium sidoides root extract (PSRE) or Proanthocyanidins (PACNs) from this extract modulate bacterial virulence and stimulate host immune responses. There is no local delivery system of sustained release formulations with PSRE or PACNs available, however, bioactive capacities of these substances suggest them as promising prolonged local periodontitis treatment candidates. The purpose of this study: to evaluate the antimicrobial effect of different concentrations of PSRE and PACNs obtained from PSRE, against Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans and Streptococcus salivarius. Specific objective: Identification of the effective dose of PSRE and PACNs obtained from PSRE against i) the anaerobic strain P. gingivalis, major cause of periodontitis; ii) the putative periodontal pathogen A. actinomycetemcomitans and iii) the oral commensal (S. salivarius). Methodology: Preparation of different concentrations solutions from PSRE and (PACNs). Solutions were added in direct contact with bacteria at different concentration (v/v from mother solution). Bacteria and growth conditions: 1x105 /ml Bacteria were seeded in the log exponential growth phase (by o.d. evaluation). Metabolic evaluation: After 48 hrs bacteria viability was evaluated by metabolic colorimetric assay (alamar blue). Results: PSRE extract was effective in reducing P. gingivalis viability in a significant manner in comparison with untreated controls at all the tested concentrations. PSRE showed a strong antimicrobial effect also against A. actinomycetemcomitans and S. salivarius as the viability was significantly decreased in comparison with the untreated controls at all the tested concentrations. A statistically significant reduction of P. gingivalis viability was observed starting from 5% of PACNs extract. Conclusions & Significance: the use of a 30% PSRE and 20% PACNs dosage are suggested. Periodontitis is an interminable incendiary procedure started by the plaque biofilm. This is for the most part connected with improvement of damaging periodontal infection, prompting pocket arrangement, bone misfortune, and in the long run tooth misfortune. Ebb and flow comprehension of inception and movement of periodontal malady depicts dental plaque to be the essential etiological factor. This biofilm is joined by the nearness of math, which is for all intents and purposes consistently secured with unmineralised plaque. Analytics is plaque that mineralizes to frame calcified stores. Despite the fact that gum disease can create without supragingival analytics, it isn't obvious how much the nearness of mineralized store improves gingival aggravation. In the previous 40 years, analytics has been dismissed by plaque, and the solidified criminal has come to be seen as a fossilized leftover of minor essentialness. With respect to essentialness of dental stores, Schroeder summarized "Beginning harm to the gingival edge is probably because of enzymatic impacts brought about by the microorganisms of the plaque. This procedure is improved by the development of supragingival dental math, which gives further maintenance and along these lines advances new plaque collections." Plaque-prompted wearisome exacerbation at long last achieves game plan of periodontal pockets in which sub gingival investigation is spared. The latter is an assistant wonder; it's definitely not a purpose behind pocket course of action anyway an affiliated sign. This subgingival dental investigation subsequently favors and advances the chronicity of the irritation, and thusly, contributes toward fueling it legitimately. It has moreover been accepted that examination is plaque retentive and may square trademark and mechanical oral neatness works out. It in like manner may go about as an archive for exasperating substances, for instance, endotoxins and bacterial antibodies. Around 20 percent of dental examination is made of normal grid, non mineralized dejections containing littler scope living creatures, and additional phone substance taking after that of the covering fragile plaque that are found inside the collection of supragingival math. It is understood that the earth inside a biofilm can support sensible bacterial systems through nuclear scattering of enhancements through channels and examination can be entered by substances, for instance, endotoxins inside 24 hours. MATERIALS AND METHODS In the wake of looking for an educated assent, an aggregate of 30 subjects matured from 35 to 55 years (Mean age - 45 ± 5 years) were remembered for the investigation. Supra and subgingival analytics were reaped from 30 subjects having clinical proof of constant provocative periodontal sickness and generous math stores as a piece of periodontal treatment (one example from every patient). Patients having history of any basic disease, who experienced antimicrobial treatment since the past a half year, oral prophylaxis for at any rate a half year going before gathering the models, pregnant, lactating women, patients with salivary organ illness, and xerostomia were stayed away from the assessment. Care was taken to obtain tremendous single pieces (2-5 mm) and to keep up the genuineness of the examination tests. Quickly upon procurement, the gathered math tests were confined into two social occasions Social affair A (15 models): Harvested tests were immediatelykept in sterile penicillin bulbs to keep them dry. Tests in this get-together were introduced to Ultraviolet light in an UV chamber (NOVOUltraviolet germicidal chamber, Sankyo Denki, Japan) at 250 to 260 nm recurrence for 30 minutes in order to kill all the microorganisms present outwardly of the investigation. This strategy was generally done as such as to take out contamination in light of the overlying plaque. The models were turned over mindfully at fixed stretches to give enough introduction to UV light to all the surfaces. Social affair B (15 models): Harvested sampleswere quickly situated in clean saline. Tests from the two get-togethers were immediately moved to the Department of Microbiology for gram recoloring, acridine orange recoloring, oxygen expending bacterial culture examination and besides to Department of Oral Pathology for dull field microscopy. Examination tests were then crushed aseptically between two sterile slides and were isolated into four proportional parts. Conclusion From the outcomes, apparently reasonable vigorous microscopic organisms might be available inside analytics explicitly inside interior channels and lacunae.
Objective: There is an increased interest in looking at gender differences in health and disease, including oral health. This study assessed the gender differences in oral health habits among first year undergraduate students. Method: A descriptive cross-sectional study of first year undergraduate students with data collated using an interviewer administered questionnaire which elicited information on socio demographic characteristics of the participants, mouth cleaning habits and examination of the oral cavity to determine the oral hygiene status of the respondents. All data were analyzed using IBM SPSS version 20.0. The statistics carried out were frequency counts, percentages, mean, standard deviation, independent sample t-test and Chi square test. Results: Two hundred first year students made up of 100 males and 100 females participated in this study. The association between frequency of tooth brushing and gender of respondents was not statistically significant. However, there was statistically significant association between time of brushing and gender of the respondents with a higher proportion of females brushing before breakfast and before bed and a higher proportion of males brushing before breakfast only The association between duration of brushing and gender of respondents was statistically significant, with an increase in proportion of females as the duration of brushing increased. Similarly, there was statistically significant association between oral hygiene status and gender of the respondents with more males having fair oral hygiene while more females had good oral hygiene. Conclusion: Gender differences do exist in oral hygiene practices among first year undergraduate students with female having better oral hygiene status than their male counterparts. This may be because the timing as well as duration of tooth brushing among females is significantly different from that of males.
Local sterilization and tissue Repair which generally termed as LSTR, brings a radicular change in the field of conservative dentistry. Efficacy against antibacterial environment and nonsurgical healing of peri apical lesions much better than calcium hydroxide. LSTR 3Mix-MP, Using an antibacterial drug combination, therapy is a novel caries, pulpal treatment of primary tooth and root canal treatment. LSTR 3Mix-MP aims to eliminate causative bacteria from lesions, and after sterilization, the host's natural tissue recovery process usually the lesions are repaired or resolved. LSTR 3Mix MP where TAP (triple antibiotics paste) suchas:- Metronidazole, Ciprofloxacin, Minocycline and Vehicle MP Macrogol/polyethylene glycol and propylene glycol used to prepare.TAP has great antibacterial efficacy particularly against enterococciwhich remains after successful root canal treatment, effective eradication of the causative microorganisms during root canaltreatment procedures. Residual infection in Root canal therapy has always been an area of interdermind or vague for a treating dentalsurgeon. Lesion sterilization and tissue repair (LSTR) therapy is a non-surgical
