RESUMO

Background. Conventional mechanical debridement alone cannot eliminate bacteria and their products from periodontal pockets. Adjunctive therapies improve tissue healing through detoxification and bactericidal effects. Photodynamic therapy (PDT) is a non-invasive treatment procedure that involves the use of a dye as a photosensitizer to attach to the target cell and be activated by a photon of an appropriate wavelength. This study aimed to assess the effectiveness of PDT in treating periodontitis as an adjunct to scaling and root planing. Methods. Fifteen subjects with chronic periodontitis were treated randomly with scaling and root planing (SRP), followed by a single PDT (test) or SRP (control) episode alone. Full-mouth plaque index (PI), sulcus bleeding index (SBI), probing depth (PD), and clinical attachment level (CAL) were assessed at baseline and 1-month and 3-month intervals. Microbiological evaluation of Porphyromonas gingivalis (Pg) in subgingival plaque samples was performed using a commercially available real-time polymerase chain reaction. Results. The results revealed a significant difference in PI, SBI, PD, CAL, and microbiological parameters between the groups one and three months after treatment. Conclusion. A combination of PDT and SRP gave rise to a significant improvement in clinical and microbiological parameters in patients with chronic periodontitis.

RESUMO

Background: Several hospitalized patients with complex medical issues depend on nursing staff for their daily health care due to several functional limitations. This study investigates the Oral Hygiene Care (OHC) activities and attitudes of nurses toward hospitalized patients. Materials and Methods: A cross-sectional survey was conducted at two private hospitals using a self-administered, structured questionnaire distributed to 585 nursing staff. Data were analyzed through percentages. Results: About 85.70% of the nurses ranked OHC as important; among them, 74.00% ranked as important to extremely important. Very few (2.40%) rated providing OHC to be an unpleasant task and the majority (41.80%) felt lack or proper training is one of the reasons for providing OHC satisfactorily. Conclusions: Nurses experienced significant behavioral and physical difficulties while providing OHC, but still found it important. Therefore, training programs are needed for nurses to improve OHC to hospitalized patients.

RESUMO

AIMS: The evaluation of clinical and specific microbiological changes associated with chlorhexidine chip in the chronic periodontitis patients. MATERIALS AND METHODS: A total of 30 chronic periodontitis patients (aged 20-65 years) having pocket depth of ≥5 mm in molar teeth were selected and randomly divided into following treatment groups: Group 1 - Scaling and root planning (SRP), Group 2 - SRP along with chlorhexidine chip and Group 3 - Only chlorhexidine chip. The clinical and microbial parameters were recorded at baseline and 1 and 3 months post-treatment as above. Benzoyl-DL-arginine-naphthylamide (BANA) chair side test was used for estimation of specific microbiota. RESULTS: Gingival index, probing pocket depth and clinical attachment level scores in selected teeth within the groups at different time intervals was significantly (P < 0.001) different. Although, the comparison between groups for specific microbiota in selected sites at different intervals was not statistically significant at baseline and 1 month, it reached statistical significance at 3(rd) month post-treatment. Although significant reductions in percentage of BANA positive sites were observed in all three groups, the Group 2 had significantly greater percentage of BANA negative sites. CONCLUSION: Local drug delivery using chlorhexidine chip enhances the benefit of SRP in the treatment of chronic periodontitis.

RESUMO

BACKGROUND: Serum leptin concentrations are reported to be elevated in patients with periodontal diseases and may have a modulating role in cardiovascular diseases. Serum leptin concentrations have not been assessed in periodontitis associated with acute myocardial infarction (AMI) to date. The purpose of this study was to assess the concentration of serum leptin in periodontitis associated with AMI. METHODS: A cross-sectional clinical study was conducted comprising a sample size of 120 participants divided into four groups (n = 30 each) based on their clinical signs: 1) control; 2) AMI; 3) generalized chronic periodontitis (GCP); and 4) GCP + AMI. Body mass index (BMI) was calculated and recorded for all the subjects based on BMI chart of the World Health Organization. After thorough clinical and oral examination, plaque index (PI), gingival index (GI), probing depth (PD), and clinical attachment loss (AL) were recorded. In addition, 2 mL venous blood was collected by venipuncture from all participants to determine serum leptin concentration using the enzyme-linked immunosorbent assay method. RESULTS: A strong correlation of serum leptin concentration to BMI was observed in AMI, GCP, and GCP + AMI groups. Serum leptin levels were significantly elevated in AMI, GCP, and GCP + AMI groups compared to the control group. Significant associations between serum leptin concentration and PI, GI, PD, and AL were also seen in the GCP group. PI, GI, PD, and AL were statistically significantly elevated in GCP + AMI and AMI groups. CONCLUSION: Elevated serum leptin concentration was associated with increased BMI, GCP, and AMI and may serve as a risk marker for these conditions.

RESUMO

BACKGROUND: The green tea extract is a naturally occurring product having beneficial effects that counteract with the pathobiological features of periodontitis and diabetes mellitus. Hence, the present study was aimed at incorporation of green tea extract into hydroxylpropyl methylcellulose and investigates its efficacy in chronic periodontitis patients associated with and without diabetes mellitus. MATERIALS AND METHODS: For the in vitro study, formulation of green tea strips and placebo strips, and analysis of drug release pattern from the green tea strips at different time intervals were performed. For the in vivo study, 50 patients (20-65 years), including 25 systemically healthy patients with chronic periodontitis (group 1) and 25 diabetic patients with chronic periodontitis (group 2) were enrolled. In each patient, test and control sites were identified for the placement of green tea and placebo strips, respectively. Gingival Index (GI), Probing Pocket Depth (PPD), and Clinical Attachment Level (CAL) were examined at baseline, first, second, third, and fourth weeks. Microbiological analysis for Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans was performed at baseline and fourth week. RESULTS: The in vitro study showed 10.67% green tea release at 30 min; thereafter, a slow release was noted till 120 min. IN VIVO STUDY: Both groups showed significant reduction in GI scores at the test sites. Group 1 showed significant (P < 0.001) PPD reduction at different time intervals at the test sites. However, group 2 showed significant reduction from baseline (5.30 ± 0.70) to fourth week (3.5 ± 0.97). Statistically significant gain in CAL at the test sites was observed both in group 1 (1.33 mm) and group 2 (1.43 mm). The prevalence of P. gingivalis in group 1 test sites was significantly reduced from baseline (75%) to fourth week (25%). CONCLUSIONS: Local drug delivery using green tea extract could be used as an adjunct in the treatment of chronic periodontitis in diabetic and non-diabetic individuals.

RESUMO

BACKGROUND: Clinical and epidemiological data suggest that negative life experience events, like depression, may contribute to an increased susceptibility to periodontal disease. AIM: To study the association between psychological stress and chronic periodontitis. MATERIALS AND METHODS: One hundred and eleven dentate individuals, of age 40 years and above, were selected. The clinical examination included, the number of teeth present, plaque index, Probing Pocket Depth, and Clinical Attachment Level. Assessment of Psychological stress levels were done by a questionnaire and were correlated with salivary cortisol levels, which were estimated biochemically by using the Enzyme-Linked Immunosorbent Assay (ELISA) method. RESULTS: Statistical analysis was done by using the student 't' test and Mann Whitney test. According to our observation, chronic periodontitis showed a significant correlation with hypercortisolemia (P<0.0001), work tension (P=0.04), economic problems (P<0.0001), clinical stress syndrome (P<0.0001), plaque index (P<0.0001), and unsecured job (P=0.003). CONCLUSION: Stress may be considered as an important risk factor for periodontal disease. Routine salivary cortisol assessment may be an economical and useful diagnostic marker to rule out stress in periodontitis patients.

RESUMO

BACKGROUND: The relationship between periodontal diseases in pregnancy and children born prematurely or with low birth weight has been increasingly investigated, showing positive and negative results, respectively. OBJECTIVE: To evaluate the association between Maternal Periodontitis and Preterm delivery or Low Birth Weight. MATERIALS AND METHODS: In this case-control study, 104 pregnant women without systemic disease or other risk factors for preterm labor were chosen. The control group (n = 52) had term labor (infants ≥37 weeks) and the case group (n = 52) had preterm labor (infants <37 weeks). Plaque index, bleeding index, and birth weight were measured. RESULTS: The data of plaque index (cases 1.21±0.56; controls 0.63±0.31), bleeding index (cases, 2.08±0.62; controls, 1.52±0.61), birth weight (cases, 2.01±0.36; controls 2.87±0.32), and Probing Pocket Depth (PPD) ≥4mm and Clinical Attachment Level (CAL) ≥3mm in at least 4 teeth (odds ratio 137.50, P value < 0.0001) revealed a statistically significant difference between the two groups P< 0.05). CONCLUSIONS: A noticeable relationship between periodontal health and duration of pregnancy; periodontal disease could be a risk factor for preterm labor. Oral hygiene maintenance should be a part of prenatal care protocol.

RESUMO

Tea, the commonly consumed beverage, is gaining increased attention in promoting overall health. In specific, green tea is considered a healthful beverage due to the biological activity of its polyphenols namely catechins. Among the polyphenols Epigallo catechin 3 gallate and Epicatechin 3 Gallate are the most predominant catechins. The antioxidant, antimicrobial, anticollagenase, antimutagenic, and c hemopreventive properties of these catechins proved to be helpful in the treatment of chronic diseases like periodontal disease. Studies have demonstrated that the type of processing mainly effects the concentration of catechins. Several epidemiological studies have proved that green tea also has some general health benefitting properties like antihypertensive, reduction of cardiovascular risk, antibacterial, antiviral, and antifungal activity. The present review concentrates on the effects of green tea in periodontal and general health.

RESUMO

BACKGROUND: Serum anti-cardiolipin (aCL) antibodies are prevalent in patients with periodontal diseases. These increased aCL concentrations were identified to play a modulating role in cardiovascular diseases. The present study aims to explore the effect of phase I periodontal therapy on immunoglobulin (Ig)M and IgG aCL antibodies in patients with acute myocardial infarction (AMI) associated with chronic periodontitis. METHODS: A cross-sectional randomized clinical study was conducted within two groups comprising a sample size of 72 patients (n = 36 each). Group 1 had clinical features of AMI, and group 2 had clinical features of AMI associated with chronic periodontitis. After a thorough clinical and oral examination, the plaque index (PI), gingival index (GI), probing depth (PD), and clinical attachment loss (AL) were recorded. Serum sample collection by venipuncture was done for estimation of serum IgM and IgG aCL concentration by using an enzyme-linked immunosorbent assay method. In group 2, phase I periodontal therapy was performed, and clinical and biochemical parameters were reanalyzed after 1 month. RESULTS: In group 2, the mean PI, GI, PD, clinical AL, and serum IgM and IgG aCL antibody levels were significantly higher than in group 1 patients. In addition, study results showed significant alterations in concentrations of serum IgM (P = 0.008) and IgG (P <0.001) aCL along with periodontal parameters after phase I periodontal therapy. CONCLUSION: The phase I periodontal therapy altered levels of serum IgG and IgM aCL antibodies in patients with AMI associated with chronic periodontitis.

RESUMO

BACKGROUND: The health model which forms the basis is knowledge, attitude, temporary, and permanent behaviors. Currently, more emphasis has been directed towards the combined influence of lifestyle, education, levels and socioeconomic factors, instead of regular risk factors in dealing with chronic illnesses. The present study is conducted to correlate the periodontal health of people with reference to lifestyle, education level, and socioeconomic status. MATERIALS AND METHODS: A cross-sectional study was conducted in the Department of Periodontics, Narayana Dental College and Hospital, Nellore. A total of 1350 subjects were examined and 948 patients were randomly selected from out patient department. Information about their lifestyle, education level, and socioeconomic status were recorded using a questionnaire and correlated with the periodontal status. RESULTS: The statistical analysis showed significant decrease in periodontitis when income and education levels increased. Also the prevalence of periodontitis associated with a healthy lifestyle is significantly lower when compared to an unhealthy lifestyle. CONCLUSIONS: There is a strong association of lifestyle, education level, and socioeconomic status with periodontal health.

RESUMO

The concept of tubular occlusion as a method of dentine desensitisation is a logical conclusion from the hydrodynamic hypothesis put forth by Brannström. The aim of this study was therefore to investigate qualitatively by SEM whether a 3% potassium nitrate/0.2% sodium fluoride mouthwash occluded tubule orifices, and by x-ray microanalysis, to characterise the nature of the deposits if any, following application. Following the 'dentine disc model' methodology 1mm thick tooth sections from unerupted molars were obtained. These were treated with the test and control mouthwashes and subjected to scanning electron microscopy. If any deposits were seen, they were to be subjected to elemental analysis using the energy dispersive x-ray analyser. Examination of all the dentine disc surfaces, treated by water (control), active and control mouthwashes demonstrated that none of the treatments, at any of the time intervals, had any visible effect on the dentinal tubule orifices i.e. there was no dentinal tubular occlusion seen. The results suggest that potassium nitrate does not reduce dentinal hypersensitivity, at least by tubule occlusion. This could mean that there is a different mechanism of action, which could not be detected by this in vitro model.
