Objective. The aim of this study was to evaluate the effectiveness of a radial firing tip of an Er,Cr:YSGG laser as an adjunct to a nonsurgical periodontal treatment.Methods. Twelve patients with chronic or aggressive periodontitis were treated by conventional periodontal treatment using ultrasonic devices and hand instruments and, additionally, in two quadrants with an Er,Cr:YSGG laser. A new radial firing tip (RFPT 14-5, Biolase) was used with 1.5 W, 30 Hz, 11% air, 20% water, and pulse duration 140 μs. Microbiological smears were taken before treatment, one day after lasing, and three and six months after lasing. Pocket depths of all periodontal sites were measured before and six months after treatment.Results. The total bacterial load ofPrevotella intermedia,Tannerella forsythia,Treponema denticola,Fusobacterium nucleatum,Porphyromonas gingivalis, andAggregatibacter actinomycetemcomitansinside the pocket was reduced significantly throughout the whole examination time. Greater pocket depth reductions were observed in all groups. There was a slight higher reduction of pocket depth in the lased group after six months.Conclusions. These results support the thesis that Er,Cr:YSGG laser supported periodontal treatment leads to a significant reduction of periopathogenes and thereby helps the maintenance of periodontal health.

INTRODUCTION: Patients seem to adhere better to short-term periodontal treatment schemes. Besides, time-reduced treatments are more cost-effective. However, the degree of benefits related to this type of treatment still requires additional investigations. AIM: The present short-term study evaluated clinical and microbiological outcomes, from baseline to 3-months, of chronic periodontitis subjects treated by the one-stage full-mouth disinfection protocol. MATERIAL AND METHOD: Sixteen chronic periodontitis subjects (mean-age 49.87 ± 8.22) who met inclusion/exclusion criteria were included. A calibrated examiner measured whole-mouth plaque and gingival indices, periodontal pocket depth and clinical attachment level at baseline and at 3-months. Subgingival samples were also collected from the 5 most diseased periodontal sites to determine total bacterial load and levels of P. gingivalis and S. oralis by real time qPCR. Periodontal treatment consisted of full-mouth manual debridement plus wide intraoral use of chlorhexidine in gel and solution. Additionally, after debridement, individuals rinsed 0.12% chlorhexidine at home twice a day for the following 2 months. Data monitored were compared by paired Student-t test (p<0.05). RESULT: Statistical analysis revealed that, in general, one-stage full-mouth disinfection treatment provided significant clinical and microbiological improvements at 3-months. Total bacterial load showed one of the most pronounced reductions from baseline to 3-months (p=0.0001). Also, subgingival levels P. gingivalis and S. oralis reduced overtime. CONCLUSION: After a short period of monitoring, chronic periodontitis subjects showed clinical and microbial improvements following one-stage full-mouth disinfection treatment.

This study examined the prevalence of highly and minimally leukotoxic Actinobacillus actinomycetemcomitans in patients with periodontal disease. Pooled subgingival plaque samples from 136 patients with some form of periodontal disease were examined. Subjects were between 14 and 76 years of age. Clinical examinations included periodontal pocket depth (PD), plaque index (PI) and bleeding index (BI). The obtained plaque samples were examined for the presence of highly or minimally leukotoxic A. actinomycetemcomitans strains by the polymerase chain reaction (PCR). Chi-square and logistic regression were performed to evaluate the results. Forty-seven subjects were diagnosed with gingivitis, 70 with chronic periodontitis and 19 with aggressive periodontitis. According to chi-square there was no significant correlation detected between PD (chi2 = 0.73), PI (chi2 = 0.35), BI (chi2 = 0.09) and the presence of the highly leukotoxic A. actinomycetemcomitans. The highly leukotoxic A. actinomycetemcomitans strains were correlated with subjects that were 28 years of age and younger (chi2 = 7.41). There was a significant correlation between highly leukotoxic A. actinomycetemcomitans and aggressive periodontitis (chi2 = 22.06). This study of a Brazilian cohort confirms the strong association between highly leukotoxic A. actinomycetemcomitans strains and the presence of aggressive periodontitis.

ABSTRACT Objective: Chronic periodontitis (CP) is a common inflammatory disease that causes destruction to the supporting tissues of the teeth. Many treatment modalities tried to stop the disease progression. Platelet-rich plasma (PRP) is one of the regenerative methods that used in adjunct to conventional periodontal treatment. The aim of this study was to evaluate the anti-inflammatory effect of PRP by monitoring the lymphocyte count before and after its application to the periodontal pocket. Materials and Methods: Twenty patients, with CP and a pocket depth equal to or deeper than 4 mm, subjected to scaling, root planing, and PRP injection into the pocket. The lymphocyte count measured before and after 1 month from PRP application. Clinical periodontal parameters were taken during two visits (1 month apart), with customized stent fabrication. Results: All clinical periodontal parameters showed a reduction in their value following 1 month of PRP application. . There was a noticeable reduction in lymphocyte count from (mean 2.47 ± 0.91) to (mean 1.94 ± 0.77). Conclusion: In addition to its traditional uses, PRP has a great role in the periodontal treatment by its anti-inflammatory effect.

This paper reports estimates of the periodontal status of US population derived from data from Phase 1 of the Third National Health and Nutrition Examination Survey conducted by the National Center for Health Statistics in collaboration with the National Institute of Dental Research from 1988 to 1991. A total of 7,447 dentate individuals 13 years of age and older, representing approximately 160.3 million civilian non-institutionalized Americans, received a periodontal assessment. Measurements of gingival bleeding, gingival recession level, periodontal pocket depth, and calculus were made by dental examiners. Assessments were made at the mesiobuccal and mid-buccal sites of all fully erupted permanent teeth present in two randomly selected quadrants, one maxillary and one mandibular. All data were weighted and standard errors calculated by special software to adjust for the effect of sample design. Although over 90% of persons 13 years of age or older had experienced some clinical loss of attachment (LA), only 15% exhibited more severe destruction (LA ≥ 5 mm). Prevalence of moderate and severe LA and gingival recession increased with age, while prevalence of pockets ≥ 4 mm or ≥ 6 mm did not. These data suggest that the increasing prevalence of LA with age is more associated with increasing prevalence of recession than with changes in the prevalence of pockets or age. The extent or number of affected sites with advanced conditions for loss of attachment, pocket depth, or recession was not large for any age group. Differences in prevalence of moderate and severe loss of attachment, moderate and deep pockets, and recession were found among gender and race-ethnicity groups. Females exhibited better periodontal health than males, and non-Hispanic whites exhibited better periodontal health than either non-Hispanic blacks or Mexican-Americans.

Stabilizing or reducing periodontal pocket depth can have a positive influence on the retention of teeth in dogs. A topical 2 % clindamycin hydrochloride gel (CHgel) was evaluated for the treatment of periodontal disease in dogs. The CHgel formulation provides for the sustained erosion of the matrix, but also flows into the periodontal pocket as a viscous liquid, and then rapidly forms a gel that has mucoadhesive properties and also may function as a physical barrier to the introduction of bacteria. A professional teeth cleaning procedure including scaling and root planing was done in dogs with one group receiving CHgel following treatment. Periodontal health was determined before and after the procedure including measurement of periodontal pocket depth, gingival index, gingival bleeding sites, and number of suppurating sites. There was a statistically significant decrease in periodontal pocket depth (19 %), gingival index (16 %), and the number of bleeding sites (64 %) at 90-days in dogs receiving CHgel. Additionally, the number of suppurating sites was lower (93 %) at 90-days for the group receiving CHgel. The addition of CHgel effectively controlled the bacterial burden (e.g., Fusobacterium nucleatum) at both day 14 and 90. Gingival cells in culture were shown to rapidly incorporate clindamycin and attain saturation in approximately 20-minutes. In summary, a professional teeth cleaning procedure including root planning and the addition of CHgel improves the gingival index and reduces periodontal pocket depth.

ABSTRACT The use of dental lasers for treatment of periodontal diseases has been the area of interest in the recent years. Current evidence indicates that the use of lasers for the treatment of adult chronic periodontitis—either used solely or as an adjunct to traditional scaling and root planning therapy—offers minimal benefit. This article which is a peer review of various articles provides a brief explanation of the mechanism behind soft tissue lasers. The use of laser therapy in addition to traditional nonsurgical periodontal treatment in the management of periodontal diseases is reviewed. Lasers have been applied for hard and soft tissue debridement, as also for the bacterial load reduction from the periodontal pocket. Although, subgingival application of few of them during nonsurgical periodontal therapy can result in undesired outcomes, even when using manufacturer-recommended parameters. Over the past 20 years the research conducted regarding the clinical application of lasers is very limited. This article tries to fill in the void by reviewing the current and potential application of laser therapy. It has in turn proven to be a promising field in nonsurgical periodontal treatment of diseases. How to cite this article Uttamani J, Shaikh I, Kulkarni V.

Periodontopathogenic Bacteria

This study investigated whether an improvement in periodontal health resulted in changes in the prevalence of periodontopathogenic bacteria in saliva and tongue coatings and a reduction in volatile sulfur compounds (VSCs: H2S and CH3SH) linked to oral malodour. The subjects were 35 patients who visited the breath odour clinic of Kyushu Dental College, Japan. Their mean age was 51.2±18.3 years (mean±sd). A clinical examination performed at baseline and 2 months after periodontal treatment assessed VSCs in mouth air using gas chromatography, periodontal probing depth and bleeding on probing (BOP) in all subjects; saliva and tongue coatings were also collected. Genomic DNA was isolated from the samples, and the proportions of five periodontopathogenic bacteria (Porphyromonas gingivalis, Tannerella forsythensis, Treponema denticola, Prevotella intermedia and Prevotella nigrescens) were investigated using quantitative real-time PCR. The subjects were classified into four groups based on the presence of a periodontal pocket of more than 4 mm (PD) and VSCs above the organoleptic threshold level (VSCT) as follows: –PD/–VSCT group, subjects without PD or VSCT; –PD/+VSCT group, those without PD but with VSCT; +PD/–VSCT group, those with PD but without VSCT; and +PD/+VSCT group, those with PD and VSCT. Although the mean PD values in the +PD/–VSCT and +PD/+VSCT groups, BOP in the +PD/+VSCT group, and H2S and CH3SH concentrations in the –PD/+VSCT and +PD/+VSCT groups were greater than in the other groups at baseline, we found no significant difference among the four groups after periodontal treatment. The proportion of periodontopathogenic bacteria in saliva was higher in the +PD/–VSCT and +PD/+VSCT groups than in the –PD/–VSCT and –PD/+VSCT groups at baseline and after treatment, but the proportions of bacteria in saliva after treatment were reduced compared to the baseline. Furthermore, the differences in the proportions of the five target bacteria in the tongue coating were not as apparent as those in saliva at baseline or after treatment. The prevalence of periodontopathogenic bacteria in saliva may reflect periodontal health status and influence VSC levels in mouth air.

(1) Background: The progression of periodontitis, induced by polymicrobial dysbiosis, can be modified by systemic or environmental factors such as stress or anxiety affecting host response. The purpose of this study is to evaluate the potential associations between psychosocial factors scores or salivary cortisol levels with clinical periodontal parameters and bacterial environment in patients with periodontitis; (2) Methods: Subgingival microbiota was collected in two pathological and one healthy sites from thirty diseased patients (before/after scaling and root planing (SRP)) and from one healthy site from thirty control patients. Usual clinical periodontal parameters were recorded, and a saliva sample was harvested. Patients completed stress and anxiety self-assessment questionnaires. Cortisol concentrations were determined by ELISA and bacteria were identified by PCR; (3) Results: No correlation between salivary cortisol and the stress-anxiety self-declared was found (p > 0.05), but high concentrations of this molecule were associated positively and linearly with periodontal pocket depth (p = 0.04). It appeared that certain psychosocial stressors are associated with a modulation of the bacterial colonization of pockets of diseased group (before/after SRP), notably concerning Tannerella forsythia (p = 0.02), Porphyromonas gingivalis (p = 0.03), Fusobacterium nucleatum (p = 0.049) and Campylobacter rectus (p = 0.01). (4) Conclusion: This study reveals associations between bacteria colonization and psychosocial parameters in periodontitis that needs to be further investigated.

Background. Pharmacological factors, such as ibuprofen, released topically in the periodontal pocket modulate the host response and enhance the influence of non-surgical periodontal treatment. Methods. In this double-blind, randomized, split-mouth, clinical trial, 38 outpatients with mild to moderate chronic periodontitis were enrolled by applying the simple random sampling method. They had at least one tooth with a periodontal pocket depth of >4 mm in each quadrant and had undergone phase I of periodontal treatment one week after scaling and root planing (SRP). The parameters of clinical periodontal evaluation, including probing pocket depth (PPD), clinical attachment level (CAL), plaque index (PI), and bleeding index (BI), were measured. In addition, two mandibular molar teeth in one quadrant were randomly nominated for subgingival irrigation with 0.5 mL of 2% ibuprofen or placebo mouthwash. The measurements were repeated after at least one week for three months. Results. Thirty-four individuals (18 women and 16 men), with an age range of 28‒36 years, were evaluated for three months. Moreover, periodontal clinical parameters were assessed within three months. There was a significant improvement in pocket depth (PD) and clinical attachment level (CAL) readings after 12 weeks in both groups (paired t-test). On comparing, the group with scaling and root planing (SRP) + ibuprofen showed more favorable results than the group with SRP + placebo (P<0.05). There were significant improvements in PI and BI in both groups; the differences between the two groups were significant (P<0.05). Conclusion. The mouthwashes containing ibuprofen might reduce the symptoms of periodontal disease and might be used as an adjunct in the healing process

Background. Evidence is limited on the effect of periodontal treatment on improving HbA1c levels in non-diabetic patients with chronic periodontitis. This study aimed to compare HbA1c levels in non-diabetic patients without periodontitis and nondiabetic patients with chronic periodontitis at baseline and to evaluate the effect of non-surgical periodontal treatment on glycemic control in non-diabetic chronic periodontitis patients. Methods. In this interventional study, 30 non-diabetics, aged 35‒65 years, were selected and divided into two groups (n=15). Group A consisted of non-diabetics without periodontitis, and group B consisted of non-diabetics with mild to moderate chronic periodontitis. For all the subjects, periodontal parameters, including plaque index, gingival index, periodontal pocket depth, and clinical attachment loss, and laboratory parameters of FBS and HbA1c were measured and recorded. Independentsamples t-test was used to compare periodontal and laboratory parameters between the two groups; paired-samples t-test was used for intra-group comparisons. Results. HbA1c level in group B (5.4±0.42%) was significantly higher than that in group A (5.04±0.43%) (P=0.03) at baseline. Three months after treatment, improvements were achieved in all the periodontal parameters in group B, with a significant decrease in HbA1c levels (P=0.006). Conclusion. Non-surgical periodontal treatment resulted in a significant decrease in HbA1c levels in non-diabetic patients with chronic periodontitis. Although these levels did not reach the level of non-diabetic patients without periodontitis, it could be concluded that an improvement in the periodontal condition might lead to near-normal glycemic levels.
