Resultados: Predominio del grupo 65-69 años y sexo femenino, persistencia de inflamación gingival en el 30,0 % del Grupo 1 al tercer mes, disminuyó la profundidad al sondaje y hubo ganancia de inserción clínica, mejorando sus medias en el tiempo. Se logró un 100,0 % de efectividad de curación en los Grupos 2 y 3. Conclusiones: Elevada efectividad de la aplicación tópica subgingival de tetraciclina y azitromicina con cemento quirúrgico, sobre aquellos tratados con raspado y alisado radicular convencional.

ABSTRACT Introduction: Antimicrobial therapy after scaling and root planing treatment in the elderly has not been evaluated at the "Mártires del Moncada" Provincial Teaching Stomatology Clinic in Santiago de Cuba. Objective: To evaluate the effectiveness of tetracycline and azithromycin in the treatment of scaling and root planing in the elderly. Method: Quasi-experimental study of therapeutic intervention, carried out between 2018 and 2019, on 30 patients with the age of 60 and over and diagnosed with chronic periodontitis. Three groups with 10 cases were created using the simple randomized method. Group 1 treated with the conventional technique and groups 2 and 3, after using the same technique, a subgingival concentration of tetracycline and azithromycin was applied respectively and surgical cement placement for 7 days. Variables such as age, sex, clinical picture, evolution of signs and symptoms at the seventh day, 1 and 3 months, and healing effectiveness were used. The statistical validation was through the Chi-square test, with a 95% reliability and the antimicrobial effectiveness, through the Analysis of Variance ANOVA. Results: Predominance of the group age between 65 and 69 years and female sex, persistent gingival inflammation in 30,0 % of group 1 at the third month, decreased the depth of the catheterization and there was a clinical insertion gain, improving their averages in time. A 100.0% healing effectiveness was achieved in groups 2 and 3. Conclusions: High effectiveness of subgingival topical application of tetracycline and azithromycin with surgical cement, over patients treated with conventional scaling and root planing.

Effect of periodontal treatment in patients with periodontitis and diabetes: systematic review and meta-analysis

Abstract The evidence is inconclusive regarding the effect of periodontal treatment on glycemic control and systemic inflammation in patients with type 2 diabetes (T2D) and periodontitis Objective: To evaluate the effect of scaling and root planing (SRP) on the metabolic control and systemic inflammation of patients with type 2 diabetes (T2D). Methodology: A literature search was conducted using the MEDLINE database via PubMed and the Cochrane Central Register of Controlled Trials, from their oldest records up to July 2018. Only randomized clinical trials (RCT) were considered eligible for evaluating the effect of periodontal treatment on markers of metabolic control [glycated hemoglobin (HbA1C)] and systemic inflammation [C-reactive protein (CRP)] in patients with T2D. The quality of the studies was evaluated using the Cochrane Collaboration risk assessment tool. Meta-analyses were performed for HbA1c and CRP using random effects models. The size of the overall intervention effect was estimated by calculating the weighted average of the differences in means (DM) between the groups in each study. Heterogeneity was assessed using the Q-statistic method (x2 and I²). The level of significance was established at p<0.05. Results: Nine RCT were included. SRP was effective in reducing HbA1c [DM=0.56 (0.36-0.75); p<0.01] and CRP [DM=1.89 (1.70-2.08); p<0.01]. No heterogeneity was detected (I2=0%, p>0.05). Conclusions: SRP has an impact on metabolic control and reduction of systemic inflammation of patients with T2D.

Plasma rich in growth factors (PRGF) in non-surgical periodontal therapy: a randomized clinical trial

Abstract The aim of this split mouth, double blinded, randomized clinical trial was to evaluate the clinical efficacy of use of Plasma rich in growth factors (PRGF) as an adjunct to scaling and root planing (SRP) in the treatment of periodontal pockets. Twenty six patients (15 males, 11 females) diagnosed with generalized periodontitis with Pocket Depth > 5mm and plaque index score < 1.5, were randomly allocated by using computer generated random sequence, into two groups, one treated with intra-pocket application of PRGF adjunct to SRP and other with SRP alone. The clinical outcomes like pocket depth (PD), relative attachment level (RAL) and sulcus bleeding index (SBI) were assessed at baseline, 3 months and 6 months. Twenty two patients (44 sites) were analyzed at the end of 6 month follow-up, using SPSS 20.0v software. There was a significant statistical difference observed between both the groups favouring SRP +PRGF group in terms of PD (p = 0.007) and RAL (p = 0.021) at the end of 6 month follow-up. Also there was a statistical significant difference (< 0.001) at all time points compared to baseline, for all parameters in intra-group comparison. Moreover, the sites with PD>4mm necessitating further treatment after 6-month follow-up were significantly lesser for SRP+PRGF group. The use of PRGF technology in non-surgical periodontal therapy, by single intra-pocket application in to periodontal pockets as an adjunct to SRP, in chronic periodontitis patients, was found to be effective in reduction of pocket depth and gain in clinical attachment level.

Alanina aminotransferasa salival como biomarcador de periodontitis en pacientes de la Clínica de Periodoncia de la Unidad Médico Didáctica / Salivary alanine aminotransferase as a biomarker of periodontitis in patients of the Periodontics Clinic of the Didactic Medical Unit

La alanina aminotransferasa (ALT) es una enzima citoplasmática, más específi ca de daño hepático, la cual ha sido cuantifi cada en líquido crevicular; sin embargo, son escasos los reportes que señalan que la saliva pueda ser una herramienta de utilidad para la medición de esta enzima. El objetivo del estudio es identifi car los niveles de la enzima ALT en saliva no estimulada de pacientes sanos y pacientes con periodontitis, antes y después del tratamiento periodontal no quirúrgico. Material y métodos: Se evaluaron 24 pacientes con periodontitis moderada a avanzada generalizada (n = 16) y pacientes con periodonto sano (n = 8) que acudieron a la Clínica de Periodoncia de la Unidad Médico Didáctica de la Universidad Autónoma de Aguascalientes, donde al grupo experimental se le realizó tratamiento periodontal no quirúrgico. Se recolectó saliva no estimulada antes y después del tratamiento periodontal para evaluar los niveles de ALT, procesando su lectura con un analizador semiautomático para química clínica. Resultados: En el grupo experimental se encontró una concentración de ALT de 52.47 ± 72.68, que disminuye a 14.95 ± 16.88 posterior a la terapia periodontal, a diferencia del grupo control con una media de 4.488 ± 3.229, se detectó una media de 5.638 ± 5.935 posterior al tratamiento periodontal. Conclusión: En los pacientes que fueron sometidos al tratamiento periodontal no quirúrgico, la concentración de ALT tiende a disminuir de manera notable; sin embargo, los resultados mostrados no fueron estadísticamente significativos (AU)

Alanine aminotransferase (ALT) is a cytoplasmic enzyme, more specific for liver damage, which has been quantifi ed in crevicular fl uid, however there are few reports that saliva can be a useful tool for the measurement of this enzyme. The objective of the study is to identify the levels of the ALT enzyme in unstimulated saliva of healthy patients and patients with periodontitis, before and after the non-surgical periodontal treatment. Material and methods: 24 patients with moderate to advanced generalized periodontitis (n = 16) and patients with healthy periodontium (n = 8) who attended the Periodontics Clinic of the Didactic Medical Unit of the Autonomous University of Aguascalientes where the experimental group underwent non-surgical periodontal treatment. Unstimulated saliva was collected before and after the periodontal treatment to evaluate the ALT levels, processing its reading with a semi-automatic analyzer for clinical chemistry. Results: In the experimental group, an ALT concentration of 52.47 ± 72.68 was found, decreasing to 14.95 ± 16.88 after periodontal therapy, unlike the control group with a mean of 4.488 ± 3.229, fi nding an average of 5.638 ± 5.935 after periodontal treatment. Conclusion: In patients who underwent non-surgical periodontal treatment, the concentration of ALT tends to decrease signifi cantly, however the results shown were not statistically significant (AU)

Effect of Scaling and Root Planing Treatment on Levels Hs-CRP in Indonesian Patients with Risk of Cardiovascular Disease

Objective: To determine the effect of scaling and root planning treatment on levels of hs-CRP (C-reactive protein) in patients with risk of cardiovascular disease. Material and Methods: This research is an experimental research with one group pre- and post-test design. This research was performed to the periodontal patients who came to the clinic and have risk of cardiovascular disease. Medical evaluations included measurement of blood pressure and body mass index were performed. Blood samples were obtained from each subject after over night fasting, highsensitivity C-reactive protein was measured as an index of inflammation. Blood samples were analysed two times before treatment (scaling and root planning) and three weeks later. Statistical analysis used Paired t-test. The level of significance was set at 5%. Results: Means-CRP levels before and after treatment in scaling and root planning were 3.16 ± 2.37 and 2.18±1.56 (p=0.007). Conclusion: There are significant differences between hs-CRP levels before and after treatment.

Comparison of full-mouth scaling and quadrant-wise scaling in the treatment of adult chronic periodontitis

Abstract In the search for the ideal treatment of periodontal disease various non-surgical techniques should be considered. The objective of this study was to evaluate the efficacy of full-mouth scaling (FMS) by clinical and microbiological parameters. 670 individuals were evaluated with 230 subjects meeting the selection criteria and were divided into two groups; 115 subjects treated with FMS and 115 treated with weekly sessions of scaling and root planning (SRP). The patient population had a mean age of 51.67 years, with moderate chronic periodontitis. Subjects were evaluated prior to treatment (T1) and 90 days after execution of therapy (T2), with regards to: probing depth (PD), clinical attachment level (CAL), plaque index (PI), gingival index (GI), and microbial detection for the presence of Porphyromonas gingivalis (P.g.) and Prevotella intermedia (P.i.) by culture method and confirmed by biochemical tests. Subjects treated in the FMS group also rinsed with 0.12% chlorhexidine mouthwash for seven days following treatment. The results were analyzed using statistical Student's t-test and chi-square test. No statistically significant differences were observed for PD and CAL between T1 and T2 in both groups. For GI and PI significant difference was observed between the groups. For the evaluated microbial parameters was observed reduction of P.g. and P.i., but only for P.g. with a significant reduction in both groups. The full mouth scaling technique with the methodology used in this study provided improved clinical conditions and reduction of P.g. in subjects with moderate periodontitis, optimizing the time spent in the therapeutic execution.

Resumo Na busca do tratamento ideal da doença periodontal varias são técnicas não-cirúrgicas que podem ser consideradas. O objetivo deste estudo foi avaliar a eficácia da técnica de desinfecção total de boca (FMD, na sigla em Inglês) por parâmetros clínicos e microbiológicos. Foram avaliados 670 indivíduos com 230 indivíduos atendendo aos critérios de seleção e divididos em dois grupos; 115 indivíduos tratados com FMD e 115 tratados com sessões semanais de raspagem e alisamento corono radicular (SRP, na sigla em Inglês). A população avaliada tinha idade média de 51,67 anos, com periodontite crônica moderada. Os sujeitos foram avaliados antes do tratamento (T1) e 90 dias após a execução da terapia (T2), quanto à profundidade de sondagem (PS), nível de inserção clínica (NIC), índice de placa (IP), índice gengival (IG) e detecção microbiana da presença de Porphyromonas gingivalis (P.g.) e Prevotella intermedia (P.i.) por método de cultura e confirmada por testes bioquímicos. Os indivíduos tratados no grupo FMD também realizaram bochechos com clorexidina 0,12% durante sete dias após o tratamento. Os resultados foram analisados ​​utilizando o teste estatístico t de Student e o teste de qui-quadrado. Não foram observadas diferenças estatisticamente significativas para PS e NIC entre T1 e T2 em ambos os grupos. Para IG e IP observou-se diferença significativa entre os grupos. Para os parâmetros microbianos avaliados foi observada redução de P.g. e P.i., mas apenas para P.g. com uma redução significativa em ambos os grupos. A técnica FMD com a metodologia utilizada neste estudo proporcionou condições clínicas melhoradas e redução da P.g. Em indivíduos com periodontite moderada, otimizando o tempo gasto na execução terapêutica.

Efect of Anaheal (Bromelain) Drug on the Periodontal Clinical Indices in Nonsurgical Periodontal Treatment of Patients with Chronic Periodontitis

Objective: To evaluate the effect of Anaheal (Bromelain) drug on the periodontal clinical indices in nonsurgical periodontal treatment of patients with chronic periodontitis. Material and Methods: In this double blind clinical trial, 80 patients with chronic moderate periodontitis and a healthy systemic status were chosen, and divided into two 40-subject groups. Thereafter, the standard treatment of periodontitis including scaling and root planning in one session by the unit operator was performed for all patients. Eventually, one group of the patients was administered Bromelain medication (500-mg capsule twice a day) one hour before food, while the other group was given placebo. Four and eight weeks after the treatment, the clinical periodontal indicators were measured and recorded in both groups. The data were assessed using descriptive statistics and analytical test methods (Mann-U-Whitney and Chi-square). P value less than 0.05 was considered statistically significant. Results: Gingival index, probing depth and plaque index before the treatment were similar in both groups (Anaheal and placebo). However, four and eight weeks after the treatment, the three studied indices were significantly lower in the Anaheal group as compared to the placebo (p<0.05). The index of bleeding on probing was also similar before the treatment and four weeks after the treatment in both groups. However, eight weeks after the treatment, this index was significantly lower in the Anaheal group as compared to the placebo group (p<0.05). Conclusion: Administration of oral Anaheal medication after nonsurgical periodontal treatments reduced all the clinical periodontal indices among patients with chronic periodontitis as compared to the control group. Therefore, it can be a suitable substitute for the common oral industrial antibiotics.

Effects of diode laser application on inflammation and mpo in periodontal tissues in a rat model

Abstract Objective In this study, we aimed to histologically and immunologically evaluate the effect of diode laser treatment when applied adjunctive to scaling and root planing (SRP) in an experimental periodontitis model. Materials and methods We used Wistar-Albino rats (n=60) with average weight of 230 g. Experimental periodontitis was induced by ligature at the right and left first mandibular molar teeth in all rats. After 11 days, the ligature was removed and rats were divided into two groups. The control group (n=30) received only SRP treatment, while the laser group (n=30) received a diode laser (GaAlAs, 810 nm, 1 W, 10 J, 20 s) treatment adjunctive to SRP. Ten rats in each group were sacrificed after 7, 15, and 30 days. Histopathological examination was performed in the left mandible of rats. Myeloperoxidase (MPO) was evaluated by western blot in the gingival specimens from the right mandible. Results MPO levels in the laser group were statistically significantly lower compared with the control group (p≤0.05). There was no statistically significance at any time between MPO levels in the control group (p>0.05). MPO levels in the laser group at the 7th day were statistically significantly higher compared to the 15th (p≤0.05) and the 30th day (p≤0.05). Inflammatory cell infiltration decreased over time in both groups and was statistically significantly lower in the laser group than in the control group at all times (p≤0.01). Conclusions Within the limits of this study, we suggest that diode laser application is an adjunctive treatment because it reduced inflammation and MPO when applied in addition to SRP. On the other hand, more studies are needed for the assessment of the effects of diode laser application to periodontal tissues.

Effect of non-surgical periodontal therapy on the degree of gingival inflammation and stress markers related to pregnancy

Abstract Objectives The purpose of this study was to determine the impact of nonsurgical periodontal therapy considering the salivary stress-related hormone and cytokine levels in the gingival crevicular fluid (GCF) on pregnant and nonpregnant women. Material and Methods Thirty non-pregnant (control group) and 30 pregnant women (test group) that met the study inclusion criteria were chosen. Only participants with gingivitis were included. Clinical data and samples of GCF and saliva were collected at baseline and after periodontal therapy. The levels of interleukin-1 beta (Κ-1β) and IL-10, and concentration of salivary chromogranin A (CgA) hormone were analyzed by enzyme-linked immunosorbent assay (ELISA). The repeated measures analysis of variance was used for intragroup and intergroup analyses. Results A major decrease in the gingival inflammation was observed in both groups after periodontal therapy (p<0.05). Periodontal treatment decreased the level of IL-1β in GCF (p<0.05) in control group, but no statistical difference was determined for GCF IL-1β in the test group. However, after periodontal therapy, the CgA hormone concentration was reduced in both groups (p<0.05). However, there was no difference in salivary CgA concentration, GCF IL-10 levels, and perceived stress scale (PSS)-10 between the groups (p>0.05). Conclusions Within the limitations of this study, periodontal therapy significantly improved the periodontal status and stress level. In addition, the severity of the gingival inflammation during pregnancy was related to stress. However, further studies will be needed to substantiate these early findings.

Microbiological and clinical effects of probiotics and antibiotics on nonsurgical treatment of chronic periodontitis: a randomized placebo- controlled trial with 9-month follow-up

ABSTRACT Objective: The aim of this double-blind, placebo-controlled and parallel- arm randomized clinical trial was to evaluate the effects of Lactobacillus rhamnosus SP1-containing probiotic sachet and azithromycin tablets as an adjunct to nonsurgical therapy in clinical parameters and in presence and levels of Tannerella forsythia, Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans. Material and Methods: Forty-seven systemically healthy volunteers with chronic periodontitis were recruited and monitored clinically and microbiologically at baseline for 3, 6 and 9 months after therapy. Subgingival plaque samples were collected from four periodontal sites with clinical attachment level ≥1 mm, probing pocket depth ≥4 mm and bleeding on probing, one site in each quadrant. Samples were cultivated and processed using the PCR technique. Patients received nonsurgical therapy including scaling and root planing (SRP) and were randomly assigned to a probiotic (n=16), antibiotic (n = 16) or placebo (n = 15) group. L. rhamnosus SP1 was taken once a day for 3 months. Azithromycin 500mg was taken once a day for 5 days. Results: All groups showed improvements in clinical and microbiological parameters at all time points evaluated. Probiotic and antibiotic groups showed greater reductions in cultivable microbiota compared with baseline. The placebo group showed greater reduction in number of subjects with P. gingivalis compared with baseline. However, there were no significant differences between groups. Conclusions: The adjunctive use of L. rhamnosus SP1 sachets and azithromycin during initial therapy resulted in similar clinical and microbiological improvements compared with the placebo group.

Tratamiento de las repercusiones sinérgicas en presencia de enfermedad periodontal en el paciente con diabetes: revisión de la literatura / Treatment of the synergistic effects of periodontaldisease in patients with diabetes. literature review

Introducción: La interacción de las enfermedades periodontales serelacionan con el medio ambiente, huésped, factores microbianos ysusceptibilidad genética. En esta patología la interacción de las bacteriasy el sistema inmunológico dan como resultado una producción elevada de mediadores infl amatorios como las interleucinas IL-1, IL-6 y el TNF-α que destruirán el tejido conectivo y óseo. La diabetes por sí misma ya sea tipo 1 o 2 va a tener repercusiones a nivel de los diferentes órganos de la economía como los riñones, sistema nervioso,ojos, sistema circulatorio y de ahí al periodonto. Cuando el paciente nose encuentra en control sistémico, los efectos adversos van aumentandoy se provoca una sinergia entre la alteración glucémica y la afectaciónperiodontal. Se ha descrito la relación del efecto benéfi co del tratamientoperiodontal en el control glucémico en pacientes diabéticos y no diabéticos. Conclusión: El tratamiento periodontal no quirúrgico demostró reducir los valores de los parámetros periodontales así como los valores séricos de glucosa en ayuno y hemoglobina glucosilada y coadyuvar en el control glucémico.

Introduction: The interaction of periodontal disease is related to theenvironment, host, microbial factors and genetic susceptibility. In thiscondition, the interaction of bacteria and the immune system result inincreased production of infl ammatory mediators such as IL-1, IL-6interleukins, and TNF-α that will destroy connective tissue and bone.Diabetes itself either type 1 or 2 will have repercussions at the levelof the diff erent organs of the economy as it is kidneys, nervous system,eyes, circulatory system and hence the periodontium. When the patientis not in controlling systemic adverse eff ects are increased and synergybetween periodontal health and glycemic involvement provoked. It hasbeen reported regarding the benefi cial eff ect of periodontal treatmenton glycemic control in diabetic and non-diabetic patients. Conclusion:The non-surgical periodontal treatment was shown to reduce the valuesof periodontal parameters and serum fasting glucose and glycatedhemoglobin and assist in glycemic control.

Treatment of experimental periodontal disease by laser therapy in simvastatin-modified rats

Abstract Low intensity laser can be used as a promising alternative in the treatment of periodontal disease. Objective The aim of this study was to evaluate low-level laser therapy (LLLT) as an adjuvant treatment for scaling and root planing (SRP) for the treatment of induced periodontitis in simvastatin-modified rats. Material and Methods A total of 180 rats were evenly divided into two groups: Veh - receiving oral administration of polyethylene glycol (vehicle); S - receiving oral administration of Simvastatin. Periodontal disease was induced in both groups at the first mandibular molar. After seven days, the ligature was removed and the animals were divided into subgroups according to the following local treatments: NT - no treatment; SRP - scaling and root planing and irrigation with saline solution; and LLLT ¬- SRP and laser irradiation (660 nm; 0.03 W; 4 J). Ten animals in each subgroup/local treatment were euthanized at 7, 15 and 30 days. Samples of gingival tissue were processed to analyze the tissue oxidative damage and radiographic analysis. Levels of oxidative stress were analyzed by the expressions of Tripeptideglutathione (TG), Malondialdehyde (MDA) and Carbonylated Proteins (CP). Results The animals in S group had higher levels of TG and lower levels of MDA and CP compared with Veh group (p<0.05). Radiographically, in the intragroup analysis Veh and S, LLLT showed lower bone loss (BL) compared with NT and SRP, in all experimental periods (p<0.01). In addition, a lower BL was observed for the animals of Veh group treated with LLLT compared with treatment SRP in the S group, in all experimental periods. Conclusion Within the limits of this study, we can conclude that LLLT was effective as adjuvant treatment for SRP protecting against the occurrence of oxidative tissue damages as well as for reducing alveolar bone loss in experimentally induced periodontitis simvastatin-modified rats.

Role of 1% alendronate gel as adjunct to mechanical therapy in the treatment of chronic periodontitis among smokers

Abstract Objective Alendronate (ALN) inhibits osteoclastic bone resorption and triggers osteostimulative properties both in vivo and in vitro, as shown by increase in matrix formation. This study aimed to explore the efficacy of 1% ALN gel as local drug delivery (LDD) in adjunct to scaling and root planing (SRP) for the treatment of chronic periodontitis among smokers. Material and Methods 75 intrabony defects were treated in 46 male smokers either with 1% ALN gel or placebo gel. ALN gel was prepared by adding ALN into carbopol-distilled water mixture. Clinical parameters [modified sulcus bleeding index, plaque index, probing depth (PD), and periodontal attachment level (PAL)] were recorded at baseline, at 2 months, and at 6 months, while radiographic parameters were recorded at baseline and at 6 months. Defect fill at baseline and at 6 months was calculated on standardized radiographs by using the image analysis software. Results Mean PD reduction and mean PAL gain were found to be greater in the ALN group than in the placebo group, both at 2 and 6 months. Furthermore, a significantly greater mean percentage of bone fill was found in the ALN group (41.05±11.40%) compared to the placebo group (2.5±0.93%). Conclusions The results of this study showed 1% ALN stimulated a significant increase in PD reduction, PAL gain, and an improved bone fill compared to placebo gel in chronic periodontitis among smokers. Thus, 1% ALN, along with SRP, is effective in the treatment of chronic periodontitis in smokers.

Effect of 1% sodium alendronate in the non-surgical treatment of periodontal intraosseous defects: a 6-month clinical trial

Abstract Background and objectives Few studies have evaluated the effect of the topical application of sodium alendronate (ALN) on the treatment of intrabuccal bone defects, especially those caused by periodontitis. This 6-month randomized placebo controlled clinical trial aimed at evaluating the effect of non-surgical periodontal treatment associated with the use of 1% ALN, through clinical evaluations and cone-beam computed tomography (CBCT). Material and Methods Twenty individuals with chronic periodontitis underwent periodontal examination at the baseline as well as 3 and 6 months after periodontal treatment, registering clinical attachment level (CAL), periodontal probing depth (PPD), and bleeding on probing (BOP) as the clinical outcomes. After manual scaling and root planing, 40 bilateral sites with interproximal vertical bone defects were randomly treated with either 1% ALN gel or a placebo. Bone defects were evaluated through CBCT at the baseline and 6 months post-treatment. The clinical and CBCT parameters were compared using the Wilcoxon and Friedman tests (p<0.05). Results Although ALN produced a greater CAL gain when compared to the placebo at 6 months post-treatment (p=0.021), both treatments produced similar effects on the PPD, BOP, and bone height. Significant differences in bone fill were observed only in patients of the ALN group (4.5 to 3.8 mm; p=0.003) at 6 months post-treatment. Conclusions Topical application of 1% ALN might be a beneficial adjuvant to non-surgical periodontal therapy.

Microbiological outcomes from different periodontal maintenance interventions: a systematic review

Abstract This study aimed to investigate the differences in the subgingival microbiological outcomes between periodontal patients submitted to a supragingival control (SPG) regimen as compared to subgingival scaling and root planing performed combined with supragingival debridement (SPG + SBG) intervention during the periodontal maintenance period (PMP). A systematic literature search using electronic databases (MEDLINE and EMBASE) was conducted looking for articles published up to August 2016 and independent of language. Two independent reviewers performed the study selection, quality assessment and data collection. Only human randomized or non-randomized clinical trials with at least 6-months-follow-up after periodontal treatment and presenting subgingival microbiological outcomes related to SPG and/or SPG+SBG therapies were included. Search strategy found 2,250 titles. Among these, 148 (after title analysis) and 39 (after abstract analysis) papers were considered to be relevant. Finally, 19 studies were selected after full-text analysis. No article had a direct comparison between the therapies. Five SPG and 14 SPG+SBG studies presented experimental groups with these respective regimens and were descriptively analyzed while most of the results were only presented graphically. The results showed that both SPG and SPG+SBG protocols of PMP determined stability in the microbiological results along time. Nevertheless, new studies comparing these interventions in PMP are needed, especially if the limitations herein discussed could be better controlled.

Comparison of Er:YAG laser and ultrasonic scaler in the treatment of moderate chronic periodontitis: a randomized clinical trial

Introduction: Periodontitis is an inflammatory periodontal disease that leads to tooth loss. Recently laser has been introduced as an alternative treatment for periodontitis. The aim of the present study was to compare the effect of Erbium-doped Yttrium Aluminum Garnet [Er:YAG] laser with ultrasonic scaler in patients with moderate chronic periodontitis

Methods: In this randomized single-blind clinical trial, 27 patients with moderate chronic periodontitis were selected. One quadrant of the patients was treated by Er:YAG laser and the other one by ultrasonic scaler. Clinical parameters, including periodontal pocket depth [PPD], papillary bleeding index [PBI] and clinical attachment level [CAL] were measured before, as well as 6 and 12 weeks after treatment. Data were analyzed by SPSS 20 software using Friedman test, paired t test, independent t test and Mann-Whitney test. The significance level was set at 0.05

Results: The means of clinical parameters in both groups were significantly improved in the first and second follow-ups [P < 0.001]. Although the means of PPD, PBI and CAL were slightly higher in the laser group than in the ultrasonic group, the differences were not statistically significant between these two groups [P > 0.05]

Conclusion: Although both ultrasonic scaler and Er:YAG laser could effectively improve clinical periodontal parameters, the results did not reveal the superiority of Er:YAG laser over ultrasonic scaler or vice versa
