Effects of non-surgical periodontal therapy combined with emodin on insulin resistance and serum inflam-matory factors in obese rats / 实用医学杂志

Objective To investigate the effect of emodin on insulin resistance and serum inflammatory factors in obese rats. Methods 16 obese rats with experimental periodontitis were selected and then randomly di-vided into periodontal treatment group(control group)and periodontal therapy combined with emodin group(medi-cation group). All the rats were sacrificed 2 weeks after treatment. Before the rats were killed,the orbital vein blood was taken to detect fasting blood glucose,fasting insulin;levels of serum C-reactive protein(CRP)and tu-mor necrosis factor-α(TNF-α)were detected by enzyme linked immunosorbent assay.Results 2 weeks after peri-odontal treatment,level of CRP was significantly lower in the medication group than in the control group(t =2.170,P = 0.044);TNF-α was significantly lower in the medication group than in the control group(t = 3.074, P=0.007).Fasting blood glucose level was lower in the medication group than in the control group,and HOMA-β was higher than the control group,no statistical differences were found between the two groups.Conclusions Non-surgical periodontal treatment combined with local administration of emodin can help repair of periodontal epitheli-al barrier and reduce levels of serum inflammatory factors.

Eficacia de terapia fotodinámica como complemento de terapia convencional periodontal versus terapia convencional en el tratamiento de pacientes adultos con periodontitis crónica: una revisión sistemática con metaanálisis / Effectiveness photodynamic therapy complementing conventional periodontal therapy versus conventional therapy in the treatment of adult patients with chronic periodontitis: a systematic review with meta-analyses

Se evaluó la eficacia de la terapia fotodinámica como complemento de terapia periodontal convencional comparándola con la terapia convencional en el tratamiento de sacos periodontales en pacientes adultos con periodontitis crónica basándose en ensayos clínicos comprendidos entre los años 2010 y 2015, para determinar si su uso otorga mejores resultados para el tratamiento de esta enfermedad. Se seleccionaron ensayos clínicos aleatorios prospectivos, aleatorizados o no aleatorizados, controlados y no controlados que permitieron la comparación entre el tratamiento convencional y la terapia fotodinámica, con un grupo en el cual se utilizó sólo la terapia convencional. Los datos de los ensayos clínicos fueron ingresados al software Review Manager®. Se realizaron tres metaanálisis para las variables: Nivel de inserción clínica (NIC) y profundidad de sondaje (PS), el test de I2 fue utilizado para medir la heterogeneidad del estudio y posteriormente un análisis de sensibilidad para determinar los estudios heterogéneos. Se pudieron analizar 7 estudios, con un total de 186 pacientes, quienes fueron controlados 3 meses post tratamiento. Se utilizó la diferencia de medias, un intervalo de confianza de 95 % para medir el NIC y PS. A los 3 meses, no se encontró diferencias significativas en NIC (p= 0,93) y PS (p= 0,71). Conclusión: La terapia fotodinámica en complementación a la terapia convencional no otorga mejor resultado clínico ni estadístico comparado con la terapia convencional al evaluar el nivel de inserción clínica. Al evaluar la profundidad de sondaje es recomendable la utilización de terapia convencional sola.

The efficacy of photodynamic therapy as an adjunct to conventional periodontal therapy evaluated by comparing with conventional therapy alone in the treatment of periodontal pockets in adult patients with chronic periodontitis based on clinical trials between 2010 and 2015, to determine if its use can provide better results for treating this disease. Prospective randomized clinical trials and randomized clinical trials or non-randomized, controlled and uncontrolled that allowed comparison between a group which was applied to conventional therapy and photodynamic therapy, a similar group was selected to which you He applied only conventional therapy. Data from clinical trials entered into Review Manager®. Three meta-analyzes for the variables analyzed were performed: Level clinical attachment (NIC) and probing depth (PS), the test of I2 was used to measure the heterogeneity of the study and then a sensitivity analysis to determine which studies awardedheterogeneity. As results, seven studies analyzed in 186 patients who underwent treatment at least controlled within 3 months post treatment. The mean difference was used, a confidence interval of 95 % to measure the NIC and PS. At 3 months, no significant differences in NIC (p= 0.93) and PS (p= 0.71). In conclusion, the photodynamic therapy complementary to conventional therapy does not provide better clinical or statistical results compared with conventional therapy to evaluate the clinical attachment level. In assessing probing depth, is advisable to use conventional therapy alone.

Tratamiento periodontal no quirúrgico en pacientes con gingivitis y periodontitis moderada. Respuesta bioquímica y microbiológica / Non surgical periodontal treatment in patients with gingivitis and moderate periodontitis. Biochemical and microbiological response

Objetivo: Conocer la respuesta inflamatoria a través de la presencia de interleucina 1β e identificar microorganismos patógenos como posibles marcadores inmunológicos y microbiológicos en el diagnóstico y tratamiento periodontal no quirúrgico en sujetos con gingivitis y periodontitis crónica moderada en población mexicana. Material y métodos: En este estudio prospectivo de cohortes, se seleccionaron 18 pacientes con signos clínicos de gingivitis y 17 pacientes con periodontitis crónica moderada, se recolectaron las muestras de biopelícula subgingival y de fluido gingival crevicular. Se cuantificó la interleucina 1β durante las fases pretratamiento, postratamiento y de mantenimiento del tratamiento periodontal no quirúrgico. Resultados: Las variables de respuesta microbiológica mostraron que Porphyromonas gingivalis, Prevotella intermedia, Fusobacterium nucleatum, Aggregatibacter actinomycetemcomitans disminuyeron significativamente en individuos con gingivitis. Así como Porphyromonas gingivalis, Tannerella forsythia, Fusobacterium nucleatum, Aggregatibacter actinomycetemcomitans y Actinomyces sp. en periodontitis crónica moderada. Las variables de respuesta bioquímica mostraron una disminución significativa en la concentración y cuenta total de interleucina 1β en los individuos con periodontitis crónica moderada en la fase de mantenimiento del tratamiento así como de las variables de respuesta clínica. Conclusión: Hay reducción de los niveles de interleucina 1β con la disminución de la microflora. Los niveles de interleucina 1β son marcadores sensibles para el diagnóstico y severidad de la enfermedad periodontal.

Objective: To ascertain inflammatory response through interleucina 1β presence and identify pathogenic microorganisms as possible immunological and microbiological markers in diagnosis and treatment non-surgical periodontal in patients with gingivitis and moderate chronic periodontitis in a sample of Mexican population. Material and methods: In the present prospective cohort study, 18 patients with signs of gingivitis and 17 patients with moderate chronic periodontitis were selected. Samples of subgingival biofilm and of crevicular gingival fluid were collected. Interleukine 1β was quantified during the pre-treatment, post-treatment and maintenance phases of the nonsurgical periodontal treatment. Continuous variables were analyzed with the Student test, as well as categorical variables which were analyzed with the TurkeyKramer test. For independent groups the Pearson test was used. Results: Microbiological response variables showed that Porphyromonas gingivalis, Prevotella intermedia , Fusobacterium nucleatum , Aggregatibacter actinomycetemcomitans significantly decreased in subjects with gingivitis. Porphyromonas gingivalis , Tannerella forsythia , Fusobacterium nucleatum , Aggregatibacter actinomycetemcomitans and Actinomyces ssp . decreased in cases. Biochemical response variables showed significant decrease in IL-1β concentration and total count in individuals with moderate chronic periodontitis in treatment maintenance phase. The same result applied to clinical response variables. Conclusions: There is a decrease in Interleukin 1β levels with decrease in microflora. Interleukin 1β are sensitive markers for diagnosis of periodontal disease and assessment of its severity.

Assessment of the quality of life and oral health status in diabetic patients / 대한구강보건학회지

OBJECTIVES: The aim of this study was to investigate changes in the quality of life and oral health status in diabetic patients as a result of non-surgical periodontal treatments. METHODS: In total, 55 diabetic patients who visited the health care center at our institution participated in this study. The patients were divided randomly into 3 groups as follows: scaling and root planning (SRP), professional maintenance care (PMC), and control (CT). The patients were asked to answer the Short-Form-36 Health Survey (SF-36) to evaluate their quality of life, and two examiners evaluated the patients' oral health status before and after the periodontal treatments. To evaluate the oral health status, the current number of teeth, DMFT index, bleeding on probing rate (BOP), pocket depth (PD), and calculus index (CI) were used. Statistical analyses were conducted using SPSS with appropriate sampling weights to adjust for the stratified sample design. RESULTS: In both the SRP and PMC groups, the BOP and CI decreased after the treatment (P<0.05). In the SRP group, physical functioning and the mental health score increased (P<0.05). CONCLUSIONS: According to the results, non-surgical periodontal treatment in diabetic patients is effective in increasing the health-related quality of life.

Non-surgical Treatment of Peri-implant Inflammation with the Adjunctive Use of the Diode Laser (810nm) Case Presentation.

Objective: The aim of this study is to discuss the non-surgical periodontal instrumentation, (which is necessary and irreplaceable) with the adjuctive use of diode laser (810nm), in the treatment of peri-implant infalmmation. Data are limited to a case report. Presentation of Case: After 12 years from implants insertion, which was carried out in 1992, a periodontally susceptible patient, shows signs of peri-implant inflammation (2004). Nowadays, after non-surgical periodontal laser-assisted therapy and 9 years of follow-up, implants shows no more signs of inflammation. Periodontal Therapy and Supportive Treatment are Made of Two Indispensable Phases: professional oral hygiene and home care instruction. During professional oral hygiene appointment, in addition to mechanical (dedicated ultrasonic inserts) and manual (titanium curette) non-surgical periodontal instrumentation, a diode laser in pulsed wave, at of 1Watt (2Watt the first appointment) for 20sec in duplicate at each site, was used. Professional treatment included also air polishing with glycine powder and application of CHX 0,5%gel. The patient was instructed in proper home care. Discussion and Conclusion: each treatment stage was carried out as required by the protocol and the patient has faithfully followed the oral hygiene instructions. Peri-implant clinical situation has remained fairly stable, showing normal periodontal parameters, more than 20 years from implants insertion. The present case shows how, traditional protocols of non-surgical periodontal therapy, in conjunction with the diode (810nm) laser, seem to be an effective alternative treatment modality in non-surgical treatment of peri-implantitis, in a periodontal susceptible patient. Obviously, data are limited the present case report and should be validated by further longitudinal clinical studies.after

Control Glucémico de Diabetes Mellitus y Tratamiento de Enfermedades Periodontales: Reporte de Dos Casos Clínicos / Diabetes Mellitus Glycemic Control and Treatment of Periodontal Diseases: Report of Two Cases

Las Enfermedades Periodontales afectan de forma adversa el control metabólico de Diabetes Mellitus. Se postula que si un paciente diabético mantiene salud periodontal a través del tratamiento periodontal no quirúrgico puede mejorar el control glucémico. Por lo tanto el identificar pacientes con enfermedad periodontal avanzada puede ser un elemento clínico relevante para sospechar de diabetes no diagnosticada y su tratamiento puede tener un efecto positivo en el control metabólico de la diabetes, medido a través de los niveles de hemoglobina glucosilada (HbA1c). En el primer caso se da seguimiento a un paciente con Diabetes Mellitus tipo 1 y en el segundo reporte clínico a un paciente con Diabetes Mellitus tipo 2, con el objetivo de observar si el tratamiento periodontal mejora el control glucémico. Después del tratamiento periodontal no quirúrgico, en ambos casos clínicos existió disminución de hemoglobina glucosilada (HbA1c) teniendo un efecto positivo el tratamiento periodontal en el control metabólico medido a través de los niveles de hemoglobina glucosilada (HbA1c).

Periodontal Diseases affect Diabetes Mellitus metabolic control adversely. It is stated that if a diabetic patient keeps his/her periodontal health by means of a non-surgical periodontal treatment, his/her glycemic control can improve. Therefore, to identify patients with advanced periodontal diseases it can be a relevant clinical element to suspect a non-diagnosed diabetes and its treatment can have a positive effect on the diabetes metabolic control, measured through glycosylated hemoglobin levels (HbA1c). In the first case, a patient with Diabetes Mellitus type 1 is followed up, and in the second clinical report a patient with Diabetes Mellitus type 2 was followed up with the purpose of observing whether the periodontal treatment improves glycemic control. After the non-surgical periodontal treatment, there was a glycosylated hemoglobin decrease (HbA1c), with periodontal treatment having a positive effect on the metabolic control measured through glycosylated hemoglobin levels (HbA1c).

Avaliação do sucesso da terapia periodontal não cirúrgica. Follow up de período curto / Evaluation of the success of nonsurgical periodontal therapy. Short time follow-up

Objetivo: Avaliar o sucesso do tratamento periodontal não cirúrgico após 6 meses da conclusão da terapia periodontal. Materiais e Métodos: um total de 11 indivíduos foi selecionado com base em critérios previamente estabelecidos de modo a assegurara consistência dos resultados. Os exames supragengivais e subgengivais consideraram o índice de placa visível (IPV); o índice de sangramento gengival (ISG); a profundidade de sondagem(PS), o nível clínico de inserção (NIC) e sangramento a sondagem (SS) obtidos no início e no final do tratamento. Os dados foram agrupados em faces livres (vestibular e lingual) e faces proximais (mesial e distal), sendo comparados os resultadosdos exames iniciais com os exames finais, realizados no estudo. Os testes estatísticos utilizados foram: o teste T de Studente o teste Qui-Quadrado, ambos para uma significância de5%. Resultados: verificou-se que os pacientes apresentaram redução de todos os parâmetros clínicos analisados, confirmado pela média dos indicadores IPV, ISG, SS, PS e NIC dos pacientes tratados. Conclusão: foi observado melhora nos indicadores de saúde periodontal, após três meses da terapia periodontal não cirúrgica, isentando os pacientes do desconforto pós-cirúrgico e sem afetar o sistema imunológico dos mesmos, através de antibióticoterapia.

Aim: The aim of this study was to evaluate the success of nonsurgical periodontal treatment after 6 months of completion of periodontal therapy. Material and Methods: A total of 11 individuals was selected based on criteria established in advance in order to ensure consistency of results. Tests supragingival and subgingival considered the visible plaque index (VPI), the gingival bleeding index (GBI), probing depth (PD) and clinical attachment level (NIC), obtained at the beginning and end of treatment. The data were grouped into free faces (facial and lingual) and proximal surfaces (mesial and distal) and compared the resultsof initial tests with the final exams in the study. Statistical tests used were Student's t test and chi-square test, both for a 5% significance. Results: we found that patients showed a reduction in all clinical parameters were analyzed and confirmed by theaverage indicators of IPV, SS, PS and NIC of patients treated by exempting them from the post-surgical discomfort and without affecting the immune system of individuals. Conclusion: There was improvement in indicators of periodontal health, after thee valuation of six months of nonsurgical periodontal therapy, freeing patients from the discomfort after surgery and without affecting the immune system of the same.

Root Dentine Sensitivity.

Background: Dentine hypersensitivity is one of the most painful, ubiquitous and least satisfactorily treated of all the chronic oral problems involving the teeth. Active Periodontal treatment appears to be one of the significant causes of hypersensitivity. Also, the role of plaque control in treatment of hypersensitivity is controversial. Thus the present study is aimed to study the degree to which a sample of patient developed Root Dentine Sensitivity (RDS) following nonsurgical periodontal treatment. Material & Methods: A total of 60 dental patients were evaluated for plaque scores and pain scoring using Scratch test and Air blast test. Visual Analogue Scale (VAS) was used for pain scoring. Oral hygiene instructions were given and non- surgical periodontal treatment was done quadrant wise over a period of 4 weeks. Results: The intensity of RDS given by VAS score and the percentage of teeth sensitive to both the test increased after scaling and root planing but gradually decreased when meticulous plaque control was maintained. Conclusion: Non- surgical periodontal treatment i.e. SRP and Oral hygiene maintenance may temporarily increase RDS, which reduces subsequently over a period of time with meticulous plaque control.

Efeitos do tratamento periodontal não cirúrgico sobre a densidade e altura óssea alveolar / Effects of non surgical periodontal treatment on the alveolar bone dentity

O objetivo deste trabalho foi avaliar o efeito do tratamento periodontal não cirúrgico (TPNC), na densidade e na altura óssea alveolar, em pacientes com periodontite, utilizando radiografias digitais diretas. Cento e um sítios, em dezenove pacientes (idade média 36 ± 7.3 anos) foram acompanhados no dia 0, e 90 e 180 dias após TPNC. Os índices clínicos de profundidade de bolsa a sondagem (PBS), nível de inserção clínica, sangramento à sondagem e índice de placa foram registrados e radiografias digitais foram feitas. A densidade foi analisada através de regiões ósseas de interesse colocadas sobre a crista óssea alveolar (ROI I) e sobre o osso medular (ROI II). A altura óssea alveolar foi medida através da distância da crista óssea alveolar até a junção cemento esmalte. Os sítios profundos (PBS ≥ 5mm) apresentaram uma melhora clínica significante (p <0.01), acompanhada de um aumento na densidade da ROI I (p <0.01). A ROI II mostrou um aumento na densidade dos sítios com PBS ≤ 3mm em pacientes com periodontite agressiva (p <0.05). No entanto, houve diminuição nos sítios com PBS ≥ 5mm nesses mesmos pacientes (p <0.03). A altura óssea alveolar não sofreu alteração após TPNC. Após o tratamento periodontal não cirúrgico, observou-se que as radiografias obtidas através da técnica digital direta parecem mostrar um aumento na densidade da crista óssea, nos sítios profundos dos pacientes com periodontite. No entanto, a redução da profundidade de bolsa e do ganho no nível de inserção clínica não foi acompanhada por alterações significantes na altura óssea alveolar nestes sítios.

The aim of this study was to access the effects of non-surgical periodontal treatment (NSPT), on the bone density and alveolar bone height (ABH), in patients with periodontitis, using direct digital radiographs. One hundred one sites in nineteen patients (mean age 36 ± 7.3 years) were accompanied on day 0, and 90 and 180 days after the TPNC. The clinical scores of probing pocket depth (PPD), clinical attachment level, bleeding on probing and plaque index were registered and digital radiographs were taken. The density was accessed considering the bone regions of interest at the alveolar bone crest (ROI I) and the medullar bone (ROI II). The ABH measured the distance between the alveolar bone crest and the cementoenamel junction. The deep sites (PPD ≥ 5mm) presented a clinical improvement (p <0.01), accompanied by an increase in bone density at ROI I (p <0.01). ROI II showed an increase in density at sites with PPD ≤ 3mm in patients with aggressive periodontitis (p <0.05). However, there was a decrease in density in sites with PPD ≥ 5mm of the same patients (p <0.03). The ABH didn´t change after TPNC. After non-surgical periodontal treatment, the direct digital radiographs showed a significant increase in bone crest density of deep sites in patients with periodontitis. Moreover, the reduction in the probing pocket depth and the increase in the attachment level were not followed by changes in alveolar bone height in these sites.

Relationship between periodontitis and rheumatoid arthritis and the effect of non-surgical periodontal treatment

This study analyzed the association of periodontal disease (PD) and rheumatoid arthritis (RA). Seventy-five 35-60-year-old patients were assigned to 5 groups according to the presence (+) or not (-) of PD and RA and the treatment received (TR+) or not (TR-) for PD. Group 3 uses total prosthesis (TP). Clinical and laboratory evaluations were performed at baseline, 3 and 6 months of follow-up by probing pocket depth, bleeding on probing and plaque index for PD, HAQ, DAS28, SF-36 and laboratory: AAG, ESR, CRP for RA. Statistically significant differences for PD after 3 (p=0.0055) and after 6 months (p=0.0066) were obtained in Group 1 (RA+PD+TR+) and 2(RA+PD+TR-); significant reduction in the percent of BOP after 6 months (p=0.0128) and significant reduction in the percent of Pl after 3 (p=0.0128) and 6 months (p=0.0002) in Group 1. Statistically significant differences between Groups 1 and 3 (RA+TP) for DAS28 at baseline and after 3 months were observed, but not after 6 months. No other parameters for RA were significantly affected. The relationship between RA and PD disease activities is not clear, but the importance of periodontal treatment in the control of inflammation to avoid tooth extraction is evident.

Este estudo avaliou a influência da doença periodontal (DP) na artrite reumatóide (AR). 75 pacientes, 35-60 anos, divididos em 5 Grupos, considerando a situação sistêmica e periodontal foram analisados. Um Grupo usava prótese total (PT). Os parâmetros clínicos e laboratoriais analisados: inicial, 3 e 6 meses receberam tratamento estatístico. As correlações entre as reduções da profundidade de sondagem, placa microbiana e sangramento à sondagem com as de Alfa 1, PCR, VHS e exames de qualidade de vida (HAQ, DAS28, SF36) foram também analisadas. Comparando o Grupo 1 (AR+DP+TR+) e Grupo 2 (AR+DP+TR-), aqueles que receberam tratamento periodontal não-cirúrgico (TPNC) tiveram reduções estatisticamente significativas em relação a PS aos 3 meses (p=0,0055) e 6 meses (p=0,0066); as reduções da por cento SS foram estatisticamente significantes aos 6 meses (p=0,0128) e da por cento PM aos 3 (p=0,0128) e 6 meses (p=0,0002). O TPNC não apresentou correlação com a melhora dos exames laboratoriais, nem com os exames de qualidade de vida. Comparando o Grupo 1 com o Grupo 3 (AR+PT) houve diferença estatisticamente significante no DAS28 inicial e 3 meses. Não foi possível verificar uma correlação direta do TPNC na atividade da doença sistêmica, mas pode-se constatar a sua importância, evitando a extração múltipla dos dentes.
