Abordaje reconstructivo para un defecto de periimplantitis / Reconstructive approach for a peri-implantitis defect

Si bien el conocimiento científico para el tratamiento de la periimplantitis ha avanzado significativamente en los últimos años, sigue en discusión qué tipo de abordaje quirúrgico genera los mejores resultados clínicos y si el uso de biomateriales da mejoras significativas en dicho tratamiento. Este reporte de caso describe un abordaje quirúrgico reconstructivo de un defecto intraóseo por periimplantitis en una paciente que refería dolor y un intenso sangrado en sus implantes dentales, empleando un sustituto óseo anorgánico mineral bovino, sin el uso de una membrana o barrera, y con un protocolo de descontaminación de la superficie del implante mecánico y químico. Posteriormente, a las 20 semanas de realizado el procedimiento, se hizo la evaluación del defecto, obteniendo profundidades al sondeo menores a 5 mm, ausencia de sangrado al sondeo en todos los sitios y un llenado óseo radiográfico de aproximadamente 90%; cumpliendo con los criterios de éxito de la terapia periimplantaria. Lo anterior muestra que la terapia reconstructiva para los defectos por periimplantitis puede ser posible mediante el uso de un sustituto óseo xenogénico únicamente y con una correcta descontaminación de la superficie del implante (AU)

Although scientific knowledge for the treatment of peri-implantitis have advanced significantly in recent years, the type of surgical approach that generates the best clinical results is still under discussion and whether the use of biomaterials gives significant improvements in said treatment. This case report describes a reconstructive surgical approach for a periimplantitis intrabony defect using an anorganic bovine bone substitute, without the use of a membrane or barrier, and with a mechanical and chemical implant surface decontamination protocol. Twenty weeks after the procedure, the defect was reassessed, obtaining probing depths of less than 5 mm, no bleeding on probing in all sites, and radiographic bone filling of approximately 90%; meeting the success criteria for the peri-implant therapy. This shows that reconstructive therapy for periimplantitis defects may be possible using a xenogeneic bone substitute only and proper decontamination of the implant surface (AU)

The influence of periodontal status and serum biomarkers on salivary leptin levels in systemic lupus erythematosus patients.

Objective: This study aimed to investigate the influence of periodontal status, clinical data, and serum markers on salivary leptin levels in patients with systemic lupus erythematosus (SLE). Methods: A case-control study was conducted with 38 patients with SLE and 29 healthy controls. Periodontal data included periodontal probing depth (PPD), clinical attachment level (CAL), and gingival bleeding on probing (BOP). Stimulated saliva samples were collected to analyze salivary leptin levels. Clinical and serum data were collected from the SLE group. Statistical analysis included the t-test, Mann-Whitney test, Spearman correlation coefficient, and a structural equation model. Results: The SLE group had a lower salivary leptin level than the control group (P = 0.002). The model revealed that SLE had an inverse and independent effect on salivary leptin (standardized estimate =  - 0.289, P = 0.023). Moreover, salivary leptin level negatively correlated with the serum levels of triglyceride, creatinine, and leukocytes, positively correlated with the serum total cholesterol, but was not significantly correlated with the periodontal status. Conclusion: These findings suggest that patients with SLE have a lower salivary leptin level. In addition, the level of salivary leptin does not appear to be related to periodontal status in patients with SLE.

Peri-implant clinicoradiographic status among betel-quid chewers and controls

Abstract The aim of the present case-control observational study was to evaluate the peri-implant clinicoradiographic status among betel-quid chewers and controls. Self-reported betel-quid chewers and controls were included. Participants were categorized into 3 groups: Group-1: Individuals chewing betel-quid with tobacco; Group-2: Individuals chewing betel-quid without tobacco; and Group-3: Controls (individuals not using tobacco in any form). Demographic data was collected using a questionnaire. Periodontal and peri-implant clinicoradiologic parameters (plaque and gingival indices [PI and GI], probing depth [PD] and crestal bone loss/marginal bone loss [CBL/MBL]) were assessed. Clinical attachment loss (AL) around teeth was also assessed. Group comparisons were done using the one-way analysis of variance and Bonferroni Post-hoc adjustment tests. Correlation of periodontal and peri-implant inflammatory parameters with the duration of betel-quid chewing habit and duration of placement in the mouth were assessed using logistic regression analysis. P<0.05 was considered statistically significant. Thirty, 30 and 30 patients were included in groups 1, 2 and 3, respectively. Full-mouth PI (P<0.01), GI (P<0.01), clinical AL (P<0.01), PD (P<0.01) and mesial and distal MBL (P<0.01) were higher in groups 1 and 2 than Group-3. Peri-implant mPI (P<0.01), mGI (P<0.01), PD (P<0.01) and MBL/CBL (P<0.01) were significantly higher in groups 1 and 2 than Group-3 with no significant difference in groups 1 and 2. Betel-quid chewing habit either with or without tobacco is a risk-factor of peri-implant soft-tissue inflammation and CBL.

Resumo O objetivo do presente estudo observacional de casos-controles foi avaliar o estado clínico-radiográfico periimplantar dos usuários de bétele. Foram incluídos usuários que relataram utlizar a substância bétele como tabaco de mascar. Os participantes foram categorizados em 3 grupos: Grupo-1: Indivíduos que mascam bétele com tabaco; Grupo-2: Indivíduos que mascam bétele sem tabaco; e Grupo-3: Controle (indivíduos que não usam tabaco sob qualquer forma). Os dados demográficos foram recolhidos utilizando um questionário. Foram avaliados parâmetros clínico-radiográfico e periimplantares (índices placa e gengivais [IP e IG], profundidade de sondagem [PS] e perda de crista óssea/ perda óssea marginal [PCO/POM]). Também foi avaliada a perda inserção clínica (IC) em torno dos dentes. As comparações de grupo foram feitas utilizando a análise de variância unidireccional e os testes de ajustamento post-hoc de Bonferroni. A correlação dos parâmetros inflamatórios periodontais e periimplantares com a duração do hábito de mastigação da bétele e duração da colocação na boca foi avaliada utilizando a análise de regressão logística. P<0,05 foi considerado estatisticamente significativo. Foram utilizados 30 pacientes em cada grupo. O IP de boca inteira (P<0,01), IG (P<0,01), IC clínica (P<0,01), PS (P<0,01) e POM mesial e distal (P<0,01) foram mais elevados nos grupos 1 e 2 do que no grupo 3. O mPI peri-implantar (P<0,01), '(P<0,01), PD (P<0,01) e POM/PCO (P<0,01) foram significativamente mais elevados nos grupos 1 e 2 do que no grupo 3, sem diferença significativa nos grupos 1 e 2. O hábito de mastigar a substância bétele com ou sem tabaco é um fator de risco de inflamação dos tecidos moles periimplantares e PCO.

Condición Periodontal de los Dientes Temporales Adyacentes a la Hendidura Alveolar en Pacientes con Labio y Paladar Hendido Unilateral No Sindrómico, Hospital Nacional de Niños "Dr. Carlos Sáenz Herrera", Caja Costarricense de Seguro Social

RESUMEN: Los dientes adyacentes a la hendidura alveolar, en pacientes con labio y paladar hendido, presentan mayor incidencia de problemas periodontales, según la literatura. El objetivo de este trabajo fue evaluar si los dientes temporales adyacentes a la hendidura alveolar presentan mayor incidencia de problemas periodontales en niños con labio y paladar hendido unilateral completo no sindrómico, nacidos en 2010 y 2011, atendidos en el Hospital Nacional de Niños "Dr. Carlos Sáenz Herrera", Caja Costarricense de Seguro Social. Este estudio prospectivo, transversal, descriptivo, e intervencional evaluó variables epidemiológicas, clínicas y radiográficas (placa bacteriana, profundidad de bolsa, nivel de inserción, recesión gingival, sangrado, encía queratinizada e insertada, cálculo y movilidad dental, tipo de hendidura alveolar). Se utilizó técnicas de análisis estadísticos descriptivas (distribución de frecuencias, cruce de variables y construcción de intervalos de confianza). El análisis de datos y procesamiento estadístico se realizó en SPSS versión 17.0 y en Excel. El grupo constó de 17 pacientes, con edad promedio de 5 años. Se encontró 47 % de placa dental y 0 % de cálculo dental. La profundidad de bolsa y el sangrado fueron estadísticamente mayores para los dientes dentro de la hendidura alveolar. Los dientes adyacentes a la hendidura presentaron menor cantidad de encía queratinizada e insertada. Referente a la movilidad dental no existe diferencia estadísticamente significativa. Solo un diente presentó recesión gingival. La hendidura alveolar completa predominó radiográficamente. Los dientes cercanos a la hendidura alveolar tienen mayor predisposición a problemas periodontales, por lo que es relevante el seguimiento regular de la salud periodontal.

ABSTRACT: The teeth adjacent to the alveolar cleft, in patients with cleft lip and palate, present a higher incidence of periodontal problems, according to the literature. The purpose of this study was to evaluate whether the temporary teeth adjacent to the alveolar cleft present a higher incidence of periodontal problems in children with non-syndromic complete unilateral cleft lip and palate, born in 2010 and 2011, treated at the Hospital Nacional de Niños "Dr. Carlos Sáenz Herrera", Caja Costarricense de Seguro Social. This prospective, cross-sectional, descriptive, and interventional study evaluated epidemiological, clinical and radiographic variables (bacterial plaque, pocket depth, insertion level, gingival recession, bleeding, keratinized and inserted gingiva, dental calculus and mobility, type of alveolar cleft). It used descriptive statistical analysis techniques frequency distribution, crossing of variables and construction of confidence intervals. Data analysis and statistical processing was performed in SPSS version 17.0 and in Excel. The group consisted of 17 patients, with an average age of 5 years. 47 % dental plaque and 0 % dental calculus were found. Pocket depth and bleeding were statistically higher for teeth in the alveolar cleft. The teeth adjacent to the cleft had less keratinized and inserted gingiva. Regarding dental mobility, there is no statistically significant difference. Only one tooth had gingival recession. The complete alveolar cleft predominated radiographically. Teeth close to the alveolar cleft have a greater predisposition to periodontal problems, so regular monitoring of periodontal health is relevant.

Incidence of periodontal compromise in teeth indicated for undergoing endodontic treatment: A clinical study.

OBJECTIVE: The aim of this study was to evaluate the periodontal status of teeth indicated for undergoing endodontic treatment. MATERIALS AND METHODS: Two hundred and nine teeth were evaluated using probing depth tests at three vestibular and three palatine/lingual sites before the patients underwent treatment. Teeth that presented up to 3-mm probing depth were considered as healthy. Those that presented at least one site with probing depth >3 mm were considered periodontally compromised. The data were statistically analyzed by means of applying the Chi-square test, with a level of significance of 5%. RESULTS: Of the total of 209 teeth evaluated, 40 (19.10%) presented periodontal compromise. There was statistically significant difference related to the compromised teeth of patients of the female gender (22.80%) compared with teeth of patients of the male gender (12.30%) (P < 0.05). CONCLUSIONS: Fewer than 20% of the teeth evaluated presented a periodontal compromise. Patients of the female gender presented a higher number of periodontally compromised teeth than patients of the male gender.

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.

Prevalence and predictors for clinical attachment loss in adolescents in Latin America: cross-sectional study.

AIM: To describe the prevalence, severity and extension of clinical attachment loss (CAL) and to study the predictors in 15- to 19-year-old adolescents from high schools in the Latin America. MATERIALS AND METHODS: A cross-sectional, epidemiological study was performed. The sample included 1070 high school adolescents 15-19 years of age from Santiago de Chile (Chile), Buenos Aires, Córdoba, Mendoza (Argentina), Montevideo (Uruguay), Quito (Ecuador) and Medellín (Colombia). Calibrated examiners performed full mouth, six sites per tooth clinical examination. RESULTS: There was a response rate of 100%. The prevalence of CAL ≥3 mm in ≥1 site was 32.6%, probing pocket depth ≥4 mm was 59.3% and bleeding on probing (BoP) ≥25% was 28.6%. The logistic regression analysis adjusted for cities revealed that smoking (OR = 1.6), attending public school (OR = 2.3) and having a BoP ≥25% (OR = 4.2) were positively associated with CAL ≥3 mm in ≥ 1 site. CONCLUSION: Clinical attachment loss was prevalent in Latin America adolescents and it is associated with smoking, attendance public school and BoP.

Remodelação alveolar e perfil bacteriano em implantes instalados em diferentes níveis relacionados à crista óssea / Bone remodeling and bacterial profile in dental implants inserted in different levels in relation to the crestal bone

A substituição clínica de dentes naturais perdidos por implantes osteointegrados tem representado uma das primeiras opções terapêuticas para a reabilitação de pacientes total ou parcialmente edêntulos. Apesar dos excelentes índices de sucesso demonstrados pelas restaurações implanto-suportadas, alguns fatores permanecem não esclarecidos, principalmente no que diz respeito à remodelação óssea ao redor dos implantes osteointegrados. Desta forma, o objetivo deste estudo foi avaliar a relação do nível de instalação dos implantes dentários com os parâmetros clínicos, com a remodelação óssea peri-implantar e com a colonização bacteriana, em implantes de plataforma regular, submetidos à carga imediata. Implantes de plataforma regular foram instalados em dois diferentes níveis em relação à crista óssea – ao nível ósseo e supra ósseo (1 mm). No total, trinta e cinco implantes em 9 pacientes (idade média de 62,4 ± 11,2 anos) foram avaliados radiograficamente no momento da instalação dos implantes (T1) e 6 meses após (T2), momento no qual também foram feitas análises clínicas e coleta de amostras para o teste microbiológico. Nos exames radiográficos foram analisadas a perda óssea, a partir de mensurações lineares da distância entre um ponto fixo do componente protético e o ponto mais coronário do contato osso-implante, e a densidade óptica alveolar obtida a partir de regiões ósseas de interesse (ROIs). As análises clínicas consistiram na avaliação da profundidade de sondagem e na mensuração do volume do fluido gengival peri-implantar. O perfil bacteriano dos sítios avaliados foi caracterizado por meio do método de análise de checkerboard DNA-DNA hybridization. Os testes estatísticos realizados mostraram não haver relação entre o nível de instalação dos implantes em relação à crista óssea e a remodelação óssea alveolar, tanto com relação ...

The replacement of missing teeth with osteointegrated dental implants represents one of the first therapeutic options for the rehabilitation of totally or partially edentulous patients. In spite of clinical success rates for implant-supported restorations, some factors remain nuclear, especially those related to alveolar bone remodeling around osteointegrated implants. Thus, the aim of this study was to evaluate the relation between the installation level of dental implants with bone remodeling and bacterial colonization, in regular platform implants, under an immediate loading protocol. Dental implants with regular platform were inserted in different levels related to the bone crest – on the level of bone crest and above the bone crest. In total, thirty-five implants in 9 patients (mean age 62,4 ± 11,2 years) were radiographically evaluated in the moment of implant installation (T1) and 6 months after (T2), when clinical analysis and sample collecting for microbiologic test were performed. In radiographic exams were analyzed the marginal bone loss, from linear measurements of the distance between a fixed point of prosthetic components and the most coronal point of bone-implant contact, and optical alveolar density, from bone regions of interest (ROIs). Clinical analysis consisted of probing depth evaluation and peri-implant crevicular fluid volume mensuration. The bacterial profile of selected sites was characterized by checkerboard DNA-DNA hybridization method. Statistic tests showed no relation between implant insertion levels and alveolar bone remodeling, with relation to marginal bone loss (p = 0,725) and optical alveolar density (p = 0,975). It was not also possible to establish a correlation among alveolar ...

Este artículo analiza los determinantes más importantes del diagnóstico periodontal utilizados en la práctica clínica diaria.

The correct diagnosis of periodontal disease is a pre-requisite for an appropriate periodontal treatment. Periodontal disease is an infectious-inflammatory process that affects different clinical variables that must be analyzed before reaching the diagnosis. The diagnosis should be a carefully performed analysis of the clinical expression of the disease, from gingivitis to periodontitis. This article reviews the most important determinants of periodontal diagnosis.

Periodontal status in female psychiatric patients / Estado periodontal de pacientes psiquiátricas

Objective: To establish the periodontal status in female psychiatric patients from ®Nuestra Señora del Perpetuo Socorro¼ Mental Hospital at Pasto, Colombia in 2007. Methodology: We evaluated 59 patients and assessed Quigley-Hein and sulcus bleeding indexes, clinical attachment loss, probing depth, gingival enlargement, tooth displacement, and furcation involvement. Variables such as age, hospitalization, mental illness, other systemic condition and psychiatric medications were analyzed. Results: The Quigley-Hein Index was 3.05, SD=1.56, sulcus bleeding index on probing index was 3.08, SD=1.54. Of the women 49.2% had a clinical attachment loss (CAL) of 7 mm. There was an increasing percentage of CAL from 5 to 7 mm in patients with more than 10 years of hospitalization. Women with schizophrenia and mental retardation showed CAL from 2 to 7 mm. Patients who ingested antipsychotics-antiparkinsonians had CAL of 17 mm. Conclusions: Periodontal disease is severe in these patients and might be influenced by hospitalization, mental illness, and medication.
