RESUMO
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.

OBJECTIVES: This study aimed to evaluate the clinical effects of 0.05% sodium hypochlorite mouth rinse on supragingival biofilm and gingival inflammation. METHODS: The study was performed as a controlled, randomised, investigator-blinded, parallel group trial in 40 prison inmates. Following a preparatory period to obtain a plaque- and gingivitis-free dentition, tooth-brushing was substituted for 21 days by supervised twice daily rinsing with either 15 ml of fresh solution 0.05% sodium hypochlorite or 15 ml of distilled water. Clinical outcomes were assessed using the Quigley-Hein Plaque Index (QHPI), the Löe and Silness Gingival Index (L&SGI) and bleeding on probing. Adverse events were evaluated by questionnaire, visual examination and clinical photographs. RESULTS: At day 21, the average QHPI score had increased to 3.82 in the water rinse group and 1.98 in the sodium hypochlorite rinse group. The average L&SGI score had increased to 2.1 in the water rinse group and 1.0 in the sodium hypochlorite rinse group, and the average percentage of sites that bled on probing had increased to 93.1% in the water rinse group and 56.7% in the sodium hypochlorite rinse group. Differences were statistically significant (P = 0.001). A brown extrinsic tooth stain along the gingival margin appeared in 100% of participants in the sodium hypochlorite rinse group and in 35.0% of participants in the water rinse group (P < 0.05). CONCLUSIONS: An oral rinse with 0.05% sodium hypochlorite resulted in significant reductions in supragingival biofilm accumulation and gingival inflammation. Dilute sodium hypochlorite may represent an efficacious, safe and affordable antimicrobial agent in the prevention and treatment of periodontal disease.

In clinical trials, Spiramycin has shown additional benefit overscaling and root planing on pocket depth reduction, but its effect on periodontal microbiota was evaluated only by darkfield microscopy. Therefore, this study was conducted to determine the effect of Spiramycin administration on Porphyromonas gingivalis and other periodontopathic bacteria using 16S rARN PCR technique. Thirty two non-smoker adults with untreated periodontitis and pocket depth > or = 7 mm. were evaluated to participate in this randomized placebo-controlled clinical trial. Clinical measurements were performed on day -15, 15, 30 and 90 from baseline. Subgingival samples were analyzed for detection of Porphyromonas gingivalis (Pg), Tannerella forsythia (TJ), Treponema denticola (Td) and Aggregatibacter actinomycetemcomitans (Aa) on days -15, 30 and 90. On day 0, 25 Pg positive subjects were randomly assigned to receive either systemically administered Spiramycinfor 7 days (Test group SP) or identical placebo tablets (Placebo group PL). After Spiramycin administration Pg, Tf and Td were suppressed showingstatistically significant difference (p<0.05) with the Placebo group. None of the groups showed changes in Aa detection. These data indicate that bacteria currently associated with advanced periodontitis (Pg, Tf and Td) are suppressed after 7 days of systemic administration of Spiramycin.

The aim of this study was to conduct a retrospective assessment of the clinical results at 6,12 and 24 months of root coverage in single gingival recessions using coronally positioned flap and acellular dermal matrix allograft. Clinical records were collected from 16 patients with single gingival recessions who visited a private practice in Periodontics in 2005 and 2006. They were treated through a coronally positioned flap and acellular dermal matrix allograft. The following periodontal parameters were recorded at baseline, 6, 12 and 24 months: Recession Depth, Recession Width, Probing Depth, Clinical Attachment Level, Keratinized Tissue Width, Plaque Index, Gingival Index and Sensitivity. The percentage of root coverage was 91.18 ± 21.26 at 6 months, 90.18 ± 22.04 at 12 months and 90.83 ± 18.41 at 24 months. Complete root coverage was 81% (13 out of 16) at 6 and 12 months. At 24 months, complete root coverage was 75% (9 out of 12). The plaque and gingival indexes did not vary significantly between baseline and measurement times. Probing depth was maintained at healthy levels during the months of follow-up. Sensitivity decreased at 12 months (4 of 16) compared to baseline (14 of 16), and was maintained at 2 years (2 of 12). This retrospective study showed that acellular dermal matrix allograft could be considered a useful alternative for the treatment of single gingival recessions, reducing the discomfort and morbidity associated with the palatal donor site.
El objetivo de este trabajo fue evaluar retrospectivamente los resultados clínicos del recubrimiento radicular en recesiones únicas mediante el uso de colgajo desplazado coronal y matriz dérmica acelular a los 6,12 y 24 meses. Se recolectaron las historias clínicas de 16 pacientes que presentaban recesiones gingivales únicas, concurrentes a un consultorio privado de Periodoncia en los años 2005 y 2006. Fueron tratados utilizando colgajo desplazado coronal y matriz dérmica acelular. Previamente se registraron los siguientes parámetros periodontales: Altura de la recesión, Ancho de la recesión, Profundidad al sondaje, Nivel Clínico de inserción, Ancho del tejido queratinizado, Indice de placa, Indice gingival y Sensibilidad. Los datos se obtuvieron nuevamente a los 6, 12 y 24 meses. El porcentaje de recubrimiento radicular obtenido a los 6 meses fue de 91,18 ± 21,26, de 90,18 ± 22,04 a los 12 meses y 90,83 ± 18,41 a los 24 meses. La cobertura radicular completa fue de 81% (13 de 16) a los 6 y 12 meses, y fue de 75% a los 24 meses (9 de 12). Los índices de placa y gingival no variaron significativamente entre el inicio y los diferentes intervalos de tiempo. La profundidad al sondaje se mantuvo en niveles compatibles con salud durante los meses de seguimiento. Se logró disminuir la sensibilidad a los 12 meses (4 de 16) respecto al inicio del tratamiento (14 de 16), manteniendo dicha proporción a los 2 años (2 de 12). El presente estudio retrospectivo mostró que el uso de la matriz dérmica acelular podría ser considerado una alternativa predecible para el tratamiento de recesiones gingivales únicas, reduciendo el disconfort y la morbilidad asociada al sitio donante palatino.

BACKGROUND: The aim of this study was to evaluate the effect of suturing on the early wound healing of donor sites of subepithelial connective tissue grafts (SCTG), harvested by the single incision technique (SIT), following the application of a collagen sponge. METHODS: Thirty-six patients were randomized to receive a collagen sponge with or without sutures in the palatal donor sites following connective tissue grafting via the SIT. Outcome variables were early healing index (EHI) at 7, 14, and 30 days, self-reported pain using a visual analogue scale (VAS) recorded on the 0 to 100 scale at 7 and 14 days, and immediate and delayed bleeding. RESULTS: No significant differences were found between groups at baseline. EHI index showed no differences between groups in all-time intervals. Eight subjects from suture group (SG) and 10 from no suture group (nSG) showed complete wound closure at day 14 (P >0.05) and at 30 days, complete closure was observed in 35 out of 36 patients. Four subjects from the SG and three from the nSG had immediate bleeding (P >0.05), while delayed bleeding was observed in two subjects from the SG and three from the nSG during the first week of healing (P >0.05). No differences were found in VAS scale between groups (SG, 36.2 ± 24.8; nSG, 21.5 ± 24.2, P >0.05). CONCLUSION: It can be concluded that when a collagen sponge is placed in palatal donor areas of SCTG harvest by means of the SIT (incision length of ≈15 mm), sutured and non-sutured sites display similar early wound healing outcomes and patient-reported outcomes.

BACKGROUND: The social diversity, heterogeneous culture, and inherent economic inequality factors in Latin America (LA) justify conducting a comprehensive analysis on the current status and future trends of peri-implant diseases and conditions. Thus, the aim of this Delphi study was to predict the future trends in the diagnosis and treatment of peri-implant diseases and conditions in LA countries for the year 2030. METHODS: A Latin American steering committee and group of experts in implant dentistry validated a questionnaire including 64 questions divided into eight sections. The questionnaire was run twice with an interval of 45 days, with the results from the first round made available to all the participants in the second round. The results were expressed in percentages and data was analyzed describing the consensus level reached in each question. RESULTS: A total of 221 experts were invited to participate in the study and a total 214 (96.8%) completed the two rounds. Moderate (65%-85%) to high consensus (≥ 85%) was reached in 51 questions (79.69%), except in the questions dealing with "prevalence", where no consensus was reached. High and moderate consensus was attained for all the questions in three fields (risk factors and indicators, diagnosis and treatment of peri-implant conditions and deficiencies, and prevention and maintenance). CONCLUSIONS: The present study has provided relevant and useful information on the predictions in the diagnosis and treatment of peri-implant diseases with a high level of consensus among experts. Nevertheless, there is still a lack of agreement in certain domains.

Dental plaque removal and the understanding of risk factors, risk indicators and social determinants are important components in the prevention of periodontal disease. Periodontal diseases and dental caries are largely preventable conditions, but require a "common risk factor approach" with non-communicable diseases with the purpose of improving their prevention and control, and positive impact on health. The aim of this consensus was to identify the evidence and gaps in periodontal prevention in Latin American, and to propose individual and collective recommendations for the population, health professionals, dental practice and government. The prevention of periodontal diseases in Latin America has mainly been focused on oral hygiene instruction, use of toothbrushes and interproximal devices, but in some patients, it is necessary to use adjuncts to these measures, such as antimicrobial and/or probiotic products that are backed by broad scientific evidence. Some evidence has shown that there are inadequate knowledge, attitudes and practices among patients, dentist and other health professionals. The prevention of periodontal diseases and caries should be adopted as a healthy lifestyle routine, because of their local and systemic effects. Recently, new empowerment strategies have been proposed in order to generate behavioral changes. Periodontal diseases can often be prevented, or controlled by joined efforts between government health systems, scientific associations, universities, health professionals, private companies and communities. In conclusion, the relations between periodontal diseases, caries, healthy lifestyles and NCD's offer an ideal opportunity to change Latin American prevention strategies at both the individual level and population levels.

The aim of this study was to evaluate changes in periodontal status and maxillary buccal bone by considering clinical and tomographic parameters during the first year of orthodontic expansion with Invisalign® aligners. Upper first (1PM) and upper second (2PM) premolars of 19 patients with orthodontic expansion requirement treated with Invisalign® aligners were evaluated. Plaque index (PI), gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL) and cone beam tomographic (CBCT) records were collected at 76 sites before starting treatment (T0) and at 12 months (T1). Bone height was measured from cementoenamel junction (CEJ) to the crest cortical bone (CC). Bone thickness was measured at two levels: 4 mm (CEJ+4) and 6 mm (CEJ+6) apical to the CEJ. A descriptive analysis was made of the variations of bone thickness and height in a series of cases. The average expansion was 1.93 mm for 1PM and 167 mm for 2PM. Arithmetic mean of distance CEJ-CC in 1PM was 3.05 mm at T0, and remained at 3.05 mm at T1. Arithmetic mean of distance CEJ-CC in 2PM was 2.06 mm at T0 and 2.31 at T1. Post-expansion, most of the analyzed sites (86%) exhibited a bone thickness of ≥0.5 mm. The greatest variations between T0 and T1 were observed at the level of 1PM CEJ+ 4 and 2PM CEJ+ 6. The minimal changes in the clinical records (GI, PI, PPD and CAL) between T0 and T1 were compatible with the maintenance of gingivalperiodontal health. Invisalign® for expansion movements did not produce substantial changes in the evaluated periodontal clinical parameters or in the bone measurements. Removable appliances reduce plaque retentive factors and favor adequate oral hygiene.
El objetivo de este estudio fue evaluar los cambios en el estado periodontal y hueso facial maxilar a través de parámetros clínicos y tomográficos durante la expansión ortodóncica con alineadores Invisalign® en el primer año de tratamiento. Se evaluaron los primeros (1PM) y segundos (2PM) premolares superiores pertenecientes a 19 pacientes con requerimiento de expansión ortodóncica tratados con alineadores Invisalign®. Se registraron los índices de placa (IP), índice gingival (IG), profundidad al sondaje (PS) y nivel de inserción (NI) y registros tomográficos de haz cónico (CBCT) en 76 sitios antes de comenzar el tratamiento (T0) y a los 12 meses (T1). Se midió la altura ósea desde el límite amelocementario (LAC) hasta la cortical de la cresta (CC) y el espesor en dos niveles; a 4 mm (LAC+4) y a 6 mm (LAC+6) hacia apical del LAC. Se realizó un análisis descriptivo de las variaciones de la altura y espesor óseo en una serie de casos. La expansión promedio para 1PM fue de 1,93 mm y para 2PM fue de 1,67 mm. La media aritmética de LAC-CC en primeros premolares fue de 3,05 mm en T0 y se mantuvo el valor de 3,05 mm en T1. La media aritmética de LAC-CC en segundos premolares fue de 2,06 mm en T0 y 2,31 en T1. Post expansión, la mayoría de los sitios (86%) analizados exhibieron un espesor óseo ≥0,5 mm. Las mayores variaciones entre T0 y T1 se observaron a nivel de 1PM CEJ+4 y 2PM CEJ+6. Los registros clínicos (PI, GI, PPD y CAL) evidenciaron mínimos cambios entre T0 y T1, compatibles con el mantenimiento de la salud gíngivo-periodontal. El uso de Invisalign ® para movimientos de expansión no produjo cambios sustanciales en los parámetros clínicos periodontales evaluados ni en las mediciones óseas. La aparatología removible reduce los factores retentivos de placa bacteriana y facilita una adecuada higiene oral.

Periodontal diseases are considered a worldwide public health problem, owing to their high prevalence in developed and developing countries. Periodontitis may lead to tooth loss, which can impact oral health-related quality of life. Gingivitis and periodontitis have been extensively studied regarding their etiopathogenesis, epidemiology, prevention and treatment outcomes. However, most of these aspects are studied and discussed globally, which may hamper a clear interpretation of the findings and the design of effective plans of action for specific regions or populations. For example, in Latin America, epidemiological data about the distribution of periodontal diseases is still scarce, mainly when it comes to nationwide representative samples. This Consensus aimed to address the following topics related to periodontal diseases in Latin America: a) The impact of the global burden of periodontal diseases on health: a global reality; b) Periodontal diseases in Latin America; c) Strategies for the prevention of periodontal diseases in Latin America; d) Problems associated with diagnosis of periodontal conditions and possible solutions for Latin America; e) Treatment of Periodontitis. This consensus will help to increase awareness about diagnosis, prevention and treatment of periodontal diseases, in the context of Latin American countries.

INTRODUCTION: There is limited evidence related to the long-term treatment outcomes of acellular dermal matrix graft (ADMG) plus coronally advanced flap (CAF) for the treatment of multiple recession defects. The aim of this case report is to assess the short- and long-term clinical outcomes of Miller Class I multiple gingival recession-type defects in the maxilla treated with ADMG plus CAF. CASE PRESENTATION: A 36-year-old female patient smoking < five cigarettes per day presented multiple adjacent Miller Class I gingival recession in the left maxilla and was referred for treatment with chief complaints of dental hypersensitivity and esthetics. Root coverage was achieved by ADMG + CAF and the patient underwent a 10-year follow-up. CONCLUSIONS: Within the limits of this case report, mean root coverage obtained at 6 months could not be maintained in the long term. A significant relapse was detected after 10 years, from 80% complete root coverage (CRC) at 6 months to 40% at 10 years. Monitoring, compliance, and reinstructions in oral hygiene techniques seem mandatory for minimizing relapse of gingival recessions after root coverage procedures.

The aim of this study was to investigate the impact of smoking on gingival inflammation in a representative sample of 1,650 adults from Santiago (Chile), Porto Alegre (Brazil), and Tucumán (Argentina). A questionnaire was administered to participants to gather demographic and behavioral characteristics, including smoking habits. The participants were clinically examined to obtain gingival index (GI), gingival bleeding index (GBI), visible plaque index (VPI), and calculus presence values. Gingival inflammation was defined as a mean GI > 0.5. Heavy smokers presented significantly lower levels of gingival inflammation, as reflected by both GI and GBI, than both light and moderate smokers, despite their having increased amounts of plaque and calculus. Being 50 years old or older [odds ratio (OR), 1.93], a VPI ≥ 30% (OR, 28.1), and self-reported diabetes (OR, 2.79) were positively associated with detection of gingival inflammation. In conclusion, the occurrence of clinically detectable gingival inflammation was lower in heavy smokers than light and moderate smokers. Older age, diabetes, and visible plaque emerged as risk indicators of gingivitis. Plaque and gingival indices are significantly associated regardless of the smoking status.

Resumen Los fracasos y complicaciones en el campo de la cirugía bucal son analizados generalmente desde un punto de vista técnico o biológico. En términos generales, a partir del espíritu fragmentario del conocimiento, se tiende a enfocar la atención odontológica en la parte técnica y teórica. Actualmente se están produciendo cambios socioculturales que están generando modificaciones en los paradigmas de la atención odontológica, considerando también la comunicación con el paciente y la situación psicológica tanto del paciente como del equipo profesional. En este editorial se busca reflexionar sobre estos temas analizando perspectivas más integradas para lograr un mayor equilibrio en la atención profesional.
Abstract Failures and complications in the field of oral surgery are generally analyzed from a technical or biological point of view. In general terms, based on the fragmentary spirit of knowledge, dental care tends to be focused on the technical and theoretical knowledge. We are currently witnessing sociocultural changes that are producing modifications in the paradigms of dental care, also considering communication with the patient and the psychological situation of both the patient and the professional team. This editorial seeks to reflect on these issues, considering the most integrated visions to achieve greater balance in professional care.

El propósito de este reporte es describir el tratamiento no quirúrgico y quirúrgico en una paciente con múltiples implantes con peri-implantitis. Inflamación, sangrado espontáneo, supuración y pérdida ósea fueron los signos clínicos y radiográficos observados en los 21 implantes presentes en su boca. Las profundidades al sondaje oscilaban entre 5 y 15 mm. Se llevó a cabo la terapia no quirúrgica asociada a antibióticos sistémicos (Metronidazol 500 mg) y antiséptico (Clorhexidina 0,12%) con la finalidad de reducir los signos de inflamación y sangrado. Durante la re-evaluación se colocaron gránulos de Minociclina de liberación controlada en las bolsas residuales. Los sitios que no respondieron fueron abordados quirúrgicamente, realizando además la implantoplastia de las espiras que quedaron expuestas al medio bucal. Uno de los implantes debió ser explantado. A los 9 meses, no presentaba signos de inflamación peri-implantar, sangrado al sondaje ni pérdida ósea progresiva.
The aim of this report is to describe the non-surgical and surgical treatment of a patient with multiple implants with peri-implantitis. Inflammation, spontaneous bleeding, suppuration and bone loss were the clinical and radiographic signs observed in the 21 implants present in her mouth. Probing depths ranged from 5 to 15 mm. Non-surgical therapy with systemic antibiotics (Metronidazole 500 mg) and antiseptic (Chlorhexidine 0.12%) was carried out in order to reduce the signs of inflammation and bleeding. During re-evaluation, controlled-release minocycline granules were placed in the residual pockets. The sites that did not respond were approached surgically. Also, the implantoplasty of the threads that were exposed to the oral environment was performed. One of the implants had to be explanted. At 9 months, there were no signs of peri-implant inflammation, bleeding on probing or progressive bone loss.

The aims of this study were to describe the self-reported oral hygiene habits, dental visit frequency, and gingival bleeding perception in adult populations from three South American cities, and also to assess the association of these variables with sociodemographic data and with the clinical presence of plaque and gingival inflammation. Five-hundred and fifty adult subjects from each city (Porto Alegre, Brazil; Tucumán, Argentina; Santiago, Chile) received full mouth examinations to determine visible plaque and gingival index. A structured questionnaire on demographics, habits, attitudes and knowledge of oral health was also administered. The data were analyzed according to dental visit frequency, toothbrushing frequency, interproximal tooth cleaning frequency, subjects' perception of gum bleeding, and proportion of subject sites with VP and bleeding sites. Analysis of the association among the variables was performed using either a chi-square test or Fischer's exact test. Toothbrushing twice a day or more was reported by 84.2% of the subjects, but only 17.7% reported daily interdental cleaning, and 60.2% reported visiting a dental clinic only in an emergency. Only 2.97% had no bleeding sites, whereas 33.7% had 50% or more bleeding sites. Regular interdental self-cleaning and a dental visit every 3-6 months was associated with less plaque and less gingival bleeding. More than 12 years of education was associated with healthier habits, less bleeding and plaque scores. In conclusion, the oral health behavior of South American adult subjects from these cities is below the international recommendations, especially in relation to interdental cleaning and regular dental visits.

The aim of the present study was to assess the periodontal treatment needs of the population that spontaneously sought treatment from general dentists. 3694 patients (2000 females and 1494 males, age range between 18 and 84 years) were evaluated using the Community Periodontal Index (CPI). Data were reported according to the percentage of subjects with the highest Score: 14.3% presented pocket depth > or = 5.5 mm (Score 4), 26.4% pocket depth between 3.5 and 5.5 (Score 3), 38.3% presented pockets < or = 3.5 mm with calculus or overhanging restorations (Score 2), 17.2% pockets < or = 3.5 mm with bleeding upon probing without calculus (Score 1) and 3.2% were healthy (Score 0). Analyzing the data according to age it was observed that in the group > 40 years the percentage of patients with Score 4 was higher (25.1%) compared to the other two groups of 18-34 years (6.4%) and 34-45 years (14.3%). Only 16.4% of the patients consulted for periodontal reasons (gingival bleeding or tooth mobility), whereas 88% requested treatment for other reasons (pain, caries, esthetics, replacement of teeth, etc.). However 77% of the patients in this last group needed periodontal treatment. 96.8% of the patients attending the general dentistry office needed periodontal treatment: 17.2% oral hygiene instruction, 65.2% oral hygiene instruction and scaling and 14.3% complex treatment.

Fueron tratados utilizando colgajo desplazado coronal y matriz dérmica acelular. Previamente se registraron los siguientes parámetros periodontales: Altura de la recesión, Ancho de la recesión, Profundidad al sondaje, Nivel Clínico de inserción, Ancho del tejido queratinizado, Indice de placa, Indice gingival y Sensibilidad. Los datos se obtuvieron nuevamente a los 6, 12 y 24 meses. El porcentaje de recubrimiento radicular obtenido a los 6 meses fue de 91,18 ± 21,26, de 90,18 ± 22,04 a los 12 meses y 90,83 ± 18,41 a los 24 meses. La cobertura radicular completa fue de 81% (13 de 16) a los 6 y 12 meses, y fue de 75% a los 24 meses (9 de 12). Los índices de placa y gingival no variaron significativamente entre el inicio y los diferentes intervalos de tiempo. La profundidad al sondaje se mantuvo en niveles compatibles con salud durante los meses de seguimiento. Se logró disminuir la sensibilidad a los 12 meses (4 de 16) respecto al inicio del tratamiento (14 de 16), manteniendo dicha proporción a los 2 años (2 de 12). El presente estudio retrospectivo mostró que el uso de la matriz dérmica acelular podría ser considerado una alternativa predecible para el tratamiento de recesiones gingivales únicas, reduciendo el disconfort y la morbilidad asociada al sitio donante palatino.
RESUMO
OBJECTIVES:: The aim of this study is to investigate the prevalence and severity of gingival inflammation and associated risk indicators in South American adults. MATERIAL AND METHODS:: Multi-stage samples totaling 1,650 adults from Porto Alegre (Brazil), Tucumán (Argentina), and Santiago (Chile) were assessed. The sampling procedure consisted of a 4-stage process. Examinations were performed in mobile dental units by calibrated examiners. A multivariable logistic regression model was utilized for associating variables as indicators of gingival inflammation (GI) (Gingival Index ≥0.5). Statistical significance was set at 0.05. RESULTS:: A total of 96.5% of the adults have GI. Regarding the severity of GI, 22.5% of participants examined have mild GI, 74.0% have moderate GI, and 3.6% have severe GI. The multivariate analyses identify the main risk indicators for GI as adults with higher mean of Calculus Index (OR=18.59); with a Visible Plaque Index ≥30% (OR=14.56); living in Santiago (OR=7.17); having ≤12 years of schooling (OR=2.18), and females (OR=1.93). CONCLUSIONS:: This study shows a high prevalence and severity of gingival inflammation, being the first one performed in adult populations in three cities of South America.

Objetivo: Presentar la respuesta clínica a largo plazo del tratamiento de un granuloma periférico de células gigantes en un implante oseointegrado en el maxilar inferior. Caso clínico: Un paciente de 60 años, de sexo masculino, sin antecedentes sistémicos, concurrió por una lesión con márgenes definidos, de color rojizo morado y consistencia blanda sobre los tejidos blandos en la cara vestibular de un implante colocado en zona de 46. Se realizó la escisión quirúrgica de la lesión, se procesó el tejido extirpado y se envió al laboratorio. El estudio anatomopatológico confirmó el diagnóstico de granuloma periférico de células gigantes. La lesión recidivó dos veces. En la tercera extirpación se realizó la implantoplastía de la superficie del implante. La cicatrización no presentó inconvenientes. Hasta el último control, a los 5 años, no volvió a haber recidiva. Conclusión: En este caso clínico, se logró mantener la salud periimplantaria durante 5 años luego de la eliminación de un granuloma periférico de células gigantes. No obstante, este tuvo que ser removido en tres oportunidades debido a la alta recidiva (AU)
Aim: To evaluate the long-term clinical response to the treatment of a peripheral giant cell granuloma in an osseointegrated implant in the lower jaw. Clinical case: A 60-year-old male patient, with no systemic medical problems, presented a soft tissue lesion located at the buccal aspect of an implant placed in the 46 area. The lesion had defined reddish-purple margins and soft consistency. Surgical excision of the lesion was performed, processed and sent to the laboratory. The histopathology confirmed the diagnosis of peripheral giant cell granuloma. The lesion recurred twice. During the third surgical removal an mplantoplasty of the implant surface was performed. The healing was uneventful and there was no recurrence until the last control at 5 years. Conclusion: In this clinical case, perimplantar gingival health was maintained for 5 years after the surgical removal of a giant cell peripheral granuloma. However, it had to be removed three times, demonstrating a high recurrence (AU)

The aim of this study was to evaluate clinical and microbiological effects of subgingival minocycline microgranules when used as an adjunct to scaling and root planing in subjects with Chronic periodontitis. Twenty-six non-smoker volunteers participated in the study. Four opposite sites, clinically standardized, with bleeding on probing (BOP) and pocket depth (PD) ≥ 6 mm were selected. Baseline BOP, PD and Clinical attachment level (CAL) were measured and microbiological samples were collected from the study sites and analyzed using PCR. Porphyromonas gingivalis (Pg) Tannerella forsythia (Tf), Treponema denticola (Td) and Aggregatibacter actinomycetemcomitans (Aa) were detected. One side of the mouth was randomly allocated to the experimental treatment: scaling and root planing plus minocycline microgranules (Test group=T) and the other side of the mouth to scaling and root planing alone (Control group=C). At days 30 and 90, clinical and microbiological examination was repeated. After 30 days BOP was reduced to 81% in C and to 12% in T and at day 90 to 58% in C and to 8% in T (p<0.05). PD was significantly reduced in both groups (C: 4.8mm, T: 4.2mm) favoring T at days 30 and 90 (p<0.05). CAL reduction at day 30 showed no difference between groups. At day 90, CAL reduction was higher in T (p<0.05). At days 30 and 90 Pg, Tf, Td and Aa was reduced in both groups. Pg reduction was significantly greater in group T. At day 90 frequency of sites with Td decreased in T and increased in C (p<0.05). No adverse effect was observed. This study showed that minocycline microgranules adjunct to scaling and root planing resulted in grater reduction of BOP and PD, higher CAL gain, increased probability of Pg suppression and retarded recolonization of Td than root instrumentation alone.
