Oral health status after orthodontic treatment: a retrospective study / Estado de salud bucal después del tratamiento de ortodoncia: un estudio retrospectivo

ABSTRACT: Orthodontic appliances in the oral cavity may cause problems such as white spot lesions, dental plaque, periodontal disease and root resorption. The aim of this study was to investigate the association between orthodontic treatment and oral health parameters including visible dental plaque, gingival recession and white spot lesions (WSLs). A total of 170 patients (86 females, 84 males) were randomly selected to determine visible dental plaque, gingival recession and white spot lesions by using pre-treatment and post-treatment oral photographs. Except of previously extracted teeth, maxillary and mandibular incisors, canine, 1st and 2nd premolars and 1st molar were evaluated. There was a significant difference between the T0 (before treatment) and T1 (after treatment) groups in visible plaque (P< 0.001). The distribution of gingival recession frequencies according to Miller classification before treatment did not differ from the after treatment (P=082). A statistically significant increase in the severity of WSL was detected between the two time points (P< 0.001). Males have been shown to have higher WSL incidence after treatment. In conclusion, the present study showed that visible dental plaque and white spot lesions significant increase after orthodontic treatment. Considering the relationship between oral health and orthodontic treatment, clinicians and patients should know the risks and take precautions.

RESUMEN: Los aparatos de ortodoncia en la cavidad oral puede causar problemas como lesiones de mancha blanca, placa dental, enfermedad periodontal y reabsorción radicular. El objetivo de este estudio fue investigar la asociación entre el tratamiento de ortodoncia y los parámetros de salud bucal, incluida la placa dental visible, la recesión gingival y las lesiones de mancha blanca (LMB). Un total de 170 pacientes (86 mujeres, 84 hombres) fueron seleccionados al azar para determinar la placa dental visible, la recesión gingival y las lesiones de manchas blancas mediante el uso de fotografías orales antes y después del tratamiento. Excepto los dientes extraídos previamente, se evaluaron incisivos maxilares y mandibulares, caninos, premolares y primeros molares. Hubo una diferencia significativa entre los grupos T0 (antes del tratamiento) y T1 (después del tratamiento) en la placa visible (P<0.001). La distribución de las frecuencias de recesión gingival según la clasificación de Miller antes del tratamiento no mostraron diferencias significativas con respecto al postratamiento (P=0.082). Se detectó un aumento estadísticamente significativo en la gravedad de LMB entre los dos puntos de tiempo (P<0.001). Se ha demostrado que los hombres tienen una mayor incidencia de LMB después del tratamiento. En conclusión, el presente estudio mostró que la placa dental visible y las lesiones de manchas blancas aumentaron significativamente durante el tratamiento de ortodoncia. Teniendo en cuenta la relación entre la salud bucal y el tratamiento de ortodoncia, los médicos y los pacientes deben conocer los riesgos y tomar precauciones.

The SmoCar Study: A Caribbean-Based Multicenter Study on the Prevalence and Disparities Linked to Smoking and Gingival Health.

The aim of the SmoCar (Smoking in the Caribbean) study was to estimate the prevalence of smoking and the disparities in the smoking practices of three regions in the Caribbean: Jamaica, Dominican Republic, and Puerto Rico. The secondary objective was to assess the prevalence and severity of gingivitis in relation to the smoking practices. The study population comprised 1,847 (weighted N = 1,830) individuals (18 years and older) who were volunteer participants from the capitals of Jamaica, Dominican Republic, and Puerto Rico. A structured interview was used to assess the participants' smoking behaviors. The gingival index was used to determine the extent of gingival inflammation. Polytomous regression was used to estimate the adjusted odds ratios (aORs) for smoking status (current, past, or never), according to risk factors (sex, age-group, education, marital status, tooth-brushing frequency, and city of residence). Logistic regression models were used to assess the associations between different smoking status variables and mild to moderate/severe gingivitis. The majority of the participants were never-smokers, with current smokers being found most commonly in Kingston (33.22%), followed by San Juan (12.76%) and Santo Domingo (8.8%). Both current (aOR = 2.22, 95% confidence interval [1.45, 3.40]) and past (aOR = 1.87, 95% confidence interval [1.19, 2.93]) smoking (vs. never smoking) was strongly associated with severe gingivitis. Smoking was the most prevalent in Jamaicans and the least prevalent in Dominicans. The study population of current smokers was found to have a fourfold increased risk of severe gingivitis and a twofold increased risk of moderate gingivitis.

Efecto antibacteriano de una pasta dental con xilitol sobre Streptococcus mutans en saliva de gestantes / Antibacterial effect of a toothpaste with xylitol on Streptococcus mutans in pregnant women's saliva

RESUMEN Introducción: Durante la gestación, algunos cambios fisiológicos en la mujer propician un incremento de la placa dental y de la microbiota cariogénica. Esta condición unida a una modificación de la dieta y a una inadecuada higiene bucal condicionarían desfavorablemente la salud oral tanto de la madre como del bebé. Objetivo: Determinar el efecto antibacteriano de una pasta dental con xilitol sobre el recuento de Streptococcus mutans en saliva de gestantes. Métodos: Ensayo clínico, a doble ciego, que se realizó en el Centro de Salud "José Olaya" (Chiclayo Perú), en enero de 2017. Se trabajó con una población muestral de 50 gestantes en el segundo trimestre que cumplieron con los criterios establecidos. Se crearon dos grupos: 25 gestantes usaron dentífrico con 10 por ciento de xilitol y 25 gestantes usaron dentífrico sin xilitol. Se les tomó y proceso microbiológicamente una muestra de saliva antes del inicio del estudio y 14 días después del uso de las respectivas pastas. Se realizó el recuento de unidades formadoras de colonias de Streptococcus mutans en saliva con una confiabilidad altamente significativa mediante el coeficiente de correlación intraclase, calibración intra e interexaminador (1,000 y 0,999, respectivamente). El análisis de los datos se realizó mediante la prueba U de Mann-Whitney, considerando un nivel de significancia del 5 por ciento. Resultados: No se encontró diferencia significativa entre las gestantes que emplearon pasta dental con xilitol en comparación con las que utilizaron pasta dental sin xilitol (p= 0,062). Conclusiones: El efecto antibacteriano de la pasta dental comercial con xilitol es similar a una pasta dental sin xilitol sobre el recuento de Streptococcus mutans en saliva de gestantes(AU)

ABSTRACT Introduction: Some physiological changes occur in women during pregnancy which cause an increase in dental plaque and cariogenic microbiota. This situation, alongside a modification in the diet and inadequate oral hygiene, negatively affect the oral health of both the mother and the baby. Objective: Determine the antibacterial effect of a toothpaste with xylitol on the count of Streptococcus mutans in pregnant women's saliva. Methods: A double-blind clinical trial was conducted in José Olaya Health Center (Chiclayo, Peru) in January 2017. The sample population was 50 women in the second trimester of pregnancy who met the established inclusion criteria. Two groups were formed: 25 pregnant women used a toothpaste with 10 percent xylitol and the other 25 used a toothpaste without xylitol. A saliva sample was taken and processed microbiologically before the start of the study and 14 days after use of the two toothpastes. A count was performed of colony-forming units for Streptococcus mutans in saliva with highly significant reliability, using the intraclass correlation coefficient, and intra- and inter-rater calibration (1.000 and 0.999, respectively). Data analysis was based on the Mann-Whitney U Test, with a significance level of 5 percent. Results: No significant difference was found between the pregnant women who used the toothpaste with xylitol and those who used the toothpaste without xylitol (p= 0.062). Conclusions: The antibacterial effect of the commercial toothpaste with xylitol is similar to that of a toothpaste without xylitol in terms of the Streptococcus mutans count in pregnant women's saliva(AU)

Condiciones de salud oral, higiene oral y estado nutricional en niños que acuden a un establecimiento de salud de la Región Huánuco, Perú / Oral health and oral hygiene conditions and nutritional status in children attending a health facility in the Huánuco Region, Peru

RESUMEN Con el objetivo de determinar la asociación entre las condiciones de salud oral e higiene oral y el estado nutricional en niños usuarios de un establecimiento de salud en la región Huánuco se realizó un estudio transversal descriptivo en 118 niños que acudieron al control de crecimiento y desarrollo (CRED) del Puesto de Salud «La Esperanza¼. Las condiciones de salud e higiene oral fueron evaluados mediante los índices de placa bacteriana visible, higiene bucal simplificado, hemorragia simplificado e inflamación gingival. El estado nutricional se obtuvo del último control de CRED registrado en la historia clínica. La desnutrición aguda (DA) fue el estado nutricional más frecuente. Entre los niños con DA la proporción de inflamación gingival severa fue 60,3%, sangrado de encías 61,5%, presencia de placa dentobacteriana 59,3% e higiene oral deficiente 60,3%. Se evidencia una mayor afectación de la salud oral e higiene oral en niños con desnutrición, principalmente aguda.

ABSTRACT In order to determine the association between oral health and oral hygiene conditions and nutritional status in children using a health facility in the Huánuco region, a cross-sectional descriptive study was conducted in 118 children who attended the Growth and Development Control (CRED) of the health clinic "La Esperanza." Oral health and hygiene conditions were evaluated by visible bacterial plaque, simplified oral hygiene, simplified bleeding, and gingival inflammation indices. Nutritional status was obtained from the last CRED control recorded in the clinical history. Acute malnutrition (AM) was the most common nutritional status. Among children with AM, the proportion of severe gingival inflammation was 60.3%; gum bleeding, 61.5%; dentobacterial plaque presence, 59.3%; and poor oral hygiene, 60.3%. There is evidence of a greater impact of oral health and oral hygiene on children with malnutrition, mainly acute.

Modelo operativo de promoción de la salud y prevención de enfermedades bucales en preescolares de Cuautla, Morelos-México / Operational model of health promotion and prevention of oral diseases in preschool children in Cuautla, Morelos-Mexico

Las estrategias tradicionales para abordar la salud bucal en México han carecido de un enfoque integrado a la promoción de la salud y a los factores de riesgo en común con otras patologías, principalmente crónicas. De unir esfuerzos se aprovecharían mejor los limitados recursos sanitarios. Esta investigación tuvo como objetivo implementar un modelo operativo de promoción de la salud y prevención de las enfermedades bucales, usando un ciclo de mejora continua en el preescolar de la comunidad Peña-Flores, Cuautla, Morelos. Se realizó un estudio cuasi-experimental con 120 niños de ambos sexos. La implementación contempló: diagnóstico epidemiológico bucal y social, capacitación de actores clave, ejecución del programa de salud bucal, monitoreo, análisis y evaluación de resultados. Se levantaron datos mediante una guía de observación participante, de reuniones con madres de familia y maestras bajo la perspectiva participativa del triple diagnóstico de educación popular. Se determinó el índice de dientes cariados, a extraer y obturados. Se realizó la medición de la placa dento-bacteriana utilizando el índice de sedimento dental (DIS). Como resultado del control y sistematización del proceso de cepillado dental y del monitoreo de la placa dento-bacteriana, se identificó una disminución del DIS de 1,04 a 0,47. Con la implementación de un menú escolar, se mejoró la alimentación infantil. El modelo implementado constituye una posible solución a la problemática de salud bucal del preescolar de la comunidad Peña-Flores, situado en un contexto de desventaja social por factores como pobreza, migración y déficit de servicios públicos(AU)

Access to oral health in early childhood in the city of Porto Alegre, Brazil. / Acesso à saúde bucal na primeira infância no município de Porto Alegre, Brasil.

The goal was to assess the access and factors connected to dental visits in children up to age five in the city of Porto Alegre, Brazil. The cross-sectional study was conducted in 10 Basic Health Units through a questionnaire and clinical examination on 560 children. Clinical (visible plaque, gingival bleeding and defs), socio-demographic, and visit access variables were assessed. Poisson Regression was used to calculate the Prevalence Ratios (PR), with a 95% confidence interval. Results showed that 68.2% of children had never gone to a dentist. The main reason reported for not visiting a dentist was not feeling the need (48.7%) and difficult access to a health clinic (15.8%). The purpose of going to the dentist was for prevention/revision (55.8%), and the most sought-after places for visits were the private office (43.9%) and health clinic (39.5%). The final multivariate model showed that age of the child (95%CI, PR = 1.03 (1.02-1.05)), household income (PR = 1.05; (1.01-1.08)), and the mother having completed high school (PR = 1.69 (1.15-2.56)) were associated with seeking dental consultation. Thus, it is crucial to recognize the importance of the family setting during the first years of life.

O objetivo foi avaliar o acesso e fatores associados à consulta odontológica em crianças de até 5 anos no município de Porto Alegre, Brasil. Estudo transversal realizado em 10 Unidades Básicas de Saúde, através de questionário e exame clínico em 560 crianças. Foram avaliadas variáveis clínicas (placa visível, sangramento gengival e ceo-s), sociodemográficas, e de acesso à consulta. Regressão de Poisson foi utilizada para cálculo de Razões de Prevalência (RP), com intervalo de confiança de 95%. Os resultados mostraram que 68,2% das crianças nunca haviam ido ao dentista. O principal motivo relatado para a não realização de consulta odontológica foi não ter sentido necessidade (48,7%) e dificuldade de acesso ao posto de saúde (15,8%). A procura pelo dentista teve como propósito a prevenção/revisão (55,8%) e os locais mais procurados para consultas foi o consultório particular (43,9%) e o posto de saúde (39,5%). O modelo multivariado final mostrou que a idade da criança (IC95%, RP = 1,03 (1,02-1,05)), a renda familiar (RP = 1,05; (1,01-1,08)) e a mãe ter concluído o ensino médio (RP = 1,69 (1,15-2,56)) estiveram associados com a procura por consulta odontológica. Assim, torna-se fundamental reconhecer a importância do contexto familiar durante os primeiros anos de vida.

Predictors of dental plaque and gingivitis in patients receiving integrated dental treatment-a longitudinal retrospective study.

OBJECTIVES: The identification of predictors of supragingival biofilm accumulation may improve the results of therapeutic strategies for dental caries and periodontal diseases in general clinical practice. This study aimed to determine predictors of changes in visible plaque (VP) and gingival bleeding (GB) during integrated dental care. MATERIALS AND METHODS: A retrospective longitudinal study was conducted by a census of patients receiving integrated dental care in a general clinical practice ambulatory at the Federal University of Rio Grande do Sul (Brazil). The sample comprised 91 charts of patients attended over a 6-months period. Gender, age, patient's main complaint, oral hygiene pattern, and clinical data were recorded from charts for the last two dental visits in the ambulatory. Changes in VP and GB were modeled by multiple linear regression and beta coefficients (b) were reported. RESULTS: The mean follow-up time was 13 months. Significant reductions in VP (32.8 ± 27.9 to 17.4 ± 19.4%; p < 0.001) and GB (27.1 ± 23.8 to 18.5 ± 17.3%; p < 0.001) were observed. Higher plaque reductions were predicted by higher baseline VP levels (p = 0.02), shorter time (< 12 months) elapsed between VP recordings (b = 14.1%, p = 0.02), interproximal cleansing (b = 11.9%, p = 0.03), lower number of sessions for oral hygiene instruction (b = 13.7%, p = 0.02), and presence of pockets ≥ 6 mm (b = - 12.4%, p = 0.02). GB was predicted by time of follow-up > 12 months and baseline VP. CONCLUSIONS: Plaque and gingivitis improved in patients under integrated dental care. Factors related to motivation, oral hygiene practices, and baseline periodontal status might be used as predictors of VP and GB changes. CLINICAL RELEVANCE: Visible plaque and gingivitis reduced in a sample of patients treated under integrated dental care. Some predictors may determine for which patients the treatment may be maximize and those who will need greater efforts to achieve the therapeutic goal for oral hygiene.

Antagonism of Bacteria from Dog Dental Plaque against Human Cariogenic Bacteria.

Dental caries are a process of demineralization and destruction of human teeth. They originate through many factors and are associated with biofilm formation, which consists of bacteria adhered to the teeth that form a structurally and functionally organized mass called dental plaque. Both the presence of Streptococcus mutans and the frequent consumption of sucrose correlate with a higher prevalence of caries in humans. In dogs, however, the incidence of this disease is low, due to factors such as differences in dental microbiota and/or their low consumption of sucrose. This work evaluated the antagonism of bacteria from dog's dental plaque against S. mutans, for the identification of producing strains of biotechnological products for use in preventing caries. This study used 95 bacterial isolates of canine dental plaque from the Veterinary Department at the Federal University of Viçosa, Minas Gerais, Brazil. A spot-on-the-lawn method was performed using Brain Heart Infusion agar with catalase for an initial identification of the antagonistic activity. Additional tests were conducted on the isolates classified as antagonists for confirmation of the activity, using modified Mann-Rogosa-Sharpe medium containing low dextrose concentration. These isolates were incubated at 37°C for 24 hours in anaerobiosis. The peptide nature of inhibition was evaluated using the following proteinases: proteinase K from Tritirachium album, bovine pancreatic trypsin, and type XII-A α-amylase from Bacillus licheniformis. In the initial identification of those strains exhibiting antimicrobial activity, 14 were classified as antagonists. One of the isolates (Bacillus sp.) indicated bacteriocinogenic activity, with a deformed inhibition halo on S. mutans by the addition of trypsin. These results suggest that this bacterial isolate may be applicable to biotechnological use to combat the main etiological agent of caries in humans. Further studies are needed to evaluate the bacteriocinogenic nature of the antimicrobial activities of the other 13 antagonistic bacterial isolates.

Association between socioeconomic factors, behavioral, general health and oral mucosa status in elderly. / Associação entre fatores socioeconômicos, comportamentais, saúde geral e condição da mucosa bucal em idosos.

This study aimed to investigate the association between socioeconomic and behavioral factors, general health, oral health, and plaque accumulation and oral mucosa condition outcomes in the elderly. This is a cross-sectional study conducted from 2004 to 2005 with 785 elderly dwellers of the city of Carlos Barbosa (RS), Brasil. We used questionnaires to collect socioeconomic, behavior and health status data. The physical examination of the oral structures comprised the Mucosal-Plaque Index proposed by Henriksen (MPS). A higher prevalence of moderate/severe plaque accumulation was observed in the elderly group, in less educated male elderly. The use of full upper dentures and income under one minimum wage were protective factors for moderate/severe plaque accumulation. Only the variables of the first block of the conceptual structure, male gender (OR = 2.13; 95% CI 1.26-3.61) and lower education (OR = 1.37; 95% CI 1.06-1.78) remained associated with an unacceptable MPS score. The findings suggest that, as per MPS, less educated male elderly are more likely to have poor oral health.

O objetivo deste estudo foi investigar a associação entre fatores socioeconômicos, comportamentais, saúde geral, saúde bucal e os desfechos de acúmulo de placa e condição de mucosa bucal em idosos. Este estudo transversal, conduzido entre 2004 e 2005, incluiu 785 idosos de Carlos Barbosa, RS. Questionários foram utilizados para coleta de dados socioeconômicos, comportamentais e estado de saúde. O exame físico das estruturas bucais e o Índice de Mucosa e de Placa de Henriksen (MPS) foram utilizados para categorizar os desfechos. Observou-se maior prevalência de acúmulo de placa moderado/grave entre os idosos mais velhos, do sexo masculino e com menor escolaridade. O uso de prótese dental total superior e renda de até 1 salário mínimo foram fatores de proteção para acúmulo de placa moderado/grave. Apenas as variáveis do primeiro bloco da estrutura conceitual, sexo masculino (OR = 2,13; IC95% = 1,26-3,61) e menor escolaridade (OR = 1,37; IC95% = 1,06-1,78) permaneceram associados como risco à presença de escore inaceitável do MPS. Os achados sugerem que idosos do sexo masculino e com menor escolaridade têm maior chance de saúde bucal precária, conforme o MPS.

[72-month evaluation of an oral health prevention strategy in schoolchildren]. / Evaluación a 72 meses de una estrategia de prevención en salud oral en escolares.

OBJECTIVE: Given the high prevalence of caries and periodontal disease globally, and its cumulative process from an early age, effective strategies are required to influence healthy habits that are formed in a sustainable manner, taking advantage of common spaces such as school. The objective was to evaluate for 72 months an oral health prevention strategy in schoolchildren. METHODS: This quasi-experimental study considered an initial sample of 350 students with similar cultural and socioeconomic conditions, which was later reduced to 220, after the 72 months. The tooth brushing practice was carried out at school daily; with teacher motivation and leader in oral health formation. Intervention was supervised all time long. to At the beginning and end of the 72 months, the following epidemiological indexes were taken: Silness-Loe plaque index, Loe-Silness Gingival index, brushing skill index by Simmons Smith & Gelbie (ISSG), and the MEDI-MED index that dichotomically considered: healthy permanent teeth, health of the gums and good attitude towards dental health. The statistical analysis included measures of central tendencies. The difference in averages of the indices was determined by the Mann-Whitney U test. RESULTS: The average of the indices: initial (II) and final (IF) registered as follows: gingival (II: 0.63-IF: 0.27) and bacterial plaque (II: 0.99-IF: 0.41) with a difference p <0.05. The index (ISSG) indicated a dental plaque removal of 82.18%.MEDI-MED index "healthy permanent teeth" (II: 91% - IF: 59%); Gum (II: 14% - IF: at 85%) and the "Mind" component (II: 96% - IF: 87%). CONCLUSIONS: The preventive strategy evaluated significantly reduced the rates of bacterial and gingival plaque. The MEDI-MED index indicated decreased in healthy permanent teeth and a positive attitude towards dentistry.

OBJETIVO: Dada la alta prevalencia de caries y enfermedad periodontal a nivel global, y su proceso acumulativo desde temprana edad, se requieren estrategias efectivas para incidir en hábitos saludables que se formen de manera sostenible, aprovechando espacios comunes como la escuela. El objetivo de este estudio fue evaluar a 72 meses una estrategia de prevención en salud oral en escolares. METODOS: Esta investigación cuasi-experimental, longitudinal consideró una muestra inicial de 350 escolares con condiciones culturales y socioeconómicas similares, que después de 72 meses se redujo a 220. La práctica de cepillado dentro de la escuela se realizó diariamente, con motivación de sus maestros y formación de lideres de salud oral. Durante todo el tiempo la intervención estuvo supervisada. Al inicio y a los 72 meses, se tomaron los índices epidemiológicos: de Placa de Silness y Loe, Gingival de Loe y Silness, cepillado de Simmons Smith y Gelbie (ICSG), y el índice MEDIMED que consideró dicotómicamente: dientes permanentes sanos, salud de la encía y buena actitud hacia la odontología. El análisis estadístico incluyó medidas de tendencia central. La diferencia de promedios de los índices se determinó con la prueba U de Mann Whitney. RESULTADOS: Los promedios de los índices iniciales (II) y finales (IF) registraron así: gingival (II: 0,63-IF: 0,27) y placa bacteriana (II: 0,99-IF: 0,41) con una diferencia p <0,05. El índice (ICSG) indicó una remoción de placa dental del 82,18%. El índice MEDIMED: "dientes permanentes sanos" (II: 91% - IF: 59%); encía (II: 14% - IF: a 85%) y el componente "Mente" (II: 96 % - IF: 87%). CONCLUSIONES: La estrategia preventiva evaluada disminuyó los índices de placa bacteriana y gingival en forma significativa. El índice MEDIMED indicó disminucion en dientes permanentes sanos y disminución de una actitud positiva hacia la odontologia.

Prevalence, Severity, and Risk Factors of Gingival Inflammation in Caribbean Adults: A Multi-City, Cross-Sectional Study.

OBJECTIVE: To estimate the prevalence, severity, and associated risk factors of gingival inflammation in a group of adults from Kingston, Jamaica; Santo Domingo, Dominican Republic; and San Juan, Puerto Rico. METHODS: In this representative cross-sectional study, participants completed medical and oral health questionnaires and received an oral clinical examination by trained and calibrated examiners. Clinical assessments included: gingival health (modified Löe-Silness index), visible plaque and presence of calculus. Findings were summarized as mean overall and interproximal gingival indices (GI; IGI), gingival bleeding index (GBI), gingival inflammation prevalence (GI>=0.5) and severity (mild, moderate, severe), mean and interproximal visible plaque indices (VPI; IVPI), and calculus index. Multivariate logistic regression was used to evaluate the associations between risk factors and gingival bleeding on probing (BOP) at >= 40% sites;. odds ratios were estimated. RESULTS: All 1,847 participants presented gingival inflammation; most (81.9%) had moderate inflammation. Mean GI, VPI, IVPI, and calculus indices were 1.49, 0.94, 0.96, and 0.66, respectively; most participants presented a VPI >= 30%. BOP >= 40% of sites was significantly associated with education (ORmiddle/technical vs. university education=1.61; p =0.001 and ORnone/basic vs. university= 2.86; p<0.001), calculus index (OR: 10.35), VPI >= 30% (OR: 7.85; p<0.001 for both), and being a resident of Kingston or Santo Domingo (vs. San Juan, OR: 4. 74 and OR: 7.09, respectively), after adjusting for age, gender, smoking, dental visit frequency, diabetes, and hypertension. CONCLUSION: Gingival inflammation was highly prevalent. Most participants presented moderate gingival inflammation. Educational attainment, dental calculus, and VPI >= 30% were strongly associated with gingival inflammation.

A multicenter study of oral health behavior among adult subjects from three South American cities.

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.

Prevalence of plaque and dental decay in the first permanent molar in a school population of south Mexico City. / Prevalencia de placa dentobacteriana y caries dental en el primer molar permanente en una población escolar del sur de la Ciudad de México

Background: The first permanent molar is susceptible to acquire tooth decay since its eruption, due to its anatomy and because it has been exposed before other teeth. Method: An observational, prolective, transversal and comparative study in 194 students, with an average age of 9.9 ± 1.8 years. The evaluation of the dentobacterial plate (DBP) was analyzed using the O'Leary index and the tooth decay experience with the DMFS (sum of decayed, missing, extracted and filling dental surfaces) and DMFT (sum of decayed, missing, extracted and filling per tooth) indexes. Results: The prevalence of DBP in the first permanent molar was of 99.4% and tooth decay of 57.2%. The value of DMFT was 1.4 ± 1.4. The tooth decay experience was higher in children from 7.10 years old with a value of 2.2 ± 2.3, who are 7.9 times more likely to develop lesions than younger children (odds ratio: 8.9; 95% confidence interval: 4.1-19.5; p < 0.0001). We found an association between age and the values of the tooth decay experience indexes; even though these were weak in the case of DMF (r = 0.439), the model allowed to explain 19% of the association, and 22% for DMFT (r = 0.464). Conclusions: Tooth decay develops rapidly in the first permanent molars; however, it does not receive the necessary care because it is usually unknown that it is a permanent tooth.

Introducción: El primer molar permanente (PMP) es susceptible de caries a partir de su erupción por su anatomía y porque ha estado expuesto antes que otros dientes. Métodos: Estudio observacional, prolectivo, transversal, comparativo, en 194 escolares con una media de edad de 9.9 ± 1.8 años. La valoración de la placa dentobacteriana (PDB) se realizó con el índice de O'Leary, y la experiencia de caries con los índices CPOS (suma de superficies dentales cariadas, perdidas/extraídas y obturadas) y CPOD (suma de dientes cariados, perdidos/extraídos y obturados). Resultados: La prevalencia de PDB en el PMP fue del 99.4%, y la de caries, del 57.2%. El valor del CPOD fue de 1.4 ± 1.4. La experiencia de caries por superficie dental en los niños de 7.10 años de edad fue de 2.2 ± 2.3 y son 7.9 veces más susceptibles a desarrollar lesiones (razón de momios: 8.9; intervalo de confianza al 95%: 4.1-19.5; p < 0.0001) que los menores de esa edad. Se detectó asociación con la variable edad y los valores de los índices de experiencia de caries; aun cuando estas son débiles en el caso del CPOS (r = 0.439), el modelo permitió explicar el 19% de la asociación, y el 22% para el CPOD (r = 0.464). Conclusiones: La caries dental se desarrolla rápidamente en los PMP. En general, no se le da la importancia debida porque se desconoce que se presenta en un diente permanente.

A multicenter study of oral health behavior among adult subjects from three South American cities

Abstract 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.

Associação entre fatores socioeconômicos, comportamentais, saúde geral e condição da mucosa bucal em idosos / Association between socioeconomic factors, behavioral, general health and oral mucosa status in elderly

Resumo O objetivo deste estudo foi investigar a associação entre fatores socioeconômicos, comportamentais, saúde geral, saúde bucal e os desfechos de acúmulo de placa e condição de mucosa bucal em idosos. Este estudo transversal, conduzido entre 2004 e 2005, incluiu 785 idosos de Carlos Barbosa, RS. Questionários foram utilizados para coleta de dados socioeconômicos, comportamentais e estado de saúde. O exame físico das estruturas bucais e o Índice de Mucosa e de Placa de Henriksen (MPS) foram utilizados para categorizar os desfechos. Observou-se maior prevalência de acúmulo de placa moderado/grave entre os idosos mais velhos, do sexo masculino e com menor escolaridade. O uso de prótese dental total superior e renda de até 1 salário mínimo foram fatores de proteção para acúmulo de placa moderado/grave. Apenas as variáveis do primeiro bloco da estrutura conceitual, sexo masculino (OR = 2,13; IC95% = 1,26-3,61) e menor escolaridade (OR = 1,37; IC95% = 1,06-1,78) permaneceram associados como risco à presença de escore inaceitável do MPS. Os achados sugerem que idosos do sexo masculino e com menor escolaridade têm maior chance de saúde bucal precária, conforme o MPS.

Abstract This study aimed to investigate the association between socioeconomic and behavioral factors, general health, oral health, and plaque accumulation and oral mucosa condition outcomes in the elderly. This is a cross-sectional study conducted from 2004 to 2005 with 785 elderly dwellers of the city of Carlos Barbosa (RS), Brasil. We used questionnaires to collect socioeconomic, behavior and health status data. The physical examination of the oral structures comprised the Mucosal-Plaque Index proposed by Henriksen (MPS). A higher prevalence of moderate/severe plaque accumulation was observed in the elderly group, in less educated male elderly. The use of full upper dentures and income under one minimum wage were protective factors for moderate/severe plaque accumulation. Only the variables of the first block of the conceptual structure, male gender (OR = 2.13; 95% CI 1.26-3.61) and lower education (OR = 1.37; 95% CI 1.06-1.78) remained associated with an unacceptable MPS score. The findings suggest that, as per MPS, less educated male elderly are more likely to have poor oral health.

Se utilizaron fichas epidemiológicas que cuentan con consentimientos y asentimientos debidamente firmados, las cuales reposan en el archivo del departamento de investigación de la carrera de Odontología de la UCACUE. Los valores pesquisados fueron vertidos en fichas digitales, que se almacenaron en una base de datos en el programa EPI INFO ver 7.2 y posteriormente se tabularon en el programa Excel. Resultados: El IHO-S parroquial promedio se estableció en 1,09, donde el 61,62% (114 escolares) mostró un nivel bueno, no existiendo diferencia estadísticamente significativa entre los géneros. El 84,32% (156 escolares) presentó un nivel bueno de placa bacteriana blanda, mientras que el 61,08% (113 escolares) mostró ausencia de placa bacteriana calcificada. Las unidades educativas presentaron un IHO-S promedio entre 0,93 ­ 1,29. Conclusiones: La mayoría de los escolares presentan un buen nivel de higiene oral, no encontrándose diferencia estadísticamente significativa entre los géneros. El nivel bueno predominó en el índice de placa bacteriana blanda, mientras que en la placa bacteriana calcificada prevaleció su ausencia. Casi la totalidad de las unidades educativas presentaron un nivel bueno de Índice de Higiene Oral. (AU)

Caries Dental su Asociación con el Índice de Masa Corporal en una Población Joven Adulta / Dental Caries its Association with Body Mass Index in a Young Adult Population

RESUMEN: Este estudio tiene como objetivo determinar la distribución del Índice de Masa Corporal y su asociación con la caries dental en estudiantes de primer ingreso período 2016 de la carrera de Cirujano Dentista de la Facultad de Estudios Superiores Zaragoza UNAM. El estudio fue transversal, descriptivo y observacional, en una muestra por conveniencia de 335 estudiantes que entregaron su consentimiento firmado para participar en este estudio. El bajo peso, sobrepeso y obesidad se midió a través del Índice de Masa Corporal (IMC), e interpretado por los criterios establecidos en la Norma Oficial Mexicana NOM-008-SSA3-2010, para el tratamiento integral del sobrepeso y la obesidad y la caries dental por el indicador epidemiológico de Dientes cariados, perdidos y obturados (CPOD). La información se capturó en el Programa Estadístico SPSS versión 17.0. El 3,3 % de esta población presentó bajo peso con un promedio de caries dental de 6,3±5. El 54 % normal con un CPOD de 7,6±4,8. El 31 % con sobrepeso y un promedio de caries de 7,0±5,1. El 9,3 % con obesidad grado 1 y 7,3±3,6 dientes cariado y el 2,4 % con obesidad grado 2 y 5,2±4,1 con historia de caries dental. El 31 % de los estudiantes que participaron en este estudio presentaron sobrepeso, por lo que existe un riesgo muy elevado si no se actúa con medidas preventivas y de promoción de la salud, de que estos alumnos en un futuro se conviertan en obesos y con ello tener repercusiones en su salud general.

ABSTRACT: The objective of this study is to determine the body mass index and its association with dental caries, in first-year students of the dental surgeon degree program for the 2016 school term, Zaragoza College for Higher Education, UNAM. This was a cross, descriptive and observational study, in a sample of 335 students. Low weight, overweight and obesity were measured through body mass index and interpreted with the official Mexican Norm NOM008-SSA3-2010, for integral treatment of overweight, obesity and dental caries. The measures were taken according to the epidemiologic indicator of decayed, lost and sealed teeth (dlst). We used statistical program SPSS version 17.0 for the information. In the studied population, 3.3 % presented low weight, with an average of dental caries of 6.3±5; 54 % presented normal weight with a DLST of 7.6±4.8; 31 % presented with overweight and an average of caries of 7.0±5.1; 9.3 % with obesity grade 1 and 7.3±3.6 tooth decay and lastly 2.4 % with obesity grade 2 and 5.2±4.1 with a history of dental caries. Of the students participating in this study, 31 % presented overweight, indicating a high risk of poor oral health. If preventive measures in their overall health are not implemented early on, these students are at risk of obesity and general health repercussions in the future.
