Comparative analysis of microbiome in coronal and root caries.

BACKGROUND: The global rise in the elderly population has increased the prevalence of root caries. Streptococcus mutans, Lactobacilli and Actinomyces are considered the primary pathogens of dental caries in culture-based studies. This study aimed to investigate bacterial profiles in coronal and root caries lesions and determine the association of specific bacterial genera at each site. METHODS: Dentine samples from carious lesions were collected from 22 extracted teeth using an excavator. Microbial DNA was extracted from the samples using a protocol developed for this study. 16S rRNA gene amplicon sequencing was employed for microbial analysis. PCR amplification targeted the V3-V4 region of the bacterial 16S rRNA, and the amplicon sequencing used an Illumina MiSeq system (2 × 300 bp paired-end reads). Statistical analysis was performed by the Phyloseq and DESeq2 packages in R. RESULTS: In coronal caries, Olsenella, Lactobacillus and Prevotella were the most prevalent genera, comprising approximately 70% of the microbiome community. In the root caries, however, although Olsenella, Prevotella and Lactobacillus remained the dominant genera, they accounted for only half of the microbiome community. This study identified significant differences in alpha diversity indices between the coronal and root caries. LEfSE analysis revealed several unique genera in each caries lesion. CONCLUSION: The microbiome of root caries lesions was richer and more complex than the coronal caries microbiota. The results suggest that lesion-related variations in the oral microflora may be detected in carious dentine.

Reliability of impedance spectroscopy versus digital radiograph and ICDAS-II in occlusal caries detection: a prospective clinical trial.

The traditional methods in early caries detection had many limitations. So, this study aimed to evaluate the clinical performance of alternating current impedance spectroscopy ACIST in comparison with digital radiograph and ICDAS-II in detection of occlusal carious lesions. Occlusal surfaces of molar and premolar teeth from 40 adult participants were examined by two observers using three diagnostic methods: (1) international caries detection and assessment system (ICDAS-II) (2) digital radiograph (DR) and (3) Cariescan Pro device (ACIST). Agreement analysis and the difference in sensitivities and specificities were evaluated. The results showed an excellent agreement in the different groups. The difference from the visual tactile against ACIST scoring for enamel caries detection, was statistically significant (p = 0.012) and the agreement was moderate (k = 0.509). For dentinal caries the difference was not statistically significant (p > 0.05) and the agreement was similarly moderate (k < 0.6). The difference from the digital radiograph against ACIST scoring, for enamel caries, digital radiography had significantly higher sensitivity and specificity than ACIST (p < 0.001) while for dentinal caries detection and overall, ACIST had higher sensitivity and digital radiography had higher specificity and the difference was statistically significant (p < 0.001). Visual-tactile examination is a considered as feasible and valid technique for occlusal caries detection, digital radiography is superior to ACIST in diagnosing enamel caries, but it could underestimate the caries depth, ACIST is a reliable tool for detecting occlusal caries in dentin.

Clinical, Radiographic, and Histological Changes in Enamel and Dentin, According to Caries Care International™ Evaluation, In Permanent Posterior Teeth: An Observational Study / Cambios Clínicos, Radiográficos e Histológicos en Esmalte y Dentina, Según Evaluación de Caries Care International™, en Dientes Posteriores Permanentes: Un Estudio Observacional

SUMMARY: CariesCare International ™ practical guide is a tool for the comprehensive assessment and treatment of caries that synthesizes clinical and radiographic diagnosis and risk factors, classifying the severity, progression, and activity of lesions. The objective of this study was to analyze the validity and prediction characteristics of the proposed dental caries classification in the CariesCare International ™ practical guide as a reference through clinical and radiographic evaluation versus histological evaluation. Ninety-seven permanent posterior teeth were evaluated, and clinical and radiographic diagnoses were determined according to parameters defined in the CariesCare International™ guide as a reference. Subsequently, histological evaluation was performed to compare each stage of dental caries progression, and statistical analysis was applied. When comparing the validity and prediction values between radiographic and clinical diagnoses in relation to histological evaluation, a low sensitivity and high specificity relationship was found. The sensitivity and specificity percentages between the clinical and radiographic methods show that the clinical method has a lower number of false negatives. Histological changes in dental tissue were evident from the earliest stages of lesions, even in those not related to the caries process, indicating that the dentist should be careful when deciding on a treatment plan and take into account all variables involved in the caries process, as proposed by the CariesCare International ™ guide.

La guía práctica CariesCare International™ es una herramienta para la evaluación y tratamiento integral de la caries que sintetiza el diagnóstico clínico y radiográfico y los factores de riesgo, clasificando la gravedad, progresión y actividad de las lesiones. El objetivo de este estudio fue analizar la validez y características de predicción de la clasificación de caries dental propuesta en la guía práctica CariesCare International™ como referencia a través de la evaluación clínica y radiográfica versus la evaluación histológica. Se evaluaron noventa y siete dientes posteriores permanentes y se determinaron diagnósticos clínicos y radiográficos según parámetros definidos en la guía CariesCare International™ como referencia. Posteriormente se realizó una evaluación histológica para comparar cada etapa de progresión de la caries dental y se aplicó análisis estadístico. Al comparar los valores de validez y predicción entre los diagnósticos radiológicos y clínicos en relación con la evaluación histológica, se encontró una relación de baja sensibilidad y alta especificidad. Los porcentajes de sensibilidad y especificidad entre el método clínico y radiográfico muestran que el método clínico tiene un menor número de falsos negativos. Los cambios histológicos en el tejido dental fueron evidentes desde las primeras etapas de las lesiones, incluso en aquellas no relacionadas con el proceso de caries, lo que indica que el odontólogo debe tener cuidado al decidir un plan de tratamiento y tener en cuenta todas las variables involucradas en el proceso de caries, tal como propone la guía CariesCare International™.

Efficiency of casein phosphopeptide amorphous calcium phosphate versus topical fluorides on remineralizing early enamel carious lesions - A systematic review and meta analysis.

Objective: To assess the remineralizing efficiency of caesin phosphopepdide amorphous calcium phosphate (CPP-ACP) versus topical fluorides on early enamel lesions in vivo. Data sources: PubMed, Web of Science, Scopus, EBSCO were searched based on the PICOS criteria up to December 2022 with English language restriction. All relevant studies were subjected to two separate reviews before being included at the title, abstract, and full text levels. Study selection: 41 studies were reviewed and 11 selected for inclusion in the final sample for the review. All were randomized clinical trials with the follow-up period of the studies ranging from 3 to 12 months. Out of the 11 studies, only two are with low risk of bias on assessment with Cochrane risk of bias assessment tool, while the other nine articles were with the moderate and high risk of bias. Conclusions: Conflicting evidence exists on the clinical efficacy of CPP-ACP compared to the various fluoride forms tested, and no adverse effect associated with CPP-ACP use was discovered in comparison to fluorides that had certain detrimental health impacts. Although, the review results in favor of both fluorides and CPP-ACP with similar clinical efficiency, when ill effects are considered the CPP-ACP can be a choice of remineralizing early enamel lesions. However, before concrete suggestions can be given, high-quality, well-designed clinical research in this area are still necessary. Clinical significance: A considerable remineralizing impact has been shown in both in vitro and in vivo experiments, making CPP-ACP/CPP-ACPF a more promising remineralizing agent than fluorides. Therefore, this can be applied clinically to early enamel carious lesion.

Progression of proximal caries in primary molars using the radiographic ICDAS: a retrospective cohort study.

PURPOSE: To evaluate the proximal caries progression in primary molars using the radiographic International Caries Detection and Assessment System (ICDAS). METHODS: A study was conducted on 196 children aged 3-9 years old who underwent the clinical examination and bitewing radiography during baseline and 6-month (and over) follow-up visits. The primary molars bitewing radiographs with initial enamel caries (RA1 and RA2) or outer dentine caries (RA3) of proximal surfaces were included. Caries advancement was scored using ICDAS criteria and statistical analyses with the chi-square test. Median survival time was evaluated using Kaplan-Meier survival curves and log-rank tests. RESULTS: A total of 439 surfaces of primary molars were included in this study and an averaged follow-up period of enamel and dentine caries group were 18.3 ± 9.6 months and 16.5 ± 9.5 months respectively. The progression of proximal enamel lesions significantly differed between primary maxillary and mandibular molars (p = 0.002) and among each patient's primary mandibular second molar and the others (p = 0.002). On the contrary, the outer dentine caries of each group of primary molars was not different. The median survival time of the initial enamel proximal caries (23.30 months) was non-significantly longer than that of the dentine (20.80 months). CONCLUSIONS: Progressions of the initial enamel proximal caries were significantly different among primary molars at the average 18.3-month follow-up. The median survival period of the enamel proximal caries was more extended than that of dentine but without statistical difference. These results provide essential information for dentists regarding an appropriate appointment for bitewing examinations.

Assessment of dental caries based on ICDAS and WHO criteria: A comparative study.

BACKGROUND: The decayed, missing, and filled teeth (DMFT/dmft) index recommended by the World Health Organization (WHO), which measures the prevalence of caries based on the presence of cavitated caries lesions, is the most used dental caries index in epidemiological studies. Early diagnosis of noncavitated carious lesions enables preventive measures, which has the potential to prevent dental caries-related morbidity and reduce the financial burden associated with restorative or rehabilitative dental care. The International Caries Detection and Assessment System (ICDAS II) incorporates both the cavitated and noncavitated carious lesions with acceptable reliability. AIM: To compare dental caries prevalence based on ICDAS II and WHO criteria. DESIGN: A cross-sectional study was conducted among 362 children visiting People's Dental College and Hospital, Nayabazar, Kathmandu, Nepal to study dental caries prevalence based on the ICDAS II and WHO criteria. RESULTS: Among the study population, 290 (90.34%) and 169 (68.42%) children had dental caries in primary and permanent teeth according to the ICDAS II criteria, whereas according to WHO criteria, 267 (83.18%) and 107 (43.32%) had dental caries in primary and permanent teeth, respectively. The prevalence of dental caries was significantly higher (p < .001) according to ICDAS II criteria than the prevalence based on WHO criteria in both dentitions. CONCLUSION: This study showed a significant difference in dental caries prevalence between the ICDAS II and WHO methods of caries diagnosis. The presence of noncavitated carious lesions was alarming. To enable detection of early/noncavitated carious lesions, ICDAS II rather than WHO criteria of caries diagnosis may be a more a valuable tool.

Prevalence of Dental Caries Among Costa Rican Male Students Aged 12-22 Years Using ICDAS-II / Prevalencia de caries en varones costarricenses escolarizados de 12 a 22 años utilizando ICDAS-II

ABSTRACT: Objective: Dental decay is a public health challenge in Low- and Middle- Income Countries, particularly for young people, often confronted to healthcare access barriers. The aim of this study was to determine the prevalence and severity of dental caries among young male students in Costa Rica. Study design: A cross-sectional study was performed in 428 Costa Rican male students aged 12-22 years, who attended a nonprofit social welfare boarding school in 2019. A clinical examination was ran by three calibrated examiners following the International Caries Detection and Assessment System (ICDAS-II). Results: Caries prevalence was estimated at 83%, 15% have lost a tooth due to dental decay, 61% have at least one filled tooth, 36% have at least one filled and decayed tooth. The most frequent caries lesions were codes 2-Inactive (46.7%) and code 1-Inactive (23.8%). DMFT indicated a mean index using ICDAS-II 1-6>0 codes of 7.89. Using ICDAS-II 3-6>0 as threshold, the index decreases to 3.94. Finally, the lower and upper first permanent molars were found to be the most affected teeth. Conclusions: Dental caries experience represents a significant public health burden in young people, requiring better access to public dental healthcare.

Implicación clínica del protostílido: una mirada desde la antropología dental y la odontología no invasiva / Clinical implication of protostlylid: a point of view from dental anthropology and non-invasive dentistry

RESUMEN De acuerdo al modelo patológico multifactorial, la morfología dental ha sido asociada como uno de los factores etiológicos de la caries al favorecer el acumulo de restos alimenticios y la retención de biopelícula. Uno de los rasgos morfológicos dentales más frecuentes de la población colombiana es el punto P del protostílido, el cual se constituye en una fosa que se expresa en el surco de desarrollo vestibulomesial de los molares inferiores, región que le sigue a la superficie oclusal como uno de los sitios en donde se desarrollan con más frecuencia lesiones cariosas. Sin embargo, el desconocimiento de este rasgo morfológico por la mayoría de los odontólogos hace que el sistema morfológico del protostílido sea mal diagnosticado, lo que conlleva en muchos casos al sobretratamiento de dicha fosa con terapéuticas invasivas, las cuales, podrían ser evitadas con un conocimiento adecuado de la morfología dental y con un manejo preventivo o con técnicas no invasivas. Por tanto, el objetivo de esta revisión de tema es reconocer la expresión del punto P del protostílido y realizar una aproximación a las implicaciones clínicas del mismo y las posibilidades diagnósticas y terapéuticas conservadores que ofrece la odontología para controlar el acumulo de restos alimenticios y la retención de biopelícula.

ABSTRACT According to the multifactorial pathological model, dental morphology has been associated as one of the etiological factors of caries by favoring the accumulation of food remains and biofilm retention. One of the most frequent of non-metric dental traits of the Colombian population is the P point of the protostylid, which is constituted in a fossa that is expressed in the bucomesial development groove of the lower molars, a region that follows the occlusal surface as one of sites where carious lesions develop more frequently. However, the lack of knowledge of this morphological feature by most dentists makes the morphological system of the protostylid misdiagnosed, which in many cases leads to the overtreatment of this pit with invasive therapies, which could be avoided with a knowledge adequate dental morphology and with a preventive management or non-invasive techniques. Therefore, the aim of this review of the subject is to reconcile the expression of the P point of the protostylid and to make an approximation to the clinical implications of the same and the conservative diagnostic and therapeutic possibilities offered by dentistry to control the accumulation of food rests and retention of dental biofilm.

Especificidad y Sensibilidad de Sistema ICDAS TM versus Índice COPD en la Detección de Caries / Specificity and Sensitivity of the ICDAS TM System versus the DMFT Index in Caries Detection

RESUMEN: La caries dental no tratada es la enfermedad crónica más frecuente en adultos y la caries no tratada en dientes temporales es la décima enfermedad crónica más frecuente. En Chile los adultos presentan un COPD promedio entre 3,76 - 22,16, pero los estudios no son en población representativa y no existen estudios comparativos entre ceod/ COPD e ICDASTM. A nivel mundial, su prevalencia puede alcanzar el 100 % de la población estudiada. Se buscará evaluar si existen diferencias en la sensibilidad y especificidad en la detección de caries utilizando ICDASTM y ceod/COPD. Se realizó una revisión sistemática cualitativa realizando una búsqueda sobre los índices de caries ceod/COPD y sistema ICDASTM, tanto en Chile como a nivel mundial, en las bases de datos Medline, ClinicalKey y SciELO encontrando 3.581, de ellos, 21 se leyeron por completo y 14 cumplieron nuestros criterios. La sensibilidad y especificidad es mayor con ICDASTM que con el índice ceod/COPD y entrega hasta un 43 % más información al detectar lesiones no cavitadas, pero necesita de mayor tiempo para su realización y más recursos al utilizar luz, aire comprimido y una profilaxis previa al examen. Capacitaciones previas, conocimientos y experiencia en ICDASTM son fundamentales para el mejor resultado, estudios demostraron que mientras mayor experiencia, la sensibilidad y especificidad aumentaba a diferencia del índice ceod/COPD. Se deben realizar más estudios comparativos entre ambos índices e incluir ICDASTM en niños por su capacidad de detectar lesiones no cavitadas las cuales son las más prevalentes en dientes temporales.

ABSTRACT: Untreated dental caries is the most frequent chronic disease in adults and untreated caries in primary teeth is the tenth most frequent chronic disease. In Chile, adults have an average DMFT between 3.76-22.16, but the studies are not in a representative population and there are no comparative studies between dmft/DMFT and ICDASTM. Worldwide, its prevalence can reach 100 % of the population studied. The objective of the study was to evaluate if there are differences in the sensitivity and specificity in the detection of caries using ICDASTM and dmft/DMFT. A qualitative systematic review was done, carrying out a search on the dmft/DMFT index and the ICDASTM system, both in Chile and worldwide, in the Medline, ClinicalKey and SciELO databases, finding 3,581, of which, 21 were read completely and 14 met the inclusion and exclusion criteria. The sensitivity and specificity is greater with ICDASTM than with the dmft/DMFT index and delivers up to 43 % more information when detecting non-cavitated lesions, but it needs more time for its realization and more resources because it needs to use light, compressed air and prophylaxis before the examination. Previous training, knowledge and experience in ICDASTM are fundamental for the best results. Studies showed that the greater the experience, the sensitivity and specificity increased, unlike the dmft/DMFT index. More comparative studies should be conducted between both indexes and include ICDASTM in children for their ability to detect non-cavitated lesions, which are the most prevalent in temporary teeth.

Herramientas actuales para el diagnóstico, manejo y control de la caries dental. Parte I / Current tools for diagnosis, handling and control of dental caries. Part I

El diagnóstico de caries dental ya no es más como el diagnóstico tradicional que mencionaba histológicamente el inicio y el final de una cavidad. Se ha demostrado que los criterios de diagnóstico y las herramientas utilizadas en la detección de lesiones de caries afectan la toma de decisiones para su tratamiento. Hoy en día, la caries dental es considerada un proceso; por ello, en el presente artículo, se describen nuevas propuestas que nos ayudarán con el diagnóstico, manejo y control de dicha enfermedad. Los criterios Cambra e Icdas son los que teóricamente tienen sustento bajo evidencia científica de lo que es actualmente la patología y su desarrollo, por lo que se describen los antecedentes históricos de su desarrollo, sus principales características, y se proponen opciones de integración al proceso diagnóstico actual a favor de una mayor conservación de la estructura dentaria. (AU)

The diagnosis of dental caries is no longer like the traditional diagnosis that histologically mentioned at the beginning and end of a cavity. It has been shown that the diagnostic criteria and tools used in the detection of caries lesions affect the decision-making process for caries treatment. Today tooth decay is considered as a process; That is why in this article new proposals are presented that will help us with the diagnosis, management and control of said disease. The criteria Cambra and Icdas, are those that theoretically have sustenance under scientific evidence of what is currently the pathology and its development; Therefore, the historical background of the development of Cambra and Icdas, its main characteristics are described, and integration options are proposed to the current diagnostic process in favor of greater preservation of the dental structure.

Capacidad buffer de la saliva y su relación con la prevalencia de caries, con la ingesta de diferentes bebidas comerciales / Buffer capacity of saliva and its relation to the prevalence of caries, with the intake of different commercial drinks

Resumen En la actualidad tanto el consumo de jugos, como de bebidas gaseosas, es muy común en la dieta diaria de la población infantil, estas ofrecen diferentes sabores, además de un alto contenido de azúcar. En este estudio se hizo un análisis de la capacidad buffer de la saliva ante la ingesta de diferentes tipos de bebidas consideradas saludables y no saludables. Se utilizaron dos tipos de instrumentos, un examen clínico aplicado a 62 estudiantes para determinar la prevalencia de caries según ICDAS y un segundo instrumento que consta de una tabla aplicada a los mismos 62 estudiantes con la finalidad de analizar la capacidad buffer de la saliva mediante la toma del pH a intervalos de 15, 35 y 45 minutos después de ingerir las bebidas. Como conclusión se obtuvo que para las bebidas consideradas no saludables el pH tardó más en neutralizarse, mientras que la bebida saludable logró su neutralización más rápido, con una baja prevalencia de caries.

Abstract Nowadays the consumption of juices, and soft drinks, is very common in the children's diet, they offer different flavours and a high content of sugar. In this study, an analysis of the buffer capacity of the saliva was made in view of the intake of different types of beverages considered healthy and unhealthy. Two types of instruments were used, a clinical test applied to 62 students to determine the prevalence of caries according to ICDAS and a second instrument that consists of a chart applied to the same 62 students with the purpose of analyzing the buffer capacity by taking the pH on intervals of 15, 35 and 45 minutes after drinking the beverages. As a conclusion, it was obtained that for the drinks considered unhealthy, the pH took longer to neutralize, while the healthy drink achieved its neutralization faster, with a low prevalence of caries.

Toma de decisiones para el tratamiento de caries oclusales en el sistema de salud público brasileño / Decision-making for the treatment of occlusal caries in the Brazilian public health system

ABSTRACT Introduction: Caries diagnosis errors have become a public health problem. Objective: Verify the consistency in terms of decision-making between Brazilian dentists from the country's public health system and the International Caries Detection and Assessment System (ICDAS), and evaluate the influence of professional experience on the management of the decay. Methods: There are 80 dentists in the public health service of Recife city, Brazil. All dentists were invited to participate in this cross-sectional study. Forty dentists agreed to answer questions about their decision-making in relation to the treatment of occlusal caries in low, moderate and high-risk caries situations. The time of clinical experience, the use of methods for the assessment of caries risk and the lesion activity were also inquired about. The T-test was applied with a significance level of 5 por ciento to compare the correlation between the International Caries Detection and Assessment System scores regarding the mean age of participants. Results: The disagreement between the dentists and the criteria used by the International Caries Detection and Assessment System for decision-making were mainly related to the sound surfaces or lesions restricted to the tooth enamel. It was thus verified that lack of consistency for the low-risk condition reached a score of 3 (32 percent), while moderate (95 percent) and high-risk (85 percent) conditions lay at a classification code of 0. The time of professional experience was not considered to have interfered with decision-making on any scale, regardless of the risk condition of the patient (p> 0.05). Conclusions: A divergence in terms of decision-making between dentists of the public health system and the International Caries Detection and Assessment System could be observed, specifically regarding sound surfaces or surfaces with lesions restricted to the tooth enamel. Furthermore, professional experience was seen as not influencing the management of caries(AU)

RESUMEN Introducción: Los errores de diagnóstico de caries se han convertido en un problema de salud pública. Objetivo: Verificar la concordancia de la toma de decisiones entre los dentistas brasileños del sistema de salud pública del país y el Sistema Internacional de Detección y Evaluación de Caries (ICDAS), así como evaluar la influencia de la experiencia profesional en el manejo de la caries. Métodos: De los 80 dentistas que existen en servicio público de salud en la ciudad de Recife, Brasil, todos fueron invitados a participar en este estudio transversal. Cuarenta dentistas acordaron responder sobre su toma de decisión en relación con el tratamiento de la caries oclusal en situaciones de caries de bajo, moderado y alto riesgo. El tiempo de experiencia clínica, el uso de métodos para la evaluación del riesgo de caries y la actividad de la lesión también fueron cuestionados. La prueba T, para un nivel de significancia del 5 por ciento, fue aplicada para comparar la correlación entre los escores del Sistema Internacional de Detección y Evaluación de Caries en relación con el promedio de edad de los participantes. Resultados: El desacuerdo entre los dentistas y los criterios utilizados por el ICDAS para la toma de decisiones se concentró en los códigos de clasificación que representan superficies sanas o lesiones restringidas al esmalte de los dientes. Se verificó así que la falta de consistencia para la condición de bajo riesgo se concentró en la puntuación de 3 (32 por ciento), mientras que las condiciones moderada (95 por ciento) y de alto riesgo (85 por ciento) se concentraron en los códigos de clasificación de 0. El factor tiempo de experiencia profesional no interfirió en la prevalencia de concordancia de la toma de decisión para cualquier escore, independientemente de la condición de riesgo del paciente (p> 0,05). Conclusiones: Se pudo observar una divergencia en cuanto a la toma de decisiones entre los dentistas del sistema de salud pública y el Sistema Internacional de Detección y Evaluación de Caries, específicamente con respecto a superficies sanas o superficies con lesiones restringidas al esmalte de los dientes. Además, la experiencia profesional no influyó en el manejo de la caries(AU)

Las variables analizadas fueron: reducción de placa dentobacteriana; prevención y limitación del daño de lesiones cariosas y supervivencia de los tratamientos ejecutados. La prueba estadística utilizada fue la de Wilcoxon, el Análisis de la Varianza (ANOVA), tomando en cuenta la F de Fisher y la Significancia. Resultados: El diagnóstico de placa dentobacteriana óptimo fue de 52.67% en la evaluación inicial, el cual 6 meses después de la intervención incrementó a un 78.67%. En los SFF se encontró una supervivencia a los 3 y 6 meses de 97.25% y 82.27%, y en las obturaciones de 100% y 98.03% respectivamente. En cuanto a la afectación por caries dental inicial se identificó un 18.34%, luego de la intervención se redujo a 4.72%. Conclusión: La intervención mostró a 3 y 6 meses, ser efectiva para prevenir y tratar caries dental en dientes permanentes.

Objective: To determine the effectiveness to 3 and 6 months of an intervention to prevent and treat caries in permanent teeth, in schoolchildren of 9-11 years, attended by five health establishments in the year 2017. Methodology: This research was a community intervention, of quasiexperimental type with pre-post control group, in 150 schoolchildren. In total, 1.970 treatments were executed; of which 165 were remineralization of fluoride varnish; 1501 sealants and 304 fillings; accompanied by oral hygiene education. The variables analyzed were: reduction of dental plaque; prevention and limitation of damage to carious lesions and survival of the treatments performed. The statistical test used was that of Wilcoxon, the Kaplan Meier Survival Estimator, the variance analysis (ANOVA), taking into account Fisher's F and significance. Results: The dental plaque initial diagnosis was optimum with a 52.67% on first evaluation, this increased to a 78.67% after 6 months of intervention. In sealants were found a survival of 97.25% and 85.27% after 3 and 6 months of intervention; in fillings the survival was of 100% and 98.03% respectively. In regards of caries affectation, an 18.34% was identified on initial evaluation, after intervention this was reduced to a 4-72%. Conclusión: The intervention showed within 3 and 6 months, to be effective to prevent and treat dental caries in permanent teeth.

Prevalencia de caries dental y necesidades de tratamiento según ICDAS y CPO en escolares de El Salvador / Dental cavity and treatment needs prevalence according to ICDAS and DMF in schools of El Salvador / Prevalência de cáries dentárias e necessidade de tratamento de acordo com ICDAS e CPO nas escolas de El Salvador / Prévalence des caries dentaires et des besoins de soins chez les écoliers du Salvador selon l'ICDAS et le CAO

Resumen Objetivo: Comparar la prevalencia de caries dental y necesidades de tratamiento según criterios International Caries Detection and Assessment System (ICDAS) y CPO-D, en niños de 7-8 años de Centros Escolares públicos rurales pertenecientes a 16 municipios de El Salvador. Materiales y métodos: El diseño corresponde a una investigación epidemiológica descriptiva transversal realizada a partir de las historias clínicas de 420 escolares de 7 - 8 años de zonas rurales de El Salvador; el diagnóstico de caries se estableció con base en criterios ICDAS. Las variables analizadas fueron: prevalencia de caries y necesidades de tratamientos. El CPO-D/ceo-d se estableció excluyendo las fases precavitacionales de la enfermedad, se empleó T de Student para probar las diferencias de las medias entre índices y la Prueba de Levene para evaluar la igualdad de las varianzas. La significación estadística fue fijada en p <0,05. Resultados: Según ICDAS, cada niño presentó un promedio de 9.52 dientes afectados por caries y 6.24 según CPO. La diferencia encontrada entre índices es significativa en dientes permanentes y en primarios (p<0,05). Los diagnósticos según criterios ICDAS, generaron 4,269 necesidades de tratamientos curativos y 4,475 preventivos; mientras que con CPO, 2,997 tratamientos curativos y ningún preventivo. Conclusiones: ICDAS reflejó una mayor afectación por caries al considerar los estadios precavitacionales; por tanto, permite establecer una diversidad de tratamientos preventivos y de limitación del daño, que, en su mayoría, no es posible indicar con CPO.

Abstract Objective: To compare the prevalence of dental cavity and treatment needs according to International Cavity Detection and Assessment System (ICDAS) and DMF, in 7-8 years old children of rural public school centers belonging to 16 municipal towns of El Salvador. Materials and methods: The design corresponds to a transversal descriptive epidemiological investigation made from clinical histories of 7-8 year- old schoolchildren in rural areas of El Salvador; the diagnosis of dental cavities was established based on ICDAS criteria. The variables analyzed were: caries prevalence and treatment needs. The DMF-T/ dmf-t was established, excluding the precavitation phases of the disease, Student's T was used to test the differences of the means between indexes and the Levene test to evaluate the equality of the variances. The statistical significance was set at p <0.05. Results: According to ICDAS, each child presented an average of 9.52 teeth affected by caries and, according to DMF, 6.24. The difference found between indexes is significant in permanent teeth and in primary teeth (p<0,05). Diagnoses according to ICDAS criteria, generated 4269 needs for curative treatments and 4475 preventive ones; while with DMF, 2997 curative treatments and no preventive ones. Conclusions: ICDAS reflected a higher affectation by dental cavities when considering the precavitation stages; therefore, it allows establishing a diversity of preventive treatments and damage limitation; which, mostly, it is not possible to indicate with DMF.

Resumo Objetivo: Comparar a prevalência de cáries dentárias e necessidade de tratamento de acordo com os critérios do International Caries Detection and Assessment System (ICDAS) e da CPO, em criabas de 7 a 8 años de escolas públicas em áreas rurais pertencentes a 16 municipios de El Salvador. Materiais e métodos: O projeto corresponde a uma investigação epidemiológica descritiva transversal, realizada a partir da história clínicas de 420 alunos de 7 a 8 anos de áreas rurais de El Salvador. O diagnóstico de cárie foi estabelecido com base nos critérios do ICDAS. As variáveis analisadas foram: a prevalencia de cárie e a necessidade de tratamento. O CPO-D/ceo-d foi estabelecido excluindo as fases pré-cavitacionais da doença. Utilizou- se o teste t de student para comparar as médias dos índices e o teste de levene teste de Levene para a igualdade de variançias. A significancia estatística foi definida em p <0,05. Resultados: De acordo com o ICDAS, cada criaba apresentou em média de 9,52 dentes afetados por cáries e 6,24 de acordo com CPO. A diferen9a encontrada entre os índices é significativa nos dentes definitivos e nos primeiros dentes (p<0,05). Os diagnósticos, de acordo com os critérios do ICDAS, criaram 4269 necessidades para tratamentos curativos e 4475 preventivos; mas com os de CPO, apenas 2997 tratamentos curativos e nenhum preventivo. Conclusões: O ICDAS demostrou maior quantidade de dentes afetados por cárie ao considerar as etapas pré-cavitacionais; no entanto, permite estabelecer uma diversidade de tratamentos preventivos e de limitação de danos que, na maior parte das vezes, náo é possível estabelecer com CPO.

Résumé Objectif: Comparer la prévalence des caries dentaires et des besoins de soins selon les criteres du International Caries Detection and Assessment System (ICDAS) et du CAO-D, chez les enfants de 7 a 8 ans de centres scolaires publiques ruraux de 16 municipalités du Salvador. Matériels et méthodes: L'étude est épidémiologique, transversale et descriptive. Elle a été réalisée à partir de l'histoire clinique de 420 écoliers de 7 a 8 ans, de zones rurales du Salvador. Le diagnostic de caries a été établi sur la base des critères ICDAS. Les variables analysées sont la prévalence de caries et les besoins de soins. Le CAO-D / ceo-d a été établi en excluant les stades pré-cavitaires de la maladie. Le test de Student a été utilisé pour comparer les moyennes obtenues pour les indices et le test de Levene pour évaluer l'égalité des variances. La signification statistique a été fixée à p <0,05. Résultats: Selon l'ICDAS, chaque enfant présentait en moyenne 9,52 dents cariées; et selon le CAO 6,24. La différence entre les indices est significative pour les dents permanentes et les primaires (p <0,05). Les diagnostics selon les criteres ICDAS, ont permis d'identifier 4269 besoins de soins curatifs et 4475 préventifs; avec le CAO, 2997 soins curatifs et aucun soins préventif. Conclusions: L'ICDAS a permis de détecter plus d'affectations par caries en raison de sa prise en compte des stades pré-cavitaires; il permet donc d'établir une grande diversité de soins préventifs pour limiter les dommages, ce qui est généralement impossible avec le CAO.

Dental examiners consistency in applying different oral health indices in permanent dentition for a population-based study

Different indices to identify dental diseases have been developed. For population-based studies, it is imperative to use simple and reliable indices, but most importantly, clinical examiners should reach an agreement, in order to increase inter-observer reliability and obtain reliable data. The objective of this study was to describe the calibration process of the Dental Aesthetic Index, Community Periodontal Index, Simplified Oral Hygiene Index and International Caries Detection and Assessment System ICDAS II by two academics from the Public Health Department of Dentistry. All calibrations started with the individual reading of the official documents of each index and, when possible, were followed by a lecture, in-vitro or ex-vivo training and concluded with an in-vivo training. A high inter-observer reliability was obtained between the two academics in all indices.

An evaluation using the international caries detection and assessment system - ICDAS / Cárie dentária em crianças entre 0-5 anos do município de Andes, Colômbia. Avaliação utilizando o Sistema Internacional de Avaliação e Detecção de Cáries -ICDAS

Resumen La falta de información de la situación de caries dental en la primera infancia en Andes, limita las acciones en el marco de la Alianza por un Futuro libre de Caries. Objetivo: establecer la situación de caries dental de los niños y niñas de 0 a 5 años del Municipio de Andes (Colombia). Metodología: fueron examinados 623 niños y niñas para evaluar la presencia y severidad de las lesiones de caries, con base en criterios del Sistema Internacional para la detección y evaluación de caries - ICDAS. Se calcularon las proporciones de experiencia y prevalencia de caries dental, y los índices cICDAS 5-6 opd y cICDAS 1-6 opd. Resultados: el 38,2% tenía experiencia de caries dental severa, cuando se incluyen las lesiones iniciales y moderadas de caries dental la experiencia fue 88,4%. Al año de edad, el 4,9% tenía lesiones severas de caries dental, y a los 5 años el 53,6% presentó este tipo de lesiones. El índice cICDAS 5-6 opd fue 0,15±0,8 al año de edad y 2,79±3,6 a los 5 años; el valor del indicador aumenta a 1,97±2,9 y 9,61±4,6 respectivamente, cuando se incluyen lesiones iniciales y moderadas de caries dental, cICDAS 1-6 opd . Discusión: la enfermedad está presente desde el primer año en el 58,8%, el doble de lo reportado en el país a esta edad (29,3%). Conclusión: los hallazgos resaltan la necesidad de diseñar estrategias integrales para el control de la enfermedad, que involucren la salud bucal en políticas y programas de primera infancia.

Abstract The lack of information on dental caries limits the actions of the program called "Alliance for a Cavity Free Future" in the Andes municipality, Colombia. Objective: to establish a baseline for dental caries in primary dentition among children aged 0 to 5. Methods: a total of 623 children were examined in order to detect the presence of dental caries and its severity. This analysis was conducted using the criteria of the International Caries Detection and Assessment System, ICDAS. In addition, the experience and prevalence ratios were calculated along with the cICDAS 5-6, mft and cICDAS 1-6 mft indices. Results: 38.2% of the children had experienced severe caries (dICDAS 5-6 mft>0); the percentage of caries experienced increased to 88.4% when initial and moderate dental caries lesions were included (dICDAS 1-6 mft>0). The data showed that 4.9% of the one-year-olds had untreated severe carious lesions, and this percentage increased to 53.6% for five-year-olds. The dICDAS 5-6 mft index was 0.15±0.8 for one-year-olds and 2.79±3.6 for five-year-olds, increasing to 1.97±2.9 and 9.61±4.6, respectively when initial and moderate dental caries lesions were included - dICDAS 1-6 mft. Discussion: dental caries is present from the first year in 58.8% of children, this is twice the amount reported for Colombia and for the same age (29.3%). Conclusion: the findings highlight the need to design comprehensive strategies for controlling the disease. Such strategies should include oral health in the early policies and programs dealing with early childhood.
