Pasado, presente y futuro de la cariología

Presentamos una breve revisión de la evolución de los conceptos asociados a la epidemiología, diagnóstico, etiología y tratamiento de la caries para proveer una actualización y orientación a los profesionales odontológicos. El término caries incluye la patología y su signo clínico. La patología involucra una disbiosis del biofilm normal bucal que responde de manera dinámica a la dieta rica en azúcares, metabolizando ácidos que generan la lesión de caries. Actualmente el diagnóstico comienza con la evaluación del riesgo cariogénico seguido de la detección de lesiones y la evaluación de su actividad. Para el tratamiento se indican aquellas intervenciones que permiten el control de la actividad del biofilm y recuperar los tejidos dentarios dañados mediante intervención mínima. En el futuro, intervenciones que reduzcan el consumo de azúcar, unido al conocimiento del microbioma, al uso de inteligencia artificial y uso de materiales biomiméticos permitirán un manejo personalizado para mantener y recuperar la salud oral individual. Finalmente, para trasladar los avances científicos de la cariología a la práctica clínica se requieren urgentes cambios en la educación y el contexto en que luego trabaja un profesional odontológico.

We present a brief review of the evolution of the concepts associated with the epidemiology, diagnosis, etiology and treatment of caries, to provide an update and orientation for dental professionals. The term "caries" includes the disease and its clinical sign. The disease involves a dysbiosis of the normal oral biofilm that responds dynamically to a sugar-rich diet, metabolizing acids that result in caries lesions. Currently, the diagnosis begins with the evaluation of cariogenic risk, followed by the detection of lesions and the evaluation of their activity. For the treatment, interventions allowing the control of biofilm activity and the recovery of damaged dental tissues through minimal intervention are indicated. In the future, interventions reducing sugar consumption, together with the knowledge of the microbiome, the use of artificial intelligence and the use of biomimetic materials will allow for a personalized management to maintain and recover individual oral health. Finally, to transfer the scientific advances made in cariology to the clinical practice, urgent changes are required in education and in the context in which the dental professional works.

Reparación de defecto localizado en restauración de amalgama como tratamiento de mínima intervención en cariología / Repair of a localized defect in a restoration with amalgam filling as minimal intervention treatment in cariology

Introducción: La reparación de restauraciones ha sido estudiada desde muy recientemente, pero a pesar de haber demostrado efectividad y mejoras en la terapéutica de la caries dental, aún tiene seguidores y detractores, lo que justifica la necesidad de estudios que sigan avalando tales prácticas. Objetivo: Describir, a través de la presentación de un caso, la reparación de un defecto localizado en una restauración de amalgama como tratamiento de mínima intervención en cariología. Presentación del caso: Paciente femenina de 16 años con antecedentes de salud acude a consulta refiriendo una pequeña fractura de restauración en diente 4.6 desde hace varias semanas. La regularización del defecto en la restauración, la mínima preparación cavitaria, la eliminación del fragmento de la base intermedia, la protección del complejo dentino-pulpar y el llenado de la cavidad resultante, fueron los primeros pasos de una técnica que se cumplimentó luego del pulido final de la interface tejido dentario-restauración y se evolucionó cinco años después. Se evidenció el estado y presencia de la reparación de la restauración realizada, sin fracturas añadidas, microfiltraciones, sintomatologías, desplazamientos ni pérdidas de la continuidad. Conclusiones: La reparación del defecto localizado de amalgama se realizó con el fin de preservar los tejidos dentarios no afectados como lo dicta la mínima intervención en cariología. Cinco años más tarde, la evolución evidencia una práctica que se tradujo en resultados satisfactorios e incremento de la calidad de vida de la paciente(AU)

Introduction: Restoration repair has been studied recently; but, even when it has demonstrated effectiveness and improvements in the therapy of dental caries, it still has followers and detractors that justify the need for studies that continue supporting such practices. Objective: To describe, through a case presentation, the repair of a defect located in a restoration with amalgam filling as minimal intervention treatment in cariology. Case presentation: Sixteen-year-old female patient with health history that went to the clinic reporting a small fracture of a restoration performed in tooth 4.6 several weeks ago. The regularization of the defect in the restoration, minimum cavity preparation, elimination of the fragment of the intermediate base, protection of the dentin-pulp complex, and filling of the resulting cavity were the first steps of a technique that was completed after the final polishing of the dental tissue/restoration interface that was evolved five years later. The status and presence of the restoration repair performed without added fractures, microfiltration, symptomatology, displacement or loss of continuity was evidenced. Conclusions: The repair of the localized defect in a restoration with amalgam filling was performed with the aim of preserving the unaffected dental tissues as dictated by minimal intervention in cariology. Five years later, the patient´s evolution shows a practice that resulted in satisfactory results and an increase in the patient's quality of life(AU)

Diagnóstico terapéutico para la atención de pacientes con caries dental / Therapeutic diagnosis for the care of patients with dental caries

La caries dental es tan antigua como la humanidad misma, es considerada por la Organización Mundial de la Salud como el primer problema de salud bucal, su incremento se ha asociado al desarrollo social y a las variaciones en los hábitos dietéticos de las poblaciones. En estudios realizados en los últimos años, se ha determinado una tendencia a la disminución de esta enfermedad. El problema fundamental en el diagnóstico y tratamiento de la caries dental es la decisión de cuándo y cómo obturar un diente afectado por caries. El objetivo primario es ampliar la visión sobre las posibilidades terapéuticas y profundizar en los conocimientos teóricos y prácticos sobre los tratamientos preventivos, curativos no invasivos e invasivos utilizados contra la caries dental. Se realizó una revisión bibliográfica de textos impresos y búsqueda en internet sobre caries dental, frecuencia y conducta adecuada por parte los estomatólogos generales. Se concluye que todo estomatólogo general, debe conocer la importancia de la promoción y la prevención permanente en los pacientes para evitar las caries dentales, así como las indicaciones, técnica de empleo y los requisitos para aplicar en la práctica diaria, los materiales restaurativos(AU)

Dental caries is as old as human race, it is considered by the World Health Organization as the first oral health problem, its increase has been associated with social development and variations in dietary habits of populations. In studies carried out in recent years, a tendency to decrease this disease has been determined. The fundamental problem in the diagnosis and treatment of dental caries is the decision of when and how to seal a tooth affected by caries. The primary objective is to broaden the vision of the therapeutic possibilities and to deepen the theoretical and practical knowledge about preventive, non-invasive and invasive curative treatments used against dental caries. A literature review of printed texts and internet search on dental caries, frequency and appropriate behavior of general stomatologists was carried out. It is concluded that every general stomatologist should know the importance of the promotion and permanent prevention in patients to avoid tooth decay, as well as the indications, technique of use and requirements to apply restorative materials in daily practice.

RESUMEN: Objetivo: determinar los contenidos impartidos en cariología, su aplicación clínica y metodología educativa empleada, en las escuelas dentales chilenas de pregrado. Método: Se efectuó un estudio de corte transversal, en una muestra por conveniencia de docentes de cariología y/o asignaturas relacionadas con cariología en 23 de 29 escuelas de odontología chilenas (año 2015), n=13 acreditadas ante la Comisión Nacional de Acreditación y n=10 de 16 no acreditadas. Se envió un cuestionario de 55 preguntas por vía electrónica, basado en los dominios propuestos por la Asociación para la Educación Dental Europea. El cuestionario fue sometido al análisis y evaluación previa de contenido y lenguaje por un comité de expertos, los resultados fueron tabulados y analizados utilizando STATA v14.2. Resultados: La tasa de respuesta del cuestionario fue de 86,95%. En promedio el 70% de los contenidos encuestados son impartidos, de ellos, el 65% se impartieron en clases teóricas, el 14% en práctica de laboratorio y se realizó aplicación clínica en el 24% de los contenidos impartidos. Conclusiones: La actual enseñanza de la cariología en las escuelas dentales chilenas es alta en contenidos teóricos, los que mayoritariamente no se imparten a través de práctica de laboratorio y la aplicación clínica de los contenidos desarrollados es escasa.

ABSTRACT: The objective: was to determine the current contents of cariology taught, its clinical application and educational methodology used in Chilean undergraduate dental schools. Materials and Method: A cross-sectional study was carried out in a convenience sample of cariology teachers and/or teachers of cariology-related subjects belonging to 23 of the 29 Chilean Dental Schools (year 2015), including n=13 out of 13 schools accredited by the National Accreditation Commission, and n=10 out of 16 non-accredited schools. A questionnaire of 55 questions was sent electronically, based on the domains proposed by the Association for European Dental Education (ADEE). The survey was subjected to prior analysis and evaluation of content and language by a panel of experts, the results were tabulated and analyzed using STATA v14.2. Results: The response rate o was 86.95%. On average, 70% of the contents surveyed are taught, of which 65% were taught in didactic classes, 14% were in laboratory practice and 24% were taught in the clinical setting. Conclusions: The current teaching of cariology in chilean dental schools includes a large number of subjects taught mainly in didactic settings, with less in the laboratory practice, while the clinical application of the contents developed is scarce.

Cariology Curriculum in Chilean Universities

ABSTRACT: Aim: To describe the current state of undergraduate Cariology teaching in Chilean universities. Material and Methods: A previously content-validated questionnaire was used to conduct a cross-sectional study including all private/public universities. Statistical analysis was performed determining frecuency distributions of categorical variables with the Stata Data Analysis and Statistical Software 13.1®. Results: Cariology is a key issue in undergraduate education, and in most universities, is taught as key axis of courses, in various departments, for more than one year. Consistency was found in Cariology topics taught. The clinical threshold for surgical treatment is roughly divided into thirds (33.3% enamel microcavitation, 38.9% underlying shadow and 27.8% dentin cavity), no university indicated operative treatment for non cavitated lesions. Radiographic threshold for surgical treatment is the external dentinal third (66.7%). Conclusions: Answers revealed a mix of traditional and modern Cariology concepts. Depite some encouraging results, half of Chilean universities considered that Cariology is not appropriately implemented and no standardization exists between theoretical teaching and clinical management, nonoperative management is not properly clinically implemented, students are evaluated for tissue damage restoration and resistance to non-invasive philosophy adoption remains.

ABSTRACT: Objective: Development of a minimum set of competencies in Cariology that every dentist graduated from a Dental School in Chile must have. Methodology: Starting from a meeting of scholars from the Universities of Talca and Chile (year 2011), an initial proposal for a curriculum was developed, based on the domains proposed by the European Cariology Curriculum (Schulte, et al, 2011). During 2016, this proposal was discussed through online dialogues and working groups, with the participation of 95.2% of the Chilean dental schools, which resulted in an intermediate document. This document was analyzed, discussed and refined during the Workshop for the Development of a Curriculum of Minimum Competencies in Cariology for Chilean Dental Schools (May 22, 2017, Talca, organized by the Universities of Talca and Chile) with the attendance of representatives from 95.2% of the Chilean dental schools, the Chilean Ministry of Health, Chilean College od Dentists and with the assistance of the professors of Cariology Margherita Fontana and Carlos González-Cabezas (University of Michigan, Ann Arbor, USA). Each working group revised the document and provided feedback, which was incorporated in the final document by an advisory committee, elected on the day of the workshop, including the authors of the present article. Results: The Cariology Curriculum was organized in 5 Domains: 1. Basic knowledge; 2. Risk assessment, caries diagnosis and caries lesion detection; 3. Decision-making and non-operative preventive treatment; 4. Decision making and operative treatment; and 5. Evidence-based, clinical and public health practice. Operational definitions, main competencies and sub-competencies for each domain were agreed. Sub-competencies were classified into three levels: A: Be competent in; B: Have knowledge about, and C: Be familiar with. The final document was sent to all the participants of the workshop for dissemination in each of the institutions involved. Conclusions: The development of the Competency-based Curriculum in Cariology for undergraduate dental students at Chilean universities was achieved through consensus.

Dental students' and lecturers' perception of the degree of difficulty of caries detection associated learning topics in Brazil / 보건의료교육평가

PURPOSE: It aimed to explore the degree of difficulty of caries-detection-associated-topics perceived by dental students and lecturers as pedagogical step in the development of learning objects for e-learning. METHODS: A convenience sample comprising ninety-eight subjects from different academic levels (undergraduate/graduate students and pediatric dentistry lecturers) participated. Two spreadsheets (isolated/relative) were created considering key topics in the caries detection process. The isolated evaluation intended to explore each topic in an isolated way, while the relative intended to classify, comparatively, the participants' perceived difficulty per topic. Afterwards, data were analyzed. All values on spreadsheets were combined obtaining the subject's final perception. Associations between the subjects' degree of the perceived difficulty and academic level were estimated. ANOVA was used to determine differences regarding the perception among evaluated topics in distinct groups. RESULTS: Caries histopathology and detection of proximal carious lesions were the topics perceived as the most difficult in the process of caries detection by both students and lecturers. Differentiation between an extrinsic pigmentation and a brown-spot (caries lesion) as well as differential diagnosis between caries and enamel developmental defects or non-carious lesions were considered as more difficult by undergraduates in comparison to graduates/lecturers (regression-coefficient=14.54; Standard Error=3.34; P<0.001 and 8.40, 3.31, and 0.01 respectively). CONCLUSION: Topics as histopathology and detection of proximal caries lesions were identified as the most difficult despite the academic level. However, some topics are differently perceived according to the group. These results are useful for developing pedagogical material, based on the students real learning needs/expectations.

La enseñanza de la cariología en la República Bolivariana de Venezuela. ¿qué se enseña? / Teaching cariology en the republica bolivariana de venezuela. What do we teach?

Este estudio lo consideramos un aporte importante del artículo publicado por Maldonado y cols1 en Acta Odontológica Venezolana en el Vol. 52 Nº 2 del Año 2014, y cuya finalidad es mostrar cómo , cuándo y cuánto se enseña de Cariología en los pregrados de las facultades de odontología de la República Bolivariana de Venezuela. En este nuevo trabajo tenemos como objetivo comparar los contenidos programáticos relacionados con la enseñanza de esa especialidad en esas mismas facultades. Vía electrónica se pidió a los decanos de las 8 facultades existentes en el país que enviaran los programas de cariología o en su defecto todos aquellos cuyos objetivos tuvieran una relación directa con cariología. 7 facultades respondieron. Los contenidos programáticos se compararon con una modificación de los analizados por Schulte y cols 2. Se analizaron 45 contenidos y la existencia de ellos osciló entre 4 y 38. En algunas facultades la misma información la dictan varias cátedras en diferentes períodos académicos. Se concluye que es necesaria la estandarización de la enseñanza de cariología en las facultades de odontología de la República Bolivariana de Venezuela...

The deans of all 8 dental schools in the República Bolivariana de Venezuela were contacted to obtain information in regards to the objectives or educational contents in cariology offered in their curricula. One school did not respond. The programs were compared to a list of 45 subjects, and their existence ranged from 4 to 38. Only 2 schools have a formal program in cariology, the remaining 5 teach the cariology contents through different departments, being the most commons operative dentistry and periodontics. In some schools, the same information in offered by 3 or 4 departments. In conclusion, it is mandatory to standardize the cariology teaching in the Venezuelan dental schools...

Effects of various toothpastes on remineralization of white spot lesions / 대한치과교정학회지

OBJECTIVE: The purpose of this in vitro study was to examine the effects of fluoridated, casein phosphopeptide.amorphous calcium phosphate complex (CPP-ACP)-containing, and functionalized beta-tricalcium phosphate (fTCP)-containing toothpastes on remineralization of white spot lesions (WSLs) by using Quantitative light-induced fluorescence (QLF-D) Biluminator(TM) 2. METHODS: Forty-eight premolars, extracted for orthodontic reasons from 12 patients, with artificially induced WSLs were randomly and equally assigned to four treatment groups: fluoride (1,000 ppm), CPP-ACP, fTCP (with sodium fluoride), and control (deionized water) groups. Specimens were treated twice daily for 2 weeks and stored in saliva solution (1:1 mixture of artificial and human stimulated saliva) otherwise. QLF-D Biluminator(TM) 2 was used to measure changes in fluorescence, indicating alterations in the mineral contents of the WSLs, immediately before and after the 2 weeks of treatment. RESULTS: Fluorescence greatly increased in the fTCP and CPP-ACP groups compared with the fluoride and control groups, which did not show significant differences. CONCLUSIONS: fTCP- and CPP-ACP-containing toothpastes seem to be more effective in reducing WSLs than 1,000-ppm fluoride-containing toothpastes.

Este estudio se realizó con el objetivo de conocer la forma en que se enseña cariología en las ocho facultades de la República Bolivariana de Venezuela. Vía internet se remitió un cuestionario a los decanos de las 5 facultades públicas y 3 privadas. Ellos decidieron que cátedras, departamentos o profesores las analizarían. Todas las facultades respondieron. Se encontró que 4 poseen un programa específico de cariología. El número de cátedras o departamentos responsables de su enseñanza osciló entre 2 y 5 cátedras o 1 y 4 departamentos. En 7 facultades los contenidos teóricos se dictan a partir del segundo año, en la restante, en el primer año. En 4 existe una preclínica. En una de ellas, el entrenamiento clínico en cariología comienza el primer año y abarca los cinco años de la carrera en el resto varía de cuatro años a un semestre. Las lesiones cervicales no cariosas se incluyen en el programa de cariología en 6 facultades, y los defectos del desarrollo de la estructura dentaria en 5. En relación a la creación de un currículo común para las facultades de la nación venezolana así como para el área andina o Iberoamérica no se determinó consenso en todas las opciones.

In order to get acquainted how cariology for undergraduate is taught at all 8 dental schools in the República Bolivariana de Venezuela, a questionnaire was send to the deans. All schools responded to the request for information. The results indicated that 4 schools have a specific curriculum in cariology. The academic units involved oscillate between 2 and 5 cathedras or 1 to 5 departments. Theoretical education is delivered by all schools, 7 of them begin it at the second academic year, and one considers it all along the 5 years undergraduate training. In regards to a common cariology curriculum for the country, spanish speaking Latinamerican countries, or the Andean countries no consensus was detected.

Patrón de caries dental en indígenas residentes en corozal, maniapure, Estado Bolívar, Venezuela / Dental caries pattern in indigenous residing in corozal, maniapure, Bolívar State, Venezuela

Evaluar el patrón de caries dental en indígenas residentes en la comunidad de Corozal, Maniapure, Estado Bolívar, Este es un estudio descriptivo y transversal del status de caries dental en indígenas Panares que residen en Corozal, comunidad ubicada en la región de Maniapure, Municipio Cedeño del Estado Bolívar, Venezuela, realizado durante el año 2011. La edad de los sujetos evaluados oscilo entre 2 y 60 años de edad (n= 31), el examen clínico fue realizado por dos estudiantes de odontología previamente calibrados usando los criterios reportados por Radike (1972), modificado por Acevedo et al., (2005). El examen clínico se llevó a cabo con el explorador N°23, espejo bucal N°5 y luz natural. Los resultados se analizaron mediante el test no paramétrico de la U de Mann-Whitney y Kruskal-Wallis. El 100% de los sujetos evaluados estaban afectados por la caries dental. No obstante, de las 3.682 superficies dentarias evaluadas 3.016 se encontraban libres de la enfermedad (81,9%) y 306 estaban afectados por la caries dental (8,3%). Con respecto a la severidad de las lesiones, las no cavitadas fueron las menos frecuentes (3,8%), mientras que el 96,1% tenían al menos un signo de cavitación. De las lesiones cavitadas en la dentición permanente el 62,2% correspondían a lesiones con micro-cavitación en el esmalte, 7,3% fueron lesiones que abarcaban el 50% de la estructura dentaria sin compromiso pulpar y solo 0,5% presentaron compromiso pulpar. Por el contrario, en la dentición primaria el 69.2% de las lesiones presentó compromiso del órgano dentino-pulpar, de las cuales el 6.5% correspondían a cavidades que abarcaban el 50% de la estructura dentaria con compromiso pulpar, 36,8% con destrucción total de la estructura coronaria y 25,9% de restos radiculares.

The aim of this study was to evaluate the epidemiological status of dental caries in Indigenous residing in Corazal, Maniapure, Bolivar State, Venezuela. A cross-sectional study of dental caries condition in indigenous Panare residing in Corozal, community located in Maniapure, Cedeño Municipality, Bolivar State, Venezuela was undertaken in 2011. Subjects from 2 to 60 years of age (N=31) allow to be examined by two dental students previously calibrate using the criteria reported by Radike (1972) as modified by Acevedo et al., (2005). The clinical examination was conducted with explorer N° 23 and dental mirror N°5 using natural light. The results were analyzed using the non-parametric test of U- Mann-Whitney and Kruskal-Wallis. One hundred percent of the evaluated subjects were affected by caries (100%). However, from the total of 3.682 surfaces evaluated, 3.016 were sound (81.9%) and 306 were affected by caries (8.3%). From the total of caries lesion detected the non-cavitate lesion were the least frequent (3.8%) and 96.1% have at least one sign of cavitations. From the cavitated lesion in the permanent dentition 62.2% of lesions showed early enamel breakdown, 17.3% were to lesion that cover 50% of the tooth surface without reaching the pulp and only 0,5 % of the lesion had reach the pulp. In contrast, in the primary dentition 69.2% of the cavities advanced into the pulp. From this group 6.5% were cavities that cover 50% of tooth surface and reach the pulp, 38.6% showed complete destruction of the crown and 25.9% corresponded to remaining root. The mean DMFS and defs were 17.08±26.18 and 5.70±12.61 respectively. The DMFS in the female group (29.07±32.06) was significantly higher as compared to the male (6.75±6.51) (p=0.001), in contrast the defs was higher in the males (12.40± 14.52) as compare to the female (5.63±6.63) (p=0.012).

Prevalence of malocclusion and its relationship with caries among school children aged 11 - 15 years in southern India / 대한치과교정학회지

OBJECTIVE: To assess the prevalence of malocclusion and its relationship with dental caries among school children in southern India. METHODS: This cross-sectional study included 1,800 students aged 11 - 15 years whose Dental Aesthetic Index (DAI) and dentition status were recorded and analyzed. The chi-square test, ANOVA, and Spearman's correlation tests were carried out. RESULTS: The mean DAI score +/- the standard deviation was 18.61 +/- 6.1. Approximately 85% of the students (83.0% males, 86.8% females) had DAI scores of 35, which suggested very severe or handicapping malocclusion requiring mandatory treatment. The mean decayed, missing, filled teeth (DMFT) was 2.28 +/- 1.47. A DMFT of > 0 was observed in 91.8% of the study subjects. Children with a DAI score of > 35 were found to have significantly (p < 0.001) higher caries experience as compared to other children. Moreover, the DAI scores showed a significant correlation with the mean DMFT scores (r = 0.368, p < 0.05). CONCLUSIONS: A positive correlation was found between the severity of malocclusion and dental caries.

The effect of silver ion-releasing elastomers on mutans streptococci in dental plaque / 대한치과교정학회지

OBJECTIVE: The purpose of this study was to investigate the antimicrobial effect of silverized elastomers on mutans streptococci in dental plaque. METHODS: Forty patients undergoing orthodontic treatment were randomly placed into 1 of 2 groups. We examined the maxillary right and left central incisors and premolars, and the mandibular right and left canines of all participants. We ligated the right maxillary and left mandibular teeth of the participants in group 1 with silverized elastomers and ligated their contralateral teeth with conventional elastomers. We ligated the left maxillary teeth and right mandibular teeth of group 2 participants with silverized elastomers. Each participant visited the clinic 4 times at 3-week intervals. We applied the elastomers to the teeth on one side of each patient's mouth during their first visit. During the second visit, the elastomers were removed for microbiological analysis and replaced with steel ligatures. During the third visit, we used silverized elastomers to ligate the teeth contralateral to those treated on the first visit. The elastomers were removed during the fourth visit, and microbiological analyses were performed. We compared the quantity of bacteria on silverized and conventional elastomers at the 0.05 level of significance. RESULTS: The percentage of mutans streptococci was not significantly different in cultures of dental plaque from the silverized and the conventional elastomers (p > 0.05). CONCLUSIONS: There was no significant difference between the antimicrobial effect of the silverized elastomers and that of the conventional elastomers.

Bacteriostatic effect of copaiba oil (Copaifera officinalis) against Streptococcus mutans

This study evaluated the inhibitory activity of copaiba oil (Copaifera officinalis against the cariogenic microorganism, Streptococcus mutans. For such purpose, a minimum inhibition concentration test of copaiba oil against S. mutans was performed, using the serial dilution in broth technique, with a negative control, a positive control (0.12 percent chlorhexidine) and a 10 percent copaíba oil solution as a test. A minimum bactericidal concentration test with tubes presenting microbial inhibition was also conduced. In the minimum inhibitory concentration test, copaiba oil showed inhibition of bacterial growth at all concentrations tested up to 0.78 µL/mL of the 10 percent copaiba oil solution in the broth. In addition, the negative control had no inhibition, and the 0.12 percent chlorhexidine solution was effective up to 6.25 µL/mL in the broth. Copaiba oil showed a bacteriostatic activity against S. mutans at low concentrations, and could be a an option of phytotherapic agent to be used against cariogenic bacteria in the prevention of caries disease.
