Abstract This trial-based economic evaluation aimed to estimate the incremental cost of implementing an active learning strategy (theoretical-practical workshop) to substitute the didactic lecture as the sole method for students training in caries detection. We also provided a budget impact analysis and explored the composition of costs related to the activity. Data from the coordinating centre of a multicentre randomized and controlled study (IuSTC01) was analyzed as the first part of our main economic analysis plan. The perspective of the educational provider (the institution implementing the activity) was considered, and an immediate time horizon was adopted. All used resources were valued in Brazilian Real by adopting a microcosting strategy. Costs for each strategy were estimated and converted into international dollars. The incremental Cost per student and the total cost of implementing the complete teaching strategy for 80 students were calculated. Monte Carlo simulations were used to estimate the uncertainties. The incremental Cost estimated for the workshop implementation would be $7.93 per student (interquartile range (IQR): $7.8–8.1), and the total cost of the teaching activity would be $684 (IQR:672–696). The laboratory training comprised more than 50% of the total amount spent, and a higher percentage of this value was related to human resources costs (72%). Saving 40% of the costs could be expected for the next rounds of activities in the institution, assuming no need for additional preparation of didactic materials and tutor training. A modest incremental cost per student and an acceptable organizational budget impact should be expected for the institution when including active learning training in caries detection for undergraduate students, mainly related to the human resources involved. trialbased trial based theoreticalpractical theoretical practical IuSTC01 IuSTC (IuSTC01 plan considered adopted dollars 8 calculated uncertainties 793 7 93 $7.9 interquartile IQR (IQR) $7.8–8.1, 7881 $7.8–8.1 , 1 $7.8–8.1) 684 $68 IQR672–696.

ABSTRACT Objective: To assess the relationship between celiac disease and the prevalence of dental caries in children and adolescents and also evaluate if dental enamel defects in celiac children predispose to dental caries. Material and Methods: Searches were performed in the following databases: PubMed, Scopus, Cochrane Library, Latin American and Caribbean Literature on Health Sciences, and OpenGrey. The risk of bias was assessed using the Newcastle-Ottawa Scale. DMFT/dmft and DMFS/dmfs data of observational studies that compared the prevalence of caries between children and adolescents with celiac disease and healthy individuals. Meta-analysis was performed using a random effects model. Heterogeneity between studies was estimated using Cochran’s Q test, and inconsistency was measured using I2 statistics. Results: Of the 121 studies retrieved, 17 were selected, and 12 were included in the meta-analysis. The prevalence of caries in the primary dentition (dmft) did not differ between celiac patients and controls [SMD = -0.35; 95% CI (-0.83; 0.13); p = 0,15; I2 = 89%]. There was also no difference in the prevalence of caries in permanent teeth (DMFT) between groups [SMD = -0.44; 95% CI (-1.02; 0.14); p = 0.14; I2 = 95%]. Conclusion: Celiac disease is not a determinant factor in the development of dental caries in children and adolescents compared to the control group.

Abstract Background Hall technique (HT) has been indicated for teeth with dentinal caries lesion; however, extensive cavities, with more than two surfaces still seem challenging for restorative treatment in pediatric dentistry, resulting in a higher failure rate and an increased need for retreatment. Objectives To compare the survival rate of the Hall technique preformed metal crown (HT) with resin composite restoration (RC) for multi-surface cavitated caries lesions in primary molars. Methodology In this multicenter two-arm randomized clinical trial, children between 4 and 9 years of age with at least one primary molar with cavitated caries lesion involving more than two surfaces, including one buccal or palatal/lingual surface, were selected from 17 Brazilian cities. A total of 364 teeth were allocated into two groups: (1) teeth treated with selective caries removal and RC and (2) treated with the HT. The survival rate was assessed at 6 and 12 months after the interventions. Survival analysis was performed with the Kaplan‒Meier method. Cox regression was used to determine the influence of explanatory variables on the survival rate (α=5%). Results After 12 months, 292 teeth were re-evaluated. A total of 358 teeth were re-evaluated at least once during the study and included in the survival analysis. The HT (87.8%) resulted in a higher survival rate than RC restoration (75.7%) (p=0.004). Conclusion HT has a higher survival rate than RC as a treatment for multi-surface cavitated caries lesions in primary teeth.

ABSTRACT Objective: To investigate whether the dimensions of cavitated dentin carious lesions on the occlusoproximal surfaces of primary teeth could predict the location of cement-enamel junction (CEJ). Material and Methods: Two hundred extracted primary molars were selected and digital images were obtained. The teeth were set in arch models for clinical measurement. The cervical-occlusal (CO) and buccal-lingual/palatal (BL/P) cavities’ dimensions were obtained by digital (Image J) and clinical (periodontal millimeter probe) assessments. The cervical margin location was also determined. The thresholds (cut-off points) were determined by sensitivity, specificity and the areas under the receiver operating characteristics curves (Az) for the two methods. Pearson's correlation coefficient was used to investigate the correlation between clinical and digital measurements. Logistic regression analysis was performed to evaluate the association between the dimensions and cervical margin location. Results: There was a strong correlation between methods for all measurements (CO: r=0.90, VL/P: r=0.95). Cavities with BL/P distance higher than 4.5 mm and CO dimension higher than 3.5 mm had a lower chance of presenting the cervical limit above the CEJ, irrespective of the measurement method. Conclusion: CO and VL/P dimensions could be used to predict the CEJ location and, ultimately, as a clinical parameter for restorative decision-making. Objective cementenamel cement enamel CEJ. .

ABSTRACT In pediatric dentistry, restorative treatment requires a material with good mechanical properties, ease of handling, and usability. For the restoration of deciduous teeth, colored compomers are an alternative material for motivating children in dental treatment and, consequently, behavior management. This study aimed to provide information about colored compomers by presenting a case of restoration in a deciduous molar with a five-year follow-up. Additionally, the study highlights the child’s motivation toward dental treatment and oral care, thus offering an alternative to other restorative materials for clinicians to consider. The treatment plan for tooth 75 was selective removal of decayed tissue and restoration with compomer blue- colored Twinkly Star. The restoration was performed without anesthesia under relative isolation following the clinical protocol recommended by the manufacturer. As a result, it was observed that the restoration in colored Twinky Star compomer remained aesthetically and functionally satisfactory after five years. In addition, it was favorable for the child’s collaboration in dental treatment. It is concluded that colored Twinky Star compomer can be a viable alternative for restoring deciduous teeth, contributing to children’s dental treatment and oral care motivation. dentistry properties handling usability teeth consequently management fiveyear year followup. followup follow up. up follow-up Additionally childs child s consider 7 blue manufacturer result years addition childrens

Abstract There are many glass ionomer cements available on the Brazilian market for Atraumatic Restorative Treatment (ART), however, there is still a gap in the literature regarding their cost-effectiveness. Objectives To evaluate the influence of restorative materials (Ketac Molar, 3M ESPE; and Vitro Molar, Nova DFL) in the two-year survival rate and cost-effectiveness of occluso-proximal ART restorations in primary molars. Methodology A total of 117 children (aged four to eight years) with at least one occluso-proximal carious lesion in primary molars were selected and randomly divided in treatment groups (KM or VM) in this parallel randomized controlled trial. Treatments followed ART premises and were conducted in public schools by trained operators in Barueri, Brazil. A trained, calibrated, and blinded examiner performed the evaluations after two, six, 12, and 24 months (k=0.92). Kaplan-Meier survival analysis was used to estimate restoration survival and Cox regression was used to test the association with clinical factors (α=5%). For cost analysis, material and professional costs were considered. Monte Carlo analysis was used to generate a cost-effectiveness plane and bootstrapping was used to compare material costs over the years. Results The overall survival rate was 36.9% after two years (48.6% for KM and 25.4% for VM). Restorations with VM failed more than those with KM (HR=1.70; 95% CI=1.06–2.73; p=0.027). VM presented lower initial cost, but no difference was observed between groups considering the two-year incremental cost. Conclusion After a two-year evaluation, KM proved to be a better option than VM for occluso-proximal ART restorations in primary molars. ClinicalTrials.gov: NCT02267720

RESUMO O tratamento de lesões cavitadas de cárie em dentes decíduos anteriores é uma demanda frequente na clínica de odontopediatria, visto que o controle da doença na primeira infância ainda se apresenta como um desafio interfatorial nos cuidados em saúde infantil. Enquanto a evidência científica nos princípios minimamente invasivos de abordagem em Odontologia apresenta-se em nível crescente, as alternativas para tratamento restaurador em dentes decíduos anteriores ainda esbarram na baixa disponibilidade de relatos que associem a mínima intervenção às necessidades estéticas inerentes ao tratamento. Assim, este artigo apresenta uma série de casos em que as restaurações diretas em resina composta, sem a remoção de tecido cariado utilizando matrizes de polivinila foram alternativas de tratamento para lesões de cárie moderadas e severas em dentes decíduos anteriores. Observou-se que o uso desse artefato auxiliou a reabilitação dos elementos dentários comprometidos com rapidez e resultado satisfatório, sugerindo que essa é uma abordagem adequada para aplicação em Odontopediatria, já que oferece resistência, durabilidade, além de proporcionar estética e funcionalidade, apresenta menor custo e agilidade na medida que dispensa a fase laboratorial.

ABSTRACT The treatment of cavity carious lesions in anterior deciduous teeth is a frequent demand in the pediatric dentistry clinic, since the control of the disease in early childhood still presents itself as an inter-factor challenge in child health care. While the scientific evidence on the minimally invasive principles of approach in Dentistry is presented at an increasing level, the alternatives for restorative treatment in anterior deciduous teeth still face the low availability of reports that associate minimal intervention with the aesthetic needs inherent to the treatment. Thus, this article presents a series of cases in which direct restorations in composite resin, without removing carious tissue using polyvinyl matrices, were treatment alternatives for moderate and severe caries lesions in anterior deciduous teeth. It was observed, therefore, that the use of this artifact helped the rehabilitation of compromised dental elements with speed and satisfactory 50 result, suggesting that this is an appropriate approach for application in Pediatric Dentistry, 51 since it offers resistance, durability, besides providing aesthetics and functionality, it presents lower cost and agility as it eliminates the laboratory phase.

RESUMO Os dentes supranumerários representam um desafio para clínicos e odontopediatras quanto ao diagnóstico e tratamento. São assintomáticos, podendo gerar atraso na dentição permanente, alteração do crescimento ósseo e posicionamento ectópico. Assim, o presente trabalho teve como objetivo apresentar um relato de caso de remoção cirúrgica de dentes supranumerários na região anterior da maxila de um paciente infantil, em ambiente hospitalar sob anestesia geral. O paciente do sexo feminino, 6 anos, compareceu ao consultório apresentando como queixa a presença de um dente “estranho” na região anterior. Foram realizados o exame clínico e exames de imagem com a confirmação do diagnóstico de dentes supranumerários na região do incisivo central superior direito (11) e do incisivo central superior esquerdo (21). Tendo em vista o histórico odontológico e comportamental da paciente, optou-se em realizar o tratamento cirúrgico em ambiente hospitalar, auxiliado por equipe multidisciplinar. Dessa forma, ao final dos procedimentos foi verificado que o atendimento em ambiente hospitalar é viável para maior conforto do paciente não colaborador.

ABSTRACT The diagnosis and treatment of supernumerary teeth pose a challenge for dental clinicians and pediatric dentists. These teeth are asymptomatic and may cause the delayed eruption of the permanent dentition, altered bone growth and ectopic positioning. This paper reports a case of the surgical removal of supernumerary teeth in the anterior region of the maxilla of a child under general anesthesia in a hospital setting. A six-year-old female patient visited a private dental office in the city of Garanhuns, Brazil, accompanied by her mother, who reported a tooth with a “strange shape” in the anterior region as the main complaint and also reported that her daughter’s first dental experience was negative. The clinical examination and imaging tests were performed under general anesthesia to confirm the diagnosis. In view of the patient’s dental and behavioral history, surgical treatment was performed in a hospital setting and assisted by a multidisciplinary team. Care in the hospital setting was found to be feasible, providing greater comfort for uncooperative patients.

RESUMO Objetivo: determinar a prevalência de anquiloglossia em recém-nascidos e verificar os fatores que interferem na amamentação exclusiva e geram dificuldades na amamentação. Métodos: trata-se de um estudo observacional longitudinal, realizado em maternidade pública do município de Teresina, PI, Brasil. A amostra foi composta por 397 pares (mães e bebês). Para o diagnóstico de anquiloglossia foi realizada a parte I do Protocolo de Avaliação do Frênulo da Língua com Escores para Bebês. Após seis meses do nascimento, as mães foram entrevistadas e responderam questões sobre indicação e realização de frenotomia e tempo de aleitamento materno. Foram realizados análise descritiva dos dados, teste Qui-quadrado e Regressão de Poisson bivariada e multivariada (p<0,05). Resultados: a prevalência de anquiloglossia foi de 4,3% (n=17). A taxa de retorno para segundo momento da pesquisa foi de 70,8% (n=281). Das crianças examinadas, 14 foram indicadas para frenotomia lingual, mas apenas uma foi submetida ao procedimento. Crianças com anquiloglossia tiveram tempo de amamentação exclusiva igual ao de crianças com frênulo da língua normal (valor de p=0,876). Anquiloglossia não apresentou associação com dificuldade de amamentação (RP=1,0 IC95%0,8-1,1, valor de p=0,441) ou constituiu fator para não amamentação exclusiva por 6 meses (RP=1,1 IC95%0,9-1,2, valor de p=0,390). Conclusões: a prevalência da anquiloglossia na população estudada foi de 4,3% e o uso de mamadeira no primeiro mês de vida e dificuldades de amamentação foram considerados como fatores impeditivos para amamentação exclusiva.

ABSTRACT Objective: to determine the prevalence of ankyloglossia in neonates and verify factors that interfere with exclusive breastfeeding and cause difficulties in breastfeeding. Methods: an observational longitudinal study conducted at a public maternity hospital in Teresina, Piauí, Brazil. The sample comprised 397 mother-child pairs. Ankyloglossia was diagnosed with the part I of the Baby Lingual Frenulum Assessment Protocol with Scores. Six months after the children were born, the mothers were interviewed and answered questions on the indication and performance of frenotomy and time of breastfeeding. Descriptive analysis of the data, chi-square test and bivariate and multivariate Poisson regression were conducted (p < 0.05). Results: the prevalence of ankyloglossia was 4.3% (n = 17). The attendance rate for the second moment of the research was 70.8% (n = 281). Of the examined children, 14 were indicated for lingual frenotomy, but only one was submitted to the procedure. The time of exclusive breastfeeding of children with ankyloglossia was equal to that of children with a normal lingual frenulum (p-value = 0.876). Ankyloglossia was not associated with breastfeeding difficulties (PR = 1.0 95%CI 0.8-1.1, p-value = 0.441), neither was it a factor for not breastfeeding exclusively for 6 months (PR = 1.1 95%CI 0.9-1.2, p-value = 0.390). Conclusions: the prevalence of ankyloglossia in the studied population was 4.3%. Baby bottle use in the first month of life and breastfeeding difficulties were hindering factors for exclusive breastfeeding.

Resumo Introdução: a avulsão de dentes decíduos é um evento perturbador e inesperado. Descrição: o presente relato descreve o caso clínico de uma criança de três anos que sofreu avulsão e reimplante dos incisivos centrais superiores decíduos no local do acidente. Os responsáveis procuraram atendimento para a criança na Universidade Federal de Minas Gerais após reimplante. Quatro meses depois, a criança sofreu novo trauma e os dentes reimplantados apresentavam mobilidade avançada, reabsorção radicular e fístula. A conduta clínica foi extração e reabilitação com mantenedor estético fixo. Discussão: a literatura descreve duas opções de tratamento para avulsão de incisivos decíduos: o reimplante e o não reimplante. De acordo com revisão sistemática recente, a dificuldade de se obter um consenso sobre a melhor conduta clínica se deve, em parte, à escassez de publicações que apresentem não apenas acompanhamentos com sucesso clínico, mas também com falhas. O reimplante pode ser influenciado por vários fatores. O tempo decorrido entre o reimplante e a contenção, e o novo episódio de trauma, influenciaram negativamente o prognóstico do presente caso, levando ao insucesso. O reimplante de incisivos decí- duos ainda não é um tratamento baseado em evidências. Portanto, essa opção deve ser escolhida com cautela e em situações ideais. Requer monitoramento clínico e radiográfico para constante avaliação do desfecho.

Abstract Introduction: the avulsion of primary teeth is a disturbing and unexpected event. Description: this report describes the clinical case of a three-year-old child who suffered an avulsion and replantation of the primary upper central incisors at the site of the injury. The guardians sought treatment for the child at the Federal University of Minas Gerais after the replantation. Four months later, the child suffered a new trauma and the replanted teeth presented advanced mobility, root resorption and fistula. The clinical conduct was extraction and rehabilitation with a fixed esthetic maintainer. Discussion: the literature describes two treatment options for avulsion of primary incisors: replantation and non-replantation. According to a recent systematic review, the difficulty in obtaining a consensus regarding the best clinical conduct is due, in part, to the scarcity of publications that present not only follow-ups with clinical success, but also with failures. The outcomes of replantation can be influenced by several factors. The time elapsed between replantation and splinting, and the new episode of trauma, negatively influenced the prognosis in the present case, leading to failure. Replantation of primary incisors is not yet evidence-based treatment. Therefore, this option must be chosen with caution and in ideal situations. It requires constant clinical and radiographic monitoring for evaluation of outcomes.

Abstract: This study compared the cost of endodontic treatment in primary teeth involving a technique that does not require root canal instrumentation using antibiotic paste (CTZ) with that of the instrumented technique using iodoform paste (GP). This study is part of a randomized, controlled, parallel arm, noninferiority, 1:1 allocation, blinded (patient) multioperator study of 52 primary incisors of children aged 3 to 6 years with caries lesion and pulp involvement. Each technique was performed according to the creators’ descriptions. The cost was assessed by analyzing the costs of capital, dental supplies, and professional labor according to the time taken to perform the procedure and the CHEERS guidelines were used to report the cost assessment. Endodontic treatment with CTZ had a 58.33% lower execution cost than GP (US$6.73 and US$16.15, respectively). The t-test showed significant differences between groups regarding treatment time and total cost (p < 0.0001). The CTZ technique seems to be more economically viable than GP for endodontic treatment of primary teeth, requiring a shorter treatment time and lower costs.

Resumo Objetivos: estudo transversal analítico, de natureza quantitativa buscou identificar características demográficas, de acesso aos serviços de saúde e de condições de moradia relacionadas à prática alimentar de crianças brasileiras de 12 a 23 meses de vida. Métodos: a partir dos dados da Pesquisa Nacional de Saúde 2013, as práticas alimentares de 2541 crianças brasileiras de 12 a 23 meses, foram analisadas quanto à recomendação de consumo dos grupos alimentares. A análise das características associadas às práticas alimentares foi realizada pela árvore de decisão usando o algoritmo CHAID (Chi-squared Automatic Interaction Detector) e análise de regressão de Poisson ajustada hierarquicamente. As variáveis foram inseridas em modelo hierárquico em níveis distal (demográficas), intermediário (acesso à saúde) e proximal (condições de moradia). Resultados: verificou-se uma alta prevalência no consumo de açúcar (85,5%; IC95%=83,7-87,2) e que crianças que não eram da cor branca (p=0,001), e residiam nas regiões Norte (p<0,001) e Nordeste (p=0,010) do país e em cidades do interior (p<0,001) apresentaram práticas alimentares que não atingem a recomendação de consumo dos distintos grupos alimentares. Conclusão: crianças que não eram da cor branca, residentes no Norte/Nordeste e no interior, áreas de maior vulnerabilidade do país, foram mais propensas à práticas alimentares inadequadas. Medidas para melhorar tais práticas devem abordar as desigualdades socioeconómicas e intervenções de promoção à saúde.

Abstract Objectives: a quantitative analytical cross-sectional study aimed to identify demographic characteristics to access health services and housing conditions in relation to inadequate feeding practices among Brazilian children from 12 to 23 months of age. Methods: the analysis of the feeding practices (consumption of recommended food groups) of 2541 Brazilian children (aged 12-23 months old) was performed using data from the Pesquisa Nacional de Saúde 2013 (National Health Survey). Descriptive and multivariate statistics used the Decision Tree Analysis based on CHAID (Chi-squared Automatic Interaction Detector) algorithm, as well as hierarchically adjusted Poisson regression analyses were performed. The variables were entered in a hierarchical model at distal (demographic), intermediate (access to health) and proximal (housing conditions) levels. Results: the results showed a high prevalence of sugar consumption (85.5%; CI95%=83.7-87.2) and highlighted inadequate feeding practices among non-white children (p=0.001), resident in the North (p<0.001) and Northeast (p=0.010) of Brazil and in towns in the countryside (p<0.001) presented feeding practices that were not recommended for consumption in the food groups. Conclusions: non-white children, who lived in the North and Northeast regions of Brazil and in the countryside, which are known to be more socioeconomically vulnerable, were more likely to experience inadequate feeding practices.

Abstract Objective: To compare retention, preventive effectiveness and longevity of two different high-viscosity glass-ionomer sealants Ketac Molar® and Maxxion R® in the sealing of erupting and out-of-occlusion first permanent molar in children aged 5-7 years. Material and Methods: Children with past caries experience with healthy erupting first permanent molar were included in the study. Teeth 16 and 46 were sealed with Ketac Molar® and teeth 26 and 36 were sealed with Maxxion R®. After 8 months, the retention of sealants was evaluated using the following criteria: total retention; presence of sealant in two thirds of the occlusal surface; presence of sealant in one third of the surface; and total absence of the sealant. Results: Statistical difference between materials was observed, and Ketac Molar® retention was superior to that of Maxxion R® (p<0.05). Regarding the development of caries in sealed first permanent molar, none of the teeth sealed with Ketac Molar® or Maxxion R® developed caries lesion. Conclusion: Ketac Molar® retention is significantly superior to that of Maxxion R®, but the preventive effectiveness in the development of carious lesions is similar for both, which is extremely interesting for the field of public health, since the cost of the material is significantly lower.

RESUMO O objetivo deste trabalho é apresentar um caso de hiperplasia fibrosa inflamatória provocada por irritação crônica decorrente do mau posicionamento dental após trauma. Uma adolescente, 11 anos, foi encaminhada ao Centro de Especialidades Odontológicas, com queixa de que o incisivo central superior não havia erupcionado e em seu lugar havia surgido uma lesão de tecido mole, acarretando mudanças no comportamento da mesma que se tornou mais tímida. Após anamnese e exame clínico, constatou-se a presença do dente 11 em posição bastante vestibularizada, coberto por lesão hiperplásica. Foi realizado o tratamento cirúrgico e o resultado do exame histopatológico revelou que se tratava de hiperplasia fibrosa inflamatória. Durante as consultas para acompanhamento, foi possível observar a melhora no posicionamento do dente em questão e a satisfação da adolescente. Diante da baixa prevalência de hiperplasia fibrosa inflamatória na população infantil, vale ressaltar que o posicionamento do dente, fora do seu alinhamento correto no arco, pode provocar traumas repetidos em mucosa e, com isso, tornar-se fator etiológico para hiperplasia fibrosa inflamatória, acometendo, inclusive, crianças e adolescentes. Assim, o cirurgião dentista deve estar atento para estabelecer um diagnóstico e tratamento clínico oportunos, além do acompanhamento destes casos.

ABSTRACT This paper aims to describe an inflammatory fibrous hyperplasia case caused by chronic irritation due to poor dental positioning after trauma. An 11-year-old female patient was sent to a dental specialty center with the complaint of a soft tissue growth in the place of an unerupted maxillary central incisor, causing her behavioral changes becoming more timid. After anamnesis and clinical examination it was noted that tooth 11 was in a vestibular position, covered with a hyperplastic lesion. Surgical treatment was performed and the histopathological exam revealed inflammatory fibrous hyperplasia. Over the course of the follow-up appointments, it was possible to observe improvement on the mentioned tooth and the patient’s satisfaction. In face of the low prevalence of inflammatory fibrous hyperplasia, it is worth mentioning that the tooth positioning, outside its correct alignment in the arch, can cause repeated trauma to the mucosa, and then turning into etiological factor to inflammatory fibrous hyperplasia, affecting even children and adolescents. Thus, the dentistry must be alert to establish a diagnosis and clinical treatment, in addition to monitoring these cases.

Abstract Objective: To evaluate the antimicrobial action of the CTZ paste in three different proportions by diffusion in agar with the microorganisms: Enterococcus faecalis,Escherichia coli, and Candida albicans. Material and Methods: Three different proportions of antibiotics were tested: GROUP A - CTZ paste in the ratio of 33.33% chloramphenicol + 33.33% tetracycline + 33.33% zinc oxide, mixed with 2 drops of eugenol (1:1:1 ratio); GROUP B - CTZ paste in the proportion of 25% chloramphenicol + 25% tetracycline + 50% zinc oxide, mixed with 2 drops of eugenol (1: 1: 2 ratio); GROUP C - CTZ paste with 13% chloramphenicol + 13% tetracycline + 74% Zinc Oxide, mixed with 2 drops of eugenol (1:1:6 ratio); PC GROUP - Positive Control (0.12% Chlorhexidine); and NC GROUP - Negative Control (0.9% Saline solution). Data were analyzed through descriptive statistics (means and standard deviation). The one-way ANOVA and Tukey’s test were used, with a significance level of 5% Results: No statistical differences for Enterococcus faecalis between groups A, B, and C (p = 0.1986) were found. There were statistical differences for Escherichia coli between groups B and C (p = 0.029), and for Candida albicans between groups A and C (p = 0.006). Groups A, B, and C had significant differences with both Positive and Negative Controls for all the microorganisms Conclusion: The three different ratios of CTZ paste showed antimicrobial efficacy against Enterococcus faecalis,Escherichia coli, and Candida albicans microorganisms.
