Early childhood caries management using fluoride varnish and neutral fluoride gel: a randomized clinical trial.

The aim of this study was to evaluate the clinical efficacy of varnish and neutral fluoride gel in the management of early childhood caries (ECC). A randomized clinical trial was conducted to compare two strategies for ECC management: topical application of neutral fluoride gel (NFG group) and varnish (FV group) every four months for a period of one year. The sample consisted of children between the ages of three and four years, enrolled in public daycare centers. The incidence of ECC between the groups was compared by assessing values (new dmfs) at two levels: d2 when enamel/dentin were affected and d3 when dentin affected. Pearson's Chi-square, Fisher's Exact, Kolmogorov-Smirnov and Mann-Whitney tests were used to compare the incidence and increment of caries between the NFG and FV groups (p<0.05). A total of 240 children were included in this study and 213 children (88.7%) were followed up for 12 months. The incidence of ECC was 24.1% in the GF and 21.0% in the FV groups (p=0.586). The increment of caries in d2mfs was 1.36 (95% CI = 0.83 - 1.89) in the NFG and 1.33 (95% CI = 0.75 - 1.89) in FV (p=0.756) groups. Increment of caries in d3mfs was 1.60 (95% CI = 0.95 - 2.25) in NFG and 1.40 (95% CI = 0.75 - 2.04) in FV (p=0.468). Neutral fluoride gel and fluoride varnish exhibited similar efficacy in the management of ECC after 12 months of follow-up.

ABSTRACT Objective: to evaluate the knowledge of community health workers about the identification of depressive symptoms in the community. Method: this is a qualitative research, conducted in a Primary Health Care Unit in Teresina, Piauí, Brazil, with 15 community health workers. We used the Action-Research method. Data production took place in January and February 2019, through two thematic seminars, guided by the Creative Sensitive Method.The speeches were submitted to thematic analysis. Results: community health workers recognize the depressive symptoms by means of sadness, crying, isolation, anhedonia and loneliness, manifested by individuals. The limitations to this identification, reported by professionals, were difficulty of access to users and families, as well as stigma and prejudice against depression. As for the possibilities, access to information about the theme through the media, dialogue/conversation established between users and professionals, besides access to a support network, were highlighted. Final considerations: we conclude that the recognition, limitations and possibilities of identification of depressive symptoms by these professionals are reflected in the diagnosis, planning and implementation of actions in mental health care in an early and safe way.

Effect of fluoridated water on dental caries and fluorosis in schoolchildren who use fluoridated dentifrice.

This cross-sectional study evaluated the prevalence and severity of dental caries and fluorosis in children and adolescents using fluoridated toothpaste, from areas with and without fluoridated water. Parents of 5-year-old children and 12-year-old adolescents from neighbourhoods that are supplied with and without fluoridated water answered questionnaires for determining socio-economic and demographic characteristics and habits related to oral health. The individuals were examined, and dental caries and fluorosis were measured by dmft/DMFT and TF indexes, respectively. Descriptive, bivariate and logistic regression analyses were performed (p < 0.05). Of 692 participants, 47.7% were 5-year-olds and 52.3% were 12-year-olds. The mean dmft/DMFT in the 5-year-olds/ 12-year-olds from Exposed and Not Exposed fluoridated water groups was 1.53 (± 2.47) and 3.54 (± 4.10) / 1.53 (± 1.81) and 3.54 (± 3.82), respectively. Children (OR = 2.86, 95% CI = 1.71-4.75) and adolescents (OR = 1.95, 95% CI = 1.24-3.05), who did not consume fluoridated water, had greater caries experience. Among adolescents, there was an association between fluoridated water and the prevalence of very mild/mild fluorosis (OR = 5.45, 95% CI: 3.23-9.19) and moderate fluorosis (OR = 11.11, 95% CI = 4.43-27.87). Children and adolescents, who consumed fluoridated water, presented lower prevalence and severity of dental caries compared to those who used only fluoridated toothpaste as the source of fluoride. There is an association between water fluoridation and very mild/mild and moderate fluorosis in adolescents.

Quilombola children and adolescents show high prevalence of developmental defects of enamel. / Crianças e adolescentes quilombolas apresentam alta prevalência de defeitos de desenvolvimento do esmalte.

Teeth with developmental defects of enamel (DDE) have porous and/or uneven enamel, making them more susceptible to the build-up of oral biofilm and development of caries and periodontal diseases. The aim of this cross-sectional study was to determine the prevalence of DDE and associated factors among children and adolescents living in a Quilombola community in the Northeast of Brazil. The study population was census-based and comprised individuals aged three to 14 years. The children's parents/guardians answered a questionnaire devised to collect information on socioeconomic and demographic characteristics, health problems during pregnancy and illnesses during early childhood. DDE was diagnosed using the modified DDE index. The data were analyzed using descriptive statistics and Poisson regression with robust standard errors (p<0.05). A total of 406 individuals were examined. DDE prevalence was 80.5%: 42.2% in deciduous teeth and 61.1% in permanent teeth. There was an association between presence of DDE and age (PR=1.09, 95% CI=1.01-1.17), use of antibiotics during pregnancy (PR=1.14, 95% CI=1.07-1.22) and reported malnutrition during early childhood (PR=1.12; 95% CI=1.03-1.22). The findings reveal high prevalence of DDE among children and adolescents living in the Quilombola community. Associated factors were older age, use of antibiotics during pregnancy and malnutrition during early childhood.

ABSTRACT Objective: To determine in vitro the frequency, shape, type, diameter, and patency of accessory canals in the primary molars pulp chamber floor. Material and Methods: Sixteen healthy primary molars were evaluated by micro-computed tomography and scanning electron microscopy. Descriptive analyses of the frequency, shape (round, oval, or irregular), type (blind, true, or hidden), patency and diameter of the accessory canals were performed. Results: Half of the teeth presented accessory canals, 62.5% of which were located in the upper molars and 37.5% in the lower molars. The most frequent shape was irregular. In three-dimensional analysis, blind accessory canals (12.5%) and with patency (18.7%) of the teeth were observed. The average accessory canal diameter was 51.97 µm (± 26.03 µm). Conclusion: Upper molars showed a higher frequency of accessory canals with larger diameters. The irregular shape was the most frequent. 18.7% of accessory channels showed patency.

Timing of sugar introduction in diet and early childhood caries: a population-based study in preschoolers / Momento de introdução de açúcar na dieta e cárie na primeira infância: um estudo de base populacional em pré-escolares

Abstract Introduction Sugar ingestion is the most important isolated factor related to dental caries. Contact with sugary foods at an early age may represent a risk to the oral health of preschool children. Objective To evaluate the timing of the introduction of sugar in the diet of preschoolers and its association with early childhood caries. Material and method Cross-sectional population-based study with 888 five-year-old preschoolers from public and private schools. Parents answered a questionnaire on sociodemographic data, eating habits and oral health. The variables timing of sugar introduction (>1 year and ≤1 year) and dental caries experience were dichotomized and data were analyzed using descriptive statistics and Poisson regression (p<0.05). Result The introduction of sugar in the diet occurred during the first twelve months of life for 73.8% of preschoolers. There was no association between the timing of sugar introduction and early childhood caries (p>0.05). The interruption of exclusive breastfeeding and low family income increased the prevalence of preschoolers having early contact with sugar by 32% and 23%, respectively (p<0.05). The prevalence of early childhood caries was 42.3% and was associated with a lower level of maternal education, low income, increased frequency of ingestion of candy and the use of nonfluoridated toothpaste (p<0.05). Conclusion The introduction of sugar in the diet occurred during the first year of life in most preschoolers and there was no association with early childhood caries.

A prevalência de cárie na primeira infância foi de 42,3% e esteve associada à menor escolaridade materna, baixa renda, maior frequência de ingestão de doces e uso de dentifrício não fluoretado (p <0,05). Conclusão A introdução de açúcar na dieta ocorreu durante o primeiro ano de vida na maioria dos pré-escolares e não houve associação com cárie na primeira infância.

Dentin Thickness of Pulp Chamber Floor in Primary Molars: Evaluation by Cone-Beam Computed Tomography

ABSTRACT Objective: Use cone-beam computed tomography (CBCT) images to evaluate the dentin thickness of the pulp chamber floor in primary molars. Material and Methods: Cross-sectional study, conducted with CBCT images of teeth of children. Primary molars with preserved pulp chamber floor were included. The dentin thickness of the pulp chamber floor in the primary molars was measured linearly in CBCT cross-sections. Data were descriptively analyzed and the Mann-Whitney test was applied (p<0.05). Results: 27 CBCT exams and 123 primary molars of children aged 4 to 13 years were analyzed; the majority was female (52.0%). In maxillary molars, the median dentin thickness was 1.50 (0.6-2.2) mm in the first and 1.65 (0.6-2.3) mm in the second (p=0.049) molars. In mandibular molars, the median was 1.20 (0.3-1.7) mm in the first and 1.60 (1.0-2.2) mm in the second (p<0.001) molars. Children aged 4 to 8 years showed less dentin thickness (p<0.001). Conclusion: The median dentin thickness of the pulp chamber floor in primary molars was 1.50 mm, ranging from 0.3 to 2.3 mm. Less dentin thickness was associated with younger children, teeth in the mandibular arch, and first molars.

Prevalence of Enamel Defects in Premolars Whose Predecessors Were Treated with Extractions or Antibiotic Paste.

PURPOSE: To determine the prevalence of developmental defects of the enamel (DDE) in premolars whose infected predecessors were submitted to pulp therapy with antibiotic paste or extractions due to pulp necrosis. MATERIALS AND METHODS: A cross-sectional study with a consecutive sample consisting of children and adolescents who presented with fully erupted premolars, was evaluated. Data were collected by dental examinations, in which the modified DDE index was applied. Dental records were evaluated and three groups of premolars were determined according to the clinical history of predecessors: GCTZ: with pulp necrosis and treated with CTZ (chloramphenicol, tetracycline, zinc oxide and eugenol) paste; GE: with pulp necrosis and treated by extraction; GH: healthy and physiologically exfoliated. Descriptive analysis and a logistic regression (p <0.05) were performed. RESULTS: The study included 1017 premolars, DDE was present in 22.5%. Premolars belonging to the GE group presented higher odds of DDE (odds ratio (OR) = 3.52, 95% CI:2.29-5.40) than those of GCTZ group (OR = 2.43, 95% CI:1.51-3.91) and GH group (p <0.01). Enamel defects were more frequent in maxillary premolars (OR = 3.22, 95% CI:1.65-6.27, OR = 3.39, 95% CI:1.67-6.90, OR = 2.90, 95% CI:1.48-5.66 and OR = 3.10, 95% CI:1.54-6.23). CONCLUSIONS: The prevalence of enamel defects was higher in premolars whose predecessors were removed because of necrosis, followed by those treated with CTZ paste and those that were healthy by the time exfoliation occurred.

Does low-cost GIC have the same survival rate as high-viscosity GIC in atraumatic restorative treatments? A RCT.

Atraumatic Restorative Treatment (ART) is one of the strategies used to control dental caries; it involves hand instruments for removal of carious tissue, and restorations using high-viscosity Glass Ionomer Cement (GIC). The present controlled clinical trial aimed to evaluate the performance of low-cost GIC indicated for ART in primary teeth, compared with high-viscosity GIC, after one year of follow-up. Two-to six-year-old children with dentin caries lesions on one or two surfaces of anterior and posterior teeth were selected. The children were randomly assigned to 2 groups according to the restorative material used: G1 (control) - Ketac Molar®; G2 (experimental) - Vitro Molar®. Treatments were performed in a school setting, following the guidelines of the ART. A total of 728 restorations were performed in 243 children. Descriptive analysis and Poisson regression were applied, with a significance level of p < 0.05. After 12 months, 559 (76.8%) restorations were re-evaluated. The success rate was evaluated by the prevalence ratio (PR), associated with restorations performed in primary second molars (PR = 1.21; 95%CI = 1.03-1.42), and with small (PR = 1.35; 95%CI = 1.14-1.60) or medium cavities (PR = 1.29; 95%CI = 1.08-1.55), using Ketac Molar® material (PR= 1.07; 95%CI = 1.01-1.15), considering p < 0.05. Small or medium restorations in primary second molars performed with high-viscosity GIC (Ketac Molar®) were more successful than restorations performed with low-cost GIC indicated for ART.

Consumption of Acidic Beverages is a Predisposing Factor for Erosive Tooth Wear in Preschool Children: A Population-based Study.

Purpose: In a cross-sectional population-based study of 888 5-year-old preschoolers from Teresina, Brazil, to determine the prevalence and factors associated with erosive tooth wear (ETW).
Materials and Methods: In a questionnaire, parents provided information on sociodemographic factors, their children's eating/drinking habits, and oral health. Dental examination was performed at the schools by two calibrated examiners for the diagnosis of ETW, following the criteria of the modified O'Brien Index.
Results: The prevalence of ETW was 3.3%. The maxillary incisors were the most highly affected teeth, followed by the mandibular and maxillary molars. The majority of the lesions reached only the enamel (72.1%) and up to 1/3 of the dental surface (63.1%). The occlusal surface was the most affected (47.8%). Preschoolers who had an acidic food-consumption profile had a 2.74 times (95% CI = 1.03-7.30) higher chance of having ETW than children without this profile.
Conclusion: The prevalence of erosive tooth wear on the deciduous teeth was low and associated with the consumption of acidic beverages.

Prevalência e severidade da cárie dentária em escolares do Ensino Fundamental de um município vulnerável / Prevalence and severity of dental caries in elementary school students in a vulnerable municipality

Resumo Introdução A cárie dentária ainda é um problema de saúde pública na maioria dos países industrializados, com maior prevalência nas populações mais vulneráveis socioeconomicamente. Objetivo Avaliar a prevalência e a severidade da cárie dentária, e as ações curativas realizadas em escolares de 6 a 14 anos do Ensino Fundamental durante quatro meses de intervenção. Material e método Estudo transversal foi realizado com 130 escolares do município de Sarandi-PR. Para o diagnóstico da cárie dentária, foram utilizados os índices ceo-d, CPO-D e ICDAS II. Os escolares receberam atendimento curativo de acordo com as necessidades apresentadas, associado a atividades educativas preventivas. Resultado A prevalência de cárie dentária foi de 70% e 83%, segundo os índice ceo-d/CPO-D e ICDAS II, respectivamente. Os códigos referentes ao ICDAS II com maior prevalência foram ICDAS 5 e 6 (1,57% e 3,69%, respectivamente), enquanto o código 4 foi o de menor prevalência (0,30%). A maioria dos tratamentos restauradores foi realizada pela técnica de Tratamento Restaurador Atraumático (ART) (150 restaurações). Foram realizadas 90 aplicações de verniz fluoretado em lesões iniciais de cárie. Os tratamentos de maior complexidade foram encaminhados para a Unidade Básica de Saúde do município. Dos 32 escolares referenciados, 21 compareceram e nestes foram realizados tratamentos endodônticos e exodontias de dentes decíduos e permanentes. Conclusão A população estudada apresenta prevalência alta de cárie e, após quatro meses de intervenção, observou-se que o ART foi resolutivo para a maioria das necessidades de tratamento (59,2%), apresentando-se como uma estratégia eficiente que pode ser implementada em locais que não oferecem a estrutura de um consultório odontológico.

Abstract Introduction Dental caries is still a public health problem in most industrialized countries, with a higher prevalence in the most socioeconomically vulnerable populations. Objective The aim of this study was to evaluate the prevalence and severity of dental caries and curative actions performed in students from 6 to 14 years of elementary school during four months of intervention. Material and method Cross-sectional study was conducted with 130 students from Sarandi / PR. To diagnose dental caries, dmft, DMFT and ICDAS II indices were used. The students received curative care according to the needs presented associated with preventive educational activities. Result The prevalence of dental caries was 70% and 83% according to the ceo-d / CPO-D and ICDAS II index, respectively. The codes for ICDAS II with thw highest prevalence were ICDAS 5 and 6 (1.57% and 3.69% respectively), while Code 4 was the least prevalent (0.30%).Most restorative treatments were performed by the ART technique (150 restorations). Ninety applications of fluoride varnish were performed on initial carious lesions. The most complex treatments were referred to the Basic Health Unit of the municipality. Of the 32 students referred, 21 attended and endodontic treatments and primary and permanent teeth extraction were performed. Conclusion The studied population has a high prevalence of caries and after four months of intervention, it was observed that ART was decisive for most treatment needs (59.2%), presenting itself as an efficient strategy that can be implemented in places that do not offer the structure of a dental office.

A descolagem de bráquetes ortodônticos são frequentes na prática clínica. O conhecimento dos fatores associados à descolagem é relevante para maior efetividade clínica na movimentação dentária. Este estudo teve por objetivo avaliar a ocorrência de descolagem de bráquetes e fatores associados em pacientes que concluíram tratamento ortodôntico. Foram avaliados os prontuários de 205 pacientes de uma clínica privada tratados ortodonticamente por um único operador entre 2000 e 2013, nos quais foram utilizados o mesmo tipo de bráquete e sistema adesivo para a colagem. Para a análise univariada foram utilizadas tabelas de frequências e médias de tendência central e dispersão. Na análise bivariada foram utilizadas tabelas de dupla entrada e teste Qui-quadrado ou Exato de Fisher. Em 45,9% dos pacientes não ocorreu descolagem de bráquetes durante todo o tratamento ortodôntico. Dos 54,1% pacientes que descolaram bráquetes, 46,3% descolaram de um a cinco bráquetes. Houve associação entre a descolagem e o tempo de tratamento. O dente que apresentou maior frequência de descolagem de bráquete foi o pré-molar inferior (44,7%). Descolagens ocorreram em 54,1% dos pacientes ao longo de todo o tratamento ortodôntico e houve associação entre descolagem e tempo de tratamento. (AU)

Introduction: Orthodontic brackets debonding is common in clinical practice. The knowledge of the factors associated to bracket debonding is relevant for greater clinical effectiveness in tooth movement. Objective: This study aimed to evaluate the occurrence of brackets debonding and associated factors in patients who completed orthodontic treatment. Material and Methods: The records of 205 orthodontic patients from a private clinic treated by a single operator between 2000 and 2013 were analysed, the same type of bracket and adhesive system were used for the bonding. For univariate analysis, tables of frequency and average of central tendency and dispersion were used. In the bivariate analysis were used double-entry tables and Chi-square test or Fisher's exact test. Results: There was no bonding failure of brackets in 45.9% of the patients during the entire orthodontic treatment. Of the 54.1% patients with bonding failure, 46.3% occurred in one to five brackets. There was an association between debonding and treatment time. The tooth with the highest bracket debonding frequency was the lower premolar (44.7%). Conclusions: Orthodontic brackets bonding failure occurred in 54.1% of patients throughout the orthodontic treatment and was associated with treatment time. (AU)

Impact of Developmental enamel defects on quality of life in 5-year-old children.

BACKGROUND: Developmental enamel defects (DDE) represent one of the prevalent oral problems in childhood; however, few studies have evaluated its impact on quality of life in the children's own perception. AIM: To evaluate the DDE impact on quality of life of 5-year-old children. METHODS: This cross-sectional observational study assessed 566 children aged 5 years old, in Teresina, Piauí, Brazil, according to their self-perceptions. Children answered the Pediatric Quality of Life Inventory™ Version 4.0 and Oral Health Scale. The dmft index, modified DDE index and Foster and Hamilton criteria were used to diagnose dental caries, DDE and malocclusion, respectively. A single examiner performed the clinical examination. Descriptive analyses and Poisson regression with robust variance were performed. RESULTS: The prevalence of DDE was 33.7%. For children's self-reports, the presence of DDE had a negative association with oral health-related quality of life (OHRQoL; PR 1.09, 95% CI 1.02-1.15). Enamel hypoplasia had a negative impact on the physical function (PR 1.05; 95% CI 1.01-1.10) and oral health (PR 1.06, 95% CI 1.01-1.11) domains. Diffuse opacity had a negative impact on the social aspect (PR 1.09, 95% CI 1.02-1.18). CONCLUSIONS: Enamel defects had a negative impact on OHRQoL according to the self-reports of the children.

Does low-cost GIC have the same survival rate as high-viscosity GIC in atraumatic restorative treatments? A RCT

Abstract Atraumatic Restorative Treatment (ART) is one of the strategies used to control dental caries; it involves hand instruments for removal of carious tissue, and restorations using high-viscosity Glass Ionomer Cement (GIC). The present controlled clinical trial aimed to evaluate the performance of low-cost GIC indicated for ART in primary teeth, compared with high-viscosity GIC, after one year of follow-up. Two-to six-year-old children with dentin caries lesions on one or two surfaces of anterior and posterior teeth were selected. The children were randomly assigned to 2 groups according to the restorative material used: G1 (control) - Ketac Molar®; G2 (experimental) - Vitro Molar®. Treatments were performed in a school setting, following the guidelines of the ART. A total of 728 restorations were performed in 243 children. Descriptive analysis and Poisson regression were applied, with a significance level of p < 0.05. After 12 months, 559 (76.8%) restorations were re-evaluated. The success rate was evaluated by the prevalence ratio (PR), associated with restorations performed in primary second molars (PR = 1.21; 95%CI = 1.03-1.42), and with small (PR = 1.35; 95%CI = 1.14-1.60) or medium cavities (PR = 1.29; 95%CI = 1.08-1.55), using Ketac Molar® material (PR= 1.07; 95%CI = 1.01-1.15), considering p < 0.05. Small or medium restorations in primary second molars performed with high-viscosity GIC (Ketac Molar®) were more successful than restorations performed with low-cost GIC indicated for ART.

Profile of Brazilian Dental Undergraduates who participated of Science Without Borders Program and their perceptions on sandwich course / Perfil dos estudantes de Odontologia brasileiros que participaram do Programa Ciência sem Fronteiras e suas percepções sobre a graduação

The Science without Borders (SwB) program was created in 2011 aiming to internationalizing education in Brazil and providing highly qualified training abroad. However, in 2015, it ended the offer of scholarships for undergraduates, which allowed several opportunities. The objective of this study was to evaluate the profile of Dental undergraduate students who participated in the SwB program and their perceptions about this experience. This is an evaluative research developed with students who participated in SwB in the sandwich modality, in which the student continues being enrolled in his university of origin, while studying for period in another institution abroad. Semi structured questionnaire was developed using the GoogleDocs® digital platform, addressing the sociodemographic and academic profile of participants and aspects related to the organization and operation of the program. From 745 former SwB Dental students, 109 (14.6%) answered the questionnaire. Most of them were female (65.1%), from public institutions (89%), located in the Northeast (34.9%) and Southeast (26.6%), with proficiency in English (82.6%), and intention to become a researcher (51.4%). The fellows indicated that the program's objectives were partially fulfilled (59.63%). They considered themselves more qualified, professionally, due to the sandwich course offered by SwB. However, they pointed out several limitations: lack of organization of development institutions, use of disciplines and control and inspection mechanisms. It was possible to outline the profile of program participants, as well as to characterize the functioning of SwB for Dental students, according to their perceptions (AU).

O programa Ciência sem Fronteiras (CsF) foi criado em 2011 com o objetivo de internacionalizar a educação no Brasil e prover treinamento altamente qualificado no exterior. Entretanto, em 2015, encerrou a oferta de bolsas de estudo para alunos de graduação, que permitiam diversas oportunidades. O objetivo deste estudo foi avaliar o perfil de graduandos de Odontologia que participaram do programa CsF e suas percepções sobre essa experiência. Tratase de uma pesquisa avaliativa desenvolvida com estudantes que participaram do CsF na modalidade sanduíche, em que o estudante continua matriculado em sua universidade de origem enquanto estuda por período em outra instituição no exterior. Um questionário semiestruturado foi desenvolvido utilizando a plataforma digital GoogleDocs®, abordando o perfil sociodemográfico e acadêmico dos participantes e aspectos relacionados à organização e ao funcionamento do programa. Dos 745 estudantes de Odontologia participantes do CsF, 109 (14,6%) responderam ao questionário. A maioria era do sexo feminino (65,1%), oriundos de instituições públicas (89%), localizadas no Nordeste (34,9%) e Sudeste (26,6%), com proficiência em inglês (82,6%) e intenção de se tornar pesquisador (51,4%). Os bolsistas indicaram que os objetivos do programa foram parcialmente cumpridos (59,63%). Consideraram-se mais qualificados, profissionalmente, devido à graduação sanduíche oferecida pelo CsF. No entanto, apontaram várias limitações: a falta de organização das instituições de fomento, de aproveitamento de disciplinas e de mecanismos de controle e inspeção. Foi possível traçar o perfil dos participantes do programa, bem como caracterizar o funcionamento do CsF para os estudantes de Odontologia, de acordo com suas percepções (AU).

Cellular profile of primary molars with pulp necrosis after treatment with antibiotic paste.

The interradicular region of primary molars is permeated by many foramina, channels and accessories that connect the pulp cavity with the periapical tissues anatomically. Thus, pulp decomposition products or drugs used in endodontic treatment can trigger inflammatory reactions. The aim of this study was to evaluate the blood cell profile of the alveolar region after extraction of primary molars treated with CTZ paste. Forty-eight primary molars were selected with clinical and radiographic signs of extraction. The sample was divided into three groups with 16 teeth each: Group 1-healthy teeth; Group 2-untreated decayed teeth; and Group 3-teeth treated with CTZ paste. Immediately after the extraction, blood from the interface of the tooth socket was collected and smears were performed for further evaluation. The slides were stained by the Fast Panoptic® method and analysed by two previously trained examiners who counted the leucocytes in sets of 100 cells/slide, differentiating them into neutrophils, lymphocytes, monocytes, eosinophils and basophils. The data were analysed statistically by the MANOVA test. The blood samples from Group 2 differed significantly from Group 1 samples for all classes of leucocytes, except basophils, with higher average for lymphocytes (62.56), monocytes (7.81) and eosinophils (2.31). For Group 3, there was a relative difference (P < 0.05) to Group 2, of monocytes and eosinophils values. The blood cellularity interface in the tooth socket of primary teeth treated with CTZ paste is similar to those of healthy, exfoliated teeth and physiologically different from untreated decayed teeth.
