Oral Health and Behavioral Management of Children with Autistic Spectrum Disorder: A 30-year Retrospective Study.

PURPOSE: This article aims to determine the oral health status, the dental treatment, the behavioral management techniques, and the follow-up of pediatric autistic spectrum disorder (ASD) patients treated at the Clinic for Pediatric Patients with Disabilities (CPPD) at a public university in Brazil. METHODS: The medical records of all the patients seen between 1990 and 2020 were evaluated. Data were collected on the autistic patients' medical and dental conditions, treatments, behavior during dental visits, behavioral management techniques used, and the entire follow-up period at the clinic. The Student's t-test and chi-square tests were used to perform the statistical analysis (α = 0.05%). RESULTS: Sixty-six records of ASD children were analyzed from a total of 656 dental records. The majority were male (80.3%). The mean age was 7.39 ± 2.75 years. All the children had a cognitive deficit, and 62.5% used medication. Most of the children arrived with caries lesions (56.1%), and the mean number of decayed, missed and filled teeth in both the deciduous (dmft-d) and permanent dentition (DMFT) was 2.45 ± 3.13 and 0.87 ± 1.51, respectively. The restorative technique was the most commonly used procedure (54.5%), and protective stabilization was the most frequently used behavioral management technique (18.2%). Of the children who sought treatment, 86.4% were discharged, and 15.2% abandoned the procedure. The majority (those discharged) continued to undergo regular follow-up at the clinic (86%), and the incidence of new caries lesions observed was 33.33% Conclusions: Although our ASD patients had a high frequency of caries and dental treatment needs, we observed good adherence to the treatment, with a low dropout rate, and high discharge rate.

Relationship between depression, alcohol and / or tobacco abuse of those responsible and children's oral health

Objective :To investigate the influence of parental depression and smoking and alcohol use by parents/caregivers use on oral health in children aged 5-11 years of both sexes. Methods: A cross-sectional study was conducted involving 85 children and their parents/caregivers. Adult respondents completed three questionnaires to assess depression and alcohol and tobacco use: two versions of the PHQ (PatientHealth Questionnaire; PHQ-2 and PHQ-9), AUDIT (Alcohol Use DisordersIdentification Test) for risk assessment of alcohol dependence and abuse, and the Fagerström Test for Nicotine Dependence (FTND). The PHQ-2 contained two questions requiring an affirmative or negative answer. Children underwent oral examinations to evaluate biofilm control, gingival bleeding and caries index, specifically DMFT index. Relationships among variables were evaluated using chi-squared tests and Fisher's exact test. Results: Only 10.6% of parents and caregivers consumed tobacco and 24,7% of parents or caregivers manifested depressive symptoms. Regarding alcohol consumption, 10.6% of caregivers presented risk consumption or dependence. A positive association was found between children'sgingival bleeding and their caregivers' risk of alcohol dependence (p=0.038). Conclusion: A positive association between caregivers' risk of alcohol dependence and the presence of gingival bleeding in children was found. Caregivers' depression and alcohol and tobacco use did not influence children's caries.

Objetivo: Investigar a influência da depressão parental e do uso de cigarro e álcool pelos pelos pais/cuidadores na saúde bucal de crianças de 5 a 11 anos de ambos os sexos. Métodos: Um estudo do tipo transversal foi conduzido com 85 crianças e seus respectivos cuidadores. Para detectar a presença de depressão, duas versões do PHQ (Pacient Health Questionnaire) foram aplicadas: o PHQ-2, contendo duas perguntas com opção de resposta afirmativa ou negativa e o segundo, PHQ-9. Para o uso de álcool foi aplicado o AUDIT (Alcohol Use Disorders Identification Test) para avaliação do risco de dependência e abuso de álcool; e o Fagerstrom para dependência de nicotina. As crianças foram submetidas a exames orais para avaliação do controle de biofilme, sangramento gengival e presença de cárie (índices CPO-D e ceo-d). Para verificar a associação entre as diferentes variáveis, foram utilizados os testes Qui-quadrado e Exato de Fisher. Resultados: Somente 10,6% dos responsáveis faziam uso de tabaco e 24,7% dos mesmos apresentavam sintomas de depressão. Em relação ao consumo de álcool, 10,6% apresentavam consumo de risco ou dependência. Verificou-se associação entre sangramento gengival nas crianças e o risco de dependência de álcool dos responsáveis (p=0,038). Conclusão: Concluiu-se que há uma associação positiva entre o risco de dependência de álcool dos responsáveis e a presença de sangramento gengival no paciente e que a depressão, o uso de álcool e de tabaco pelos cuidadores não influência na experiência de cárie das crianças.

Types of Feeding and Presence of Harmful Oral Habits in Children with Cleft Lip and/or Palate: A Pilot Study

Abstract Objective: To verify the relationship between the types of feeding and presence of harmful oral habits (HOH) in children with cleft lip (CL), palate (CP) and cleft lip and palate (CLP), as well as to compare the different types of cleft to each other. Material and Methods: A form was applied to the parents of 162 children (3-5 years old), addressing the following variables: gender, cleft type, age, socioeconomic conditions, type of breastfeeding, presence of HOH, and the parents' knowledge about the consequences of oral habits. The data obtained were analyzed by chi-square test (p<0.05). Results: The majority of children (83.3%) were bottle-fed and 12.3% were exclusively maternal breastfed. The main reason for weaning was the presence of cleft (59.9%). Breastfeeding was significantly higher in children with CL (75%) in comparison with CP (20%) and CLP (5%) (p<0.001). Children with CLP were 12 times more likely to be bottle-fed than children with CL (OR=12.21; CI=4.09-36.45). The prevalence of HOH was 37%. Sociodemographic characteristics were not associated with the presence of HOH (p>0.05). The type of feeding and cleft were not decisive to present some type of HOH (p>0.05) and 87% of parents stated that HOH could lead to serious complications of tooth misalignment. Conclusion: The type of feeding and fissure did not determine the acquisition of harmful oral habits in children with cleft. However, the greater the fissure's complexity, the lesser the chance of children receiving exclusive breastfeeding.

A successful dental management in a child with Cornelia de Lange Syndrome: rare case of Cornelia de Lange Syndrome in child / O sucesso do manejo odontológico em criança com Síndrome Cornelia de Lange: um caso raro da Síndrome Cornelia de Lange em criança

Background: the Cornelia de Lange Syndrome (CDLs) is a rare and complex syndrome characterized, basically, by psychomotor retardation associated with a number of congenital malformations. Aims: this paper reports the case of an 11-year-old female child diagnosed with Cornelia de Lange Syndrome (CdLS) and her successful dental management. Case report: the patient had severe mental retardation, definite negative behavior and the clinical findings included oral and physical changes. The patient's oral hygiene was deficient with the presence of calculus and gingivitis, besides several active caries lesions in permanent and deciduous dental elements. The treatment consisted in guidance for caregivers about oral hygiene and diet, and the dental procedures were performed under general anesthesia. Currently, the patient is accompanied by monthly follow-ups. Conclusions: the lack of knowledge about oral hygiene and cariogenic diets was identified as a one of the reasons for the oral diseases present. Due to the need to care for the other more serious and complex health problems, the oral diseases had evolved faster than usual and thus were difficult to treat and maintain thereafter. Under such conditions, the dentist plays a key role within a multidisciplinary team. From the guidance and knowledge provided in the dental clinic, there was a significant improvement in the life quality of the child and her family

Aprendizagem Baseada em Problemas como ferramenta para o ensino da Odontopediatria em nível de especialização / Problem Based Learning as a teaching tool in Pediatric Dentistry specialization

O tema abordado neste estudo é o processo educacional na formação do cirurgião-dentista nos tempos atuais. O objetivo do trabalho foi implementar a Aprendizagem Baseada em Problemas (PBL - Problem Based Learning) como ferramenta de ensino no curso de especialização em Odontopediatria da Universidade Federal do Rio de Janeiro. A metodologia dividiu-se em duas etapas: a primeira, da elaboração e aplicação do método de ensino, que ocorreu durante o primeiro semestre de 2016, com a carga horária de duas horas semanais, na disciplina Temas em Odontopediatria. A segunda etapa correspondeu à avaliação da ferramenta pelos estudantes, para determinar a percepção dos mesmos quanto ao desenvolvimento do PBL como ferramenta de ensino na formação em Odontopediatria. O tratamento dos dados foi feito a partir da análise de conteúdo, numa abordagem metodológica qualitativa. Entre os resultados obtidos estão o desenvolvimento do pensamento crítico, maior autonomia, liberdade para questionar e maior participação discente. O reforço do vínculo entre os estudantes também se expressou promovendo uma rede de apoio e dando suporte ao protagonismo, tornando-os sujeitos ativos na construção do seu processo de aprendizagem (AU).

The subject of the present study was the current educational process for training dentists. The subject emerged from the need to reorient the teaching process in the Dental Pediatrics Specialization Course of the Federal University of Rio de Janeiro (UFRJ). The study aimed to implement problembased learning as a teaching tool in the Dental Pediatrics Specialization Course of UFRJ. The method was divided into two steps: initially the development and application of the method during the first semester of 2016, with a two-hour a week work load in the Topics on Dental Pediatrics discipline. The second step, the assessment of the tool, used a questionnaire answered by students of the discipline to determine their perception regarding the development of the problem-based learning method as a teaching tool in Dental Pediatrics training. Data were submitted to content analysis, using a qualitative methodological approach. Among results obtained were development of analytical thinking, greater autonomy, freedom to question, and more participation of students. Relations among students were also strengthened, promoting a support network and sustaining the empowerment of students, turning them into active participants in the construction of their learning process (AU).

Demineralizing potential of dental biofilm added with Candida albicans and Candida parapsilosis isolated from preschool children with and without caries.

This study aimed to investigate the demineralizing potential of dental biofilm added of Candida albicans (CA) and Candida parapsilosis (CP), isolated from preschoolers with and without caries. Bovine enamel blocks (n = 48), with initial hardness = 341.50 ± 21,83 kg/mm2 were fixed in 24 well plates containing culture media. A pool of children saliva (PHS) was the inoculum for biofilm formation in the presence or absence of isolated CA or CP in accordance with each group (G n = 8): G1 - PHS; G2 - PHS + CA isolated from children with caries; G3 - PHS + CP isolated from children with caries; G4 - PHS + CA isolated from children without caries; G5 - PHS + CP isolated from children without caries; and G6 - blank control. The plates were incubated at 37 °C for 5 days, with daily changes of culture media. The microhardness loss percentage (MHL%) of the blocks was calculated, taking in account the hardness values before and after the experiment. Dental biofilm became more cariogenic, independently of the isolated Candida species. The highest MHL% was observed in G4 (85.90 ± 8.72%) and G5 (86.13 ± 6.74%) compared to the others (p < 0.001): G1 (34.30 ± 14,30%) < G2 (59.40 ± 10.56%) and G3 (65.80 ± 6.36%) < G6 (13.68 ± 4.86%) (p < 0.001). C. albicans and C. parapsilosis isolates induced the demineralization of the dental enamel.

Effect of highly active antiretroviral therapy use on oral manifestations in pediatric patients infected with HIV.

AIMS: The aim was to assess the prevalence of oral lesions in HIV-infected children undergoing highly active anti-retroviral therapy (HAART), and the association between the duration of HAART usage and oral lesions. SUBJECTS AND METHODS: Totally, 111 medical and dental records of HIV-infected children, aged from 2 to 16 years old were reviewed for medical data, presence of oral lesions, and caries prevalence. According to the type of medication, the children were grouped as follows: 51 were under HAART (G1), 46 were using anti-retroviral medication (G2), and 14 were using no medication (G3). RESULTS: The majority of the HIV children had AIDS (65.8%), of which 86.3% were in G1, 63% in G2, and 0% in G3. The mean length of therapy was 34.4 months, with no difference between groups (Kruskal-Wallis; P = 0.917). The prevalence of the oral lesions was 23.4%, namely, G1 was 27.5%, G2 was 21.7%, and G3 was 14.3% (P > 0.05). Gingivitis was the most common oral manifestation (15.3%) seen in the three groups, followed by gingival linear erythema and pseudomembranous candidiasis in G1 and G2. The mean values regarding deft and DMFT indexes were, respectively, 3.2 and 1.9 (G1), 2.8 and 1.6 (G2), and 3.8 and 3.0 (G3). For the patients without AIDS (n = 38), oral manifestations were seen in 29.4% of G2 compared to G1, with 0% (Chi-square; P > 0.05). In terms of therapy duration, 47.65% of the patients who had been under HAART for 18 months or less had oral manifestations, compared to 13.3% of those who had been treated for a longer time (Chi-square; P = 0.007). CONCLUSIONS: Although the prevalence of oral lesions was similar between the groups, it was less in patients without AIDS and those under HAART. The duration of HAART usage had a significant influence on the prevalence of these lesions.

Salivary lactoferrin in HIV-infected children: correlation with Candida albicans carriage, oral manifestations, HIV infection and its antifungal activity.

OBJECTIVES: This study aimed to evaluate the concentration of lactoferrin in the saliva of HIV infected and healthy children and analyze the associations between lactoferrin levels, Candida sp. colonization, oral manifestations and medical data. Also, the antifungal ability of lactoferrin to inhibit the growth of Candida albicans isolated from saliva of these children was investigated in vitro. SUBJECTS AND METHODS: Saliva was collected from 70 HIV-infected and 50 healthy children, followed by oral manifestation assessments. The salivary lactoferrin was quantified using an ELISA Kit. The salivary samples were cultured and the Candida spp. colonies counted and then identified by sugar assimilation and fermentation. The antifungal activity of lactoferrin was analyzed in vitro with 10 isolates of C. albicans from each group. RESULTS: The HIV infected children (mean age 9.8 ± 2.8) had higher lactoferrin levels (median 6.13 µg/ml (3.58-7.89)) and were colonized three times more by Candida sp. than the control group (mean age 9.4 ± 2.4) (median 5.74 µg/ml (3.12-6.86)) (p=0.003). Statistical associations were found considering the salivary lactoferrin levels and Candida sp. and oral manifestations between the groups. No associations between lactoferrin concentrations and oral manifestations, immunosuppression, presence of AIDS and use of HAART were observed in the HIV group. The percentage of dead C. albicans due to lactoferrin was inversely proportional to C. albicans cell density for both groups (p<0.001). CONCLUSIONS: HIV-infected children have higher concentrations of lactoferrin and it was associated with Candida sp. colonization but no association with medical data was found. Also, both groups showed similar lactoferrin antifungal activity.

Current status of herpesvirus identification in the oral cavity of HIV-infected children.

INTRODUCTION: Some viruses of the Herpesviridae family are frequently the etiologic agents of oral lesions associated with HIV. The aim of this study was to identify the presence of herpes simplex virus types 1 and 2 (HSV-1, HSV-2), Varicella Zoster virus (VZV), Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), human herpesvirus type 6, type 7 and type 8 (HHV-6, HHV-7 and HHV-8) in the oral cavity of HIV-infected children/adolescents and verify the association between viral subtypes and clinical factors. METHODS: The cells of oral mucosa were collected from 50 HIV infected children/adolescents, 3-13 years old (mean age 8.66). The majority (66%) of selected were girls, and they were all outpatients at the pediatric AIDS clinic of a public hospital in Rio de Janeiro. Nested-PCR was used to identify the viral types. RESULTS: Absence of immunosuppression was observed in 66% of the children. Highly active antiretroviral therapy (HAART) was used by 72.1% of selected and moderate viral load was observed in 56% of the children/adolescents. Viral types were found in 86% of the children and the subtypes were: HSV-1 (4%), HSV-2 (2%), VZV (4%), EBV (0%), HCMV (24%), HHV6 (18%), HHV-7 (68%), HHV8 (0%). CONCLUSIONS: The use of HAART has helped to reduce oral lesions, especially with herpes virus infections. The health professionals who work with these patients should be aware of such lesions because of their predictive value and the herpes virus can be found circulating in the oral cavity without causing lesions.

Salivary proteins as a biomarker for dental caries--a systematic review.

AIM: To develop a systematic review based on the relation between salivary proteins and dental caries by comparing subjects with and without caries experience and to evaluate whether salivary proteins can be considered biomarkers for dental caries or not. METHODS: An electronic search was performed in the PubMed Medline, Ovid Medline, ISI Web of Science, Medline, Cochrane Library, Lilacs, Scielo, BBO, Paho and Wholis databases applying the following MeSH terms: "dental caries" OR "tooth demineralization" OR "dental caries susceptibility" OR "dental enamel solubility" AND "salivary proteins and peptides" OR "saliva" AND "proteins". To be eligible for the systematic review, the observational controlled studies had to have groups with and without caries experience. Studies with high risk of bias were excluded. RESULTS: From a total of 188 identified studies, only seven were included in this systematic review. Four studies were classified as "low risk of bias" and three as "moderate risk of bias". Three studies reported a relation between salivary proteins and dental caries. CONCLUSION: There was not sufficient evidence to establish salivary proteins as a biomarker for this disease although three of the seven studies showed a relation between salivary proteins and dental caries in terms of protein phenotypes, total protein concentration and protein molecular weight.

Dental needs and management of children with special health care needs according to type of disability.

PURPOSE: The purpose of this study was to investigate the dental needs and management of special health care needs children in Rio de Janeiro, Brazil, according to the type of disability. METHODS: Records of 428 0- to 19-year-old patients who received dental treatment at the Patients Special Care Needs Clinic (Department of Pediatric Dentistry and Orthodontics, School of Dentistry, Universidade Federal do Rio de Janeiro) from 1996-2009 were analyzed. Information about the type of disability, use of medication, dental exam findings, management during treatment, dental treatment performed, and follow-up examinations were collected. Children were divided into 2 groups: those with medical conditions and those with intellectual disability. RESULTS: Patients with medical conditions used more medications and were older than those with intellectual disability. The most common dental treatments received were dental restorations (63%) and extractions (47%). There was no association between the type of disability and dental treatment needed. Children with intellectual disability were 3 times more likely to need general anesthesia and 7 times more likely to need physical restraint for dental care than the other group. CONCLUSIONS: Children with intellectual disability have a greater chance of requiring advanced management techniques during dental treatment. The development of effective oral health programs is recommended as well as a specific education program for their parents.

Atividade antifúngica da clorexidina em biofilmes de Candida spp / Antifungal activity of chlorhexidine on Candida spp. biofilm

Candidíase oral é a infecção oportunista mais comum em pacientes imunocomprometidos, sendo a clorexidina um importante antimicrobiano auxiliar no seu tratamento. O objetivo do presente estudo foi avaliar o efeito antifúngico de diferentes soluções de clorexidina (Periogard®, NoPlak Max®, Noplak®, Perioxidin®, Clorexidina 0.06%, Paradontax® e Clorexidina 1%) sobre biofilmes artificiais de Candida spp.: C. albicans (ATCC36801); C. parapsilosis (ATCC22019); C. krusei (ATCC6258); C. glabrata (ATCC2001) e C. tropicalis (ATCC750). As cepas foram cultivadas em meio de cultura BHI ágar sobre fragmentos de esmalte bovino por 72 horas a 37 °C. Após o crescimento, cada fragmento de esmalte bovino foi imerso nas diferentes soluções de Clorexidina por 3 minutos. Nistatina e solução salina foram utilizadas como controle negativo e positivo, respectivamente. Para remoção das células não aderidas, os fragmentos foram então imersos em solução salina por 10 minutos e agitados em vortex. Alíquotas de 100 µL foram inoculadas em placas contendo BHI ágar por 24 horas a 37 °C para contagem de unidades formadoras de colônias (UFC). Observamos que o número de UFC de C. albicans e C. parapsilosis, apresentou um percentual de redução variando de 79 a 99% quando do uso das diferentes soluções (p < 0,001), o mesmo não foi observado para o NoPlak Max® (2,94 e 1,3%, respectivamente); Para C. krusei e C. glabrata, a solução menos efetiva foi a Nistatina (23 e 3,4%, respectivamente) enquanto que para C. tropicalis, todas as soluções apresentaram um alto percentual de redução (99 a 100%). As soluções de clorexidina foram capazes de reduzir significativamente o número de UFC provenientes de biofilme de Candida spp. in vitro.

Oral candidiasis is the most common opportunistic infection in immunocompromised patients and chlorhexidine is an important antimicrobial for its treatment. The antifungal effect of different CHX solutions (Periogard®, NoPlak Max®, Noplak®, Perioxidin®, Chlorhexidine 0.06%, Paradontax® and Chlorhexidine 1%) was evaluated on artificial biofilms of Candida spps: C. albicans (ATCC36801), C. parapsilosis (ATCC22019), C. krusei (ATCC6258), C. glabrata (ATCC2001) and Candida tropicalis (ATCC750). The strains were grown, in a BHI agar medium on bovine teeth enamel for 72 hours at 37 °C. After growth, the fragments were immersed in the CHX solutions for 3 minutes. Nystatin and saline solutions were used as positive and negative controls respectively. To remove the non-adhered cells, the fragments were inoculated in saline solution for 10 minutes, transferred to Falcon tubes containing saline solution and mixed in a vortex. Aliquots of 100 µL were inoculated on BHI agar for 24 hours at 37 °C to count the number of colony forming units (CFU). We observed that the number of (CFU) of C. albicans and C. parapsilosis, showed a reduction rate ranging from 79 to 99% with the use of different solutions (p < 0.001), except for NoPlak Max® (2.94 and 1.3%, respectively). For C. krusei and C. glabrata, nystatin was the least effective solution (23 and 3.4%, respectively); and for C. tropicalis, all the substances presented a high reduction percentage (99-100%). The chlorhexidine solutions were able to reduce the colony forming units of Candida biofilm.

Levels of salivary IgA antibodies to Candida spp. in HIV-infected adult patients: a systematic review.

OBJECTIVE: To perform a systematic review of published data with the aim of evaluating the levels of IgA antibodies to Candida albicans in HIV-infected adult patients. METHODS: The search strategy was based on PubMed, Web of Science, Google Scholar, Cochrane and EMBASE databases. Also, the reference lists of included studies were searched. All abstracts found by electronic searches were independently scrutinized by two reviewers. To be eligible for review, the controlled studies had to present the following characteristics: samples of both HIV-infected adults and noninfected adults; appropriate HIV-diagnostic tests for both patient groups (case and control); IgA-diagnostic test applied to a similar population sample. RESULTS: Of 144 studies found, only six met the initial eligibility criteria, but three were excluded after a thorough analysis. To assess the methodological quality of the three remaining studies, they were categorized according the risk of bias. The three selected studies revealed that the levels of C. albicans-specific IgA antibody were higher in HIV-infected individuals compared with the control group. CONCLUSION: Adequate IgA antibody responses to C. albicans appear to be maintained, since the levels of these antibodies were higher in all studies selected. Although the findings of this systematic review are encouraging, the scientific evidence should be interpreted carefully because there are only a few reports in the literature, mostly because of the lack of important methodological details or the varying methodologies employed.

O impacto das imunoglobulinas salivares sobre Candida spp em pacientes pediátricos infectados pelo HIV / The impact of salivary immunoglobulins on Candida spp in HIV infected paediatric patients

Pacientes pediátricos imunodeprimidos, ou seja, aqueles que não têm a capacidade de responder adequadamente a um estímulo antigênico, estão mais sujeitos a desenvolver infecções oportunistas, tais como as infecções fúngicas. Dentre elas, pode-se citar a candidíase bucal, causada pelas Candida spp, comumente encontrada em crianças infectadas pelo HIV. Este trabalho teve como objetivo realizar uma revisão da literatura sobre a relação entre imunoglobulinas salivares, que constituem o principal agente na linha de defesa da mucosa bucal, com as Candida spp em pacientes pediátricos infectados pelo HIV, ressaltando a importância desses anticorpos.

Pediatric HIV-related oral manifestations: a five-year retrospective study

O objetivo deste estudo foi realizar um acompanhamento descritivo retrospectivo da freqüência de manifestações bucais, da condição sistêmica e do tipo de medicação utilizada em um grupo de crianças e adolescentes infectados pelo HIV após a introdução da terapia anti-retroviral combinada. Cinqüenta e oito pacientes foram examinados em 2001/2002, enquanto seus exames médicos e odontológicos retrospectivos (1997 a 2000) foram pesquisados em prontuário. Foram observados 7 novos casos de AIDS em uma amostra de 19 pacientes, enquanto 46,5% da amostra total (n = 58) progrediram quanto à classificação da infecção pelo HIV. Não foram observadas diferenças entre as freqüências de manifestações bucais, das categorias de imunossupressão e da carga viral. O quadro de manifestações bucais no grupo de crianças e adolescentes acompanhados neste estudo manteve-se estável, mesmo após a introdução da terapia anti-retroviral combinada. Contudo, foi observada uma tendência de diminuição da freqüência de candidíase bucal e hipertrofia de parótidas.

Imunoglobulinas salivares e sua relaçäo com cárie e imunossupressäo em crianças infectadas pelo HIV / Salivary immunoglobulins and its correlation with dental caries and immunessupression in HIV infected children

O objetivo do presente estudo foi determinar a prevalência de cárie em crianças infectadas pelo HIV (HIV+) comparando com um grupo controle de crianças sem sinais de imunodeficiência e observar suas correlaçöes com níveis salivares s Streptococcus mutans, Streptococcus sobrinus e Lactobacillus acidophilus e níveis de anticorpos salivares (IgA total e IgA específica pasa S. mutans, S. sobrinus e L. acidophilus). Correlaçöes entre estes parâmetros e a classificaçäo clínica e imunológica das crianças HIV+ também foram investigadas. A cárie foi quantificada pelos índices ceo e ceo-s e após coleta de saliva estimulada, os níveis das bactérias cariogênicas determinados pela técnica do "Checkerboard DNA-DNA hybridization", e os anticorpos medidos através de "enzyme linked immunosorbant assays". A prevalência de cárie foi maior para as crianças HIV+ (p<0,05) e a quantidade de microorganismos cariogênicos e anticorpos salivares semelhantes nos dois grupos, com exceçäo da IgA total que apresentou níveis mais elevados no grupo HIV+ (p<0,05). Embora näo estatisticamente significante, a prevalência de cárie e a quantidade de S. mutans nas crianças HIV+ foram maiores nas mais comprometidas clínica e imunologicamente. Os níveis de IgA (total e específica) também cresceram com a piora do quadro clínico das cianças HIV+, porém reduziram no estágio mais grave (AIDS). Quando observado somente os indivíduos mais imunologicamente comprometidos, as crianças mais infectadas pelo S. mutans e com maior prevalência de cárie apresentram níveis menores de imunoglobulinas. Os resultados indicam que a resposta do sistema imune mucoso a bactérias cariogênicas permanece intacta nas crianças HIV+, até que a AIDS se instale
