Este estudo investigou o processo de necrose, o nível de proliferação celular (imunomarcação com PCNA) e apoptose (Caspase-3-clivada), e a resposta imune inflamatória (IL-17, IL-6 e CD5) no tecido pulpar após este procedimento. Foram utilizados dois protocolos de clareação dentária com peróxido de hidrogênio (H2O2) nos molares superiores de 40 ratos Wistar, formando os grupos Controle (gel placebo), BLUE (H2O2 a 20% 1x50min) e MAXX (H2O2 a 35%, 3x15min). Após 2 e 30 dias, os ratos foram eutanasiados e as maxilas processadas para avaliação histológica (H.E.) e imunoistoquímica. Foram realizados os testes estatísticos referentes a cada caso, considerando p<0,05. Aos dois dias, foi observada necrose no terço oclusal do grupo MAXX, e infiltrado inflamatório moderado no BLUE (p<0,05). Aos 30 dias, não houve infiltrado inflamatório nos grupos, e grande área da câmara pulpar foi ocupada por dentina terciária. A marcação para PCNA aos 2 dias, demonstrou maior nível de proliferação celular no terço médio do grupo BLUE (p<0,05) e no terço cervical do MAXX (p<0,05), com redução significativa aos 30 dias no terço cervical (p<0,05). Caspase-3-clivada foi presente em todos os grupos, apresentando maior nível de apoptose nos grupos clareados quando comparados com o controle, nos dois períodos de análise (p<0,05); quando comparados os grupos aos 2 e 30 dias, foi observada redução significativa do nível de apoptose apenas no grupo BLUE (p<0,05). Células CD5 positivas foram presentes em todos os grupos, em ambos períodos de análise; aos dois dias, o grupo BLUE apresentou maior imunomarcação para CD5 no terço oclusal quando comparado aos demais grupos (p<0,05); nos demais terços... / Studies have shown damage to tooth pulp, and your capacity of tissue repair, after dental bleaching. This study investigated the necrosis process, the level of cell proliferation (immunolabeling with PCNA) and apoptosis (Caspase-3, cleaved), and inflammatory response (IL-17, IL-6 and CD5) generated in the pulp tissue after this procedure. Wistar rats were divided into Control (placebo gel), BLUE (20% H2O2,1x50min), and MAXX (35% H2O2, 3x15min) groups. At 2 and 30 days, the rats were killed (n=10).The jaws were removed and processed for histology analysis (H&E) and immunohistochemistry. Statistical tests were performed for each case, considering p<0.05. At two days, necrosis was observed on the occlusal third MAXX group and moderate inflammatory infiltrate in BLUE (p<0.05). At 30 days, there was no inflammatory infiltrate in groups, and large area of the pulp chamber was occupied by tertiary dentin. The immunolabeling for PCNA, at two days, was more expressive in the middle third of the BLUE group (p<0.05) and the cervical third of the MAXX (p<0.05), with significant reduction to 30 days in the cervical third (p<0.05). Caspase-3-cleaved was present in all groups, showing a higher level of apoptosis in the bleached groups compared with the control in both analysis periods (p<0.05); comparing the groups at 2 and 30 days, significant reduction in the level of apoptosis was observed only in BLUE group (p<0.05). CD5 positive cells were found in all groups in both analysis periods; at two days, the BLUE group had higher immunolabeling for CD5 in the occlusal third when compared to the other groups (p<0.05); in other thirds, both groups bleached showed most immunolabeling compared with the control group (p<0.05); there was no significant difference in the comparison of each group at 2 and 30 days (p>0.05).

Diante disso, o objetivo deste trabalho foi avaliar in situ, in vivo e in vitro a relação da bactéria probiótica com a cárie dentária. No estudo in situ investigou-se a cariogenicidade do leite fermentado contendo probióticos através da quantificação dos açúcares totais e redutores presente no produto, análise do seu efeito na desmineralização do esmalte dental bovino, análise microbiológica da saliva antes e após o período experimental, análise microbiológica e quantificação dos carboidratos álcalis-solúveis presente no biofilme. Para isso, dez voluntários utilizaram um dispositivos contendo 4 blocos de esmalte dental bovino. O experimento consistiu de 3 etapas de 14 dias cada onde os voluntários gotejaram solução de sacarose 20% ou a solução de tratamento (Tratamento A - Yakult® ou Tratamento B - Batavito®) 8X/dia. Decorrido o período experimental, o biofilme e a saliva foram analisados quanto a quantidade de microrganismos totais (MT), Streptococcus totais (ST) e Streptococcus do grupo mutans (SM), Lactobacillus (L). Para os dados de dureza foram calculados a porcentagem de variação de dureza superficial e a perda integrada de dureza de subsuperfície. Após o tratamento B foi observado menor quantidade de MT no biofilme quando comparado com o tratamento A, mas não diferiu da solução de sacarose 20%. Na saliva, o tratamento com solução de sacarose 20% diminuiu a quantidade de MT e ST, e aumento a quantidade de SM. O tratamento A provocou uma diminuição na quantidade de MT, ST e SM e o tratamento B diminuiu a quantidade de MT. Para os dados... / Probiotics are live microorganisms, which when administered in adequate amounts, confer a health benefit on the host. An increasing number of probiotic-containing products are available, and these products have been orally consumed. However, the objective of this study was to evaluate in situ, in vivo and in vitro the relation between probiotic bacteria and dental caries. In the in situ and in vivo study it was evaluate the effect of 2 probiotic-containing fermented milk on biofilm and saliva microorganisms and on enamel surface. The in situ study was performed in 3 phases: 20% sucrose, treatment A (Yakult®) and treatment B (Batavito®). Salivary microorganisms were counted at baseline and after and biofilm was analyzed just after the trial period. In vivo study was performed in 2 phases: treatment C (Yakult®) and treatment D (Batavito®). The saliva was collected at baseline and at the end of the trial period for microbiological analysis. In the in situ study, biofilm data showed less total microorganisms (TM) after treatment B than treatment A but similar to 20% sucrose. In the saliva, 20% sucrose decreased TM and total streptococci (TS), and increased mutans streptococci (MS). Treatment A significantly decreased TM, TS and MS. Treatment B decreased TM. It was observed less MS in treatment B when the final data were compared among the treatments. Treatment B differed from the other treatments in relation to final microhardness, percentage change of surface hardness and integrated loss of subsurface hardness (p<0.05). In vivo study showed that just treatment D decreased all microorganisms. It was observed higher lactobacilli (L) in treatment D when the baseline data were compared among the groups. In the in vitro study, it was determined the ability of probiotic bacteria to prevent primary caries development... (Complete abstract click electronic access below)
