“…Li et al 16 found that during the first month of fixed orthodontic treatment, the whole saliva flow rate and concentrations of some saliva ions increased significantly, but were at normal levels after 3 months. Sanpei et al 17 found changes in salivary Lactobacillus spp levels but no changes in salivary flow rates, buffer capacity, and S mutans levels during and after active orthodontic treatment.…”

Objective: To determine the physiologic changes of salivary flow rate, pH, and buffer capacity and the levels of Streptococcus mutans and Lactobacillus spp in patients undergoing fixed orthodontic treatment. Materials and Methods: The study included 23 patients scheduled for fixed orthodontic therapy. All subjects received equal braces, bands, and brackets, bonded with the same material. Stimulated saliva samples were taken before placement of the appliance, and at weeks 6, 12, and 18 during the therapy. Salivary flow rate and salivary pH were measured, and the salivary buffer capacity was determined. Saliva samples were cultivated on selective microbial agar for microorganism detection. Results: A significant (P , .05) increase in stimulated salivary flow rate and salivary pH was found. The salivary levels of S mutans and Lactobacillus spp also inscreased significantly (P , .05), and the major peak was at week 12 of fixed orthodontic therapy. Conclusion: The 6th to 12th week of orthodontic therapy is the period of the most intensive intraoral growth of S mutans and Lactobacillus spp and a time of very intensive salivary functions and physiologic response.

“…The development of WSLs is a challenging problem in the course of orthodontic treatment. Especially in fixed orthodontic treatment, plaque accumulation increases around brackets and bands (3) and the pH on dental surfaces becomes acidic (4). The Streptococcus mutans (MS) and Lactobacillus (LS) populations in the plaque over the tooth surface increase and these microorganisms can cause enamel demineralization via organic acid production in the plaque (5,6).…”

Non-Cavitated Approach for the Treatment of White Spot Lesions: A Case Report

2017

Aim: White spot lesions (WSLs) are the most frequently observed problems in patients with poor oral hygiene. If this problem is left untreated during the initial phase, it will ultimately need major treatment. One treatment alternative in the initial phase is the caries infiltration technique. The aim of this case report is to present the treatment of WSLs by using this technique. Methodology: An 18-year-old female who had WSLs on the buccal surfaces of the lower left canine, first and second premolars and first molar after 8 months of fixed orthodontic therapy was included in this study. Icon-Infiltrant was applied for the treatment of WSLs. Results: After Icon-Infiltrant application, the WSLs were cured. Conclusions: By using this technique, an esthetic smile can be achieved in one visit with the elimination of esthetic discoloration and the progression of the early enamel lesions can be prevented.

Espécies de Candida ssp também interagem com S. mutans e Lactobacillus, favorecendo a criação de um micro-ambiente com pH ácido (Metwalli et al, 2013;Falsetta et al, 2014) O acúmulo de biofilme sobre a superfície dental e seu desenvolvimento ao longo do tempo, também ocasiona inflamação dos tecidos periodontais, podendo conduzir à instalação da gengivite e da periodontite (Socransky et al, 1998;Huang e Artun, 2001;Socransky et al, 2002;Socransky e Haffajee, 2005;Naranjo et al, 2006;Sudjalim et al, 2007;Lang et al, 2009), principalmente na presença de micro-organismos anaeróbios Gramnegativos periodontopatogênicos (Socransky e Haffajee, 2005;Slots e Slots, 2011).…”

CAPÍTULO 4 75Níveis de citocinas no fluido crevicular e perfil microbiano in situ, após a colagem de bráquetes convencionais e autoligados. ® R e SmartClip TM em incisivos e caninos superiores. Os índices, o volume do fluido e as amostra de saliva (S0) foram obtidos antes da instalação dos aparelhos (T0) e após 30(T1) e 60(T2) dias. Um bráquete de cada tipo foi removido 30 e 60 dias após a colagem. Os dados foram submetidos à análise estatística utilizando-se os testes não-paramétricos de Friedman, Mann-Whitney e Wilcoxon e coeficiente de correlação não-paramétrico de Spearman. A análise da concentração de citocinas no fluido crevicular foi realizada segundo modelo de análise de variância misto, seguida pelo teste de Tukey, com nível de significância de 5%. Não houve correlação entre o grau de apinhamento, overjet e overbite com os escores do índice de placa (PI), índice gengival, índice de sangramento gengival e com o volume do fluido crevicular no tempo inicial T0 (p>0,05). Verificou-se a diferença significativa nos escores de PI e volume do fluido crevicular somente nos dentes que receberam bráquetes autoligados SmartClip TM , entre os tempos T0-T2(p<0,05). Identificou-se a presença de 21 das 22 espécies bacterianas e 4 das 5 espécies fúngicas, na saliva, antes da colagem dos aparelhos ortodônticos. In situ, no bráquete autoligado SmartClip TM observou-se maiores níveis de espécies do complexo vermelho 60 dias após a colagem. Para os bráquetes convencionais Gemini TM verificou-se diminuição nos níveis de espécies do complexo roxo. Para o bráquete autoligado In-Ovation ® R identificou-se diferença significativa para C. rectus 30 dias após a colagem e para S. mutans 60 dias após a colagem. Quando comparou-se os níveis salivares e os in situ, verificou-se maiores níveis de espécies nos bráquetes, in situ, sendo que os autoligados apresentaram os maiores valores.Aumento significante foi verificado para os bráquetes autoligados In-Ovation ® R, para S. mutans e L. casei. Após 60 dias da colagem do aparelho ortodôntico observou-se um aumento nos níveis de TNF-α (p<0.005), em todos os tipos de bráquetes.
