Treatment of Dentin Hypersensitivity Using Nano-Hydroxyapatite Pastes: A Randomized Three-Month Clinical Trial

Abstract: Nano-hydroxyapatite formulations (with or without home->care product association) were as effective as the other treatments in reducing dentin hypersensitivity over three months.

“…Hannig and Hannig put these in situ and in vitro findings into a more comprehensive perspective by stating that established physiological tooth wear constantly releases HAP particles into the oral environment, which might subsequently interfere with demineralization and remineralization processes, as well as with the metabolism of the oral microbiota at the tooth‐bacterial biofilm interface . The impact of microcrystalline HAP as an ingredient in dentifrices has been positively evaluated in controlled clinical trials on dentinal hypersensitivity, and parameters of periodontal health . To date, however, comparable data regarding the caries‐inhibiting properties of HAP toothpastes are lacking.…”

“…The existence of these placebo control groups may give additional information about the efficacy of the agents tested, allowing a better interpretation of the results; however, the use of negative controls in DH trials is controversial, since some authors support that, for ethical reasons, treatments without an active ingredient should not be performed. In some of the studies, positive control groups with fluoride dentifrices were used 29,35,46,51,[62][63][64]68,74,81,88,90,92,94. These pastes should not beused as a negative control, as stated by some authors, as they may have different fluorides or other agents, and it is not clear which fluoride concentration is effective in the treatment of DH.…”

“…Os cristais de hidroxiapatita em tamanho nanométrico são semelhantes à morfologia e estrutura da hidroxiapatita dentinária natural e têm sido utilizados em dentifrícios e enxaguantes bucais para reparar a superfície dentária desmineralizada. A hidroxiapatita é considerada como um dos materiais mais biocompatíveis e bioativos devido à sua semelhança com a composição inorgânica do dente facilitando sua interação com o mesmo (GOPINATH et al, 2015;WANG et al, 2016) o que poderia justificar o controle do processo erosivo na dentina neste estudo. Além disso, a penetração profunda das nanopartículas associada ao flúor presente no Desensibilize Nano P parece ser resistente à erosão devido a um imbricamento mecânico da nanohidroxiapatita dentro e/ou sobre os túbulos dentinários (WANG et al, 2016).…”

“…Com relação à avaliação clínica da hipersensibilidade dentinária (HD), não houve diferença entre o grupo tratado com o Desensibilize Nano P e o grupo placebo no qual também houve uma redução na HD. Resultados clínicos positivos também foram descritos com a aplicação do Desensibilize Nano P clinicamente (WANG et al, 2016), porém a literatura é escassa em relação à avaliação in vivo do agente. Um dos fatores que poderia explicar o efeito positivo em ambos os grupos é o efeito placebo que, por ser mediado por mecanismos que envolvem expectativas conscientes e não cognitivas, sua administração causa expectativa de um certo efeito, o que resulta em uma menor resposta à dor (ERDEMIR et al, 2010;ANTONIAZZI et al, 2014).…”
