Assessment of oxidative stress in saliva of children with dental erosion

Abstract

Objective To evaluate oxidative stress in saliva of children with dental erosion as compared to children with no erosion.Methods One single examiner, trained and prepared to make diagnosis of dental erosion according to the Basic Erosive Wear Examination index, selected 40 children aged 4 to 6 years, who attended a pediatric dentistry prevention clinic. Two groups were formed - one comprising children with dental erosion (n=22), and another with no dental erosion (n=18). The quantity of dental biofilm was verified using the Simplified Index of Oral Hygiene, and unstimulated saliva was collected for biochemical analyses. The following were assessed in saliva: flow rate, buffering capacity, pH, and total protein concentration. Malondialdehyde levels were also verified to determine oxidative stress and total antioxidant status.Results The quantity of biofilm was smaller in children with mean dental erosion±standard deviation (0.76±0.25), as compared to those with no dental erosion (1.18±0.28). There was no statistical difference in saliva parameters of oxidative stress in children with dental erosion.Conclusion The activity of oxidative stress in saliva did not influence dental erosion process when in its early stages.

The link between nutrition and dental erosion: what do students know?

“…Dental erosion, irreversible mineral and superficial tooth loss due to non-bacterial chemical or electrochemical processes, is a significant problem for children and adolescents (Shitsuka et al , 2018; Shitsuka et al , 2016). Dental erosion is hard dental tissue loss that does not involve microorganisms and, in that sense, it differs from dental caries (Kanzow et al , 2016; Struzycka et al , 2016; Carvalho et al , 2015).…”

“…The etiology is multifactorial, and both the etiology and severity depend on various patient-related and nutritional factors (Kanzow et al , 2016; Lussi et al , 2011). Although the etiology is multifactorial, the process usually occurs with endogenous and exogenous acidic sources (Lussi, 2006; Shitsuka et al , 2018). Patients with gastroesophageal reflux, eating disorders, chronic alcohol dependency, special diets including a raw food diet, high consumption of soft or sports drinks and patients with regular medicine intake have increased risk (Struzycka et al , 2016).…”

Prevalence of Dental Erosion among Children aged 11-12 years Old in Primary Schools at Sammawa City(South of Iraq)

“…The salivary flow rate and PH of saliva were lower in study group compared to control group and in boys lower than girls, which clarified the cause of the development of dental erosion because un stimulated saliva plays a very important role in protecting the teeth from wear (18) , in addition , the low acidic PH of saliva in the study group causes the development of dental erosion , which agrees with other studies in this part (15,16,17) that when PH of saliva decreases, it will cross the point of saturation at a point called critical PH which causes the demineralization of the teeth (10) .…”

Percepção Dos Auxiliares E Técnicos Em Saúde Bucal Da Atenção Primária Sobre a Política De Educação Permanente Em Saúde

“…A quimioterapia foi o tratamento antineoplásico mais prevalente na presente pesquisa, contabilizando 50 pacientes, também sendo mencionado, em vários estudos, como o principal tratamento para o câncer (ALBERTH et al, 2004;AVŞAR et al, 2007;HONG et al, 2010;NEMETH et al, 2013 Os dentes possuem muitas propriedades físico-quimicas que desempenham funções especificas, como as de proteção da estrutura dentaria, diluição de substancias acidas erosivas na cavidade oral por meio do fluxo salivar, neutralização e tamponamento dos ácidos pelo ph e também o fornecimento de íon de cálcio e fosfato, agindo assim contra a erosão dentária. (SHITSUKA, 2018). Além do combate a erosão, a capacidade de tamponamento presente na saliva, é um fator imprescindível que viabiliza maior resistência ao dente contra as etiologias multifatoriais que providenciam a cárie (PORCARO BRETAS et al, 2008 (CARRILLO et al, 2010;VOLPATO et al, 2016;VELTEN et al, 2017;INCA, 2018).…”
