BACKGROUND Objective was to evaluate the in vivo effects of a novel dental gel (Livionex gelR) vs. a comparison dental gel on the surfaces of pre-eroded enamel chips. METHODS On days 1-5, after toothbrushing with dentifrice, nine subjects each wore 8 enamel chips mounted on a palatal appliance for 4 h. Enamel blocks were pre-demineralized daily. After 2 day washout, subjects repeated the prot...

Our teeth are constantly subjected to erosion caused by the action of food and drinks (1). These aggressions result in the exposure of dentinal tubules and the underlying nerves to the external environment. Consequently, external stimuli trigger the nerves causing a short and acute pain clinically defined as dental hypersensitivity (2). Individuals with this condition present tooth with open de...

Background: The fluoride drug is mentioned as a double-edged weapon due to its positive and negative outcomes. Reducing dental caries in large population, cost effective excess teeth or body may lead systemic diseases even death. Dental erosion affects the hard tissues of rendering them vulnerable decay. Methods & Materials: A school based descriptive cross-sectional survey. Purposive sampl...

objective: oral iron drops are recommended for children aged 6-24 months to prevent iron-deficiency anemia. however, their use is associated with the potential risk of erosion and microhardness reduction of primary teeth enamel due to their high acidity. it seems that the combination of silicone oil, nano-hydroxyapatite and chitosan powder may be able to improve the microhardness and surface st...

Oral health is related to diet in many ways, for example, nutritional influences on craniofacial development, oral cancer and oral infectious diseases. Dental diseases impact considerably on self-esteem and quality of life and are expensive to treat. The objective of this paper is to review the evidence for an association between nutrition, diet and dental diseases and to present dietary recomm...

Objective The prevalence of dental erosion has been recently increasing, requiring new preventive and therapeutic approaches. Vegetable oils have been studied in preventive dentistry because they come from a natural, edible, low-cost, and worldwide accessible source. This study aimed to evaluate the protective effect of different vegetable oils, applied in two concentrations, on initial enamel ...

OBJECTIVES This randomised in situ study aimed to analyse the effect of milk (with or without 5ppm F) and CPP-ACP pastes (with or without 900ppm F) on dental erosion. METHODS The study was a seven phase (5 days each) crossover design involving 15 participants wearing intraoral appliances with enamel and dentine specimens. Specimens were extraorally eroded (erosive soft drink, 6×90s/day) and bru...

BACKGROUND Children with congenital heart defects (CHD) are reported to have poorer oral health compared with healthy children. The aim of the present study was to evaluate the effectiveness of an intensive oral health care program among children with CHD followed from infancy to the age of 5 years, by comparing their oral health status at 5 years with a control group of children with CHD who h...
