In vivo morphological and clinical effects of a desensitizing agent

2010

Objectives: This study evaluated the in vivo effectiveness of Universal Dentin Sealant (UDS), a new resin-based material, as dentinal desensitizing agent on dentin morphology and clinical symptoms. Materials and methods: Thirty premolars, exhibiting non-carious cervical lesions, and scheduled for extraction for periodontal reasons, were selected for the ultrastructural study. These samples were randomly divided into three groups ( n = 10): group 1, brushing with UDS; group 2, brushing with Flor-Opal ® Varnish (FOV); and group 3, untreated control. After 7 days, teeth were extracted and samples processed for SEM and TEM comparative observations. The in vivo study was carried out on 90 teeth …

Evaluation of the enamel etching pattern of self-etching adhesives

2010

Objectives: To evaluate the capacity of seven self-etching adhesives (SEAs) to demineralize ground enamel in comparison with traditional phosphoric acid etchant (PAE) using SEM and statistical analysis. Materials and methods: 80 caries-free extracted human third molars were divided into 8 groups ( n = 10). Enamel bur-cut surfaces were prepared and, strictly following the manufacturers’ instructions, treated with three priming agents of two-step self-etching adhesives: Aqua Resulcin Prime (Group 1); Peak™ (Group 2); Clearfil Protect Bond (Group 3); four one-step self-etch (all-in-one) adhesives, G-Bond (Group 4); Artegral One (Group 5); Clearfil S3 Bond (Group 6); Adper Easy Bond (Group 7); …

Short-term response of three resin-based materials as desensitizing agents under oral environmental exposure

2012

Objective. This paper focuses on clinical responses after 7 days of oral exposure to two resin-based materials as desensitizing agents compared to a fluoride varnish and on morphological and analytical study as a means to elucidate the mechanism of action. Materials and methods. The elemental composition of Vertise™ Flow (VF), Universal Dentine Sealant (UDS) and Flor-Opal® Varnish (FOV) were investigated by using an X-ray energy dispersive spectrometer (EDX) in conjunction with a scanning electron microscope (SEM). SEM morphology of the material-treated dentine surfaces and pain reduction ability according to the Visual Analogue Scale (VAS) were evaluated in selected hypersensitive teeth. P…
