Zusammenfassung: | <jats:title>Abstract</jats:title><jats:p>This <jats:italic>in situ</jats:italic> study evaluated the tubular occlusion caused by 4% TiF<jats:sub>4</jats:sub> gel on the surface of eroded/abraded dentin. Sixty human dentin samples were eroded <jats:italic>in vitro</jats:italic> and assigned into six groups (<jats:italic>n</jats:italic> = 10) according to the <jats:italic>in situ</jats:italic> surface treatment and number of cycling days: 4% TiF<jats:sub>4</jats:sub> gel applied once (TiF<jats:sub>4</jats:sub>1), twice (TiF<jats:sub>4</jats:sub>2), or three times (TiF<jats:sub>4</jats:sub>3) followed by 2, 4, and 6 days of erosive/abrasive <jats:italic>in situ</jats:italic> cycling, respectively. Control groups (no treatment) were subjected to 2 (C1), 4 (C2), and 6 (C3) days of erosive/abrasive <jats:italic>in situ</jats:italic> cycling only. A seventh group (<jats:italic>n</jats:italic> = 10) was comprised by <jats:italic>in vitro</jats:italic> uneroded samples (UN), subjected to 6 days of <jats:italic>in situ</jats:italic> erosive/abrasive cycling. Each cycling day consisted on six erosive (0.5% citric acid, pH 2.6) and one abrasive events. Environmental scanning electron microscopy micrographs were taken. For all groups, blinded examiners assessed dentin tubules occlusion using visual scores (0—unoccluded, 1—partially occluded by granular deposits, 2—partially occluded by reduction in tubular lumen into diamond shape, 3—completely occluded) on images captured prior and after the <jats:italic>in situ</jats:italic> phase. Scheirer‐Ray‐Hare test demonstrated that treatments significantly affected tubule occlusion (<jats:italic>p</jats:italic> < .001). Dunn's test showed that tubule occlusion in TiF<jats:sub>4</jats:sub>3 was significantly higher than in C1. Tubule occlusion in remaining groups did not differ from that observed in groups TiF<jats:sub>4</jats:sub>3 and C1. Tubule occlusion was significantly higher after <jats:italic>in situ</jats:italic> phase. It may be suggested that TiF<jats:sub>4</jats:sub>, when applied three times, was able to positively change tubule occlusion of dentin samples.</jats:p> |
