The aim of this comparative clinical study was to evaluate a novel bioactive glass-ceramic (Biosilicate® 1-20 μm particles) to treat dentine hypersensitivity (DH). Volunteers (n = 120 patients/ 230 teeth) received the following treatments: G1-Sensodyne® , G2-SensiKill®, G3-Biosilicate® incorporated in a 1% water-free-gel and G4-Biosilicate® mixed with(More)
Dentin hypersensitivity (DH) is a painful response to stimulus applied to the open dentinal tubules of a vital tooth. It's a common oral condition, however, without an ideal treatment available yet. This work evaluated in vitro the effect of micron-sized particles from a novel bioactive glass-ceramic (Biosilicate) in occluding open dentinal tubules. A(More)
OBJECTIVES To study the physical properties of two experimental dentifrices for complete denture hygiene, their effect on denture biofilm removal and antimicrobial properties by means of a clinical trial. MATERIALS AND METHODS The experimental dentifrices comprised two compositions. One was based on the addition of 1% chloramine T (D1) and the other on(More)
PURPOSE This study aimed to compare dental plaque removal efficacy of three manual toothbrushes. MATERIALS AND METHODS Three toothbrushes (Colgate Flexível - Colgate (T1), Oral B Advantage Control Grip - Oral B (T2), Comfort Clean - Johnson & Johnson - Reach (T3) were evaluated for dental plaque removal in 17 subjects. Dental plaque was scored before and(More)
OBJECTIVE To analyze the expression and distribution patterns of mature dendritic cells (mDCs) and immature DCs (imDCs) in radicular cysts (RCs), dentigerous cysts (DtCs), and keratocystic odontogenic tumors (KCOTs). MATERIALS AND METHODS Forty-nine odontogenic cystic lesions (OCLs) (RCs, n = 20; DtCs, n = 15; KCOTs, n = 14) were assessed using the(More)
OBJECTIVES To evaluate the impact of audience response systems (ARS) on student participation (SP) during Oral and Maxillofacial Radiology (OMR) undergraduate lectures and on final examination scores (FES). Furthermore, an analysis of unanimity assessed the influence of ARS on students' responses. Students' perceptions were also assessed. METHODS A(More)
PURPOSE The aim of the present study was to evaluate the clinical efficacy of an experimental dentifrice (CH) containing an antimicrobial agent (1% chloramine-T). MATERIALS AND METHODS A clinical, fully randomised, double-blind comparative study was designed for 30 selected patients aged 15 to 50 years, with no periodontal disease, decay or other oral(More)
This study compared the abrasion resistance of direct composite resins cured by light-emitting diodes (LED) and halogen light-curing units. Twenty specimens (12 mm in diameter; 1.0 mm thick) of each composite resin [TPH (Dentsply); Definite (Degussa); Charisma (Heraus Kulzer)] were prepared using a polytetrafluoroethylene matrix. Ten specimens per material(More)
Results: imDCs were more numerous in AgP than ChP and Control groups, being statistically significant only the S100+ cells. Conversely, mDCs were visualized in higher number in ChP than AgP and Control groups (both p<0.05). Considering the frequency of immunostained cells, the number of S100+ cells was greater than CD207+ and CD1a+ cells, followed by a(More)
