Influence of one-step professional mechanical tooth cleaning pastes on surface roughness and morphological features of tooth substrates and restoratives

Abstract

This study investigated the influence of professional mechanical tooth cleaning (PMTC) pastes on the surface texture of different subject materials. Methods: Two one-step PMTC pastes, Clinpro Cleaning Paste for PMTC (CP) and PRG Pro-Care Gel (PG), and multiple-step PMTC pastes, Merssage Regular (MR), Merssagge Fine (MF), and Merssage Plus (MP), were used. For comparison, PMTC was performed using distilled water without paste (DW). The subjected materials used were bovine enamel (ENA) and dentin (DEN), a resin composite (FSU), and lithium disilicate (IEC). The prepared specimens were polished using a #2000-grit silicon carbide paper. PMTC was performed using a brush at 1,000 rpm for 15 s. Results: The surface roughness (Ra) values of the specimens before and after PMTC were measured by laser scanning microscopy. The Knoop hardness number (KHN) of the subjected material was obtained. The types of PMTC pastes and subject materials had a significant influence on the Ra values and KHN. For the majority of subject materials, the descending order of Ra values after PMTC was MR > MF > CP > PG > MP > DW. The descending order of KHN of the materials was IEC > ENA > FSU > DEN. Conclusion:Although one-step PMTC pastes appeared to be effective, it is important to consider the subject material during PMTC.

Salivary Pellicle Formed on Dental Composites Evaluated by Mass Spectrometry—An In Situ Study

“…In this context, it is interesting that the composition of a salivary pellicle seems to be more complex on rough surfaces, while at the same time, morphologic irregularities are leveled out [18,37,38]. The observed roughness values are in line with findings that have been already discussed for modern nano-hybrid resin composites (Ra between 30 and 130 nm) [39][40][41][42].…”

In Vitro Comparison of Root Surface Treatment Effect between Root Scaling with Ultrasonic Inserts and Gracey Curette and Polishing with Different Cleaning Pastes

“…Different techniques can determine surface alterations and roughness depending on the time and materials used [11,14]. In clinical situations, supragingival biofilms and subgingival biofilms measuring within 3 mm can be removed mechanically using rotary instruments and a prophylaxis paste [15].…”

“…Numerous studies have evaluated the root surface after periodontal instrumentation with different techniques, such as profilometric analysis [2,11], histological evaluation [2,16] and electron and confocal laser scanning microscopy [15,17,18].…”
