“…Attention is drawn to the microgeometrical characteristics, which, in contrast to the mechanical properties, practically do not change, amounting to 151.3 ± 3 nm. It is well established that some factors can affect the roughness of cementum, such as acidic beverages [47] or polishing techniques applied by the dental clinician [48]. In this regard, the latter observation provides a basis for further ex vivo studies of either cementum alteration under certain conditions or efficacy of dental treatments on recovery of the natural roughness parameters.…”

In the present research, nanoindentation, atomic-force microscopy and optical microscopy were used to study the mechanical and microgeometrical parameters of tooth tissues. A nanoindentation test unit equipped with Berkovich indenter was used to determine the values of the reduced Young’s modulus and indentation hardness and both nanoindentation and atomic force microscopy using a diamond probe on a silicon cantilever were used to study microgeometrical parameters of human tooth root cementum. Three areas of cementum were studied: the cervical region near the dentine–enamel junction, the second third of the tooth root, and the apex of the tooth root. The interpretation of the results was carried out using the Oliver–Pharr method. It was established, that the mechanical properties of cementum increase from the cervical region to the central part of the root, then decrease again towards the apex of the tooth root. On the contrary, the microgeometrical characteristics of cementum practically do not demonstrate any change in the same direction. A decrease in the roughness parameters in the direction from cellular cementum to dentine was observed. Additionally, a decrease in the reduced Young’s modulus and indentation hardness of dentine in the cervical area compared to dentine in the crown part of the tooth was found using nanoindentation. The investigation of the dentine–cementum junction with high resolution revealed the interspaced collagen fiber bridges and epithelial rests of Malassez, whose sizes were studied. The parameters of the topographic features of the cementum in the vicinity of the lacunae of cementocytes were also established.

“…In the literature, it has been observed that different methods are used to evaluate the roughness of different applications on dental tissues and restorative materials. When the literature is reviewed, it was seen that there are many studies [15][16][17][18][19] examining the surface roughness with SEM [20][21][22][23] and pro lometer. However, studies with AFM are very few.…”

Recurrent tooth discoloration due to the increase in roughness after polishing is a concern for patients and dentists. This study evaluated the surface roughness of primary molars after different polishing methods through atomic force microscopy (AFM). A total of 88 primary teeth were randomly assigned to 4 groups, 22 teeth in each group. Before polishing, roughness measurements and visualizations were performed with AFM. The teeth were polished with four different polishing pastes (Imipomza®, Septodent Détartrine®, Kerr Cleanic®, Shofu Mersaage Regular ®) in line with the manufacturer's recommendations. After polishing, average roughness (Ra) values, which express the surface roughness of the re-scanned teeth. The Ra scores were then statistically analysed. In the groups; while there was no significant difference in terms of roughness values (Ra) within the group (p > 0.05), a statistically significant reduction in roughness (Ra) was observed on the sample surfaces after polishing in all groups compared to the baseline (p < 0.05). All polishing methods used in the treatment of primary tooth discoloration can reduce the plaque formation and thus the amount of recoloring by reducing the surface roughness at a similar level.The traditional polishing method (pumice polishing brush), which is more economical and easy to reach, can continue to be used instead of existing polishing pastes in removing discoloration on primary teeth.

“…Yuanli et al ( 2018 ) have noted that different polishing methods have different advantages and disadvantages in terms of four aspects, namely, the plaque index, gingival index, bleeding index, and pigment index, and the method should be selected according to patient pigment deposition, gingival bleeding, and plaque deposition. Chowdhary and Mohan ( 2018 ) compared three polishing methods—brush, rubber cup, and air scrub—by dividing 60 periodontitis‐excised teeth from patients with periodontitis into different enamel and cementum samples. It was concluded that rubber cup polishing has a good polishing effect on both gingival and subgingival surfaces.…”

ObjectiveTo investigate the effects of different polishing methods on the surface microstructure and roughness of teeth following initial periodontal treatment.MethodsTeeth were divided into three groups (silica onegloss, polishing disc, and polishing strip) in vitro. Tooth surface microstructure was characterized via scanning electron microscopy. Roughness was measured by profilometry and laser scanning confocal microscopy (LSCM). According to the in vitro results, one group was chosen for further clinical trials. Effects of the chosen polishing method on patient plaque control and satisfaction were assessed via plaque staining and visual analog scale (VAS).ResultsElectron microscopy results revealed that the polishing disc group had smoother roots and crowns than did the other two groups. Roughness analysis revealed that the crown roughness with the polishing disc and silica onegloss was lower, and the root roughness with the polishing disc was the lowest (p < .05) The LSCM results showed that the pigment deposition depth with the polishing disc and silicon onegloss in the crowns and roots were significantly lower than those with the other two methods (p = .000). The polishing effect of the polishing disc was best among the three groups. Clinical trials were performed to verify the polishing disc effects. Plaque staining results showed that the decrease in plaque in the polishing disc group was greater than that of the rubber cup group (p = .020), which was similar to the results of LSCM. The VAS results showed that the polishing disc made teeth feel smoother, similar to the results of the roughness detection, and the procedure was more comfortable (p < .05). However, there was no significant difference between the two groups regarding foreign body sensation during pronunciation (p = .178).ConclusionCombining in vitro and in vivo evaluations, the use of a polishing disc following periodontal treatment yielded superior polishing effects on teeth and was better accepted by patients.
