“…Also, the grit size and concentration are not factors. It also should be noted that vibrations during clinical finishing using highspeed turbine dental handpieces (Poole et al, 2008) could have a significant effect on removal rate and perhaps edge chipping.…”

“…Therefore, there is still a lot of ongoing research on this appliance. Recent studies mainly focused on evaluating the cutting performance of handpieces with different restorative materials [1,2] and their driving forces, such as air or electricity [3,4], and they performed assessments to reduce noise and vibration [5]. However, few studies have explored the cause of performance differences among the high-speed dental handpieces.…”

This study aimed to evaluate the correlation between the cutting efficiency and bur eccentricity of high-speed handpieces. The prepared lithium disilicate samples were digitized using a 3D model scanner (reference model, RM) (n = 45), and the lithium disilicate samples were cut using three high-speed handpieces. To evaluate the cutting efficiency, the cut lithium disilicate sample was digitized (cutting model, CM), and the RM and CM were superimposed using a 3D analysis software. Bur eccentricity of the high-speed handpieces was measured using dedicated equipment. Statistical analyses were performed using an analysis software. The statistical differences in pairwise comparisons (α = 0.05) were analyzed using the Kruskal–Wallis and post hoc tests. The S-max M600 obtained a cutting efficiency of 6.13 mm3. TG-98 and TRAUS ATN-400 showed similar efficiencies of 2.914 and 3.05 mm3, respectively. There was a significant difference in the cutting efficiency of the S-max M600 compared with TG-98 and TRAUS ATN-400 (p < 0.001). S-max M600 had an eccentricity of 3.507 µm. TG-98 and TRAUS ATN-400 had eccentricities of 5.99 and 7.767 µm, respectively. There were statistically significant differences in the eccentricity among all the high-speed handpieces (p < 0.001).

“…The vibrations and noise generated by dental equipment have a cumulative effect on both patient and dentist, causing anxiety and stress 1,25 . This stress was reported to be the cause of higher post‐operative adrenaline levels especially in uncooperative patients compared to cooperative patients, 26 necessitating awareness and further research on patients' anxiety levels 2 .…”

Background The vibrations created by post‐space preparation during the first visit for endodontic treatment could have a significant effect on the intensity of post‐operative pain than that association with post‐space preparation at the second appointment. Objective The aim of this study was to evaluate the effect of vibrations generated during post‐installation, on post‐operative pain in endodontically treated teeth. Methods One hundred patients with asymptomatic teeth requiring primary root canal treatment and post‐installation were enrolled in this study. Fifty patients underwent endodontic treatment with post‐installation at the first visit (group 1), while the remaining 50 patients underwent post‐installation at the second visit (group 2). The intensity of post‐operative pain in both groups was evaluated 1, 2, 3 days and 1 week after the first visit using the visual analogue scale. The time required to achieve complete pain relief for each patient was also recorded. The patients' age, sex, tooth type, size of the periapical lesion and time required for complete post‐operative pain relief for each tooth were recorded. Results The pain intensity score was significantly higher in group 1 than group 2 (P < .05). No significant differences were observed in parameters such as sex, tooth type, jaw and size of the periapical lesion (P > .05), whereas age had a significant effect on the post‐operative pain scores (P < .05). Conclusion Vibrations occurring during post‐installation on the same visit as that of root canal filling may increase the post‐operative pain.
