“…A similar temperature drop was also observed in another in vivo study evaluating the temperature of a preparation pulpal floor [18]. Conversely, in vitro studies reported significant temperature increase within the pulp chamber, ranging from 5.9 • C to 11.7 • C, during cavity preparation, because of the changes in the air pressure and water flow from the high-speed handpiece [27,28]. In those studies, no pulpal microcirculation was simulated and a decrease in temperature was only noted when the highest water flow rate was used along with the high-speed handpiece [27].…”

“…Ultrasonic devices are a good alternative, since they do not produce the high-pitched sound that annoys patients; provides better access to cavities and cavity cleaning; demonstrates lower wear of the tips during use; causes less patient discomfort, vibration, sensation of pressure and heat; and are less expensive than lasers. 13 Further in vitro and in vivo studies are required to come to a definite conclusion.…”

BackgroundCaries excavation is a noninvasive technique of caries removal with maximum preservation of healthy tooth structure.AimTo compare the efficacy of three different caries excavation techniques in reducing the count of cariogenic flora.Materials and methodsSixty healthy primary molars were selected from 26 healthy children with occlusal carious lesions without pulpal involvement and divided into three groups in which caries excavation was done with the help of (1) carbide bur; (2) polymer bur using slow-speed handpiece; and (3) ultrasonic tip with ultrasonic machine. Samples were collected before and after caries excavation for microbiological analysis with the help of sterile sharp spoon excavator. Samples were inoculated on blood agar plate and incubated at 37°C for 48 hours. After bacterial cultivation, the bacterial count of Streptococcus mutans was obtained.Statistical analysisAll statistical analysis was performed using SPSS 13 statistical software version. Kruskal-Wallis analysis of variance, Wilcoxon matched pairs test, and Z test were performed to reveal the statistical significance.ResultsThe decrease in bacterial count of S. mutans before and after caries excavation was significant (p < 0.001) in all the three groups.ConclusionCarbide bur showed most efficient reduction in cariogenic flora, while ultrasonic tip showed almost comparable results, while polymer bur showed least reduction in cariogenic flora after caries excavation.How to cite this articleHassan AF, Yadav G, Tripathi AM, Mehrotra M, Saha S, Garg N.

“…Ultrasonic instruments are largely atraumatic to the gingival attachment, pulp, and adjacent teeth. 4,5 Esthetic restorations in the anterior dentition often demand a preparation with a subgingival finish line. 4 The oscillating action of ultrasonic instruments reduces trauma to the soft tissues during subgingival margin preparation, facilitating accurate impression taking.…”
