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.

“…[61,62,52] Using higher operation power than the recommended, to speed up the cutting effect and reduce the preparation time, can result in an increased cavity size, vibration rate, and noise, leading to patient discomfort. [63,64] New tips with an enhanced diamond layer, in which a mixture of methane and hydrogen gases form a single artificial layer, improve cutting efficiency. [61] RCTs, case series, and case-control studies and systematic reviews must be made, taking into account, differences in tip design, quality, and the duration of diamond layers on tips and the quality of substance removed or shaped with OIs.…”

Oscillating diamond instruments are considered gentle sources for the removal of demineralized tooth hard tissues and the preparation of cavity angles and margins needed in minimally invasive dentistry. However, there is a question if literature provides enough evidence for their efficacy in restorative dentistry procedures. A literature search until May 2016 was conducted, using PubMed, Scopus, and The Cochrane Central Register of Controlled Trials databases. The quality of the studies was assessed using the recommendation of the Oxford Centre for Evidence-based Medicine. Fifty-five studies were finally included in the study. Of which, 78.2% of them were laboratory studies and only 21.8% were clinical studies. The strength of recommendation was 5 for most of them and D their grade of evidence. Bond strength of adhesives on surfaces prepared with these instruments, effective caries removal and cutting characteristics of the oscillating instruments were the main targets of the studies. Conventional diamond, steel, and chemical vapor deposition diamond tips and systems based on abrasive slurry were the oscillating tips, used in different studies. The strength of recommendation and grade of evidence of the studies were low. Although these devices seem to be useful for many clinical situations, there is a need for more well-structured evidence-based studies with more widely accepted procedures and common devices, to have more meaningful results and conclusions of higher strength.

Margin quality of cavity preparations with different techniques and instruments For more than 40 years, dentistry has used the same technology for cavity preparation, high-speed rotation systems with diamond burs. New studies and techniques have been performed to develop a new treatment option for patients. Thus, new technologies have been possible such as high pressure sandblasting systems, laser devices, multiplying low-speed rotation, and finally, the ultra-sound with diamond burs. However, whether these new technologies can be an alternative or substitute for old practices with standard results is not known. The aim of this study was to evaluate by SEM cavity preparation margins with and without finishing, made by diamond burs and the CVDentus system associated to different devices and action forms. The results showed no statistically significant differences (p<.05) among the tested conditions on individual comparisons, except for GIV x GVII (highspeed rotation plus diamond bur + low-speed rotation plus diamond finishing bur x ultra-sound plus CVDentus 50% power plus low-speed rotation). It was concluded that all finishing modes on margin cavities are reliable and can be used in clinical practice. The use of the ultra-sound device can be recommended within 50-75% power for cavity preparations.
