RESUMEN
BACKGROUND: In order to reduce the fear and anxiety of injection during root canal procedures, Madajet injection technique was substituted for the first time among the adult patients to obtain its efficacy and to overcome the painful procedure during the conventional syringe technique. AIM: The aim of this study is to compare the clinical efficacy and level of patient acceptance of jet injections with conventional syringe technique in patients with symptomatic pulpitis. METHODOLOGY: Seventy patients were randomly divided into needleless pressure injection technique using Madajet XL and conventional syringe technique. The onset of anesthesia was evaluated using the electric pulp tester, and the pain was assessed using the Visual Analog Scale scoring criteria. STATISTICAL ANALYSIS: The obtained data were tabulated and subjected to the statistical analysis using the Chi-square test. RESULTS: Needleless pressure injection technique (Madajet XL) proves to be effective in patients with symptomatic irreversible pulpitis during endodontic procedure. CONCLUSION: It can be concluded that the needle-less pressure injection technique (Madajet XL) promises to be a viable mode of pain control during endodontic procedures as it converts the solution to a tiny droplet which is then carried by the myelin sheath.
RESUMEN
BACKGROUND: The principles of minimally invasive dentistry clearly tells us the need for clinically effective measures to remineralize the early enamel caries lesions. AIMS AND OBJECTIVES: The aim of this study was to evaluate the remineralisation potential of four different remineralisation agents used quantitatively by surface microhardness and qualitatively by energy dispersive X ray analysis. MATERIALS AND METHODS: Artificial enamel lesions were created on the buccal surfaces of 60 extracted mandibular second premolar. Specimens were randomly assigned to four groups (n=15) according to the remineralisation agents used: Group 1-Nano Hydroxyapatite, Group 2-Fluoride, Group 3-CPP ACP, Group 4-Chitosan 5mg. All products were applied according to the manufacturer's instructions and specimens were stored in daily renewed artificial saliva. Surface microhardness was assessed using Rockwell hardness test and change in mineral content was evaluated using Energy Dispersive X ray analysis. STATISTICAL ANALYSIS: One way analysis of Variance test and post-hoc Tukey test were conducted for multiple group comparison. RESULTS: There was remarkable remineralisation in Hydroxyapatite treated comparatively to the other three groups. CONCLUSION: All remineralising agents showed improved surface remineralisation. However complete remineralisation did not occur within 7 days. Nanohydroxyapatite showed the highest potential for remineralisation followed by CPP-ACP, Chitosan and Fluoride.
