Comparative Evaluation of the Depth of Penetration of different Types of Desensitizing Agents into the Dentinal Tubules: An in vivo Study

ABSTRACT Aim Aim of the study is to evaluate the depth of penetration of different types of desensitizing agents into the dentinal tubules in vivo. Materials and methods Twenty patients requiring tooth extraction for orthodontic purpose were selected. In all four premolars of the selected patients, small class V cavities were prepared on the buccal surface having depth of 0.5 mm. They were divided into four groups and treated with four different types of desensitizing agents (5% NaF solution, Gluma desensitizer, FluorProtector, and SuperSeal) for required time and then they were extracted. They were longitudinally sectioned and each section was studied by scanning electron microscope. Results The mean depth of penetration of SuperSeal and Gluma was significantly higher than that of other agents (sodium fluoride and FluorProtector) (p<0.05). No significant difference was found between SuperSeal and Gluma (p>0.05). Conclusion The depth of penetration of resinous desensitizing agent (Gluma) is maximum followed by potassium oxalate solution (SuperSeal) and fluoride varnish (FluorProtector). Clinical significance Deeper the penetration of desensitizing agents into the dentinal tubules, longer the efficacy. How to cite this article Mitra A, Adhikari C.

Objective: The purpose of this in vivo study was to compare and evaluate the clinical efficacy of two gingival retraction systems; Ultrapak and Traxodent, on the basis of the amount of gingival retraction achieved in vertical and horizontal direction and their hemorrhage control. Methods: A total of 60 subjects were selected requiring fixed prosthesis. The two gingival retraction systems were used on the prepared abutments randomly. The vertical gingival retraction was measured before and after retraction using flexible measuring strip with 0.5 mm grading. The horizontal retraction was measured on the casts poured in polysilicone impressions made before the retraction and after retraction. Results: Statistically significant difference (p<0.05) was found between the amount of the retraction (vertical and horizontal) achieved by Ultrapak as compared to Traxodent. However, in achieving hemostasis Traxodent showed better efficiency than Ultrapak (p<0.05). Conclusion: The mean retraction width and depth achieved with retraction cord (Ultrapak) was significantly greater when compared with retraction paste. Although retraction paste (Traxodent) showed bleeding index significantly less when compared to that of retraction cord (Ultrapak).

ABSTRACT This study demonstrated the capacity of bacteriocin-producing lactic acid bacteria (LAB) to reduce intestinal colonization by vancomycin-resistant enterococci (VRE) in a mouse model. Lactococcus lactis MM19 and Pediococcus acidilactici MM33 are bacteriocin producers isolated from human feces. The bacteriocin secreted by P. acidilactici is identical to pediocin PA-1/AcH, while PCR analysis demonstrated that L. lactis harbors the nisin Z gene. LAB were acid and bile tolerant when assayed under simulated gastrointestinal conditions. A well diffusion assay using supernatants from LAB demonstrated strong activity against a clinical isolate of VRE. A first in vivo study was done using C57BL/6 mice that received daily intragastric doses of L. lactis MM19, P. acidilactici MM33, P. acidilactici MM33A (a pediocin mutant that had lost its ability to produce pediocin), or phosphate-buffered saline (PBS) for 18 days. This study showed that L. lactis and P. acidilactici MM33A increased the concentrations of total LAB and anaerobes while P. acidilactici MM33 decreased the Enterobacteriaceae populations. A second in vivo study was done using VRE-colonized mice that received the same inocula as those in the previous study for 16 days. In L. lactis-fed mice, fecal VRE levels 1.73 and 2.50 log10 CFU/g lower than those in the PBS group were observed at 1 and 3 days postinfection. In the P. acidilactici MM33-fed mice, no reduction was observed at 1 day postinfection but a reduction of 1.85 log10 CFU/g was measured at 3 days postinfection. Levels of VRE in both groups of mice treated with bacteriocin-producing LAB were undetectable at 6 days postinfection. No significant difference in mice fed the pediocin-negative strain compared to the control group was observed. This is the first demonstration that human L. lactis and P. acidilactici nisin- and pediocin-producing strains can reduce VRE intestinal colonization.
