The study found that higher concentrations cranberry extract significantly reduced the of bacteria’s metabolic activity and acid production and bacterial/ exopolysaccharide biovolumes, as well as resulted in a less compact architectural structure than that of the control-treated biofilms. Orophenol also had a significant impact, but slightly lower than that of cranberries. Only the highest concentration level of blueberry significantly extract reduced metabolic activity and acidogenicity, but did not significantly affect the biovolume or biofilm architecture. The strawberries had no significant impact on any bacterial activity. No extract killed the bacteria. extract from Continued research goes into fruit extracts for oral health care and bacteria management.

5 News 2/19 Study links dental fl ossing to higher levels of toxic chemicals in body by Dental Tribune International an are NEWTON, Mass., U.S.: Per- and polyfl uoroalkyl substances (PFASs) important group of chemicals with wide applications, including dental fl oss, because of their ability to resist both water and lipids. A recent study, conducted by the Silent Spring Institute, has found that fl ossing with a certain brand contributes to elevated levels of toxic PFAS chemicals, which have been linked to various health problems, in the body. The researchers measured 11 PFAS chemicals in blood samples taken from 178 middle- aged women enrolled in the Public Health Institute’s Child Health and Development Studies, a multigenerational study of the impact of environmental chemicals and other factors on disease. To understand how the participants’ behavior infl uenced Ad Researchers have found that certain dental ﬂoss brands expose users to toxic chemicals. (Photograph: LightField Studios/ Shutterstock) based on our fi ndings, consumers can choose fl osses that don’t contain PFAS.” The study, titled “Serum concentrations of PFASs and exposure-related behaviors in African American and non- Hispanic white women,” was published online in the Journal of and Environmental Epidemiology on Jan. 8, 2019. Exposure Science to PFAS, their exposure the researchers then compared the blood measurements with results from interviews in which they asked the women about nine behaviors that could lead to higher exposures. The study found that women who fl ossed with a major brand tended to have higher levels of a type of PFAS called perfl uorohexanesulfonic acid in their body compared with those who did not. To further understand the connection, the researchers tested 18 dental fl osses the presence of for fl uorine, which is a marker of PFAS. All three products of the major brand tested positive for fl uorine. In addition, one store brand fl oss describing itself as a “single-strand Tefl on fi ber” tested positive for fl uorine. The reason scientists are concerned about widespread exposure to PFAS in the population is that the chemicals have been linked to negative health effects, including kidney and testicular thyroid disease, high cancer, cholesterol, low birth weight, decreased fertility and effects on the immune system. “This is the fi rst study to show that using dental fl oss containing PFAS is associated with a higher these body burden of toxic chemicals,” said lead author Katie Boronow, a staff scientist at the institute. “The good news is,
7 Clinical 2/19 Bringing anterior direct composite restorations to life with histologic layering protocols in Discussion Understanding the patient’s requirements aesthetic cases is of utmost importance. Photography and documentation of aesthetic work helps in planning and execution. Having a set protocol with regards to the clinical work flow, makes these cases more predictable. Using a wax up makes it easier to control the palatal anatomy and of emergence the restoration.

Histologic layering technique adds life to anterior composite restoration. Picture Dr.Priya Titus Singh by Dr. Priya Titus Singh structure, Composite resin is a material that is able to mimic natural tooth its optical properties and aesthetics. Often due to trauma or caries, the anterior teeth get harmed, thus damaging a patient’s smile. In a price sensitive economy, it is often due to budget constraints that a patient would choose direct the anterior teeth rather than going for the more aesthetic, more hassle-free indirect restorations. In such situations, it is up to the composite resin layering abilities of the operating dentist, to restore not only the teeth, but also the smile and self confidence of the patient. restorations in In the natural tooth, we have layers of dentin and enamel, each of which have variations in chromaticity and translucency. For example the dentin that is closest to the pulp and that is near to the dentino enamel junction (DEJ) has different chromas. Similarly the enamel near the DEJ is darker compared to the outermost layer of enamel. The tooth is darkest at its core and starts becoming lighter as we move outwards towards enamel. Considering this natural tooth as a histological guide, we can replace lost dentin structure using opaque dentin shades [with different range of chromaticity] of composite resin. translucent Similarly we can replace lost enamel structure using the more chromatic and achromatic enamel shades. Material manufacturers also make materials with a wide range of hue, value and chroma as well as opacity and translucency. Because of the difference in the refractive indices of the composite material as compared to that of natural dentin and enamel, we have to layer the composite shades in a definite and controlled thickness in order to get the optimum results. In the following case, two mal-aligned, fractured, non-vital central treated endodontically, bleached and restored using direct composite restorations. incisors were Case history 22 yr old Male walked into our dental office saying that he had a fall many years ago and his front teeth were broken. There was no associated pain or symptoms and the problem was purely aesthetic. He was only seeking treatment because he needed to get married soon. He was low on confidence while smiling and required a solution within 4 weeks. On examination The two maxillary central incisors were fractured and non- vital with noticeable darkening of shade [ Fig 1,2 ]. They were mal-aligned buccolingually and there was a midline diastema as well . There was no tenderness on percussion. There were peri- apical lesions associated with both incisors in the radiograph. Treatment Non-surgical the endodontic treatment was done in the 1st week. After symptoms resolved completely we were ready to restore form, function and aesthetics. Non-vital in- office bleaching was done. Pola office bleach was used for the same, 3 cycles of 8 minutes each. It appeared that the shade had corrected completely after bleaching but we waited for it to stabilize. Two weeks later, the shade [ Fig 3 ] stabilized and the teeth were ready for bonding. We observed that the central incisors were still darker than the neighbouring teeth. Direct composite veneers were planned with the help of a lab made wax up [ Fig 4 ] and a putty index. Bevels were placed and most of the preparation was in enamel. After the total etch protocol, 5th generation bonding agent was used. 3M Z350XT shades were used for the build up. A2 Enamel shade was used for the palatal shell [ Fig 6 ] and the proximal walls [ Fig 11 ]. Desaturation was achieved layering a deeper darker by dentin [ A3 Dentin – Fig 12 ] inside and a lighter dentin [ A2 Dentin – Fig 13 ] shade over it in the shape of three mamelons. Incisal Halo was achieved by layering an Achromatic Enamel [clear translucent] shade around the mamelons [ Fig 14 ] and the A2 dentin shade on the incisal edge [ Fig 11 ]. Final layer of A2 Enamel shade was used covering the restoration in 0.5mm thickness so as to avoid too much translucency [ Fig 15 ]. Finishing and polishing were done using the 3M Soflex discs and spirals [ Fig 17 ] as recommended by the manufacturer. We have previously discussed the finishing and polishing protocols of this case in detail in an earlier article [click here for link] Post-op instructions included regular follow ups to see if the peri-apical region was healing properly. Patient has been informed that composite resin is unable to bear shearing forces, the restoration may debond. And that he needs to come back for polishing every 6 months for routine maintenance.
