In the era of evidence based dentistry, a well-documented consolidated data about improvements in dentistry is a necessity. Concentrated growth factor (CGF) is an emerging trend in periodontology and now in implant dentistry. Various studies have been published in the literature evaluating the effect of CGF on implant osseointegration, implant stability, survival rate, sinus augmentation, and peri-implant defects. However, no systematic review has yet been documented. The present systematic review, being first of its kind, aimed to evaluate the potential outcomes of employing CGF in implant treatment. A literature search was carried out in PubMed and Google scholar for articles published between 2001 and 2019, with various keywords such as “CGF,” “dental implant,” “bone regeneration,” “CGF,” and “osseointegration.” The screening of studies was done according to PRISMA guidelines. A total of eleven studies were included in this review. Majority of the included studies pointed toward the beneficial effects of CGF in implant treatment. CGF was seen to promote osseointegration and enhance bone regeneration. Although more clinical studies are required to validate the potential merits of CGF in the long run, the preliminary results seem promising.

Life of living or non-living being depends on water; in short, water is life. But these days, with the growing industrialization, it is spoiling a lot. Wastewater contains contaminants like acids, bases, toxic organic and inorganic dissolved solids, and colors. Out of them, the most undesirable are colors caused mainly by dyes. Color and other compounds present in water are always not desirable for domestic or industrial needs. The wastes of dyes are predominant amongst all the complex industrial wastewater. This water is dark in color and highly toxic, blocking the sunlight and affecting the ecosystem. Among all the dyes, azo dyes contribute to commercial dyes used widely in textile, plastic, leather, and paper industries as additives. The removal and degradation of azo dyes in aquatic environment is important because they are highly toxic to aquatic organisms. For every industry, clean technology has become an important concern. In this chapter, the authors discuss about existing processes as well as promising new technologies for textile wastewater decolorisation.

Background: Oral diseases are major public health problems due to their high prevalence and significant social impact. Oral hygiene practices play a critical role in their prevention and control. This study was carried out to evaluate oral hygiene practices and oral status among adolescents in Mangalore taluk, taking into account differences based on location and type of school.Methods: A descriptive cross-sectional study was carried out among 1340 students enrolled in public and private high schools in urban and rural areas of Mangalore taluk. The study sample was equally distributed among urban and rural areas, and among public and private schools. Proforma was prepared to record demographic data, oral hygiene practices, dental caries and periodontal disease. Data were analyzed using Chi-squared test and t-test, with p<0.05 considered statistically significant.Results: Majority of the students used toothbrush and toothpaste to clean their teeth. Horizontal tooth brushing motion and once/twice daily tooth brushing frequency was reported by the highest number of students. Good oral hygiene was found among 55.2% participants. Female participants, urban children and those attending private schools presented with better oral hygiene. Prevalence of dental caries was 59.2%. Prevalence of gingivitis was 83.2%, with higher prevalence among females and rural participants. Poor oral hygiene was found to be associated with gingivitis (r=0.59).Conclusions: Although majority of the participants reported use of requisite oral hygiene aids and regular tooth brushing habits, the high prevalence of oral disease among them can be attributed to poor oral hygiene.
