Consumers are increasingly interested in finding more ecological alternatives to various products. This trend is becoming more common in the market for toothpaste as well. The ROCS Bionica Sensitive® toothpaste is a fluoride-free product containing natural ingredients, which reduces dentine hypersensitivity and offers an ecological alternative in oral health promotion. The purpose of the study ...

Aim: The aim of this study was to measure the radiopacity of seven flowable composite resins (FCRs). Methods: The radiopacity values of Tetric EvoFlow®A3 (Ivoclar Vivadent), PermaFlo®A1 (Ultradent), Filtek Supreme XT®A3 (3M ESPE), wave®A3 (SDI), StarFlow®A2 (Danville Materials), els flow®A3op (Saremco Dental AG) and SYNERGY Nano Formula®A2/B2 (Coltène Whaledent) were determined with reference t...

The hereditary dentine disorders, dentinogenesis imperfecta (DGI) and dentine dysplasia (DD), comprise a group of autosomal dominant genetic conditions characterised by abnormal dentine structure affecting either the primary or both the primary and secondary dentitions. DGI is reported to have an incidence of 1 in 6,000 to 1 in 8,000, whereas that of DD type 1 is 1 in 100,000. Clinically, the t...

Lead concentrations were determined in the exhumed teeth of 28 people who lived in the Cape Town area before the combustion of leaded petrol (i.e. before 1922). The lead content of circumpulpal dentine was analysed by graphite-furnace atomic absorption spectrometry. The mean lead level in the dentine of primary teeth (N = 6) was 109 micrograms/g, while that in secondary teeth (N = 22) was 315 m...

Monkeys were perfused with Karnovsky phosphate-buffered formalin-glutaraldehyde (PBFGTA). Molars were removed and postfixed in PBF-GTA, demineralized in EDTA, freeze-fractured, and critical-point dried. Odontoblast processes were observed in tubules of the predentine, the pulpal inner third of dentine and in the peripheral dentine, but not in the middle third. Peripheral processes showed close ...

Classification: The following classification is based upon the inductive effect of one dental tissue upon another. In normal tooth development, it has been observed that ameloblastic epithelium exerts an influence upon the undifferentiated mesenchymal cell of the dental papilla "inducing" adjacent cells to further differentiate into odontoblasts. The odontoblasts then begin to form dentine. The...

An important consideration in endodontic treatment is the elimination of microorganisms, including fungi, from the complex threedimensional root canal system. Yeasts can be detected in 7-17% of infected root canals. Candida albicans (CA) has a major role in endodontic treatment failure as the most important fungus isolated from the root canal system. C. albicans has been associated with root ca...
