Abstract
OBJECTIVE This study examined the effects of MTA and Biodentine on the clinical and radiographic success rates of pulpotomies performed on primary teeth with carious pulp exposures. MATERIALS AND METHODS This study was conducted with 44 mandibular primary molars requiring vital pulpotomy. Carious dentin surrounding the exposure site was used as the inclusion criteria for all teeth, which were randomly divided into two groups according to pulpotomy material [MTA group (n = 24), Biodentine group (n = 20)]. Treatment was followed up clinically and radiologically for 24 months. Pulp canal obliteration was not regarded as a failure. RESULTS Clinical and radiographic success rates at the end of 24 months were 100% for the MTA group and 89.4% for the Biodentine group. Success rates did not vary significantly between the groups (p = 0.646). Pulp canal obliteration was observed in two teeth (8.3%) in the MTA group at 6 months, but the teeth were found to be stabilized by 24 months. CONCLUSION The long-term clinical and radiographic success rates obtained in this study indicate that both MTA and Biodentine are appropriate options for pulpotomy treatment of primary teeth with carious exposure in patients whose teeth should be retained for long periods of time. CLINICAL RELEVANCE The etiology of exposure determines pulpal response, making it crucial to distinguish between mechanical and carious exposures. The carious exposure is presumed to be accompanied by severe inflammation, which makes the prognosis of treatment unpredictable. Biomaterials can be used especially in cases with carious pulp exposures.

Abstract
OBJECTIVES Bioactive glasses which degrade in aqueous solutions may release bioactive ions such as fluoride (F-) and support fluoride bioavailability in saliva. We investigated how these effects would be apparent in an in vivo experimental trial after toothbrushing in comparison with sodium fluoride and amine fluoride. MATERIAL AND METHODS In this single-center, randomized, parallel in vivo trial with a three strata block design, where healthy subjects were randomly assigned into three groups. Each group brushed their teeth either with fluoridated bioactive glass containing dentifrice, with a sodium fluoride (NaF) containing dentifrice or with amine fluoride (AmF) containing toothpaste. Saliva was collected time intervals before, immediately after, 30, 60 and 120 min after toothbrushing. Fluoride concentration was determined in supernatant saliva and salivary sediment using a fluoride ion selective electrode. The data were evaluated statistically using non-parametric tests. RESULTS The increase of bioactive fluoride in supernatant saliva was higher after application of NaF or AmF compared to fluoridated bioactive glass. In salivary sediment bioavailability of fluoride lasted longer after application of fluoridated bioactive glass. CONCLUSIONS Toothbrushing with the fluoride containing bioactive glass dentifrices had positive effects on the fluoride bioavailability within two hours. Fluoride containing bioactive glass represent a new area for investigation in caries prophylaxis. The bioactive potential impact on the tooth remineralization should be examined further.
