25. Influence of biofilm formation on the mechanical properties of enamel after treatment with CPP-ACP crème
Abstract: The study aimed to investigate the effects of bacterial biofilms on changes in the surface microhardness of enamel treated with casein phosphopeptide—amorphous calcium phosphate (CPP-ACP) with and without fluoride. Human enamel blocks with incipient caries-like lesions were divided into four groups of 13: G1: Saliva (Control); G2: fluoride dentif

26. Clinical performance of fluorescence-based methods for detection of occlusal caries lesions in primary teeth
Abstract We aimed to investigate the performance of fluorescence-based methods (FBMs), compared to visual inspection after histological validation, in detecting and assessing the activity status of occlusal carious lesions in primary teeth. One examiner evaluated 50 primary molars close to exfoliation in 24 children. Teeth were assessed using quantitative li

27. One year Survival Rate of Ketac Molar versus Vitro Molar for Occlusoproximal ART Restorations: a RCT
Abstract Good survival rates for single-surface Atraumatic Restorative Treatment (ART) restorations have been reported, while multi-surface ART restorations have not shown similar results. The aim of this study was to evaluate the survival rate of occluso-proximal ART restorations using two different filling materials: Ketac Molar EasyMix (3M ESPE) and Vitro

28. Impact of inhalation therapy on the incidence of carious lesions in patients with asthma and COPD
Abstract Objective: The aim of this study was to investigate the incidence of carious lesions, the amount of salivary flow rate and pH value in patients with asthma and chronic obstructive pulmonary diseases (COPD), using inhalation therapy. The obtained results were compared with the results of adult healthy subjects, forming a control group. Material and

29. A randomized clinical trial on the sealing of occlusal carious lesions: 3–4-year results
Abstract This randomized clinical trial aimed to assess the efficacy of sealing occlusal carious lesions in permanent teeth. The sample consisted of 54 occlusal carious lesions in permanent molars and premolars of 49 patients aged 8–43 years (median: 19 years). The inclusion criteria comprised the presence of a cavity with no access allowing biofilm contro

30. The anti-caries activity and toxicity of an experimental propolis-containing varnish
Abstract We investigated the anti-caries effects of an experimental propolis varnish in vivo, and further tested its toxicity against fibroblasts. Fifty-six SPF female Wistar rats were infected with Streptococcus mutans UA159 (SM) and allocated into four groups (n = 14/group): G1, propolis varnish (15%/PV); G2, chitosan varnish (CV/vehicle); G3, gold standar

31. Survival of sealants in molars affected by molar-incisor hypomineralization: 18-month follow-up
Abstract The objective of this study was to evaluate the clinical survival of sealants applied in first permanent molars (FPMs) affected by molar-incisor hypomineralization (MIH), at 18 months of follow-up. Forty-one first permanent molars were selected from 21 children, 6–8 years of age. MIH was classified by one calibrated examiner (kappa = 0.80) accordi

32. Role of Candida species from HIV infected children in enamel caries lesions: an in vitro study
Abstract Objectives This study analyzed the capacity of Candida spp. from dental biofilm of HIV infected (HIV+) children to demineralize primary molar enamel in vitro by Transversal Microhardness (TMH), Polarized Light Microscopy (PLM) and the quantity of calcium ions (Ca2+) released from the enamel. Material and Methods Candida spp. samples were isolated

33. Factors for determining dental anxiety in preschool children with severe dental caries
Abstract The aim of this study was to assess the clinical and socioeconomic indicators associated with dental anxiety in preschool children with severe dental caries. A total of 100 children between 3 and 5 years of age were selected during a dental screening procedure. The selection criteria were having at least one tooth with dental caries and a visible pu

34. Antimicrobial activity of ozone and NaF-chlorhexidine on early childhood caries
Abstract An early childhood carie (ECC) is an extremely destructive form of tooth decay. The aim of this study was to investigate the action of ozone (O3), and the association of sodium fluoride (NaF) with chlorhexidine (CHX) on bacteria related to ECC. Overnight culture of the bacteria was performed. On exponential phase the suspension was adjusted (101-108

35. Incidence of dental caries in primary dentition and risk factors: a longitudinal study
Abstract The objectives of this prospective, longitudinal, population-based study were to estimate the incidence of dental caries in the primary dentition, identify risk factors and determine the proportion of children receiving dental treatment, through a two-year follow up. The first dental exam was conducted with 381 children aged one to five years, at he

36. Parental influence on children’s answers to an oral-health-related quality of life questionnaire
Abstract The aim of the study was to evaluate parental influence on children’s answers to an oral health-related quality of life (OHRQoL) questionnaire. A cross-sectional study was conducted with a non-probabilistic sample of 84 pairs of 5-year-olds and parents/guardians. The participants were selected from a primary family healthcare center in Campina Gra
