1. Age estimation by pulp/tooth area ratio in anterior teeth using cone-beam computed tomography: comparison of four teeth
Abstract Objectives Age estimation is one of the most important factors in forensic medicine. Measuring secondary dentin deposition using cone-beam computed tomography images is an easy and noninvasive method. The aim of this study was to evaluate cone-beam computed tomography images as a reliable method to estimate chronological age by pulp/teeth ratio in

2. Efficacy of removal of cariogenic bacteria and carious dentin by ablation using different modes of Er:YAG lasers
The primary objective of this in vitro study was to evaluate the efficiency of removal of cariogenic bacteria and carious dentin by ablation using two lasers: fluorescence-feedback controlled (FFC) Er:YAG laser and different pulses of Er:YAG laser based on variable square pulse technology (VSPt). The secondary objective was to measure the temperature during

4. Cariostatic effect of fluoride-containing restorative materials associated with fluoride gels on root dentin
Secondary caries is still the main cause of restoration replacement, especially on the root surface OBJECTIVE: This in vitro study evaluated the cariostatic effects of fluoride-containing restorative materials associated with fluoride gels, on root dentin. MATERIALS AND METHODS: A randomized complete block design was used to test the effects of the restorati

5. Validity and reliability of methods for the detection of secondary caries around amalgam restorations in primary teeth
Secondary caries has been reported as the main reason for restoration replacement. The aim of this in vitro study was to evaluate the performance of different methods - visual inspection, laser fluorescence (DIAGNOdent), radiography and tactile examination - for secondary caries detection in primary molars restored with amalgam. Fifty-four primary molars wer

6. Chemical, microbiological and mechanical analysis of adhesive system contaning antibacterial monomer and fluoride bonded to dentin / Analise quimica, microbiologica e da resistencia de união a dentina do sistema adesivo contendo monomero antibacteriano e ions fluoreto
The antibacterial monomer 12-methacryloyloxydodecylpyridinium bromide (MDPB) was incorporated with fluoride component in Clearfil Protect Bond adhesive system to help in secondary caries prevention. Thus, the present study conducted three in vitro experiments with the aim to evaluate the fluoride and MDPB effects in cavity disinfection, bonding durability on

7. AvaliaÃÃo in situ da influÃncia da utilizaÃÃo de diferentes sistemas adesivos no desenvolvimento da cÃrie secundÃria em esmalte / In situ evaluation of secondary caries inhibition promoted by self-etch adhesive systems containing antibacterial agents
Contemporary adhesives systems present satisfactory bonding to enamel and dentin. However, replacement of the restorations due to secondary caries formation is still a major problem and of great concern in Dentistry. Thus, this study assessed in situ the effects of adhesive systems containing or not fluoride and/or the antibacterial monomer 12-methacryloylox

8. Efeito do fluor de um sistema adesivo na resistencia de união e no desafio acido em dentina / Effect of fluoride containing adhesive system on microtensile bond strength and acid challenge on dentin
Despite of the advance in adhesive dentistry, it is not possible to achieve an ideal bonding between composite resin and dental substrate. Currently, a variety of adhesive systems have been used. However, any adhesive system is capable to hamper the marginal leakage, degradation, and secondary caries formation at dentin-resin interfaces in long-term. For tha

9. Comportamento dos sistemas adesivos com fluor frente ao desafio cariogenico
The aim of this study was to investigate the behavior of fluoride-free and fluoride-containing adhesive systems subject to dynamic chemical induction of secondary caries, by means of the microtensile bond strength test, establishment of carious lesion depth and the amount of fluoride-ion release from each adhesive system. Eighty extracted bovine incisors wer

10. Avaliação da influência do laser de Er:YAG no selamento de cavidades de cárie radicular induzidas in vitro e restauradas com cimentos de ionômero de vidro / Evaluation of the influence of the Er:YAG laser on the sealing of in vitro induced root caries cavities restored with glass ionomer cements
Failures of root caries restoration such as microinfiltration and secondary caries are mostly due to the difficult to reach the lesions and to the types of substrate. Thus, there is a constant search for new dental materials and caries removal techniques in order to minimize or extinguish these failures. The aim of this study was to induce root caries in vit

11. Efeito de materiais restauradores fluoretados no desenvolvimento de carie secundaria em dentina redicular
In vitro studies have shown that fluoride containing restorative materials can inhibit root dentin secondary caries. However, questions still arise on the potential of some restorative materials, on the extension of the cariostatic effect from the restoration margins and on the in vivo ability of such materials to prevent secondary root caries. This thesis,

12. Avaliação do desenvolvimento in vitro de carie secundaria em esmalte e dentina radicular adjacentes a restauração metalica cimentada : comparação entre cimento de ionometro de vidro modificado por resina e cimento de fosfato de zinco
Secondary caries is reported as the main cause of failure of indirect restorations. MateriaIs with fluoride release have been recommended for patients with high risk of caries but there are no conclusive evidences of their effect on fixed prostheses. This study evaluated the influence of a resin-moditied glass ionomer cement on in vitro caries development in
