13. Is there difference of Streptococcus mutans count and adherence on amalgam and resin occlusal restorations? A blind clinical study
AIM: To compare the number of colony forming units CFU and agar adherence of S. mutans on amalgam AM and resin composite RC occlusal restorations. Sixty-five healthy patients older than 18 years with high caries risk who had at least one occlusal AM and RC restorations n=130 were selected. METHODS: The restorations were evaluated according to the alpha Ryge

15. Recovering Streptococcus mutans over restorations by the tray technique: a randomized clinical study
AIM: To correlate the tray technique for isolation and counting of Streptococcus mutans over dental restoration with the toothpick technique. METHODS: Forty 18-50-year-old patients of both genders with high cariogenic risk were selected. Inclusion criteria were: occlusal restoration evaluated as alpha, according to the Ryge's criteria (examiner' Cohen-Kappa

16. Microleakage in combined amalgam/composite resin restorations in MOD cavities
AIM: To compare marginal seal at tooth-material and material-material interfaces in the proximal box in combined amalgam/composite resin restorations. METHODS: Mesio-occlusal-distal (MOD) cavities were prepared in 35 premolars and permanent molars with carbide bur. The distal proximal box was restored with amalgam (Permite, SDI) until reaching the height of

17. Caracterização clínica-histológica e estudo de polimorfismos das respostas T-Helper-1 e 2 (Th1/2) nas doenças imunologicamente mediadas com manifestações bucais : líquen plano oral e reação liquenóide oral por amálgama dental / Clinical-histological characterization and study of polymorphisms of T-Helper-1 and 2 (Th1 / 2) responses in immune-mediated diseases with oral manifestations : oral lichen planus and amalgam-associate oral lichenoid reaction
As lesões liquenóides orais (LLO), como líquen plano oral (LPO) e reação liquenóide oral por amálgama dental (RLO-AD), são doenças imunologicamente mediadas (DIM) com características histopatológicas semelhantes, porém com prognósticos distintos. As suas etiopatogenias têm sido relacionadas a polimorfismos gênicos e secreção citocinas de inf
