Adresa za dopisivanje Sérgio Luiz Pinheiro Rua Raul Gasparini, no 525, Bairro Panorama, Residencial Jardim das Palmeiras, Vinhedo – São Paulo Brazil – CEP 13280-000 tel: 55 11 992450090 / 55 19 38864258 [email protected] Sažetak Svrha: Željela se procijeniti moguća inhibicija rasta bakterije S. mutans na karioznom modelu koristeći se stakloionomernim cementom (GIC) pomiješanim s kazein fosfopeptidom/amorfnim kalcijevim fosfatom (CPP/ACP) te lizozimom, laktoferinom i laktoperoksidazom (LLL). Materijali i metode: Odabrano je osamdeset trajnih trećih kutnjaka (molara). Dentin tih zuba ogoljen je i zaglađen. Osim koronalnoga dijela dentina, ostatak zuba hermetički je zabrtvljen, steriliziran i izvrgnut karijesnom utjecaju S. mutans. Karijesne lezije zatvorene su kako slijedi: grupa 1 (n = 20): GIC bez dodataka; grupa 2 (n = 20): GIC + CPP/ACP; grupa 3 ( n= 20): GIC + LLL; grupa 4 (n = 20): GIC + CPP/ACP + LLL. Broj bakterija S. mutans određivao se prije nego što su karijesni zubi zatvoreni (n = 5), nakon 24 sata (n = 5), nakon mjesec dana (n = 5) i nakon šest mjeseci (n = 5). Rezultati su analizirani opisnom statističkom analizom i Kruskal-Wallisovim testom (Student-Newman-Keulsov test). Rezultati: Mjesec dana nakon zatvaranja kombinacija GIC + LLL uzrokovala je značajnu redukciju rasta S. mutans (p < 0,01), no unatoč tomu zabilježen je značajan rast S. mutans šest mjeseci nakon zatvaranja. Uzorci GIC-a, GIC + CPP/ACP i GIC + CPP/ACP + LLL imali su značajnu redukciju S. mutans nakon 24 sata (p < 0,05), ali i porast broja bakterija nakon mjesec dana i šest mjeseci. Zaključak: Dodavanje LLL-a u GIC snažnije antimikrobno djeluje na S. mutans. To rezultira jednomjesečnom kontrolom bakterijskoga biofilma, što na kraju zaustavlja karijesnu leziju.

Comparison the effect of casein phosphopeptide amorphous calcium phosphate and fluoride varnish on dentin hypersensitivity reduction
Introduction: Nowadays, several casein components such as casein phosphopeptide amorphous calcium phosphate (CPP-ACP) are vastly considered as a suitable replacement for fluoride component . The aim of this study was to compare the effect of CPP-ACP paste and fluoride varnish on dentin hypersensitivity reduction. Materials & Methods: In this clinical trial study, thirty adult patients betwee...
متن کاملShear Bond Strength of Composite to Primary Enamel Treated with Casein Phosphopeptide Amorphous Calcium Phosphate Using Total-Etch and Self-Etch Bonding Systems
Background and Aim: By application of casein phosphopeptide amorphous calcium phosphate (CPP-ACP) as a remineralizing agent, it may be feasible to only remove the carious dentin and better preserve the tooth structure. This study aimed to assess the shear bond strength of composite to primary enamel treated with CPP-ACP using total-etch and self-etch bonding systems. Materials and Methods: T...
متن کاملEffectiveness of casein phosphopeptide-amorphous calcium phosphate and lysozyme, lactoferrin, and lactoperoxidase in reducing Streptococcus mutans counts in dentinal caries.
This study compared the capacity of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) to that of a combination of lysozyme, lactoferrin, and lactoperoxidase (LLL) in root canal disinfectant for reducing the Streptococcus mutans counts from dentinal caries. Forty human permanent third molars were selected, and flat dentin surfaces were created. Carious lesions were induced using a micr...

Aim To compare new remineralizing agents calcium sodium phosphosilicate paste and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) paste with that of fluoridated toothpaste in remineralization of early carious lesions using scanning electron microscopy and energy-dispersive X-ray (SEM-EDX) analysis. Materials and methods Sixty sound extracted premolars were collected and placed in ...
متن کاملShear Bond Strength and Remineralisation Effect of a Casein Phosphopeptide-Amorphous Calcium Phosphate-Modified Glass Ionomer Cement on Artificial “Caries-Affected” Dentine
This study investigated the effect of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP)-modified glass ionomer cement (GIC) on shear bond strength (SBS) and remineralisation of artificial "caries-affected" dentine. Human dentine slices were demineralised and allocated to three groups: group 1, conventional GIC; group 2, CPP-ACP-modified GIC; and group 3, resin-modified GIC. The SBS wa...
