Disturbance strongly impacts patterns of community diversity, yet the shape of the diversity-disturbance relationship remains a matter of debate. The topic has been of interest in theoretical ecology for decades as it has practical implications for the understanding of ecosystem services in nature. One of these processes is the remineralization of organic matter by microorganisms in coastal mar...

It is known that the production of acid by oral bacteria dissolves mineral phases on enamel surface, facilitating formation dental caries, with lactic being main cause followed acetic and propionic acids. Fluoride-containing materials play an important role in preventing demineralization remineralization these are widely used dentistry. Although benefits fluoride terms reducing incidence caries...

STATEMENT OF PROBLEM Caries development under overdentures has been a continuing problem and requires the daily use of fluoride to prevent demineralization. PURPOSE The purpose of this in vitro study was to compare the effectiveness of dentifrices containing tricalcium phosphate or calcium phosphosilicate in combination with fluoride to prevent the demineralization of overdenture abutments an...

OBJECTIVES The aim of this study was to evaluate the efficiency of ozone alone and with a re-mineralizing solution following application on initial pit and fissure caries lesions in permanent molars. METHODS Forty children (9-12 years) having non-cavitated fissure caries lesions on bilateral 40 first permanent mandibular molar teeth were participated in the study. Patients were randomly alloc...

OBJECTIVE Tooth bleaching tends to increase enamel roughness and porosity, in addition to reducing surface microhardness. The aim of this in vitro study was to evaluate the effects of bleaching treatments using different hydrogen peroxide (HP) concentrations, with and without light activation on bovine enamel microhardness. MATERIALS AND METHODS The buccal surfaces of sixty bovine incisors we...

As all practitioners are aware, the prevalence and incidence of dental caries keep increasing constantly therefore early diagnosis cessation further progression would greatly help in maintaining sound tooth structure. One earliest signs is a white spot lesion, which mostly missed, only treated when condition worsens. WSL areas demineralized enamel that occur due to prolonged period retained mic...

novamin, a synthetic mineral composed of calcium, sodium, phosphorous and silica releases deposits of crystalline hydroxyl-carbonate apatite (hca) structurally similar to tooth mineral composition. the aim of this investigation was to compare the potential remineralization effect of topical novamin and sodium fluoride gel on caries like lesions in permanent teeth.a total of 60 sound human fresh...

Children are prone to develop dental caries. This is supported by epidemiological data confirming early childhood caries (ECC) as a highly prevalent disease affecting more than every second child worldwide. ECC known result from an imbalance between re- and demineralization where dominates due frequent acid production cariogenic bacteria present in oral biofilms. The application of care formula...
