fa Baseline Dental Plaque Activity, Mutans Streptococci Culture, and Future Caries Experience in Children کودکان Pediatric Dentistry پژوهشي Research <p> <strong>Purpose:</strong> </p><p> The purpose of this study was to evaluate a chairside caries risk assessment protocol utilizing a caries prediction instrument, adenosine triphosphate (ATP) activity in dental plaque, mutans streptococci (MS) culture, and routine dental examination in five- to 10-year-old children at two regional Australian schools with high caries experience. </p><p> <strong>Methods:</strong></p><p>  Clinical indicators for future caries were assessed at baseline examination using a standardized prediction instrument. Plaque ATP activity was measured directly in relative light units (RLU) using a bioluminescence meter, and MS culture data were recorded. Each child's dentition was examined clinically and radiographically, and caries experience was recorded using enamel white spot lesions and decayed, missing, and filled surfaces for primary and permanent teeth indices. Univariate one-way analysis of variance between selected clinical indicators, ATP activity, MS count at baseline, and future new caries activity was performed, and a generalized linear model for prediction of new caries activity at 24 months was constructed. </p><p> <strong>Results:</strong></p><p>  Future new caries activity was significantly associated with the presence of visible cavitations, reduced saliva flow, and orthodontic appliances at baseline (R2=0.2, P<.001). </p><p> <strong>Conclusion:</strong></p><p>  Baseline plaque adenosine triphosphate activity and mutans streptococci counts were not significantly associated with caries activity at 24 months. </p><hr><p></p><p> <strong>Source: </strong>Journal of American Academy of ‍ Pediatric Dentistry</p><p><a href="http://www.ingentaconnect.com/content/aapd/pd/2013/00000035/00000007/art00011" target="_blank"><font color="#0000ff"> Full Text</font></a></p> DENTAL CARIES; DENTAL CARIES ACTIVITY TESTS; DENTAL CARIES SUSCEPTIBILITY 0 0 http://idai.ir/browse.php?a_code=A-10-32-2604&slc_lang=fa&sid=1 Kerrod B.
