    Caries experience in relation to oral hygiene, salivary cariogenic microflora, buffer capacity and secretion rate in 6-year olds and 12 year olds in Riga
    (2008) Gudkina, Jekaterina; Brinkmane, Anda; Rīga Stradiņš University
    OBJECTIVE: The aim was to assess possible relationship between oral hygiene, salivary cariogenic microflora, buffer capacity, secretion rate and caries experience in 6 year olds and 12 year olds in Riga, and to evaluate these variables in relation to caries risk. MATERIALS AND METHODS: 50 children aged 6 and 71 children aged 12 were examined clinically and by bitewing X-ray for caries diagnosis. Green-Vermillion oral hygiene index, stimulated salivary flow rate and buffer capacity were estimated (CRT-buffer; Ivoclar, Vivadent, Liechtenstein). Salivary mutans streptococci (MS) and lactobacilli (LB) (CRT-bacteria; Vivadent) were determined only for children with dmft/DMFT>4: 60% at age of 6, 54,9% at age of 12. All data were statistically analyzed using frequency tables, Pearson chi2test and ANOVA analysis. RESULTS: Mean DMFT was 0.12 in 6 year olds, and 4.6 in 12 year olds. Mean Green-Vermillion index was 0.75 in 6 year olds and 0.99 in 12 year olds. Caries experience and Green-Vermillion index were associated only in 6 year olds (p=0.024). Salivary MS was associated with Green-Vermillion index only in 12 year olds (p=0.086). Salivary MS and caries experience were associated only in 12 year olds (p=0.010). Salivary LB was associated with stimulated saliva's secretion rate only in 12 year olds (p=0.027). Salivary cariogenic microflora level and buffer capacity were associated in 6 year olds (p for MS=0.010; p for LB=0.052). Same association was observed only between salivary MS and buffer capacity in 12 year olds (p=0.081). Stimulated saliva's secretion rate and buffer capacity were associated only in 12 year olds (p=0.004). CONCLUSIONS: Information of caries risk factors should be used to work effectively on caries reduction in 6 year olds and 12 year olds in Riga.

    Caries Increment and Oral Hygiene Changes in 6-and 12-Year-Old Children in Riga, Latvia : A 3-Year Follow-Up Report Using ICDAS II and RADKE Criteria
    (2019) Gudkina, Jekaterina; Amaechi, Bennett T.; Abrams, Stephen H.; Brinkmane, Anda; Jelisejeva, Ieva; Department of Conservative Dentistry and Oral Health
    Objectives: The purpose of this study was to investigate the caries increment and oral hygiene changes over a 3-year period and also compare the sensitivity and specificity of Radke's caries assessment method to ICDAS II among 6-and 12-year-old children in Riga, Latvia. Materials and Methods: Thirty-eight 6 and thirty-nine 12-year-old children were examined visually and with bitewing (BW) radiographs for dental caries at baseline and after a 3-year period. Decayed, missing, and filled surfaces (dmfs/DMFS) in all teeth were scored by one calibrated examiner using the Radke's caries scoring criteria. Oral hygiene level was determined using Green-Vermillion index (G-V ind.) at baseline and after 3 years. ICDAS II was used to assess all children only at the 3rd-year time point. The parents of the 6-and 12-year-old children responded to a questionnaire on oral hygiene at baseline and at the 3-year mark. Statistical Analysis: The data were analyzed using t-test, Chi-square test, Wilcoxon test (α= 0.05), and sensitivity and specificity tests. Results: The mean (SD) values of G-V ind. and caries experience at baseline/3-year period in 6-versus 12-year-old children were as follows. G-V ind.: 1.14(0.80)/1.48(0.89) [p = 0.4768] versus 0.99(0.45)/1.45(1.22) [p = 0.0337]. DMFS: 0.72(1.02)/3.13(3.13) [p = 0.0000] versus 6.79(5.14)/14.79(9.86)[p = 0.0000]; dmfs: 11.26(8.71)/7.74 (4.86) [p = 0.0780] versus 3.57 (2.03)/1.5(0.71)[p = 0.3173].The sensitivity and specificity of Radke to ICDAS II of caries-affected surfaces was: in proximal surfaces-0.57 and 0.98, on occlusal surfaces-0.83 and 0.98, on buccal/lingual surfaces-0.43 and 0.99. Conclusions: The result of the present study suggests that the increased caries experience over a 3-year period among the 6-and 12-year-old children in Riga may be due to the concurrent decreased level of oral hygiene, suggesting that ICDAS II instead of Radke's criteria should be used to detect and monitor dental caries.

    Factors influencing the caries experience of 6 and 12 year old children in Riga, Latvia
    (2016) Gudkina, Jekaterina; Brinkmane, Anda; Abrams, Stephen H.; Amaechi, Bennett T.; Rīga Stradiņš University
    AIM: Authors assessed the influence of drinking tea with sugar, level of cariogenic microflora and use of fluoride toothpaste and tablets on caries experience of 6 and 12 year old children in Riga, Latvia. METHODS: 141 six and 164 twelve year old children were examined clinically and with bitewing radiographs to determine their dmft/DMFT and dmfs/DMFS. Children or their parents responded to questionnaire on number teaspoons of sugar (TS) used per cup of tea, number of cups of tea consumed daily, using fluoride or non-fluoride toothpaste (TP), frequency of toothbrushing, using fluoride tablets or not (ft). Salivary mutans streptococci (MS) and lactobacilli (LB) levels were measured in children with dmft/DMFT>4.0 for age of 6 (73% (n=103)), and for age of 12 (54% (n=88)). Impact of variables in caries status was determined using frequency tables and ANOVA, while proportion differences were tested using chi-square test. RESULTS: In 6 year olds, statistically significant associations were observed between the salivary microflora (MS, LB) and dt/DT (p=0.032; dt=3.71, DT=0.42), use of F-toothpaste (p=0.020), and TS (p<0.001). In 12 year olds, statistically significant (p<0.01) associations were observed between salivary microflora and dt/DT, ds/DS and dmft/DMFT. In both age groups, significant (p<0.001) association was demonstrated between dmfs/DMFS and salivary microflora, F-toothpaste and TS. CONCLUSIONS: The present study indicated that the caries development in Latvian children was associated with consumption of sugary tea and use of non-fluoride toothpaste.
