RESUMO
OBJECTIVE: To compare the duration (hours until HCO3- ≥ 15 mmol/L) of diabetic ketoacidosis (DKA) episodes that are the first manifestation of new type 1 diabetes (NT1D) and those that are a complication in patients with previously diagnosed type 1 diabetes (PT1D). METHODS: A multicenter retrospective cohort study was designed. The duration of DKA was measured from the start of the treatment. The primary outcome was the comparison of the time needed in each group to reach HCO3- ≥ 15 mmol/L. The secondary outcomes were the comparison of the time to reach pH ≥ 7.3 and length of hospital stay in each group. Data were analyzed with a bivariate analysis of the variables vs primary outcome. Then, a regression model was analyzed. Results There were 305 episodes included (NT1D: 115, PT1D: 190). DKA in the NT1D group lasted longer (NT1D 20 (16-19) vs PT1D 12 (8-16), hours, P < .01) with a significant difference in each level of DKA severity. This group also took longer to reach pH ≥ 7.3 (NT1D 16 (12-22) vs PT1D 9 (6-12), hours, P < .01) and had a longer hospital stay (NT1D 9 (6-12) vs PT1D 7 (4-10), hours, P < .01). CONCLUSION: The duration of DKA is longer in patients with NT1D regardless of characteristics like DKA severity, duration of symptoms, and type of treatments received.

OBJECTIVES: An in vitro study was performed to detect occlusal caries lesions of extracted permanent human molars by electrical conductance measurement with the Ortek ECD™ electronic device, and each tooth was sectioned and biopsied to validate and evaluate results. METHODS: Thirty-nine permanent molars were extracted. Thirteen were freshly erupted and had little opportunity to develop lesions. Twenty-six were in the mouth longer and likely to be carious. After extraction and storage in a mild disinfectant, each tooth was thoroughly rinsed with distilled water and positioned upright to enable its electrical conductance measurement. Electrical conductance was measured in pits and fissures of carious and non-carious permanent molars with an Ortek ECD. Crowns were sectioned horizontally producing 630 µm thick slices and examined individually for demineralization by light microscopy and photography. Tooth biopsy was analyzed to ascertain the degree of tooth demineralization. RESULTS: Visual examination by light microscopy and photography of the sections of non-carious and carious teeth were analyzed. Noncarious teeth showed no mineral loss and showed an electrical conductance score of 0.0 µA. In carious teeth, this score ranged from 0.3 to 3.0. A significant (p < 0.001) correlation coefficient (r) of 0.914 was obtained. Electrical conductance versus biopsy resulted in high values for sensitivity (100%) and specificity (93%). It showed a positive predictive value (PPV) of 96% and a negative predictive value (NPV) of 100% for electrical conductance versus biopsy. CONCLUSIONS: Subject to in vivo clinical support, the Ortek ECD is likely to prove to be the best method for detection and evaluation of early occlusal caries.

In Cuba, despite a high sero-prevalence of bluetongue virus (BTV), circulating serotypes remain unknown. The aim of this study was to identify circulating BTV serotypes in farms throughout the western region of Cuba. Blood samples were collected from 200 young cattle and sheep between May and July 2022 for virological analyses (PCR, viral isolation and virus neutralization) and genome sequencing. The results confirmed viral circulation, with viro-prevalence of 25% for BTV. The virus was isolated from 18 blood samples and twelve BTV serotypes were identified by sequencing RT-PCR products targeting the segment 2 of the BTV genome (BTV-1, 2, 3, 6, 10, 12, 13, 17, 18, 19, 22 and 24). Finally, the full genome sequences of 17 Cuban BTV isolates were recovered using a Sequence Independent Single Primer Amplification (SISPA) approach combined to MinION Oxford Nanopore sequencing technology. All together, these results highlight the co-circulation of a wide diversity of BTV serotypes in a quite restricted area and emphasize the need for entomological and livestock surveillance, particularly in light of recent changes in the global distribution and nature of BTV infections.

The aim of this study was to describe the initial oral microbiota and how delivery mode and feeding practices impact its diversity in 0-2-month-old infants. This was a cross-sectional study that consisted of one collection of saliva samples from 0-2-month infants at baseline. Ten pairs of mothers and infants were selected. Medical health history, pregnancy, birth, feeding practices (breastfeeding or milk formula), and infant health status was obtained. Pooled microbial samples were obtained from the oral surfaces using a sterile cotton swab. Infants did not receive any breast milk before sampling. After collection, each swab was analyzed through microbiological culture-based procedures, using selective mediums. Cultures were analyzed for the presence of Streptococci, Lactobacillus, Staphylococcus, Enterobacterium , and Candida albicans . Twenty percent of the samples were serially diluted (10-2) to assess the number of bacteria expressed as CFU. Bacillota was the leading phylogenetic group in the infant's pooled microbial sample. The most prevalent genera were Streptococcus, Lactobacillus , and Staphylococcus . Two participants had a positive growth of Candida albicans . The association between genus group, type of delivery, and feeding practices was not statistically significant (p > 0.05). Lactobacillus genus was frequently present in the cesarean delivery group but with slightly higher counts in a vaginal delivery study subject. Exclusively breastfed infants showed presence of Streptococcus, Lactobacillus, Staphylococcus . The oral microbiome in infants (0-2 month-old) is highly heterogeneous and dynamic. Microbiota composition seems to be impacted by mode of delivery, with slight differences among groups. Breastmilk appears as an essential factor in maintaining the oral microbiome's stability and diversity.

The aim of this multicenter study was to explore the early-life sugar consumption and dietary practices in Latin America as well as to investigate the association between breastfeeding duration and the age at which foods and beverages with added sugars are introduced. A cross-sectional study was conducted with 805 1- to 3-year-old children from 10 Latin American countries, as a complementary study to the Research Observatory for Dental Caries of the Latin American Region (OICAL). A Food Frequency Questionnaire previously tested in different countries was applied to children's mothers and data on breastfeeding and age at introduction of sugary foods and beverages was collected. Statistical analysis included the Kruskal-Wallis test and Poisson regression with robust variance, with the calculation of crude and adjusted mean ratios (MR) and 95% of confidence intervals (CI). The average age at introduction of sugary foods and beverages was 10.1 months (95%CI 9.7-10.4) and 9.6 (95%CI 9.2-9.9) months, respectively, with a significant variation between countries (p < 0.001). The average daily frequency of sugary foods-beverages was 3.3 times per day (95%CI 3.1-3.5) and varied significantly between countries (p = 0.004). Breastfeeding duration of over six months was associated with an increase in the age of introduction of sweet drinks (16%; MR 1.16; 95%CI 1.05-1.28) and foods (21%; MR 1.21; 95%CI 1.10-1.33). In conclusion, most children from vulnerable settings in Latin America start consuming sugary products in the first year of life and a high frequency of consumption was reported through early childhood. Additionally, breastfeeding contributes to a delay in the introduction of sugary products.

Policy evaluation and guidance on fluoride use and sugar consumption in Latin American and Caribbean countries (LACC) may provide a scientific evidence basis for policymakers, dental professionals, civil society organizations and individuals committed to improving public oral health. A cross-sectional study was conducted to evaluate the extent of implementation of policies/guidelines on fluoride use, and sugar consumption in LACC. The study had two stages. First a questionnaire covering four major areas was developed: fluoridation of public water supplies; salt fluoridation; fluoride dentifrices, and sugar consumption. Then, the questionnaire was applied to collect data among representative participants in public oral health from LACC. Ninety-six participants from 18 LACC answered the questionnaire. One-hundred seventy documents were attached, and 285 links of websites were provided by the respondents. Implementation of policies and guidelines on water and table salt fluoridation and processed and ultra-processed food consumption were found in most countries, with some issues in the consensus and coverage. Thus, differences were identified in the extent of implementation of public oral health strategies on sugar consumption and fluoridation among the countries. There is no consensus on the policies in LACC to reduce sugar consumption and for the use of fluoride. A few policies and guidelines were applied in isolated countries, with a variety of strategies and standards. For future actions, it will be important to encourage the development of strategies and public policies within countries, and to evaluate the effectiveness of existing policies in reducing dental caries and in improving oral health in LACC.

This research aims to provide updated information on caries experience and associated risk factors in children 6-12 years old. A cross-sectional and descriptive study design was carried out with a non-probabilistic, convenient sample of 209 children male and female. Clinical examinations were performed by calibrated dental students following WHO detection criteria. Caries indices dmft and DMFT were calculated. Caries Risk Assessment data was collected using an adapted CAMBRA instrument; following the International Caries Care guidelines. Descriptive statistics were performed to analyze the results and Chi-square test, Contingency Coefficient (C) and Corrected Typified Residues were calculated to determine the association between variables. 58% of the total population had dental caries lesions in its more severe stages (cavitation) and 42% were apparently healthy (AHS) without any cavitated lesions. The mean dmft index was 1.34 ± 1.93, and the mean DMFT index was 0.63 ± 1.22. Lesion severity remained between 1-2 teeth affected on both dentitions. A statistically significant association (p = 0.035) between the health condition and toothbrushing was stablished with a degree of dependence of C = 0.144. A positive standardized residual of 2.1 was evident for schoolchildren that experience caries lesion that never brush their teeth and AHS that brushed their teeth more than once. No association (p = 0.081) was found between health condition and intake of sugary snacks and beverages. A severe dental caries experience with a statistically significant association between the health condition and toothbrushing with fluoridated toothpaste 1450 ppm > 1 a day and a positive correlation in schoolchildren that experience caries lesion that never brush their teeth.

To assess the impact of oral conditions on oral health-related quality of life (OHRQoL) in infants in ten Latin America countries (LAC). A cross-sectional study was conducted with 930 pairs of 1-to-3-year-old children/parents from 10 LAC, as a complementary study of the Research Observatory for Dental Caries of the Latin American Region. The scale ECOHIS, previously tested and valid in ten countries, was applied to parents/caregivers of children to measure OHRQoL. Statistical analysis included descriptive data analysis and one-way analysis of variance (ANOVA-One-Way) were performed to compare age groups with OHRQoL. Bootstrapping procedures (1000 re-samplings; 95%CI Bca) were performed. The mean scores of the 'Child Impact' section in the LAC was 4.0(±8.3), in the 'Family Impact' section was 2.0(±4.0), and in overall ECOHIS score was 6.0(±12.0). In the 'Child Impact' section, Argentina 10.0(+2.4) and Venezuela 17.8(±17.5) demonstrated mean scores higher than the LAC total data. In the 'Family Impact' section, the countries with higher mean scores were Argentina 4.9(±2.0), Ecuador 2.1(±3.1) and Venezuela 7.9(±7.8). In the overall ECOHIS score, Argentina 15.1 (±4.1) and Venezuela 25.7(±25.2) has higher mean scores than the values of LAC. There is an association between children's age and parents' report of impact on the OHRQoL (p<0.001). Three-year-olds had a higher mean when compared to one- and two-year-olds, both in the Impact on the Child and Impact on the Family (p<0.001) sections, as well as in the overall ECOHIS (p<0.001). In conclusion, there are differences in OHRQoL among Latin American countries, impacting older children more significantly.

Caries management at the lesion level is dependent on the lesion activity, the presence of a cavitation (either cleanable or non-cleanable), and lesion depth as evaluated via radiographic examination. A variety of non-invasive, micro-invasive, and minimally invasive treatment (with or without restoration) options are available for primary and permanent teeth. Non-invasive strategies include oral hygiene instructions, dietary counseling, and personal as well as professional use of fluoridated products that reduce demineralization and increase re-mineralization. Micro-invasive procedures include the use of occlusal resin sealants and resin infiltrants, while minimally invasive strategies comprise those related to selective removal of caries tissues and placement of restorations. Deep caries management includes indirect pulp capping, while exposed pulp may be treated using direct pulp capping and partial or complete pulpotomy. The aim of the present study was to review available evidence on recommended preventive and restorative strategies for caries lesions in Latin American/Caribbean countries, and subsequently develop evidence-based recommendations for treatment options that take into consideration material availability, emphasize ways to adapt available treatments to the local context, and suggest ways in which dentists and health systems can adopt these treatments.

OBJECTIVE: The aim of the present study was to determine if a sugarless mint containing CaviStat (an arginine bicarbonate calcium carbonate complex) is capable of preventing the development of dental caries in the primary molars and first permanent molars of 10 1/2- to 11-year-old Venezuelan children. METHODS: Two-hundred children were entered into this one-year study who showed the following: (i) age between 10 1/2 and 11 years; (ii) first and second primary molars still present; (iii) sound primary molars or early caries lesions in any of these teeth; and (iv) at least some caries in the primary or permanent teeth as evidence of caries activity. Out of the 200 children initially selected, 195 finished and provided complete data. Children entered into the study were examined and then randomly divided into two groups (A and B), with distribution performed on the basis of the DMFS levels of the first permanent molars. All subjects were examined visually by a single examiner using good artificial light, mirror, and probe. Group A received a sugarless confection containing CaviStat (BasicMints); Group B received a sugarless mint control that contained all ingredients except for the CaviStat. Packaging and appearance of both types of mints were identical, except for their A and B designations. RESULTS: Mean differences in DMFS, defs, and DMFS + defs scores between Groups A and B were determined. In the first permanent molars and some early erupting premolars and second molars, the data showed 75.6% fewer caries in Group A than in Group B children after six months, and 50.7% fewer after 12 months. Corresponding defs scores showed reduced development of dental caries in deciduous molars of 76.7% after six months and 131.3% after 12 months. Combined DMFS and defs scores showed 76.2 and 74.8% fewer caries lesions at six and 12 months, respectively. As exfoliation of primary molars occurred during the study period (approximately equal in the two groups), a proportion correction was made to allow for caries score reductions due to lesions lost because of such exfoliation. When this was done, the results at the end of the study still showed larger caries reductions in Group A than in the Group B subjects, and statistical analyses showed these differences were still highly significant (p < 0.001). Noncavitated caries lesions in the first permanent molars were also determined. These showed once again less caries development in Group A than in Group B subjects, and did so at both six and twelve months (57.0 and 52.4%, respectively). Levels of statistical significance at these times were p = 0.013 and 0.005. CONCLUSION: It was evident from this clinical trial that mint confections containing CaviStat are able to inhibit both caries onset and caries progression. As a result, one can conclude that CaviStat mint confection technology is a simple and economical means for reducing substantially one of the most prevalent diseases in these children.

Introduction: Pediatric ulcerative colitis (CUP), pediatric Crohn's disease (PCD), and pediatric inflammatory bowel disease not classifiable (PIDNCID) have clinical and psychosocial particularities that differentiate them from those of adults and may condition different therapeutic approaches due to possible nutritional, growth and developmental repercussions, representing a challenge for the pediatrician and gastroenterologist. Objective: Develop expert consensus evidence-based recommendations for the timely and safe diagnosis and treatment of Pediatric Inflammatory Bowel Disease (PID) in children under 18 years of age for professionals caring for these patients and healthcare payers. Methodology: Through a panel of experts from the Colombian College of Pediatric Gastroenterology, Hepatology and Nutrition (COLGAHNP) and a multidisciplinary group, 35 questions were asked regarding the clinical picture, diagnosis, and treatment of PID. Through a critical review and analysis of the literature with particular emphasis on the main clinical practice guidelines (CPGs), randomized clinical trials (RCTs), and meta-analyses of the last ten years, from which the experts made 77 recommendations that responded to each of the research questions with their respective practical points. Subsequently, each of the statements was voted on within the developer group, including the statements that achieved > 80%. Results: All statements scored > 80%. PID has greater extension, severity, and evolution towards stenosis, perianal disease, extraintestinal manifestations, and growth retardation compared to adult patients, so its management should be performed by multidisciplinary groups led by pediatric gastroenterologists and prepare them for a transition to adulthood. Porto's criteria allow a practical classification of PID. In CPE, we should use the Paris classification and perform ileocolonoscopy and esophagogastroduodenoscopy, since 50% have upper involvement, using the SES-CD (UCEIS/Mayo in CUP) and taking multiple biopsies. Initial labs should include inflammatory markers and fecal calprotectin and rule out intestinal infections. Treatment, induction, and maintenance of PID should be individualized and decided according to risk stratification. Follow-up should use PCDAI and PUCAI for the last 48 hours. Immunologists and geneticists should evaluate patients with early and infantile PID. Conclusion: A consensus guideline is provided with evidence-based recommendations on timely and safe diagnosis and treatments in patients with ILD.
RESUMO
The objective of this study was to determine the experience of fluorosis and dental caries in 8- 12 year old children that drink water with different fluoride concentrations, from Maiquetía, Vargas State. Four hundred and twenty-one children were evaluated and divided in groups of 84 children each, according with their age (8-9-10-11) but 85 for the age 12. This evaluation was developed by a calibrated dentist using Dean's Index for dental fluorosis examining only the six upper anterior teeth and DMFT/dmft index to determine dental caries, following the criteria established by the WHO. In addition, a social status questionnaire was given to the subjects and samples of water and salt from the communities were collected. Thirty-three per cent of the children in this study were males and 67% were females. Results indicated that the mean DMFT and dmft were 0.91 and 1.88, respectively, showing a total of 2.17 teeth with dental caries being the decayed component, the highest component observed in both dentitions. The mean prevalence of dental fluorosis for the studied population was 16.6%, where the very mild category (8.5%) predominated. Maria May was the most affected school with dental fluorosis (41.5%) and the fluoride concentration in drinking water after analyses was 1.58%. The results of this study indicate the presence of an inverse relationship between fluoride concentrations in the water collected at the schools and the prevalence of dental fluorosis in the permanent dentition of school children, but not in the primary dentition.

OBJECTIVE: Premolars and second permanent molars mainly erupt in children between 10 and 13 years of age. This age range provides a relatively large number of caries-free or near caries-free tooth surfaces at a baseline measurement that can become carious during such trials. Since traditional DMFS scoring does not take the addition of new surfaces into account, the aim of this study was to compare that scoring system to two methods where sound surfaces are included in the scoring. METHODOLOGY: The comparison was done in a cross-sectional caries prevalence study so that caries progression and tooth eruptions (as occurs in a longitudinal investigation) would not confound the methods assessments. A total of 729 children between 10 and 13 years of age were recruited from four public schools in Venezuela and assigned to age groups 10, 11, 12, and 13. Decayed, missing, and filled surfaces (DMFS) of their respective premolar and second molar teeth were scored by one calibrated examiner (CM) using a mirror and probe and the criteria reported by Radike, but with one major modification; that was, avoidance of any forceful probing of suspected non-cavitated pits and fissures for caries lesions. In each subject, traditional DMFS were determined in which sound surfaces were not considered. These scores were compared to the scoring of DMFS plus sound surfaces (DMFSS) as described by Katz, et al. and Huntington. RESULTS: Mean traditional DMFS scores (+/- SEM) obtained for the permanent premolars and second molars of 10-, 11-, 12-, and 13-year-old children were 3.06 +/- 0.27, 3.32 +/- 0.27, 3.44 +/- 0.27, and 5.69 +/- 0.37, respectively. A large difference in these scores was observed between the 12- and 13-year-old children, in contrast to smaller differences between the 10- and 11-, and the 11- and 12-year-olds. Eruption of premolar and second molar teeth examined at the same time showed per cent eruptions as follows: 27.2% at age 10; 60.8% at age 11; 84.9% at age 12; and 95.5% by age 13. Most eruption was observed in the 10- to 12-year-olds, in contrast to the largest DMFS differences appearing between children 12 and 13 years of age. Looked at longitudinally, the incongruence of prior eruption and resulting caries reaching detection levels was about one to two years. All three methods of scoring showed the sharp increment in their respective caries scores between ages 12 and 13, whereas smaller and directionally opposite score changes occurred between years 11 and 12. With the Katz, et al. and Huntington DMFSS methods, the scores between 11 and 12 years decreased, whereas traditional DMFS scoring showed an increase. Although these differences were not large, the pattern of traditional DMFS scoring differed significantly from the other two methods (p < 0.001). CONCLUSION: Traditional DMFS scoring in children between 10 and 13 years of age will not detect the new surfaces, and the resulting extra caries increments that would arise in a clinical trial. With the Katz, et al. or Huntington scoring methods, where these new surfaces are counted, adjustment is made for any such caries rate error. In caries remineralization studies, this could be of significance.

Abstract To assess the impact of oral conditions on oral health-related quality of life (OHRQoL) in infants in ten Latin America countries (LAC). A cross-sectional study was conducted with 930 pairs of 1-to-3-year-old children/parents from 10 LAC, as a complementary study of the Research Observatory for Dental Caries of the Latin American Region. The scale ECOHIS, previously tested and valid in ten countries, was applied to parents/caregivers of children to measure OHRQoL. Statistical analysis included descriptive data analysis and one-way analysis of variance (ANOVA-One-Way) were performed to compare age groups with OHRQoL. Bootstrapping procedures (1000 re-samplings; 95%CI Bca) were performed. The mean scores of the 'Child Impact' section in the LAC was 4.0(±8.3), in the 'Family Impact' section was 2.0(±4.0), and in overall ECOHIS score was 6.0(±12.0). In the 'Child Impact' section, Argentina 10.0(+2.4) and Venezuela 17.8(±17.5) demonstrated mean scores higher than the LAC total data. In the 'Family Impact' section, the countries with higher mean scores were Argentina 4.9(±2.0), Ecuador 2.1(±3.1) and Venezuela 7.9(±7.8). In the overall ECOHIS score, Argentina 15.1 (±4.1) and Venezuela 25.7(±25.2) has higher mean scores than the values of LAC. There is an association between children's age and parents' report of impact on the OHRQoL (p<0.001). Three-year-olds had a higher mean when compared to one- and two-year-olds, both in the Impact on the Child and Impact on the Family (p<0.001) sections, as well as in the overall ECOHIS (p<0.001). In conclusion, there are differences in OHRQoL among Latin American countries, impacting older children more significantly.
Resumo Avaliar o impacto das condições bucais na qualidade de vida relacionada à saúde bucal (QVRSB) em crianças de dez países da América Latina (AL). Foi realizado um estudo transversal com 930 pares de crianças/pais de 1 a 3 anos de 10 países da AL, como estudo complementar do Research Observatory for Dental Caries of the Latin American Region. A escala ECOHIS, previamente testada e validada em dez países, foi aplicada a pais/cuidadores de crianças para mensurar a QVRSB. A análise estatística incluiu análise descritiva de dados e análise de variância unidirecional (ANOVA-One-Way) para comparar grupos etários com QVRSB. Procedimentos de bootstrapping (1000 reamostragens; 95%IC Bca) foram realizados. A pontuação média da seção 'Impacto na Criança' na AL foi 4,0 (±8,3), na seção 'Impacto na Família' foi 2,0 (±4,0) e no escore total do ECOHIS foi 6,0 (±12,0). Na seção 'Impacto na Criança', Argentina 10,0(+2,4) e Venezuela 17,8(±17,5) demonstraram pontuações médias superiores aos dados totais da AL. Na seção 'Impacto na Família', os países com pontuações médias mais altas foram Argentina 4,9(±2,0), Equador 2,1(±3,1) e Venezuela 7,9(±7,8). No escore total do ECOHIS, Argentina 15,1 (±4,1) e Venezuela 25,7(±25,2) apresentaram escores médios superiores aos valores de AL. Houve associação entre a idade das crianças e o relato dos pais de impacto na QVRSB (p<0,001). As crianças de três anos tiveram média maior quando comparadas às de um e dois anos, tanto nas seções 'Impacto na Criança' e 'Impacto na Família' (p<0,001), quanto no escore total ECOHIS (p<0,001). Em conclusão, houveram diferenças na QVRSB entre os países da América Latina, impactando de forma mais significativa as crianças mais velhas.
RESUMO
Abstract Caries management at the lesion level is dependent on the lesion activity, the presence of a cavitation (either cleanable or non-cleanable), and lesion depth as evaluated via radiographic examination. A variety of non-invasive, micro-invasive, and minimally invasive treatment (with or without restoration) options are available for primary and permanent teeth. Non-invasive strategies include oral hygiene instructions, dietary counseling, and personal as well as professional use of fluoridated products that reduce demineralization and increase re-mineralization. Micro-invasive procedures include the use of occlusal resin sealants and resin infiltrants, while minimally invasive strategies comprise those related to selective removal of caries tissues and placement of restorations. Deep caries management includes indirect pulp capping, while exposed pulp may be treated using direct pulp capping and partial or complete pulpotomy. The aim of the present study was to review available evidence on recommended preventive and restorative strategies for caries lesions in Latin American/Caribbean countries, and subsequently develop evidence-based recommendations for treatment options that take into consideration material availability, emphasize ways to adapt available treatments to the local context, and suggest ways in which dentists and health systems can adopt these treatments.

OBJECTIVE: This study assessed the effect of an arginine bicarbonate/calcium carbonate (CaviStat)-containing dentifrice on caries development, mainly in 11- to 12-year-old Venezuelan children over a two-year period. METHODOLOGY: Children (726) with a DMFT between 3 and 6 were examined at baseline, six months, and one and two years using a mirror, probe, and DMFS scoring. Subjects who completed the study consisted of two groups; 304 test and 297 control. The test group received a CaviStat-containing dentifrice, and the controls used a commercially available 1100 ppm fluoride toothpaste. All subjects were instructed to brush three times a day for 1 minute followed by swishing for 30 seconds. RESULTS: After six months, the mean DMFS scores increased only slightly from baseline in both groups, 6.93 +/- 0.22 in the control and 6.59 +/- 0.22 in the test subjects. After one year, the mean DMFS score in the control group rose to 8.00 +/- 0.24 and leveled off at 7.92 +/- 0.30 at two years. In contrast, the mean DMFS score in the test group decreased to 5.50 +/- 0.24 after one year before rising to 6.99 +/- 0.28 at two years. DMFS difference between the two groups was highly significant (p < 0.001), but mainly due to the large difference seen at one year. Dissection of the data showed that the erupted first molars dominated the overall DMFS changes. At the beginning of this study, first molar scores started at high values and showed a pattern thereafter like that seen for the total data. In contrast, premolars/molars, which erupt 4-6 years later (and at the start of the study had a mean DMFS score slightly above zero), showed a clear rise in the DMFS score in the control group during the first year of the study, which continued to rise until the end of the investigation. In contrast, the CaviStat group showed no change in the premolar/second molar DMFS score from baseline during the first year (giving the impression of 100% inhibition at one year), but showed a delayed rise thereafter that paralleled that seen in the controls between one and two years (58.3% inhibition at two years). Reversal of the development of early dental caries lesions in the CaviStat subjects and limitations of the diagnosis of very early caries lesions with standard dental explorers was suggested for the interesting first molar, first year data. Inhibition of caries initiation and caries progression in the CaviStat group was also observed and easier to see in the premolar/second molar, second year data where the DMFS scores were very low at baseline and reversals are not a significant issue. The results were subjected to statistical analysis including analysis of covariance. Largely because of the first year and first molar data, the difference between control and experimental groups was highly significant (p < 0.001). Similar comparison with the later-erupting premolar/molar teeth showed the CaviStat effect was also significant but at a lower level (p < 0.05). The differences could not be due to examiner error since the Kappa for 10% of the subjects randomly selected and re-examined was 0.898 overall and 0.914 for the first molar data. The data also suggested CaviStat inhibition of caries progression because of a slower rate of rise of missing+filled teeth in the CaviStat vs. the control group (p < 0.05). CONCLUSION: A CaviStat-containing toothpaste was more effective both clinically and statistically in inhibiting caries initiation and progression than the fluoride toothpaste control, and manifested its effects differently in the already-erupted first molars than in the later-erupting premolars and second molars.
