RESUMO
BACKGROUND: The study was aimed to describe caries prevalence and severity and health inequalities among Italian preschool children with European and non-European background and to explore the potential presence of a social gradient. METHODS: The ICDAS (International Caries Detection and Assessment System) was recorded at school on 6,825 children (52.8% females). Caries frequency and severity was expressed as a proportion, recording the most severe ICDAS score observed. Socioeconomic status (SES) was estimated by mean a standardized self-submitted questionnaire filled-in by parents. The Slope Index of Inequality (SII) based on regression of the mid-point value of caries experiences score for each SES group was calculated and a social gradient was generated, children were stratified into four social gradient levels based on the number of worst options. Multivariate regression models (Zero-Inflated Negative Binomial logistic and logistic regression) were used to elucidate the associations between all explanatory variables and caries prevalence. RESULTS: Overall, 54.4% (95%CI 46.7-58.3%) of the children were caries-free; caries prevalence was statistically significant higher in children with non-European background compared to European children (72.6% vs 41.6% p < 0.01) and to the area of living (p = 0.03). A statistically significant trend was observed for ICDAS 5/6 score and the worst social/behavioral level (Z = 5.24, p < 0.01). Children in the highest household income group had lower levels of caries. In multivariate analysis, Immigrant status, the highest parents' occupational and educational level, only one kid in the family, living in the North-Western Italian area and a high household income, were statistically significant associated (p = 0.01) to caries prevalence. The social gradient was statistically significant associated (p < 0.01) to the different caries levels and experience in children with European background. CONCLUSIONS: Data show how caries in preschool children is an unsolved public health problem especially in those with a non-European background.

This study presents the result of the second National pathfinder conducted in Italy on children's oral health, reporting the prevalence and severity of caries in 12-year old children and describing the caries figure related to the socioeconomic inequalities, both at individual level and macroeconomic level. The two-digit codes related to ICDAS (International Caries Detection and Assessment System) for each tooth and the gingival bleeding score were recorded at school on 7,064 children (48.97% males and 51.03% females). The Gross National Product (GNP) per capita, the Gini Index and Unemployment rate in each Italian section, parents' educational levels, working status, smoking habit and their ethnic background were recorded. Zero-inflated-negative-binomial (ZINB) models were run, using caries-free teeth, teeth with enamel lesions, cavitated lesions and restorations as functions of socioeconomic explanatory variables, to evaluate the effects of justifiable economic factors of geographical distribution. The mean number of enamel lesions, cavitated lesions and filled per teeth were statistically significant (p < 0.01) dissimilar among the Italian section. GNP per capita, Gini Index and Unemployment rate were significantly correlated to ICDAS scores and filled teeth. Important differences in ICDAS score values remain among children from different socioeconomic backgrounds. Efforts should be made to improve awareness and knowledge regarding oral health practice and to implement preventive programs and access to dental services in Southern Italy where the disease is still unresolved.

BACKGROUND: Assessing caries risk is an essential element in the planning of preventive and therapeutic strategies. Different caries risk assessment (CRA) models have been proposed for the identification of individuals running a risk of future caries. This systematic review was designed to evaluate whether standardized caries risk assessment (CRA) models are able to evaluate the risk according to the actual caries status and/or the future caries increment. METHODS: Randomized clinical trials, cross-sectional studies, cohort studies, comparative studies, validation studies and evaluation studies, reporting caries risk assessment using standardized models (Cariogram, CAMBRA, PreViser, NUS-CRA and CAT) in patients of any age related to caries data recorded by DMFT/S or ICDAS indices, were included. PubMed, Scopus and Embase were searched from 2000 to 2016. A search string was developed. All the papers meeting the inclusion criteria were subjected to a quality assessment. RESULTS: One thousand three-undred ninety-two papers were identified and 32 were included. In all but one, the Cariogram was used both as sole model or in conjunction with other models. All the papers on children (n = 16) and adults (n = 12) found a statistically significant association between the risk levels and the actual caries status and/or the future caries increment. Nineteen papers, all using the Cariogram except one, were classified as being of good quality. Three of four papers comprising children and adults found a positive association. For seven of the included papers, Cariogram sensibility and specificity were calculated; sensibility ranged from low (41.0) to fairly low (75.0), while specificity was higher, ranging from 65.8 to 88.0. Wide 95% confidence intervals for both parameters were found, indicating that the reliability of the model differed in different caries risk levels. CONCLUSIONS: The scientific evidence relating to standardized CRA models is still limited; even if Cariogram was tested in children and adults in few studies of good quality, no sufficient evidence is available to affirm the method is effective in caries assessment and prediction. New options of diagnosis, prognosis and therapy are now available to dentists but the validity of standardized CRA models still remains limited.

BACKGROUND: This survey aims to evaluate the prevalence and severity of tooth loss in the Italian elderly population living in nursing homes and to associate the oral data with demographic, socioeconomic factors, the Mini-Mental State Examination (MMSE), the Body Mass Index (BMI) and the Mini Nutritional Assessment (MNA) scores. METHODS: A cluster sample method was performed using each nursing home as a cluster. Twenty-three nursing homes located in the five areas of the Italy (North-West, North-East, Centre, South and Islands) were selected. An informed consent to participate was distributed by the personnel of the selected nursing homes and signed directly by subjects/caregivers; 2114 forms were distributed, 1998 forms signed and finally 1976 subjects were examined. Chewing ability was scored as good (≥10 functional units (FUs)), sufficient (7-10 FUs), and insufficient (< 7 FUs). The presence of prosthetic dental restorations was summarized as: absent of prosthesis, fixed prosthesis, removable prosthesis, combined prosthesis. Age, gender, socioeconomic status, MMSE, BMI and MNA were obtained from medical charts. RESULTS: Almost three quarters of the subjects were ≥ 80 years old (74.37%) and women (74.04%). The prevalence of edentulism was 42.10% with a large variation among the five areas of Italy (from 34.43% in Centre to 53.46% in North-West). Insufficient presence of FUs was preeminent in each age group (prevalence 42.10%) and statistically associated to age and to female gender (p < 0.01). Overweight/obese (7.47%) subjects showed the highest FUs. Area of living, MMSE (both < 0.01), BMI (p = 0.01) were statistically significant associated to the type of prosthetic dental restorations in the oldest group. Subjects with no mental impairment showed the highest percentage of prosthetic dental restorations (32.36%). CONCLUSIONS: More than half of the sample has an insufficient number of functional units for chewing and this is more pronounced in females. The presence and the type of prosthetic dental restorations are linked to cognitive impairment: the higher is the mental impairment the higher is the number of subjects with absence of prosthetic restorations. The findings of this national survey highlight the need for public health policy, aiming to increase awareness regarding oral health though health education.

OBJECTIVES: To analyse CT use in recent years in a high-density Italian area (±10 million inhabitants, including 1 million children), focusing on developing age. METHODS: Retrospective analysis of records from HealthCare IT System, covering >400 hospitals and clinics. Description of CT use between 2004-2014 in emergency and outpatient care and assessment of radiation exposure trend. RESULTS: Over 9 million scans were performed. Emergency procedures showed a global increase of 230 %, mainly head examinations. In the global outpatient setting, the annual number of CT scans/person increased ±19 %. A moderate increase in CT examinations was observed in the developing age population, while a remarkable increase in dental, chest and abdominal procedures occurred for the 10- to 30-year age range. The increase in mean annual dose/capita in the global patient pool was approximately 42 %, increasing from 0.72-1.03 mSv. The population rate receiving an annual CT radiation dose/capita higher than 1 mSv tripled in the 11-year interval, increasing from 16-48 %. CONCLUSIONS: The remarkable increase in radiation exposure raises a special concern for teenagers and young adults, whose risk tends to be underestimated. The fivefold increase in dental CTs in the younger age groups requires further investigations. KEY POINTS: ⢠Literature highlights a remarkable increase in CT use over the last decades. ⢠The paediatric age had higher exposure to X-ray risk. ⢠A detailed retrospective analysis of more than 9 million scans was performed. ⢠Dental, chest, abdominal procedures increased remarkably in 10- to 30-year age range. ⢠This study raises concern about exposure for teenagers and young adults.

The quali-quantitative characterization of the oral microbiota is crucial for an exhaustive knowledge of the oral ecology and the modifications of the microbial composition that occur during periodontal pathologies. In this study, we designed and validated a new phylogenetic DNA-microarray (OralArray) to quickly and reliably characterize the most representative bacterial groups that colonize the oral cavity. The OralArray is based on the Ligation Detection Reaction technology associated to Universal Arrays (LDR-UA), and includes 22 probe sets targeted to bacteria belonging to the phyla Firmicutes, Proteobacteria, Actinobacteria, Bacteroidetes, Fusobacteria, and Spirochaete. The tool is characterized by high specificity, sensitivity and reproducibility. The OralArray was successfully tested and validated on different oral samples (saliva, lingual plaque, supragingival plaque, and healing cap) collected from 10 healthy subjects. For each specimen, a microbial signature was obtained, and our results established the presence of an oral microbial profile specific for each subject. Moreover, the tool was applied to evaluate the efficacy of a disinfectant treatment on the healing caps before their usage. The OralArray is, thus, suitable to study the microbiota associated with various oral sites and to monitor changes arising from therapeutic treatments.

OBJECTIVES: The caries preventive effect of long-term use (1 year) of low-dosage (2.5 g/die) of xylitol chewing gum in a high-caries-risk adult population was evaluated. MATERIALS AND METHODS: In this randomized clinical trial, 179 high-caries-risk adults were assigned to two experimental groups, xylitol and polyols. Caries status, salivary mutans streptococci (MS), and plaque pH were re-evaluated after 2 years from baseline in 66 xylitol and 64 polyol subjects. Outcomes (the net caries increment for initial, moderate, and extensive caries lesions and for the caries experience) were evaluated using the nonparametric Mann-Whitney U test. RESULTS: The total caries experience increment was 1.25 ± 1.26 in the xylitol group and 1.80 ± 2.33 in the polyol group (p = 0.01). Subjects treated with xylitol chewing gums had a reduction of risk rate at tooth level of 23% with respect to those treated with polyols with a number needed to treat of 55 teeth. The area under the curve at pH 5.7 was statistically significantly lower (p = 0.02) during the experimental period in the xylitol group. A decrease of the concentration of salivary MS was noted in the xylitol group (p < 0.01). CONCLUSIONS: Subjects using the low-dose xylitol chewing gum showed a significantly lower increment of initial and extensive caries lesions and overall a lower increment of caries experience. CLINICAL RELEVANCE: One-year use of chewing gums provides an effective means for the prevention of caries disease. TRIAL REGISTRATION NUMBER: NCT02310308.

Objective To explore the potential presence of a social/behavioural gradient in dental health among Italian adults using a cross-sectional study. Methods Caries indices were recorded among 480 subjects (52.9% men, 47.1% women) who also completed a structured self-administered social and behavioural questionnaire. A social/behavioural gradient was generated as the sum of the worst circumstances recorded on the questionnaire (cariogenic diet, smoking, lowest occupational profile, brushing teeth < twice daily, lowest educational level, uneven dental examination attendance). Results Caries figures (DMFT) and the number of filled sound teeth (FS-T) were statistically significantly linked to the social/behavioural gradient (DMFT: χ2(9) = 20.17 p = 0.02, Z = 0.02 p = 0.99; FS-T: χ2(9) = 25.68 p < 0.01, Z = -4.31 p < 0.01). DMFT was statistically significantly associated with gender and with social and behavioural variables. FS-T was higher in women (p = 0.03) and was linked to smoking ( p < 0.01). Conclusions The proposed social/behavioural gradient demonstrated how subjects reporting the worst circumstances on the questionnaire exhibited the worst dental health. The use of the gradient demonstrates that health promotion and prevention cannot be compartmentalized.

BACKGROUND: Subjects with Autism Spectrum Disorders (ASDs) have often difficulties to accept dental treatments. The aim of this study is to propose a dental care protocol based on visual supports to facilitate children with ASDs to undergo to oral examination and treatments. MATERIAL AND METHODS: 83 children (age range 6-12 years) with a signed consent form were enrolled; intellectual level, verbal fluency and cooperation grade were evaluated. Children were introduced into a four stages path in order to undergo: an oral examination (stage 1), a professional oral hygiene session (stage 2), sealants (stage 3), and, if necessary, a restorative treatment (stage 4). Each stage came after a visual training, performed by a psychologist (stage 1) and by parents at home (stages 2, 3 and 4). Association between acceptance rates at each stage and gender, intellectual level, verbal fluency and cooperation grade was tested with chi-square test if appropriate. RESULTS: Seventy-seven (92.8%) subjects overcame both stage 1 and 2. Six (7.2%) refused stage 3 and among the 44 subjects who need restorative treatments, only three refused it. The acceptance rate at each stage was statistically significant associated to the verbal fluency (p=0.02; p=0.04; p=0.01, respectively for stage 1, 3 and 4). In stage 2 all subjects accepted to move to the next stage. The verbal/intellectual/cooperation dummy variable was statistically associated to the acceptance rate (p<0.01). CONCLUSIONS: The use of visual supports has shown to be able to facilitate children with ASDs to undergo dental treatments even in non-verbal children with a low intellectual level, underlining that behavioural approach should be used as the first strategy to treat patients with ASDs in dental setting.

BACKGROUND: Lack of knowledge is the major reason for non-compliance with correct healthcare-associated infections (HAI) prevention procedures. The aim of this study was to evaluate knowledge of the Dental School (DSS) and Dental Hygiene (DHS) students with regard to the prevention of HAI, as basic knowledge for improving and harmonizing the educational content in the different Italian Universities. METHODS: A cross-sectional study was carried out using an anonymous questionnaire that was completed by DSS (I, II, III, IV, and V year) in seven Universities and DHS (I, II, and III year) in three Universities. The questions dealt with three specific areas: healthcare-associated infections, standard precautions and hand hygiene. Factors associated with an unacceptable level of knowledge (score <17.5) were analyzed using a logistic regression model. A p value <0.05 was considered to be significant. RESULTS: Five hundred and four questionnaires were collected: 81.5% for DSS and 18.5% for DHS. Mean overall score (±DS) achieved by the total number of students was 18.2±2.93 on an overall perfect score of 25; 18.2±3.04 for DSS and 17.8±2.31 for DHS. Stratifying by area, the average score 2.7±1.07 (53%) for HAI, 10.3±1.61 (85.9%) for standard precautions, and 5.2±1.44 (64.8%) for hand hygiene was observed. A significantly different level of knowledge (p<0.001) between DSS and DHS was observed only for HAI (2.8±1.07 for DSS vs 2.1±0.96 for DHS). Significant differences among the academic years were found only for DSS concerning HAI and standard precautions. The logistic regression model showed that an age <23 years was a risk factor for lack of knowledge on HAI, but a protective factor for lack of knowledge about standard precautions and hand hygiene; attending DH degree course was associated with lack of knowledge on HAI. CONCLUSIONS: Although the overall score obtained both by DSS and DHS indicated an acceptable level of knowledge, lack of knowledge was highlighted, in particular, for hand hygiene. Therefore, it is necessary to implement and validate effective teaching models in undergraduate courses in order to provide the scientific basis and the theoretical and practical preparation for the prevention and control of HAI.

The aim of this study was to determine the variability of TD in children undergoing HSCT. Cases were identified as consecutively enrolled children in the period January 2011-January 2013 among patients attending the Paediatric Department of Spedali Civili of Brescia and all candidates to HSCT. The TST was conducted in two phases: identification of threshold values and identification of perceived stimulus intensity. Sixteen sapid solutions with four flavors (sucrose, sodium chloride, citric acid, and quinine hydrochloride) at four different concentrations were administered in a random sequence. The same protocol was administered at different time intervals: before starting the conditioning therapy (T0), during the conditioning therapy (T1) (two times), and every three months (two times) after engraftment post-HSCT (T2). A p-value < 0.05 was considered statistically significant. Fifty-one children (29 female and 22 male, mean age 5.2 ± 0.7 yr) were enrolled. Threshold value means for the four flavors increased during HSCT conditioning therapy (T1) (p < 0.01); intensity of perceived stimulus decreased during HSCT conditioning therapy (p < 0.01). At six months after engraftment (T2), both parameters had returned to starting values (T0). Changes in taste perception in children undergoing HSCT seem to occur especially during the conditioning therapy and resolve in about six months after engraftment post-HSCT.

OBJECTIVE: This randomized double-blind in vivo pilot study has evaluated the effects of a toothpaste containing fluoride (control) versus toothpaste containing fluoride, triclosan, cetylpyridinium chloride and essential oils (experimental) in controlling supragingival dental plaque and bleeding on probing in a sample of healthy schoolchildren. METHOD AND MATERIALS: In total, 48 children (8 to 10 years) were selected and randomly divided into two groups (experimental and control), using the two different toothpastes twice a day for 2 minutes each for a 4-week period. The investigation included an evaluation of plaque quantity, using the Turesky modified Quigley-Hein method, and bleeding on probing that was recorded dichotomously. The unit of analysis was set at the gingival site level. Plaque Index and bleeding on probing were analyzed using distribution tables and chi-square test. A generalized estimating equation was used to estimate the parameters of a generalized linear model with a possible unknown correlation between outcomes. RESULTS: In total, 40 schoolchildren completed the trial. Considering each group separately, a statistically significant difference in plaque scores was recorded for both treatments (z-test = 9.23, P < .01 for the experimental toothpaste; and z-test = 7.47, P < .01 for the control toothpaste). Nevertheless, the effect over time was higher for the experimental toothpaste than for the control one (3.38 vs 1.96). No statistically significant results were observed regarding bleeding on probing. CONCLUSION: The 4-week use of the experimental toothpaste seems to produce higher plaque reduction compared to fluoridated toothpaste without other antibacterial ingredients. This finding has to be confirmed in a larger study.

PURPOSE: Oral health remains a neglected area and its political priority on most national agendas is low. This analysis aimed to identify the political priority of oral health in Italy. BACKGROUND: Italian public health services are decentralised at the regional level and are financed by both central and local authorities. Despite certain legally guaranteed public oral health services, access to oral health care seems to be inhomogeneous. METHODS: Appraisal of the political priority of oral health in Italy uses the Political Power Framework as proposed by Shiffman and Smith. RESULTS AND DISCUSSION: There is no clear mandate for leadership or coordination within the oral health sector, resulting in fragmentation and in dominance of the private sector. As a consequence, oral diseases are mainly addressed through a curative rather than a preventive public health approach. Current, systematic and representative data are lacking. Therefore, the real burden of oral diseases is unknown and thus cannot be addressed adequately. Evidence-based, cost-effective and sustainable population-wide public dental health interventions are not implemented on a large scale, and growing inequities in terms of access to care are not seen as a concern. CONCLUSION: Lack of relevant policies with a public health focus, absence of systematic oral health surveillance and limited access to care for large population groups are strong indicators that oral health is not a political priority. However, opportunities in the wider political environment could be used to facilitate analysis, discussion and change in order to improve political priority of oral health in Italy.

Evidence from the literature has shown that people with a lower socioeconomic status enjoy less good health than people with a higher socioeconomic status. The Italian deprivation index (DI) was used with the aim to evaluate the association between the DMFT index and risk factors for dental caries, including city population and DI. The study included 4,305 12-year-old children living in 38 cities classified by demographic size as small, midsize and large. Zero-inflated negative binomial multilevel regression models were used to assess risk factors for DMFT and to address excess of zero DMFT and overdispersion through a Bayesian approach. The difference in the average level of DMFT among children living in cities with different DI quintile was not statistically significant (p = 0.578). The DI and ln(population), included as city-level fixed effects in the two-level variance components model, were not statistically significant. Consuming sweet drinks on average increased the mean DMFT of a susceptible child, while having a highly educated mother reduced it. Unobserved heterogeneity among cities was detected for the probability to be non-susceptible to caries (city-level variance = 0.26 with 95% credibility interval 0.09-0.57), while no territorial effect was found for the mean DMFT of the susceptible children. Our results suggest that the DI and city population did not play a role in explaining between-city variability. Interventions against social deprivation can be influential on the perception of oral health in Italian 12-year-old children to the extent that they can also affect individual level factors.

OBJECTIVE: The aim of this randomized, single-blind, splitmouth design, clinical trial was to evaluate the effectiveness in plaque removal of two brushing methods, the vertical and the horizontal, in a sample of healthy young adults. METHOD AND MATERIALS: Forty-nine subjects were enrolled and 43 completed the study. All subjects abstained from oral hygiene practices for 48 hours. Plaque and gingival abrasions were recorded according to the Rustogi Modified Navy Plaque Index (RMNPI) and the van der Weijden method by one calibrated examiner before and immediately after the brushing session. A dental hygienist performed the two brushing methods using a randomized split-mouth design. The average plaque scores from the whole mouth, interproximal surfaces, and gingival margin were obtained before and after brushing, and the differences were evaluated using one-way analysis of variance. RESULTS: The differences in mean plaque scores between pre- and postbrushing were statistically significant for both methods. Considering the interbrushing differences, the vertical method produced lower plaque scores compared to the horizontal for the whole mouth (P=.02). In the interproximal surfaces, the vertical method removed more plaque compared to the horizontal one (P<.01). In the gingival margin no statistically significant differences in plaque scores were recorded. Only 10 gingival abrasions were registered, mainly produced by the horizontal method. CONCLUSION: RESULTS suggest that both toothbrushing methods are effective in plaque removal; nevertheless, the vertical brushing method has demonstrated to remove more plaque from the interproximal surfaces than the horizontal method.

BACKGROUND: Several maternal health determinants during the first period of life of the child, as feeding practice, smoking habit and socio-economic level, are involved in early childhood health problems, as caries development. The potential associations among early childhood caries, feeding practices, maternal and environmental smoking exposure, Socio-Economic Status (SES) and several behavioral determinants were investigated. METHODS: Italian toddlers (n = 2395) aged 24-30 months were recruited and information on feeding practices, sweet dietary habit, maternal smoking habit, SES, and fluoride supplementation in the first year of life was obtained throughout a questionnaire administered to mothers. Caries lesions in toddlers were identified in visual/tactile examinations and classified using the International Caries Detection and Assessment System (ICDAS). Associations between toddlers' caries data and mothers' questionnaire data were assessed using chi-squared test. Ordinal logistic regression was used to analyze associations among caries severity level (ICDAS score), behavioral factors and SES (using mean housing price per square meter as a proxy). RESULTS: Caries prevalence and severity levels were significantly lower in toddlers who were exclusively breastfed and those who received mixed feeding with a moderate-high breast milk component, compared with toddlers who received low mixed feeding and those exclusively fed with formula (p < 0.01). No moderate and high caries severity levels were observed in an exclusively breastfed children. High caries severity levels were significantly associated with sweet beverages (p < 0.04) and SES (p < 0.01). Toddlers whose mothers smoked five or more cigarettes/day during pregnancy showed a higher caries severity level (p < 0.01) respect to those whose mothers did not smoke. Environmental exposure to smoke during the first year of life was also significantly associated with caries severity (odds ratio =7.14, 95% confidence interval = 6.07-7.28). No association was observed between caries severity level and fluoride supplementation. More than 50% of toddlers belonging to families with a low SES, showed moderate or high severity caries levels (p < 0.01). CONCLUSIONS: Higher caries severity levels were observed in toddlers fed with infant formula and exposed to smoke during pregnancy living in area with a low mean housing price per square meter.

OBJECTIVES: A double-blind, randomised, placebo-controlled clinical trial was performed to validate the hypothesis that the use of lozenges containing Lactobacillus brevis CD2 (Inersan®, CD Investments srl) may reduce plaque pH, salivary mutans streptococci (ms) and bleeding on probing, during a 6-week period, in a sample of high caries risk schoolchildren. METHODS: A total of 191 children (aged 6-8 years), presenting two to three carious lesions and a salivary ms concentration of ≥10(5) CFU/ml, were enrolled and divided into two groups, an L. brevis CD2 lozenge group and a no L. brevis lozenge group, and examined at baseline (t0), after 3 weeks (t1), after 6 weeks of lozenge use (t2) and 2 weeks after the cessation of lozenge use (t3). Plaque pH was assessed using the microtouch technique following a sucrose challenge. The area under the curve (AUC5.7 and AUC6.2) was recorded. Salivary ms were counted, and bleeding on probing was assessed. RESULTS: At t0, the plaque-pH and ms concentration values were similar in both groups. Mean areas (AUC5.7 and AUC6.2) were significantly greater in the control group at t1, t2 and t3. L. brevis CD2 lozenges significantly reduced salivary ms concentrations and bleeding. The subjects from the test group showed a statistically significant decrease (p = 0.01) in salivary ms concentration. At t2, a statistically significantly lower bleeding value was recorded in the test group compared with the control group (p = 0.02). CONCLUSIONS: Six weeks' use of lozenges containing L. brevis CD2 had a beneficial effect on some important variables related to oral health, including a reduction in plaque acidogenicity, salivary ms and bleeding on probing.

OBJECTIVES: The hypothesis was that the daily use of a high dose of a xylitol chewing gum for 6 months would reduce the increment of decayed permanent first molar surfaces (ΔD6S) in high-risk schoolchildren after 2 years. METHODS: In this randomised, clinical trial, 204 schoolchildren with a high caries risk were assigned to two experimental groups, xylitol and non-xylitol. Caries status, salivary mutans streptococci, and lactobacilli were re-evaluated 2 years later in 74 xylitol-treated and 83 non-xylitol-treated schoolchildren. Differences in mean ∆D6S between groups registered at baseline and at follow-up were evaluated using the nonparametric Mann-Whitney U test. RESULTS: Outcome was the development of detectable carious lesions initial (D1-D2) and manifest (D3) in the permanent first molars. In the xylitol group, the difference in proportion of children with decayed first permanent molars at baseline and follow-up was 1.43% for manifest lesion and 2.86% for initial lesions; while in the non-xylitol group was 10.26% (p < 0.01) and 16.66% (p < 0.01), respectively. A statistically significant difference regarding means was also observed in the non-xylitol group: the ∆D6S for manifest lesion was 0.18 (p = 0.03) and 0.67 (p = 0.02) for initial lesion. CONCLUSION: The use of a chewing gum containing a high dose of xylitol for a period of 6 months has been shown to produce a long-term effect on caries development in high caries-risk children. CLINICAL RELEVANCE: A school-based preventive programme based on 6 months' administration of a high dose of xylitol via chewing gum proved to be efficacious in controlling caries increment in high-risk children.

OBJECTIVE(S): The aim of this study was to explore the relationship between periodontal health and pregnancy outcomes in a large cohort of Italian postpartum women. METHODS: 750 postpartum women were enrolled in a case-control study within 5 days from delivery at three Italian obstetric clinics. Cases were defined as those mothers who delivered an infant weighing under 2500 g (LBW) and/or had premature delivery and/or delivered small for gestational age newborns (SGA) and/or experienced preeclampsia/pregnancy induced hypertension (PE/PIH) or preterm premature rupture of membranes (pPROM) during pregnancy. All women received comprehensive oral and dental examination. Associations between adverse pregnancy outcome and exposures of interest were evaluated by the use of multivariate logistic regression models to estimate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: There was no significant difference between cases and controls with respect to country of birth, age, place of residence, educational achievement, smoking, and periodontal status. By definition, infant birth weight [2,750 g (IQR = 2,300-3,200 g) and 3,275, (IQR = 3,010-3,538 g) p < 0.001, respectively] and gestational age at delivery [259 days (IQR = 245-273) and 273 days (IQR = 266-280), p < 0.01, respectively] were significantly lower in cases than in controls. In multivariate analyses, a borderline association was found between poor obstetric outcomes and current smokers (OR: 1.5; 95% CI: 0.1-2.5). Finally, after adjusting for smoking status neither country of birth, nor age or place of residence or education or periodontitis were associated with a significantly increased risk of adverse pregnancy outcome. CONCLUSION(S): Our data failed to demonstrate the association between periodontitis and an adverse pregnancy outcome such as preterm birth, low birth weight, preeclampsia, intrauterine growth restriction, and premature rupture of membranes.
