ABSTRACT
OBJECTIVES: This study evaluates the influence of several determinants on the presence of early childhood caries (ECC) in preschool children living in northern Sardinia, Italy. These determinants include the educational level and occupational status of the parents as a proxy for the socioeconomical level (SES) and behavioral factors (dietary and oral hygiene). METHODS: An observational cross-sectional study was designed with a dental examination and a standardized questionnaire. Five hundred forty-four subjects (260 girls and 284 boys) were enrolled and categorized into two age groups: 359 children were aged 18-47 months and 185 children were aged 48-60 months. RESULTS: The total caries prevalence was 15.99%. Caries risk increased with lower parents' educational level (P = 0.01), increased number of siblings (P < 0.01), the use of bottle feeding (P = 0.02), and the use of a sweetened baby's pacifier at night (P = 0.01). In robust multivariate analysis, a high parental educational level played a protective role on the presence of caries lesion [odds ratio (OR) = 0.51, 95% confidence interval (CI) 0.34-0.78]; the mother's being employed had a positive statistically significant association with the child having decayed, missing, filled tooth surfaces = 0 (OR = 0.64, 95% CI 0.23-0.97). The presence of more than one sibling in the family was associated with caries (OR = 1.70, 95% CI 1.20-2.40). CONCLUSION: ECC prevalence evaluated was similar to other western countries, and SES and behavioral habits influence the development of ECC.

PURPOSE: To compare the clinical outcome of platform switching (PS) and regular platform (RP) implants in bilateral single molar replacements. MATERIAL AND METHODS: This study was designed as a randomised, controlled, split-mouth trial. Eighteen patients, with bilaterally missing single molars had one site randomly assigned to a PS implant or a RP implant. A total of 36 implants were bilaterally installed. Both implants were loaded with screw retained temporary crowns 3 months after implant insertion and with screw retained definitive crowns 3 months later. Outcome measures were implant/crown failure, complications, radiographic marginal bone-level changes, pocket probing depth (PPD) and bleeding on probing (BOP). Clinical data were collected at baseline 6 and 12 months after implant placement. RESULTS: No patients dropped out and no implant failed. No prosthetic or major biological complications were observed. One year after implant placement, mean marginal bone level was 0.93 ± 0.26 mm (95% CI 0.81 to 1.05) in RP group and 0.84 ± 0.23 mm (95% CI 0.73 to 0.95) in the PS group and no statistically significant differences between the two groups were observed (P = 0.18). Mean PPD and BOP values were, 6 and 12 months after implant placement, 2.74 ± 0.49 mm (95% CI 2.51 to 2.97) and 1.28 ± 0.75 (95% CI 0.93 to 1.63) in the RP group, and 2.70 ± 0.38 mm (95% CI 2.53 to 2.88) and 1.39 ± 0.78 (95% CI 1.03 to 1.75) in the PS group respectively, with no statistical differences between groups (P = 0.81 and P = 0.16, respectively). CONCLUSIONS: No statistically significant difference was observed between platform switched and non-platform switched implants.

Oral lesions may be found in patients with Crohn's disease (CD), in a percentage up to 20%. The aim of this study was to investigate a possible relationship between Mycobacterium avium subsp. paratuberculosis (MAP) and oral lesions in CD patients. 23 oral biopsies were examined performing IS900 Nested PCR; 9 of them were positive: 8 from CD patients and 1 from a control. Our purpose is to go on with this study, amplifying the number of subjects examined and testing subjects with oral lesions related to diseases other than CD to verify the specific association between MAP and oral lesions in CD patients.
ABSTRACT
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.
