BackgroundThis study evaluated the impact of anticipatory guidance on the caries incidence of 2–3-year-old preschool children and their 4–6-year-old siblings, as well as on their mothers’ oral health literacy, as compared to the conventional Ministry of Health (MOH) programme.MethodsThis quasi-experimental study was conducted at two government dental clinics in Batu Pahat District, Malaysia. The samples comprised of 478 mother-child-sibling trios (233 families in the intervention group, and 245 families in the control group). An oral health package named the Family Dental Wellness Programme (FDWP) was designed to provide dental examinations and oral health education through anticipatory guidance technique to the intervention group at six-month intervals over 3 years. The control group received the standard MOH oral health education activities. The impact of FDWP on net caries increment, caries prevented fraction, and mother’s oral health literacy was assessed after 3 years of intervention.ResultsChildren and siblings in the intervention group had a significantly lower net caries increment (0.24 ± SD0.8; 0.20 ± SD0.7) compared to the control group (0.75 ± SD1.2; 0.55 ± SD0.9). The caries prevented fraction for FDWP was 68% for the younger siblings and 63.6% for the older children. The 2–3-year-old children in the intervention group had a significantly lower incidence of white spot lesions than their counterpart (12% vs 25%, p < 0.05). At three-year follow-up, there were significant increments in the oral health literacy scores of mothers in the intervention group compared to the control group.ConclusionThe FDWP is more effective than the standard MOH programme in terms of children’s and siblings’ caries incidence and mother’s oral health literacy.Trial registrationClinicalTrials.gov NCT03478748.

Perovskite-structured lead titanate thin films have been grown on FTO-coated glass substrates from a single-source heterometallic molecular complex, [PbTi(μ2-O2CCF3)4(THF)3(μ3-O)]2 (1), which was isolated in quantitative yield from the reaction of tetraacetatolead(IV), tetrabutoxytitanium(IV), and trifluoroacetic acid from a tetrahydrofuran solution. Complex 1 has been characterized by physicochemical methods such as melting point, microanalysis, FTIR, (1)H and (19)F NMR, thermal analysis, and single-crystal X-ray diffraction (XRD) analysis. Thin films of lead titanate having spherical particles of various sizes have been grown from 1 by aerosol-assisted chemical vapor deposition at 550 °C. The thin films have been characterized by powder XRD, scanning electron microscopy, and energy-dispersive X-ray analysis. An optical band gap of 3.69 eV has been estimated by UV-visible spectrophotometry.

Perovskite-Structured PbTiO 3 Thin Films Grown from a Single-Source Precursor.-The complex [PbTi(μ2-O2CCF3)4(thf)3(μ3-O)]2 (I) is prepared in nearly quantitative yield by reaction of Pb(OAc)4, Ti(OBu)4, and TFA in THF. Perovskite-type PbTiO3 thin films are grown on F-doped SnO2 coated glass substrates by decomposing the deposited (by aerosol-assisted CVD) single-source complex (I) at 550°C. The thin films are characterized by powder XRD, scanning electron microscopy, and energy-dispersive X-ray analysis. An optical band gap of 3.69 eV is estimated by UV/vis spectrophotometry. -(MANSOOR, M. A.; ISMAIL, A.; YAHYA, R.; ARIFIN, Z.; TIEKINK, E. R. T.; WENG, N. S.; MAZHAR*, M.; ESMAEILI, A. R.; Inorg.
