BackgroundIn recent years, the non-invasive management of non cavitated caries lesions using remineralization systems to repair the enamel have received more attention from the scientific community. Aim: To quantitatively evaluate the remineralization potential of Casein phosphopeptide-amorphous calcium phosphate-fluoride(CPP-ACPF), Tri-calcium phosphate(TCP) & Nano-hydroxyapatite(nHAP) using Scanning Electron Microscopy(SEM) and Energy dispersive X-ray Analysis(EDX).Material and Methods40 enamel specimens were prepared, and immersed in demineralising solution at a pH of 4.4 for 96 hours at 37°C, to induce artificial carious lesions. Remineralization was carried out for a period of 30 days using CPP-ACPF, TCP, nHAP. The specimens were evaluated for calcium and phosphorus content using SEM-EDX.ResultsThe Ca/P mass % after remineralization was significantly higher with CPP-ACP-F and TCP-F followed by nHAP.ConclusionsCPP-ACP-F and TCP can promote significant remineralization of incipient carious lesions. These are excellent delivery vehicles available in a slow release amorphous form to localize calcium, phosphate and fluoride at the tooth surface. Key words:Remineralization, in vitro; CPP-ACP fluoride, Nano-hydroxyapatite, Tri-calcium phosphate, SEM/ EDX.

Treacher Collins syndrome (Mandibulofacial dysostosis) is characterized by deafness, hypoplasia of facial bones (mandible, maxilla and cheek bone), antimongoloid slant of palpebral fissures, coloboma of the lower lid and bilateral anomalies of the auricle. Hypoplasia of the facial bones may be the first indicator of the disorder. We present a case report of Treacher Collins syndrome with their extraoral findings, intraoral findings and their treatment plan. We have also included the various etiological factors, clinical diagnostic aids, and multidisciplinary team approach.

Munident (herbal) dentifrice has better gingival bleeding index compared to standard formulation of toothpaste. Hence, the practice of using herbal dentifrice should be encouraged.

Green tea mouth rinse can be considered safe, economical and used without much concern. However, further studies are recommended.

Objectives: This study estimated the prevalence of early childhood caries (ECC) and related risk factors in a population of immigrant Tibetan preschool children in Bylakuppe of Mysore District; India. Methodology: A cross sectional study was conducted in 500 preschool children between 10 to 72 months of age in and around Bylakuppe of Mysore district; India; using II stage stratified random sampling. The caries experience was recorded using defs and the deft index. Information regarding risk factors for caries was obtained through a structured questionnaire given to mothers/caretakers. Statistical data analysis: The data was statistically analyzed by using "chi-square" test and "ANOVA" test. Results: The prevalence of ECC in the study sample was significantly high. It was 92.2% with the mean defs score of 10.27 and the mean deft score of 6.15 (p<0.001vhs).Higher prevalence of ECC was found, in children with bottle feeding, addition of sugar to bottle content and to regular food, in-between meal snacking habits and increase intake of sweets like chocolate, candies and toffees, lesser frequency of brushing and child brushing unassisted/unsupervised. Reports of regular visits to the dentist were almost absent in the study population. Conclusion: This study demonstrates the high prevalence of ECC in the study population. Development of strategies and protocols; to prevent and manage ECC, based on the risk factors identified for these population, is essential to curb this oral health problem.
