The long-term success of the reimplanted teeth is related to the maintenance of periodontal ligament (PDL) cell viability. Dental tissues are unique in comparison to most other tissues in the body due to their marked capacity for regeneration. Understanding the circumstances leading to repair and regeneration in oral tissues has been a formidable challenge. Numerous storage media have been introduced by many authors that help to maintain the PDL cell viability. To present an overview of the various available storage media. A literature search for the past 20 years was performed across the Internet database (Pubmed) and relevant citations using the keywords PDL cell viability, tooth avulsion, storage media, and the combination of all to retrieve around (n=225) citations. Articles that included follow-up of intervention for avulsed and re-implanted teeth were considered (n=44) and some literature review from well-known text books were considered. Literature supports that moist storage appears to be a more productive approach to optimize PDL cell survival. However, no medium is ideal and in vivo studies are inadequate.

Children under the age of 5 years generally spend most of their time with their parents and guardians, especially mothers, even when they attend pre-schools or nurseries. It has been found that young children's oral health maintenance and outcomes are influenced by their parent's knowledge and beliefs. This study was done to assess the mother's knowledge about the oral health of their pre-school children in Moradabad, India. Mothers of children aged 1-4 years, attending the hospital for vaccination or regular checkups in the pediatric division of government hospitals, were invited to participate in the study. A 20-item questionnaire covering socio-demographic characteristics, dietary practices, oral hygiene practices and importance of deciduous teeth, was distributed to their mothers, during their visit to the hospital. Responses of the mothers were recorded on a Likert Scale. The sample comprised 406 mothers, with the mean age of children being 3.8 years. Three hundred (73.8%) mothers had a good knowledge about diet and dietary practices, while only 110 (27.1%) and 103 (25.4%) mothers were found to have a good knowledge about the importance of oral hygiene practices and importance of deciduous teeth, respectively. Mothers with higher educational qualification and information gained through dentist had a better knowledge about child's oral health. Oral hygiene habits and dietary habits are established during pre-school days and the parents, especially mothers, function as role models for their children.

The goal of modern dentistry is to manage non-cavitated carious lesions non-invasively through remineralization in an attempt to prevent disease progression, and to improve strength, esthetics, and function of teeth. The emphasis currently is being given to new technologies for enamel remineralization which suggest the changes in the understanding of dental caries. The aim of this paper is to review the contemporary non-fluoridated systems available for remineralization therapy and ideas for their implementation into clinical practice. A search of articles from "Pubmed" and "Medline" with the keywords Remineralization-demineralization, Casein derivatives, Non-fluoridated remineralizing agents was conducted. A total of 526 abstracts were collected, out of which 172 articles that discussed current technologies of non-fluoridated remineralizing agents were read and 33 most relevant articles were included in this paper. Casein phosphopeptide based technology has been established as a strong non-fluoridated remineralizing agent fulfilling all the criteria of an ideal remineralizing material.

Cheese and yogurt without any added sugar (sucrose) are non-cariogenic and to some extent cariostatic as they increase calcium and phosphorus concentration in dental plaque. Dairy products without added sugar can be recommended as after meal desserts, especially to school children, which would help to reduce the incidence of dental caries.
