ABSTRACTAn alternate technique of care to prevent, arrest and manage root caries using aqueous silver fluoride followed by stannous fluoride (AgF+SnF2) in aged care is demonstrated by three case studies. With increasing age, the inability to maintain ones own oral care from dementia, illness or frailty and polypharmacy induced salivary gland hypofunction will result in dental caries becoming a progessively greater burden for the elderly. Future generations of elders will live longer and need to maintain many more teeth longer than earlier generations. Both silver diamine fluoride (SDF)and AgF+SnF2 arrest and prevent caries and are easy to use in residential aged care facilities. Clinical differences between SDF and AgF+SnF2 are discussed. However, in aged care, AgF+SnF2 may offer advantages over SDF. AgF+SnF2 used to arrest and prevent caries in children can be modified to provide effective but minimally invasive care for an ageing and frail population. These techniques are rapid, inexpensive and nonthreatening suited to treat frail elders, dementia patients exhibiting challenging behaviours and patients with multiple rapidly progressing decay. Silver fluoride, applied before placing glass‐ionomer cement (GIC) restorations is an important adjunct to the atraumatic restorative technique and may retard caries reactivation more than GIC used alone.

This book presents an up-to-the-minute overview of arsenic and fluoride pollution of soil and groundwater in Pakistan. It includes the author's doctoral dissertation on Lahore as a case study and describes the mechanism of pollution on the basis of the findings in that area. The book highlights the concrete situation in Pakistan - including the severity of the problem, its health effects and the risks posed to the people living in affected areas by these two major pollutants- and points out essential research areas that call for immediate attention. As such, it draws attention to the need for management strategies in the affected areas and offers a valuable reference work on Pakistan for students and researchers alike.

Patients who undergo radiation therapy that includes the salivary glands frequently experience severe xerostomia. The standard of care for these patients who have natural teeth has become daily application of fluoride by means of custom‐fabricated carriers. The purpose of this study was to determine patient compliance with fluoride gel application using carriers.Using a structured verbal questionnaire, we interviewed 76 patients who had completed radiation therapy for head and neck cancer. Thirty of these patients were seen regularly in the dental clinic of the Cancer Agency (group 1); the remaining 46 were not seen on a regular basis (group 2).Overall, 43% of patients reported using fluoride gel regularly (once a day). In group 1, 67% of patients used fluoride regularly, as did 28% of patients in group 2 (p = 0.001). There were no significant differences between the groups in frequency of toothbrushing and use of dental floss. Compliance with the use of fluoride in carriers was not associated with differences in other oral care measures in the two groups, which suggests that fluoride application in carriers achieves limited compliance in relation to daily oral health care measures. Regular follow‐up of patients after radiation therapy is needed to assess their need for, and compliance with, daily fluoride application.
