Making a Community Ready for Oral Health

The challenges of resolving the oral health disparities among children and other vulnerable populations requires a well-organized community safety net, along with a sincere commitment to prioritize the elimination of this common, but preventable, dental disease. Adequate funding for basic health needs, while incorporating oral health care into a comprehensive primary care model in our neighborhoods provides the best chance for a successful outcome. In order to build better communities for our children, improvement in the access and delivery of dental care must be part of the equation

Occlusal caries formation in vitro: comparison of resinmodified glass ionomer with fluoride-releasing sealant

The purpose of this laboratory study was to evaluate caries-like lesion formation in occlusal enamel adjacent to a light-cured resin-modified glass ionomer utilized as a pit and fissure sealant and a conventional light-cured, fluoride-releasing sealant. Fluoride-free prophylaxis was done on occlusal surfaces of 12 caries-free mandibular molar teeth that had not been exposed to the oral cavity. Occlusal surface morphology was examined by SEM on the uncoated specimens. Each tooth was then sectioned into 2 portions buccolingually, producing mesial and distal tooth halve. Occlusal surfaces of mesial tooth halves were prepared for an experimental light-cured resin-modified glass ionomer (RMG) sealant (PH-SE II, ESPE), and for comparison, a light-cured fluoride-releasing pit and fissure (PFS) sealant (Helioseal F, Ivoclar) was placed on occlusal surfaces of the corresponding distal tooth halves. The sealed occlusal surfaces were examined uncoated by SEM to compare RMG and PFS adaptation. After thermocycling in artificial saliva, caries-like lesions were formed in the occlusal surfaces adjacent to RMG and PFS. Longitudinal sections were taken for comparison of lesion formation adjacent to RMG and PFS. Mean lesion depths in occlusal surfaces were 64±17mm for RMG, and 116±27mm for PFS (p&amp;lt;0.05, paired t-test). Occlusal lesions terminated at the point where bonding occurred between the occlusal enamel and RMG or PFS. SEM surface topography demonstrated adequate adaptation of the materials with obliteration of the typical pit and fissure surface morphology by both RMG and PFS. While both the resin-modified glass ionomer and fluoride-releasing sealant materials protected the pit and fissure enamel from caries development, the resin-modified glass ionomer reduced the extent of caries involvement in the adjacent unsealed occlusal incline enamel, when compared with the resin sealant.</jats:p

Living in Limbo: Ethics and Experience in a Conversation About Persistent Oral Lesions

This case report presents a conversation that the authors had with a patient who is suffering from oral lichen planus and oral cancer. The reason that the authors approached the patient for an interview was to find out why he decided to enroll in an experimental study related to his oral cancer. The patient reported that it was "the waiting" that led him to enroll in this study--that is, the pressure of waiting for oral cancer to re-emerge was simply unbearable, and enrolling in this experimental study enabled him to take a more proactive approach to his illness. The authors view this "waiting" as a "limbo experience" and reflect on the implications of this limbo experience for dental ethics and research ethics
