Fluoride Use in Caries Prevention in the Primary Care Setting

Dental caries remains the most common chronic disease of childhood in the United States. Caries is a largely preventable condition, and fluoride has proven effectiveness in the prevention of caries. The goals of this clinical report are to clarify the use of available fluoride modalities for caries prevention in the primary care setting and to assist pediatricians in using fluoride to achieve maximum protection against dental caries while minimizing the likelihood of enamel fluorosis.

Maintaining and Improving the Oral Health of Young Children

Oral health is an integral part of the overall health of children. Dental caries is a common and chronic disease process with significant short- and long-term consequences. The prevalence of dental caries for the youngest of children has not decreased over the past decade, despite improvements for older children. As health care professionals responsible for the overall health of children, pediatricians frequently confront morbidity associated with dental caries. Because the youngest children visit the pediatrician more often than they visit the dentist, it is important that pediatricians be knowledgeable about the disease process of dental caries, prevention of the disease, and interventions available to the pediatrician and the family to maintain and restore health.

Sangre de grado Croton palanostigma induces apoptosis in human gastrointestinal cancer cells.

Sangre de grado is an ethnomedicinal red tree sap obtained from Croton spp. that is used to treat gastrointestinal ulcers, cancer and to promote wound healing. To evaluate the potential role of sangre de grado (SdG) in cancer we examined its effects on human cancer cells, AGS (stomach), HT29 and T84 (colon). Viability of cells treated with SdG (10-200 microg/ml) decreased (P<0.01) in a dose dependent manner measured over a 24-h period. Cell proliferation at 48 h decreased (P<0.01) in all cells treated with SdG (>100 microg/ml). When cells in suspension were treated with SdG (100 microg/ml) cell adherence was severely compromised (>85%). Cells treated with SdG (100 microg/ml) underwent apoptosis as detected by nucleus condensation and DNA fragmentation determined by ELISA, and flow cytometry. Morphological changes as assessed by acridine orange. These effects were similar to that observed with Taxol (30 microM). A significant alteration of microtubular architecture was equally observed in both stomach and colon cancer cells exposed to SdG (100 microg/ml). The induction of apoptosis and microtubule damage in AGS, HT29 and T84 cells suggest that sangre de grado should be evaluated further as a potential source of anti-cancer agents.

Management of Dental Trauma in a Primary Care Setting

The American Academy of Pediatrics and its Section on Oral Health have developed this clinical report for pediatricians and primary care physicians regarding the diagnosis, evaluation, and management of dental trauma in children aged 1 to 21 years. This report was developed through a comprehensive search and analysis of the medical and dental literature and expert consensus. Guidelines published and updated by the International Association of Dental Traumatology (www.dentaltraumaguide.com) are an excellent resource for both dental and nondental health care providers.

A pediatric case of severe pandysautonomia responsive to plasmapheresis.

We describe a 13-year-old female with abrupt onset urinary retention progressing rapidly to pandysautonomia with symptoms of postural orthostatic tachycardia syndrome, gastroparesis, anhidrosis, pupillary dysfunction, and abdominal pain. Pandysautonomia has been reported frequently in adults, but is less commonly described in children. Autonomic nervous system dysfunction usually has a self-limiting course with gradual near-complete or complete recovery. Most patients with pure pandysautonomia produce an antibody targeted against the ganglionic nicotinic acetylcholine receptor and titers have been shown to correlate with symptom severity. The clinical presentation described in this report is consistent with a progressive form of acute autoimmune autonomic neuropathy, but she was initially seronegative for known autoantibodies. She responded promptly to plasmapheresis. This case report emphasizes the importance of recognizing features of autonomic nervous system dysfunction and discusses the medical evaluation and treatment options for pediatric patients based on symptom severity.

Curriculum influence on interdisciplinary oral health education and practice

OBJECTIVES Oral diseases are very prevalent across the lifespan and impact overall health, yet are largely preventable. The Smiles for Life (SFL) curriculum was created to educate healthcare providers about oral disease and support integration of oral health and primary care. This study examines SFLs influence on clinical practice and education. METHODS Surveys were sent to registered users of SFL. Users who self-identified as direct care providers (DCPs), or educators, were included in the analysis. RESULTS Survey response rate was 18 percent, with 87 percent identifying as DCPs and 13 percent as educators. Across professions, 85 percent of DCPs reported SFL influencing their practice to some degree, with variance among profession type and experience. DCPs most commonly reported that SFL led them to improve how they conduct oral health activities, with 60 percent performing the activity more skillfully following completion of SFL. Fluoride varnish application was the most common practice behavior initiated, and caries risk assessments was the oral health activity affected to the greatest degree. A majority of educators (94 percent) reported that SFL led them to incorporate or enhance oral health in their teaching. SFL helped educators emphasize the importance of oral health, improved their ability to teach content, raised motivation, and reduced barriers to teaching oral health. CONCLUSIONS Data supports that SFL is positively influencing oral health practice across professions, especially in areas of caries risk assessment and fluoride varnish application. SFL improves the frequency and quality with which DCPs and educators participate in oral health activities, and facilitates oral health inclusion in primary care.
