The School Sealant Program: An evaluation of the oral health education component

Dental caries is a common preventable childhood disease leading to severe physical, mental and economic repercussions for children and their families if left untreated. A needs assessment in Harris County reported that 45.9% of second graders had untreated dental caries. In order to address this growing problem, the School Sealant Program (SSP), a primary preventive initiative, was launched by the Houston Department of Health and Human Services (HDHHS) to provide oral health education, and underutilized dental preventive services to second grade children from participating Local School Districts (LSDs). ^ To determine the effectiveness and efficiency of the SSP, a program evaluation was conducted by the HDHHS between September 2007 and June 2008 for the Oral Health Education (OHE) component of the SSP. The objective of the evaluation was to assess short term changes in oral health knowledge of the participants and determine if these changes, if any, were due to the OHE sessions. An 8-item multiple choice pre/post test was developed for this purpose and administered to the participants before and immediately after the OHE sessions. ^ The present project analyzed pre and post test data of 1,088 second graders from 22 participating schools. Changes in overall and topic-specific knowledge of the program participants before and after the OHE sessions were analyzed using the Wilcoxon's signed rank test. ^ Results. The overall knowledge assessment showed a statistically significant (p <0.001) increase in the dental health knowledge of the participants after the oral health education sessions. Participants in the higher scoring category (7-8 correct responses) increased from 9.5% at baseline to 60.8% after the education sessions. Overall knowledge increased in all school regions with the highest knowledge gains seen in the Central and South regions. Males and females had similar knowledge gains. Significant knowledge differences were also found for each of the topic specific categories (functions of teeth, healthy diet, healthy habits, dental sealants; p<0.001) indicating an increase in topic specific knowledge of the participants post-health education sessions. ^ Conclusions. The OHE sessions were successful in increasing the short term oral health knowledge of the participants. ^

Assessment of executive function before and after vitamin D replacement in vulnerable adults who self-neglect

Purpose: Self-neglect (SN) is the inability to maintain self-care needs. It is thought that older adults who have impaired executive function (EF) develop the inability to do self-care and to protect themselves. The specific aims were to (1) determine the feasibility of using multiple EF measures with community-dwelling elders with SN, (2) identify changes in EF between baseline and 5-months in community-dwelling elders with SN who receive 50,000 IU or 400 IU of oral vitamin D monthly and (2) explore changes in specific dimensions of EF between the groups. ^ Methods: Fifty adults, 65 years of age and older, were recruited from Adult Protective Services with confirmed SN. A research nurse administered the following tests at baseline and five-months: Delis-Kaplan Card Sort Test (D-KEFS), Executive Interview (EXIT 25), CLOX Drawing Test (CLOX I, II), Trails Making Test A and B (TMT A & B) and the Mini-Mental State Examination (MMSE). Demographic data was collected at baseline and serum 25-OHD levels were collected at baseline and five-months. ^ Results: Older adults with SN were more likely to fail the CLOX1 and D-KEFS, while passing the MMSE, CLOX II, TMT A & B and the EXIT 25. At five-months, the only statistically significant difference between groups was in the TMT A & B test scores; the control group did better than the treatment group. There was a non-significant increase in serum vitamin D levels for both groups and no difference between groups. ^ Conclusions: Results from this study provide support that individuals who SN will complete a battery of EF tests and that they exhibit the following impairments consistent with executive dysfunction: 'concept generation', 'planning', 'inhibition', and 'spatial working memory'. Utilizing only one EF measure in individuals with intact cognition may result in unidentification of individuals with executive dysfunction, thus delaying necessary treatment. Future studies should attempt to determine different etiologies of executive dysfunction and determine if early treatment can prevent or reverse SN. ^ Key Words: Self-neglect, Executive Dysfunction, Executive Function, Adult Protective Services, Community-dwelling, Vitamin D ^

Maternal exposure to hazardous air pollutants and oral clefts among offspring: Texas, 1999-2008

Birth defects are a leading cause of infant mortality in the United States. About one in 33 births in the United States is diagnosed with birth defects. Common birth defects include neural tube defects, Down syndrome and oral clefts. The present study focused on oral clefts. ^ Oral clefts refer to the malformation of lip, mouth or both. Birth prevalence of oral clefts in Texas is about 11 per 10,000 births. Etiologically, oral clefts have been classified into two groups, cleft lip with or without cleft palate (CL±P) and isolated cleft palate (CP). In spite of their high prevalence and clinical significance, the etiology of oral clefts in humans has not been well understood. Though a number of risk factors have been identified in epidemiological studies, most of them do not explain the majority of the cases. The need to identify novel risk factors associated with oral clefts provided the motivation for this study. The present study focused on maternal exposure to several hazardous air pollutants. A common subgroup of hazardous air pollutants is the volatile organic compounds found in petroleum derivatives. Four important hydrocarbons in this group are benzene, toluene, ethyl benzene and xylenes (BTEX). ^ The specific aim of this study was to evaluate the association between maternal exposure to environmental levels of BTEX and oral clefts among offspring in Texas for the period 1999-2008. ^ A case-control study design was used to assess if maternal exposure to BTEX increased the risk of oral clefts. The Texas Birth Defects Registry provided data on cases of non-syndromic oral clefts delivered in Texas during the period 1999-2008. Census tract level maternal exposure to BTEX concentrations were obtained from the Hazardous Air Pollutant Exposure Model (HAPEM) developed by the U.S. Environmental Protection Agency. Unconditional logistic regression was used to assess the relationship between maternal exposure to BTEX levels and risk of oral clefts in offspring. ^ In the selected population, mothers who had high estimated exposure to any of the BTEX compounds were not more likely to deliver an offspring with oral clefts. Future research efforts will focus on additional birth defects and thorough assessment of additional potential confounders.^
