  • Dental utilization by children in Hispanic agricultural worker families in

    • Authors: Tracy L Finlayson, Stuart A Gansky, Sara G Shain, Jane A Weintraub
      Abstract: Background:Agricultural worker families encounter multiple barriers to accessing all needed dental care. This study investigated predisposing, enabling, and need factors associated with children’s past year dental utilization among Hispanic agricultural worker families in central California.Methods:Oral health survey and clinical data were collected from families participating in a larger, population-based study in 2006-7. Generalized estimating equation logit regression assessed effects on a dental visit among children aged 0-17 (n=405).  Analyses adjusted for clustering of children in the same household.  Predisposing (socio-demographics), enabling (child’s dental insurance, regular dental care source, caregiver past year dental visit, acculturation level, income, education), and need (caregiver’s oral health rating, perception of cavities, clinically-determined treatment urgency) factors were examined. Results: Half (51%) the children had a past year dental visit, while 23% had never been to a dentist. In the final model, children were less likely to have a past year dental visit if they were foreign-born, male, had caregivers that thought they had cavities or were unsure, and if the dentist recommended treatment ‘at earliest convenience’. Children aged 6-12, with a regular dental care source, and whose caregivers had a recent dentist visit were more likely to have a past year dental visit. Conclusions: Children were more likely to have a past year dental visit if they had a regular source of dental care (OR=4.78, CI=2.51-9.08), and if the caregiver had a past year dental visit (OR=1.88, CI=1.04-3.38). Emphasis should be placed on these two modifiable factors to increase children’s dental utilization.

  • The misuse of meta-analysis of studies in a dental journal

    • Authors: Yong-Geun Choi, Steven E Eckert
      Abstract: Backgrounds: Studies using meta-analysis synthesizing the diverse outcomes of different studies under the same research question have been on the increase due to statistical methodology’s development. Fallacious use of meta-analysis, however, may mislead the dental research community and consumption community. This study, thus, intended to describe the using pattern of six essences of meta-analysis in published studies in a dental journal from 2011 to 2013. Methods: Twelve articles were searched through electronic online and confirmed by hand search as well with two index words including “meta-analysis” and “meta analysis”. While author’s information was blinded, presence of statement corresponding to the six essence of meta-analysis was ascertained twice for precise measurement. Results: Of the 12 articles, 9 used random effect model (75%, 95%CI= 46.8%, 91.1%). 2 studies used both random and fixed model. 1 study did not report the type of model (8.3%). According to the 95% CI, we are 95% confident that between 46.8% and 91.1% of the total meta-analysis studies in the Journal used the random effect model. 16.7% (95%CI=4.7%, 44.8%) specified correctly the criteria of model selection. 41.7% (95%CI=19.3%, 68.1%) used correctly the heterogeneity test. 8.3%(95%CI=1.5%, 35.4%) stated correctly and clearly the criteria of heterogeneity test interpretation. 16.7% (95%CI=4.7%, 44.8%) utilized heterogeneity test’s result, and 100% (95%CI=75.8%, 100%) did not report funnel plot. Conclusions: Remedies to fix the situation are suggested: balance of focus on between the final summarized effect size and the procedures themselves, and collaboration with statistician in thoroughly mindful of essence of meta-analysis.

  • The Relationship Between Social Support and Dentition Status of U.S.

    • Authors: Ying Liu, Mary P. Walker
      Abstract: Background: To investigate whether having a social network and social support directly associated with the dentition status of U.S. Veterans and to measure and assess its possibly indirect effect on the relationship between socioeconomic inequality and dentition status. Materials and Methods: The individuals were U.S. Veterans, aged 40 years and over, taken from the National Health and Nutrition Examination Survey 2005-2008. Dentition status includes the presence of tooth decay, the presence of restoration and number of missing teeth. Social network and support were measured by marital status, number of close friends, and the need for more emotional support, church attendance and financial support. Risk ratios and rate ratios were used to estimate the strength of association between social network, social support and dentition status. Results: (i) Divorced have significantly higher tooth decay rate (1.18 95% CI: 1.21, 1.50); (ii) no church attendance has significantly lower restoration rate (0.66, 95% CI: 0.48, 0.91) and higher missing teeth rate (1.1, 95% CI: 1.06, 1.14). (iii) Veterans who need more emotional support have significantly higher missing teeth rate (1.12, 95% CI: 1.06, 1.17); (iv) financial support is not related to dentition status. Conclusions:  Some indicators of social network and support are highly associated with dentition status of U.S. Veterans; divorced are more likely to have tooth decay than others, and the need for emotional support, the number of close friends and church attendance are linked to the number of missing teeth.
