Trends of mortality due to oral health outcomes in children from 0-19 years of age were assessed Population: Children aged 0 to 19 years of age, whose primary or underlying cause of death was associated with oral disease (The International Classification of Diseases (ICD) 9 codes 520-529 and the ICD 10 codes K00-K14) Data collection: Death certificate data for children 0-19 years of age was extracted from the CDC Wonder mortality database. It included only those underlying causes of death and subsequent causes of death with ICD-9 and ICD-10 codes associated with oral disease (N=535). A second database excluding those deaths due to syndromes associated with craniofacial malformations and accidents was created (N= 240). Age groups were defined according to US Census data and death rates were calculated (overall and per age group) utilizing intercensal denominators. Chi Square test of trend was performed on each age group, the database overall, and the database excluding the syndromes and accidents RESULTS Census Regions of the United States with %Mortality RESULTS CONCLUSIONS There is a downward trend of death associated with poor oral health in children and adolescents from 1979-2004. This trend shows a decrease in the death rates over time. The decrease in death rates is still seen when excluding deaths that involved syndromes We look at the almost 3 decades represented, we see a mean death rate of 3 per 10 million (+ 1.22) in the 80s. The 90s showed a mean of 2.4 deaths per 10 million (+ 0.58). The data from 2000-2004 show a mean death rate of 2 per 10 million (+ 0.50) It is apparent from this time trend study that further investigation from longitudinal studies needs to be accomplished in order to better assess incidence of death in children and adolescents due to poor oral health. It is our hope that our Mortality Database can be utilized for future studies This graph shows a decrease in the death rates over time There is a trend in death rates associated to oral health outcomes in children aged 0-19 from 1979 to 2004 (p = 0.017) This graph shows a decrease in the death rates over time There is a trend in death rates associated to oral health outcomes in children aged 0-19 from 1979- 2004 that were not afflicted with syndromes/accidents (p = 0.003) For more information: Klyoda@u.washington.edu ICD NumberICD Description 522.5 and K04.7Periapical abscess without sinus 528.1Cancrum Oris 529.0Glossitis 529.8Other specified conditions of the tongue 528.3Cellulitis and abscess of oral soft tissues 528.4Cysts of oral soft tissues K02.9Dental caries-unspecified K12.2Cellulitis and abscess of mouth North East 13% South 34% Midwest 28% West 25% METHODS  Mortality rates in the last 3 decades were as follows: 3 deaths per 10 million (+ 1.22) in the 80s 2.4 deaths per 10 million (+ 0.58)in the 90s 2 per 10 million (+ 0.50) from 2000-2004  There was a significant (P=0.017) downward trend in death rates observed in the total population (535)  The test of trend was also significant when deaths from syndromes (associated with craniofacial malformations) and accidents were removed (p = 0.003)  Among the age groups represented, the decrease in mortality only was significant in the 5-9 year age group. All trends that were significant showed a decrease in death rates over time Sample of Underlying Causes of Death in the Study Population RESULTS Percentage of deaths by racial/ethnicity groupPercentage of deaths gender group Percentage of death groups
