Oral health risk factors and overall dental treatment needs for incoming air force recruits.

OBJECTIVE: To determine if relationships exist between the total dental treatment needs of incoming Air Force recruits and non-clincal demographic and oral-health related factors. METHODS: Data from the 2018 Air Force Recruit Oral Health Study (ROHS) was used, an anonymized sample of 1330 AF recruits that included a comprehensive oral exam and survey collecting demographic and oral health behavior information. The primary outcome variable was the total number of dental treatment needs for recruits, and independent predictor variables included select socio-demographic factors and wellness behaviors. Along with descriptive statistics, a multivariable negative binomial regression analysis was performed to assess the relationship between variables with a normalized weight making the final results representative of all incoming recruits. RESULTS: The final adjusted analysis showed that an incoming recruit's self-rated oral health, dental coverage prior to enlistment, need for a dental visit within the last 12 months, sugar intake, and tobacco use increased their risk for dental treatment needs. CONCLUSION: This is the first study to assess the relationship between specific risk indicators and increased dental treatment needs while adjusting other related covariates. Factors associated with dental treatment needs were identified that provide Air Force leaders with actionable information to directly improve recruit oral health and military readiness by identifying new airmen at the highest risk for excessive dental care needs while at basic military training.

Dual use of cigarettes and smokeless tobacco among active duty service members in the US military.

The high prevalence of dual use of cigarettes and smokeless tobacco is a unique tobacco use behavior in the US military population. However, dual tobacco use has rarely been addressed in active duty populations. We aimed to identify factors contributing to dual tobacco use among active duty service members from Army and Air Force. We also compared age at initiation, duration of use, and amount of use between dual users and exclusive users. The study included 168 exclusive cigarette smokers, 171 exclusive smokeless tobacco users, and 110 dual users. In stepwise logistic regression, smokeless tobacco use among family members (OR = 4.78, 95% CI = 2.05-11.13 for father use vs. no use, OR = 3.39, 95% CI = 1.56-7.37 for other relatives use vs. no use), and deployment history (serving combat unit vs. combat support unit: OR = 4.12, 95% CI = 1.59-10.66; never deployed vs. combat support unit: OR = 3.32, 95% CI = 1.45-7.61) were factors identified to be associated with dual use relative to exclusive cigarette smoking. Cigarette smoking among family members (OR = 1.96, 95% CI = 1.07-3.60 for sibling smoking), high perception of harm using smokeless tobacco (OR = 2.34, 95% CI = 1.29-4.26), secondhand smoke exposure (OR = 4.83, 95% CI = 2.73-8.55), and lower education (associated degree or some college: OR = 2.76, 95% CI = 1.01-7.51; high school of lower: OR = 4.10, 95% CI = 1.45-11.61) were factors associated with dual use relative to exclusive smokeless tobacco use. Compared to exclusive cigarette smokers, dual users started smoking at younger age, smoked cigarettes for longer period, and smoked more cigarettes per day. Our study addressed dual tobacco use behavior in military population and has implications to tobacco control programs in the military.

Oral Health Status Among Adults With and Without Prior Active Duty Service in the U.S. Armed Forces, NHANES 2011-2014.

INTRODUCTION: Many veterans qualify for health benefits but generally not dental care. This study examines differences in oral health status between veterans and nonveterans in the U.S. to determine how various factors, including socioeconomic, general health, and tobacco use, impact former service members' oral health. MATERIALS AND METHODS: Data from 11,539 dentate adults participating in the National Health and Nutrition Examination Survey (2011-2014) were used. Outcome variables included decayed teeth (DT), missing teeth (MT), filled teeth (FT), caries experience (DMFT), and periodontitis (PD). Covariates included demographic and socioeconomic factors, deployment, smoking, depression, hypertension, hyperlipidemia, and diabetes. Logistic regression modelling was used to assess associations between these factors and oral health outcomes. RESULTS: Veterans represent about 9% of the U.S. population. There was a higher prevalence of PD, MT, FT, and DMFT among veterans than nonveterans. Veterans were more likely to have PD (OR, 1.8; 95% CI, 1.3 to 2.5) and higher DMFT (OR, 2.9; 95% CI, 2.4 to 3.4); however, after controlling for other covariates, military service was only associated with FT (OR, 1.3; 95% CI, 1.1 to 1.6) and higher DMFT (OR, 1.6; 95% CI, 1.2 to 1.9). CONCLUSIONS: Because veterans are more likely to originate from groups at a higher risk for poor oral health (older adults, smokers, males, diabetics), the prevalence of adverse oral health conditions are higher among veterans compared to nonveterans. Overall, military service is not associated with PD or untreated dental caries but is associated with indicators suggesting veterans have had more dental treatment (FT and DMFT). There is substantial unmet oral health care need primarily related to periodontitis among veterans.

Risk Indicators of Urgent and Extensive Dental Treatment Needs in U.S. Air Force Recruits.

INTRODUCTION: Dental Readiness Classifications (DRCs) enable the Military Health System to prioritize dental care in garrison, minimizing dental emergencies and mission degradation during deployments. Over half (52.4%) of 2008 military recruits presented with high-priority urgent needs classified as DRC3 upon initial dental examination and 18.1% required extensive treatment, needing 7 or more restorations, in order to achieve operational dental readiness. The purpose of this study is to identify risk indicators for urgent and extensive dental treatment needs in current U.S. Air Force (USAF) recruits so that Dental Corps leadership can target interventions to maximize oral health, prioritize resources, and reduce health expenditures in this patient population. MATERIALS AND METHODS: A secondary data analysis was performed of deidentified survey and clinical exam data from the 2018 to 2019 USAF Recruit Oral Health Surveillance study conducted at Lackland Air Force Base from February 2018 to February 2019. Select demographic and self-reported variables were analyzed with two outcome variables: urgent (DRC3) and urgent and extensive (DRC3 + 7) dental treatment needs. Univariate log binomial regression was performed to determine relative risk of DRC3 and DRC3 + 7 by independent variable. The Uniformed Services University of the Health Sciences institutional review board approved the study as an exempt protocol. RESULTS: Among the 1,335 recruits studied, the overall prevalence of urgent dental needs was 21.5%, whereas 5.5% of participants had both urgent and extensive needs. The study group included participants who were mostly male (69%), were non-Hispanic white (60%), aged 17 to 19 years (48%), were high school educated (47%), had private dental insurance coverage (50%) and self-reported: no need for dental care in the past year (65%), excellent or good condition of teeth (63%), were toothbrushing more than once a day (58%), and had daily consumption of one to three servings of sugary beverages (62%) and foods (69%). Statistically significant differences in relative risk for DRC3 were found for all independent variables except gender and education level. Risk indicators significant for DRC3 and DRC3 + 7 were aged 25 to 29 years; Other and Black race/ethnicity; Medicaid insurance; uninsured; self-reported fair, poor, or unsure current condition of teeth; and past year needed care but did not go (P < .05). The majority of DRC3 and DRC3 + 7 cases were in the small subset of recruits who self-reported fair, poor, or unknown current condition of teeth or need for dental care in the past year without a dental visit. CONCLUSIONS: Among USAF recruits, oral health disparities are observed in certain groups. The study findings can inform targeted utilization of resources and interventions to efficiently optimize oral health and operational dental readiness and decrease dental expenditures. Additionally, a two-question screening tool is proposed to facilitate priority assignment for dental examination during boot camp. This tool has the potential to correctly identify nearly 90% of those with urgent and extensive dental treatment needs at half the typical workload.

Dental Caries Risk in the U.S. Air Force: 2009 to 2017.

INTRODUCTION: The Air Force uses dental caries risk assessments (CRA) to determine which active duty Air Force (ADAF) members are at high caries risk (HCR) and will benefit from additional preventive and restorative dental care. The purpose of this study is to describe the caries risk of ADAF from 2009 to 2017 and determine how demographic, military, and tobacco-use characteristics affect caries risk. MATERIALS AND METHODS: Data from ~300,000 ADAF annual dental examinations from 2009 to 2017 were used. The outcome variable investigated was dental caries risk (high, moderate, or low). Independent variables analyzed were: age, sex, race, education, marital status, military rank, service years, flying status, and tobacco use. Descriptive and multivariable analyses were performed to explore associations between potential risk indicators and caries risk outcomes. RESULTS: From 2009 to 2013, there was a steady decline in ADAF that were diagnosed as low caries risk (LCR), from 80.3% to 67.7%. Since 2013, the prevalence of ADAF that are LCR has remained unchanged at about two-thirds of the force. The proportion of the ADAF that are moderate caries risk (MCR) increased from 15.7% in 2009 to 25.3% in 2013 and remained unchanged affecting about a quarter of the force since then. The proportion that was diagnosed as HCR increased from 3.9% in 2009 to 7.1% in 2013 and declined slightly in 2017 (6.0%). After controlling for other covariates, younger age (<20 years old: odds ratio [OR], 4.4; 95% confidence interval [CI], 3.3-5.8), less time in service (≤4 years: OR, 2.1; 95% CI, 1.7-2.6), junior rank (E-1-E-4: OR, 1.6; 95% CI, 1.3-1.8), less education (high-school graduate: OR, 2.3; 95% CI, 2.0-2.6), using tobacco (Smoker: OR, 1.6; 95% CI, 1.5-1.7), being a nonflyer (OR, 1.2; 95% CI, 1.1-1.3), being male (OR, 1.1; 95% CI, 1.1-1.2), or being black (OR, 1.2; 95% CI, 1.1-1.2) were each associated with being HCR. Among the cohort of Airmen who were LCR at baseline, the majority (75.9%) remained at low risk, but for nearly a quarter (24.1%), their risk of caries increased over 9 years. Among those who were originally MCR in 2009, 61.5% improved to LCR, whereas 4.6% progressed to HCR; among those identified as high risk for caries in 2009, a substantial majority (89.1%) improved over 9 years, but 10.9% remained unchanged. CONCLUSIONS: The prevalence of HCR and MCR service members increased from 2009 to 2013 but has remained consistent since 2013. Overall caries risk in the Air Force is lower compared to previously published findings from 2001 to 2004. This suggests that CRA and prevention programs have been effective at helping to reduce caries prevalence among Airmen. Smoking prevalence among ADAF has also declined substantially over the past 16 years which may contribute to overall caries risk reductions. Using a CRA approach may be an effective tool for helping to identify and develop strategies to manage dental caries risk in patients.

Electronic Cigarette Use and Related Factors among Active Duty Service Members in the U.S. Military.

INTRODUCTION: Electronic cigarettes (e-cigarettes) are increasingly used in the U.S.A. by young people. As young adults serve as the primary recruiting pool for military, active duty service members in military may be susceptible to using e-cigarettes. However, factors related to e-cigarette use in military population have rarely been studied. We aimed to identify factors associated with e-cigarette use and factors related to duration of use among active duty service members. MATERIALS AND METHODS: Subjects (N = 2,467) from Fort Bragg Army Base, North Carolina and Lackland Air Force Base, Texas completed a self-administered questionnaire during July 2015 to May 2016 time frame. The questionnaire collected data on demographic and military characteristics, tobacco use (including e-cigarette use) and other information. Stepwise logistic regression was performed to identify significant factors associated with e-cigarette use. Stepwise linear regression was performed to identify factors associated with duration of use. RESULTS: A total of 356 (14.4%) study participants reported ever use of e-cigarettes. There was no significant difference in prevalence of use between the two military installations (15.6% at Fort Bragg vs. 13.2% at Lackland, P = 0.097). Increased use of e-cigarettes was associated with young age (20-24 years old) (OR = 1.98, 95% CI = 1.22-3.22), enlisted military rank (E1-E4: OR = 2.45, 95% CI = 1.36-4.40; E5-E9: OR = 1.88, 95% CI = 1.10-3.21), low perception of harm (OR = 5.18, 95% CI = 3.65-7.34), former (OR = 9.12, 95% CI = 6.29-13.22) and current (OR = 13.24, 95% CI = 9.22-19.02) cigarette smoking, and former smokeless tobacco use (OR = 2.07, 95% CI = 1.33-3.22), former (OR = 2.62, 95% CI = 1.42-4.85) and current (OR = 2.82, 95% CI = 1.82-4.37) cigar or pipe smoking. However, serving mainly in combat unit during deployment was associated with decreased odds of use (OR = 0.57, 95% CI = 0.34-0.97). Among e-cigarette users, the number of years using e-cigarettes was significantly longer among the participants with lower perception of harm than those with higher perception of harm (0.82 vs. 0.22, P < 0.001), and the duration was longer among subjects who used e-cigarette with nicotine than those without nicotine (0.79 vs. 0.49, P = 0.003). Finally, reasons for use differed markedly by cigarette smoking status. Never smokers used e-cigarette for the taste or flavor, while cigarette smokers used e-cigarette to help quit tobacco or reduce tobacco use. CONCLUSION: Young age, lower military ranks, other tobacco use, and low perception of harm were associated with increased odds of using e-cigarettes, while serving in combat unit was associated with decreased odds of use in active duty service members. Low harm perception and using nicotine-containing e-cigarettes were associated with long duration of use. The reasons for using e-cigarettes differed by cigarette smoking status. Our study provides clues for future hypothesis-driven studies.

Determinants of receiving intravenous sedation in a sample of dentally-fearful patients in the USA.

Dental fear may be the most common reason for referral for intravenous sedation. Intravenous sedation offers many patients an opportunity to obtain needed dental care. However, intravenous sedation also has costs and may not help patients overcome their fear. Given a sample of 518 dentally-fearful patients in the USA presenting for dental care, this study examined the variables which predicted receiving intravenous sedation or not. About one-fifth of the patients received intravenous sedation, while the others received only cognitive behavioural therapy. Having more carious teeth, higher dental fear, more negative beliefs about dentists, lifetime diagnoses of panic disorder and/or generalized anxiety disorder, fewer existing coping skills, and a lower desire to cope with the dental situation were each predictive of having intravenous sedation. When the variables were considered simultaneously, only lower desire to cope contributed uniquely to the prediction. In a setting where psychological treatment for dental fear is available, patients' desire to cope with their fear was the most important factor in determining whether they received intravenous sedation or not.
