Family Influences on the Dental Caries Status of Children with Special Health Care Needs: A Systematic Review

The Impact of Military Tobacco Control Policy: A Systematic Review

INTRODUCTION

Tobacco use is synonymous with the military. Despite that military personnel are trained to follow commands, opportunities exist to implement various tobacco control strategies. We conducted a systematic review to evaluate the impact of tobacco control policy employed in military settings.

MATERIALS AND METHODS

We searched for published English articles in Medline, Web of Science, Scopus, and Google Scholar databases using relevant subject headings without year restriction. We included randomized controlled trials, nonrandomized controlled trials, case-control, cohort, controlled before and after, and uncontrolled before and after studies evaluating the impact of tobacco control policy in the military population. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, three independent reviewers independently screened initially identified articles, reviewed the full text, and extracted the data and any disagreements resolved by consensus after data recheck. Five reviewers used a validated tool to assess the quality of the included studies. The primary outcome was the reduction of any tobacco or nicotine-contained products (TNCPs) use among the troops. The impacts of the tobacco control policy were synthesized and analyzed qualitatively. This study is registered with the International Prospective Register of Systematic Review (CRD42022314117).

RESULTS

Fourteen studies were included in the analysis from 5372 studies screened. Most of the studies were from the USA, and fractions were from Thailand, France, and Taiwan. These studies were methodologically heterogeneous. Most studies employed a total ban policy on TNCP use during basic military training or operational deployment as the primary strategy. Other methods utilized were the brief tobacco intervention, targeted treatment, support, and counseling provided through telephone or mailing systems, the adjunctive behavioral intervention, providing free nicotine gum, the "Pharsai clinic", active and regular smoking restriction, and interventions aimed at intrapersonal, interpersonal, and organizational levels. There is a moderate quality of evidence that the tobacco control policies effectively reduced the prevalence of TNCP use, increased the cessation rate, reduced the intake, and lowered the dependency. The adjunctive interventions provided after the total ban on TNCP use may increase its effectiveness. However, findings from this review need to be carefully considered as the definition of TNCP use status was not universal between studies and lacked a biochemical validation procedure.

CONCLUSIONS

There is reasonable evidence to support that the tobacco control policy employed in the military population has multiple positive impacts in reducing the prevalence of TNCP use, increasing the cessation rates, reducing the intake, and lowering dependency. Other evidence-based strategies need to be fully utilized to materialize the tobacco endgame.

An Assessment of the Prevalence of Dental Caries, Oral Hygiene Status, Deft Index, and Oral Hygiene Habits Among Children With Special Healthcare Needs

Background and objective Children with special healthcare needs are at an increased risk of oral health problems, including dental caries. Understanding the prevalence of dental caries, oral hygiene status, deft (decayed, extracted, filled teeth) index, and oral hygiene habits in this population is crucial for effective oral healthcare planning and interventions. The aim of this study was to assess the prevalence of dental caries, oral hygiene status, deft index, and oral hygiene habits among children aged 4-15 years with special healthcare needs in Jodhpur District, Rajasthan, India. Methods A cross-sectional study was conducted among 124 children from various, government and non-governmental organizations (NGO)-run special schools. Data on dental caries, oral hygiene status, deft index, and oral hygiene habits were collected using standardized tools and techniques. Descriptive statistics, including frequencies and percentages, were used to analyze the data. Results The prevalence of dental caries among children with special healthcare needs was 65%. The severity of dental caries varied, with 40% classified as mild, 20% as moderate, and 5% as severe. Additionally, 75% of the children exhibited poor oral hygiene, as indicated by the oral hygiene status assessment. The mean deft index score was 2.8, indicating an average dental caries experience among the participants. Regarding oral hygiene habits, 60% reported brushing their teeth once a day, while 40% reported brushing twice a day. However, a significant proportion (70%) reported non-fluoride use, and 55% stated they did not perform regular flossing. Conclusion This study highlights a high prevalence of dental caries, poor oral hygiene status, and suboptimal oral hygiene habits among children with special healthcare needs in Jodhpur District. The findings emphasize the need for targeted interventions focusing on preventive measures, oral health education, and improving access to oral healthcare for this vulnerable population. Further research with larger sample sizes and longitudinal study designs is warranted to validate these findings and develop effective strategies for enhancing oral health outcomes in children with special healthcare needs.

Prevalence of Oral Pathogen Slackia exigua among Clinical Orthodontic and Non-Orthodontic Saliva Samples

Slackia exigua (SE) is a recently identified intestinal microbe, which recent oral surveys suggest may be associated with oral diseases including caries and periodontal disease. Based upon the lack of information regarding this organism, the primary objective of this study was to determine the oral prevalence of this microbe and any potential associations with patient characteristics such as age, sex, or the presence of orthodontic appliances. This retrospective study involved the screening of an existing saliva repository composed of previously collected unstimulated clinical saliva samples. More specifically, N = 266 were identified and screened using a spectrophotometer at absorbances of A260 and A280 nm to determine their DNA purity and concentration. qPCR screening of these samples revealed a higher prevalence of Slackia exigua positive samples among pediatric patients (63.1%) compared with adults (36.9%) in this clinic population, p = 0.0007. In addition, higher percentages of Slackia exigua were observed among orthodontic patients (71.2%) compared with non-orthodontic patients (28.8%), p = 0.0001. These results did not vary by sex with nearly equal percentages of Slackia exigua positive males and females among adult and pediatric patients, as well as orthodontic and non-orthodontic samples. These results suggest a strong potential for association between the prevalence of this organism with age as well as orthodontic status, given that younger patients and those with orthodontic brackets (regardless of age) were most likely to harbor this pathogen in sufficient levels to be detected in saliva. More research will be needed to determine any associations with specific outcomes, such as caries or periodontal disease, among Slackia exigua positive patients within these specific populations.
