The need for dental treatments, especially those related to dental caries, may be associated with and influenced by a wide range of demographic variables. The aim of this study was to describe caries related treatment needs among young Israeli adults and the association with several socio-demographic factors, including socio-economic cluster (SEC), intellectual capabilities, ethnicity and other variables. Data were collected from dental records of army recruits between 2012 and 2013. We cross-examined data regarding dental treatment needs with socio-demographic variables: age, gender, SEC, intellectual capability score (ICS), birth place of participant and parents, education and immigration. Data received regarding 13,398 combat recruits during their first four months of military training. Most subjects were males (92.4%), with a mean age of 18.9 years. 10.8% were immigrants, with 12.2 years living in Israel before their recruitment. Only 17.7% had no dental treatment needs. Mean number of teeth needing treatment was: for restorations 1.96 ± 2.59, for root canal therapies 0.07 ± 0.44 and for extractions 0.05 ± 0.28. Low ICS scores and low SEC group were significantly associated with higher treatment needs (P < 0.001). Statistically significant higher treatment needs were observed among participants who originated from immigrant families. In a multivariate analysis (Generalized Linear Model), gender, age, ICS score, SEC group and country of birth were found as independent predictors for number of restorations needed. Socio-demographic variables significantly influence dental treatment needs and should be taken into account when preparing intervention programs in this population.

“SOS teeth” are defined as the first priority teeth for treatment, that have distinct cavitation reaching the pulp chamber or only root fragments are present. These are teeth with severe morbidity, that may require pulp capping, root canal treatment, or extraction, and therefore should be treated first. The study aims to explore whether or not a metabolic syndrome (MetS) is associated with SOS teeth. To that end, we performed across-sectional records-based study of a nationally representative sample of 132,529 military personnel aged 18–50 years, who attended the military dental clinics for one year. The mean number of SOS had no statistically significant association with: smoking (p = 0.858), alcohol consumption (p = 0.878), hypertension (p = 0.429), diabetes mellitus (p = 0.866), impaired glucose tolerance (p = 0.909), hyperlipidemia (p = 0.246), ischemic heart disease (p = 0.694), S/P myocardial infarction (p = 0.957), obstructive sleep apnea (p = 0.395), fatty liver (p = 0.074), S/P stroke (p = 0.589), and S/P transient ischemic attack (p = 0.095) and with parental history of: diabetes (p = 0.396)], cardiovascular disease (p = 0.360), stroke (p = 0.368), and sudden death (p = 0.063) as well as with any of the medical auxiliary examinations (p > 0.05). Cariogenic diet was positively associated with SOS teeth (p < 0.001). We conclude that SOS teeth had no statistically significant association with MetS components or with conditions that are consequences or associated with MetS. The only statistically significant parameter was a cariogenic diet, a well-known risk factor for caries and MetS.

This study aimed to examine the relationships between dissociative and somatic symptoms and how they might contribute to PTSD severity among ex-soldiers who sought help from the IDF Combat Stress Reaction Unit (CSRU). This cross-sectional study included 1,305 former compulsory, career, and reserve soldiers, who filled out self-report questionnaires on admission for evaluation at the CSRU. The study’s dependent variables included two posttraumatic stress disorder measures (CAPS and PCL-5). The independent variables were the Dissociative Experience Scale and Brief Symptom Inventory. Background and service-related variables were also examined. Spearman correlation revealed that the higher the level of somatization is, the higher the level of PTSD via PCL and CAPS. A significant positive association was found between somatization and dissociation (r = 0.544; P < 0.001). The higher the somatization level, the more severe the dissociation. A multivariate logistic regression analysis to predict severe PTSD revealed that the longer the time elapsed from the traumatic event (OR = 1.019, P = 0.015), the higher the risk for severe PTSD. The most prominent variables were dissociation (OR = 6.420, P < 0.001) and somatization (OR = 4.792, P < 0.001). The entire model reached 40.8% of the shared variance in the regression. While there is direct reference to dissociation in the clinical assessment by PCL or CAPS, there is no such reference to somatization. Highly functioning combatants sometimes express their distress somatically. Our findings suggest regarding severe somatic symptoms as diagnostic criteria for PTSD.

The exposure to war scenes via screens, despite offering a degree of detachment, can be stressful for the operator. The aim of the current study is to examine the existence of anxiety, depression, and post traumatic stress disorder (PTSD) symptoms among unmanned aerial vehicle (UAV) Israeli operators. Participants comprised 41 UAV operators (87.2% male), aged 22–38 (M age = 26.05, SD = 3.54). Most (78.0%) reported having viewed battlefield scenes. All participants completed a total of five questionnaires: Beck Depression Inventory, State-Trait Anxiety Inventory, and three questionnaires of PTSD: Post Trauma Questionnaire (CAPS), the Post-Traumatic Cognition Inventory (CTPI), and the Post-Traumatic Symptom Scale (PSS). Mean scores of depression and anxiety were found significantly lower than diagnosis cut-off points (p < .001). Senior operators showed higher means for depression (5.69 vs. 2.58, p = .040), of stress level (PSS; 3.17 vs. 0.25, p = .020) and for distress intensity (3.79 vs. 0.57, p = 0.041) than less-experienced operators. Investigating and monitoring the impact of battlefield exposure in UAV operators are highly beneficial for preventing psychopathology.

Background: “SOS teeth” are defined as the first priority teeth for treatment, that have distinct cavitation reaching the pulp chamber or only root fragments are present. Objectives: To assess the prevalence and distribution of SOS teeth with regard to age and sex difference among young to middle-aged adults. Methods: This is a cross-sectional records-based study of a nationally representative sample, consisting of young to middle-aged military personnel, who attended the military dental clinics of the Israel Defense Forces (IDF) for one year. SOS teeth definition corresponds to code number 6 of the “Caries Assessment Spectrum and Treatment (CAST)” as an instrument to assess dental caries. Data pertaining to age and sex were drawn from the central demographic database and that of SOS teeth were obtained from the Dental Patient Record (DPR). Results: The study included 132,529 dental records. The prevalence of patients with SOS teeth was 9.18 % (12,146/132,323). The number of teeth that were found to be SOS teeth was 18,300, i.e., 1.5 SOS teeth per “diseased” patient (18,300/12,146). The mean number of SOS teeth per the whole study population was 0.14 ± 0.52 and the range was 0–20. The mean number of SOS teeth per patient had a statistically significant negative correlation with age (p < 0.001; Odds Ratio (OR) = 0.997; 95% confidence interval: 0.997–0.998) and with male sex compared to females (p < 0.001; OR = 1.029 confidence interval: 1.023–1.036). Conclusion: Assessment of first priority SOS teeth may be part of the dentist’s work-up. It provides dentists and health authorities with useful information regarding urgent dental care needs to plan dental services.
