AbstractThis study aimed to noninvasively assess the relationship between the labial gingival thickness (GT) and the underlying bone thickness (BT) of maxillary anterior teeth by two digital techniques. A total of 30 periodontally healthy participants with 172 maxillary anterior teeth were enrolled. GT and BT were measured at 2, 4 and 6 mm apical to the cemento-enamel junction (CEJ) by two digital techniques: M1—cone-beam computed tomography (CBCT) and M2—digital intraoral scanning (DIS) combined with CBCT. The Pearson's correlation coefficient was calculated to determine the correlation between GT and BT. A significant negative correlation was identified between GT and BT at 2 mm apical to the CEJ for central incisors (CI), lateral incisors (LI), and canines (CA) both by M1 and M2, while a weak negative correlation at 4 mm apical to the CEJ was observed by M1 for CA. No significant correlation was found at other sites by both M1 and M2. The labial BT was < 1 mm in most cases (85% of CI; 97% of LI; and 90% of CA). Within the limitation of this study, it was concluded that GT and BT seemed to be negatively correlated at 2 mm apical to the CEJ. Therefore, caution is warranted when implant restoration at the esthetic area of the anterior teeth.

Abstract The aim of this study is to noninvasively assess the relationship between the labial gingival thickness (GT) and the underlying bone thickness (BT) of the maxillary anterior teeth by two digital techniques. GT and BT were measured at 2、4 and 6 mm apical to the cemento-enamel junction (CEJ) by two digital techniques: M1- cone-beam computed tomography (CBCT) and M2- digital intraoral scanning (DIS) combined with CBCT (30 healthy participants, 172 maxillary anterior teeth). Pearson's correlation coefficient was calculated to assess the correlation between GT and BT. A significant negative correlation was identified between GT and BT at 2、4 mm apical to the CEJ for central incisors (CI), lateral incisors (LI), and canines (CA) both by M1 and M2, but not at 4 mm apical to the CEJ for CA (M2) or at 6 mm apical to the CEJ for all (M1, M2). The labial BT was demonstrated < 1 mm in most cases (85% of the CI; 97% of the LI; and 90% of the CA). Within the limitation of this study, it is concluded that the GT and BT seems to be negatively correlated in most cases, which should be cautious clinically.

Insomnia Severity

Abstract Introduction Bedtime Procrastination (BP) is defined as the behavior of going to bed later than intended, despite the absence of external factors. Bedtime procrastination is also prevalent among insomnia patients, and is associated with various sleep problems. Recent studies suggest emotional regulation as a mechanism of the procrastination behavior that is the conceptual foundation of bedtime procrastination. Emotional regulation difficulties are also associated with insomnia, but there is still a lack of research on the relationship between insomnia, emotional regulation strategies and bedtime procrastination. Thus, the study assumed that severity of insomnia would affect bedtime procrastination, and examined the moderating effect of the emotional regulation strategies in this relationship. Methods This study was conducted in 376 adults (mean age 23.73 ±2.14 years, 84.6% females). Participants were asked to answer Bedtime procrastination scale (BPS), an emotional regulation strategy checklist, and the Insomnia severity scale (ISI). Results As a result, a significant positive correlation was found between insomnia severity and bedtime procrastination (r=.286, p&lt;.01), and avoidant/distractive regulation style (r=.101, p&lt;.05). active regulation style (r=-.172, p&lt;.01) and support seeking regulation style (r=-.102, p&lt;.01) showed a significant negative correlation with the severity of insomnia. Bedtime procrastination behavior showed significant negative correlation only with active regulation style (r=-.151, p&lt;.01). Support seeking regulation style moderated the relationship between insomnia and bedtime procrastination behavior (B=.0165, 95%, CI=.0014, .0316). The interaction effect between insomnia and support seeking regulation style was also significant (∆R^2=.0112, p&lt;.05), indicating that the effect of insomnia on bedtime procrastination depends on the level of use of the support seeking regulation style. Conclusion These findings suggest that the level of support seeking regulation style is meaningful in terms of how insomnia affects bedtime procrastination.

Abstract Background Knowledge of gingival thickness (GT) and alveolar crest thickness (ACT) is essential when performing surgical and non-surgical procedures in the maxillary anterior teeth region. This study aimed at evaluating the GT and ACT in the maxillary anterior teeth region using 15-MHz B-mode Ultrasonic (US). Methods A total of 300 teeth from 50 healthy participants, comprising 25 women and 25 men, aged between 18 and 35 years were analyzed. We measured labial periodontal tissue structures of maxillary anterior teeth, including GT and ACT, at 3 mm apical to the gingival margin (GT3) and the crestal level, respectively. The GT and ACT measurements were correlated. Results The mean labial GT3 of the maxillary central incisors, lateral incisors, and canines were 1.24 ± 0.03 mm, 1.21 ± 0.03 mm and 1.11 ± 0.03 mm, respectively. Canine GT3 was significantly thin than those in the central and lateral incisors (P < 0.05). With regards to labial ACT, we recorded 0.79 ± 0.03 mm, 0.76 ± 0.02 mm and 0.73 ± 0.02 mm for maxillary central incisors, lateral incisors and canines, respectively. There were no significant differences in ACT of maxillary anterior teeth (P > 0.05). GT3 of men was greater than that of women (P < 0.05). In addition, GT and ACT were positively correlated (r = 0.32, P < 0.01). Conclusion 15-MHz B-mode US is an effective tool for measuring labial GT and ACT of anterior teeth. There are sex-associated differences in GT3 and the correlation between the GT3 and ACT of anterior teeth is moderately positive.

Logotherapy, developed by Viktor Frankl, posits that when one lacks meaning in life, boredom can result. Thus, the two constructs should be inversely related. To examine this relationship, 279 students ( M = 19.8 yr., SD = 2.6; 179 women, 98 men) from a university in the southern United States were administered the Purpose of Life test and the Boredom Proneness Scale. As expected, a statistically significant negative correlation was found between the scores on the two scales ( r = -.71). Directions for research are offered.

Purpose – The purpose of this paper is to examine securities analyst independence in China's capital market and the effect on analyst independence of institutional investors’ shareholding and separation between control rights and cash flow rights of ultimate controller. Design/methodology/approach – Using data of China's listed companies from 2006 to 2012, the authors empirically tested the relationship between analyst following and volatility of stock return. And based on the test, the authors investigated the role played by institutional investors’ ownership and separation between control rights and cash flow rights of ultimate controller. Findings – According to the empirical results, there is a significant negative correlation between analyst following and volatility of stock return. Also, shareholding of institutional investors and the separation between control rights and cash flow rights of ultimate controllers will have an impact on the relationship between analyst following and volatility of stock return. When institutional investors hold higher proportion or the separation between control rights and cash flow rights of ultimate controllers keeps at a high level, the negative correlation between analyst following and volatility of stock return will weaken. Originality/value – First, based on the theory of market intermediation, the paper examined analyst independence by investigating and analyzing the relationship between analyst following and volatility of stock return. Second, it analyzed the factors affecting analyst independence by integrating enterprise characteristic variable and market characteristic variable on the basis of introducing two variables – shareholding of institutional investors and the separation between control rights and cash flow rights of ultimate controllers.

The Relationship

1. The relationship between baroreflex sensitivity (BRS) and arterial compliance index (ACI) has been investigated (a) in paired subjects matched in one instance for systolic blood pressure with differing ages, and (b) in another instance matched for age with differing systolic blood pressures. 2. There was a significant negative correlation between BRS and age and between ACI and age in the twelve systolic blood pressure-matched subjects. 3. A significant negative correlation of systolic blood pressure with both BRS and ACI was observed in the fourteen age-matched subjects. 4. Both BRS and ACI appear to decrease with increasing age and systolic blood pressure. This decrease in BRS is probably due at least in part to the observed reduction in arterial distensibility.
