The use of locally delivered antibiotic together with the bone graft may reduce the undesirable effects related to the systemic administration and the risk of resistances. In the light of the results obtained, these grafting materials might offer new treatment strategies in the surgical regenerative treatment of peri-implantitis.
Knowledge of factors related to the use of preventive practices is essential in order to build strategies to decrease cancer incidence and mortality. The aim of this study is to describe the characteristics of women who periodically use cervical smear and mammography. This is a cross-sectional study based on the 2001 Balearic Health Survey, using a stratified sample of non-institutionalized population resident in the Balearic Islands. The study included 560 women, aged 20 years or over. The variables studied were age, marital status, social class, education, place of residence and birth, self-perceived health status, satisfaction with health services, job status and type of medical coverage. A multivariate analysis was performed using logistic regression models. Thirty-five per cent had regular mammography (72% between 50 and 64 years) and 54% had cervical smears. The probability of having undergone mammography is higher in women between the ages of 50 and 64 years [odds ratio (OR)=11.74; interval confidence (IC): 5.89-23.39] and in those with additional medical coverage (OR=1.97; IC: 1.19-3.27) and much lower in single women (OR=0.22; IC: 0.10-0.49). The probability of having undergone a Pap test increases according to educational level (OR=2.25; IC: 0.98-5.18 for women in the higher level) and social class (OR=1.98; IC: 0.91-4.28 for social class I) and decreases in women older than 65 years (OR=0.15; IC: 0.07-0.35) and in single women (OR=0.29; IC: 0.16-0.50). Age and marital status are factors related to both practices. Socio-economic status remains associated with cervical smear use, while having an additional medical coverage increases the probability of regular mammography.
Objective
To compare clinical efficacy, chairside time and post‐treatment hypersensitivity of four instruments used for subgingival periodontal debridement.
Materials & Methods
Seventeen patients with stage II and III periodontitis were enrolled in this randomized clinical trial using a split‐mouth design. Quadrants were randomly divided into four treatment groups: Group A: Gracey curettes‐Hu‐Friedy®; Group B: piezoelectric ultrasonic (Satelec®) with No.1S insert; Group C: diamond burs 40 µm (Intensiv Perioset®); and Group D: piezosurgery ultrasonic (Mectron®) with PP1 insert. Clinical outcomes, chairside time and hypersensitivity were assessed at 1, 2, 4 and 8 weeks after treatment. The primary outcome variable was improvement in clinical attachment level.
Results
At 8 weeks post‐treatment, Gracey curettes, piezoelectric ultrasonic (Satelec®) and piezosurgery ultrasonic (Mectron®) were statistically more effective than diamond burs in increasing attachment level and reducing probing pocket depth. Comparison of piezoelectric ultrasonic (Satelec®) and piezosurgery ultrasonic (Mectron®) with the other instruments showed a statistical difference (p < 0.001) in chairside time. Regarding post‐treatment hypersensitivity, no statistical differences were observed in any of the groups.
Conclusions
Gracey curettes, piezoelectric ultrasonic (Satelec®) and piezosurgery ultrasonic (Mectron®) were clinically more effective than diamond burs 40 µm. The ultrasonic instruments showed a significant reduction in chairside time.
Landscape plays a vital role in the development of military campaigns through the definition of geostrategic landmarks that structure the control of the territory, the imposition of constraints to the movement of armies, and the identification of positions that facilitate defensive tactics against aggressors. These factors are linked to the study of past spatial mobility which is typically performed using Least-Cost Path analysis (LCP). LCP identifies the optimal route that connects any two given points based on minimizing the accumulated cost based on a friction surface map, thus allowing archaeologists to identify the most efficient pathways across a territory. The main challenge of LCP analysis for archaeological regions is that optimal pathways are not well suited to define general mobility patterns within highly uncertain scenarios. Connectivity modelling based on Circuit Theory (CT) is an alternative approach to the study of mobility. CT does not generate a single path like LCP does; it captures the connectivity of an entire region identifying not only optimal paths, but also bottlenecks, dead-ends and any other spatial feature that may impact movement.We present here a framework to study landscapes of conflict using connectivity modelling; the framework combines CT, visibility analysis and statistical hypothesis testing to understand the reasons behind the assault and destruction of Puig Ciutat (NE Iberian Peninsula) during Julius Caesar's civil war. Results suggest that the site exerted decisive control over a highly connected area linking two possible logistical bases (Emporion and Massalia) to the armies fighting at Ilerda (49 BC).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
