Evaluation of an oral health programme targeting prison inmates in Saudi Arabia.

This paper aimed to evaluate the impact of an oral health programme targeting prisoners in eastern Saudi Arabia. The reach, effectiveness, adoption, implementation and maintenance (RE-AIM) strategy was used as the evaluation framework to assess both process and outcome. This annual programme included four stations: an interview, an educational session, dental examination and treatment. Programme indicators included the number of prisoners reached, percent improvement in oral health practices, teeth present in the mouth and percent reduction in dental treatment needs. A non-experimental pre- and post-programme evaluation design was implemented. Prisons in eastern Saudi Arabia were visited once a year from 2016 to 2019. The evaluation used primary data collected during the visits in the form of clinical examination and surveys. The number of beneficiaries increased from 270 to 634, and three cities within the Eastern province were covered. The percent of inmates who smoke and consume sugary drinks decreased by 24 and 30%, respectively; however, there was a 25% reduction in regular toothbrushing using a fluoridated toothpaste. The long-term outcomes showed an improvement in the overall oral health condition and treatment needs: periodontal treatment needs and surgical procedures were reduced by 91 and 79%, respectively. The programme was successful based on the RE-AIM framework. This is the first sustainable oral health programme targeting prison inmates in the Middle East. The findings indicate that the oral health programme had positive effects on prisoners' oral health and achieved its objectives. Such programmes can help address health disparities among populations.

The post-pandemic era: will physical distancing be a perceived way of life?

Background: This study aimed to determine whether people living in the Eastern Region of Saudi Arabia would prefer to continue the practice of physical distancing after the coronavirus disease 2019 (COVID-19) pandemic or to return to their previous way of life. Methods: This cross-sectional study was conducted from August 2020 to October 2020 in the Eastern Region of Saudi Arabia. A pre-tested questionnaire was sent electronically through social media. Data on participants' demographics and their perspectives regarding post-pandemic physical distancing were collected. The calculated sample size was 1,066; however, the total number of responses included in the analysis was 989. Results: The average age of the participants was 31.15±11.93 years. There were 435 men and 554 women in the study. Participants showed significantly high levels of disagreement with statements indicating that they were willing to use public transportation (61%), attend social gatherings (36%), and hug relatives or colleagues (40%) after the pandemic ( p<0.001); however, 43% agreed that they would spend time with family or friends ( p<0.001). The level of education was also found to be significantly related to the responses, and the level of disagreement increased as the level of education increased ( p<0.001). Conclusions: One-third of the study participants planned to continue engaging in physical distancing even after the current pandemic. This clearly indicates that our lives are not returning to how they were before the pandemic. However, it cannot be concluded whether or not this behavior will prevail in the long run. If so, it may greatly affect some businesses and perhaps some social norms and values as well.

The Effect of Er,Cr:YSGG and Diode Laser Applications on Dental Implant Surfaces Contaminated with Acinetobacter Baumannii and Pseudomonas Aeruginosa.

Treatment of peri-implantitis through several implant surface decontamination techniques have been reported, however, some of them can negatively alter the implant surface or enhance more bacterial resistance. The aim of this in vitro study was to evaluate implant surface decontamination by means of Er,Cr:YSGG and diode lasers. Fifty micro-textured (MTX) dental implants were contaminated with Acinetobacter baumannii (n = 25) and with Pseudomonas aeruginosa (n = 25). All implants were then divided into five groups for the decontamination procedure. In group I (GI), decontamination was done with an Er,Cr:YSGG laser (2780 nm), while in group II (GII) decontamination was performed using photodynamic therapy (a 650 nm diode laser). In Group III (GIII) decontamination was performed with photodynamic therapy (an 808 nm diode laser), and in group IV (GIV) decontamination was performed with 0.12% chlorhexidine. Group V (GV) was the control group with no decontamination. After decontamination, colony forming units (CFU) were counted and implants were prepared for SEM analysis. A significant difference (p < 0.001) was observed for GI compared to the other groups, and also for GIV compared to both GII and GIII. The Er,Cr:YSGG laser (GI) showed the best results in decontaminating the implant surface. Chlorhexidine (GIV), proved to be better in decontaminating the implant surface than photodynamic therapy GII and diode laser GIII. No significant difference was found between group GII and GIII. The SEM analysis showed no significant change in the implant surface topography. The results of this study suggest that the Er,Cr:YSGG laser can be considered as an effective technique for reducing bacteria contamination on implant surfaces.
