Aim and Objectives:Oral surgical procedures can cause spread of infections in the clinics through visually imperceptible, splattered, and aerosolized blood. The aim of this study was to evaluate visually imperceptible blood contamination of clinical surfaces and personal protective equipment (PPE) in an oral surgery clinic using luminol.Materials and Methods:Following ethical approval, oral surgical procedures were performed under local anesthesia in a disinfected clinic, and PPE was used by the oral surgeon, dental assistant, and patients. After the procedure, clinical surfaces and PPE were evaluated for traces of visually imperceptible blood contamination using luminol. Data regarding blood contamination and the duration of the procedure were collected. Nonparametric tests, with 95% significance level (Epi Info, Stat Calc 7, CDC, Atlanta, USA), were used to identify statistical interactions between the duration of the procedure and the frequency of blood contamination.Results:Blood contamination was detected in flooring below surgical field (86.67%), instrument tray, operating light, dental chair, and suction unit (100%). Except head caps and shoe covers, blood contamination was detected in all the PPE used by the clinical personnel, and the eyewear and chest drapes used by patients. An increase in the surgical time beyond 40 min significantly increased the risk of blood contamination in the handcuffs of the clinical personnel (P < 0.01).Discussion and Conclusion:Visually imperceptible blood contamination of the clinical surfaces and PPE is associated with minor oral surgical procedures. This mandates the cleaning and disinfection of all clinical surfaces before and after minor oral surgical procedures and PPE for clinicians and patients during every procedure.

BACKGROUND AND AIM:Increasing incidence of medically compromised patients seeking dental treatment and implant rehabilitation, necessitates greater knowledge toward managing such patients. The objective of the present study was to evaluate the perceptions of dental interns in Riyadh, Saudi Arabia, toward dental implant therapy for medically compromised patients.MATERIALS AND METHODS:Using a convenience random sampling technique, a cross-sectional questionnaire-based study was conducted to evaluate the perceptions of the interns from dental schools in Riyadh, Saudi Arabia. Data pertaining to demographic details of the participants, academic grade point average (GPA), clinical implant training and experience and perceptions about dental implant therapy for medically compromised patients were collected.RESULTS:The survey response rate was 82.9% (n = 174/210; Males-129/Females-45). Less than half of the interns (n = 82/174; 47.1%) had performed dental implants, out of which 41.5% (n = 34/82) had placed implants in medically compromised patients. Most medical illnesses except controlled diabetes mellitus and hypertension were perceived by the interns as contraindications for dental implant placement.CONCLUSION:Based on the results of the present study, it could be concluded that courses with a greater emphasis toward management of dental patients with medical problems and undergraduate implant training for such patients would result in better knowledge and perception among dental interns regarding dental implant placement in medically compromised patients.

The objective of this study was to evaluate the potential of reusing domestic rinse water in an indoor hydroponic system and compare the growth pattern of Coleus plants using tap water and rinse water. A preliminary survey evaluatedthe knowledge about, home gardening, hydroponics, water usage and utility of rinse water in urban households. The experimental setup consisted of water culture hydroponic system with peat moss media. Data were collected and analyzed from 4 sample groups: Group A (tap water), B (tap water with NPK fertilizer), C (rinse water) and D (rinse water with NPK fertilizer) in a randomized experimental design (N=20) with five replicates.The study was conducted indoors in an urban household under controlled temperature (78ºF), light and humidity (60-70%). Parameters analyzed for assessment of plants growth included height (in millimeters), number of new leaves and leaf surface area. Environmental parameters including, pH and TDS (Total Dissolved Solids in parts per million) of the hydroponic solution, and pH and moisture of soil were also recorded. Descriptive statistical analysis and independent comparisons were done with a 95% assumed significance level (p<0.05).During the 20th, 25th and 30th day, plant height in Group A was significantly (p<0.05) higher than that of Group B and plant height in Group C was significantly higher than in Groups B and D.In terms of the environmental parameters, while rinse water had an alkaline pH, the addition of NPK fertilizer (Groups B and D) resulted in significantly lower pH.Based on the present study results, domestic rinse water can be reused as a successful alternative for tap water in indoor hydroponic cultivation of plants without the need for any additional fertilizer.
