Noninvasive and inexpensive methods of isolating and characterization of biomarkers from cellular and extracellular skeletal matrix during bone regeneration have proven value in evaluating success of bone biomaterials.
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.
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.
