Awareness, attitude, and practice of regenerative endodontic procedures among clinicians from different dental specialties
(2020) Jamal, Mohamed; Khawaja, Summayah
Introduction: This study assessed the opinions on and practice of regenerative endodontic procedures(REPs) among clinicians from different dental specialties. Materials and Methods: After the Institutional Review Board approval, 205 clinicians participated in a web-based survey and were asked about their educational level, professional status, opinion toward REPs, and preferred technique when performing REPs. Results: Although approximately 65% of participants were unsure or did not believe that there is enough evidence to support REPs, 78.2% believed that REPs are a better treatment option than apexification and 70.5% that they could be a future alternative to osseointegrated implants. The results also revealed variability in the preferred techniques to perform REPs, with 40.4% preferring the use of a mixture of antibiotics to disinfect the root canal space, whereas 20.2% preferred calcium hydroxide. Almost 66% were using ≥1 mg/mL of each antibiotic in the mixture, whereas 44.6% were using 0.1 mg/mL. Approximately 40% of participants used techniques that differ from the American Association of Endodontists’ clinical considerations for REPs. Interestingly, attending a continuing dental education course (CDE) significantly reduced the participants’ uncertainty toward REPs and increased their willingness to perform it themselves (P < 0.001). Conclusions: This survey revealed a positive attitude toward and general acceptance of REPs by dentists. It also showed considerable variability in techniques used to perform REPs. Conducting more CDE may increase the awareness of REPs among different dental specialties and reducing variability in techniques.

Abstract: Our study aimed to describe the root and canal morphology of mandibular second molars in Emirati population and to study the prevalence and types of morphological change in C-shaped canal confguration along the root length in an efort to describe C-shaped molars as a unit. Cone beam computed tomography (CBCT) scans of Emirati patients were analyzed in multiple plans and root and canal confguration of mandibular second molars were evaluated. Moreover, specifc types of morphological change in C-shaped canal confguration along root length were studied and reconstructed using 3D reconstruction software. A total of 508 mandibular second molars were evaluated. Among the non-C-shaped mandibular second molars, two separate roots were the most prevalent root morphology (78.3%). The mesial root’s most common root canal confguration was Vertucci Type II (46.5%), and in the distal root, Vertucci Type I (90.5%). The prevalence of C-shaped mandibular second molars was 17.9% and was signifcantly prevalent (P< 0.001) in females. Specifc types of morphological change in C-shaped molars along the root length were observed and described for the frst time, in which the most common types of morphological change were C1-C2-C3d (18%), C1-C3c-C3d (15.4%), C4-C3c-C3d (7.7%), and C3c-C3c-C3d (7.7%). This study showed wide variations in the root and canal morphology in mandibular second molars in Emirati population with a relatively high prevalence of C-shaped canal confguration (17.9%). Moreover, specifc types of morphological change in C-shaped confguration were detected and described for the frst time in this population.
Overview of transnational recommendations for COVID-19 transmission control in dental care settings
(2020) Jamal, Mohamed; Shah, Maanas; Khawaja, Summayah; El Abed, Rashid
Abstract: On 11 March 2020, the World Health Organization (WHO) declared the coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus (SARS-CoV-2) as a pandemic. Until an effective treatment or a vaccine is developed, the current recommendations are to contain the disease, and control its transmission. It is now clear that the primary mode of SARS-CoV-2 transmission is aerosol/droplet spread, and by contacting virus-contaminated surfaces acting as fomites (inanimate vectors). Furthermore, recent data indicate that the live virus particles are present in saliva, and, more alarmingly, asymptomatic individuals may transmit the infection. By virtue of the nature of the practice of dentistry where intrinsically, a high volume of aerosols is produced, as well as the close proximity of dentists and patients during treatment, dentists and allied health staff are considered the highest risk health professional group for acquiring SARS-CoV-2 during patient management. Therefore, several organizations and specialty associations have proposed guidelines and recommendations for limiting the transmission of SARS-COV-2 from carriers to dentists and vice versa. This paper aims to provide a review of these guidelines, and concludes with a brief look at how the practice of dentistry may be impacted by COVID-19, in the post-pandemic era.
