RESUMEN
Across the globe, there have been reports which have shown that all the dental professionals and the field of dentistry to be more vulnerable to the coronavirus infection. Dentists in general are comparatively more prone to infections as they are more exposed to aerosols and droplets emerging out of the patient’s oral cavity. This scare of coronavirus has unmasked the crevices in the integration of the dental health care professionals in to the public health care sector of various countries. It has significantly sidelined the dental treatment approach towards the patients and for the dental team as well. At this point, it is very difficult to project and calculate the exact number of cases of Covid-19 carriers or infected who are being treated by dentists. Such a preliminary survey will give us an idea about the precautionary measures that can be taken or being taken in dental practice. The aim of the study was to assess the knowledge, attitude and practice amongst dental professionals of different specialties about the Covid-19 and precautionary measures at different levels. METHODSAn online questionnaire based survey was carried out to assess the knowledge, attitude and practice amongst the dental professionals of different specialties about recent Covid 19 pandemic all over the world. A total of 250 participants were sent a survey questionnaire via Google Survey form. The responses were accepted in a 2 week time frame. The survey majorly focused on the clinical practice awareness and precautions taken by the dental professionals at their university / institute / college / private clinics while treating their patients based on which their knowledge and awareness were assessed. Demographic characteristics of study participants and their knowledge, awareness and practice related to Covid-19 were presented using descriptive statistics (mean and frequency distribution). RESULTSTwo hundred and forty-four (97.6 %) out of 250 participants surveyed responded to the questionnaire. Overall awareness amongst dental professionals was seen to be adequate with maximum correct responses received from the Teaching faculty of different institutes. Regarding the precaution level taken at the respective Institute / College / University the average score calculated on the base of responses was 6.92. CONCLUSIONSThe survey concluded that there is a dire need for regular educational interventions regarding the spread of the diseases and infection control at definite intervals. All dental professionals must be well aware of the protection kits available and their appropriate use during patient diagnosis and treatment planning
RESUMEN
Denture adhesives play a vital role in retention of complete dentures, wherever indicated. Dentists need to know about denture adhesives to be able to identify those patients who actually need them and to be able to educate them about the advantages, disadvantages and correct use of these products. The aim of the study was to evaluate the knowledge about denture adhesives among complete denture wearers indicated for use of denture adhesives visiting Dental Colleges in Western Maharashtra. METHODSThe study was conducted on 300 completely edentulous patients with conventional complete dentures indicated for use of denture adhesives. RESULTSPatients (n= 300) who were wearing ill - fitting complete dentures and required use of denture adhesives were selected, their response about knowledge was assessed by questionnaire survey and those who knew about it were instructed to demonstrate the application of denture adhesive to the intaglio surface of complete denture. 34.7% (n1= 104) of the total subjects (n= 300) had heard about denture adhesives. Out of these 104 subjects, 69.2% (n1= 72; CP= 24%) had used and 77.8% (n1= 81; CP= 27%) knew when to use denture adhesives. Out of 72 subjects who had used denture adhesive, only 30.5% (CP= 7.3%) could demonstrate the adequate technique to use denture adhesive. CONCLUSIONSKnowledge about use of denture adhesives for those who are in need per se has to be spread along with right technique of its use. The indication of its use, and correct technique/techniques of application, should be taught to the patients who demand the use of denture adhesives.
RESUMEN
Eclampsia increases the risk for both mother and foetus. The treatment aims to quickly bring about smooth reduction in blood pressure to levels that are safe for both, but avoiding any sudden drops, that may in themselves cause dizziness or foetal distress. Hence, this study was conducted to compare the efficacy of anti-hypertensive drugs in eclampsia.METHODS80 eclampsia patients were randomized into two groups: one received oral nifedipine and other intra-venous labetalol. Nifedipine group orally received 10 mg initially with repeated doses of 20 mg every 20 minutes up to maximum of 5 doses or until the therapeutic goal was reached. The other group received intravenous labetalol 20 mg initially followed by escalating doses of 40, 80, 80, and then 80 mg every 20 minutes until therapeutic goal was achieved or for a maximum of 5 doses. Once the therapeutic goal was reached, blood pressure was measured every 20 minutes till delivery.RESULTSMean time required to reach therapeutic blood pressure goal in nifedipine, and labetalol group was 45 ± 22.98 and 59.5 ± 25.41 minutes respectively. Total dose requirement was 1.65 ± 0.57 and 2.17 ± 0.74 mg respectively. The differences between two groups were significant. There was difference in urine output between the two groups as well. In the initial two hours, there was increased urine output in nifedipine group though it was statistically not significant. After two hours till 48 hours, this increased urine output in the nifedipine group was significant (p value 0.001).CONCLUSIONSnifedipine achieved the therapeutic blood pressure goal more rapidly than labetalol.
RESUMEN
Context: Relining with heat cure denture base resin is time‑consuming and the patient has to remain without dentures within this period. Recently, some autopolymerizing resins marketed as hard chairside reline systems with low exothermic heat allow the dentists to reline prosthesis directly in the mouth. However, the decision to use these materials must be based on physical properties such as dimensional accuracy that directly influences the accuracy of fit of the denture base. Aim: The aim was to compare the linear dimensional changes of two hard chairside reline resins with two laboratory heat cure resins at 3 times intervals after processing. Settings and Design: A stainless steel split mold (International Organization for Standardization 1567) was used for sample fabrication. Five measurements of the reference dimensions (AB and CD) were measured directly from the mold and the samples with a profile projector, and mean difference were calculated. Subjects and Methods: Forty samples were fabricated by incorporating the split mold into first pour of denture flasks and packing each of the chairside reline resins (“Kooliner” and “Ufi Gel Hard”) and laboratory heat cure resins (“Dental Products of India Heat Cure” and “Trevalon”). The mean difference in dimensional change at 3 times intervals (0 h, 4 days and 2 months) were calculated and subjected to statistical analysis. Statistical Analysis Used: One‑way ANOVA, RMANOVA and post hoc Tukey’s tests. Results: All resins showed different levels of significant shrinkage (P < 0.001) after processing (T0) ranging from −0.128 to −0.310 mm. After 4 days (T1), there was significant shrinkage (P < 0.001) ranging from −0.168 to −0.296 mm. After 2 months (T2), there was again significant shrinkage (P < 0.001) ranging from −0.018 to −0.216 mm. Chairside reline resins showed less dimensional shrinkage at each time interval than the laboratory heat cure resins. Conclusions: Hard chairside resins are dimensionally accurate than the laboratory heat cure resins.
