Aims: the aim of the current study is to assess the quantity of sorption and solubility seen in the soft denture liner with herbal (neem) and commercially (clinsodent) available denture cleanser. Materials and Methods: The cross sectional study was carried out in the Department of Prosthodontics at Sharad Pawar Dental College And Hospital between February 2021 and July 2021. 52 samples of heat cured acrylic resin of circular shape were prepared using a stainless steel mould. The resilient liner was applied to all the samples using a denture adhesive. All samples will then be desiccated for 24 hours to get a stable or conditioned weight W1. The samples will then be divided into 2 groups namely: Group A (clinsodent group) and the Group B (herbal denture cleanser group). All the samples were immersed daily in cleanser for 8 hour and then transferred to artificial saliva for rest 16 hours of the day. Solutions of artificial saliva and denture cleanser was changed daily for the entire period of study that is 7 days. Later, all the test samples were removed from saliva, wiped dry, weighed for saturated weight W2. - After desiccating again for 24 hours the samples were again assessed for renovated weight that is W3. Results: With respect to sorption and solubility it was found that the clinsodent group exhibited greater percentage of sorption when compared to the neem denture cleanser group after a period of 7 days, p-values of 0.0001,S. Conclusion: It can be established that the solubility and sorption values of clinsodent group were higher when compared to the herbal denture cleanser group. Overall, neem in the form of denture cleanser performed better than clinsodent.

Without having a reaction time, the pandemic has caused an unprecedented transformation in universities around the world, leading to a revolution from structured models anchored in the conception of transmission of training towards a teaching approach-learning saved thanks to the incorporation of technology. This study aims to verify whether the pandemic situation has influenced the digital competence self-perception of students. Comparing two groups during the academic years 2019/2020 and 2020/2021, the instrument used is the questionnaire for digital competence “DigCompEdu Check-In” for future teachers. After the educational intervention, group A (before COVID-19) presented higher self-perceptions of competence than group B (during COVID-19); the pandemic situation caused by COVID-19 has negatively influenced students’ self-perception of their digital skills in the pretest in the different dimensions under study. Before receiving the training, the group that did not experience the pandemic enjoyed a higher self-perception of their competencies than the group that experienced the pandemic. The data obtained indicate that the difference exists, and that it is statistically significant, and may be a consequence of the clear relationship between self-perception and the way in which students face reality through their personal and subjective vision.

Objective: To assess the frequency and severity of 24-hour respiratory symptoms according to COPD GOLD-ABCD classification (2017-version), the distribution of the patients with COPD into GOLD categories using mMRC (=2) or CAT (=10) scores, and agreement between these cut-off points. Methods: In this cross-sectional study (LASSYC study), 24-hour day respiratory symptoms were assessed by the Evaluating Respiratory Symptoms in COPD (E-RS) questionnaire, Nighttime Symptoms of COPD Instrument (NiSCI), Early Morning Symptoms of COPD Instrument (EMSCI), CAT and mMRC scores. Results: Among the 734 patients with COPD, 61% were male, age 69.6±8.7 years, FEV1% post-BD 49.1±17.5%, mMRC 1.8±1.0 and CAT 15.3±.8.1. By mMRC 33.7% were group-A, 29.2% group-B, 10.2% group-C and 26.9% group-D. By CAT 22.3% were group-A, 41% group-B, 4.8% group-C and 31.9% group-D. Using the mMRC the severity of E-RS, NiSCI and EMSCI scores increased from group A to D. Using the CAT, the groups B and D had the higher scores. Agreement between mMRC and CAT was 89.5% (Kappa statistics=75.7%). For mMRC score of 2, CAT score of =11 showed the maximum Youden's index (1.34). For mMRC score of 1, CAT score of =9 and =10 showed the maximum Youden's index (1.48). Conclusion: GOLD COPD classification by CAT seems to better discriminate 24-hour symptoms. Results do not support the equivalent use of CAT=10 and mMRC=2 for assessing symptoms.

Background: Primary headache is one of the most common disorders treated in neurology clinics. Globally, it has been estimated that the current prevalence of headache disorder in adults symptomatic, at least once within the last year, is about 50%. According to the Global Burden of Disease Study 2015, migraine was ranked as the third most common cause of disability worldwide. One of the significant migraines is migraine with aura, a frequent headache that occurs after or with sensory disturbances. Aim: This study aimed to identify and compare triggers in previously diagnosed patients with migraine with aura (MwA) to those who have not been identified with migraine with aura before but diagnosed according to a questionnaire survey distributed in the Kingdom of Saudi Arabia (KSA). Methods: Adults aged 18–50 years were randomly selected in the Kingdom of Saudi Arabia to participate in this non-interventional, multicentre, cross-sectional study. The study data was collected via an online questionnaire using the diagnostic criteria of the International Classification of Headache Disorders 2018 and the Cleveland Clinic Canada headache questionnaire. Results and Discussion: Of the 4.140 potentially eligible individuals, 302 were not previously diagnosed with migraine with aura but were diagnosed with a questionnaire (Group A), while 71 participants were already diagnosed (MwA) (Group B). A significant relationship was found among MwA and stress and anxiety, sleep disturbance, noisy places, exposure to lots of lights, prolonged computer work, hunger, fasting, studying for exams, and menstruation in Group A. Group B experienced all of the previous triggers in addition to weather changes, certain odors, and the consumption of cheese, bananas, and hotdogs. Conclusions: The trigger factors are common in individuals with MwA. Awareness of these triggers is essential for preventing the severe complications of MwA, hence, enhance the quality of life of patients.

Introduction: The technique of sealing is a widely accepted procedure for prevention of caries. The aim of our in vitro study was to compare the effect of two different curing units (traditional LED source and innovative laser diode lamp) on the integrity of fissure sealant material and its interface with tooth enamel. Materials and methods: Sixty healthy third molars were randomly assigned to two groups. In group A were teeth intended for polymerization by LED B lamp, and group B comprised teeth to be polymerized by an innovative laser diode. Both groups were treated with the traditional sealing technique, subjected to a metallization process, and analyzed by scanning electron microscope. Results: Micro-gaps between the sealant and the enamel were found in specimens in both A (43%) and B (40%) groups ( p=0.793), and sealant shrinkage was seen. Significant differences between the groups emerged in the percentage of perimetric micro-erosion sites (80% vs. 100%, p=0.010) and the presence of holes and micro-bubbles on the sealant surface (21% vs. 63%, p=0.001). Conclusions: Although macroscopic clinical polymerization occurred with both instruments, the microscopic evaluation showed significant differences between the studied groups in terms of perimetric micro-erosion sites and micro-bubbles, which were higher in laser-cured samples.

Implant connections must resist surgical and prosthetic procedures without deformation. This study evaluated the deformation of different internal connections (IC) of narrow dental implants (NDI) after their insertion in artificial dense bone. Thirty NDI, with different IC geometries, Group A (internal hexagon), Group B (tri-channeled), and Group C (four-channeled), with the same length and similar narrow diameters, were inserted in type II density bone blocks. Drilling protocols for dense bone from each implant manufacturer were followed. The Insertion torque (IT), connection length, vertex angles, and wall deformations were analyzed before and after the insertion of the implants. ANOVA (Analysis of Variance) and Tukey post-test were used for statistical comparisons. IT values were higher for Group A, surface damage, and titanium particles were observed in the IC in all the groups. Angle deformations between 5 and 70 degrees were present in all the groups, and the walls of Group B connection were the most affected by deformations (p < 0.05). Within the limitations of this experiment, it can be concluded that narrow diameter implants will suffer deformation of the implant connection and will also experience surface damage and titanium particle release when inserted in type II bone density.

Background: The optimal conservative treatment protocol of parotid abscess in children is evaluated.Material and Methods: This is a randomized, prospective, cross-sectional study conducted between November 2013 and June 2017 in Nobel Medical College and Teaching Hospital. Thirty children (below 14 years age) suffering from parotid abscess diagnosed by ultrasonography were included in this study. Recurrent parotid abscess cases were excluded. The children were divided into 2 groups by computer assisted randomization into15 patients each. Group A were treated with intravenous Clindamycin while group B were given intravenous Ampicilin + Cloxacillin combination. Results: Five patients of group B did not respond to treatment and were then put on intravenous Clindamycin. Three of these patients responded to treatment but 2 developed multi-lobulated fluctuation and required incision + drainage. Remaining 10 patients in group B and all patients in Group A responded to medical treatment without recurrence. Five patients in group B developed severe diarrhea during antibiotic treatment but none of the patients in group A had this complaint. No patient developed any complications like parapharyngeal abscess or septicemia. Conclusion: Parotid abscess in children can be managed conservatively with intravenous Clindamycin without the need for incision and drainage. Journal of Nobel Medical College Volume 7, Number 1, Issue 12, January-June 2018, Page: 56-59

Introduction: Fluoride is known to reduce demineralization and enhance remineralization which is desirable around orthodontic brackets. Material and methods: This study was carried out to determine the rate of fluoride release, fluoride content of enamel, and surface alteration of enamel from orthodontic bonding agents. Thirty extracted maxillary first premolars were divided into 2 groups of 15 teeth each. Group A—teeth were bonded with a chemically cured orthodontic bonding agent containing fluoride (Rely-a-Bond, Reliance, Itasca) and group B—teeth were bonded with a light-cured orthodontic bonding agent containing fluoride (Light Bond Reliance, Itasca). All individual sample teeth were used to estimate fluoride release and fluoride content of enamel. The same samples were also used to evaluate enamel surface alterations. The rate of fluoride release from the above 2 orthodontic bonding agents were measured in artificial saliva on day 1, 2, 3, 4, 5, 6, 7, 14, 30, 60, and 90. The fluoride content of the enamel was evaluated on day “0” and day “90” of bonding. The samples were also evaluated for the surface changes in enamel using scanning electron microscope (SEM). Results: The results showed that (a) chemically cured and light-cured bonding agent showed a dramatic decrease in the concentration of fluoride release from day “1” to day “2,” (b) the concentration of fluoride release kept decreasing from day “1” to day “90” of measurement in both the groups, and (c) SEM of the bracket margins bonded with chemically cured bonding agent and light-cured bonding agent revealed particle depositions of irregular shape and size on day “90.” Conclusion: Light-cured bonding agent (Light Bond) released higher concentration of fluoride as compared to chemically cured bonding agent (Rely-a-Bond). Light-cured bonding agent (Light Bond) showed higher increase in fluoride content of enamel than chemically cured bonding agent (Rely-a-Bond).

Abstract Purpose: The purpose of this in vitro study was to evaluate marginal fit of cobalt- chromium (Co-Cr) copings fabricated by direct metal laser sintering system (DMLS) and conventional lost-wax technique (LW). Materials and method: Forty tooth preparations were carried out over extracted mandibular molars. They were divided into two groups A and B of 20 each. For group A Co-Cr copings were fabricated by direct metal laser sintering (DMLS) and for group B by lost wax technique (LW). Glass –ionomer cement (GIC) was used to tack the copings over their preparations. Marginal fit was then evaluated directly under the stereomicroscope. Results: The mean marginal gap of group A was 27.9 ± 2.4 μm and group B was 40.4 ±6 μm. Statistical analysis using t - test showed highly significant difference (P>.05) between the marginal mean of the DMLS (group A) compared to LW (group B). Conclusion: The DMLS copings demonstrated superior marginal fit compared to that of conventional Co-Cr casted copings.
