Patients' Readiness Towards Teledentistry in the Malaysian Urban Population Attending an Undergraduate Teaching University.

Introduction: COVID-19 disease has resulted in suspension of all nonurgent routine dental treatments. In view of COVID-19 situation, social distancing, movement restriction orders, and affected health care systems, there is an urgent need to resume and deliver oral health care remotely. Hence, alternative means of dental care should be available for both patients and dentists. Therefore, this study aims to assess patients' readiness for teledentistry in Malaysian urban population attending an undergraduate teaching university. Methods: A cross-sectional study was conducted among 631 adult patients visiting the Faculty of Dentistry, SEGi University, from January 2020 to May 2021 in Selangor, Malaysia. A validated, self-administered, 5-point Likert scale online questionnaire comprising five domains was administered. (1) Patients' demographics and dental history, (2) patients' access to teledentistry, (3) patients' understanding towards teledentistry, (4) patients' willingness, and (5) barriers in using teledentistry were used to collect the required information. Results: Six hundred and thirty-one (n = 631) participants responded to the questionnaire. Ninety percent of patients were able to connect to Wi-Fi services independently and 77% participants were comfortable using online communication platforms. Seventy-one percent of the participants agreed that video and telephone clinics can reduce chances of infection rather than face-to-face consultation during the pandemic. Fifty-five percent of patients felt that virtual clinics would save time and 60% thought it could reduce travelling costs. Fifty-one percent showed their willingness to use video or telephone clinics when implemented at onsite clinics. Conclusion: Our study shows the readiness of patients to accept teledentistry as an alternative method of oral care if appropriate training and education are provided. The results of this study have prompted an increase in patients' education and shown a need to train clinicians and patients to integrate this technology at SEGi University. This might facilitate unhindered dental consultation and care in all situations.

Effect of lip thickness and competency on soft-tissue changes.

INTRODUCTION: Improvement in facial esthetics is a major reason for seeking orthodontic treatment. Soft tissues responsible for esthetics show a variable response to the movement of underlying teeth during orthodontics. METHODS: The purpose of this cross-sectional study was to analyze the response of soft tissues and compare it among groups presenting with different lip thickness and competence. It was carried out on 37 patients with Class I and Class II Division 1 malocclusion who had undergone extractions of maxillary first premolars and had completed their orthodontic treatment. Data were obtained by corresponding lateral cephalometric radiographs taken before and at the end of orthodontic treatment. Association was analyzed with a Pearson correlation test. Differences among groups exhibiting varying competency and lip thickness were tested with an independent sample t test. A P value of ≤0.05 was considered statistically significant. RESULTS: Pearson correlation revealed significant associations among incisor tip retraction with lip base retraction (r = 0.68), lip base thinning (r = 0.41) and vermilion retraction (UV) (r = 0.73). Regression analysis showed a moderate increase in lip length (AB) and thickness at vermilion, which were 0.11 mm and 0.15 mm for each mm of incisor retraction at the tip, whereas stronger effects were observed for UV (0.38 mm) and lip base retraction (0.55 mm). There was significantly more lip base thinning (P = 0.03) and UV (P = 0.04) in the incompetent group compared with the competent group. The AB increased significantly in the sample with thicker lips (P = 0.01). Pearson correlation coefficient showed a strong association of lip retraction at the base and vermilion with the incisor movement at the cervical area, for competent and incompetent lips, and thicker and thinner lips. CONCLUSIONS: Lip retraction at vermilion and lip base thinning was significantly more in patients with incompetent lips, whereas the AB increased significantly more in the group with thicker lips.

Relationship of early weaning and non-nutritive sucking habits with facial development.

OBJECTIVE: To determine the frequency of malocclusion features, convex facial profile and non-nutritive sucking habits among children with and without early weaning. METHODS: The cross-sectional study was conducted at the National Institute of Child Health, Karachi, from June to December 2020, and comprised of either gender aged 3-6 years. The subjects were clinically examined, and details of lactation period, bottle feeding, thumb and pacifiers sucking were gathered from the parents to assess association with malocclusion. Data was analysed using SPSS 20. RESULTS: Of the 180 subjects, 100(55.5%) were boys and 80(45.5%) were girls. There was significant association of early weaning with non-nutritive sucking habits, absent primate spaces, deviated midlines, and complete overbite (p<0.05). Breastfeeding <2 years was significantly associated with anterior crossbite (p<0.05). Early weaning had no association with convex facial profile, distoclusion, anterior and posterior crossbite and increased overjet (p>0.05). Non-nutritive sucking habits had significant relationship with deviated dental midlines (p>0.05). Conclusion: Early weaning was found to be a factor in establishing non-nutritive sucking habits, and was strongly associated with crowding, disturbed vertical overlapping of incisors and developing decreased facial height. Breastfeeding for less than the recommended duration had a tendency to lead to anterior cross-bite.

A qualitative study of trainer and trainee perceptions and experiences of clinical assessment in post-graduate dental training.

BACKGROUND: The implementation of workplace-based assessment (WBA) needs to ensure the achievement of pre-set competences but may look different across varying contexts, such as in post-graduate dental education. The purpose of this study is to explore the perception of residents, faculty members and alumni concerning their experience with clinical assessment, and what configurations they consider as optimal to maximise the entailed learning experience. METHODS: This study relied on a qualitative descriptive design using two data collection tools: focus group sessions, and semi-structured, one-to-one interviews. Data were triangulated from three sources: residents, faculty members and alumni. The data were inductively analysed based on constructivist epistemology. This was done using the Thematic Analysis approach, facilitated by NVivo software. RESULTS: The analysis revealed two mutually exclusive themes: process and people. Within process, variables related to quality, workflow and feedback surfaced. As for the people theme, the main two group of stakeholders referred to in the related analysis were the trainees and the trainers. DISCUSSION: There are many variables that need to be considered when developing an evidence-driven WBA. In addition, factoring into the design of the WBA the perception of the main stakeholders will enable contextualisation which is expected to raise the reliability of the adapted tools. CONCLUSION: This study introduced a framework that could support post-graduate universities in their journey towards developing context-specific WBA.

Face-to-face and e-learning during the COVID-19 pandemic: A Pakistani dental undergraduates perspective.

BACKGROUND: Globally, educational institutes have been obliged to make a quick transition from traditional face-to-face teaching to e-learning during the coronavirus disease 2019 (COVID-19) pandemic, which has purportedly created various barriers to achieving desired learning outcomes. OBJECTIVE: The aim of our study was to assess the perceptions of undergraduate dental students regarding online and physical learning in Pakistan. METHODS: This cross-sectional study was conducted from January to March 2022. The study comprised dental students from 1st to 4th years who were above the age of 18 and of either gender. The Google Forms questionnaire was created to evaluate the quality and efficiency of online and physical learning among dentistry undergraduates. RESULTS: In a survey of 246 students, 70.3% strongly agreed that they would prefer face-to-face instruction over e-learning. There was a statistically significant difference in the improvement of students' technical skills (p = 0.01), accessibility to instructors (p = 0.01) and classmates (p = 0.02), value of technology (p = 0.03), improvement of oral communication skills (p = 0.01), promotion of hybrid model learning after the pandemic (p = 0.01), and utilization of tutorial services (p = 0.04) between different year of study. CONCLUSION: Pakistani dental students indicated satisfaction with numerous aspects of e-learning, such as technical skills, accessibility to instructors and classmates, the value of technology, improvement of oral communication skills, promotion of hybrid model learning, and utilization of tutorial services compared to face-to-face education concerning the year of study.

Comparative assessment of various cephalometric facial planes with intercanine width in orthodontic patients.

OBJECTIVE: The study was conducted to evaluate the relationship of various cephalometric skeletal patterns in the vertical and anteroposterior planes with intercanine width in untreated orthodontic patients. METHOD AND MATERIAL: This study included dental cast and cephalometric radiographs of 100 patients (69 females and 31 males) of the age range 13 to 33 years. Skeletal parameters including SNA, SNB, SNMP angles were found from lateral cephalometric radiographs. Intercanine widths including upper intercanine widths (UICW) and lower intercanine widths (LICW) were measured by a digital caliper. RESULTS: The correlation of intercanine width with SNA, SNB, and SNMP angles was analyzed by applying Pearson correlation coefficient. According to statistical analysis, the only insignificant correlation was analyzed between UICW with SNB and LICW with SN-MP. CONCLUSIONS: The overall result showed statistically significant relationship of various cephalometric skeletal patterns in the sagittal and vertical planes with intercanine width.

However, certain medications, therapeutic radiation and certain autoimmune diseases can cause a reduction in the salivary flow. The aim of this report was to review and highlight the indications and techniques of salivary gland engineering to counter hyposalivation. This report concludes that in the literature, numerous strategies have been suggested and discussed pertaining to the engineering of salivary gland, however, challenges remain in terms of its production and accurate function. Dedicated efforts are required from researchers all over the world to obtain the maximum benefits from salivary gland engineering techniques.

Human saliva can be a diagnostic tool for Zika virus detection.

Zika virus (ZIKV), an Aedes mosquito-borne flavivirus, has captured public health attention worldwide. Initially, the virus was reported in Africa and Asia. However, the outbreak of ZIKV in Brazil and the United States of America demonstrated the global health risk. Symptoms of ZIKV infection vary from mild fever, rash, and joint pain to an apparent increase in microcephaly in infants and severe manifestations including Guillain-Barré syndrome in adults. Such consequences led to enormous health challenges, and consequently the World Health Organization declared a global health emergency. This review incorporates all aspects of ZIKV that could significantly impact human health, including epidemiology, clinical presentation, possible complications, cutting-edge therapeutic management of ZIKV infection, and latest developments in ZIKV diagnosis, particularly the value of human saliva as a diagnostic fluid.

Influence of phototherapy on adhesive strength and microleakage of bleached enamel bonded to orthodontic brackets: An in-vitro study.

AIM: The aim of the present in-vitro study was to explore bleached enamel reversal with phototherapy (Er,Cr:YSGG) when using two dissimilar bonding system to bond brackets on microleakage and shear bond strength. MATERIAL AND METHODS: Amongst one twenty samples, ninety samples were bleached using 35% hydrogen peroxide. After the bleaching procedure, the teeth were randomly divided into three groups according to surface conditioning treatment (n = 30 each). Group 1: treated with Er,Cr:YSGG (ECL) Group 2: 10% sodium ascorbate (SA) and Group 3: Bleached only (BO). Based on the type of adhesive, specimens were further classified into eight subgroups. In subgroup 1,2,3 and no treatment (NT) (n = 15) adhesive Transbond XT was applied on already etched surface and these subgroups were named as NT-TEP, BO-TEP, ECL-TEP and SA-TEP. Similarly, in subgroup 5,6,7 and NT specimens (n = 15) were conditioned with Transbond Plus self-etching primer and these subgroups were named as NT-SEP, BO-SEP, ECL-SEP and SA-SEP. Samples from each subgroup were exposed to increasing load for evaluation of shear bond strength. Microleakage among subgroups were tested by immersing samples in Methylene blue prior one day. Analysis of variance and Tukey multiple comparisons test was used to assess data. RESULTS: The maximum and minimum bond strength was observed in group NT-TEP [17.14(2.54)] and BO-SEP [6.14(0.215)] respectively. Samples conditioned with phototherapy ECL-TEP [16.14(1.231)] exhibited comparable bond strength to specimens conditioned with sodium ascorbate (SA-TEP) [16.72(1.298)]. Similarly, bond strength values of ECL-SEP [13.43(0.921)] and SA-SEP were comparable. The highest microleakage score was demonstrated in BO-SEP [83.21(38.21)] whereas, the lowest microleakage scores were displayed in NT-TEP [23.73(13.45)]. CONCLUSION: Er,Cr:YSGG phototherapy reversal on bleached enamel with etch and rinse adhesives has a potential to be used in clinical settings alternate to conventional sodium ascorbate when bonding orthodontic brackets.
