An evaluation of antagonist enamel wear opposing full-coverage zirconia crowns versus other ceramics full-coverage crowns and natural enamel - An umbrella review.

AIM: The aim of this umbrella review was to systematically review the systematic reviews on antagonist enamel wear opposing zirconia crowns compared to other ceramics and natural enamel. SETTINGS AND DESIGN: This was an umbrella review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. MATERIALS AND METHODS: An electronic search of PubMed, Cochrane Central, EBSCOhost, and Google Scholar search engines for articles published from January 1, 2013, to January 1, 2023, was conducted using keywords "enamel wear," "zirconia," "feldspathic," "dental ceramics," and "Y-TZP" to identify systematic reviews on antagonist enamel wear opposing zirconia crowns compared to other ceramics and natural enamel. STATISTICAL ANALYSIS USED: Qualitative analysis. RESULTS: A total of 86 articles were obtained through electronic search, of which four articles were selected after abstract screening that met the inclusion criteria for evaluating antagonist enamel wear. As compared to feldspathic groups, zirconia had substantially less antagonist wear, while surface polishing exhibited less enamel wear than glazing. Because of the heterogeneity in study design, measurement methods, and outcome variables, a meta-analysis was not possible. CONCLUSIONS: Over time, the opposing enamel wear caused by polished monolithic zirconia will be either equal to or less than that of natural enamel wear. Polished monolithic zirconia also maintains lower values of enamel wear compared to metal ceramics, feldspathic porcelains, and lithium disilicate.

COVID-19 vaccination acceptance and adherence among pregnant and lactating high-risk group individuals of Maharashtra State, India.

BACKGROUND: Since the outbreak of the pandemic, the release of the COVID (Corona Virus Disease)-19 vaccine was highly anticipated. Nevertheless, vaccine availability does not symbolize the end of pandemic due to ongoing vaccine hesitancy and anti-vaccination movements. The objective of this study is to evaluate COVID-19 vaccine acceptance among pregnant and lactating individuals in Maharashtra state, India. MATERIALS AND METHODS: A descriptive cross-sectional study was conducted via a hybrid approach using various digital portals such as Whatsapp, telegram, and physical distribution to those who did not have access to smartphone devices. A probability proportional sampling strategy was deployed. A pre-validated structured self-administered questionnaire tool designed by Freeman et al. 2020 (Oxford COVID-19 vaccine hesitancy scale) was used, which consisted of seven close-ended targeted and focused questions. Analysis of several survey items and vaccine acceptance was conducted using the Chi-square test. RESULTS: Analysis revealed that 58% of individuals were willing to take vaccines after government approval and 26% of individuals showed hesitancy toward vaccination. When compared, lactating individuals showed less vaccine hesitancy (22%) than pregnant individuals (27%). The maximum vaccine hesitancy was observed in the third trimester of pregnancy (29.5%). CONCLUSIONS: Trust in vaccines is a crucial factor and is dependent on the ability of the government in promoting vaccines through effective communication; this can be one of the reasons for the high level of acceptance and awareness toward COVID-19 vaccination in this study.

Multidimensional perfectionism trends among various core and allied health care professionals in a major Indian metropolitan city of Western India.

BACKGROUND: This exploratory study was done to assess the multidimensional perfectionism trends among various core and allied health care professionals in a major Indian metropolitan city of western India. Unlike other scales, here we considered both individual and intersubjective components of perfectionism by introducing three trait dimensions - self-oriented perfectionism, other-oriented perfectionism, and socially prescribed perfectionism. MATERIALS AND METHODS: A cross-sectional descriptive type of study was conducted with total sample consisting of 500 participants with the main motive of evaluation and comparison of the multidimensional perfectionism among interns of the core and allied health care professionals from fields of medicine, dentistry, ayurveda, and homeopathy residing in the major Indian metropolitan cities of western India. RESULTS: This study showed that under the self-oriented domain, highest mean score is of medical faculty (73.97). In other-oriented domain, dental (62.62) and homeopathy (62.38) professionals have almost similar mean. Lowest being of ayurveda (61.65) compared to the highest score of the medical fraternity (67.62). In the socially prescribed domain, medical professionals (65.53) have the highest mean though it is the lowest mean value of the medical faculty compared to other two domains. Chi-square test is applied to the data for the questions among all the three domains. Correlation has been deduced by applying Pearson's correlation to the collected data from the study. The degree of correlation between self-oriented with self-oriented is 1, self-oriented with other-oriented is 0.763, and that of self-oriented with socially oriented is 0.678. CONCLUSION: Medical professionals scoring maximum in self-oriented perfectionism compared to other two domains reflect their extreme personal standards. Medical professionals are followed by dental professionals in self oriented perfectionism who are demanded of perfection in their routine practice. Ayurveda and homeopathy professionals scored better in other-oriented and socially prescribed perfectionism attributing to their sentiments of fulfilling the expectations and demands of others.

Root canal anatomy of human permanent mandibular incisors and mandibular canines: A systematic review.

Mandibular incisors and canines show variations in their root canal anatomy. It is imperative to be aware of these variations to lower the frequency of missed canals. The objective was to systematically review the existing studies to recognize the root and root canal anatomy of the mandibular incisors and canines among the population of various geographical locations, as studied by different methods. This systematic review was registered in the International Prospective Register of Systematic Reviews database under the number CRD42020185146. An exhaustive search was undertaken in three electronic databases - MEDLINE PubMed, EBSCOhost, and Google Scholar - along with hand-searching for the identification of studies. Studies were selected following strict inclusion and exclusion criteria. Selected studies were scored using the Joanna Briggs Institute Critical Appraisal tool for prevalence studies to determine the risk of bias. This review included data from 26 countries including the analysis of 71,404 mandibular anterior teeth. The risk of bias of all included studies was either low or moderate. Overall, it was seen that the percentage of second canals was higher in lateral than in central incisors. Mandibular canines occasionally showed the presence of two roots. Deviations in anatomy were high in the Middle Eastern European countries and the Indian subcontinent. Limitations are as follows: lack of homogeneity across data reported in the studies concerning the methods used to study the root canal anatomy. Diversities seen in the root canal configurations of mandibular incisors and canines vary according to ethnicity, and thus, one must have a thorough knowledge before commencing endodontic treatment.

Development and validation of a risk-of-bias tool for assessing in vitro studies conducted in dentistry: The QUIN.

STATEMENT OF PROBLEM: Systematic reviews and meta-analyses have emerged as forerunners of evidence-based dentistry, but assessing the quality of the available research is essential so that it can be applied to clinical practice. While a wide variety of risk-of-bias tools are available, each specifically developed for different study designs, a comprehensive tool exclusively framed to assess the quality of in vitro dental studies is lacking. PURPOSE: The purpose of this study was to develop and validate a tool to evaluate the quality and risk of bias of in vitro dental studies. MATERIAL AND METHODS: A Delphi panel was established to conceptualize and develop the Quality Assessment Tool For In Vitro Studies (QUIN Tool). The tool was evaluated by using content validity and reliability testing methods. RESULTS: The QUIN Tool includes 12 points along with scoring and grading options to allow clinicians to evaluate the quality of in vitro studies. This tool shows good content validity and reliability. CONCLUSIONS: The QUIN Tool is user-friendly, efficient, and effective for evaluating the risk of bias of in vitro studies.

Assessment of Knowledge, Attitude, and Practices Regarding Advanced Local Anesthetic Techniques among Students Attending a Private Dental College in Navi Mumbai, India: A Cross-sectional Study.

Aim and objective: Local anesthesia (LA) administration is an anxiety-provoking phenomenon in patients. Several alternative and advanced techniques make LA administration patient-friendly. This study assesses the knowledge, attitude, and practices of these advances, creating awareness and encouraging further studies and innovations to make these techniques more accessible, available, and economical to be utilized in the Indian population for controlling pain by targeting the budding dentists who actively imbibe and are abreast with the current state of affairs. Methods and materials: A descriptive cross-sectional questionnaire-based study was conducted among the undergraduate and postgraduate students of a private college in Navi Mumbai. The self-administered questionnaire contained 13 questions. The data was analyzed using Statistical Package for Social Sciences (SPSS) version 17 software and a Chi-square test were applied. Results: A majority of the respondents were unaware of the alternative techniques (59.4%) with a significant difference between undergraduates and postgraduates. 95.7% thought conventional methods caused dental anxiety and 55.1% thought alternatives would be better. The pain management techniques currently used were mostly reassurance and distraction (84.2%) and Topical anesthesia (74.9%). Only 9.6% had actually practiced these techniques, the reason for inexperience being inadequate knowledge. Out of those who had used these techniques, 47.82% saw positive results with patients experiencing less pain. Conclusion: Knowledge of advanced local anesthetic techniques in the dental fraternity is necessary to enhance practice and provide the best care to the patients. Its inclusion in the curriculum with adequate practical training shall ensure its use efficiently. Clinical significance: Today dentistry is propelling toward minimally invasive, painless, and patient-friendly procedures. The incorporation of advanced LA techniques to help achieve this goal begin with assessing its awareness among future dentists which would help make them accessible and affordable and contribute toward providing patients a holistic treatment.

Effect of different finish line preparations on the marginal and internal adaptation of cobalt-chromium metal alloy copings fabricated by using CAD-CAM technology: A systematic review and meta-analysis.

STATEMENT OF PROBLEM: The marginal and internal adaptation of a fixed dental prosthesis depends on a variety of factors, finish line designs being one of them. A clear consensus as to which finish line design can provide a better marginal and internal adaptation with respect to cobalt-chromium metal alloy copings fabricated by using computer-aided design and computer-aided manufacturing (CAD-CAM) technology is lacking. PURPOSE: The purpose of this systematic review and meta-analysis was to evaluate the effect of different finish line preparations on the marginal and internal adaptation of cobalt-chromium metal alloy copings fabricated by using CAD-CAM technology. MATERIAL AND METHODS: Electronic (PubMed, Cochrane, EBSCOhost, and Google Scholar) and manual searches were conducted for articles published from January 2010 to December 2020 to identify relevant studies evaluating the effect of different finish line preparations (chamfer, deep chamfer, shoulder, rounded shoulder) on the marginal and internal adaptation of cobalt-chromium metal alloy copings fabricated by using CAD-CAM technology. RESULTS: A total of 573 articles were obtained via electronic search, and 10 articles were obtained through manual search, of which 24 in vitro studies were selected after title, abstract, and full-text screening and were included for both qualitative and quantitative analyses. The marginal adaptation was evaluated under the parameters of marginal gap, absolute marginal discrepancy, and vertical marginal discrepancy, whereas internal adaptation was evaluated under the parameters of internal gap, cervical discrepancy, axial discrepancy, and occlusal discrepancy. The methods of CAD-CAM fabrication (direct metal laser sintering, hard milling, and soft milling) were considered under the subgroup analysis. CONCLUSIONS: An overall better marginal and internal adaptation was observed with shoulder and rounded shoulder finish line designs when CAD-CAM methods were used for coping fabrication. Marginal and internal adaptation in chamfer and deep chamfer finish line designs showed better results with soft milling and direct metal laser sintering methods, whereas shoulder finish line showed better results with hard milling.

Assessment of knowledge, attitude and practice regarding intellectual property rights among dental task force attending private dental colleges in Navi Mumbai: a cross-sectional study.

Intellectual property rights such as Copyright, Trademark, Patents and Trade secrets etc. help us to gain some protection against certain inventions by acknowledging the founder. In today's industry it is agreed that Intellectual Property Rights has a big role to play. This current study envisages the knowledge, attitude, practice regarding Intellectual Property Rights among dental task force attending private dental colleges.The survey was conducted among students of which were Interns, Post Graduates, faculty members and other dental surgeons attending private dental colleges in Navi Mumbai. The subjects of this study comprised of a total of 1020 students, faculty members and other dental surgeons from five different private dental institutes. The survey includes closed ended questions. Data analysis was performed using SPSS software version 17. Explaining calculations were used to summarize all the answers. A total of 889 students, faculty and other dental surgeons from private dental colleges responded. Results showed that about 83.5% believe the statement "Articles and other publications are protected by copyright." 66.6% of participants would select trademark in order to protect their clinic or organization name. About 38.7% were aware of the term Intellectual Property Rights. It also suggests that only 10.9% have attended any seminar/conference pertaining to IPR. The students and faculty members have an overall sense of eagerness to learn and gain more knowledge based on IPR. Thus conducting more workshops and seminars based on IPR should be encouraged.

Include-integrate-involve: Deciphering oral healthcare providers' professional demeanor towards sexual and gender minority cohorts in a metropolitan city of western India.

OBJECTIVES: The Sexual and Gender Minorities (SGM) have been subject to disparities in healthcare. This study gauges and compares the demeanor of oral health task force in privately-funded and government-funded dental schools of India towards SGM cohorts. STUDY DESIGN: A descriptive, cross-sectional, point prevalent study was conducted following standard statements of the STROBE guidelines and using the Medical Condition Regard Scale (MCRS). It was conducted among the clinical oral health taskforce hailing from private-funded and government-funded institutes. METHODS: One-way ANOVA test computed differences in mean MCRS scores among the undergraduates, postgraduates and faculty. Independent t-test compared responses of participants from private institutions and government institutions using SPSS version 17 statistical software. RESULTS: All the respondents were mostly but not completely satisfied to work with SGM patients (MCRS score â€‹= â€‹4.55 â€‹± â€‹1.114) indicative of some underlying hesitance. Though everyone had a positive regard, undergraduates and those from private institutions felt more compassionate and showed greater willingness to put in extra efforts to help them feel at ease (P-value <0.05). This is interpretive of more receptiveness towards specialized training and policy reforms of these individuals. CONCLUSION: The significant differences between institutes and designations highlight disparities in knowledge and training resulting in the underlying hesitation. Health education urgently needs a targeted and focused SGM-related training program to deconstruct these disparities and provide equitable oral and general health for all individuals irrespective of their sexual orientation.

Comparative evaluation of anesthetic efficacy of 4% articaine infiltration versus 2% lignocaine inferior alveolar nerve block for extraction of primary mandibular molars: A prospective, split-mouth, randomized controlled trial.

CONTEXT: Control of pain during dental treatment is an essential aspect of pediatric dentistry. AIMS: This study was conducted to evaluate and compare the anesthetic efficacy of 4% articaine buccal infiltration with 2% lignocaine inferior alveolar nerve block (IANB) for primary mandibular molar extractions. SETTINGS AND DESIGN: The study was a prospective, split-mouth, randomized controlled trial. METHODS: Bilateral symmetrical carious primary mandibular molar (n = 92) extractions in 46 healthy children aged 5-10 years were included in this randomized controlled trial. Extraction was performed on one side using 4% of articaine buccal infiltration and on the contralateral side using 2% lignocaine IANB in two subsequent appointments. Pain and behavior were assessed at baseline, during injection and extraction using Wong-Baker Faces Pain Rating Scale, Modified Behavior Pain Scale (MBPS), and Frankl Behavior Rating Scale. STATISTICAL ANALYSIS USED: Values thus obtained were statistically analyzed by one-way analysis of variance test and compared using independent samples test. RESULTS: According to MBPS, the mean value of pain experienced in the form of cry during injection was reported to be more for 2% lignocaine IANB (1.76) as compared to 4% articaine buccal infiltration (1.30), which was statistically significant (P = 0.024). Comparison of behavior depicted showed no statistically significant difference between the groups. CONCLUSION: Buccal infiltration with 4% articaine can be utilized as an effective alternative to 2% lignocaine IANB for primary mandibular molar extractions.

Root canal morphology of South Asian Indian mandibular first, second, and third molar: A dye penetration and clearing study.

CONTEXT: Studying in detail the root canal morphology specific to the Indian mandibular molars will help discern whether the root canal anatomy patterns resemble those reported internationally or are different from it. AIM: The aim is to study the root canal anatomy of Indian permanent mandibular first, second, and third molar teeth using a tooth clearing technique. METHODS: The root canals of a total of 300 extracted Indian mandibular molars consisting of 100 first, second, and third molars each were accessed and injected with India ink, after which they were subjected to the clearing technique. STATISTICAL ANALYSIS: Data was analyzed using descriptive statistics for the computation of percentages using SPSS version 21. RESULTS: Of the hundred first molars, 90% of teeth were two rooted with three canals, 79% had two apical foramina. 70% mesial roots of the three-rooted type showed Type I, whereas 100% distal roots and distolingual roots showed Type I Vertucci's anatomy. About 70% mesial roots of two roots showed Type II and 90% distal canals showed Type I configuration. Among the second molars, five (5%) were single-rooted, ninety-one (91%) teeth were two rooted and four (4%) had three roots. Among the mandibular third molars, fifteen (15%) teeth had one root, sixty-three (63%) teeth had two roots, eighteen (18%) teeth had three roots, and four (4%) teeth had four roots. CONCLUSIONS: The root canal anatomic features of mandibular molars showed differences in the frequency of particular anatomic types as compared to mandibular molars from other racial backgrounds. Further comparative studies on inter-racial anatomic characteristics from various geographic locations would be beneficial.

Effect of Immediate Dentin Sealing on Polymerization of Elastomeric Materials: An Ex Vivo Randomized Controlled Trial.

STATEMENT OF PROBLEM: Interactions are suspected between resin coating and elastomeric impression material. PURPOSE: The purpose of this study was to identify possible interactions between two impression materials and resin-coated tooth surfaces. MATERIALS AND METHODS: Extracted molars (n = 10) underwent 1 of the 4 procedures: control group (unsealed tooth surface/impression); IDS group (immediate dentin sealing/impression); IDS/AB group (immediate dentin sealing/air blocking/impression); IDS/AB-P group (immediate dentin sealing/air blocking/pumicing/impression). Dentin bonding agents used were Adper single bond 2 and Clearfil SE bond. Impression materials used were Impregum Soft (polyether) and Aquasil (A silicone). A stereomicroscope was used to detect any residual impression material on the bonded tooth surface. RESULTS: The IDS group showed 100% faulty impressions. Air blocking the resin coating did not completely eliminate the oxygen-inhibited layer of Adper single bond 2. Clearfil SE Bond along with Aquasil generated ideal impressions in group IDS/AB, while all other combinations resulted in faulty impressions. The IDS/AB-P group yielded ideal impressions with Aquasil but generated faulty impressions with Impregum soft in most specimens. CONCLUSION: Immediate dentin sealing should be followed by air blocking and pumicing to generate ideal impressions with Aquasil (A silicone). Impregum Soft (polyether) is not recommended in combination with immediate dentin sealing. HOW TO CITE THIS ARTICLE: Khakiani MI, Kumar V, et al.

Utilization of services and referrals through dental outreach programs in rural areas of India. A two year study.

BACKGROUND: Oral health care services are often sparse and inconsistent in India therefore it is often difficult for poor people to get access to the oral health care services. The approach by dental institutions with the help of community outreach programs is a step ahead in overcoming this situation. OBJECTIVES: The study was conducted to evaluate the number of patients, disease pattern and the services provided in the outreach programmes and also effectiveness of patient referral. METHODS: A retrospective study was conducted and the data were obtained from records of outreach programs conducted, in last 2 years by Pacific Dental College and Hospital. The data were analysed using descriptive statistics for the computation of percentages Chi-square test was applied to know the association of effectiveness of referral with age and gender. Confidence level and level of significance was fixed at 95% and 5% respectively. RESULTS: A total of 22982 individuals in the age group of 4-80 years attended the outreach program. Dental caries (42.3%), periodontal diseases (63.2-69.0%) and dental fluorosis (33.7-35.0%) were commonly observed diseases. Effectiveness of referral was significantly high among the middle age adults and females (P<0.05). The effectiveness of referral was highly improved in 2013 after establishment of certain guidelines and strategies. CONCLUSION: The approaches by dental institutions with the help of community outreach programs can spread awareness and disseminate treatment and thereby enhancing access to care and eliminating access to care within the rural communities.

Oral health status of fishermen and non-fishermen community of Kutch district, Gujarat, India: a comparative study.

BACKGROUND: Fishing is one such hazardous occupation, which involves irregular diet, stress, alcoholism, tobacco and pernicious habits. Fishermen have lower socio-economic status and their illiteracy adds to their poor oral hygiene, which may influence general and oral health. AIM: The aim of the study was to assess and compare the oral health status of fishermen and non-fishermen population of Kutch District, Gujarat, India. MATERIALS AND METHODS: A descriptive cross-sectional survey was conducted to assess and compare the oral health status of the fishermen and non-fishermen community of Mundra taluka of Kutch district, Gujarat, India, from January 2013 to June 2013. RESULTS: Fishermen had significantly higher periodontal disease and dental caries than non-fishermen group (p = 0.001). Malocclusion was significantly higher in non-fishermen group (p = 0.001). Extraction was the most prevalent treatment need among both groups. Occupation and educational status were respectively identified as the best predictors for dental caries and periodontal disease. CONCLUSIONS: Findings of the present study suggest that oral health status of the fishermen population was relatively poor, with high caries prevalence and poor periodontal health when compared to the non-fishermen population. In the light of high treatment needs of the study population, health policy that emphasises oral health promotion and prevention would seem more advantageous in addition to traditional curative care.

Comparative Assessment of Intelligence Quotient among Children Living in High and Low Fluoride Areas of Kutch, India-a Pilot Study.

BACKGROUND: Long-term ingestion of large amounts of fluoride can lead to potentially severe skeletal problems and neurological consequences. The study was conducted to assess and compare intelligence quotient of children living in high and low fluoride areas in Kutch, Gujarat, India. METHODS: A cross-sectional descriptive survey was conducted among 100 school children aged 8 to 10 years, living in Kutch District, Gujarat, India during July 2012. Mundra (2.4 to 3.5 mg/L) and Bhuj (0.5mg/L) were the two villages randomly selected to represent the high and low water fluoride areas respectively. Seguin Form Board Test was used to assess the intelligence quotient (IQ) level of children. Descriptive statistics and independent sample t-test was used for analysis. RESULTS: Mean scores for average, shortest and total timing category were found to be significantly higher (P<0.05) among children living in Mundra (30.45±4.97) than those living in Bhuj (23.20±6.21). Mean differences at 95% confidence interval for these timings were found to be 7.24, 7.28 and 21.78 respectively. In both the villages, females had lower mean timing scores than males but the difference was not statistically significant (P>0.05). CONCLUSION: Chronic exposure to high levels of fluoride in water was observed to be associated with lower intelligence quotient.
