RESUMO
AIM: To evaluate the systematic reviews assessing the effectiveness of any type of school-based oral health programs in children and adolescents. METHODOLOGY: A two-staged search strategy comprising electronic databases and registries based on systematic reviews was employed to evaluate the effectiveness of school-based interventions. The quality assessment of the systematic reviews was carried out using the Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR-2) tool. The Corrected Covered Area was used to evaluate the degree of overlap. RESULTS: Nine reviews were included in this umbrella review. The Critical Covered Area reported moderate overlap (5.70%) among the primary studies. The assessment of risk of bias revealed one study with a high level confidence; one with moderate whereas all other studies with critically low confidence. Inconclusive evidence related to improvements in dental caries and gingival status was reported whereas, plaque status improved in a major proportion of the reviews. Knowledge, attitude, and behavior significantly increased in students receiving educational interventions when compared to those receiving usual care. CONCLUSIONS: The evidence points to the positive impact of these interventions in behavioral changes and clinical outcomes only on a short term basis. There is a need for long-term follow-up studies to substantiate the outcomes of these interventions.
RESUMO
OBJECTIVE: This systematic review was conducted to explore the factors influencing access to oral health services and to identify and examine the strategies to improve the access. MATERIALS AND METHODS: PubMed, Scopus and Embase databases were searched. Studies except editorials reported in English regardless of the study design were included. Risk of Bias assessment was carried out using Agency for Healthcare Research and Quality, Newcastle Ottawa Scale and The Joanna Briggs Institute tool for cross-sectional, case-control and cohort and qualitative studies, respectively. RESULTS: In total, 11,372 records were initially identified, eventually leading to 12 relevant publications to be included in the review. Individuals valued oral health but found it difficult to access oral health services. Dental care was mainly accessed during emergencies and participants felt apprehensive in visiting dentists. Caregiver's and dentist's perspective was also reported. CONCLUSION: There is a need for provision of education, training and increasing awareness on dental hygiene and annual dental checkups to improve access.

AIM: To systematically review the evidence from published literature about the impact of war on oral health among children and adults. METHODOLOGY: The electronic search was carried out in the following databases Pubmed, Cochrane, Scopus, Embase, Google Scholar. In vitro studies, cross-sectional, case control studies, and randomized controlled trials conducted during the war time were included. Cross-sectional and case control studies were assessed based on the Newcastle-Ottawa Scale, whereas randomized controlled trials were assessed based on the ROBINS-I tool. In-vitro studies included in this review were assessed using the United States national toxicology program tool. RESULTS: The search strategy yielded a total of 5126 articles and finally 21 articles were included in the review. The influence of war on oral health was categorized among both the children and adult population. A total of 14 studies were carried out in children whereas the remaining seven studies were carried out in adults. A decrease in dental caries was observed in more war-prone areas due to the limited availability of carbohydrates and sugar. Severe periodontal disease in the adult population, mainly due to less availability of food and diminished oral hygiene habits, was also reported. CONCLUSIONS: This review underscores the multifaceted impact of war on oral health, revealing a notable prevalence of periodontal problems, craniofacial injuries and varying rates of dental caries across affected populations.
RESUMO
OBJECTIVE: Importance of oral health during pregnancy has been well reported. To prevent the occurrence of oral diseases and maintenance of oral health, a number of guidelines have been developed by different organizations. However, despite numerous efforts in development of these guidelines, a critical evaluation of the quality of guidelines has not been carried out. Thus, we aimed to perform a systematic review to assess the quality of guidelines on oral health care during pregnancy. METHODS: PubMed, Embase, Scopus and Cochrane Databases were electronically searched in March 2024. STUDY ELIGIBILITY CRITERIA: We included guidelines that were carried out within last 10 years and focused on oral health during pregnancy were included in this review. Guidelines focused for both oral health professionals and non-oral health professionals were included in this review. The assessment of the guidelines in this review was carried out using the AGREE II instrument. The four appraisers who carried out the assessment comprised of a gynecologists, a dental practioners, a public health expert and a dental public health professional. The instrument comprises of 23 key items within six domains and two additional global rating items. RESULTS: We included eight guidelines in this review. The AGREE II showed two domains with mean score of more than 70% scores across the guidelines. A comparative evaluation of all the guidelines revealed consistently higher scores in scope and purpose (81.71 + 6.3) and clarity of presentation (71.61 + 11.7). Lowest mean scores were reported for editorial independence (47.87 + 7.21) followed by rigour of development (56.19 + 16.97), applicability (57.50 + 13.7) and stakeholder involvement domain (63.17 + 14.31). CONCLUSION: Although many guidelines have demonstrated adherence to systematic methodologies, there still exists a scope of improvement in domains such as editorial independence, rigour of development, applicability and stakeholder involvement. Addressing these shortcomings is essential for promoting evidence-based oral health care practices and improving maternal and neonatal health outcomes.
RESUMO
AIM. The aim of this study was to train dentists on the different oral hygiene measures to be followed by COVID-19 patients via Webinar and Information Education Communication (IEC) Materials and compare the effectiveness of both. METHODOLOGY. A total of 100 dental professionals were included by non-probability convenience sampling. Webinar and IEC Materials on oral hygiene measures, oral symptoms, and management strategies during COVID-19 were created and training was conducted for all dental professionals who registered themselves. An online version of the self-administered questionnaire (English) was created on the official Edantseva website and circulated to all the registered participants to obtain the pre and post-training data. RESULTS. Out of the total 80 participants in the Webinar group, 47 were females and 33 were males. Comparing the mean total scores obtained by the participants in the webinar and IEC groups in the pre and post-test showed that there is a significant difference in the scores obtained by the participants in the two groups in the pre and post-test (p<0.01). CONCLUSION. Educating dentists via IEC Materials was effective in improving their knowledge regarding oral health management during the COVID-19 pandemic. IEC materials being handy and referable at any time was found to be more effective.

This systematic review aims to determine the association between the consumption of sugar-sweetened beverages (SSBs) and periodontal disease. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed to conduct a literature search on five electronic databases till January 2022. Systemically healthy individuals consuming SSBs and presenting periodontal disease (gingivitis/periodontitis) were included. The modified Newcastle-Ottawa Scale and the Grading of Recommendation Assessment Development and Evaluation criteria were respectively used to assess the risk of bias and the evidence's quality. Of the 1303 eligible records identified in the initial search, ten studies (nine cross-sectional and one case-control) were selected for the final review. Among the included articles, five reported SSBs intake in the form of carbonated soft drinks, two as sugary drinks, two as soft drinks, and one as coffee with added sugar. Four studies reported gingivitis as an outcome, while the remaining six studies reported periodontitis using validated indices. The included studies were of medium to high quality. Consumption of SSBs may increase gingival bleeding, thereby gingivitis and the risk of periodontitis. Intake of added sugars like SSBs should be considered as a potential factor during gingival/periodontal risk assessment. Further studies are warranted to establish additional evidence of association.

BACKGROUND: COVID -19 pandemic has imposed multiple questions and consideration in the minds of the patients and dental professionals. The understanding of patient's perceptions and dental services utilization can aid in modifying the pre-existing dental practices. The aim of the present study was to assess the awareness, perceptions and dental services utilization by patients visiting a tertiary care centre during COVID-19. METHODOLOGY: A cross-sectional study on 437 patients was carried using a validated questionnaire consisting of 22 questions on three domains. Strict sterilization protocol and infection control measures were practiced to avoid any contact between the investigator and the patient. RESULTS: Patients were aware of COVID -19 pandemic and were willing (76.7%) to inculcate preventive practices even post-pandemic. Concerns regarding the spread of infection (37.3%) and hygiene/cleanliness (28.6%) were most commonly reported. Patients visited the dental centre primarily for emergency management and preferred their queries being solved on the phone. CONCLUSION: Patients had a positive outlook towards visiting the dental centre for treatment in the near future and did not report any anxiety before visiting a dental centre.

OBJECTIVES: Most studies focusing on oral hygiene status in hearing impaired individuals are cross-sectional and focus on specific populations. A comprehensive literature search and evidence-based analysis was carried out to assess the oral hygiene status in this special group of population. METHODS: Searches were conducted in four databases with no restriction on publication date. Cross-sectional and comparative cross-sectional studies assessing the oral hygiene status and periodontal status of hearing impaired individuals using standardized evaluation criteria were included. Study selection, data extraction, and assessment of bias were carried out by four reviewers and oral hygiene, plaque, and gingival status were assessed. The risk of bias assessment was carried out by New Castle Ottawa Quality Assessment Scale. 29 relevant publications that fulfilled the eligibility criteria were included in the systematic review whereas six studies each assessing oral hygiene and plaque status and five studies evaluating the gingival status were included in the Meta-analysis. RESULTS: Eight thousand eight hundred and ninety (8890) potentially relevant references were identified in the systematic literature search. The overall analysis of the included studies revealed a mean oral hygiene index score of 1.60 (95% CI 0.91-2.30), Gingival Index scores 1.27 (95% CI 1.02-1.51), and Plaque Index score 0.99 (95% CI 0.75-2.30) among the hearing impaired individuals. CONCLUSION: The present study reported fair oral hygiene, fair plaque status, and moderate gingivitis among the hearing impaired individuals.

BACKGROUND: Smokeless tobacco (SLT) use is positively associated with oral, oesophageal, and pancreatic cancers. The tobacco dentifrice is a type of SLT which is applied to the teeth and gums. It is available in different forms which include mishri, gul/gulmanjan, gudhaku, snuff, red tooth powder, and creamy snuff. This qualitative study aims to explore the opinions and beliefs associated with the harmful effects of tobacco dentifrice use. METHODOLOGY: Thirty in-depth interviews were conducted among tobacco dentifrice users visiting a dental hospital. The data were coded and analysed using thematic analysis in ATLAS.ti software 8. RESULTS: A total of 11 codes and six categories were generated which comprised of the reason for the initiation, awareness of health effects, perception of oral tobacco application, perception of quitting, the reason for continued use, and use in society. Family, peers, access to the product, curiosity were important factors to initiate the tobacco dentifrice use. Participants believed in the myth that tobacco dentifrice was beneficial for the teeth, gums, and bowel movements. The participants considered tobacco dentifrice to be less harmful than other forms of tobacco. However, some participants were aware of its adverse effects on health and have tried to quit in the past. None of the participants had taken any professional help for quitting. CONCLUSION: There were strong beliefs and myths among the participants that tobacco dentifrice was beneficial for oral and general health. There is a need to create awareness and improve the standard of the health warning of such products.

The deteriorated oral hygiene in visually impaired individuals has paved way for the emergence of different interventions for oral health promotion. This systematic review assessed the effectiveness of different interventions in improving the oral hygiene of visually impaired individuals. A search using PubMed, Cochrane Library, Science Direct, Wiley online and Scopus search engines published before September 2020 was carried out. Dental plaque, gingival status, oral hygiene status and improvement in knowledge status were assessed. The systematic review consisted of nine studies fulfilling the eligibility criteria and seven studies after checking for quality of evidence. The interventions significantly improved plaque scores, gingival and oral hygiene status, as well as the knowledge of visually impaired individuals. The combination of two or more interventions was reported to be better in improving oral health when compared with the individual interventional techniques for visually impaired individuals.

INTRODUCTION: The classification of odontogenic tumors has been revised from time to time in order to provide unified terminology. This reclassification had considerable impact on their prevalence and frequency distribution. OBJECTIVES: This study was aimed to emphasize impact of changing classification systems on prevalence and relative frequency of odontogenic tumors. The secondary objective was to analyze demographics of various histological types of odontogenic tumors in comparison to published literature. Review of Indian studies (1992-2020) elaborating frequency of odontogenic tumors is summarized in the end. METHODS: This was a hospital-based retrospective study wherein case files of odontogenic tumors diagnosed from 1990 to 2019 period were retrieved. The classification system used originally at the time of diagnosis was retained and prevalence of odontogenic tumors in three different periods (1990-2004, 2005-2016 and 2017-2019) was compared. Further, prevalence, frequency distribution and demographics of all these tumors (1990-2019) were analyzed using latest World Health Organization 2017 classification. RESULTS: A total of 345 odontogenic tumors was diagnosed as per World Health Organization 2017 system of classification from 1990 to 2019. 96.81% tumors were benign and 3.81% constituted malignant odontogenic tumors. However, there was marked increase in prevalence of odontogenic tumors in 2005-2016 (6.2%) period as compared to 1990-2004 (3.87%) and 2017-2019 (3.47%). Ameloblastoma remained the most common tumor in three different periods, whereas keratocystic odontogenic tumor became second commonest tumor in 2005-2016 as compared to odontoma in 1990-2004 and adenomatoid odontogenic tumor in 2017-2019. CONCLUSIONS: The continuous evolving systems of classification may partly be responsible for inconsistency in odontogenic tumors, with inclusion of keratocystic odontogenic tumor,and has marked impact on prevalence and frequency distribution of odontogenic tumors. The geographical variations in demographics of odontogenic tumors might reflect genetic and environment influence; however it requires elucidation by further studies.

BACKGROUND: With the emergence of the WHO Framework Convention on Tobacco Control, globally the use of tobacco has decreased notably, although, it still requires efforts at individual, organizational, community level to decrease the rate further. Dental professionals are at an excellent position to provide tobacco cessation counselling and interventions, however, it is not practiced much due to lack of training and lack of knowledge. Therefore, this systematic review was conducted to assess the global status of knowledge, attitude and practice on tobacco cessation interventions among dental professionals. MATERIALS AND METHOD: A systematic search of 6 databases with no language restriction since 2000 was undertaken. Studies were included if they assessed knowledge, attitude and practice on tobacco cessation interventions among dental professionals using a validated or prevalidated tool. The data obtained for assessment of knowledge, attitude, practice, curriculum and barriers were represented through heatmaps. Quality assessment of the studies was done using Newcastle Ottawa scale. RESULTS: Fifty six studies were included in this systematic review. Majority of the studies were found to be of moderate quality. Knowledge regarding the tobacco cessation interventions was more theoretical than practical. All the studies showed a favorable attitude among dental professionals towards tobacco cessation intervention. CONCLUSION: The included studies lack homogeneity in assessing knowledge, attitude and practice on tobacco cessation interventions. The development and validation of a standardized questionnaire to assess knowledge, attitude and practice on tobacco cessation interventions could be a potentially effective way to uniformly gather data on the subject.
RESUMO
INTRODUCTION: In India every year, an estimated 1 million people die from tobacco-related illnesses, which could have been avoided by stopping tobacco use. This study aimed to determine the tobacco dependence and perceptions about tobacco cessation among the patients attending a tertiary care dental hospital. METHODS: A mixed-methods study was conducted among the individuals visiting the dental hospital. Self-administered questionnaires were used to record quantitative data on the current and past tobacco history, tobacco dependence, and quit attempts. Face-to-face interviews were conducted to collect qualitative data on the perceptions on tobacco quitting. RESULTS: About 52% of participants had made an attempt to quit tobacco in the past. The majority of the smokers (82.7%), smokeless tobacco (SLT) users (71.3%), and dual users (83.1%) reported being in the contemplation phase of quitting tobacco. SLT users (12.3%) reported to have taken action in the past to quit tobacco compared to 9.6% smokers, and 1.4% of dual users. Doctors advise, motivation from family and friends motivated the participants to quit tobacco. The risk perception of tobacco use was reported as death, cancer, dental diseases, systemic diseases like chest congestion, cough, tuberculosis, lung cancer, and general body weakness. However, some of the participants were unaware of the methods to quit tobacco, some had misconceptions that shifting to other forms of tobacco and alcohol could help in quitting, and considered SLT to be less harmful than smoking forms. CONCLUSION: Majority of the participants were willing to quit tobacco and had taken measures to quit in the past. There is a need to increase the awareness among the tobacco users about the health risk of tobacco use, and motivate them to utilize the existing cessation services available.

INTRODUCTION: The purpose of this study is to evaluate the effect of change in vertical placement of bracket and effect of tooth morphology on stress developed on periodontal ligament with the help of three dimensional finite element modeling. METHODS: A three-dimensional model of the maxillary bone, maxillary right central incisor, lateral incisor and canine was designed based on the average dimensions of the anatomy and morphology given by Wheeler's and standard edgewise bracket with Slot of 0.022â³ X 0.028â³ inch was designed using the finite element method. Brackets were placed on each tooth, on the mentioned labial surface at variable distances from the cusp tip, and a full size archwire was virtually engaged into the bracket, then optimum orthodontic load of 2N is applied and PDL stress were calculated. RESULTS: The lowest stress values were measured as bracket position changes from crest of teeth to the apical direction. By displacing the bracket gingivally from 1.5 to 6 mm, a 16.2% decrease in stress level for central incisor, for lateral incisor the stress level decrease by 25.8% and for canine the stress level decrease by 21.6% thus our study confirms that variation in vertical bracket position results in change in resultant stress in PDL. CONCLUSION: It can be concluded that the variation in the vertical position of the bracket osn different tooth can have an important effect on the stresses developed in the PDL.
RESUMO
Law influences every aspect of human activity, and dentistry in this regard is no exception. Ethical standards of the dental profession are seeing a steady decline, altruistic concepts being overridden by a market driven system. A deficient knowledge regarding the medico-legal aspects halts the effective implementation and delivery of efficient services. The review thus provides an overview of ethical standards, consents and their types, negligence,, determination of negligence, liabilities of dental practitioners and solicitors in dental practices, which comprehensively form an integral part of the medico-legal aspect of dental practice.
RESUMO
BACKGROUND AND AIM: To determine the effect of pre-cooling injection site on pain perception in patients attending a dental camp at lifeline express, Habibganj. METHODS: A split mouth interventional study assessed the effect of pre cooling the injection site in patients (n=33) requiring bilateral buccal infiltration prior to extraction. One side of the patient's mouth received the intervention after the injection site was pre cooled with ice for 3 minutes along with topical Lidocaine, while the other mouth side of the same patient received only topical Lidocaine and served as control group. A structured proforma assessed the demographic characteristics and risk factors that influence pain perception in patients. Mann-Whitney U tests and Wicoxon rank sum test were used for statistical analysis. Statistical significance was defined at P<0.05. RESULTS: The results revealed a significant difference in pain perception between control and intervention group as assessed using both Heft-Parker Visual Analog Scale (median score 3.0 and 1.0) and Sound Eye Motor scale (median score=1.0 and 0.0) (P<0.01). For both the scales the assessed and self reported variables Gender, Location, Chief Complaint, Region and Arch were found to be statistically significant. CONCLUSION: Pre cooling injection site reduced pain perception in patients.

Resumo Introdução A classificação dos tumores odontogênicos é revisada de tempos em tempos para fornecer uma terminologia unificada. Essas revisões tiveram um impacto considerável na prevalência e distribuição da frequência desses tumores. Objetivo Enfatizar o impacto da mudança dos sistemas de classificação na prevalência e frequência relativa dos tumores odontogênicos. O objetivo secundário foi analisar os dados demográficos de vários tipos histológicos de tumores odontogênicos em comparação com a literatura publicada. A revisão dos estudos indianos (1992-2020) sobre a frequência dos tumores odontogênicos é resumida no fim. Método Este foi um estudo retrospectivo com base em registro hospitalar de casos de tumores odontogênicos diagnosticados de 1990‐2019 que foram revisados. O sistema de classificação usado originalmente no momento do diagnóstico foi mantido e a prevalência de tumores odontogênicos em três períodos (1990-2004, 2005-2016 e 2017-2019) foi comparada. Além disso, a prevalência, a distribuição da frequência e os dados demográficos de todos esses tumores (1990-2019) foram analisados com a classificação mais recente da OMS de 2017. Resultados Foram diagnosticados 345 tumores odontogênicos de acordo com o sistema de classificação da OMS (2017) de 1990-2019. A ocorrência de tumores odontogênicos benignos e malignos foi de 96,81% e 3,81%, respectivamente. Contudo, houve um aumento acentuado na prevalência de tumores odontogênicos de 2005‐2016 (6,2%), comparado aos períodos de 1990‐2004 (3,87%) e 2017‐2019 (3,47%). O ameloblastoma permaneceu como o tumor mais comum em três períodos, enquanto o tumor odontogênico ceratocístico passou a ser o segundo tumor mais comum em 2005‐2016, comparado ao odontoma em 1990‐2004 e ao tumor odontogênico adenomatoide em 2017‐2019. Conclusões Os sistemas de classificação em evolução contínua podem, em parte, atribuir uma inconsistência à classificação dos tumores odontogênicos com a inclusão do tumor odontogênico ceratocístico e causar um impacto marcante na prevalência e distribuição da frequência dos tumores odontogênicos. As variações geográficas na demografia dos tumores odontogênicos podem refletir influências genéticas e ambientais, mas requerem elucidação por estudos futuros.
RESUMO
BACKGROUND AND AIMS: To assess and compare the effects of different oral hygiene procedures on the reduction of morning bad breath, plaque and gingival status in healthy subjects. METHODS: A four step cross-over trial was performed on 32 study subjects. They were allocated into four groups: Group I: tooth brushing; Group II: tooth brushing and tongue scraping; Group III: tooth brushing and mouth washing; and Group IV: tooth brushing, tongue scraping and use of mouthwash. A washout interval of 7 days was employed. At the beginning and at the end of all intervention periods, breath score was measured by hand held sulfide monitor (Breath Alert) at four time intervals. The Plaque and Gingival status was evaluated using Plaque and Gingival Index. RESULTS: The highest reduction in mean breath score (2.12±0.65), plaque score (0.75±0.47) and gingival score (0.67±0.41) were found in the Group IV followed by Group II and Group III. A significant positive correlation was observed between plaque scores and gingival scores before intervention (r=0.443; p value<0.001) and after intervention (r=0.846; p value<0.001). CONCLUSION: The study findings suggest that mechanical aids in conjunction with chemical regimens are considered as the most effective method for reducing the morning bad breath in healthy subjects and should be incorporated in daily oral hygiene practices.
