Current concept of oral health and its potential implications for policy and practice of dental health coverage and insurance: Post COVID-19 measurement
This review paper aims to succinctly discuss the current concept and definition of general and oral-health and its potential implications on policy and practice in regards to the dental health coverage/insurance post COVID-19 pandemic. In general, dental policies and coverage are treatment-oriented, largely focus on curative procedures with some portion for preventive care despite most of dental diseases being largely preventable. There is however still no universal consensus definition of health, leading to mixed-feeling in setting-up priorities and direction for health policy. The FDI-World Dental Federation has then published a new definition of oral-health, highlighting the broader determinants of oral-health and envisioning a discussion on the implications of this definition and, in particular, how to transform the new oral health framework into a policy and practice agenda. In Malaysia, it is predicted there will be increasing demand for public dental coverage post COVID-19, however the government is yet to be ready in fulfilling those needs, leading to worsening oral-health inequalities. The lack of healthcare expenditure with no health social-insurance model reduces the affordability and accessibility of patients to private services. Moreover, such narrow definition of oral-health, as influenced by the previous policies led to a limited coverage for common dental diseases, including oral health-related deformities linked to oral cancer and injuries. These are the major challenges for Malaysia. The government should therefore working in partnership, start subsidising dental fees of private health insurance, focus and integrate disease prevention and health promotion within it, to achieve WHO-goal of universal health coverage
Antibiofilm effect of Theobroma cacao (cacao pod) extract on Aggregatibacter actinomycetemcomitans biofilm in vitro
Successful of periodontal treatment is to eradicate biofilm of bacteria. Aggregatibacter actinomycetemcomitans is a Gram-negative bacterium that have been suggested to be the main causes of periodontal disease. Theobroma cacao (cacao pod) is a medicinal plant that has a broad range of pharmacological effects. The aim of this study was to assess the antibiofilm effect of cacao pod extract against A. actinomycetemcomitans biofilm in vitro. A. actinomycetemcomitans were cultured in Brain Heart Infusion broth. Crystal-violet staining in biofilm assays were used to evaluate the cacao pod extract effect on A. actinomycetemcomitans ATCC 33384 biofilms and 0.2% chlorhexidine-gluconate was used as a positive control. After 24 hours of incubation, the optical density of each well in microtiter plates was measured. The results showed that the biofilm density after incubation with the cacao pod extract was significantly decreased in all concentrations and all incubation times (p<0.05). The most effective concentration for inhibiting biofilm A. actinomycetemcomitans was 100% cacao pod extract and 3 hrs of incubation time (p<0.05) with a 98.9% reduction of biofilm compared to negative control. Cacao pod extract is effective in inhibiting the growth of A. actinomycetemcomitans biofilm
Restoration in primary molars placed by undergraduate dental students: reasons for failures
Dental caries is one of the most common chronic childhood diseases and highly prevalent in the world. The commonest treatment procedure for dental caries is a dental restoration which aims to retain the tooth. The survival of restoration depends on the factors associated with restorative materials, patients or operators. Thus, this study aimed to determine the reasons for the failure of restoration in posterior primary teeth performed by undergraduate dental students. A total number of 32 patients aged from 5 to 12 years old were included in this study. Overall, 115 primary molar restorations were assessed clinically using the modified United States Public Health Service Ryge criteria. The O’Leary plaque score was used to evaluate the oral hygiene status of all patients. Then, the data was analysed using the Kaplan-Meier survival curves with log-rank test and Cox regression analysis. 43 (37.4 %) restorations failed with 62.1 % for glass ionomer cement and 36.4 % for composite restorations. Marginal adaptation (62.8 %) is the commonest cause of failure. 76.7% of failure restoration was in patients with poor oral hygiene, and it showed a significant difference compared to patients with moderate and good oral hygiene (p = 0.014). Thus, it was concluded that the type of restorative material and oral hygiene status contributed to the failure of restoration placed in primary molar restorations with failure restoration may occur 2.6 times more in poor oral hygiene patients
Dental anxiety among Wisma Lincoln University College community
Dental anxiety is common among people of all ages, which results in delay and avoidance of dental visit and eventually deterioration of oral health. The aim of this study is to assess the dental anxiety level among the community in Wisma Lincoln University College. A cross-sectional study was carried out from April to December 2018. A total of 186 participants were included in this study. The Modified Dental Anxiety Scale (MDAS) was used to assess participants’ dental anxiety level. The prevalence of participants with severe anxiety level was 16.7% (n=31), with Indian female being the highest number (n=6, 20%). Participants felt most anxious if they were to receive a local anesthetic injection, with a mean score of 2.04 for male and 3.76 for female. With regards to the aspects of dental treatment that make participants anxious, 74.7% (n=139) of the participants would feel anxious about extraction, followed by pain arising from treatment (63.4%, n=118) and fear of injury caused by dental instrument (60.8%, n=113). In conclusion, 16.7% of the community in Wisma Lincoln University College were highly anxious, with Indian female being most anxious (20%).
The use of bioceramic root canal sealers for obturation of the root canal system: A review
The use of bioceramic root canal sealers in endodontics is a promising approach because of the advantages such as improved flow properties, biocompatible and could promote the formation of hard tissue. Due to the recent technology and limited scientific evidence, the effectiveness of bioceramic root canal sealers remains unclear. This article focuses on the physicochemical properties, biocompatibility, biomineralisation, retreatability, 3D obturation and current practice of using bioceramic root canal sealers. The relevant articles for this review were searched manually from Google Scholar and PubMed using keywords ‘bioceramic root filling material AND endodontics’, ‘bioceramic root canal sealers AND endodontics’, ‘cytotoxicity AND bioceramic root canal sealers’, ‘bioceramic root canal sealers AND physicochemical properties’, ‘biomineralisation AND bioceramic root canal sealers’ and ‘retreatment efficacy AND bioceramic root filling materials’. Since the clinical data concerning the obturation with bioceramic root canal sealers is lacking, the selection of materials should be made based on the available scientific evidence, individual cases, material availability and operator’s preference
Endodontic-orthodontic interrelationship: a review.
The endodontic-orthodontic interface is not well understood due to the limited scientific literature on the topic. This article aims to provide an overview of the orthodontic treatment and the risk of root resorption, the effects of orthodontic tooth movement on dental pulp and endodontically treated teeth, the role of orthodontics in endodontic-restorative treatment planning, and interdisciplinary patient management. Articles published in English from 1982 to 2021 were searched manually from google scholar using keywords ‘endodontic-orthodontic interface’ and ‘endodontic-orthodontic interrelationship’. Another search engine was MEDLINE/PubMed database using keywords ‘endodontics AND orthodontics’, ‘orthodontic tooth movement AND dental pulp’, 'orthodontic tooth movement AND endodontic treatment' and ‘orthodontics AND dental trauma’. Other relevant articles were obtained from the references of the selected papers. Alterations to the dental pulp following orthodontic tooth movement can be histologic and/or cell biological reactions as well as the increased response threshold to pulp sensibility tests. However, the occurrence of root resorption is complex and multifactorial, and can be linked to individual variation, genetic predisposition and orthodontic treatment-related factors. Endodontically treated teeth can move as readily and respond similarly to orthodontic forces as vital teeth, however with inadequate endodontic treatment, the risk of apical inflammation and bone destruction following orthodontic tooth movement is increased. Dental treatment that involves endodontic and orthodontic specialities should be carefully planned according to the individual case, taking into consideration the skills and experience of the clinicians while applying interdisciplinary patient management and available scientific data
Perceived stressors of undergraduate dental students at an Australasian dental school
The purpose of this study was to identify the perceived stressors of Bachelor of Dental Surgery (BDS) students at a prominent Australasian dental school using the Dental Environment Stress (DES) questionnaire. All BDS students were emailed a modified version of the DES questionnaire. The questionnaire consisted of forty questions: seven collecting demographic information, one free text question and thirty-two items related to various sources of stress, grouped into four subscales: 1) Academic 2) Clinical and patient related 3) Environmental and 4) Personal. Students were asked to rate the items on a five-point Likert-type scale ranging from not at all stressful (1) to extremely stressful (5). Of the 314 students emailed, 165 responded to the survey (52.5% response rate). The academic subscale had the highest self-reported mean stress score (3.09 ± 0.68 (SD)); compared with the clinical (2.71 ± 0.77), environmental (2.40 ± 0.77) and personal (2.37 ± 0.68) subscales. There was a statistically significant difference (p<0.05) in self-perceived clinic related stress levels between male and female students, with female students reporting more stress. There was also a statistically significant difference in self-perceived environmental stress between second- and third-year students (p=0.037), and in perceived personal stress between students based on their English language status (p=0.034). These findings can enable identification of students who might be at higher risk of stress to ensure support is provided for them; specifically, female students and students in their third year. Results also indicate the need to develop interventions to help all students with academic stressors
Resin infiltration technique as minimal invasive approach towards mild to moderate dental fluorosis in an adolescent: a case report
Dental fluorosis can be defined as a developmental condition that affects dental hard tissue, mainly enamel characterised with white or yellowish lesions due to excessive fluoride exposure. Fluorosis can have a major impact on the appearance, structure and shape of the tooth which posed a significant aesthetic concern to individuals having this condition. There are several treatments recommended in treating dental fluorosis depending on the severity of the disease itself ranging from tooth bleaching to prosthetic crowns in severe cases. This case report describes the use of resin infiltration technique on a patient with mild to moderate severity of dental fluorosis of the upper anterior teeth which produce an acceptable improvement of the appearance of the affected tooth. Resin infiltration technique in this case provided a conservative and inexpensive approach in treating mild to moderate dental fluorosis for the patient, improving the aesthetic without significant loss of tooth structure
Scientific research misconducts : An overview
Research misconduct is defined as fabrication, falsification, or plagiarism in proposing, performing, or reviewing research, or in reporting research results (Anderson, 2013; Breen, 2016; Resnik, 2019). It can occur at many stages of the research process. These include during proposal preparation, data collection, analysis and publication (Amin et al., 2012). The previous studies reported that 2,047 articles were retracted from PubMed in May 2012, with 67% of the articles due to misconduct (Dal-Ré et al., 2020). Besides, the percentage of retracted papers in the year of 2012 were reported to increase by 10-fold compared to the total articles retracted in 1975 (Fang et al., 2012). According to Liu and Chen (2018), the data from Retraction Watch on the 31st July 2017 revealed that the US, China, Germany, Japan and India were the top six countries that had articles retracted.
