Practical applications of teledentistry during the Covid-19 pandemic in ASEAN member states - a systematic review.

OBJECTIVE: The objective of this review is to determine the utilisation and adoption of teledentistry based solutions and technologies during the Covid-19 Pandemic in the Asean region. BACKGROUND: Teledentistry is a branch of telemedicine that has rapidly advanced in the last few years and has the potential to provide solutions to oral health problems of patients and locations that do not have prompt and immediate access to a dentist or dental services. The Covid-19 has increased the adaption of all digital health technologies and teledentistry is no exception. METHODOLOGY: The study utilized online databases such as Pubmed (Medline), Scopus (Embase) and CINAHL for the purpose of document search. Newcastle Ottawa (NOS) scale was used to determine the quality of the studies included in our systematic review. PRISMA guidelines were used as the criteria for reporting items in the systematic review. RESULTS: A total of 1297 documents were found after applying the search criteria and the keywords for the selected study. After applying the Prisma guidelines, removal of duplicates and irrelevant entries, 10 studies that were conducted during the Covid-19 pandemic were selected, fitting the inclusion criteria. All the studies included were evaluated for quality and risk of bias through the Newcastle Ottawa scale. Only high-quality studies were included for the final review. CONCLUSION: Teledentistry is a cost-effective solution to screen, diagnose and treat dental patients from a distance. Teledentistry also has the potential to continue seamless continuation of dental education to dental students, during disruptive and non-disruptive periods. ASEAN countries should fully utilise the potential of teledentistry, however sound and effective legislation would be the key first step to achieving that potential.

Breaking Down Barriers and Paving the Way for Blockchain Adoption in Dentistry.

Blockchain technology can potentially transform the dentistry sector by facilitating safe communication between dental practitioners and offering secure and efficient administration of patient information. Nevertheless, using this technology in dentistry confronts various barriers, including regulatory and legal obstacles, a lack of technical skills, and a lack of standardization. To overcome these challenges, dental practitioners, industry stakeholders, and regulators must work together to develop a legislative framework that encourages the use of blockchain technology in dentistry. Moreover, education and training programs must equip dental practitioners with the skills and expertise to properly incorporate and use blockchain technology. The use of blockchain technology in dentistry has the potential to greatly improve patient outcomes while also increasing the efficiency and security of the dental business.

Monkeypox resurgence and its implications for Dentistry - A scoping review.

INTRODUCTION: Monkeypox caused by the Monkeypox virus, a member of the Orthopoxvirus genus, is currently considered a major concern among healthcare authorities due to its high transmissibility rate. Currently, no specific treatment is available for this disease, due to which healthcare professionals, specifically Dentists, are required to look out for symptoms at early stages to prevent its spread. OBJECTIVE: To analyze the role of dentists in identifying Monkeypox cases and limiting its spread. METHODS: We conducted a scoping review on monkeypox and its oral manifestation. PRISMA protocols were observed in data collection. The relevant literature search was conducted in relevant databases like PubMed, Scopus, Web of Science, Embase, CINAHL, and Google Scholar. Relevant articles related to Monkeypox, and Dentistry were included in the final review. Articles published from March 2022- September 2022 were included in the review. Keywords and Mesh words related to monkeypox, and dentistry were used as part of the search strategy. RESULTS: A total of 1881 articles were reviewed, among which 7 articles were included. Dentists were strongly advised to be on high alert for Monkeypox symptoms due to their close contact with patients. Around 70% of Monkeypox cases reported oral lesions at early stages, which requires a differential diagnosis from other oral lesions. Considering this, dentists should be well-versed in this new and emerging threat. CONCLUSION: Although dentists have been shown to play an important role in the treatment of monkeypox, there is insufficient data available. More research on dentistry and monkeypox will be needed in the near future.

Systematic review on the current state of disaster preparation Simulation Exercises (SimEx).

INTRODUCTION: The simulation exercise (SimEx) simulates an emergency in which an elaboration or description of the response is applied. The purpose of these exercises is to validate and improve plans, procedures, and systems for responding to all hazards. The purpose of this study was to review disaster preparation exercises conducted by various national, non-government, and academic institutions. METHODOLOGY: Several databases, including PubMed (Medline), Cumulative Index to Nursing and Allied Health Literature (CINAHL), BioMed Central, and Google Scholar, were used to review the literature. Information was retrieved using Medical Subject Headings (MeSH) and documents were selected according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). To assess the quality of the selected articles, the Newcastle-Ottawa Scale (NOS) technique was utilized. RESULTS: A total of 29 papers were selected for final review based on PRISMA guidelines and the NOS quality assessment. Studies have shown that many forms of SimEx commonly used in disaster management including tabletop exercises, functional exercises, and full-scale exercises have their benefits and limitations. There is no doubt that SimEx is an excellent tool for improving disaster planning and response. It is still necessary to give SimEx programs a more rigorous evaluation and to standardize the processes more thoroughly. CONCLUSIONS: Drills and training can be improved for disaster management, which will enable medical professionals to face the challenges of disaster management in the 21st century.

Effects of Riboflavin Collagen Crosslinker on Dentin Adhesive Bonding Efficiency: A Systematic Review and Meta-Analysis.

The aim of this study was to evaluate published data regarding riboflavin (RF) as a cross-linker for improved adhesive bond strength to dentin and to analyze previous studies for optimal concentration of riboflavin range suitable for dentin bond. Saliva and distilled water were used as storage media and aging time was 24 h and 6 months. Results of meta-analysis were synthesized using a statistical method of inverse variance in random effects with a 95% Confidence Interval (CI). Cochrane review manager 5.4.1 was used to determine results of the meta-analysis. In total, 3172 articles were found from search databases "PubMed", "Scopus", and "Google Scholar". Six of the fifteen studies were eligible for meta-analysis. Micro tensile strength shows significant improvement with the addition of riboflavin (p < 0.05) compared to without the addition of riboflavin from with 95% CI. A significant difference has been found in micro tensile bond strength between use of the riboflavin cross-linker and without use of the riboflavin crosslinker in the dentin adhesive system. With a 95% confidence interval (CI), the I2 for micro tensile strength was 89% with strong heterogeneity, Chi2 = 44.76, df = 5 (p < 0.00001), and overall effect size is Z = 2.22 (p = 0.03) after immediate aging. Chiang et al. 2013 shows maximum mean differences which is 38.50 [17.93-59.07]. After 6 months of aging in distilled water or artificial saliva micro tensile bond strength has been increased with the addition of riboflavin (p < 0.05). It can be clearly seen that pooled effect and 95% CI did not cross the line of no effect. With a 95% confidence interval (CI), the I2 for micro tensile strength was 96% with strong heterogeneity, Chi2 = 117.56, df = 5 (p < 0.00001), and overall effect size is Z = 2.30 (p = 0.02). Subgroup analysis proved a similar effect of distilled water and artificial saliva as storage media on micro tensile bond strength after incorporating riboflavin as a collagen crosslinker. An artificial saliva aged forest plot also showed considerable heterogeneity with I2 = 96%; Tau2 = 257.32; Chi2 = 94.37; df = 2 (p < 0.00001); test for overall effect, Z = 1.06 (p = 0.29). Riboflavin prior to or with bonding is recommended to improve the bonding of different adhesive systems.

In vitro evaluation of the color stability and surface roughness of a new composite flow.

Background: The aim of this study was to evaluate the color stability and the surface roughness of a bulk-fill composite flow (SDR® Plus) by comparison to an ORMOCER-based composite (Ceram.x® Universal SphereTEC™) in order to confirm the validity of using SDR® Plus in the anterior region and to allow the prediction of its long-term results. Material and Methods: 35 composite specimens of the same shade (A2), thickness (2mm) and shape of both types of composite were prepared. The specimens were cured and polished according to the manufacturer's instructions. The initial shade of the specimens was measured using a calibrated EasyShade spectrophotometer. The initial surface roughness of the specimens was measured by AFM. Afterwards, the specimens were subjected to an accelerated aging procedure through thermo-cycling, a coffee stain challenge and brushing to simulate two years in the oral environment. The shade and surface roughness of the specimens were measured again after the accelerated aging procedure. Results: The mean ΔE was significantly larger than 3.368 in Ceram.x® group (-p-value<0.001) and SDR® Plus group (-p-value<0.001). The mean surface roughness has significantly increased for both groups after aging with no significant difference between the two groups. It however remained clinically acceptable. Conclusions: SDR® Plus and Ceram.x® showed similar surface roughness when subjected to the same testing conditions. Concerning the color stability, both composites displayed noticeable discoloration, with higher ΔE values registered for Ceram.x®. Key words:Composite resins, spectrophotometry, atomic force microscopy, dental material, resin-based material.

Quantitative Measurements of the Depth of Enamel Demineralization before and after Bleach: An In Vitro Study.

Objective: This study is aimed at determining two main points. First, if the Canary System™ (CS), initially used to assess caries, can measure a decalcification depth of bleached enamel quantitatively, and second, whether or not whitening has a harmful effect on enamel. This device can be considered a useful tool in the clinical assessment of the progression of demineralization after bleaching. Materials and Methods: This study collected sixty human premolars that are in a good state recently extracted for orthodontic reason. To properly disinfect and preserve the premolars, they were stored in a saline solution and later in distilled water for a period of two weeks to allow the premolars to rehydrate. Later, 24 hours before the experiment, the premolars were introduced into a solution of artificial saliva to acquire back their minerals. The mineral content of the teeth was measured by the Canary System™ before bleaching. The teeth were bleached with 30% hydrogen peroxide (fläsh HP 30%), 30 min per week and for 3 consecutive weeks to simulate the conditions of strong bleaching in the clinic. The extent of demineralized enamel was measured by the Canary System™ at three points on the enamel surface of each tooth. The data were averaged for each application of the bleaching product. The demineralization extent of the teeth was measured by the Canary System™ before and after bleaching. The significance level was set at 0.05, and SPSS version 26 was used. The data were analyzed by using Wilcoxon's and Student's tests. Results: Mineral loss occurred after the first bleaching session; the Canary System™ detected a decalcification in the first bleaching session (532 ± 322 µm) compared to the other sessions (p ≤ 0.05), while no significant change was detected between the second and the third sessions (p > 0.05). Conclusion: Based on the findings of the present study, under in vitro conditions, it was possible to measure the demineralization extent of bleached enamel with the Canary System™.

The promise of telemedicine in Pakistan: A systematic review.

BACKGROUND: Telemedicine offers the possibility of provision of medical assistance to remote patients, and it has great potential in developing countries like Pakistan. Telemedicine solves logistical barriers, gives support to weak health systems, and helps to establish worldwide networks of healthcare professionals. Because of the high implementation costs, it is not possible yet to adopt telehealth systems for low- and middle-income nations. OBJECTIVE: To present a revision of region-based telemedical services in Pakistan. METHODS: Libraries such as PubMed (Medline), CINAHL (Cumulative Index to Nursing and Allied Health Literature), Scopus (EMBASE), and Google Scholar were used for document search. Newcastle-Ottawa Scale (NOS) was adopted to conduct study quality. Many of the studies (n-8) included in the review were of high quality as assessed through the Newcastle-Ottawa scale. Selected study characteristics were further analyzed based on different parameters such as publication year, sample size, study design, methods, motivation, and outcomes. RESULTS: Search produced 955 articles and 11 items were ultimately selected to conduct the review. These studies were further characterized as region-based telemedicine implementation. Out of 11, eight studies were conducted in the urban region and three studies were conducted in the rural areas of Pakistan. Many studies produced evidence on telehealth interventions by smartphone services such as SMS, apps, and web-based telemedicine. CONCLUSIONS: Telehealth interventions such as mHealth, eHealth, telemedicine, and telepharmacy in Pakistan were introduced starting from the last two decades. For obtaining the full benefits of these technologies, it is necessary that they but certainly need to become an integral part of Pakistan's current health infrastructure.

Visualization of initial bacterial colonization on dentin using fluorescence activating headlight for fluorescence enhanced theragnosis.

OBJECTIVE: To evaluate accuracy of caries detection and the application-sensitivity of the new Designs for Vision's REVEAL™ utilizing a fluorescence activating headlight for excitation purpose. MATERIALS AND METHODS: REVEAL dental fluorescence loupes and headlight system were used. Occlusal enamel was removed, and mid-coronal dentine was exposed. Carious artificial lesion was created. Streptococcus mutans, Actinomyces naeslundii, and Streptococcus sanguis were used. The assessment was performed using two diagnostic methods: naked eye and Design for Vision Glasses with inter examiner blinding using two calibrated examiners. After 7 days, Raman measurements were made on dentin disc specimens with 785 nm wavelength. The bacterial counts in colony-forming units (CFU) were used to examine the growth kinetics of biofilms. The collagen fibril structure within the discs was performed using Transmission Electron Microscope. Scanning Electron Microscope was used to image samples at various magnifications. FISH was performed with specimens fixed in 4% paraformaldehyde in phosphate-buffered saline. Reproducibility was measured by Cohen kappa scores, values of which range from 0 for less than chance agreement to 1 for almost perfect agreement (p < 0.05). RESULTS: A significant kappa score of 0.706 showing significant reproducibility for the given diagnostic techniques, as all the teeth included in the study were spotted with the lesions. Most bacteria were detected using the CFU technique. The Raman bands scanned across the dentin surface at 960 cm-1 (P-O peak) are assigned to hydroxyapatite phosphate vibrations. FISH identified nearly all stained bacteria as days and time and dental hard tissue had a significant impact on the number of adherent bacteria. Scanning electron micrographs of polished cross sections of demineralized and non-demineralized specimens with perpendicular each tubule orientation (zone of demineralized dentin inset. CONCLUSION: Fluorescent enhanced theragnosis through Reveal vision glasses can ensure constant monitoring and diagnosis of caries progress . This may allow for a better clinical outcome.

A Two-Year Comparative Evaluation of Clinical Performance of a Nanohybrid Composite Resin to a Flowable Composite Resin.

OBJECTIVE: This prospective in vivo study aimed to compare the clinical behavior of a flowable composite resin (Genial Universal Flo, GC) and a nanohybrid universal composite resin (Tetric Evo Ceram, Ivoclar Vivadent) used in Class I and II direct esthetic restorations in posterior teeth. METHODS: A total of 108 Class I and II direct restorations were performed in patients aged between 20 and 60 years. The originality of this study lies in the fact that both materials were placed in pairs, in the same clinical environment (i.e., the same patient and the same type of tooth). The evaluations were performed now of restoration and after 2-weeks, 6-, 12-, and 24-months intervals using clinical examination, clinical photographs, and radiological examination, according to modified USPHS criteria. Statistical analysis was performed using the Fisher exact test and chi-square analysis. RESULTS: At baseline, the universal composite resin showed better esthetic properties such as surface luster, surface staining marginal staining. Both materials regressed significantly over time with no significant difference between groups. CONCLUSIONS: Both flowable and nanohybrid composite resins exhibit acceptable clinical performance. The present 24 months of evaluation of different composites showed that the G-ænial Universal Flo could be an effective esthetic material for posterior restoration. No significant difference between both materials over time concerning surface luster, surface staining, and marginal staining.

Knowledge, Attitudes, and Perceptions of Dental Assistants regarding Dental Asepsis and Sterilization in the Dental Workplace.

MATERIALS AND METHODS: A cross-sectional study was carried out. A 27-item prepilot tested close-ended questionnaire was designed and administered online to collect data on knowledge of asepsis, sterilization, instrument handling, disinfection, hand-hygiene practices, dental practice, age, education, and experience level from March 2020 to June 2020. RESULTS: Out of 70 dental assistants, the majority were aged between 21 and 29 years (44.30%), more than two-thirds (85.41%) of the dental assistants were working in a hospital, while 14.29% were working in private clinics, only 7.1% had a diploma in the dental assistant program, and 74% had more than 2 years of experience in practice. Dental assistants working in private practice (76.30) had a higher mean knowledge scores compared to those working in hospital (74.25), while those with less than 2 years of experience (75.61) had a higher scores compared to those with 2-5 years of experience (73.96). CONCLUSION: Better compliance with recommended infection control and waste management practices is needed for all dental assistants. Continuing education programs targeting such awareness are vital to improve the management of hazardous waste practices among dental assistants.

Teledentistry-based Program to Improve Oral Hygiene Indicators in Rural Pakistan-A Protocol.

AIM: The primary aim of this research protocol is to secure funding to initiate a teledentistry pilot project in order to improve the oral hygiene conditions of the most vulnerable population of rural Sindh in Pakistan, through hands-on training of 1,000 lady health workers by dentists and community dentistry specialists of other colleges led by Jinnah Medical and Dental College. MATERIALS AND METHODS: Training courses on digital health consultation would be given to participating healthcare workers. The trainees would be trained on all aspects of dental hygiene including precautions, tooth brushing techniques, and oral care. During the 2-day-long course, lady health workers will be taught various tooth brushing techniques, as well as basic instructions about oral hygiene and how to address queries of people regarding oral health. They will also get guidance about the various multimedia softwares in the phone and how to use them. The study would also include teledentistry consultation as a real-time patient learning tool for patients, healthcare workers, and trainees. RESULTS: Results will be made available when the trial has been completed in 2021. The program will be evaluated by assessing its usability, acceptability, knowledge, and satisfaction of users. CONCLUSION: The protocol is designed to illustrate the underlying concept that a more reliable and robust model can be built through creating interactive communities of practice for consumers of telehealth in dental education. The Telehealth Skills Coaching and Delivery Initiative would incorporate and test a technically oriented paradigm of Internet-based medical education for vertically incorporated, community-based learning environments. CLINICAL SIGNIFICANCE: Teledentistry has the ability to expand access to oral health care, increase the provision of oral health care, and decrease costs. In view of the immense advances made in this field, teledentistry can continue to promote specialized health care in the remotest corners of the world. Many countries have already embraced virtual health care (telemedicine) in the face of an increase in cases of COVID-19; however, teledentistry has yet to play its role in this pandemic by enhancing the accuracy and efficiency of dental treatment. In the case of LMICs such as Pakistan, which lack advanced technologies such as teledentistry within their national healthcare network, the COVID-19 pandemic is a challenge to introduce the requisite legislative changes to promote the widespread use of teledentistry.

Oral Manifestations of Rett Syndrome-A Systematic Review.

Rett Syndrome is an x linked developmental disorder which becomes apparent in females after 6 to 18 months of age. It leads to severe impairments including loss of speech, loss of hand movements/manual dexterity, characteristic hand movements such as hang wringing and intellectual disability/learning problems. This systematic review was carried out to identify the dental manifestation of Rett syndrome and to shed light on treatment options available for oral health problems associated with Rett syndrome. A systematic literature search was conducted on the PubMed, Scopus, Biomed, Web of Science, Embase, Google Scholars, Cochrane and CINAHL using the following entries: Rett syndrome (n = 3790), Oral health and Rett syndrome (n = 17), dental health of Rett syndrome patients (n = 13), and the MeSH terms listed below: Rett syndrome and Oral Health (n = 17), Rett syndrome and dentistry (n = 29). The final review included 22 search articles. The most common oral findings was bruxism. Masseteric hypertrophy was also reported. Anterior open bite and non-physiological tooth wear was observed. Other oral manifestations of Rett syndrome included mouth breathing, tongue thrusting, digit/thumb sucking, high arch palate. Increased awareness and dental education amongst dentists and assistants regarding the dental manifestations of Rett syndrome and similar neurodevelopmental disorders is required to improve the level of care and empathy they can provide to these differently able patients. Research on dental aspects of Rett is scarce and this remains a neglected topic.

Relationship between Socioeconomic Inequalities and Oral Hygiene Indicators in Private and Public Schools in Karachi: An Observational Study.

BACKGROUND: The study investigated the relationship between socioeconomic status and oral hygiene indicators in two schools located in Karachi, Pakistan. Oral hygiene indicators of public and private school children were compared. Private schools cater to children of relatively wealthier families compared to public school, whose attendees are generally children from less affluent backgrounds. The aim of this study was to determine whether socio-economic differences and inequalities have an impact on key oral hygiene indicators. METHODOLOGY: Primary data for this research was collected from community school visits conducted by the community dentistry department of Jinnah Medical and Dental and Medical College from January to September 2019. A convenience sample of the two schools, comprising 300 school students was selected. Data was collected using modified World Health Organization (WHO) oral health care forms. A pre-tested/customized dental hygiene form based on WHO forms was created by the research team. This form was used to measure DMFT/dmft scores and key oral hygiene indicators in the sample. RESULTS: A total sample size of 300 school-children affiliated with public and private schools was selected. The children's age ranged from 2 to 18 years. The mean DMFT scores of private and public-school children were not significantly different (private (1.82) vs. public (1.48)). (p = 0.257). The mean of carious teeth was 1.69 in private school children compared to 1.34 in government school children, whereas the mean values of other key indicators of oral hygiene including plaque deposition (p = 0.001), dental stains (p < 0.001) and bleeding gums/gingivitis (p < 0.001), were statistically significant between public and private school children. CONCLUSION: Oral health inequalities can be reduced with increased awareness and public funding to cater for the oral health needs of children of less affluent families. A dynamic and practical community-oriented program is fundamental for enhancing pediatric oral hygiene status, particularly for children attending government schools.

Pivoting Dental Practice Management during the COVID-19 Pandemic-A Systematic Review.

Background and Objectives: The aims of this systematic review were to identify additional infection control measures implemented in dental practice globally to prevent cross-infection and evaluate the psychological impacts of the pandemic among dental professionals. Materials and Methods: A sequential systematic literature search was conducted from December 2019 to 30 April 2020 through PubMed, CINAHL, Scopus, Google Scholar, Embase, and Web of Science databases. The search yielded the following results: "COVID-19" (n = 12,137), "Novel corona virus" (n = 63), "COVID-19 and dentistry" (n = 46), "COVID-19 and oral health" (n = 41), "Novel Corona virus and Dentistry" (n = 0), "dental health and Novel Coronavirus" (n = 26), and "dental practice and Novel Coronavirus" (n = 6). Results: After a careful review and eliminating articles based on inclusion and exclusion criteria, the final review included 13 articles. Management of infection control is discussed extensively in the literature and remains the main theme of many Coronavirus Disease 2019 (COVID-19) articles on dentistry. Telephone triage using a questionnaire, hand hygiene, personal protective equipment (PPE) for clinical and nonclinical staff, a preprocedural mouth rinse, and aerosol management have been discussed and implemented in few countries. Three studies recommended that elective treatments for patients with a temperature of >100.4 F or 38 °C should be postponed or performed in an airborne infection isolation room (AIIR) or negative-pressure room. Limiting the number of patients in the waiting area, the removal of shared objects, proper ventilation, and physical distancing were highly recommended. Psychological distress among dental professionals in relation to existing medical conditions and self-efficacy has been discussed. Conclusions: Although the COVID-19 pandemic has had a substantial impact on the dental profession worldwide, our review highlights many practice management approaches to adopt the new norm. More research highlighting evidence-based safety practices and multisectoral collaboration is required to help dental professionals make informed decisions and make the profession safe, both for the patient and dental professionals.

Telerehabilitation: Review of the State-of-the-Art and Areas of Application.

BACKGROUND: Telemedicine applications have been increasing due to the development of new computer science technologies and of more advanced telemedical devices. Various types of telerehabilitation treatments and their relative intensities and duration have been reported. OBJECTIVE: The objective of this review is to provide a detailed overview of the rehabilitation techniques for remote sites (telerehabilitation) and their fields of application, with analysis of the benefits and the drawbacks related to use. We discuss future applications of telerehabilitation techniques with an emphasis on the development of high-tech devices, and on which new tools and applications can be used in the future. METHODS: We retrieved relevant information and data on telerehabilitation from books, articles and online materials using the Medical Subject Headings (MeSH) "telerehabilitation," "telemedicine," and "rehabilitation," as well as "disabling pathologies." RESULTS: Telerehabilitation can be considered as a branch of telemedicine. Although this field is considerably new, its use has rapidly grown in developed countries. In general, telerehabilitation reduces the costs of both health care providers and patients compared with traditional inpatient or person-to-person rehabilitation. Furthermore, patients who live in remote places, where traditional rehabilitation services may not be easily accessible, can benefit from this technology. However, certain disadvantages of telerehabilitation, including skepticism on the part of patients due to remote interaction with their physicians or rehabilitators, should not be underestimated. CONCLUSIONS: This review evaluated different application fields of telerehabilitation, highlighting its benefits and drawbacks. This study may be a starting point for improving approaches and devices for telerehabilitation. In this context, patients' feedback may be important to adapt rehabilitation techniques and approaches to their needs, which would subsequently help to improve the quality of rehabilitation in the future. The need for proper training and education of people involved in this new and emerging form of intervention for more effective treatment can't be overstated.

Identification of World Health Organisation ship's medicine chest contents by Anatomical Therapeutic Chemical (ATC) classification codes.

BACKGROUND: Ships should carry mandatory given amounts of medicinal products and basic first aid items, collectively known as the ship's medicine chest. Type and quantities of these products/items are suggested by the World Health Organisation (WHO) and regulated by individual flag states. In countries that lack national legislation, it is assumed that ships should follow WHO indications. An objective difficulty mainly involving vessels of international long-haul routes could be to recognise medicinal compounds obtained in other countries for replacing products used or expired. Language barrier may complicate, if not make it impossible to interpret the name of the medicinal product and/or of the active principle as indicated in a box printed in a completely different language. Handling of the ship's pharmacy may be difficult in case of purchasing of drugs abroad due to language barriers. Medicinal products are identified by the international non-proprietary name of the active principle and/or by their chemical or invented (branded) names. This may make the identification of a medicinal product difficult, primarily if it is purchased abroad and the box and instructions are written in the language of the country where it is marketed. Therefore, there is a simpler classification system of the medicinal compounds the ATC (ATC: Anatomy, Therapeutic properties, Chemical, pharmacological properties). This paper has reviewed the list of medicinal products recommended by WHO and assigned to each one the ATC code as a solution to the problem of medicinal compounds organisation. MATERIALS AND METHODS: Two researchers independently examined the list of medicinal compounds indicated in the third edition of the International Medical Guide for Ships and attributed to each compound the ATC code according to the 2013 Guidelines for ATC classification and Defined Daily Dose (DDD) assignment. RESULTS: The ATC code was attributed to the medicinal compounds indicated in the third edition of the International Medical Guide for Ships. CONCLUSIONS: The availability of an objective system to identify medicinal products is required for ships, which will contribute in making the identification of items purchased simpler, making it easier to understand which drug seafarers need to be administer, and consequently reduce possible therapeutic mistakes.

Eighty years of CIRM. A journey of commitment and dedication in providing maritime medical assistance.

BACKGROUND: A review of activities of Centro Internazionale Radio Medico (International Radio Medical Centre, CIRM) from its foundation in 1935 until its 80th anniversary in 2015 was accomplished. CIRM was founded in 1935 to provide medical assistance via radio to ships with no doctor on board and other distant patients who cannot be reached by a doctor. In 1950 CIRM was established as a non-profit-making foundation and has benefited since 1957 from an annual contribution from the Italian government. METHODS: Review of CIRM case histories and other published material from 1935 to 2015 and presenting them in a scientific yet simplified manner through the use of basic mathematical analysis. All the data was collected from CIRM's official archives in Rome. RESULTS AND CONCLUSIONS: The results achieved by the Centre over 80 years include medical assistance to 81,016 patients on board ships (as well as on small islands and aircraft), with more than 500,000 medical messages received and transmitted. CIRM from its inception was organised into a medical service, a telecommunications service and a studies section. In 2002 the Centre was recognised as the Italian Telemedical Maritime Assistance Service (TMAS). In the 2010 the Centre was reorganised as a structure articulated in 4 departments, namely maritime telemedicine, telecommunication, research and occupational medicine. This was achieved to cover the different activities related to comprehensive health protection of seafarers. The 24-h continuous medical service is provided by doctors at the CIRM headquarters. The doctor on duty gives instructions for managing the case and continues to follow the patient with subsequent appointments until recovery or landing. In case of emergencies CIRM co-ordinates the transfer of patients assisted on board ships to a hospital ashore. CIRM has developed innovative approaches for the treatment of diseases and accidents on board of seagoing vessels by introducing standard telemedicine equipment on board ships, allowing the transmission of biomedical data from ships to the Centre. These new solutions are aimed at bringing a significant improvement of medical care for seafarers.

Dental hygiene habits and oral health status of seafarers.

BACKGROUND: This study has assessed the dental hygiene habits and problems of seafarers and their attitudes/ perceptions regarding oral hygiene using a dental hygiene/habits questionnaire. MATERIALS AND METHODS: A research questionnaire on oral hygiene habits was prepared along with a summary of all the questions and sent to ships via e-mail by Centro Internazionale Radio Medico (CIRM) networks. CIRM, is the Italian Telemedical Maritime Assistance Service (TMAS), and represents the Centre with the largest number of seafarers assisted on board ships worldwide. CIRM proposed the questionnaire to all ships (n = 1,198) asking for medical advice from 1 July 2014 till 31 October 2014. Two dental professionals were involved in the development and analysis of the questionnaire. RESULTS: Seafarers are at risk of several dental health problems due to their oral hygiene and dietary habits, smoking and alcohol consumption, poor oral hygiene knowledge and motivation. Dietary habits during voyages were also questionable and seafarers consume food rich in fermentable carbohydrates, which is a major risk factor for dental caries. CONCLUSIONS: Seafarers need better oral hygiene education and care to enable them to manage their oral health in a better way. Life at the sea, under challenging circumstances is not without stress, that is why it is important that seafarers are given complete information about correct oral hygiene protocols and dental hygiene and the advantages for their health of keeping a healthy mouth.
