Oral health is an integral part of general health. Different population groups have been assessed for oral health status in India, but still, many have been neglected; one such group is the prisoners. The prison population is a unique and challenging one with many health problems, including poor oral health, which may be due to lack of knowledge about good oral health practices. This study aims to assess effectiveness of oral health education on oral health knowledge, attitude and practices and oral hygiene status among the male prison inmates of central jail in Kolkata, India.

An interventional study was done among 240 male convicts. The data was elicited using a structured proforma; oral health status was assessed by recording OHI-S index, and the severity of gingivitis was assessed by recording the gingival index. Oral health education was delivered by using audio-visual aid. Oral health knowledge, attitude, practices and oral hygiene and gingival status were reassessed among the inmates before and after dental education at the end of three and six months.

A significant change in oral health knowledge, attitude and practices was seen, which in turn resulted in an appreciable decrease in the mean gingival index score (1.73 ± 0.382 to 1.20 ± 0.321) and OHI-S (3.31 ± 0.815 to 2.57 ± 0.551) in all the inmates after oral health education program over the period of time.

The oral health education with reinforcement proved to be an effective tool to instil good oral hygiene practices in the inmates.

Prisoners’ oral health is an often overseen, yet important aspect of the general health of prisoners. To develop effective measures to improve the situation, it is important to get an overview of existing research. The purpose of this study is to examine and analyse existing research on oral health of prisoners and provide a thorough understanding of prisoners’ oral health and related factors.

Due to relatively few scientific papers on prisoners’ oral health, an integrative review was chosen. Integrative reviews allow for the inclusion of diverse methodologies. A literature search was conducted, followed by an assessment of the quality of the studies by using the Mixed Methods Appraisal Tool. Thematic analysis was used to analyse the studies.

The few studies addressing European prisoners’ oral health in the last 21 years differ in design and methodology. The results from this review indicate that prisoners’ oral health is a complex phenomenon and should be understood from both individual and organisational perspectives. More research is needed to bridge the gap in the literature on prisoners’ oral health.

To the best of the authors’ knowledge, this is the first literature review on European prisoners’ oral health.

Menstruation is a part of the female reproductive cycle that begins with adolescence. Menstruation is a natural change; it relates to several malpractices and misconceptions that may contribute to adverse health outcomes.

The authors have searched relevant papers using Google Scholar and PubMed to write this mini review.

During menstruation, poor hygiene maintenance can cause serious illness, which includes the urinary tract and reproductive tract infection. Menstruation management is a hygienic system, and it is essential for females because poor hygiene maintenance during menstruation can cause some infections and numerous sexually transmitted diseases. There are a few nanotechnology-based products that have come into the market to offer some relief to females during their periods.

This mini review will help researchers to design innovative female hygiene products that can relieve the discomfort caused to women during their reproductive age.

Environmentally friendly products are finding a place in everyday lives more frequently, like bamboo toothbrushes. However, the authors find no statement from consumer protection centers about their impact on the human well-being or dental health in daily use. Therefore, this study aims to investigate the tribological parameters between tooth, toothpaste and toothbrush laboratory tests with a focus on abrasive wear.

The real-world system was systematically transferred to a laboratory scale, which was implemented to a Schwing-Reib-Verschleiß tribometer tribometer (Optimol Instruments). For an abstraction of the real-world system, as many components of the original tribosystem as possible were retained. In addition, the abstraction was selected so that the method could be transferred to other tribometers. For the evaluation of the test subjects, an optical measurement method was developed to investigate the forms of wear.

Based on eight test series, it is possible to differentiate between the tribological partners by the wear results. With the help of the measurement method, it will be possible to recommend the use of sustainable oral hygiene products for everyone in everyday life in future. According to the findings, the use of low-cost toothbrushes and highly abrasive toothpaste should be avoided. The effects of an aggressive brushing technique cannot be compensated by gentle toothbrushes and toothpastes.

To the best of the authors’ knowledge, this is the first approach to investigate the wear behavior of tooth–toothpaste–toothbrush while substitute the tooth with dental gypsum. The approach is relevant for developing screening tests with high respect to transferability to the real-world application.

The purpose of the study is to classify the radiographic images into three categories such as fillings, cavity and implant to identify dental diseases because dental disease is a very common dental health problem for all people. The detection of dental issues and the selection of the most suitable method of treatment are both determined by the results of a radiological examination. Dental x-rays provide important information about the insides of teeth and their surrounding cells, which helps dentists detect dental issues that are not immediately visible. The analysis of dental x-rays, which is typically done by dentists, is a time-consuming process that can become an error-prone technique due to the wide variations in the structure of teeth and the dentist's lack of expertise. The workload of a dental professional and the chance of misinterpretation can be decreased by the availability of such a system, which can interpret the result of an x-ray automatically.

This study uses deep learning (DL) models to identify dental diseases in order to tackle this issue. Four different DL models, such as ResNet-101, Xception, DenseNet-201 and EfficientNet-B0, were evaluated in order to determine which one would be the most useful for the detection of dental diseases (such as fillings, cavity and implant).

Loss and accuracy curves have been used to analyze the model. However, the EfficientNet-B0 model performed better compared to Xception, DenseNet-201 and ResNet-101. The accuracy, recall, F1-score and AUC values for this model were 98.91, 98.91, 98.74 and 99.98%, respectively. The accuracy rates for the Xception, ResNet-101 and DenseNet-201 are 96.74, 93.48 and 95.65%, respectively.

The present study can benefit dentists from using the DL model to more accurately diagnose dental problems.

This study is conducted to evaluate dental diseases using Convolutional neural network (CNN) techniques to assist dentists in selecting the most effective technique for a particular clinical condition.

This paper aims to examine how the interrelation between architecture and the physical environment came to prominence and influenced the pioneering modernist architects to acquire the features of modern architecture that the British modernists later adopted. How the post-war urban poor of Britain, suffering from ill-health and dire need of sun, air and a good environment, played an essential role in alleviating the environmental concerns of the modern movement architects.

The methodology of this research involves a comprehensive architectural analysis of the Finsbury Health Centre alongside an in-depth historical investigation of modernist design principles. This review article examines books, articles and some archival materials, such as recordings, pictures, etc. on the early phase of British modernism and its environmental dimension by looking at the works of historians, architects and critics.

Design based on modernist principles. While it can be seen as the political agenda of the Labor Party, this building was not only functionally efficient but also represented the biometric concerns of modern architecture with the most natural means.

While this study provides valuable insights, it may be limited by historical documents and data availability.

The originality and value of this paper lie in its examination of the Finsbury Health Centre as a case study, shedding light on the environmental rhetoric of modernism in historic architecture. By providing a holistic assessment of the building’s environmental aspects, this research contributes to both architectural history and contemporary sustainable design practices.

Stereolithography (SLA) additive manufacturing (AM) technique has enabled the production of inconspicuous and aesthetically pleasing orthodontics that are also hygienic. However, the staircase effect poses a challenge to the application of invisible orthodontics in the dental industry. The purpose of this study is to implement chemical postprocessing technique by using isopropyl alcohol as a solvent to overcome this challenge.

Fifteen experiments were conducted using a D-optimal design to investigate the effect of different concentrations and postprocessing times on the surface roughness, material removal rate (MRR), hardness and cost of SLA dental parts required for creating a clear customized aligner, and a container was constructed for chemical treatment of these parts made from photocurable resin.

The study revealed that the chemical postprocessing technique can significantly improve the surface roughness of dental SLA parts, but improper selection of concentration and time can lead to poor surface roughness. The optimal surface roughness was achieved with a concentration of 90 and a time of 37.5. Moreover, the dental part with the lowest concentration and time (60% and 15 min, respectively) had the lowest MRR and the highest hardness. The part with the highest concentration and time required the greatest budget allocation. Finally, the results of the multiobjective optimization analysis aligned with the experimental data.

This paper sheds light on a previously underestimated aspect, which is the pivotal role of chemical postprocessing in mitigating the adverse impact of stair case effect. This nuanced perspective contributes to the broader discourse on AM methodologies, establishing a novel pathway for advancing the capabilities of SLA in dental application.

Iron deficiency anemia (IDA) is the most common nutritional anemia in the world and a pervasive health problem, especially in developing countries. Children under two years of age are more prone to be affected by IDA. The best strategy to prevent and treat IDA is to use iron supplements. This study aims to examine the factors associated with noncompliance (such as non-utilization or inconsistent usage) of iron drop supplementation among infants between 6 and 24 months old.

Online databases (PubMed, Scopus and SID) were searched to retrieve relevant articles published from inception up to July 2023. Among the 2,177 articles detected, after removing duplicate and irrelevant titles, 21 cross-sectional studies that met the authors’ inclusion criteria were included. Screening for articles and data extraction were conducted separately by two researchers.

The findings suggest that some factors related to mothers, such as education, knowledge, attitude and performance; some factors associated with child such as child’s gastrointestinal and dental complications; taste and smell of iron drops; and birth order and gender are the main determinants of adherence to iron supplementation.

It can be proposed that the most significant factors affecting the feeding of iron drops to children under the age of two include: the level of mother’s awareness, socio-economic status of the household and the occurrence of digestive complications following the supplementation. Given these observations, adopting proper policies toward improving the nutritional awareness of mothers and producing iron supplements with minimal side effects seems crucial.

The public healthcare system faces challenges and limitations regarding the supply and delivery of healthcare services. The private healthcare system is expensive and only affordable for some. Due to the increasing population, developing countries face a greater degree of demand–supply mismatch. The existing healthcare services in developing countries need to be more sustainable due to high out-of-pocket expenditures and low-income levels. The research design used in this chapter is a case study approach based on qualitative data. The study focuses on two objectives: (1) to have a detailed understanding of the nature of healthcare cooperatives in Spain and their contribution to meeting healthcare requirements; and (2) to make suggestions and recommendations for an improved and sustainable healthcare cooperative for developing countries. Inspired by the healthcare cooperative model of Spain and keeping in mind the ground reality of the lack of healthcare facilities and services accessible and affordable in developing countries, the authors have developed a conceptual framework with the foundation of an insurance cooperative. The Spain Model is sustainable for developing countries as it serves the interest of all income brackets, not leaving the low-income population behind. Concepts like cooperative worker insurance embedded in the model can ensure that the beneficiaries receive timely and good quality health services at an affordable price. It empowers individuals by allowing them to make small amounts of investments as premiums to secure a hopeful future for a healthy life.

The COVID-19 pandemic has caused significant mortality and morbidity worldwide. However, the role of dietary patterns as a potential risk factor for COVID-19 has not been well established, especially in studies with large samples. Therefore, this study aims to identify and evaluate the association between major dietary patterns and COVID-19 among adults from Iran.

In this cross-sectional study, the authors included 9,189 participants aged 20–70 who participated in the Yazd Health Study (YaHS) and Taghzieh Mardom-e-Yazd study (TAMIZ). They used factor analysis to extract dietary patterns based on a food frequency questionnaire (FFQ). Then, they assessed the relationship between these dietary patterns and the odds of COVID-19.

This study identified two major dietary patterns: “high protein and high fiber” and “transitional”. Participants in the highest tertile of the “high protein and high fiber” dietary pattern, which included vegetables, fruits, dairy and various kinds of meats such as red meat, fish and poultry, had a lower odds of COVID-19 compared with those in the lowest tertile. However, the “transitional” dietary pattern did not affect the risk of COVID-19.

In conclusion, a “high protein, high fiber” diet may lower the odds of COVID-19. This study suggests that dietary patterns may influence the severity and spread of future similar pandemics.
