INTRODUCTION. The problem of parents and children staying together in intensive care units (ICU) is solved from a categorical ban in the past, to exceptional loyalty at the present time, when it is allowed to stay with the patient of his beloved pets. OBJECTIVES. To study the social and psycho-emotional aspects of the joint stay of parents with a child in the intensive care unit as an indicator of satisfaction with the medical care. MATERIALS AND METHODS. Hospitals with a commitment to a family centered care (FCC) were included in the study. Data collection was carried out on the basis of questionnaires (n = 471), when filling out which the respondent had to choose one of the submitted answers with a score from 1 to 5 (the highest), or in some cases submit their own version. The data were analyses by descriptive. RESULTS. Respondents rated 4 (4–5) the conditions of stay in the ICU, concerning: its location in a medical institution; the purpose of the premises of the department and the quality of their sanitary and hygienic cleaning; diagnostics, treatment, care; communication and psycho-emotional support by medical staff. The nature of the assistance provided by family members to the patient: sanitary and hygienic care (87.9 %), feeding (86.4 %), monitoring of medical equipment (50.9 %), assistance to medical staff in transporting the patient (53.5 %). The level of training of parents in caring for a child in the ICU upon admission is 3 (3–4), and upon transfer from the department 4 (4–4). CONCLUSIONS. The joint stay of parents with children in the ICU does not bring a negative psycho-emotional burden for them in communicating with medical staff, allows parents to obtain and improve their knowledge and skills in child care, to provide assistance in this. The problem of FCC requires further study.

A Study on Thriving Mediterranean Cuisine Attracting Tourism in Dubai
Authors: Gupta Ragini , Rawal Yashwant Singh
Published: August 2022

Mediterranean cuisine is well-known throughout the world and is widely regarded as the healthiest cuisine in every way. Although it is regarded as a cuisine that encompasses all the Mediterranean Sea nations, it differs from one to the next, with many variants based on the culture and cuisine of each country. Mediterranean cuisine, also known as "sun cuisine," has been proven to be the healthiest and most balanced, thanks to the richness of its flavours and the use of very healthy ingredients. Because of its widespread popularity, UNESCO designated it as Intangible Cultural Heritage in 2013, acknowledging that it offers several health and lifestyle advantages. This cuisine has succeeded to incorporate many cultures into a single culinary style while retaining its distinct characteristics. They all have the same essence that distinguishes them from the rest of the world's kitchens, even though they use extremely diverse materials and methods. When we speak of Mediterranean food, we may refer to Italian, Spanish, Greek, Moroccan, French Provençal, or even North African cuisine, all of which are part of the same family yet distinct from one another. The chapter discuses about the Mediterranean Cuisine and how it is Attracting Tourism in Dubai

Authors: Miranti Aufa , Mansur Teuku Muttaqin , Sulaiman Sulaiman , Jalil Faridah
Published: August 2022

Hareuta peunulang is a grant of immovable property from parents to their daughters before marriage in Pidie Regency, Aceh Province. Disputes are resolved through customary court, but the settlement that should have been settled at the mukim level was brought to the Mahkamah Shar'iyyah. Therefore, this study aimed to identify the causes of the hareuta peunulang practice disputes and find an effective and efficient model for resolving them through customary courts. Empirical juridical methods were used with data collected data through observation and interviews and analyzed using a qualitative descriptive approach. The results showed that disputes are caused by the lack of deliberation in the hareuta peunulang process. The social plurality of laws makes the dispute resolution model through customary courts ineffective and inefficient. Therefore, the role of the village head (keuchick) and head of mukim (imuem mukim) is needed to educate the community regarding customary justice procedures that should to conducted at the village (gampong) and mukim levels.
Traditional Law vs. Islamic Law; An Analysis of Muslim Community Awareness in Inheritance Issues
Authors: Hamdani Fahmi Fatwa Rosyadi Satria , Pebrianti Suci , Dzulhijjah Liza , Maricar Hudzaifah Muhammad
Published: August 2022

The system of inheritance distribution in Islamic law, normatively, between men and women is 2:1. Meanwhile, the traditional inheritance system of the Cipicung Girang community, Cidadap District, Bandung City, where the majority of the population is Muslim, has divided men and women equally, namely 1:1. Another uniqueness of the system is that the house they live in belongs to the child who is the last to take care of his parents. The problem is, the customary inheritance system is used by the majority Muslim population. This study aims to analyze the factors that influence public awareness in the distribution of inheritance. This study uses a mix-method with interactive analysis techniques and assisted by Smart PLS software to test the relationship between variables. This study found that inheritance follows the local traditional system because girls take care of their parents, while men are busy working. Another finding is that literacy factors have a greater influence on people's awareness and loyalty compared to religiosity and perceptions of inheritance.

The Atlantic Forest is one of the richest and most threatened biomes in the world, a fact that configures it as a global hotspot. We provide here a list of bird species recorded in the municipality of Barra Mansa (RJ), during ten years of ad libitum observations in a fragment of Semideciduous Seasonal Forest, one of the most devastated phytophysiognomies of this biome. We recorded 192 species, of which 107 present some degree of forest dependency, 22 that present migratory activity, 24 that are endemic in the biome or in Brazil and 5 that are relevant to conservation as they are almost threatened or vulnerable at some level (global, national or state). Regarding the trophic guild, there was a predominance of insectivorous (n=67) and omnivorous (n=58) species, which denotes some environmental quality, but pressured by an imminent anthropization. Given the obtained results, the importance of the analyzed fragment for the maintenance of the local biodiversity becomes evident.

O conhecimento sobre a fauna de uma região e seus padrões de distribuição espacial é de grande relevância para ações de conservação e gestão ambiental. Nesse sentido, nos últimos anos tem ganhado força o uso de bacias hidrográficas como unidades regionais para tais ações. No presente estudo, é realizada uma análise integralizada, utilizando dados de observações esporádicas e secundários, originados de publicações científicas, banco de dados e estudos ambientais, da fauna de vertebrados terrestres, registrados na bacia do Rio Irani, localizada no oeste do estado de Santa Catarina, sul do Brasil, quanto ao seu estado de conservação e fatores que influenciam sua distribuição. Foram analisadas 481 espécies de vertebrados terrestres, sendo 332 espécies de avifauna, 66 espécies de mastofauna e 83 espécies de herpetofauna. Esse valor é maior do que a riqueza previamente conhecida para a bacia. Dessas espécies, para a avifauna, 8% estão ameaçadas de extinção; para a herpetofauna, 10%; para a mastofauna, 15%. Todas as regiões da bacia tiveram associação com alguma espécie ameaçada. Os dados mostram que o processo de gestão dessa bacia deve ser feito de forma unificada, não podendo ficar restrito a determinadas localidades.

Published: August 2022

Há poucos estudos polínicos de méis de abelha mandaçaia (Melipona quadrifasciata quadrifasciata Lepeletier) no Brasil e, principalmente, no Rio Grande do Sul (RS). Os dados melissopalinológicos são necessários para se conhecer interações das abelhas com a biota vegetal e trazer fidedignidade aos produtos de origem apícola e meliponícola. Visando avaliar as fontes florais de abelha mandaçaia ao longo de um ano e meio no RS, coletaram-se 46 amostras de méis em duas áreas da região leste do estado (26 amostras do município de Canoas e 20 amostras de Cachoeirinha). A análise polínica foi realizada com a metodologia melissopalinológica (material a fresco) sem uso de acetólise. Foram identificados 34 tipos polínicos, sobretudo de plantas arbóreas nativas. As amostras foram reunidas em cinco grupos pelo CONISS, denominadas Manda-1, Manda-2, Manda-3, Manda-4 e Manda-5. Os principais tipos polínicos com altas porcentagens nas amostras foram: tipo Myrcia, Eucalyptus sp., Mimosa bimucronata, Schinus terebenthifolia e Solanum sisymbriifolium. A porcentagem polínica das plantas variou entre os meses e estações do ano. A ocorrência de plantas nativas, especialmente arbóreas, próximo aos meliponários é importante, já que o pólen delas predominou nos espectros polínicos dos méis de mandaçaia na região leste do Rio Grande do Sul.

The success of implant-supported prostheses is related to the passive union between the prostheses’ connections and the implants, so it is necessary to obtain an accurate working cast. Objective: To evaluate the accuracy of the transfer impressions of implants performed with individual acrylic resin trays and conventional trays using polyvinyl siloxane. Material and methods: To carry out the transfer impressions, a master cast with four external hexagon implants parallel to each other was used. Five impressions were made with individual acrylic resin trays and five other impressions with modified conventional trays, opened in the region of the implants. The linear measurements between the implants were made with a digital caliper with an accuracy of 0.01 mm and the results were statistically evaluated �(alpha = 5%)�. Results: For the points AB and BC, the measurements obtained with the individual trays were statistically similar to the master cast. For the points CD and DA no statistical differences among the three groups were observed. Conclusion: Given the obtained results and the methodology used, it can be concluded that the impressions performed with individual trays presented higher accuracy compared to the ones obtained with conventional trays.

The sanitation of the canal system through irrigation/aspiration, at the changing of the endodontic instruments aims to the excised material, removal of microorganisms and the cleaning of the walls of the canals. One of the substances used in endodontic treatment of root canals, sodium hypochlorite, used at different concentrations of active chlorine and pH, has gained popularity due to its physical chemical properties. Objective: To analyze the active chlorine content of sodium hypochlorite solution at 6.0%. Material and methods: 80 samples were obtained from two litres of sodium hypochlorite at 6%, obtained at every hour: one liter was stored at room temperature and one liter at refrigerated environment, between the morning and afternoon shifts, except on Saturday and Sunday. The free residual chlorine was determined, using as variables: the temperature, length of time in storage and the handling of the substance in the Endodontic clinic for seven days. The data obtained were submitted to analysis of variance according to the linear regression model to test the effect of time of storage condition and interaction between the main effects on the chlorine content of the stocked solution (p < 0.01). Results: The results showed that the sodium hypochlorite solution is quite unstable, with considerable loss of active chlorine (58.33%), depending on the storage conditions and storage time and temperature. The temperature interferes in the free residual chlorine concentration contained in sodium hypochlorite solution, that is, the higher the temperature, the lower the lifetime of free residual chlorine in sodium hypochlorite solutions. Conclusion: Storage in refrigerated environment proved to be the best option to avoid the marked loss of active chlorine in sodium hypochlorite of concentration at 6%.

The clinical longevity of the procedures is directly associated to the adequate activation (photopolymerization) of adhesive restorative materials. Objective: To evaluate and compare by allocation the conservation status and power density of the light-curing units available at the School of Dentistry of the Federal University of Goias (FO/FUG) for clinical care. Material and methods: The following information and specific techniques of all light sources existing at FO/UFG, available for clinical care in 2011, were collected: dental/ambulatory clinic where they are located, type of source [device of halogen light and light-emitting diode (LED)], brand, parallelism test (halogen light sources), state of conservation of the light transmitter tip, density of the potency/intensity/irradiance in mW/cm2 and acquisition date. The data obtained were submitted to one-way ANOVA (Analysis of Variance) and Turkey test for multiple comparisons (P < 0.05). Results: In the second half of 2011, FO/UFG had 20 light sources (04 halogens and 16 LEDs), of which 90% were found in inadequate condition and 55% of those with power density less than 300 mW/cm2. There was no statistically significant difference in the power density between halogen and LED sources tested (P = 0.526). Likewise, no statistical difference was observed between the power density of the light sources (LED) placed at the Clinic II and III (P = 0.479). Also there was no statistically significant difference between the light sources (LED Halogen X) at the Clinic I (P = 0.943). Conclusion:The light sources regardless of the clinic in which they were located presented mostly with inadequate clinical effectiveness in terms of their conservation status and power density.

Cell adhesion in bone grafts associated to nanotechnology: a systematic review
Authors: Haroldo Gurgel Mota-Filho  , Amanda Alencar Cabral  , Diego Moura Soares  , Fernanda Ginani  , Carlos Augusto Galvão Barboza
Published: August 2022

Tissue engineering aims at the development of biological substitutes that can restore, maintain, or improve the functionality of damaged tissue or organs. To this end, molecular and cellular interactions may influence the tissue reactions to biomaterials. In order to be effective and integrated to the receiving area, the bone graft is required to allow a strong cell adhesion, interacting with several molecules to induce migration, differentiation, and thus the mineralization of the new bone on the graft. These cell adhesion molecules (CAM) will mediate the contact between two cells or between cells and the extracellular matrix, an essential process to the success of the implant. Objective: This paper is a systematic review of the literature on the mechanisms of cell adhesion to bone grafts associated to nanotechnology, describing the importance and the role of those molecules in the adhesion and thus in tissue regeneration. Literature review: After the use of search strategies, 18 articles that describe processes of cell adhesion to bone grafts were selected. Results: The main reported mechanisms involve cell adhesion molecules (CAMs) and extracellular matrix components. Conclusion: Several molecules are involved in the process of cell adhesion to bone grafts, highlighting the role of integrins, the focal adhesion mechanism, the influence of the collagen matrix, and the activity of alkaline phosphatase in bone matrix formation. Accurate identification of these mechanisms of cell adhesion is essential for further advancement in tissue engineering, such as the production of biological bone substitutes that achieve a better clinical outcome.

Public and health professionals have become more aware of the importance of oral mucosal lesions. Objective: To determine the frequency of the oral lesions and determinate the epidemiological profile of patients attending the prevention of oral cancer campaigns in the state of Paraná, Brazil, between 1988 and 2013. Material and methods: A prospective study was conducted evaluating 25 years of oral cancer prevention campaigns in the state of Paraná, Brazil, between 1988 and 2013. All patients were evaluated in a systematic way and were older than 30 years, answering one questionnaire with data relating to harmful health habits, family history of cancer, family income, frequency of visits to dentists and knowledge on the subject. Results: A total of 22,300 patients were evaluated during the 25 years of projects and 3,731 had oral lesions, while 18,569 patients had no oral alterations during the evaluation. Among those patients, 13779 (61.78%) were female and 8521 (38.78%) were male, 843 (22.59%) were smokers, 578 (15.49%) used alcohol and in 1386 (37.14%) had the habit of using yerba mate. The prevalence of lesions occurred as follows: 533 (14.28%) cases of lesions with aspect of leukoplakia, 1095 (29.34%) inflammatory lesions, 1934 (51.83%) of traumatic origin and 169 (4 5%) classified as other. Conclusion: The campaigns have brought benefits to the health of the elderly population but it is still not enough to make up for low levels of oral lesions appearance. Education of the population should in this way be approached more seriously and effectively.

The second step was performed after seven days and the third after thirty days to reassess the Simplified Oral Hygiene Index to check whether there would a change in their values. Participants were divided into two groups according to Simplified Oral Hygiene Index: those who had only bacterial plaque and those who had plaque and calculus. Results: At the first day, patients with plaque and calculus had initial OHI-S mean of 2.3 (regular), 2.1 (regular) after seven days, and 2.4 (regular) after one month. Patients with only plaque at the first day had an average OHI-S of 0.71 (regular), 0.74 (regular) after seven days, and 0.78 (regular) after one month. Conclusion: Within this context, it is possible to understand that it is necessary to implement frequent supervised toothbrushing, oral instruction and motivation activities to promote wellness and health for these patients.

Root canal system filling aims to the hermetic sealing of the space formerly occupied by the dental pulp. Objective: The aim of this study was to analyze the bacterial infiltration of Enterococcus faecalis in root canals filled through two techniques: single cone technique (group A) and thermoplasticized gutta-percha technique (group B). Material and methods: A total of 40 single-rooted human premolars were divided into two experimental groups (n = 15) and two control groups: positive (n = 5) and negative (n = 5). The root canals were prepared with ProTaper Universal system up to size F3 file and filled with the corresponding gutta-percha point. Teeth were mounted on a dual-chamber model, where the infiltration of E. faecalis was evaluated for a 30-day period by BHI turbidity indicating bacterial growth. Results: After the trial period all specimens in experimental and positive control groups showed turbidity of the culture medium. The average number of days until culture medium turbidity was 11.42 days for group A, 16.69 days for group B, and 5.5 days for positive control. By applying Anova test, there was no statistically significant difference between groups (p > 0.05). This allowed the observation that no difference between the obturation techniques in the infiltration of E. faecalis could be observed by the methodology used. Conclusion: It can be concluded that regardless of the obturation techniques, bacterial infiltration occurred.

The mandibular molars are a group of teeth that have a complex internal morphology, and its fundamental knowledge is necessary. The second molar has two roots, one mesial and distal, but three canals are more commonly find: two in the mesial root and one in the distal root. Objective: To study through four criteria: radiographic, clinical, microscopic, and anatomy, the internal morphology of the mandibular second molars. Material and methods: This was a cross-sectional, in vitro, descriptive, observational study, in which 50 second molars were selected, having as exclusion criteria teeth destroyed by caries. Inclusion criteria comprised teeth with higid and semi-higid crowns Results: ��� of mandibular second molars had three canals. The round-shaped cross section was the most common throughout the cervical-apical extension of both mesial (59%) and distal (47%) canals. However, other possible configurations and number of canals can be found in second molars, as the presence of four (12%) or five canals (3%). 36.7% of the mesial canals and 29.4% of distal canals were flattened in the mesial-distal direction and elongated in buccolingual direction; the variation of the "C-shaped" canal was found in 4% of cases. Conclusion: The most frequent configuration and number of canals of mandibular second molars were, respectively, the round-shaped cross section configuration in the entire length of the canal, and three canals. However the professional should be aware that this morphology may vary as shown in each research phase. Therefore, to achieve clinical success, the professional should have the knowledge of the internal morphology of these teeth and their possible variations.

Authors: Cinthia Sawamura Kubo¹  , Fabrício Reskalla Amaral  , Edson Alves de Campos
Published: August 2022

The alveolar bone resorption that occurs after tooth loss leads to maladaptation of prostheses over the mucosa, causing discomfort to the patient. However, these maladaptations can be solved by prosthesis relining. Objective: The aim of this study was to discuss based on the literature, the relining of complete and partial removable dentures. Literature review: Dentistry makes use of relining materials that can be either rigid or resilient, having a temporary or permanent characteristic. However, to obtain a satisfactory result, the knowledge of their indications, contraindications, advantages, disadvantages is required, in addition to the characteristics and types of materials. Patients should be aware of the importance of constant monitoring, or even the need to reline their dentures, as it is not possible to determine the biological tolerance of each individual. Conclusion: The installation and proservation phases become essential to minimize bone resorption, and also to achieve rehabilitative treatment success.

Dentinal hypersensitivity consists in an increasing problem at dental offices and new approaches may be developed. Objectives: The authors studied different desensitizing treatments and their efficacy in reducing dentinal permeability and dentinal tubules opening. Material and methods: One hundred bovine incisors roots had their buccal surface flattened and treated by 3 applications of each desensitizing agent, following the respective groups (n = 10). After treated, 7 specimens of each group were prepared for a 0.5% basic fuchsin permeability test and the other 3 specimens were prepared to SEM qualitative analysis. The permeability test specimens were sectioned with a diamond saw in order to evaluate the stained and unstained areas. Kruskall Wallis statistical analysis was performed (p < 0.05). Results: Colgate Pró-Alívio paste and toothpaste, diode and Nd:YAG Lasers, GHF, Sensi Active, Oxagel and 2% Desensibilize promoted a significant permeability reduction when compared with the respective control groups (p < 0.05). Comparing the mean permeability differences between the different groups after the treatments, Oxagel and Nd:YAG were better than 0.2% Desensibilize group. Conclusion:None of the treatments may be considered 100% effective in treating dentinal hypersensitivity since a partial reduction of the permeability was observed.

Nanoleakage evaluation by silver uptake in permanent teeth provides good spatial resolution of submicron defects at the hybrid layer, which have not been tested in primary teeth. Objective:This study evaluated the nanoleakage at the dentin-adhesive interface in primary teeth by two methods, for three adhesive systems, immediately (IM) and six months (6M) after adhesive procedures. Material and methods: Crowns of primary molars were occlusal flat grounded and divided into three groups according to the adhesive system tested (n = 6-7). Scotchbond Multi-purpose/SMP, Single Bond/SB and Clearfil SE Bond/CSB adhesive systems were applied with a composite resin (Filtek Z-250). Crowns were sectioned so that 0.8 mm² sticks were obtained and subdivided depending on the time of evaluation: IM or 6M. They were immersed into silver nitrate solution and evaluated by SEM-EDS. Data (%) were analyzed by ANOVA (p < 0.05) and the scores by Kruskal-Wallis and U Mann-Whitney tests (p < 0.05). Results: There was no difference between groups regarding to the evaluation time (aging) percentage. In terms of scores, there was a significant difference for the adhesive variable: SMP and SB showed similar results with less leakage, while CSB demonstrated higher leakage. Conclusion: Nanoleakage was not influenced by aging, but noticeable difference was observed between total-etch and self-etching adhesives. Total-etch showed better performance.
Influence of the chlorhexidine application on adhesive interface stability: literature review
Authors: Carla Miranda  , Gabriela Vieira Silva  , Mariáh Damiani Vieira  , Simone Xavier Silva Costa
Published: August 2022

There is a consensus that dentine/resin bonding deteriorates over time, and such degradation is one of the main reasons for limiting adhesive restoration longevity. Enzymes known as matrix metalloproteinases (MMPs) are responsible by enzymatic degradation of collagen fibrils without protection, which are present in the resin-dentine interface. Therefore, these enzymes are involved in the process of adhesive interface degradation. Currently, studies point out chlorhexidine digluconate has antiproteolytic function by inhibiting the action of MMPS. Thus, it is thought this substance application prior to the use of bonding agents could slow the process of degradation of the tooth-restoration interface, resulting in longevity. Objective: To review the literature on the influence of chlorhexidine application on the stability of the adhesive interface. Literature review: Chlorhexidine digluconate proprieties and its application in Dentistry were discussed. Next, hybrid layer formation and degradation was discussed and the mechanism of action of chlorhexidine on preserving this layer was detailed. Finally, scientific studies from the last six years were analyzed on the performance of adhesive systems after chlorhexidine application. Results: Considering the results of reviewed studies, it can be concluded that chlorhexidine application did not interfere on the immediate bond strength to dentin and hybrid layer degradation over time occurred later and/or with lower intensity. Conclusion: Chlorhexidine application interferes positively when incorporated into the adhesion protocols, by promoting hybrid layer stability over time.

Published: August 2022

A problem of endodontic origin is solved mainly by cleaning and disinfecting the root canal system. However, the use of medicines for systemic use is a great auxiliary in combating pain, inflammation and/or infection, making easier to treat the clinical status, that patient experiences less pain. Objective: To conduct a literature review evidencing the clinical indications of systemic medication application in endodontics, to aid the professional in achieving more effective and safer therapeutics. Literature review: There is a wide variety of drugs available on market. Consequently, the dentist is uncertain when prescribing systemic medication because a pharmacological arsenal is available. Also, the dentist frequently does not know the mechanism of action of these drugs and their interactions. Additionally to analgesics, anti-inflammatories and antibiotics, used to combat pain, inflammation and infection, respectively, dentists can still make use of anxiolytics, in cases of patients very fearful to endodontic treatment. Conclusion: It is of fundamental importance that the dentist knows about the medication type to be used in each case and whether systemic therapy is really necessary, through a comprehensive case evaluation.
