A estrutura fitoplanctônica é influenciada por fatores ambientais, ciclos sazonais e grau de trofia do sistema. O objetivo do presente estudo foi identificar como a diversidade de espécies fitoplanctônicas responde à fatores ambientais como a sazonalidade e estado trófico do reservatório Billings, localizado na Região Metropolitana de São Paulo (RMSP). Variáveis físico-químicas e biológicas foram analisadas no Corpo Central (CC) e Braço Rio Grande (RG), ao longo de um ciclo sazonal (fevereiro a novembro de 2020; n = 6). A densidade fitoplanctônica foi obtida pela contagem de organismos por mL e os índices de diversidade, riqueza e equitabilidade foram calculados. O cálculo do índice de estado trófico evidenciou gradiente no grau de trofia, sendo RG caracterizado como mesotrófico e CC como eutrófico. A composição fitoplanctônica consistiu em 138 táxons, sendo 34 registrados exclusivamente no CC e 33 registrados somente no RG. A riqueza taxonômica, diversidade e equitabilidade apresentaram pequena variação no CC e RG. A abundância fitoplanctônica variou espacial e temporalmente. As maiores densidades foram registradas no CC, sendo que o grupo de cianobactérias foi o mais representativo (80% de contribuição). No RG, além das cianobactérias, foi registrada contribuição das algas verdes e diatomáceas. O fitoplâncton se mostrou sensível como ferramenta para monitorar a dinâmica dos processos de eutrofização e formação de florações de algas e de cianobactérias.

O aleitamento materno é ideal para o suprimento das necessidades alimentares e nutricionais durante os primeiros seis meses de vida trazendo diversos benefícios não só para o recém-nascido, mas também para a mãe e à família. A recomendação para boas práticas do aleitamento materno exclusivo é até os seis meses de idade. O objetivo desta pesquisa foi identificar na literatura os fatores associados à manutenção e/ou interrupção do aleitamento materno exclusivo nos primeiros seis meses de vida no Brasil. Trata-se de uma revisão integrativa da literatura, os dados foram coletados nas bases de dados: Literatura Latino-americana e do Caribe em Ciências da Saúde (LILACS), SCIELO e BDENF, além das bases PUBMED e SCOPUS, totalizando 10 artigos após aplicação dos filtros selecionados. Com base nos resultados, a adesão ao aleitamento ou desmame precoce está associada a assistência prestada pelos profissionais durante o acompanhamento pré-natal. São vários os fatores contribuintes para a interrupção, como a baixa escolaridade materna, maior tempo de internação na Unidade de Tratamento Intensivo Neonatal (UTIN), falta de informação e estímulo por parte dos profissionais e a percepção materna de não ter uma quantidade suficiente de leite.  A experiência prévia com amamentação mostrou-se ser um fator importante para a manutenção do aleitamento materno exclusivo. Além disso, traz o papel da família e/ou rede de apoio da mãe para manutenção, o que foi contrário a alguns achados da literatura, enfatizando que esta realidade não é homogênea.

Authors: Costa Thayssa Duarte , Oliveira Heloísa Arruda Soares de
Published: February 2024

The impact of climate change on piracema and the sustainability of aquatic resources are essential topics in riverine conservation. Piracema refers to the reproductive period of fish, during which they masse migrate to specific locations for spawning. Thus, climatic variations altering environmental conditions directly affect this vital cycle. This study addresses the implications of these changes, emphasizing the vulnerability of the mentioned phenomenon and delineating its repercussions on aquatic biodiversity. Through scientific articles and academic works, it was analyzed that temperature elevation, irregular rainfall patterns, and extreme climatic events can compromise the migration and successful reproduction of fish. Therefore, conservation strategies, including community engagement, infrastructure adaptation, and continuous scientific research, are essential to mitigate these impacts. The sustainability of aquatic resources depends on a delicate balance between preserving piracema and active participation in adaptive management, fostering a healthy coexistence between riverine ecosystems and human communities.

Heavy metal pollution of soil has increased globally in recent years. In many dry and semi-arid locations throughout the world, wastewater is seen as a novel and unusual supply of water for agricultural development. As a result, soil and plant monitoring for a variety of factors, including heavy metals and hazardous contaminants, is necessary. The farmers in Shakargarh use wastewater and tube wells for crop production, however workers and customers are concerned about the possible public health hazards linked with the use of wastewater. This investigation aimed to determine the health threats of using wastewater for crop production by estimating heavy metal concentrations in vegetable crops. Vegetables samples (radish and turnip), soil and irrigation water were collected from critical points and examined for the detection of heavy metals (copper, chromium, cadmium, cobalt, and arsenic) by atomic absorption spectrophotometer. Vegetable parts were collected at the growing stage and at the time of harvesting from farmers’ fields. Three soil sampling campaigns were carried out from the radish and turnip plots. Irrigation water samples were collected from different water bodies including wastewater and the tube well water. The following metals were detected: copper, chromium, cadmium, cobalt, and arsenic in the tested samples. It was observed that the high concentration of these metals in the roots of radish at fruiting stage: Cu (39 mg kg-1), Cr (201 mg kg-1), Cd (1.3 mg kg-1), Co (54 mg kg-1), and As (17.3 mg kg-1). It was found that mean concentration of these metals in the roots of turnip at fruiting stage: Cu (34 mg kg-1), Cr (178 mg kg-1), Cd (2.1 mg kg-1), Co (49 mg kg-1), and As (14.1 mg kg-1). The general pattern for the distribution of heavy metals in different parts of the plant was roots stem leaves fruits. The incidence of heavy metals in soil samples was highest for chromium followed by copper, arsenic, cobalt and cadmium. The incidence of heavy metals in irrigation water samples was highest for chromium followed by copper, cadmium, arsenic, and cobalt. These concentrations were significantly greater than the permissible level recommended by FAO / WHO. It can be inferred that the health threats associated with the consumption of vegetables are currently very significant. Therefore, it is recommended that irrigation water, soil, and vegetables be monitored on a regular basis to safeguard the health of workers and consumers.

The design of thermal protection modules (such as film cooling) for combustion chambers requires a high-fidelity swirling flow field. Although numerical methods provide insights into three-dimensional mechanisms of swirling flow, their predictions of key features such as recirculation zones and swirling jets are often unsatisfactory due to inherent anisotropy and the isotropic nature of the Boussinesq hypothesis. Experimental methods, such as hot wire, laser Doppler velocimetry, and planar particle image velocimetry (PIV), offer more accurate reference data but are limited by sparse or planar observations. In this study, considering the outperformed capability of solving inverse problems, physics-informed neural network (PINN) was adopted to reconstruct the mean swirling flow field based on limited experimental observations from two-dimensional and two-component (2D2C) results. It was found that adding partial information characterizing the swirling flow, such as the swirling jet, could significantly improve the reconstruction of flow field. In addition, film cooling effectiveness was the key variable to evaluate the film cooling performance, which was relatively measurable in the scalar field. To further improve the accuracy of the reconstruction, the multi-source strategy was adopted into the neural network, where the film cooling effectiveness (FCE) of the effusion plate was imported as the scalar source. It was found that the prediction of the flow field near the target plate was improved, where the highest error reduction could reach 76.5%. This study aims to diagnose the three-dimensional swirling flow field with deep learning by leveraging limited experimental data so that obtains a more accurate reference in the design of thermal protection modules.

The Water-Enhanced Turbofan (WET) is a future concept for aero engine applications being developed by MTU Aero Engines AG. Steam is injected into the combustion chamber to reduce temperature peaks and emission of pollutants. Depending on the steam content, the combustion process is modified. To analyze the effect of steam on the reaction kinetics and the temperature, detailed chemistry has to be employed. By comparing laminar flame speed and mole fraction distribution across the flame front, an appropriate chemical mechanism for the considered operating conditions including high steam loads was selected. Tabulated chemistry based on flamelets was employed, which enables the use of complex mechanisms in CFD analysis at reasonable computational costs. A comparison of premixed freely propagating flames and non-premixed counterflow diffusion flames to represent the manifolds was investigated. Various definitions of the progress variable are studied for ultra WET combustion considered under aero engine conditions. The manifolds from both model flames are compared from dry to ultra WET conditions with kerosene in an adapted Sandia Flame D large eddy simulation. While the premixed flamelets are generated efficiently, the results obtained with non-premixed flamelets are more reliable for the range of operating conditions investigated.

A typical non-surgical healing of a large periapical lesion: An accident or decree? -A case report
Authors: Khera Archie , Haque Shehla W
Published: February 2024

Abstract:
Periapical diseases are mostly induced as a result of direct or indirect involvement of oral bacteria. The causative factors include oral contaminants through the root canal or degenerating pulpal tissues. Hence, only surgical removal of the periapical lesions without proper root canal disinfection and obturation will not result in the healing of periapical tissues. The aim of this case report is to present a biologic rationale for the non -surgical endodontic management of large periapical pathosis of pulpal origin. Emphasis is laid on thorough debridement, placement of intracanal medicament and three dimensional obturation of root canal system by a simple lateral condensation technique in a non-compliant patient.

“Effect of low friction chromium surface coating of drills on heat generation during simulated implant osteotomy preparation: an in vitro study”
Authors: Nagarajan Aswin , Rengaswamy Venkat , Balasubramaniam Muthukumar , Kalambettu Aravind
Published: February 2024

Brief Background
To evaluate the effect of low friction chromium surface coating of drills on heat generation during implant osteotomy preparation in standardized simulated bone blocks.

Materials and Methods
32 Artificial polyurethane bone blocks were used as the study models. 32 twisted stainless-steel design drills of three different sizes 2.0mm, 2.4mm and 2.8mm x 18mm were used. Drills were divided into two groups as control (Group 1) and low friction chromium coated (Group 2) drills. Surface coatings of drills were made for Group 2 drills with Low friction chromium. Standardized drilling protocol was used to avoid influence of other drilling factors on heat generation. Osteotomies were performed and temperatures were recorded during drilling procedure using thermocouples at different depths of 4mm, 8mm and 12mm.

Method
In this study, it was observed that the temperature changes in the thermocouples reading were significant (p<0.001) when compared with control and test group drills, proving that LFC coated drills reduced the heat generated during implant osteotomy preparation due to reduction in frictional contact between the drills and bone. Also, the temperature changes recorded at different depths of drill site showed an increase in temperature with increase in depth of drill site but the values were not statistically significant (p>0.5) to prove the result.

Summary and Conclusions
Drill depth did not have a significant (p>0.5) effect on heat generation during implant osteotomy preparation. Low friction chromium surface coating can reduce heat generated during implant osteotomy preparation by reducing the frictional contact between the bone and the drill surface.

Impact of COVID 19 and Importance of Its Vaccination in Dental Professionals: A Brief Review
Authors: Raje Yashoradha , Jamwal Vishwajeet Singh
Published: February 2024

The COVID 19 pandemic hit dental care providers hard in 2020 as the fears of COVID 19 infection kept millions of people away from seeking routine oral health treatments and care. Now with times as the dental offices have ratcheted up their safety measures, the patients have steadily been returning for dental checkups. As the dentists were included in the first phase of recipients of vaccine, hope of returning to their normal practices is increased. It is extremely important for dentists to get themselves vaccinated especially older dentists, dentists in large care settings and specialists. This will enable them to return to their usual routines and practices and will increase the doctors and patient’s confidence too. The aim of the study is to provide an insight on the impact of COVID 19 pandemic on the dentists who are on the high list of systemically important professions and the importance to receive vaccine sooner than later as they are irreplaceable as other health professionals when it comes to provide seamless health care to society.

Summary and Conclusions
As clinicians themselves and also as frontliners, dentists need to play their part to maintain universal infection control measures in their daily practice as the nature of their work,working in close proximity to the oral cavity renders them at high risk of exposure to COVID 19 infection. Not only vaccines keep them safe but they will ensure that the patients who come to their practices remain safe as well.

Management of decayed primary anterior teeth using Silver diamine fluoride and preformed zirconia crowns: a minimal intervention and aesthetic approach
Authors: Jena Debarchhana
Published: February 2024

Early childhood caries is the most common chronic dental disease in children worldwide. Maxillary anterior teeth being the first ones to get affected. It is disheartening to encounter young children with grossly carious maxillary anterior teeth that disturb their natural smile, and their entire facial appearance restricts masticatory function and causes delayed speech. Treatment objective for carious maxillary anterior teeth must consider structural, functional and aesthetic components comprehensively. Management of a young child with early childhood caries requires complete cooperation, which is a challenging task, and treatment under various forms of sedation has become popular.

Nevertheless, sedation increases the risk of the patient and clinician. In such scenarios minimally invasive treatment approach can be an alternative. Silver diamine fluoride (SDF) is the best possible antibacterial & cost-effective remineralising agent available today. SDF application is non-technique sensitive hence acceptable by young children. Preformed zirconia crowns serve as the best aesthetic option with excellent strength and durability for primary maxillary anterior teeth. A combination of ideal remineralisation with an aesthetic restoration can provide long term benefit to the child and parents.

Published: February 2024

Class II skeletal dysplasias have always been a challenge in orthodontics and often require surgical management in adjunct to Orthodontics in non growing patients when presented with a severe discrepancy. Difficulty increases more when the patient also has a vertical dysplasia in congruence with a sagittal discrepancy. The advent of mini implants in orthodontics has expanded the envelope of camouflage treatment. This case report presents a female patient with a skeletal Class II base attributable to retrognathic mandible and an orthognathic maxilla showing Vertical Maxillary excess, treated non-extraction with absolute intrusion of maxillary arch using Infra zygomatic crestal (IZC) bone screws bilaterally in the posterior and two inter radicular implants in the anterior region.

Mucocele Removal – A Challenge to Dentist
Authors: Patel Chandra Bhushan Singh , Bagchi Gautam , Sharma Abhinav , Choudhary Kanaram
Published: February 2024

Mucocele is a salivary gland disorder that can appear in the oral cavity, Lacrimal sac, Paranasal sinuses, Appendix, or gall bladder but lower lip is the most common site. These lesions occur due to mucous retention resulting from the alteration of minor salivary glands. Most common cause to develop mucocele is trauma or habit of lip biting. Diagnosis is mainly clinical due to its characteristic pathognomonic presentation. Treatment encompasses complete surgical excision with intact lining. Proper diagnosis and application of surgical skill leaves almost nil chances to reoccur. We report a case of mucocele lower lip in adult treated by conventional surgical excision of the lesion.

Lesch-Nyhan syndrome (LNS), is a rare inborn error of metabolism. It is characterized by neurological and behavioral abnormalities and the overproduction of uric acid in the body. It occurs almost exclusively in males. Signs and symptoms may include inflammatory arthritis (gout), kidney stones, bladder stones, and moderate cognitive disability. It is characterized by self-injurious behaviour, which results in partial or total destruction of oral and perioral tissues and/or fingers and hands. Prevention of self-mutilation raises significant difficulties. Treatment modalities include drug therapy, oral appliances, and extraction of teeth This case report is of a 13-year-old boy with aggressive behaviour and severe lower lip and tongue injuries.

Published: February 2024

In this case report, a non- compliant method of molar distalization has been described. The molar thruster appliance has been modified to provide a more bodily movement of the molar distally. This method has been a more effective and efficient method of space gaining. A report on a 25-year-old male patient who was treated with unilateral molar distalization has been described. However, more high quality studies are required to study its long term stability.

Adult skeletal Class III malocclusion with periodontal complications
treated by orthodontic camoufl age: A case report
Authors: Sabapathy Kanan , Naveed Niha
Published: February 2024

ABSTRACT
Treatment of skeletal class III malocclusions is a challenging one for orthodontists. In non-growing adults, this becomes even more difficult to treat due to the limited treatment options available. The ideal treatment for adults with Class III malocclusion is often orthognathic surgery. However, the only way to camouflage the skeletal Class III condition in patients who decline surgery is through dentoalveolar compensations. This case report presents the case of a 64-year-old man with a class III skeletal base treated with non-surgical orthodontic camouflage treatment. The patient presented with periodontal problems, and orthodontic treatment placed the teeth in a more stable occlusal position to prevent further breakdown. In this particular case, the functional demands outweigh the esthetic demands, and hence orthodontic treatment was aimed at fulfilling these demands.

Keywords: Adult orthodontics, Mini-implant, Occlusal rehabilitation, Orthodontic camouflage, Skeletal class III malocclusion.
Interdisciplinary orthodontic camouflage treatment with extraction of fractured maxillary central incisor and tooth substitution to treat skeletal bimaxillary protrusion- A case report
Authors: Sabapathy Kannan , Naveed Niha
Published: February 2024

Malformed or fractured central incisors with poor prognosis could be the choice of teeth for extraction when space is required for orthodontic treatment. This case report refers to a 14-year-old girl who had a fractured upper left central incisor associated with bimaxillary protrusion. She expressed her concern to correct her dental appearance and enhance her smile aesthetics. The patient had class I malocclusion with bimaxillary proclination and severe crowding in the lower arch. Due to the increased space requirement, extraction of teeth was required as part of orthodontic treatment. Patient had a class 2 skeletal profile with prominent upper front teeth and therefore increased space requirement in the upper arch in order to retract the prominent teeth to achieve favourable aesthetics. The choice of teeth for extraction were 14,34,44 and 21. In the second quadrant the central incisor was extracted due to its poor prognosis, and the lateral incisor, canine and first premolar were substituted for the central incisor, lateral incisor and canine respectively. In the lower dental arch the first premolars were extracted. The end of treatment objectives- class 1 molars, canines, incisors were achieved with greatly improved smile aesthetics.

Management of Non-Vital Teeth with open Apices using MTA as an Apical Plug: A Case Report
Authors: Anchala Karthik , Singaraju Anuja , Rahul Shaik , Elicherla Niharika Reddy
Published: February 2024

Dental professionals face a challenge in managing nonvital teeth with an open apex. In this situation, keeping the obturation material inside the boundaries of the root canal without extending into the periapical area is challenging. In order to allow root filling to be compacted, the apexification procedure attempts to close the open root apex with a hard tissue barrier. Therefore, the root canal obturation described in the current case report involved the use of a thermoplasticized gutta-percha after an MTA-made apical plug in an open apex tooth.

Key Words
Open apex, mineral trioxide aggregate, apexification, apical barrier.

Uncovering Hidden Roots: The Fascinating Case Series of Radix Entomolaris and Radix Paramolaris in Mandibular Molars
Authors: Kapadia Krupa , Norton Abhishek
Published: February 2024

Achieving success in endodontic treatment necessitates proper identification of the canals, thorough chemomechanical preparation, and three-dimensional obturation with an airtight seal. However, treatment failure can occur due to unpredictable tooth morphology. Although mandibular molars typically possess two roots containing three canals, the number of roots and canals may vary in certain teeth. These variations include the presence of an additional root, known as radix entomolaris (RE) if located distolingually, or radix paramolaris (RP) if located mesiobuccally. In this case series, we present six cases of mandibular first, second, and third molars with rare microstructures; one with RE and the other with RP respectively, both of which required endodontic treatment to achieve successful outcomes.

Key Words: Additional third root; Anatomical variations; Endodontic treatment; Mandibular molar; Radix entomolaris; Radix paramolaris
