Comparison between normative and self-perceived needs
The aesthetic aspect plays an important role in the social interaction of individuals. In some situations, the presence of aligned teeth seems to have a strong influence on the perception of beauty, identification with professional success and intelligence, and is even associated with more socially advantaged individuals. Orthodontic treatments are carried out in the hope of improving the appearance and masticatory function of individuals and are generally indicated and carried out using clinical or epidemiological criteria (normative needs), i.e. based on professional decisions. However, these criteria can overestimate occlusion problems. The aim of this study was to compare the technically defined orthodontic needs (normative criteria) and the self-perceived needs (subjective criteria) of 428 adolescents aged between 15 and 19, of both genders, from the Londrina-PR public school system. Clinical examinations were conducted to verify the presence of malocclusions (normative need for orthodontic treatment), using the diagnostic criteria established by the Dental Aesthetic Index (DAI).

It seeks to understand how traits are passed from parents to offspring and how these traits are expressed in individuals. The fundamental unit of genetics is the gene, a segment of DNA that contains the instructions for making proteins, which perform most life functions and form the structure of cells and tissues. DNA, or deoxyribonucleic acid, is composed of nucleotides arranged in a double helix structure.
Effects of Mouthwashes on Elastomers In Orthodontics
Elastomeric chains are polyurethane copolymers frequently used in orthodontic operations due to their versatility. They are effective, colorful, and comfortable for patients. Since the 1960s, elastomeric chains have been employed in orthodontic therapy for widespread space closure, midline correction, extraction space closure, and relocating impacted teeth. Andreasen and Bishara were pioneers in describing how these elastic chains could be used to close minor gaps between teeth.Due to their viscoelastic qualities, elastomeric chains are subject to force decay over time. This force decay is influenced by several factors, including the temperature within the oral cavity, fluctuations in pH levels, the presence of free radicals, and the use of mouthwashes. These factors collectively contribute to the degradation of the force exerted by the chains.
Remineralization of Dental Caries - Biomimetic Approach
Until recently, the conventional treatment concept for all carious teeth involved caries excavation and replacement with a restorative material. However, with decades of research, evolved the "minimally invasive" approach which incorporates detecting and treating these areas sooner, emphasizing on prevention, rather than the traditional surgical model. Despite dental caries being a preventable infectious disease, oral health promotion and prevention can fail due to many factors. The advanced cavitation of the carious lesion necessitates restoring the tooth with materials such as metals, composite resins and ceramics to replace the lost enamel or, even, dentin. However, modern dental materials to repair cavitated carious lesions are not compatible with biological tissues at the lesion/restorative material interface mainly because of their physical and chemical differences (elemental compositions and phases) compared to the natural tooth structure. Remineralization is the natural repair process for non-cavitated lesions. The aim of remineralization of a caries lesion is to make the previously demineralized tissue mineralize, and put mineral back into a lesion.

Contacts and Contours
Optimizing tooth form has always been the "holy grail" of restorative dentistry. Recreating the missing tooth anatomy is important to not only replace lost structure but also to re-establish ideal form and function. Nature has done her best in the way of making an anatomic arrangement to avoid trouble. It remains for the dentist to assist nature by copying as best he may the arrangement thus provided, when he attempts to make fillings on the proximal surfaces. Contacts and contours location, susceptibility to dental decay, treatment, and role in preventive dentistry have been taken into consideration in theory and practice for centuries. Earlier concept in treating proximal caries was to remove the caries and fill the cavity with the appropriate materials without taking into consideration tooth form and function. In order to produce a contoured filling, Atkinson et al introduced concept of matricing. Matricing is the process of replacing dental structure that was lost during preparation by building a temporary wall opposing the axial walls of the preparations.

These tumors can arise in any of the major or minor salivary glands located in and around the oral cavity, including the parotid, submandibular, and sublingual glands, as well as numerous minor glands distributed throughout the lining of the mouth and throat.These tumors are relatively rare, accounting for only a small percentage of all head and neck cancers. However, they exhibit a wide range of clinical behaviors and can vary significantly in their presentation, growth patterns, and aggressiveness. Malignant salivary gland tumors can be classified into various subtypes based on their histological characteristics, which often dictate their clinical management and prognosis.Despite advancements in diagnostic techniques and treatment modalities, managing malignant salivary gland tumors can be challenging due to their diverse nature and potential for recurrence and metastasis.
Influence of the restorative material on a monolithic implant crown
The aim of this study was to evaluate the influence of the prosthetic crown material on the biomechanical performance of the stress distribution received by the abutment (universal trunnion), implant (cone morse) and bone tissue (cortical and medullary) in the first molar region, using the finite element method (FEM). Three different monolithic ceramic system materials for CAD/CAM (Computer Aided Design/Computer Aided Manufacturing) were analysed, represented by models: DL - lithium disilicate, RN - nano ceramic resin and CP - polymer infiltrated ceramic. The virtual models of the prosthetic crowns received occlusal compressive loading at 5 vertical points of 200N. The results obtained were the highest stress values for NR in the cortical and medullary bone, implant and abutment, followed by the CP results, and the lowest DL values. In the crown, the highest values were for DL, with average values for CP and the lowest values for the RN model. It can be concluded that the material of the crown influences the distribution of stresses and according to the results, the DL model showed better biomechanical behaviour.
Maxillary Sinus Lift
Maxillary sinus lift, also known as sinus augmentation or sinus elevation, is a surgical procedure performed to increase the amount of bone in the upper jaw, specifically in the area of the maxillary sinuses, which are located behind the cheeks and above the upper teeth. This procedure is commonly done in preparation for dental implant placement when there is insufficient bone height in the posterior maxilla due to sinus expansion or bone resorption.

Many dental anomalies have been considered to be the primary feature of some syndromes. They may be the cause of various dental problems. Careful observation and appropriate investigations are required to diagnose the condition and institute appropriate treatment. A multidisciplinary approach may contribute to the success of the treatment. The treatment not only improves speech and masticatory function, but also has psychological implications that may greatly help in regaining self-confidence.
Dental Manpower of India
India is the most populous nation in the world with a 1.4 billion population due to its enormous population, to meet its demands for oral health, India needs more dental manpower.A dental auxiliary is a person who is given responsibility by the dentist so that he or she can help the dentist render dental care, but who is not qualified with a dental degree. in developing countries like India, the oral health promotion guidelines demonstrate ways to extend resources to meet a boarder base of needs.Workforce planning is an essential element in planning future health service provisions. Factors of supply and demand for dental services are changing, making it all the more important for workforce planning to prevent future projected shortages or surpluses. In a society that steadily increases its consumption of health services, a correspondingly increasing the workforce is needed.
Non Pharmacological Behavior Management Techniques
Dental health professionals need to acquire an understanding of the dynamic nature of child dental anxiety to allow them to appreciate the hidden feelings and underlying complexity associated with the presentation of the anxious child patient. Doing so will provide the basis for empathetic care of the child dental patient, reduce the potential for regression as well as the fantasies stirred up by and connected with the actual dental treatment experience. By careful handling of the child and parent(s), the dental team can assist the fearful child cope and accept dental treatment. It is during these times that the dentist's clinical and patient management skills are most thoroughly tested. Success requires a personal knowledge of the patient and an understanding of human behavior, development. Proper assessment of children's behavior helps the dentist to plan appointments and render effective and efficient dental treatment. Appropriate use of management techniques can improve the child's behavior in subsequent dental visits. Finally, the most effective communication always reflects the personality of the dental professionals themselves.
Management of open apex
Dentistry has significantly evolved with the latest technology over the years. These advancements have improved the precision, efficiency, and comfort of various dental treatments and has lead to a paradigm shift in treatment approaches. An open apex is a dental condition characterized by the incomplete formation of the root of a tooth, particularly in young individuals whose teeth are still developing. The lack of a fully developed root canal system complicates dental health and treatment. An open apex in a tooth is typically the result of disruptions in the normal process of tooth development and root formation. The absence of a fully developed root canal system complicates procedures, making it harder to achieve effective outcomes. Additionally, the risk of pulp pathology and compromised structural integrity further underscores the complexities of managing such cases. Managing open apex teeth requires precision and strategic approaches to promote proper root development and preserve tooth integrity. The general consensus for clinical treatment of immature teeth with vital pulps is to preserve remaining normal vital tissue to allow continued physiological development.
