Background: Aesthetic correction involves a holistic approach which considers the oral cavity as a whole by the norms of the treatment. Aesthetics enhance the facial profile and also the smile line of the patient which improves the quality of life of a patient enabling them to a better socioeconomic status. Smile correction of a patient paves the path for a systematic approach to the treatment and also imparts an improved level of confidence which leads to new opportunities both in the personal and professional field. AeEsthetic correction provides challenging aspects concerning patient satisfaction and functional demands. This is the most affordable treatment for patients' who are not financially sound in developing countries like India. The other treatment modalities such as Veneers or All-ceramic crowns are aesthetically pleasing but are quite expensive for people in the lower income strata. Due to this, direct composite treatment is very economical and it also improves the patient's overall confidence and it helps them to socialise well and carry out their daily routine activities without any hindrance and difficulty. Case Report: This case report deals with the esthetic correction of midline diastema and spacing in the maxillary and mandibular anterior region. Conclusion: Aesthetic correction involves meticulous treatment planning to revive the essence of lost beauty as well as improve the functional aspect for the patient.

Orthodontics is a branch of dentistry that deals with diagnosis, prevention and correction of malpositioned teeth and jaws. Correction of malpositioned teeth is done by moving teeth and adjusting the underlying bone with the help of certain devices. Ideal age for undergoing orthodontic treatment is between 8 to 14 years. Orthodontics treatment is required for malocclusion of teeth to establish proper bite and to improve aesthetics. Malocclusion affects the individual self satisfaction, self confidence and causes emotional and mental disturbances. The aim of the study is to evaluate the awareness on orthodontics and smile correction in teenagers. A cross sectional survey was conducted among teenagers to evaluate the awareness about orthodontics and smile correction in teenagers.. The study population in the study are the teenagers with a sample size of 100. The questionnaire consisted of 20 questions and was shared to teenagers using online survey platform. 80% of the participants were aware about orthodontics and 20% were not aware. 41% of the respondents have worn braces before and 59% have not. 27% of the participants felt that their teeth alignment is perfect, 29% did not feel that way and 34% said almost perfect. 75%of the participants feel that orthodontic treatment is necessary for malocclusion of teeth, 7%did not feel as necessary and 18% maybe felt as necessary. From the results obtained, we can include that the moderate level of awareness is seen in teenagers about orthodontic treatment. More awareness is required as treatments are more effective when done at an early age. [ABSTRACT FROM AUTHOR]

In order to effectively address challenges related to anterior teeth restoration and achieve natural-looking results, considerations such as shape, size, gingival contour, and color are crucial. Due to an increasing desire for visually appealing alternatives that are free of metal, materials such as dental zirconia have become popular because of their superior aesthetics and mechanical characteristics. This case report presents clinical insights into anterior teeth rehabilitation with the use of layered zirconia fixed dental prostheses. It delves into the experiences associated with zirconia dental restorations on both endodontically treated and vital abutments, aiming to discern how various factors influence treatment outcomes. Beginning with the design of the restoration, its intricacies significantly impact its fit, strength, and overall durability. Moreover, the composition of zirconia used plays a pivotal role, as different formulations offer varying degrees of mechanical properties, influencing factors such as resilience and wear resistance. The shade selection is also scrutinized, as it directly affects the restoration's aesthetic integration with surrounding natural teeth, contributing to a more harmonious smile. Furthermore, the layering technique employed, particularly when additional porcelain or ceramic layers are applied, is essential for both cosmetic enhancement and structural integrity. Lastly, considerations of occlusion are paramount, ensuring proper alignment and contact between teeth to prevent premature wear and discomfort. By exploring these facets in zirconia restorations across different abutment types, this inquiry seeks to illuminate best practices for achieving favorable treatment outcomes in dental restoration procedures. The choice of zirconia composition, framework design, and shade must be carefully tailored to suit the characteristics of each individual abutment. This emphasizes the significance of adopting a tailored approach to tackle the distinct challenges posed by every clinical scenario. The manuscript provides detailed observations from a clinical case involving the restoration of anterior teeth utilizing monolithic zirconia-fixed dental prostheses. Through a combination of root canal treatment and composite buildup, successful restoration was achieved, with meticulous attention paid to aesthetic considerations. The utilization of computer-aided designing/computer-aided manufacturing (CAD/CAM) technology in crafting zirconia restorations ensured precise fit and superior biocompatibility, contributing to the overall success of the treatment. The study underscores the importance of personalized treatment strategies in achieving optimal outcomes in anterior teeth restoration, emphasizing the need for careful consideration of various factors such as design, composition, and shade selection. Overall, the findings shed light on the potential of zirconia-based restorations in addressing the unique challenges associated with anterior teeth rehabilitation, offering valuable insights for dental practitioners striving to deliver aesthetically pleasing and functionally sound outcomes for their patients., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Dhamande et al.)

An attractive smile enhances an individual's self-confidence. The overall harmony of a smile can be attributed to the interplay of the teeth's shape, color, and position along with the gingival tissue. Gingival pigmentation is observed across all human races, exhibiting variations from one race to another. Typically, gingival hyperpigmentation results from the abnormal buildup of melanin in the gingival tissue, imparting a dark appearance on the gums. Various procedures, collectively known as gingival depigmentation, are employed to address gingival hyperpigmentation. While the initial outcomes of depigmentation procedures are often promising, one common issue associated with them is the potential for re-pigmentation. This article aims to evaluate the clinical effectiveness and patient-reported outcomes of intraepidermal (oral mesotherapy) vitamin C injection for nonsurgical management of physiologic gingival melanin hyperpigmentation., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, S et al.)

Onboard image processing systems for a hyperspectral sensor have been developed in order to maximize image data transmission efficiency for large volume and high speed data downlink capacity. Since more than 100 channels are required for hyperspectral sensors on Earth observation satellites, fast and small-footprint lossless image compression capability is essential for reducing the size and weight of a sensor system. A fast lossless image compression algorithm has been developed, and is implemented in the onboard correction circuitry of sensitivity and linearity of Complementary Metal Oxide Semiconductor (CMOS) sensors in order to maximize the compression ratio. The employed image compression method is based on Fast, Efficient, Lossless Image compression System (FELICS), which is a hierarchical predictive coding method with resolution scaling. To improve FELICS’s performance of image decorrelation and entropy coding, we apply a two-dimensional interpolation prediction and adaptive Golomb-Rice coding. It supports progressive decompression using resolution scaling while still maintaining superior performance measured as speed and complexity. Coding efficiency and compression speed enlarge the effective capacity of signal transmission channels, which lead to reducing onboard hardware by multiplexing sensor signals into a reduced number of compression circuits. The circuitry is embedded into the data formatter of the sensor system without adding size, weight, power consumption, and fabrication cost.

The Environmental Mapping and Analysis Program (EnMAP) is an upcoming German hyperspectral satellite mission aiming to observe and characterize the Earth's environment on a global scale. In course of a the development of the EnMAP ground segment processing chain, measures were taken to deal with probable spectral and spatial distortion effects of the sensor, that can only be addressed by post-processing once the satellite platform is launched into orbit. One of these effects is a pixel- and band-wise spectral distortion, the so called sensor smile effect. This paper describes the methods and performance of the smile correction process as implemented for the EnMAP ground segment processing chain, explaining design choices and difficulties currently encountered with the proposed approach and evaluating the results of the smile correction on basis of simulated EnMAP hyperspectral data.

Esthetic dentists, these days must be well equipped to satisfy the needs of cutting edge society. All ceramic restorations have gained wide recognition as a number one mode of altering in esthetic dentistry. As affected person's esthetic expectancies maintain to growth, dental groups are challenged to perceive a systematic approach for accomplishing oral and facial esthetics with ceramics. Advances in ceramic materials and veneering strategies permit practitioners to repair features and esthetics using conservative and biologically sound methods as well as promoting a long time oral fitness. The esthetic and restorative applications of dental ceramics have expanded and will continue to evolve with time. A 25-year-old male came to Saveetha Dental College and Hospital with a chief complaint of broken, fixed partial denture and compromised esthetic because of discoloration of the tooth. On clinical examination, the patient had generalized enamel fluorosis affecting all the permanent teeth. The case document describes the esthetic management of mild to extreme fluorosis patient with ceramic veneers. Fluorosis is endemic in a few regions of northern India as a result of consuming well water with excessive fluoride content. Bleaching or microabrasion of critically fluorosed teeth are frequently ineffective or gives temporary results while composite resin veneers not only dis-color and wear with time, however quite frequently become chipped or debonded as glazed ceramics retain its color while being wear resistant, noticeably biocompatible and a lifelike esthetics. The esthetic and restorative applications of dental ceramics have expanded and will continue to evolve with time16. However, the clinicians must be sensible in responding to the ever-inflating esthetic needs of the patients, such as every process in dentistry, the achievement of ceramic veneers, and crowns rely on understanding the principals involved in their fabrication and application. The success of treatment may be assured if the dentist follows a described protocol with each patient to ensure that each one factor consisting of smile design, margin placement material, and shade selection are considered. Communication among patient, dentist, and technician is of extreme significance. It is extremely vital to procure an informed consent from the patients before considering such cases. It's also essential to discuss the practical and biological implications of his or her preference. [ABSTRACT FROM AUTHOR]

Two new angled half-beam transformation systems (BTSs) for the reduction of the beam-divergence problem in laser-diode arrays with large smiles are investigated. Both simulations and experiments show that the angle of divergence of laser-diode arrays with the parabola-shaped smile and the S-shaped smile can be reduced by more than 37% and 23% respectively, when two angled half-BTSs are used in front of the laser-diode array. Furthermore, a fiber-coupling module, with a 400 μ m core-fiber and two angled half-BTSs, is fabricated. The optical/optical coupling efficiency increases to more than 85%, which is an improvement by more than 4% over laser diodes that use a full-BTS. [ABSTRACT FROM AUTHOR]
