1. The document discusses digital smile design (DSD), which uses presentation software like PowerPoint to analyze facial and dental photos and simulate smile designs.
2. The DSD workflow involves taking photos, applying reference lines, analyzing proportions, and simulating tooth shapes. This information is transferred to diagnostic wax-ups and provisional restorations.
3. DSD provides benefits for esthetic diagnosis, communication between clinicians and technicians, feedback throughout treatment, and patient management by helping visualize treatment plans.
Digital Smile Design (DSD) is a digital tool that can strengthen esthetic diagnosis, improve communication between team members, and help organize treatment planning. It does this through a number of steps:
1) Careful analysis of facial and dental features through overlaying reference lines on digital photos to identify limitations and risk factors.
2) Allowing effective communication between team members who can discuss solutions by adding information directly to shared digital slides.
3) Allowing the dental technician to develop a three-dimensional wax-up more efficiently based on guidelines provided through the two-dimensional DSD.
The document describes the Digital Smile Design (DSD) protocol, a tool for treatment planning and communication in esthetic dentistry. The DSD involves taking diagnostic photos and videos of the patient's smile and face. Reference lines are drawn on the digital photos to analyze esthetic factors like the smile line, midlines, tooth proportions and positions. This information guides development of a treatment plan and waxup. The DSD facilitates communication between the dental team and provides feedback at each treatment stage. It helps explain treatment to patients and improves predictability, efficiency and outcomes in esthetic dental treatments.
This document describes the Digital Smile Design (DSD) protocol, a tool for improving esthetic dental treatment planning and communication. The DSD involves digitally superimposing reference lines and shapes on patient photos to better visualize esthetic issues. This aids diagnosis, communication between dental professionals, feedback on treatment progress, patient education and management, and education of other professionals. The protocol outlines transferring reference lines from photos to dental casts or models to guide treatment from design to completion. Consistent use of DSD makes the treatment planning process more effective and predictable, reducing costs and treatment time.
This document summarizes 6 smile design cases completed by Christian Coachman and other dentists. Each case summary includes 1-2 sentences on the pre-operative situation, treatment plan and materials used. Treatments included veneers, crowns, onlays and monolithic restorations using materials like Emax. The full case descriptions provide step-by-step explanations of the smile design process from facial analysis to mock-ups and final restorations.
This document discusses the importance of considering esthetics as the starting point in treatment planning. It advocates for creating a mock-up or digital design of the desired final smile early in the process to aid communication between the dental team and patient. This upfront visualization of the treatment goal helps sequence orthodontic, restorative, and other procedures and ensures they work in harmony to achieve the planned esthetic outcome. New digital technologies further enhance this process by allowing designs to be shared, modified, and used to guide steps of the various specialties involved.

IRJET- Real Time Facial Expression Detection using SVD and Eigen VectorIRJET Journal
This document discusses a method for real-time facial expression detection using singular value decomposition (SVD) and eigenvectors. It first detects facial regions using skin color modeling, then extracts the lip region. It compares the lip region to templates of different expressions to recognize the emotion. This method is presented as simpler and faster than analyzing the full facial region, needing only a small database of templates. Seven classic emotions are discussed in terms of the facial cues that help recognize each one, from an evolutionary perspective. The methodology involves steps for face detection, capturing images, applying SVD to create eigenfaces for emotion recognition.
This document discusses smile design in direct tooth-colored restorations. It outlines key components that must be considered when designing an aesthetic smile, including dental midline alignment, tooth dimensions and proportions, gingival health, and soft tissue harmony. The smile design process involves detailed facial and dental analysis to evaluate these elements and plan restorative treatments if needed. Techniques for smile enhancement mentioned include whitening, bonding, veneers, crowns, dental implants, and gum contouring. An ideal smile design harmoniously integrates all smile components to complement the patient's overall facial appearance.

PGx Analysis in VarSeq: A User’s PerspectiveGolden Helix
Since our release of the PGx capabilities in VarSeq, we’ve had a few months to gather some insights from various use cases. Some users approach PGx workflows by means of array genotyping or what seems to be a growing trend of adding the star allele calling to the existing NGS pipeline for whole genome data. Luckily, both approaches are supported with the VarSeq software platform. The genotyping method being used will also dictate what the scope of the tertiary analysis will be. For example, are your PGx reports a standalone pipeline or would your lab’s goal be to handle a dual-purpose workflow and report on PGx + Diagnostic findings.
The purpose of this webcast is to:
Discuss and demonstrate the approaches with array and NGS genotyping methods for star allele calling to prep for downstream analysis.
Following genotyping, explore alternative tertiary workflow concepts in VarSeq to handle PGx reporting.
Moreover, we will include insights users will need to consider when validating their PGx workflow for all possible star alleles and options you have for automating your PGx analysis for large number of samples. Please join us for a session dedicated to the application of star allele genotyping and subsequent PGx workflows in our VarSeq software.

Breast cancer :Receptor (ER/PR/HER2 NEU) Discordance.pptxDr. Sumit KUMAR
Receptor Discordance in Breast Carcinoma During the Course of Life
Definition:
Receptor discordance refers to changes in the status of hormone receptors (estrogen receptor ERα, progesterone receptor PgR, and HER2) in breast cancer tumors over time or between primary and metastatic sites.
Causes:
Tumor Evolution:
Genetic and epigenetic changes during tumor progression can lead to alterations in receptor status.
Treatment Effects:
Therapies, especially endocrine and targeted therapies, can selectively pressure tumor cells, causing shifts in receptor expression.
Heterogeneity:
Inherent heterogeneity within the tumor can result in subpopulations of cells with different receptor statuses.
Impact on Treatment:
Therapeutic Resistance:
Loss of ERα or PgR can lead to resistance to endocrine therapies.
HER2 discordance affects the efficacy of HER2-targeted treatments.
Treatment Adjustment:
Regular reassessment of receptor status may be necessary to adjust treatment strategies appropriately.
Clinical Implications:
Prognosis:
Receptor discordance is often associated with a poorer prognosis.
Biopsies:
Obtaining biopsies from metastatic sites is crucial for accurate receptor status assessment and effective treatment planning.
Monitoring:
Continuous monitoring of receptor status throughout the disease course can guide personalized therapy adjustments.
Understanding and managing receptor discordance is essential for optimizing treatment outcomes and improving the prognosis for breast cancer patients.
A congenital heart defect is a problem with the structure of the heart that a child is born with.
Some congenital heart defects in children are simple and don't need treatment. Others are more complex. The child may need several surgeries done over a period of several years.
Congestive Heart failure is caused by low cardiac output and high sympathetic discharge. Diuretics reduce preload, ACE inhibitors lower afterload, beta blockers reduce sympathetic activity, and digitalis has inotropic effects. Newer medications target vasodilation and myosin activation to improve heart efficiency while lowering energy requirements. Combination therapy, following an assessment of cardiac function and volume status, is the most effective strategy to heart failure care.

3. Introduction
A beautiful confident smile is desired by all.
When a patient wishes to attain that smile but is skeptical to
undertake the treatment procedure, for not being able to visualize
his or her treatment outcome, is when, a clinician can use the
Digital smile designing (DSD) tool.
DSD concept aims to help clinician by improving the aesthetic
visualization of the patient's concern, giving understanding of the
possible solution therefore educating and motivating them about the
benefits of the treatment and increasing the case acceptance.
4. Digital smile design is a digital mode that help us to create and
project the new smile design by attaining a simulation and pre
visualization of the ultimate result of the proposed treatment.
A design created digitally involves participation of the patients on
the designing process of their self-smile design, leading to
customization of smile design as per individual needs and desires.
It complements with the morpho psychological characteristics of
the patient, relating patient to an emotional level, increasing their
confidence in the process and better acceptance of the anticipated
treatment.

16. Procedure
Facial analysis is done using reference lines from which uniform
parameters are developed for frontal view of the face.
The horizontal reference lines consist of the inter-pupillary and
inter-commissural lines that deliver a complete sense of balance and
horizontal over view in the aesthetically pleasing face.
While the vertical reference line includes the facial midline,
passing the glabella, nose, and the chin .
17. The horizontal and vertical lines are crossed against each other to
measure symmetry .
The facial photograph with a wide smile and the teeth apart is
moved behind this cross to determine the ideal horizontal plane and
vertical midline which permits a comparative analysis of the teeth
and face.
18. After facial analysis, dento gingival analysis is done.
The length of the upper lip at rest and in a smile is checked to
determine the gingival display.
Smile curve is established by correlating the curvature of the incisal
edges of the maxillary anterior teeth.
The dental contour is made according to the lower lip proportions
and the anterior-posterior curvature of the teeth.
This facial photograph is then cropped to show only the intraoral
view.
Three reference lines are marked on the teeth, a straight horizontal
line drawn from canine tip to canine tip, one more horizontal line on
the incisal edges of central incisors and another vertical line passing
through the dental midline (passing through theinterdental papillae).
19. This supports in reproducing the cross, that is, the reference inter-
pupillary and facial midline on the face onto the intraoral view.
Few additional lines are drawn such as the gingival zenith,joining
lines of the gingival and incisal battlements for complete dental
analysis.
For adequate teeth dimension the ideal size of dental width to length
ratio can be incorporated by any one of the published theories
which includes Golden proportion,Pound's theory,Recurring
aesthetic dental proportion, or Visagism
20. Required changes are carried out with the help of a digital ruler
which can be calibrated on the photograph by measuring the width
of the central incisors in the study model.
Changes can be modified, decreased or adapted to different
situations, depending on the aesthetic requirement and individual
needs of the patient.
21. After the new smile design is attained it can be digitally presented
to the patient to seek out appreciation and feedback.
This digitally approved smile design at this stage can be used to
create physical mockup which can be tested aesthetically in the
patient's mouth.
The mock-up allows for not only visualization of the shape
integrated to the gingiva,lips, face, but also to phonetics during the
evaluation period.

23. Advantages
Digital analysis visualization.
Diagnosis and treatment planning.
Customization.
Communication.
Medico-legal functions.
25. Future
prospects
With the improvements in the software over the next few years, it
will be possible to address facial aesthetics in advanced cases where
implants need to be placed by superimposing the files coming from
a CT scan or a Cone Beam, along with 3D files of an oral
impression or a facial scan and a photo.
There also is a possibility of incorporating 4D concept in which
motion can be added to the smile design concept.
26. With ever evolving fast paced technology a time, not so far, may
come, when digitally designed smile can be projected to virtual
reality glasses to foresee the desired smile in actual reality.
27. Review of
Literature
Chetan et al in 2023, had conducted a study on assessment
of Patient Satisfaction and Treatment Outcomes in Digital
Smile Design vs. Conventional Smile Design
He had concluded that patients in the DSD group exhibited
excellent restoration fit, occlusion, and esthetics
emphasizing potential advantages of integrating digital
technology into smile design procedures.
28. Conclusion
Helpful tool in aesthetic visualization.
Improves clinician's diagnosis and treatment planning.

Editor's Notes
Coachman and Calamita described DSD as a multi-use conceptual tool that can support diagnostic vision, improve communication, and enhance treatment predictability, by permitting careful analysis of the
patient's facial and dental characteristics that may have gone unnoticedby clinical, photographic or diagnostic cast based evaluation procedures.
In the last two decades smile designing has progressively evolved from physical analogue to digital designing which has advanced from 2D to 3D
Christian Coachman in 2017 has proposed this evolution in generations as:
DSD technique is carried out by digital equipment already prevailing in current dental practice like a computer with one of the DSD
Software. An accurate photographic documentation is essential as complete facial and dental analysis rests on preliminary photographs on which changes and designing is formulated, a video documentation required for dynamic analysis of teeth, gingiva, lips and face during smiling, laughing andtalking in order to integrate facially guided principles to the smile design
To proceed with a correct digital planning it is crucial to follow a photography protocol. Photographs taken should be of utmost quality and precision, with correct posture and standardized techniques, as
facial reference lines like the commissural lines, lip line and inter-pupillary line which forms the basis of smile designing are established on them. Poor photography misrepresents the reference image and may
lead to an improper diagnosis and plannin
According to Coachman during videography best framing and zoom should be adjusted with suitable exposure and focus adjusted to mouth. For ideal development of the facially guided smile frame, four
videos from specific angles should be taken:
Factors such as dentofacial aesthetic parameters, ease of use, case documentation ability, cost, time efficiency, systematic digital workflow and organization, and compatibility of the program with CAD/
CAM or other digital systems may influence the user's decision
Although the inclusion of aesthetic parameters in different DSD software varies, basic procedure of smile designing remains the same. All the DSD software allows for aesthetic designing through the drawing of reference lines and shapes on extra- and intraoral digital photographs
Patients can view their rehabilitations even before they start, and this can also have important medico-legal functions.
2.As the diagnosis and treatment plan depends on photographic and video documentation, inadequacy in them may distort the reference image and may result in an incorrect diagnosis and planning
2.For complete 3D digital work flow,
3.Training and handling for certain software are necessary which
Complete 3D digital workflow is still not extensively used which in future may come into practice far and wide when more and more clinician will adopt digital scanner, 3D printers, CAD/CAM, then the need for time-consuming impressions, plaster and wax will become far less necessary.
It not only helps patients to envision their treatment outcome but also improves clinician's diagnosis and treatment planning
