Teeth selection for complete dentures involves considering several factors to ensure function and aesthetics. Size is based on facial measurements and residual ridge contours. Form depends on facial profile, sex, age and personality. Color should harmonize with complexion. Anterior teeth material is typically porcelain or acrylic. Posterior teeth shade matches anterior teeth and form depends on occlusion type. Anatomic teeth are more aesthetic but non-anatomic teeth are more comfortable in resorbed ridges. Proper teeth selection improves denture function and patient confidence.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:

Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS
New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
9. 1.WHITE’S CONCEPT
J W White in 1872 – projected correspondence and harmony theory,
temperamental theory was fading out of medicine but white reached over
and suggested that temperaments called for similarity of form in faces
and teeth.
• The temperamental theory is a theory of fluids of the body, especially the
blood ,the phlegm and the bile.
It was conceived by the Hippocrates in 5th century BC and was used by
the medical profession in diagnosis and treatment planning.
10. The Psychological Effects of the Humors
The Four Humors are not just gross, physical
substances. They also pervade the whole organism
as subtle vapors, even affecting the mind,
thoughts, and emotions.
And so, the Four Humors also have psychological
effects, making them capable of affecting both
body and mind:
11.
Blood promotes a feeling of joy, mirth, optimism, enthusiasm,
affection and wellbeing.
Phlegm induces passivity, lethargy, subjectivity, devotion,
emotionalism, sensitivity and sentimentality.
Yellow Bile provokes, excites and emboldens the
passions. Being inflammatory, irritating and caustic, it provokes
anger, irritability, boldness, ambition, envy, jealousy and courage
.
Black Bile makes one pensive, melancholy and withdrawn. It
encourages prudence, caution, realism, pragmatism and
pessimism.
The Four Humors tend to have negative effects on the mind and
emotions only when they're excessive or aggravated. Otherwise,
they can also strengthen positive aspects of character.
12. FOUR TYPES OF TEMPERAMENT-
1. Sanguine, ಆಶಾವಾದಿಯಾದ
2. Nervous,(phlegmatic) ಸುಸ್ತಿನ-ಕಫ-
3. Bilious (choleric) ಸ್ತಟ್ಾಾಗುವ
4. Lymphatic(melancholic) ಖ ೇದ

14. Artificial teeth ---- patient’s temperament.
• A ‘‘bilious’’ short, broad, tapering
incisor teeth,
• A sanguineous long, thin, and narrow
teeth
18. DENTOGENIC CONCEPT-BY FRUSH &FISHER
•AGE, SEX AND PERSONALITY of the patient •
Frush and Fisher 1955. Frush JP, Fisher DR (1955) Introduction to
dentogenic restorations. J Prosthet dent 5:586–595
21. 3. WINKLER’S CONCEPT
This concept emphasises on three points.
1.BIOLOGICAL-PHYSIOLOGICAL
harmony of the facial musculature and physiological limit
with teeth arrangement.
2.•BIOMECHANICAL
mechanical limitations in placement of anterior teeth.
3• PSYCHOLOGICAL
aesthetics and facial appearance of psychological
plane of orientation
Raised in happy people—lowered in poor mental
temperament
22. ANTERIOR TOOTH SELECTION WINKLER'S CONCEPT
• Psychological •
Camper’s line is the psychological plane of orientation
• It is raised in happy people
• It is tilted in depressed people
• Biomechanical • According to this teeth should be set in
the neutral zone
23. LEON WILLIAM’S CONCEPT
4.
Since 1885 J. Leon Williams,later in 1909 he proposed the
technique to build wax occlusal rims of proper height and
form, with patient’s lips at rest, marked the location of corner
of mouth ,high lip line, lower lip line ,and after removing the
occlusal rim the distal end of second molar is marked.
Williams did an extensive study in 1914 to give three basic
typal forms – ovoid, tapering, square.
24. According to him it was “combination forms”
tapering or ovoid or both in blended into
square Square or ovoid or both in blended
into tapering Square or tapering or both
inbleded into ovoid
25. TOOTH FORM CAN ALSO BE SELECTED BASED ON THE ARCH FORM
OF THE PATIENT
26.
27. FACTORS FOR ANTERIOR TEETH SELECTION
1.SIZE OF THE TEETH
2.FORM OF THE TEETH
3.COLOUR OF THE TEETH
4.COMPOSITION OF MATERIAL OF THE TEETH
28. SIZE OF THE TEETH
1.PRE EXTRACTION 2.POST EXTRACTION
1. PRE EXTRACTION RECORDS
•PHOTOGRAPHS –WIDTH OUTLINE FORM
•RADIOGRAPHS –size & form
•EXTRACTED TEETH-execellent size &form
•PREVIOUS DENTURE

29. SIZE OF THE TEETH
2. POST EXTRACTION
A• EXTRAORAL FACTORS:-
1. SIZE OF THE FACE
2. THE LIPS
3. MAXILLO MANDIBULAR RELATION
4. NOSE WIDTH
B• INTRAORAL FACTORS:-
1. SIZE OF MAXILLARY ARCH
2. INCISIVE PAPILLAE AND CUSPID EMINENCE
3. THE CONTOUR OF THE RESIDUAL RIDGE
4. VERTICAL DISTANCE BETWEEN THE RIDGES
30. 1. SIZE OF THE FACE
• Average width of the maxillary central incisor = 1/16th of
the width of the face measured between the zygoma.
• Combined width of the six maxillary anterior teeth = slightly
less than 1/3rd of the bizygomatic breadth of the face.
• The TRUBYTE® TOOTH INDICATOR
size of maxillary central incisors

32. 2.SIZE OF MAXILLARY ARCH
• The mould selectors are used to make measurements of
the maxillary cast.
crest of the incisive papilla TO hamular notches,
hamular notch TO opposite side hamular notch.
• The combined length of the three legs of the triangle in
millimetres is used.
33. 3.PAPILLAE AND CUSPID
EMINENCE
• Canine eminence…
• A flexible ruler is used and the distance between the two
canine eminences at their distal side through the anterior
of the incisive papilla is measured in millimetres.
• This measurement gives the combined width of the six
anterior teeth.
• Another method with occlusal rim
• The vertical line drawn from this mark coincides with the
pupil of the eye. • The distance between the marks
following the contour is the total width of anteriors.
34. 4. MAXILLO MANDIBULAR RELATION
• Any disproportion in size between the maxillary and
mandibular arches influences the length, width and position
of the teeth.
• This is of importance in class ii and class iii
maxillomandibular relations.
If mandible is protruded; anterior teeth are larger,
if mandible is retruded; anterior teeth are smaller.
35. 5.THE CONTOUR OF THE RESIDUAL RIDGE
• The artificial teeth should
follow the contour of the residual ridges that existed
when natural tooth were present.
• As resorption occurs there is alteration in the contours of
the ridge.
36. 6.VERTICAL DISTANCE BETWEEN THE
RIDGES
• The length of the teeth is determined by the
available space between the existing ridges.
• It is advisable to use a tooth long enough to
eliminate the display of the denture base.

5. PERSONALITY
40. 1.FORM AND CONTOUR
• The shape of the artificial tooth should harmonise with the
patient’s facial form . • By Leon Williams,
• Not scientifically correct, is undoubtedly the simplest and the
most useful guide.
• Shape of the upper incisors the shape of the face.
• He classified the form of the human face into three types:
square, tapering and ovoid forms.
HE FACIAL FORM IS DETERMINED BY USE OF TRUBYTE
INDICATOR
41. 2.FACIAL PROFILE
• THE FACIAL PROFILE IS DETERMINED BY THREE
POINTS.
1. THE FOREHEAD,
2. THE BASE OF THE NOSE AND
3. THE PROMINENT POINT OF THE CHIN
42. 3.SEX
• Curved facial features are associated with femininity
and square features are associated with masculinity.

PEOPLE
Lighter shade Darker shade More incisal translucency Less
incisal translucency Minimal wear of incisal edges Increased
wear of incisal edges Curved smiling line Flat smiling line
Pointed canines Loss of tip of canines
45. 5.PERSONALITY
• Teeth should be selected according to the patients
personality • The patients
• vigorous
• delicate.
• More squarish and large teeth vigorous people.
• The anteriors should be in flat plane for executive people
• For executives teeth should be relatively smaller and
more symmetrical
51. In general Color or shade of anterior teeth Patients
age – With age, darker, while lighter teeth
are suitable for young patients.
Patients complexion—light teeth for fair skin,
blue eyes, dark teeth usually for dark skin
and black eyes.
54. Shade selection involves the perception of color,
which depends on three entities:
Illumination.
The environment.
The viewer.
55.
56. COMPOSITION OF MATERIAL OF
ANTERIOR TEETH
•Usually only two types of materials are used
1.Porcelain
2.Acrylic •
HMW resin because of
• Exceptional hardness
• Stable colour.
• Abrasion resistance
• Less retention of plaque
57. ACRYLIC TEETH/ PORCELAIN TEETH
Wear is clinically significant
Loss of vertical dimension
Have a soft impact sound
Easy to grind and alter
Does not bind to denture base
material need to create holes or
pins
Does not cause abrasion of
opposite natural teeth
1.When the opposite archteeth
have gold crowns or inlays.
2.Decreases inter arch distance;
the resin teeth help to grind and
accommodate into the free
space.
3.In removable partial denture,
the contacting teeth with the
clasps may need grinding.
Wear is clinically insignificant
No significant loss of vertical
dimension
Have a sharp impact sound
Difficult to grind and fit into
close interarch space
Chemically bonds to the
denture base material
Causes abrasion of opposite
natural or gold teeth
Indications 1. When interridge
space is present.
2. Well configured ridges
3.When high appealing look is
required.
58. POSTERIOR TOOTH SELECTION
1.SHADE OF POSTERIOR TEETH
2.SIZE AND NUMBER OF POSTERIOR TEETH
3.FORM OF POSTERIOR TEETH
1.SHADE OF POSTERIOR TEETH
• The shade of posterior teeth should harmonize to shade
of anterior teeth
• As bulk influences shade of teeth
• So lighter shade for bicuspids if it is used as aesthetic
purpose.
• Slightly lighter than posterior teeth but not lighter than
anterior teeth.
59. 2.SIZE AND NUMBER OF POSTERIOR
TEETH
• The size and number are closely related to usage
• Buccolingual dimension should be less than natural teeth
• Anterio posterior dimension is determined by the
edentulous area between cuspids and the area slightly
anterior to retromolar area.
• Not necessary to have the same number of teeth as in
natural dentition.
60. 3. FORM OF POSTERIOR TEETH
Occlusal form decided on the type of occlusion.
Types of teeth to be used :-
1. Balancing in centric and eccentric cusp form tooth
2. Disocclude during eccentric jaw movements cusp
or monoplane teeth
3. Arranged in a plane and balanced only in centric
monoplane is used
61.
62. ADVANTAGES /DISADVANTAGES OF ANATOMIC TEETH
Advantages
1.Aesthetically acceptable
2.More efficient there by reducing the forces
3.They can be arranged in balance
Disadvantages of anatomic teeth
1.More horizontal forces during function
2.Fast bone resorbtion
3.Cannot be used in severely resorbed cases
63. ADVANTAGES /DISADVANTAGES OF NON ANATOMIC
TEETH
1.Comfortable
2.Greater range of motion (in parafunctional jaw
habits)
3.Less horizontal and or torqueing forces
4.Can be used in severely resorbed ridges and
patients with poor neuro muscular coordination
Disadvantages of non anatomic teeth
