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

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
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

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!

4. SHAPE OR FORM
• Determines the esthetic appearance of teeth.
• FEMININE SMILE:
• Rounded incisal angles,
• Open incisal and facial
embrasures,
• Softened facial line
angles.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
5. • MASCULINE SMILE:
• Less rounded incisal angles.
• Closed embrasures
• COSMETIC RECONTOURING:
Minor modifications of existing tooth
contours can effect a significant esthetic
change .
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
6. • Reshaping enamel by rounding incisal angles,
opening incisal embrasures, and reducing
prominent facial line angles can produce a more
feminine, youthful appearance.
• Restoring an individual tooth rather than all
anterior teeth simultaneously may require
greater artistic ability.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
7. • ILLUSIONS OF SHAPE:
• Border outline of an anterior tooth is primarily
two dimensional (i.e, Length and Width)
• Third dimension of Depth becomes crucial
when creating illusions.
• By controlling the areas of light reflection and
shadowing a natural appearance can be given
to restorations.

8. LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
9. SYMMETRY AND PROPORTIONALITY
• Dental symmetry can be maintained if the sizes of
the contralateral teeth are equivalent.
• In addition to being symmetric, anterior teeth must
be in proper proportion to one another to achieve
maximum esthetics.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
10. The concept of the Golden proportion:
• Based on this formula, a smile, when viewed
from the front, is considered to be esthetically
pleasing if each tooth in thatsmile (starting from
the midline) is approximately 60% of the size of
the tooth immediately mesial to it.
• The exact proportion of the smaller tooth to the
larger tooth is 0.618.
• In a typical esthetically pleasing smile, the
maxillary anterior teeth are generally in golden
proportion to one another

DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
11. LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
12. POSITION AND ALIGNMENT
• The overall harmony and balance of a smile
depend largely on proper position of teeth
and their alignment in the arch.
• Malposed or rotated teeth disrupt the arch
form and may interfere with the apparent
relative proportions of the teeth.
13. SURFACE TEXTURE
• The character and individuality of teeth are
determined largely by the surface texture and
characteristics that exist.
• E.g. Teeth in young individuals
characteristically exhibit significant surface
characterization, whereas teeth in older
individuals tend to possess a smoother surface
texture caused by abrasional wear.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
14. COLOR
• Color is the most complex artistic element. It
is an area in which numerous interdependent
factors exist, all of which contribute to the
final esthetic outcome of the restoration.
• Teeth typically are composed of a multitude
of colors. A gradation of color usually occurs
from gingival to incisal, with the gingival
region being typically darker because of
thinner enamel.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
15. • An understanding of normal tooth coloration
enhances the dentist’s ability to create a
restoration that appears natural.
• Accurate shade selection is best attained by
applying and curing a small amount of the
composite restorative material in the area of
the tooth anticipated for restoration.
• Shade selection should be determined before
isolating the teeth to avoid color variations
that can occur as a result of drying and
dehydration of the teeth.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
16. TRANSLUCENCY
• Translucency affects the esthetic quality of the
restoration.
• The degree of translucency is related to how
deeply light penetrates into the tooth or
restoration before it is reflected outward.
17. CONSERVATIVE TREATMENT FOR
DISCOLOURED TEETH
• It includes:
1.Removal of surface stains.
2.Bleaching
3.Macroabrasion
4.Microabrasion
5.Veneering
6.Placement of porcelain crowns
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
21. • Intrinsic Discolorations:
• it can affect vital or non vital teeth and also
root canal treated teeth.
• It can be either localised or generalised.
• Etiology:
1.Hereditary disorders
2.Medications
3.Excess flourides
4.High fever associated with early childhood
illnesses
5.Other types of trauma
22. • Treatment:
1. Bleaching
2. Microabrasion
3. Macroabrasion
4. Veneering
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
23. BLEACHING TREATMENTS
• The lightening of the color of a tooth through the
application of a chemical agent to oxidize the organic
pigmentation in the tooth is referred to as bleaching.
Bleaching techniques may be classified:
• whether they involve vital or nonvital teeth, and
• whether the procedure is performed in the office or
outside the office.
• The mechanism of action of bleaching teeth with
hydrogen peroxide is considered to be oxidation of
organic pigments
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
24. NON VITAL BLEACHING PROCEDURES
Causes:
1.Bleeding into dentin as a result of trauma
before RCT.
2.Degradation of pulp tissue left in chamber
after such therapy
3.Staining from restorative materials and
cements placed in the tooth as a part of RCT.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
25. • Nonvital bleaching techniques include an in-
office technique and an out of the office
procedure referred to as walking bleach.
• In Office Non Vital Bleaching Technique:
• Historically comprised of A thermocatalytic
technique consisting of the placement of 35%
hydrogen peroxide liquid into the debrided pulp
chamber and acceleration of the oxidation
process by placement of A heating instrument
into the pulp chamber.
• A more contemporary technique uses 30% to
35% hydrogen peroxide pastes or gels that
require no heat.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
26. • In both techniques, it is imperative that a
sealing cement placed over the exposed root
canal filling before application of the
bleaching agent to prevent leakage and
penetration of the bleaching material in an
apical direction.
• The bleaching agent should be placed in the
coronal portion of the pulp chamber to
prevent unwanted leakage of the bleaching
agent through lateral canals or canaliculi to
the periodontal ligament.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
27. • Walking Bleach
• isolate the discolored tooth and remove all
materials in the coronal portion of the tooth.
• Remove gutta-percha (to approximately 1-2
mm apical of the clinical crown)
• enlarge the endodontic access opening
sufficiently to ensure complete debridement
of the pulp chamber.
• place a resin-modified glass-ionomer liner to
seal the gutta-percha of the root canal filling
from the coronal portion of the pulp chamber.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
28. • After the seal hardens, trim any excess material
from the seal so that the discolored dentin is
exposed peripherally.
• Sodium perborate is used with this technique.
• Using a cement spatula with heavy pressure on a
glass slab, one drop of saline or sterile anesthetic
solution is blended with enough sodium
perborate to form a creamy paste.
• A spoon excavator or similar instrument is used
to fill the pulp chamber (with the bleaching
mixture) to within 2 mm of the cavosurface
margin, avoiding contact with the enamel
cavosurface margins of the access opening.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
29. • a cotton pellet is used to blot the mixture and a
temporary sealing material is used(e.g.,
Intermediate Restorative Material or Cavit) to
seal the access opening.
• Sodium perborate should be changed weekly
until desired result is achieved.
• The chamber is rinsed and filled to within 2 mm
of the cavosurface margin with a paste consisting
of calcium hydroxide powder in sterile saline.
• Allow calcium hydroxide to remain in the pulp
chamber for 2 weeks and then clean the cavity by
removing all the temporary restoration seal the
cavity with composite.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
30. VITAL BLEACHING PROCEDURES
• INDICATIONS:
• intrinsically discolored teeth from aging,
trauma, or drug ingestion.
• before and after restorative treatments to
harmonize shades of the restorative materials
with the natural teeth.
• Teeth exhibiting yellow or orange intrinsic
discoloration
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
31. • Vital bleaching techniques include an in-office
technique referred to as power bleaching
• and an outside the office alternative that is a
“dentist-prescribed, homeapplied”technique
(i.e., nightguard vital bleaching, or simply “at-
home bleaching”)
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
32. • In-Office Vital Bleaching Technique.
• requires excellent rubber dam technique and
careful patient management.
• Vaseline or cocoa butter may be placed on
the patient’s lips and gingival tissues
• application of the rubber dam to help
protect these soft tissues from any
inadvertent exposure to the bleaching agent.
• Bleaching agent: Most consist of paste or gel
compositions that most commonly contain
30% to 35% hydrogen peroxide.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
33. • The dentist places the hydrogen peroxide–
containing paste or gel on the teeth.
• On completion of the treatment, the dentist
rinses the teeth,
• removes the rubber dam or isolation medium,
and cautions the patient about postoperative
sensitivity.
• Bleaching treatments generally are rendered
weekly for two to six treatments, with each
treatment lasting 30 to 45 minutes.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
34. Dentist-Prescribed, Home-Applied
Technique
• Also known as night guard vital bleaching
• Less labour intensive and requires less in office
time
• An alginate impression of the arch to be treated
is made and poured in cast stone.
• The dentist trims the cast around the periphery
to eliminate the vestibule and thin the base of
the cast palatally.
• The dentist allows the cast to dry and blocks out
any significant undercuts using a block-out
material.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
35. • The nightguard is formed on the cast using a heated
vacuum-forming machine.
• After the machine has warmed up for 10 minutes, a
sheet of 0.020 to 0.040 inch (0.75-1.5 mm) soft vinyl
nightguard material is inserted and allowed to soften
by heat until it sags approx. 1 inch.
• The top portion of the machine is closed slowly and
gently, and the vacuum is allowed to form the heat-
softened material around the cast.
• After sufficient time for adaptation of the material,
the dentist turns off the machine and allows the
material to cool.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
36. • the dentist uses scissors or a No. 11 surgical
blade in a Bard-Parker handle to trim in a
smooth,straight cut about 3 to 5 mm from the
most apical portion of the gingival crest of the
teeth.
• Excess material is removed.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
37. • Scalloped design is preferred as it allows the
tray to cover only the teeth and prevents
entrapment of the bleaching material
between the gingival tissue and the
nightguard.
• The dentist inserts the nightguard into the
patient’s mouth and evaluates it for
adaptation, rough edges, or blanching of
tissue.
• A 10% to 15% carbamide peroxide bleaching
material generally is recommended for this
bleaching technique.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
38. • Carbamide peroxide degrades into 3%
hydrogen peroxide (active ingredient) and 7%
urea.
• The patient is instructed in the application of
the bleaching gel or paste into the nightguard.
• If the nightguard is worn at night, a single
application of bleaching material at bedtime is
indicated.
• In the morning, the patient should remove the
nightguard, clean it under running water with
a toothbrush, and store it in the container
provided.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
39. • Total treatment time using an overnight
approach is usually 1 to 2 weeks.
• It is recommended that only one arch be
bleached at a time, beginning with the
maxillary arch.
• Tetracycline-stained teeth typically are much
more resistant to bleaching.
LRM 3 BDS IV YEAR CURRICULUM DEPARTMENT OF CONSERVATIVE
DENTISTRY AND ENDODONTICS MANAV RACHNA DENTAL COLLEGE
40. MICROABRASION
• Conservative alternative for the removal of
superficial discolorations.
• Microabrasion involves the surface dissolution
of the enamel by the acid along with the
abrasiveness of the pumice to remove
superficial stains or defects.
• Acid used is 11% HCl.
• Usually indicated for non hereditary
dysmineralization defects

42. MACROABRASION
• An alternative technique for the removal of
localized, superficial white spots and other
surface stains or defects is called
macroabrasion.
• uses a 12-fluted composite finishing bur or a
fine grit finishing diamond in a high-speed
handpiece to remove the defect.

44. VENEERS
• A veneer is a layer of tooth-colored material that
is applied to a tooth to restore localized or
generalized defects and intrinsic discolorations.
• Veneers can be either direct or indirect veneers.
• Indirect veneers include processed
composite,porcelain or pressed ceramic
materials.
• Two types of esthetic veneers exist:
1.Partial veneers
2.Full veneers

46. • Partial veneers are indicated for the
restoration of localized defects or areas of
intrinsic discoloration.
• Full veneers are indicated for the restoration
of generalized defects or areas of intrinsic
staining involving most of the facial surface of
the tooth.

49. • When only a few teeth are involved, or when the
entire facial surface is not faulty (i.e., partial
veneers), directly applied composite veneers can be
completed chairside for the patient in one
appointment.
• Indirect veneers require two appointments, but
typically offer three advantages over directly placed
full veneers, as follows:
1. Indirectly fabricated veneers are much less sensitive
to operator technique. Considerable artistic
expertise and attention to detail are required to
achieve esthetic and physiologically sound direct
veneers consistently

50. Indirect veneers are made by a laboratory
technician and are typically more esthetic.
2. If multiple teeth are to be veneered, indirect
veneers usually can be placed much more
expeditiously.
3. Indirect veneers typically last much longer
than direct veneers, especially if they are
made of porcelain or pressed ceramic.

51. • Two basic preparation designs exists for full
veneers:
1.Window preparation:
• it is recommended for most direct and
indirect composite veneers.
• This intraenamel design preserves the
functional lingual and incisal surfaces of the
maxillary anterior teeth, protecting the
veneers from significant occlusal stress.
• By using a window preparation,the functional
surfaces are better preserved in enamel.

52. 2.Incisal,lapping preparation:
• It is indicated when the tooth being veneered
needs lengthening or when an incisal defect
warrants restoration.
• This design is used frequently with porcelain
veneers because it not only facilitates
accurate seating of the veneer on
cementation,but it also allows for improved
esthetics along the incisal edge.
