Dentin hypersensitivity is sharp, short pain from exposed dentin in response to stimuli like heat, cold, sweet or sour foods, or brushing. It occurs when gum recession exposes dentin tubules. The hydrodynamic theory is the leading explanation, where stimuli cause dentin fluid flow, activating nerve fibers. Treatment focuses on plugging tubules, desensitizing nerves, or applying varnishes. At-home options include potassium nitrate toothpastes while in-office options range from fluoride to lasers. Patient education helps manage the condition.

An unsettling discomfort when a cold drink hits your teeth usually means one thing: tooth hypersensitivity or as many prefer to call it ‘sensitive teeth’. For some people, citrus fruits and other acidic foodstuffs are avoided like the plague as they bring on discomfort. Some even dread speaking if it’s too windy or cold outside.
Hypersensitivity can make something as routine as eating unnecessarily difficult. However, there are a number of solutions available which promise to restore normalcy to your teeth and make eating (and speaking, regardless of the weather outside) much more enjoyable.

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.

Microteaching is a unique model of practice teaching. It is a viable instrument for the. desired change in the teaching behavior or the behavior potential which, in specified types of real. classroom situations, tends to facilitate the achievement of specified types of objectives.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

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

2. Dentin
hypersensitivity
prepared by: Dr. Muneera Ghaithan
3. definition
It’s defined as sharp ,short pain arising from
exposed dentin in response to stimuli typically
thermal, chemical, tactile or osmotic and
which can not be ascribed to any other form
of dental defect or pathology.
It’s a symptom complex rather than a true
disease
5. The neurophysiology of teeth
• Both myelinated and unmyelinated axons
innervated the pulp.
• According to conduction velocities the nerve
units can be classified into:
Having conduction velocity
A group > 2 m/s
Having conduction velocity
C group < 2 m/s
6. • Aδ fibers ( C.V≈6-30 m/s) are responsible for
sharp better localized pain.
• While C fibers are considered responsible for
dull radiating pain
Myelinated A fiber seems to be responsible
for dentin sensitivity.
7. • It is well known even the most peripheral
part of dentin is sensitive.
However, varying opinions have been
presented on the mechanism of
intradental nerve activation in response to
external irritation.
8. Mechanism of dentin sensitivity
Theories of dentin sensitivity:
A. Neural theory
B. Odontoblastic theory
A. The hydrodynamic theory
B. Modulation theory
9. Neural theory
Activation to initial excitation of
these nerve ending in dentinal
tubules
nerve signals are conducted
along the parent primary
afferent nerve fibers.
Dental nerve branch.
brain
10. a recent neuroanatomic studies -
Byer (1984) have shown that
only the inner 100 to 200 µm of
dentin is innervated, indicating
that the pain sensations induced
by stimulation of superficial
dentin cannot be a result of
direct irritation of nerve ending.
11. Odontoblastic theory
The theory assumed that odontoplast
extend to the periphery.
Stimuli
Excite the process or body of
odontoplast.
The membrane of odontoblasts come
into close apposition with that of the
nerve ending in the pulp or in D.T.
The odontoblast transmets the
excitation of these nerve endings
12. Thomas (1984) indicated that the
odontoblastic process is restricted to the inner
third of the dentinal tubules. Accordingly it seems
that the outer part of the dentinal tubules
doesnot contain any cellular elements but is only
filled with dentinal fluid.
13. The hydrodynamic theory
This theory proposes that:
Stimuli
Displacement of fluid that exists
in the dentinal tubules
Activates the nerve endings
present in the dentin or pulp
14.
15. The displacement of
the tubule contents
is rapid enough to
deform nerve fiber in
pulp or predentin or
damage odontoplast
cell. Both of these
effects appear
capable of producing
pain.
17. Etiology and predisposing factors
The primary underlying cause for DH is exposed
dentin tubules
Loss of covering periodontal
structures
Dentin may be
exposed by:
Loss of enamel
18. The area of recession that has developed due to a combination
of age-related changes, and history of gum disease (light blue).
The dark blue area has a white filling which may have been
placed there to treat dentine hypersensitivity.
19. Common Reasons for Gingival
Recession
1. Inadequate attached gingiva
2. Prominent roots
3. Toothbrush abrasion
4. Pocket reduction periodontal surgery
5. Oral habits resulting in gingival
laceration, i.e., traumatic tooth picking eating hard
foods
6. Excessive tooth cleaning
7. Excessive flossing
8. Gingival loss secondary to specific diseases, i.e.
periodontitis, herpetic gingivostomatitis
9. Crown preparation
21. anatomical characteristics in the region
of cementum–enamel junction (CEJ),
overlapping edge-to-edge not form a junction
22. Diagnosis
The pain arising from DH is extremely variable
in character, ranging in intensity from mild
discomfort to extreme severity.
The degree of pain varies in different teeth and
in different persons.
It may emanate from one tooth or several teeth
and it is sometimes felt in all quadrants of the jaws
23. Most patients describe the pain arising from
DH as being rapid in onset, sharp in
character, and of short duration ( the character
of pain doesn't outlast the stimulus).
The pain is intensified by thermal
changes, sweet, sour, scratching the dentine.
24. Diagnosis and treatment
Making the proper diagnosis is the first step in
assisting your patients suffering from dentin
hypersensitivity.
26. Management and Treatment
• Addressing any underlying causes of dentin
hypersensitivity is the first step in successfully
managing the condition.
• Educating the patient on the causes and
management of dentinal hypersensitivity.
• Treatment options include both in-office
procedures and at-home care.
Generally, the least invasive treatment method
should be considered first.
27. Management and Treatment
• Three principal treatment options:
1. Dentinal tubules can be covered
2. Dentinal tubules can be plugged
3. Desensitization of the nerve tissues
within tubules
28. Management and Treatment
At-home treatments:
• At-home treatments include desensitizing
toothpastes or dentifrices
1. Desensitize the nerve
a) Potassium Nitrate:
interfere with the transmission
of the nerve impulse
Potassium nitrate is commonly
used in toothpastes such
as Sensodyne or Crest
Sensitive as a remedy
29. Management and Treatment
2. Plug (sclerose) the dentinal tubules:
a) Strontium chloride and strontium acetate
form mineralised deposits
within the tubule lumen and
on the surface of the exposed
dentine, they are used in
Sensodyne Original and
Sensodyne Mint toothpastes.
b) Fluoride dentifrices
Note the occlusion of the dentinal tubules,
preventing the outward flow of fluid and
subsequent stimulation of nerve fibers.
30. Management and Treatment
In-office procedures
1- Desensitize the nerve:
potassium nitrate
2- partially obturate the dentinal tubules
a) stannous fluoride.
b) potassium oxalate.
c) strontium chloride.
d) calcium compounds.
31. 3- Tubule sealant
• A) restorative resins.
• B) dentin bonding agents.(GLUMA)
4- Cavity varnish
5- Laser
32. Management and Treatment
Patient education
• Causes of dentinal hypersensitivity
• Instructions on tooth brushing technique and when
to brush.
• Advice on toothbrush type - avoid medium and
hard bristles
• Advice on appropriate use of toothpaste
• Advice on technique for interdental cleaning
• Dietary advice
• Hypersensitivity associated with tooth whitening
