1. Dentures need to be relined periodically, usually every 2-3 years, to account for residual ridge resorption which causes dentures to become loose.
2. The relining process involves taking a new impression using the existing denture and replacing the impression material with denture base material in the lab.
3. Common materials used for the relining impression include zinc oxide eugenol, rubberbase impressions, and tissue conditioners. The functional reline technique uses tissue conditioners.

this contains the steps for the class 1 cavity preparation for amalgam in detail. also contains the difference between composite and amalgam cavity preparation.
Currently, complete dentures are mainly designed and fabricated using conventional methods, which involve a broad series of clinical and laboratory procedures.
Dentists may want to consider using an update of a unique complete denture technique that saves total chair time and, therefore, decreases cost.
It is possible to fabricate a complete denture with different techniques in minimal visit. These techniques has positive benefits saving a lot of time and materials for both the patient and the clinician.
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!

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

Title: Sense of Smell
Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
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:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
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
1. Relining & Rebasing
3rd year Revision class
by Dr Sushen sharma
Sr Lecturer, Manav Rachna Dental College
2. • Due to Residual ridge resorption, the residual
ridges shrink & the dentures become loose
over a period of time.
• Thus, dentures need to be relined periodically
(every 2-3 years) in order to fill this gap
between the altered tissue contours of oral
cavity and the existing intaglio denture
surface.
3.
4. Relining / rebasing procedure consists of 2
separate procedures
1. Making of new impression using the existing
denture : Relining impression
2. Replacing the impression material with
denture base material : Laboratory
processing of the relined impression
5. Relining impression material can be
1. Zinc oxide eugenol
2. Rubberbase impression materials
3. Tissue conditioners
4. Mouth temperature waxes
6. Steps in relining impression:
1. Denture preparation : trimming borders &
intaglio surface of existing denture by 1.5-
2.0mm. Hole in palate & labial flange to ovoid
increase in V.D
2. Border moulding : using green stick on flat &
trimmed borders.
3. Impression making : using ZnOE/ Light body etc
7.
8. Functional reline Technique
When tissue conditioners or mouth temperature waxes are
used for relining impression, the technique is called as
Functional Reline.
Most commonly, tissue conditioners are used in this technique
as mouth temperature waxes are too cumbersome to handle.
This technique is employed especially when the patient has
inflamed ridges and sore spots but can’t afford to keep dentures
out of mouth
9.
10. In the firm stage i.e, after 10-12 days, the denture with tissue
conditioner is treated as a Relined Impression
11. Once we have obtained a reline impression,
we pour & make a cast, preferably by beading
and boxing.
Next step is to replace the relining impression
material into denture base material.
12. Laboratory procedures replace the impression material from
the relined impression into new denture base material.
This can be done in 3 ways :
1. Flask Method
Here, conventional denture processing method is utilized where the
new denture base material can be a heat cured resin or cold cured
resin or Silicone resin liner
2. Articulator method
3. Jig method
In The above 2, the relined impression cast to be mounted over a
plaster base which serves as an index. The relining material is a
Self/Cold curing Acrylic (hard) or chemically cured Silicone ( soft or
hard)
19. Chair-side technique of relining
Here, a self curing silicone (usually soft) is
employed to serve as a denture base for
temporary periods (upto 6 months).
The silicone material binds to the denture base
quite efficiently .
Thus, no laboratory step is needed and relining is
accomplished in same appointment
The relining needs to be repeated after 6 months
or permanently relined with Cold –Cure material
afterwards.
