The goal of root canal therapy is to restore the health of your damaged tooth. During treatment, the pulp is removed from your root canals through a small opening in the crown. Then the canals are cleaned and disinfected

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

2. Objectives of root canal preparation
The root canal system must be:
• Cleaned of its organic remnants
• Shaped to receive a three
dimensional filling of the entire
root canal space
3. Objectives of root canal preparation
The canal is
• Cleansed primarily by irrigation
• Shaped primarily by instrumentation
4. Five Mechanical objectives
•Develop a continuously
tapering conical form in the
root canal preparation
•Make the canal narrower
apically, with the narrowest
cross-sectional diameter at
its terminus
•Make the preparation in
multiple planes
•Never transport the
foramen.
•Keep the apical foramen as
small as possible Herbert Schilder
The real key to
obturation is
Cleaning and Shaping
5. Cleansing of the root canal
Objectives
• Removal of organic and
inorganic debris
• Elimination of bacteria
16. METHODS OF DETERMINING
WORKING LENGTH
• Radiographic Methods
• Digital Tactile Sense
• Apical Periodontal Sensitivity
• Paper Point Measurement
• Electronics
20. Clinical Procedure
Actual WL determination
Preparation should terminate at
• Apical constriction
• 1 mm short of radiographic apex
21. Clinical Procedure
• Estimate working length
• Parallel radiograph
• Estimated working length is the distance from
the reference point to the radiographic apex
27. Master Apical File
• Take a radiograph with MAF in place.
This confirms:
– Length
– Placement
28. RECAPITULATION
Repeated reintroduction and reapplication
of instruments previously used
throughout the cleaning and shaping
process in order to create well-designed,
smooth, unclogged, evenly tapered root
canal preparations.
29. Apical Patency
Maintain a pathway
through the apical constriction
with a small K-file (#10 or #15)
during cleaning and shaping
31. Crown Down Technique
•Coronal third Orifice shapers
•Middle third 0.06 taper rotary Profiles
•Apical third 0.04 taper hand Profiles
32. Crown Down Technique
• The coronal portion is prepared before the apical
portion
• Reduces effect of canal curvature
• Improves tactile awareness during apical
preparation
• Allows more effective irrigation
• Removes majority of tissue and microbes before
apical third is approached
• Reduces change in working length during apical
preparation
35. • Sodium Hypochlorite:
• Lower concentrations (e.g., 0.5% or1%) dissolve mainly necrotic
tissue
• Chlorhexidine:
• A broad-spectrum antimicrobial agent effective against gram-
negative and gram-positive bacteria
• A cationic molecular
• binds to hydroxyapatite
Iodine Potassium Iodide:
• an oxidizing agent by reacting with free sulfhydryl groups of
bacterial enzymes
• MTAD
• EDTA
• Hydrogen peroxide
36. Cleaning---Irrigation
• Sodium Hypochlorite?
• Dissolves organic debris ✔
• Has a powerful anti-bacterial action ✔
• Lubricates the use of files ✔
• Disinfects & cleans where files don’t reach ✔
• The tissue-dissolving ability of 5.25-1%
What irrigant should we use?
