Ultrasonics in Endodontics

CONTENTS
INTRODUCTION
The use of ultrasonics or ultrasonic instrumentation was first introduced to
dentistry for cavity preparations using an abrasive slurry .Although the
technique received favorable reviews,it never became popular ,because it had to
compete with the much more effective and convenient high-speed handpiece.
However,a different application
was introduced in 1955, when Zinner reported on the use of an ultrasonic
instrument to remove deposits from the tooth surface. This was improved upon by Johnson and Wilson ,and
the ultrasonic scaler became an established tool in the removal of dental
calculus and plaque. The concept to using Ultrasonic in endodontics was first introduced
by Richman in 1957. However, it was not until
Martinetal ,demonstrated the ability of ultrasonically activated K-type files to
cut dentin that this application found common
use in the preparation of rootcanals before
filling and obturation. The term endosonics was coined by
Martin and Cunningham and was defined
as the ultrasonic and synergistic system of rootcanal instrumentation and disinfection.

Selection Of Cases for Endodontic Treatment

CONTENTS
INTRODUCTION
- In the past injured/diseased teeth were indicated for extraction
- Now the trend has been changed and the teeth can be saved by endodontic treatment because clinician and general population is becoming more aware of the importance of natural teeth
- Once a thorough examination has determined that an endodontic problem exists, the process of case selection begins.
- The dentist must determine
- whether treatment is indicated for this patient
- what treatment will best serve the patient
- whether the patient would be best served by being referred to a specialist or another practitioner.

INTRODUCTION
“ The lack of proper equipment “ is a reason often given by the dentist who do not practice RCT and it well might be not only are special instrument imperative for endodontic therapy. But a special arrangement of these instrument is necessary.
Impractical, inefficient scuring around the office to gather collection of unsterile ill-adapted equipment completely discourages the practitioner from endodontic therapy. These problems may be solved by procuring the correct equipment and supplies; by packaging the hand equipment into sterilized towel kits, into canisters, or on prearranged trays; and finally, by storing the small endodontic instruments in an organized, compartmentalized instrument case.
Endodontic armamentatium
Although most instruments used in general dentition also can be used for endodontic therapy. In addition, many many different types of instrument have been designed for procedures performed inside pulp space.
Preparation for treatment begins with selection of the armamentarium for routine endodontic patient care.
Instruments used for every patient should be assembled and sterilized before use.
list below gives typical armamentarium that can be customized for the individual practitioner

Root Intracanal Medicaments

For word file : http://www.mediafire.com/download/5p2fvn7sgzag799/INTRACANAL+MEDICAMENT.docx
CONTENTS
INTRA CANAL
MEDICATIONS
Medicaments are effective
antimicrobial agents.With the number of microorganisms reduced by irrigation
and instrumentation ,the medicament destroys those remaining and limits the
growth of any new arrivals
Ideal
requirements
According to the Grossman
1.
It
should be effective antimicrobial agent
2.
Should
be nonirritating to the periradicular tissues
3.
Should
be stable in solution
4.
Should
have a prolonged antimicrobial effect
5.
Should
be active in the presence of blood, serum and protein derivatives of tissues
6.
It
should not stain tooth structure
7.
It
should not induce a cell mediated immune response
Root Canal Irrigations
FOR word file: http://www.mediafire.com/download/fbyeekzb3od7i6s/IRRIGATION.docx
CONTENTS
IRRIGATION
Irrigation serves as a physical flush to remove debris as well as serving as a antibacterial agent ,tissue solvent and lubricant.Some are effective in removal of the smear layer .It is highly recommended that canal always be instrumented while containing an irrigant or lubricating agent
Requirements of a ideal irrigant
1. Should be good tissue or debris solvent
2. Should have low toxicity
3. Should have low surface tension to promote flow into inaccessible areas
4. Should be biocompatible
5. Should be a lubricant
6. Should have antimicrobial properties
7. Should be capable of removing the smear layer

CONTENTS
INTRODUCTION
The concept of single visit
endodontics started at least 100 years back . Initiating and completing an
endodontic treatment in one appointment
has always been surrounded by
controversy
The majority of endodontists thought
that performing treatment in this manner would
cause more postoperative pain
than if performed in multiple appointment
DEFINITION
Single visit endodontics implies to
cleaning , shaping and disinfection of a root canal system followed by
obturation of the root canal at the same appointment
FACTORS FOR NOT PERFORMING SVE
- Doubt of post operative pain
- Fear of failure of the endodontic therapy
- Discomfort to patient because he or she has to keep the mouth open for
a long period of time
- Lack of time
- Lack of experience and equipment
