The first visit to the dentist, the dentist will gives you local anaesthesia and remove all the pulp tissue. He will then put a temporary filling material to fill up the empty spaces. This process is called Access Opening. During the second visit, the temporary filling material is removed and root canal material like gutta percha is placed. A temporary filling material is placed again. This process is called Obturation. During your last visit, the temoporary filling material is removed and replaced by permanent filling material like composite/amalgam and a crown preparation is done.
Apexification is a method to induce development of the root apex of an immature, pulp less tooth by formation of osteocementum or other bone-like tissue. It differs from apexogenesis, the physiologic process of root development.
Clinical endodontics has changed and expanded over the years due to improvement in cleaning and shaping procedure,culturing, intra canal medicaments and root canal filling materials and techniques
Chemical preparation refers to use of an irrigant or combination during and after biomechanical preparation of root canal.
Earlier in 1940 water was commonly used irrigant since it was readily available ,inexpensive and provided a lubricating effect like all non viscous fluids.
Complete cleaning and shaping and thorough irrigation is essential before disinfecting the canal.
Disinfection of root canal (destruction of pathogenic M.O) is accomplished by intra canal medication
The base of the flap should be wider than incisal margins for adequate blood flow to the reflected flap.
The flap should be designed with continuous curvatures between horizontal and vertical incision to avoid sharp angles
Preservation of the dentition and maintenance of function are dental professions ultimate goal.
The advances in non surgical endodontic therapy has been explosive, but it has also been a mixed blessing.
It has led to procedural errors such as, broken instrument ,ledges etc
It is indicated in fewer than 5% of endodontically treated teeth. The success rate of endodontic surgery is high, ranging from 73-99%.
ACUTE PERIODONTAL ABSCESS
Pain and swelling
It is usually mistaken for acute alveolar abscess
It may occur with vital or necrosed pulp, but its origin is
usually an exacerbation of infection with pus formation
in an existing deep infra bony pocket.
What is Endodontic Emergency?
Defined as an unscheduled visit associated with pain or swelling from pulpoperiapical pathoses requiring immediate diagnosis and treatment.
Chronic Hyperplastic Pulpitis:
Definition: Chronic hyperplastic pulpitis or”pulp polyp” is a productive pulpal inflammation due to an extensive carious exposure of a young pulp.
This disorder is characterized by the development of granulation tissue, covered at times with epithelium and resulting from long-standing, low – grade irritation.
