“Organized Dentistry” 
“Management of Periapical Pathosis”

Chad Gehani, D.D.S. –
Associate Clinical Professor – NYU, Chairman - Department of Endodontics – Flushing Hospital, Fellow – American College of Dentists, Past President – New York State Dental Association.

Respected clinician; visionary leader; passionate educator; admired mentor; humanitarian, and effective collaborator making significant contributions to organized dentistry, oral health care and dental education.


A brief overview of organized dentistry will be followed by a short Q&A session prior to Dr. Gehani’s presentation of his Endodontics program “Management of Periapical Pathosis”.

“Organized Dentistry”

Organized dentistry encompasses the efforts of ADA members, staff and supporters at the local, state and national levels, known as the tripartite, that all work to positively contribute to the dental profession and to uphold three primary principles:  Advocacy, Education and Service

“Management of Periapical Pathosis”
The purpose of this presentation is to limit scope of treatment of the Endodontically involved pulp and extended periapical lesion – a non-surgical approach.  More than 90 percent of all Endodontic problems can be treated by this one therapy.  For a predictable and reproducible success in Endodontic therapy, a careful and complete diagnosis must be made on each and every suspected tooth.  Learn to avoid errors in pathological lesions that might be mistaken for an endodontic lesion:

  • Median Maxillary Cyst
  • Globulomaxillary Cyst
  • Hemorrhagic Traumatic Bone Cyst
  • Lateral Periodontal Cyst
  • Neoplasm
  • Cementoma
“Orthodontics : An Integral Part of Cosmetic Dentistry”
Rekha Gehani, D.D.S. – Diplomate American Board of Orthodontics

This presentation will include:

  1. Goals and objectives of orthodontic treatment.
  2. The three Golden Rules for success in orthodontic treatment:  Diagnosis! Diagnosis! and Diagnosis!!
  3. Proper integration of different specialties in achieving the best results for your patients.
  4. Mutilated dentition: What is the best approach in resolving this problem?
  5. What is the future of this specialty?
