Preventive Lec 10 - Dental Needs and Dental Demand

The sources provided discuss the organization of dental care, the roles of various dental personnel, and the concepts of dental needs and demands. Below is a comprehensive translation and summary of the key concepts into English:
1. Organization of the Dental Team
The dental workforce is categorized into several roles based on their qualifications and duties:
• The Dentist: A graduate of a dental college who holds a license to practice. They supervise assistants and are qualified to perform dental procedures
.
• The Intern: A graduate who has completed five years of study and is undergoing one year of supervised training before receiving a professional license
.
• The Specialist: A dentist who has obtained a postgraduate degree (Master’s or Diploma) in a specific field, such as an Orthodontist or a Pedodontist
.
• Dental Auxiliaries: Personnel who do not have a dental degree but receive specific training to assist in the clinic
,. They increase work efficiency, improve team satisfaction, and reduce the time and stress required for procedures
.
2. Types of Dental Auxiliaries
The sources divide auxiliaries into three main categories:
A. Non-Operating Auxiliaries These individuals are not permitted to perform procedures within the oral cavity
,
.
• Clinical/Receptionist: Handles patient reception, sterilization, instrument preparation, and filing
.
• Chairside Assistant: Works directly next to the dentist. This role birthed the term "Four-handed dentistry," where four hands (the dentist’s and the assistant's) work in the oral cavity simultaneously
. They help reduce mental and physical stress on the dentist and increase the number of patients seen
.
• Laboratory Technician: Works in a lab to create dentures or appliances. While they generally cannot work on patients, the sources note that this is only legal in Denmark and Australia; in Egypt and most other countries, it is illegal for technicians to work directly in a patient's mouth
.
B. Operating Auxiliaries These individuals are permitted to perform specific tasks within the oral cavity
.
• Dental Assistant: Can be trained to perform limited tasks such as placing rubber dams, temporary fillings, or matrix bands
• School Dental Nurse: A role that originated in New Zealand to address dentist shortages
. They provide preventive care (scaling, education, fluoride) and limited treatment (primary teeth extractions, cavity preparations) for students,
• Dental Hygienist: Primarily focused on preventive care
. They work in both community settings (school screenings and education) and private clinics (scaling, polishing, and X-rays),
C. New Types for Underdeveloped Areas (WHO) The World Health Organization (WHO) suggested two roles for regions with a shortage of dentists or facilities:
• Dental Licentiate: A semi-independent operator with two years of training who can perform scaling, fillings, and extractions under local anesthesia
• Dental Aide: Provides "first aid" for dental health, focusing on emergency pain relief
3. Teamwork vs. Group Practice
• Teamwork: A group of specialists working together with a unified treatment goal for a single patient, such as a "Cleft Lip and Palate" team
. It includes professionals and sometimes non-professionals, and must consider the patient's opinion
• Group Practice: Multiple dentists working under one roof (like a polyclinic). It usually consists of 6 to 12 individuals, including general practitioners and specialists
◦ Advantages: Better care through consultation, ease of referral, and centralized patient records
. It also benefits dentists by allowing for shared equipment costs and professional discussion
◦ Disadvantages: Potential for personality conflicts and the patient feeling "shuffled" between different doctors
4. Dental Needs and Demands
The sources distinguish between what a population "needs" and what it "demands":
• Dental Needs: Health conditions diagnosed by a professional practitioner
◦ Normative Need: What the doctor defines as necessary after an exam
◦ Felt Need: The patient's subjective feeling of need (which may be inaccurate if the condition is asymptomatic)
• Dental Demand: When a patient feels a need and takes action by seeking treatment
Factors Influencing Needs and Demand:
• Age: Different age groups have different needs (e.g., 12–14-year-olds need trauma care; those in their 40s often need periodontal care)
• Gender: Males often seek quick solutions like extractions, while females may prioritize aesthetics (cosmetics) and oral health maintenance
• Socio-economics: High-income areas often have lower unmet needs due to better education and frequent dental visits
5. Dental Manpower
This refers to the workforce available to provide dental care
• The Supply Ratio: The WHO suggests a ratio of 1 dentist per 2,000 people for adequate service
• The Egyptian Context: In 2005, the ratio in Egypt was approximately 1:3,000, which was considered low by international standards
