	Describe etiologic factors of periodontal disease and their significance.
	Describe various forms of periodontal disease including histopathology.
	Discuss the relationship between systemic health factors and the progression of periodontal disease, including immunological complex.
Epidemiology of Periodontal Diseases		3	0	0
	Define and understand the prevalence data and risk factors associated with periodontal diseases.
Periodontal Diseases		8	0	0
	Dental plaque-induced gingival diseases and non-plaque induced gingival diseases.
	Chronic and aggressive periodontitis as a manifestation of systemic diseases.
	Necrotizing periodontal diseases.
	Abscesses of the periodontium.
	Periodontitis associated with endodontic lesions.
	Developmental or acquired deformities and conditions around the teeth.
Disease Prevention and Treatment Planning		5	0	0
	Describe various plaque control and desensitization techniques.
	Discuss the theories and strategies for motivating patients to take an active role in their own oral health care.
	Understand the individual patient’s needs for treatment planning and develop a treatment plan utilizing all available assessment data.
	Understand the need to reevaluate the dental hygiene plan of care to assess the tissue response and determine an appropriate STP interval, and evaluate the need for referral to a periodontist.
Non-surgical Periodontal Disease Therapy		5	0	0
	Describe principles of scaling, root planing, periodontal debridement, and soft tissue curettage. Discuss specialized instrumentation techniques and armamentarium for furcation involvement, and deep periodontal pocket therapy.
	Describe the healing process and the desired short and long term goals non-surgical periodontal therapy.
	Discuss rationale for surgical therapy and post surgical care.
	Describe surgical and non-surgical periodontal therapy methods utilizing the AAP decision continuum for treatment.
	Understand the need for some aggressive periodontal treatment plans to include medical supervision due to systemic conditions.
	Discuss the relationship of tobacco use and the severity of periodontal diseases with the patient.
	Understand the role traumatic occlusion plays in the severity of periodontal diseases.
	Discuss the plaque retentive factors, such as restoration contour, overhangs, orthodontic bands and faulty restorations and how removing these iatrogenic irritations can aid in the periodontal healing process.
Drug Therapy		2	0	0
	Discuss current drug therapy related to periodontal disease including antimicrobial agents and methods of delivery.
	Understand the systemic antibiotics that are used in the treatment of more aggressive forms of periodontal diseases.
Immunology and Host Defense Mechanism		3	0	0
	Understand the orderly sequence of events that occurs in response to any injury or infection.
	Understand the importance of PMN function in the maintenance of periodontal health but how they may also be responsible for periodontal destruction.
	Understand the cellular elements and immunoglobulins involved in immune response in periodontal diseases.
Microorganisms Associated with Periodontology		2	0	0
	Understand the microbial flora found in the gingival crevice in health and disease.
	Discuss the pathogenicity and the part it plays in tissue destruction.
The Principles of Periodontal Surgery		4	0	0
	Describe the conditions present in the periodontium that may require surgical treatment.
	Understand the potential therapy procedures and know when surgical intervention may be needed.
	Describe the advantages and disadvantages of periodontal surgical procedures with an understanding of the goals for the procedures.

	Discuss the implications of gingival, periodontal and pericoronal abscesses in the periodontal disease process.
Implantology and Maintenance of Implants		3	0	0
	Understand the patient selection, and considerations for implant usage and the implant materials.
	Understand the clinical measures, evaluation of tissue; therapist instrumentation, and patient home care implications in implant care.
