Chapter 19 & 21
List some effects of Tobacco smoking on the periodontium.
Reduces bleeding to decreased vascularization of periodontium
Less inflammation of periodontium
Changes in pocket involvement resulting in different bacterial pathogens
What procedures fall under non-surgical periodontal therapy?
Periodontal instrumentation, oral health education and use of chemical agents
Which of the following is the most frequently used aid for biofilm removal?
Toothbrush
Difference between patient-applied home irrigation and professional irrigation.
Patient-applied home irrigation is to diminish gingival inflammation by disrupting biofilms coronal to the gingival margin
Professional irrigation is to reduce the number of bacteria in the periodontal pocket space
Clinical data collected at the periodontal maintenance appointment should be measured against what?
Baseline Data
During a periodontal assessment, the hygienist notes no bleeding on probing. In a smoker does this finding always indicate a healthy periodontium?
No, because clinical signs of inflammation are suppressed
The measures for non-surgical therapy are carried out by which professionals/individuals?
Which of the following interdental cleaning devices is effective in a type I embrasure space?
Floss
Describe impact and flushing zones.
Impact zone---initial fluid contact near the gingival margin
Flushing zone---depth of fluid penetration within a subgingival sulcus or periodontal pocket
Goals of Periodontal Maintenance
To minimize the recurrence and progression of periodontal disease
To reduce the incidence of tooth loss
Increase the probability of detecting and treating other oral conditions
The expected outcome of achieving these goals is to maintain the dentition throughout the life of the patient
List some systemic contributing factors that could lead to periodontal disease
Stress, Hormones, Diabetes
what term is used to define the act of “removing rough cementum or dentin that is impregnated with calculus or toxins?”
Root planning
Describe Type I, II, and III embrasure spaces.
Type I: interdental papilla is present and fills interdental space.
Type II: Interdental papilla reduced
Type III: Interdental papilla is missing
The ability of a chemical plaque control agent to be retained in the oral cavity and be released slowly over time with a continued antimicrobial effect
Substantivity
A patient can sue a dentist and a hygienist, but the success of the law suit depends on
Quality of Chart Notes
List structures that are radio-opaque in a radiograph
Enamel, Lamina Dura, Amalgam
What interdental aid is best used on root concavities?
Interdental brush
For a chemical agents to be effective, 3 criteria must be met, what are they?
1.Reach the site of disease activity (base of pocket)
2.Ability to be delivered at a bacteriostatic or bactericidal concentration
3.Remain in place long enough to be effective
What do we mean by liability?
Liability is a health care provider’s obligation to provide services to another person.
Can radiographs reveal periodontal disease activity?
No, best is clinical periodontal assessment.
What is the primary pattern of healing after periodontal instrumentation?
Formation of the long junctional epithelium
Tufted Dental Floss is great to clean what areas of the oral cavity.
Great for cleaning under pontics of fixed bridges or distal of last tooth in arch. Also good in open interdental spaces
What are some control release mechanism, that are used in private practice?
Arestin, Atridoc, and Perio Chip
Name some areas of potential liability for a dental hygienist
1.Failure to ask and document whether a patient has taken his or her medication
2.Failure to detect and document oral cancer
3.Failure to update a patient’s medical history
4.Failure to detect and thoroughly document the presence of periodontal disease
5.Injuring a patient
6.Failure to thoroughly document treatment in the patient chart or computerized record
7.Failure to protect patient privacy or divulging confidential patient information
8.Failure to inform the patient about treatment options and the consequences of no treatment
9.Practicing outside the legal scope of practice. Know your state’s rules and regulations!
10.Failure to provide care that meets the established standards of care
