Periodontology 6th E
Ch 19 Clinical Periodontal Assessment
| Question | Answer |
|---|---|
| If the periodontal chart indicates that all the probing depths are between 1 and 3 mm but does not indicate the position of the gingival margin or any CAL readings, can the dental hygienist assume that this patient has a healthy periodontium? | No, because the chart provides no way to tell if the patient has attachment loss |
| What are the components of a comprehensive periodontal assessment? | Level of mucogingival junction, level of free gingival margin, CAL, mobility, furcations, fremitus, gingival conditions, probe depths, bleeding on probing |
| What class of mobility would a patient have if a molar has an 8-mm attachment loss and the hygienist is able to depress the tooth in its socket by applying downward pressure? | Class 3 |
| What class of mobility would a patient have if a molar has greater than 1mm of horizontal displacement in a facial-lingual direction? | Class 2 |
| What class of mobility would a patient have if a molar has 1 mm attachment loss and the hygienist is able to move it slightly in a facial-lingual direction? | Class 1 |
| If the hygienist applies pressure with a gloved finger against the facial gingival tissue of a tooth and observes a pale yellow material oozing from the orifice of the pocket, what is the substance? | Exudate |
| If the dental hygienist inserts a Nabers furcation probe into the pocket and tries to move the tip between the mesial and distal roots of the tooth, what is he or she assessing for? | Furcation involvement |
| If moderate alternating pressure in a facial--lingual direction is applied against the tooth, first against the facial surface of the tooth, then from the lingual surface of the tooth, what is the hygienist assessing the tooth for? | Horizontal tooth mobility |
| If moderate pressure against the occlusal surface is applied in an upward direction, what is the hygienist assessing the tooth for? | Vertical tooth mobility |
| What does bleeding on gentle probing represent? | Bleeding from the soft tissue wall of the periodontal pocket where the wall of the pocket is ulcerated due to disease |
| How should a hygienist assess for bleeding? | Observe each site for a few seconds before moving on to the next site |
| What measurement is being obtained when the hygienist uses a probe to measure the distance from the CEJ to the base of a pocket? | Clinical attachment level |
| In what conditions can inflammation not always be clinically visible in the tissues? | Both gingivitis and periodontitis |
| What condition is being assessed for if the hygienist places his gloved index finger against the facial surface of the crown and asks the patient to tap her teeth together? | Fremitus |
| What is it called if the dental hygienist performs an efficient periodontal screening to determine IF she needs to complete a comprehensive periodontal assessment on a patient? | Periodontal screening and recording (PSR) |
| What is it called if the hygienist begins a new patient to the practice with a fact-gathering process designed to provide the hygienist with a comprehensive picture of the patient's periodontal health status? | Comprehensive periodontal assessment |
| If the furcation probe passes completely through the furcation between the mesial and distal roots but the entrance to the furca is not visible clinically, what is the level of furcation involvement? | III |
| If the furcation probe passes completely through the furcation between the mesial and distal roots and the entrance to the furca is visible clinically, what is the level of furcation involvement? | IV |
| If the furcation probe does not pass completely through the furcation but it penetrates greater than 1 mm, what is the level of furcation involvement? | II |
| If the tip of the 11/12 explorer can detect the curvature of the furcation but cannot enter inside the furcation, what is the level of furcation involvement? | I |
| What is the importance of assessing calculus deposits on teeth during a comprehensive periodontal assessment? | Calculus deposits must be removed during nonsurgical therapy, and calculus is a local contributing factor in disease |
| What is the biggest difference between periodontal screening and recording (PSR) and a comprehensive periodontal charting? | PSR records one code for each sextant, and comprehensive periodontal charting records six readings for each tooth |
| Why is thorough documentation of periodontal assessment findings in the patient chart or computerized record important? | To serve as baseline data, to measure treatment outcomes, and to monitor periodontal health over time |
| When assessing for furcation involvement on a maxillary first molar, what could be a reason that the probe penetrated into the furcation but did not go through to the lingual? | The lingual root stopped the probe |
| What is the proper way to calculate the width of the attached gingiva? | Subtract the probing depth from the total width of gingiva |
| During a periodontal assessment on a patient, the hygienist uses a probe to measure the distance from the CEJ to the base of a pocket. What is the hygienist trying to determine? | Clinical attachment level |
| What is the clinical attachment loss for the facial surface of the tooth if there is a gingival margin level of +3mm and a probing depth measurement of 6 mm? | 9mm |
| What is the clinical attachment loss for the facial surface of the tooth if there is a gingival margin level of -3mm and a probing depth measurement of 5 mm? | 2 mm |
| What is the width of the attached gingiva for the tooth if the total width of the attached gingiva is 6 mm and the probing depth is 7 mm | -1mm |
