|
What is the best indicator that a patient is at risk for caries? |
Prior caries |
|
|
What are the six steps to caries prevention, in order of importance? |
1) Fluoride 2) Sealants 3) Nutrition 4) Oral hygiene with fluoride toothpaste 5) Regular dental visits 6) ID white spots, deliver Fl |
|
|
What's the official terminologies for "finding a lesion" and "deciding if found lesion is active (if so, how active) or arrested" |
Detecting caries, diagnosing caries |
|
|
When it comes to caries detection, what is the practitioner's emphasis (or at least, what should it be) |
Early detection of non-cavitated lesions |
|
|
How does the traditional visual-tactile caries exam rate in regards to sensitivity and specificity? |
Low-moderate sensitivity (has a decent chance of missing carious lesions) High specificity- very few false positives |
|
|
What explorer is used in traditional tactile caries detection? |
The #23 (Cowhorn) explorer |
|
|
What is the job of all the fingers in the modified pen grasp used to hold explorers? |
Thumb and index: grasp instrument Middle: Guides the instrument (rests on shank) Ring: rests on adjacent tooth Little finger: Has no function, is kept down |
|
|
What finger acts as the fulcrum? Where should it be kept ideally? |
The ring finger; it should be kept on an occlusal surface of a tooth in the same arch, as close to working area as possible |
|
|
What are two ways to get rid of fog on the dental mirror? |
- Hold in cheek to warm - Rinse in mouthwash |
|
|
What's the term and treatment for beginning caries? |
Incipient caries- treat with fluoride and keep an eye on 'em |
|
|
When should the explorer be used to probe an area for caries? How should this be done? |
If a region is suspicious but not obviously carious, the explorer should be gently dragged upon the surface in question to look for a sticky/tacky feeling. Vertical probing for a "tug back" is a no |
|
|
What are four important factors to consider in classifying a lesion? |
- Does pt have caries in other areas? - Does pt visit dentist regularly? - Does pt demonstrate good oral hygiene? - Ease of restoration? |
|
|
What tool is used to check the margins of crowns? |
Pigtail explorer |
|
|
When checking crown margins, if your explorer catches and you get a "ting" (no idea what this means), then it's indicative of what? |
Restoration is defective, and likely has open margins |
|
|
5 Pro-explorer arguments: |
- Explorer use is cheap, easy - Explorer use is time-efficient - Explorer's excellent sensitivity is proven - Studies against explorer use are weak - DMFT (decayed, missing, filled teeth) rate in US is decreasing– if explorers are bad, how come this? |
|
|
5 Anti-explorer arguments: |
- White spot lesions can remineralize - Explorer can damage surface of teeth - Explorer results variable - Today's clinical caries exam should include ID of precavitated lesions - Primary use is removal of plaque from exam area and determining roughness of white spots (I don't get how this is a con) |
|
|
What type of caries are not found well on x-rays? What type of caries are x-rays perfect for? |
X-rays are bad for occlusal caries detection, and great for interproximal detection |
|
|
What is the downside to caries detection dyes? |
They overstain, resulting in over-restoration |
|
|
In an Angle's Class 1, what cusp rests in what groove? |
Mesiobuccal cusp of max. 1st molar rests in buccal groove of mandibular first molar. |
|
|
What Angle's class corresponds to overbite? Where does the maxillary mesiobuccal cusp rest in this situation? |
Angle's Class 2; Max. MB cusp is mesial to buccal groove of mand. 1st molar. |
|
|
What Angle's class occurs when max. 1st M. mesiobuccal cusp sits distal to the mandibular 1st M. buccal groove? What's the "layman's term" for this condition? |
Angle's Class 3; underbite |
|
|
What's the difference between overbite and overjet? |
Overbite is in the vertical direction; it refers to when a tooth's incisal edge extends much further than the incisal edge it's in front of.
Overjet is in the horizontal direction; it refers to when the angle between an outside tooth and inside tooth is too large. |
|
|
What's crossbite? |
Crossbite is when maxillary teeth are posterior to mandibular teeth. |
|
|
What does the term "maximum intercuspation" refer to? |
Fully biting down |
|
|
What are three signs of occlusal trauma? |
- Wear facets - Broken restorations - Chipped teeth |
|
|
"rubbing, gritting, or grinding together ofthe teeth, usually during sleep" is known as: |
Bruxism |
|
|
What is abfraction? |
Loss of the cervical area of teeth, resulting in a little "ledge" where the crown normally would meet gingiva; common indicator of bruxism |
|
|
What are 5 symptoms of bruxism? |
- TMJ problems - Headache - Sore muscles - Cheek irritation - Scalloped tongue |
|
|
When teeth are ground down, we refer to the wear using this term: |
Attrition |
|
|
Wear which results from: -Bad brushing technique -Toothpicks -Chewing nails -Brushing teeth Is called: |
Abrasion |
|
|
What's the name for wear that's occurred to teeth as a result of abnormal chemical exposure? |
Erosion |
|
|
When erosion is especially present on the lingual surface of teeth, what is that often an indicator of? |
Bulimia |
|
|
Raised amalgams, thermal sensitivity, thinning and chipping of incisal edges, and enlarged salivary glands are all symptoms of this: |
Bulimia |
