25
Does calculus cause periodontal infection
Not directly, but it allows attachment and retention of plaque biofilm.
26
Why do DH's remove calculus
So that the tooth surface is smooth, less likely for biofilm to attach and form.
27
How is calculus classified?
Either supra, or subgingivally Degree (slight, moderate, heavy) Extent (localized or generalized)
28
Where is supragingival calculus usually located?
Sublingual (under tongue) and adjacent to parotid salivary gland ducts. Resulting in calculus on mand anterior lingual surfaces and max posterior facial surfaces.
29
Other factors that influence calculus
Kidney dialysis, use of .12 chlorhexidine mouth wash, or genetic predisposition (increase in likelihood of getting something)
30
How is supragingival calculus detected
direct vision and compressed air.
31
Look of supragingival calculus
Yellowish- white but may take on stains and appear dark yellow/light brown.
32
Use of compressed air does what to the look of supragingival calculus
Make it appear to be chalky white.
33
Subgingival calculus is located..?
Below free gingival margin, often on root surface.
34
Subgingival calculus color
Dark green-brown-black color due to absorption of blood pigments.
35
How to detect subgingival calculus
Can be viewed by the use of compressed air deflecting gingival margin. Use of periodontal explorer. (sometimes by probing), feels like a ledge or ring around tooth. With trans-illumination calculus can be observed as dark. Sometimes visible on radiographs.
36
Calculus formation
It's formation follows the stages of biofilm formation. Calculus grows by the apposition of new layers of biofilm. Mineral source from saliva. About 10 (rapid calculus formers) to 20 days (slow calculus formers) are required for undisrupted oral biofilm to change to mineralized calculus.
37
Calculus composition
Inorganic 75-85% | Organic 15-25%
38
Materia alba | what is it?
loosely attached collection of oral debris.
39
Materia alba | what does it look like?
whitish to yellowish to greyish mass on teeth or overlying oral biofilm.
40
Food debris
composed of remnants of food.
41
How is materia alba and food debris removed?
Rinsing, use of an oral irrigator and self cleansing action of tongue and saliva.
42
A discoloured accretion or area on a tooth
Tooth stain
43
Stains that incorporate within the tooth structure
Intrinsic stains, cannot be removed via cleaning
44
Stains that occur on the outer surface of tooth
Extrinsic stains, removable by scalling, polishing, toothbrushing
45
3 general ways discolourations of teeth and restorations occur
1. Stain adheres directly to tooth surface. 2. Stain within calculus and/or soft deposits 3. Stain within tooth structure.
46
Significance of tooth stains
1. Appearance 2. Irritate gingival tissue, rougher surface for plaque and calculus adhesion. 3. Motivation to improve client's oral hygiene.
47
Exogenous (tooth stains)
Originate from sources outside, extrinsic (remains on tooth surface) - removable but may become intrinsic.
48
Endogenous (tooth stains)
Originate within, always intrinsic.
49
Common types of extrinsic stain:
Yellow Green Blackline Tobacco
50
Yellow extrinsic stain; | what is it, and occurrence
dull yellowish plaque; associated with poor oral hygiene. Origin - food pigment.
51
Green extrinsic stain | what is it
Light or yellowish to dark green, appears in plaque.
52
Green extrinsic stain | what shape is it
1. curved line along facial, gingival crest. 2. smeared irregularly on a smooth surface of tooth. 3. following developmental grooves on buccal of tooth.
53
Green extrinsic stain | significance
Enamel under stain is often decalcified***
54
Green extrinsic stain | location
labial, facial (may extend proximal. | usually labial cervical third of max anteriors.
55
Green extrinsic stain | composition
Chromogenic bacteria and fungi. Decomposition of hemoglobin. Inorganic elements.
56
Green extrinsic stain | occurrence
All ages, a sign of poor oral hygiene. | Usually children with enamel irregularities.
57
Black line stain | appearance
Continuous fine black/brown line. | 1mm wide.
58
Black line stain | location
Follows curves of gingival crest, 1mm away from edge. In pits and fissures Not usually on labial of max molars.
59
Black line stain | composition
Similar to plaque, difficult to remove with polishing, must be scaled off.
60
Black line stain | occurence
More common in children. Females In clean mouths, no plaque Natural tendency for some people to form it.
61
Tobacco stain | appearance
light brown - dark brown - black | leathery looking
62
Tobacco stain | occurance
cervical third on lingual surfaces, any surface; pits and fissures.
63
Tobacco stain | composition
tar from smoke; chewing tobacco, often accompanied by poor oral hygiene.
64
All extrinsic stain is exogenous or endogenous?
exogenous
65
Endogenous intrinsic stains. Pulpless Teeth: Appearance
Yellow-brown, grey, reddish brown bluish black.
66
Endogenous intrinsic stains. Pulpless Teeth: Cause
Caused by breakdown of the pulp or due to endodontic treatment.
67
Endogenous intrinsic stains. | Medications
Tetracycline - antibiotics absorbed by bones and teeth. Causes yellow to brown endogenous pigmentation of teeth. Can be passed on to fetus. Colour depends on type of tetracycline, dosage, duration. Generalized (specific teeth)
68
Intrinsic
In the tooth structure. Can occur during develipment of tooth. Can take place after eruption. Not sign of tooth weakness.
69
"hypo"
insufficient/lacking
70
Enamel hypoplasia
defect occurs as a result of a disturbance in formation of organic enamel matrix. Local or single tooth may exhibit the condition; due to trauma.
71
Hypomineralization
Insufficient mineralization during tooth formation. White spots on enamel Due to high fever at the time of development.
72
Pink tooth of Mummery
is a tooth exhibiting a pinkish hue as a result of hematologic staining of the dentin. Endogenous intrinsic stain.
73
Exogenous intrinsic stain | Restorative materials:
Amalgams - dental silcer amalgam - migration of metallic ions into tooth structure.
74
Exogenous intrinsic stain | Endodontics:
Mainly from older methods.
75
Exogenous intrinsic stain | Demineralization:
White to brown enamel. Acid erosion by plaque Minerals removed from enamel after tooth has erupted.
76
Exogenous intrinsic stain | Arrested caries:
Remineralized tooth structure following caries. Stain entered into the 'porous' demineralized area - then remineralized. Dark brown to black. On crowns, root surfaces.
77
Enamel fluorisis | Colour
Enamel fluorisis can be seen either mostly brown (A) or mostly white (B) discolorations.
78
Type I Embrasure
Papillae fills interproximal
79
Type II Embrasure
Slight to moderate recession (blunted papillae)
80
Types III Embrasure
Excessive or complete loss.
81
Indications for Bass/Sulcular technique
For open proximal areas (embrasures), beneath height of contour of enamel, exposed root surfaces.
82
Indications for Stillman's brushing technique
Gingival recession, for gingival stimulation, to clean from large embrasures, remove plaque and biofilm from cervical region.
83
Indications for Charter's brushing technique
Orthodontic and fixed prosthetic appliances, temporary cleaning of surgical site. Cleans interproximal areas.
84
Modified /bass, modified stillman's, and modified charter's
Adding a rolling stroke to all methods.
85
Modified /bass, modified stillman's, and modified charter's | Indications
Clean entire facial/buccal surfaces, avoids damage to bass of gingival sulcus.
86
Indication for Fones (circular) brushing technique
Indicated for children, sometimes for adults. | Simplest technique, but less effective.
87
Rolling stroke brushing technique indications
Used mostly in addition to bass, stillmanes and charters, we use this at the end of each technique.
