charting
uk/ zsigmondy-palmer charting:
- divided into 4 quadrants (ur, ul, lr, ll)
- permanent teeth 1-8
- deciduous teeth A-E

blacks clasifications
- class 1- single surface
- class 2- proximal surfaces
- class 3- cavity on mesial or distal on incisor or canine
- class 4- like class 3 but including incisal edge
- class 5- on cervical margin
BPE Scores
code 0- healthy gums, no bleeding, no treatment required
code 1- mild gingivitis, bleeding on probing, will need ohi advice, use floss and toothbrush. suffering from mild gingivitis
code 2- presence of calulus or defective restoration, will need scale and polish or removal or replacement of defective restoration. suffering from marginal gingivitis
code 3- pockets less than 5.5, will need root surface debridment (RSD) and a six pocket chart, suffering from periodontitis
code 4- pockets are more than 5.5, will need full mouth 6 point pocket chart, subgingival debridment, they are suffering from periodontitis
*- gingival recession of furcation involvment present
external checks
skin- skin colour, facial symmetry and blemishes, this would include moles as could be a sign of skin cancer
lips- colour change, abnormalities like lumps, blemishes or cold sores
lymth nodes- under mandible and in neck, for swelling, lumps could be a sign of infection
temporomandibular joint (TMJ)- clicking, pain and discomfort
internal checks
labial, buccal, and sulcas muscosa- colour, texture and moisture levels
palatal mucosa- hard and soft tissues and tonsils
tongue- colour, texture, symmetry, movement, and level of movement
floor of mouth- colour texture and swelling
methods of assessments
vitality
study models
photographs
visial inspection
manual inspection
mouth mirrors
dental probes
transillumination
periodontal probe
radiographs
probes
right angled probe- is used to find caries, decay and calculus, as wella s overhanging restorations.
periodontal probe (CPITN OR WHO)- used for bpe score
brault probe- used for iterproximal areas
sickle probe- interproximal areas, feeling for caries and tissues
transillumination and vitality
trasilllumination- a light that shines on a tooth and shwis frcatures, caries and fissures
non-vital tooth- dead tooth
vital tooth- a alive tooth vitality tests: cold test, hot test and an electric test.
a person with a dead tooth will not feel anything, if reacts highly they have pulptitis and if they react slightly tooth is vital, if the patient reacts near the end then the tooth is dying and root canal would be done.
cold test uses endofrost or ethyl chloride
electric test is more accurate, it uses tooth paste and a mild electric current, you cnat use it on someone who has a pace maker
hot test uses gutapercha or green stick and is harder to do
mobility recording
grade1- side to side movement less than 2mm
grade 2- side to side movement more than 2mm
grade 3- vertical movement as well
full perio assessment
it involves:
six individual pocket depths recorded around each tooth
gingival bleeding recorded for each tooth
plaque scores
mobility recorded
vitality recorded
study models
x-rays
photographs
ortho measurements
used for patients being referred for ortho treatment
records taken: classification of occlusion, overjet and overbite measurement, presence and location of crowding in each dental arch, presence of retained deciduous teeth, tooth rotations, spacing and unerupted teeth
IOTN score iedntify if pateint are eligible for treatment on NHS
x-ray periapicals
3cm-4cm
unerupted teeth and retained roots
prior to a difficult extraction
chronic alveolar abscesses
root treatment
periodontal disease
orthodontics
bitewings
3cm- 4cm
film against lingual surface of teeth
shows crowns and interdental spaces of molars and pre molars
prosteria teeth in occlusion
horizontal bitewing- view interproximal areasof prosteria teeth, occlusal and recurrent caries, restoration overhang
vertical bitewing- view periodontal bone levels of posteria teeth and presence of true periodontal pockets
occlusals
plane view of mandible and maxilla
unerrupted teeth
lateral oblique
13cm- 18cm
half view of OPG but depends on technique used
assessment + presence of unerupted teeth
fractures of mandible
evaluation of lesions such as cysts, tumours
views of salivary glands or TMJ
alternative to intra oral views due to gagging or other difficulties
panoramic radiography (OPG)
13-31cm
unerupted teeth
cysts
fractures
bone disease
orthodontics
also known as dental pantomograph or orthopantomograph (OPG)
cephalometric radiography
cassette 18cm- 24 cm
side and front views taken with cephalostat
orthodontic diagnosis
oral surery such as surgical alteration of jaw relationship
location of the position and angulatation of unerupted upper caines
it is also known as skull x-ray
x-rays
basic methods of producing x-rays
directly onto a film
using x-ray to create a light pattern, which exposes the film
using digital image receptors
intensifying screens + x-ray films
intensifying screens
plates containing phosphers which glow when struck by x-rays
light produces latent image in film
reduces x-ray dose needed
x-ray films consist of:
film in middle- green with pimple
black paper or card
plastic light tight wrapping
techniques
paralleling- held parallel to long axis of tooth being exposed
bisecting angle- film placed intra-orally and angulation of long axis of tooth against film determined by operator
paralleling requires beam aiming devices and film holders
teeth
types of teeth- incisors and lateral incisors, first and second premolars , first second and third molars
function of teeth:
cut up and chew food
support oral, tissues and clear speech
expose food surfaces to enzymes and allow digestion
