4 muscles of mastication are
lateral pterygoid, medial pterygoid, masseter and temporal muscle
lateral pterygoid
pulls the jaw forward. one alone swings the jaw side to side
medial pterygoid
behind maxilla, closes the mandible
masseter
from the cheekbone, for side to side and closing
temporal muscle
relating to TMJ, closes mandible and pulls jaw backwards
TMJ
temporamandibular joint

obicularis oris
ring of muscle around mouth
buccinator
cheek muscle, controls food and talking
serous saliva
watery and protein fluids
mucous saliva
thick and consists of carbs
parotid salivary gland
situated in front of each ear
1000ppm toothpaste is recommened for
all patients
1500ppm toothpaste is recommended for
adults at high risk of developing caries

the three groups of muscles around the face and jaws
suprahyoid muscles, muscles of mastication and muscles of facial expression
the muscles of mastication are arranged as four pairs, these are:
temporalis, masseter, lateral pterygoid and medial pterygoid
trismus
limited mouth opening
limited jaw opening
trismus
nerve supplying the teeth and soft tissues of the oral cavity
trigeminal nerve
the five nerves in the maxillary division
anterior superior dental nerve, middle superior dental nerve, posterior superior dental nerve, greater palatine nerve and nasopalatine nerve
the four nerves in the mandibular division
inferior dental nerve, lingual nerve, long buccal nerve and motor branch to muscles of mastication
nerve which supplies incisor and canine teeth and their labial gingivae
anterior superior dental nerve
nerve which supplies premolars and mesial half of first molars and their buccal gingivae
middle superior dental nerve
nerve which supplies distal half of first molar and second and third mmolar teeth and their buccal gingivae
posterior superior dental nerve
nerve which supplies palatal gingivae of molars, premolars and half of canine teeth
greater palatine nerve
nerve which supplies palatal gingivae of incisors and half of canine teeth
nasopalatine nerve
nerve which supplies all of lower teeth, the labial/buccal gingivae of premolars and forward and the soft tissues of the lower lip and chin
inferior dental nerve
nerve which supplies the lingual gingivae of lower teeth, floor of the mouth, and all but taste sensation from the anterior two-thirds of the tongue
lingual nerve
nerve which supplies the buccal gingivae of the molar teeth
long buccal nerve
nerve which supplies stimulation to the muscles of mastication
motor branch
congenitally missing teeth
hypodontia
probe angled to detect inter-proximal caries
Briault probe
probe used to detect soft tooth surfaces and to detect margins on existing restorations
angled probe
tooth mobility of side to side movement less than 2mm
grade 1
tooth mobility for side to side movement of more than 2mm
mobility for side to side and vertical movement also
vitality testing with cold stimulus
ethyl chloride
vitality can be tested with (3)
ethyl chloride, warm gutta percha or electric pulp tester
normal response to pulp testing
healthy pulp
increased response to pulp testing
early pulpitis present
reduced response to pulp testing
pulp is dying or tooth has heavily lined deep restoration present so voltage cannot be transmitted to pulp
no response to pulp testing
pulp is dead
two types of dental charting
FDI (federation dentaire international) and Zsigmondy-Palmer notation
CPITN stands for
community periodontal index of treatment needs
