The Mouth Flashcards
what is the preferred term between buccal and oral cavity
oral
is there differentiation between oral health and general health
no
what is periodontitis
loss of attachment between the gingiva and the tooth
what is gingivitis
inflamed gums
what colour does calculus appear as
black - it is hardened dental plaque
what is caries
dental decay and loss of hard dental tissue, can be reversed. i
what can caries be caused by
lack of saliva due to radiation, xerostomia, blood pressure prescriptions
explain the oral ecosystem
teeth, saliva, microflora, and mucosa. caries can have more specialised microflora that can produce the acid necessary for generating caries.
there is endogenic input, such as microorganisms changing the behaviour of the mouth which can affect the centre of the ecosystem. exogenic input comes from illness, oral disorders etc which generate an output of oral health.
there is also how people behave, which coincides with societal influences.
how does society have an impact on the oral health of individuals
links to the aesthetic expectation, how people expect their mouths to look, and social economic factors like being able to afford healthier foods that are better for teeth
provide advice to the patient to help with lifestyle factors that can contribute to poor oral health
how can the oral cavity be described as an environment
there is geography (attachment of the tooth), resources (nutrients for the tooth), which are supplied by saliva (climate). pH is also part of the climate of the oral environment. saliva includes many important components like liquid, water, and buffers
what is the natural history of disease and its prevention
in the healthy phase there must be an equilibrium between the host tooth and the agent (tooth and microorganisms)
when it is irreversible we must enter the secondary intervention process, the clinical horizon, what we can act upon and try to prevent or do we try to restore. restoration depends on primary intervention.
what are the different functions of the mouth
- digestive
- protective
- aesthetic
- speaking
- playing instruments
what are the three bones found within the oral cavity
the mandible, the maxilla and the palatine bones
what is involved in the maxilla bone
this forms the upper part of the jaw, and contains alveolar processes which is what the horseshoe shape arises from. within these alveolar processes are dental alveoli where the teeth rest in
what is involved in the mandible
this is the lower part of the jaw and also contains this alveolar process
where are palatine bones found within the mouth
on the roof, fusing together to form the midline of the maxilla
what can the oral cavity be divided into
the oral vestibule and the oral cavity proper
what is the oral cavity proper
the space contained between the upper and lower dental arches. stretches from the inner surface of the teeth and communicates with the oropharynx
what is the oral vestibule
this is the space between the teeth and the inner mucosal lining of the lips and cheeks. this continues onto the gingiva to form the superior and inferior boundaries of the vestibule
what is the retromolar fossa
the space between the third molar teeth and the ramus of the mandible
what can the roof of the mouth be divided into
the soft and hard palate
give an overview of the hard palate
this is the bony, dome shaped structure that makes up the anterior of the roof of the mouth. the upper surface of the hard palate forms the floor of the nasal cavity and is lined by the respiratory mucosa.
the lower surface of the hard palate that can be viewed from the mouth is lined by the palatal gingiva
give an overview of the soft palate
this makes up the posterior section of the roof of the mouth and separates the oropharynx from the nasopharynx. it is boneless and moveable, and is made up of fibrous aponeurosis, muscles, and non keratinised mucosa. it is also covered by the oral mucosa inferiorally and the respiratory mucosa superiorally
what is the mylohyoid muscle
this forms the muscular diaphragm that supports the tongue and other structures of the floor of the mouth
what is the function of the palate
to separate the oral cavity from the nasal cavity
