26
Cleft palate
located in the roof of the mouth can sometimes not develop correctly in the womb - tissue does not stick together
27
Tongue
Muscular organ, covered with pink tissue called mucosa rough bumps are called papillae - thousands of taste buds 2 parts - oral at the first and pharyngeal at the back, it is separated due to the lingual septum.
28
Lamina Dura/ Compact bone
Compact bone lies close to the periodontal ligament lamina dura surrounds the tooth socket appears as a hard thin layer of bone (white) - cribriform plate
29

31
philtrum
vertical indentation that is in the middle area of the upper lip, extends from nasal septum to the tubercle of the upper lip.
32
Lingual Frenum
located between the base of the tongue and the floor of the mouth, come in different sizes and can sometimes restrict the use of tongue.
33
Labial Frenum
connects the lip to the gum and is located between the upper and lower front teeth, can be sometimes to wide/long and creates a gap between upper central incisors.
34
Temporal bone
Base of the skull Protects the temporal lobe of the brain, the 12 cranial nerves and the middle/inner ear (hearing organs)
35
Zygomatic Arch
Protect the eye, origin masseter and part of the temporal muscles. Forms the ventral and lateral rim of the orbit.
36

41
Temporomandibular Joint TMJ
Formed by the articulation of the mandible and the temporal bone of the cranium. Located from the tragus of the ear on the lateral aspect of the face.
42
3 main joint movements:
1. Depression - open mouth 2. Mechanism - Gliding movement 3. Lateral / side to side - movement in chewing or grinding
43
TMJ Dysfunctions - Trismus
Lock Jaw Limited mobility of the jaw
44
TMJ Dysfunctions - Clicking
Jaw noise - when opening and chewing cartilage disc moves out of its normal position
45
TMJ Dysfunctions - Crepitus
Grating and grinding noise caused by the jaw. Advanced TMJ damage
46
Where is saliva produced and what is it made of?
Salivary glands Multiple electrolytes, sodium, potassium, calcium, magnesium, bicarbonate, phosphates.
47
what does saliva pick up when circling the oral cavity?
food debris, white blood cells and bacterial cells
48
Salivary glands - Ageing
reduced salivation leads to issues regarding dry mouth, more common in older people. Increase in age - number of acini reduces and the amount of fatty and fibrous tissue increases.
49
Salivary glands - Mumps
Viral infection. Swelling of one or both glands Requires attention from medical professionals
50
Salivary glands - Mucocele
Gathering of saliva outside of the salivary gland - rupture of the salivary duct. Tissues swell due to the rupture, tissues that swell tend to be under the tongue, back of the throat, around the eye.
51
Salivary stone
Small rocks made up of calcium and other minerals. Pain tends to occur when a stone completely blocks a duct, the saliva cant be passed into your mouth.
52
Why is it important to gain valid consent?
Legal principle to gain consent to any treatment/speaking to a patient. All options and costs should be discussed. Patients should sign a treatment estimate form prior to treatment to consent. Risks and outcomes
53
Mental capacity legislation
To be valid to consent a patient must have full capacity to understand the situation. - clear understanding If a patient is unable to do so they will bring someone along, parent, career to consent for them.
54
Patients with additional needs
Severe mental health conditions e.g. bipolar, dementia or disabilities do not consent to their own treatments. Consent from another can either be written, spoken or implied The practice must know who the person is that is signing for the patient. The dentist can sign for them if no one is able to.
55
Gillick consent
Consent relating to children under 16, if the child is competent enough to consent for themselves they can do so. The aim is to bring children into adulthood.
56
Montgomery patient centered approach to consent
Focus lies with the patient and their viewpoint. Warn patients of risk
57
Treatment planning and costs
Maintaining valid consent. All treatment and costs must be discussed with the patient. Consent must remain valid throughout.
58
Information governance
how to manage and share information safely and securely. reduces the level of risk date breaches and other security incidents.
59
what is information governance implemented with?
1. My practice 2. GDPR 3. Internal policies 4. Safegaurding
60
Acute Abscess
Caused by an infection of the root canal of the tooth. Toothache, headache, sensitivity, bad taste, swollen jaw/face Access the nerve, drain abscess, XLA, antibiotics
61
Denture stomatitis
Fungus candida - causes oral thrush pain when swallowing, soreness in mouth, white/red patcheson tongue, gums, lips, inner cheek, roof mouth. Topical therapy - clotrimazole or nystatin Denture should be removed
62
Angular Cheilitis
Skin condition that affects the corners of your mouth, develops painful and cracked sores ; bleeding, blisters, swelling, redness. Skin ointments that contain topical e.g. myostatin.
63
Traumatic ulcer
small shallow lesions that develop on the soft tissues in your mouth. Burning sensations, ulcers that are white grey yellow with a red outline. Need to be treated with tetracycline Non contagious
64
fissured tongue
Benign condition, many deep/shallow grooves or fissures on the back surface of the tongue. red patches dotted around, changes in location, discomfort/burning, Patients are encouraged to brush the top surface of the tongue to remove any debris that might cause infection.
65
glossitis
Problems when chewing, swallowing, or speaking surface of the tongue is sore, and can be red or pale with swelling. Good oral hygiene and antibiotics.
66
Frictional Keratosis
No symptoms other than those who bite their cheeks this can cause trauma leading to swelling, burning and pain of the tissue. Constant rubbing, chewing, sucking of the oral mucosa against teeth. Removing the friction by correcting restorations or dentures.
67
Pregnancy Epulis
Benign tumour that is harmless. Gum inflammation, swelling and bleeding. Any treatment should be postponed til after birth.
68
Herpes Simplex - cold sores
Located on the inside of the mouth, can cause damage to the soft tissue of the gums. Appointments should be re-arranged and cancelled due to the aerolisation - nurse and dentist are vulnerable for infection.
69
Diabetes
Increased blood glucose levels = dry mouth due to medication (steroids). Lead to plaque build up, decay, cavities. Patients should be seen to around the time of their diabetes check with GP as the gums can take a while to heal if deep cleaned.
70
Epilepsy
Higher risk of bleeding gums, dry mouth, inflammation of soft tissues, possible caries and gum disease. Adrenaline free LA
71
Pregnancy
Increase of hormones progesterone and oestrogen, can temporarily loosen the tissues and bones that keep your teeth in place. No x-rays Be careful when reclining the chair for someone who is heavily pregnant. Regular cleans Treatment e.g. fills should be left til after birth. 3-6 month check ups.
72
Bleeding disorders
Haemophilia A - someone who cannot form a proper blood clot Can cause poor oral health, plaque must be removed to prevent periodontal disease and caries. Gingival bleeding XLA & SCALES cause bleeding patient should be checked prior treatment by their hematologist to confirm the treatment is okay to do so.
73
Osteoporosis
Caused from aging, menopause, lack of nutrients - leads to gingivitis and periodontal disease - loss of teeth. It also has a negative impact on the jawbone that supports the teeth Dentures tend to not fit correctly due to bone density - oral surgery referral is usually done.
74
Cancer
Chemotherapy and radiation affect the oral tissues, can cause a disruption in a healthy balance of bacteria by affecting the saliva being produced - tooth decay and infections. 3 month check ups Dry mouth - prescribed fluoride toothpaste
75
who would be a patient viewed as high risk?
Patient with poor OH Periodontal disease Several restorations Medications 3 month recall
76
who would be a patient viewed as low risk?
Not many fillings controlled gum health medically fit and well 6 month recall
77
Reason for the recall system?
To check on the patients wellbeing, general health and preventative habits.
