Indications for a PMC:

- Asymptomatic (no pain, no swelling or sinus)

- No radiographic evidence of pulpal involvement or interradicular pathology

- Small carious lesions only - loss of no more than ⅓ of the marginal ridge. Any more indicates likely pulpal involvement due to large pulp horns of primary teeth e.g. > 1/2 dentine

22
New cards

Signs indicating pulpal involvement:

- Sinus (nb. interradicular abscesses may drain through the gingival margin rather than through a sinus in the mucosa)

- Swelling

- Radiographic pathology: the anatomy of primary teeth (notably the thin pulp chamber floor) means this often presents as interradicular radiolucency at the bifurcation.

- Pain which is spontaneous, severe or requires analgesia use.

- Radiographically visible deep caries.

- Extensive cavitation and loss of more than 1/3 of the marginal ridge. In these cases, it is very likely that there is pulpal inflammation.

- can lead to pulpitis

- when remaining dentine layer is thin, prov less protection to pulp for external stimuli, increasing risk irritation

- no chemical bone - microscopic gaps can form b/t filling & tooth

48
New cards

Formation of palatal shelves:

- 2 issue outgrowths - palatal shelves form on either side of maxillary prominences

- shelves: extension of maxillary prominences, growth vertically on either side of developing tongue within OC

49
New cards

Elevation and fusion of palatal shelves:

- as fetus growth, tongue descends, allows palatal shelves to elevate & move towards each other horizontally above the tongue

- once the palatal shelves are horizontally aligned begin to grow towards each other & eventually meet in midline

- medial edge epithelium - at point of contact dissolves, allowing underlying mesenchyme to fuse (creates continuous structure)

50
New cards

Fusion with primary palate and nasal sepia:

- secondary plate fuse w primary palate at incisive foramen

- forms U lip & ant most part of hard palate

- developing secondary palate also fuses w/ nasal septum superiorly, which completes the separation b/t oral & NC's

51
New cards

Development of hard and soft palate:

- ant portion of secondary plate ossifies to form hard palate

- posterior portion remains unossified, forming soft palate & uvula

New cards

Why does sertraline provide high caries risk?

SSRI

- xerostomia

- changes in oral pH

- diff cleaning teeth?

- increased risk ging/perio dx

- pot for increased sugar consumption

- red SF allows food particles & bacteria to accumulate on tooth surfaces.

- saliva contains bicarbonate ions, which neutralise acids produced by cariogenic bacteria. Without sufficient saliva, the oral env becomes more acidic, favouring demin of enamel.

- saliva is rich in Ca & PO4 ions, which are essential for remin enamel & maintaining its integrity. Xerostomia reduces the availability of these ions.

- dry conditions promote the adherence and growth of bacterial biofilms: harboring acidogenic bacteria that metabolise dietary sugars into acids.

- saliva contains antimicrobial proteins like lysozyme, lactoferrin, & immunoglobulins, which help control oral microbial populations. With red saliva, oral microbiome becomes more pathogenic, increasing caries risk.

- prev: sipping water, sugar-free gum, OTC

MOA:

> inhibiting the reuptake of serotonin into presynaptic neurons, increasing serotonin levels in the synaptic cleft. SSRIs also affect the autonomic nervous system, which plays a key role in regulating saliva production.

> can indirectly reduce parasympathetic stimulation of salivary glands. Saliva production is largely mediated by ACh acting on muscarinic receptors in salivary glands. By modulating neurotransmitter balance, SSRIs can interfere with this pathway, leading to reduced saliva secretion.

> may also affect the balance of sympathetic and parasympathetic innervation to salivary glands.
