Q
SDCEP caries prevention guidance
A
Give toothbrushing advice at least once a year:
- Brush at least twice daily, in the morning and last thing at night,
- Use the correct amount of a toothpaste with age-appropriate fluoride concentration:
- Under 3 years old: use a small smear of paste containing not less than 1000 ppm fluoride
- 3–6 years inclusive: use a pea-sized amount of paste containing not less than 1000 ppm fluoride
- 7 years old or over: use paste containing 1350–1500 ppm fluoride
- Spit, don’t rinse.
- Help children under 7 years old and continue to supervise older children until confident in their brushing habits.
In the early stages of providing care give hands-on brushing instruction.
Give dietary advice at least once a year:
- Restrict foods and drinks containing sugar to meal times.
- Drink only water or milk between meals.
- Snack on sugar free snacks (e.g. fresh fruit, carrots, peppers, breadsticks, occasionally a little cheese).
- Do not eat or drink after brushing at night.
Be aware of hidden sugars in some foods and the acid content of drinks. Apply sodium fluoride varnish (5%) twice a year to children over 2 years of age

**Preventive multi-agency management**
‣ liaise with other professionals (e.g. health visitor, school nurse, general medical practitioner, social worker) to see if concerns
are shared
‣ A child may be the subject of a CAF (Common Assessment Framework) at this level.
‣ Check if child is subject to a child protection plan (which replaced the child protection register)
‣ Agree joint plan of action, review at agreed intervals
‣ Letter to Health Visitor of children \< 5 who fail appointments and have failed to respond to letter from dental practice
๏ “If this family is known to you, we would welcome working together to promote their oralhealth.”
**Child protection referral**
‣ In complex or deteriorating situations
‣ Follow local guidelines
‣ Referral is to social services
๏Usually by telephone followed up in writing

Oral mucositis refers to the oral erythematous and ulcerative
lesions commonly observed in patients undergoing cancer
therapy.
They are painful and affect nutrition and quality of life of the patient, and contribute to local and systemic infections
Radiation induced mucositis is initiated by direct injury to basa epithelial cells and cells in the underlying tissue. DNA-strand breaks can result in cell death or injury

vital tooth pulpotomy
Indications
- Carious or traumatic exposure of a bleeding pulp
- Radicular pulp preserved and bleeding controlled
- Pt able to take LA and rubber dam
Procedure
- Access - High speed bur
- Amputation - Haemorrhage control with Ferric Sulphate 15.5% for 20s (N.B If anterior or permanent then use saline!)
- Restoration - cover with CaOH, GI Core, PFMC
Pulpal Evaluation
- Normal bleeding - Uninflamed - bright red and good haemostasis
- Abnormal bleeding - Inflamed - deep crimson and continued bleeding after pressure
Apexogenesis
1. Radicular pulp left
2. Calcific barrier formed over the radicular pulp with CaOH
3. Permits normal physiological apexogenesis of the root
\*Cvek Partial Pulpotomy is indicated where there is a exposed pulp \<24 hours
87
non vital tooth pulpectomy
Indications
- Excellent pt cooperation
- Hyperaemic pulp
- Pulp necrosis
- Caries into furaction
- Irreversible pulpitiis
- PA PDitis
- Chronic Sinus
- N.B if severe infection with facial swelling then AB’s and extraction
Procedure
- Use slow speed bur or excavator
- Remove contents of pulp chamber
- Instrument to 2mm short of apex
- Irrigate with CHX 0.2%
- Dry with paper points
- Obturate with Vitapex - CaOH and Iodoform paste OR MTA (leave for 30 mins to form apical barrier) and Gutta percha
➡ CaOH can dessicate dentinal proteins causing premature root fracture
- Seal with mix of ZOE/GI
- Take PA radiograph
- Restore with PFMC
Apexification
- Induces formation of osteocementum in a pulpless tooth via chemical means e.g CaoH or MTA
- very rarely normal root development may take place
- takes 9 months
88
fissure sealants
- Protective plastic coating used to seal fissures and pits to prevent food and bacterial accumulation that can cause caries
- Isolate under single tooth dam
- Tie ligatures into both holes of the clamp
- Can alternartively use Cotton wool rolls and parotid guard
Indications
1. High risk children
2. Medically compromised
3. Learning difficulties
4. Permanent Molars, Cingulum pits upper incisors, buccal pits lower molars, palatal pits upper molars
Procedure
1. Etch with 37% Orthophosphoric acid
2. Wash off etch
3. Bis-GMA resin painted onto fissure pattern
4. No air blows
5. Cure
6. use probe to try and flick off - should be smooth and glassy
89
XLA of FPMs
- may help with spacing later on if prognosis poor
- optimal occlusal relationship attained when
* Bifurcation of lower 7 is formed on an OPT - 8.5-10 years
* 5’s and 8’s are all pfesent and in good position
* Mild buccal segment crowding
* Class I incisor relationship
16/26
* Loss before complete eruption of 7 - 7 rotates
36/46 \>
* Loss after optimum age - tilting 7’s - tilts mesially
* Loss before optimum age - 5’s drift distally and rotate - rotates to form arbitrary occlusal contact
90
microabrasion
Associated with
‣ Amelogenesis Imperfecta
‣ Trauma related staining
‣ MIH
Procedure
1. Dental Dam with ligatures
2. Polish the teeth pumice and water
3. Apply Sodium bicarbonate to the cervical areas of the dam to create an alkaline barrier
4. Apply 18% Hydrochloric acid or Opalustre 6%
5. Use wooden popsicle stick to scrub on for 5 secs
6. wash off with very good aspiration
7. Dry teeth and reapply bicarb and start again
8. Gold standard is 10 rounds of therapy
Works best on Brown staining
White stains can actually look worse and go yellowish
Best to do one tooth at a time so as not to over treat with acid, if doing \>2 teeth as part of treatment, can remove the labial profile
91
pulp canal obliteration
- Narrowing of the pulp chamber and or root canal by dentine
- mediated by odontoblasts, but not really known why this is
- It will have a vital response but will be reduced
- Tx - Do nothing but monitor vitality as only 1% form a PA area
- Crown takes a yellow appearance - vital bleaching
92
sequalae if trauma to primary tooth
Delayed eruption
- Damage to perm tooth germ
- Dilaceration of root
- Odontome formation
- Hypoplasia of enamel
- Hypomineralisation
- Root resorption
