Q

How to manage MIH manifesting as mild enamel opacities without enamel breakdown on first permanent molars?

A

Prevention - high risk, fluoride toothpaste at least 1450ppm F, fissure seal with resin sealant, fluoride varnish 2.2% up to 4 times yearly, daily 225ppmF- rinse, investigate diet and advise
Manage sensitivity - casein phosphopetide amorphous calcium phosphate tooth mousse, fluoride mouthwash and varnish
May need nitrous oxide sedation to help with compliance because teeth may be tricky to anaesthetise

Q

How to manage MIH manifesting as mild enamel opacities with enamel breakdown on first permanent molars?

A

Stabilisation - glass ionomer cement, consider orthodontic referral to discuss long term plans for retention of these molars and discuss extractions at appropriate age/stage of dental development
May need nitrous oxide inhalation sedation to help with compliance as teeth may be difficult to anaesthetise
Restorations - GIC or RMGIC not recommended in stress bearing areas and can only be used as intermediate restoration, composite resin is the material of choice, using LA and rubber dam

25
What is infra occlusion and how is it graded?
Teeth that fail to maintain their occlusal relationship with opposing teeth, previously called submerged or ankylosed. Most commonly affects deciduous lower molars. Grade 1 - the occlusal surface is above the contact point of the adjacent tooth Grade 2 - The occlusal surface is at the contact point of the adjacent tooth Grade 3 - the occlusal surface is below the contact point of the adjacent tooth
26
What percentage of primary molars become infraoccluded?
8-14%
27
How would you manage an 11 year old with an infraoccluded lower second deciduous molar?
Take a radiograph to see if there is a permanent successor If there is one, it is likely that this infraoccluded tooth will exfoliate at around the same time as the contralateral, when the permanent successor starts to erupt
28
When would you refer an infra occluded lower second molar for surgical removal?
When there is no permanent successor and the tooth will probably disappear below the gingival margin
29
If a tooth is infraoccluded below the gingival tissue, and there is a permanent successor what could have happened to the deciduous? What needs to be considered after removal of the deciduous molar?
IT may have become ankylosed Space maintenance for the permanent successor will need to be considered after extraction
30
12 year old patient has fallen and hit 11 and 21 which are now mobile and the crowns palatally displaced What special tests would you carry out?
Periapical radiographs to check for root fractures Sensibility testing
31
12 year old patient with 11 and 21 middle third root fractures. The teeth are mobile and the crowns palatally displaced. How would you treat this?
Splint the teeth using a flexible splint that allows physiological tooth movement A wire splint that is bonded to the inured teeth and one healthy tooth on either side of the injured teeth used acid etched composite (easy to construct and well tolerated) The splint must be kept in place for 4 weeks
32
Middle third root fracture of 11 in a 12 year old Coronal portion of the pulp becomes non vital How would you manage this?
Extirpate the pulp up to the fracture line Fill the root canal with non setting calcium hydroxide to encourage barrier formation coronal to the fracture line Change CaOH every 3 months until barrier is formed, at which point obturate the coronal root with GP and keep the tooth under review
33
How to treat dentoalveolar fracture?
Reposition and splint for 4 weeks
34
What is behavioural management?
A way of encouraging a child to have a positive attitude towards oral health and healthcare so that treatment can be carried out.

38
In a 15 year old with a retained, mobile upper C how would you determine whether the canine was present?
Clinical examination - angulation of the lateral incisors - a buccally placed ectopic canine might push the apex of the lateral palatally making the crown proclined Palpation of the buccal sulcus and palate may reveal a bulge Radiographs are the definitive method of determining presence
39
Explain how you would use an OPT and a PA to determine the position of an unerupted tooth
Parallax technique When two views are taken with different angulations, any object that is further away from the tube will move the same direction as the tube This can be applied in a horizontal or vertical direction With these two views, OPT has been taken from a near horizontal position and the PA has been taken from a higher angulation If the canine tooth appears lower on the OPT than the PA then it is palatally placed
40
Combinations of radiographs that can be used for parallax
Two PAs from different horizontal angulations A PA and an upper occlusal An upper occlusal and an OPT
41
What type of appliance are Andresen Frankel Twin block How do they work?
Functional appliances They use, guide, or eliminate the forces generated by the orofacial musculature, tooth eruption and facial growth to correct a malocclusion
42
What age group are functional appliances most effective in?
Growing children Preferably before the pubertal growth spurt as they use the forces of growth to correct the malocclusion
43
Which type of malocclusion is most successfully treated with functional appliance? What skeletal effects are thought to occur?
Class II especially div 1 Can also be used to treat AOB and class III Thought to provide a combination of skeletal and dental effects The mandible is stimulated to grow and the glenoid fossa remodels forwards as the appliances pull the condylar cartilage forwards It is also claimed that maxillary growth is inhibited
44
Name two skeletal and two dental changes that are reported to occur with the use of functional appliances
Skeletal Restraint or redirection of forward maxillary growth Optimisation of mandibular growth Forward movement of glenoid fossa Increase of lower facial height Dental changes Palatal tipping of upper incisors Labial tipping of lower incisors Inhibition of forward movement of maxillary molars Mesial and vertical eruption of mandibular molars
45
What determines the response of a tooth when force is applied to it?
Magnitude and duration
46
What changes are seen in the PDL when orthodontic forces are applied to teeth?
Tension side - stretching of the PDL fibres and stimulation of the osteoblasts on the bone surface leading to bone deposits Compression side - Compression of blood vessels, osteoclast accumulation which results in resorption of bone and formation of Howship lacunae into which fibrous tissue is deposited

55
Name 4 caused of a midline diastema
Physiological Small teeth in larger maxilla Missing teeth Midline supernumerary, odontome Proclination of upper segment Prominent frenum
56
How would you determine the cause of a midline diastema?
History and examination Look for a prominent frenum (pull the lip to put under tension and look for blanching of the incisive papilla), proclined upper incisors, size of the teeth in the segment Radiographs will help confirm if any teeth are missing or the presence of supernumerary. A notch of the interdental bone between the upper centrals is another sign of prominent frenum
57
Once you have determined the cause of a midline diastema how should the patient be managed?
- If upper 3s UE and diastema <3mm then reassess once 3s erupted - If upper 3s are UE and diastema >3mm then ortho may be needed when 3s erupt - If upper 3s are erupted the incisors require ortho or restorative to close gap - If there is a prominent frenum, refer for surgical opinion - If supernumerary refer for surgical removal

62
At what stage is ortho treatment needed in CLP?
Mixed and/or permanent dentition Mixed dentition - proclination of the upper incisors may be necessary if they erupt in lingual occlusion, ortho expansion of collapsed arch and alignment of upper incisors is required prior to alveolar bone grafting Permanent dentition - fixed appliances are usually required for alignment and space closure Orthognathic surgery and associated ortho when growth completed Pts classically have a hypoplastic maxilla with class III and orthognathic surgery is for improvement in aesthetics and function
63
What may need to be carried out to aid eruption of maxillary canine on the cleft side in CLP patients and when would this be done?
Alveolar bone grafting of cancellous bone from another site eg hip or tibia, to the cleft alveolus age 8-11 - canine is 2/3rds root formed Creates a one piece maxilla, gives the canine bone to erupt into, provides bone to support the alar base of nose, intact arch to allow ortho movement, aids closure of oronasal fistula
64

65
Compensating extractions
Extraction of the same or adjacent tooth in the opposing arch on the same side
66
Is the effect greater or less with the premature loss of a deciduous first molar than with a canine?
A centreline shift will occur to a lesser degree with the unilateral loss of a deciduous first molar than a canine
67
What would you recommend in a crowded mouth required unilateral loss of an upper canine?
The unilateral loss of a canine should be balanced as the correction of a centreline discrepancy is likely to need fixed appliance and prevention is preferable
68
What is the effect if premature loss of a deciduous second molar?
Associated with forward migration of the first permanent molar, this is greater if the deciduous second molar is lost before the eruption of the first molar, so if possible delay until the first permanent molars are in occlusion
69
Do you compensate or balance the loss of deciduous second molar?
Neither
