Question

What are the treatment options for the BPE scores?

Answer 1

``` 0 - OHI 1 - OHI 2 - OHI and removal of PRF 3 - OHI, scaling and root planing 4 - OHI, scaling, root planing (surgical or non surgical) ```

Answer 2

smoking, poorly controlled diabetes

Answer 3

tooth is usually vital pain on lateral movements tooth usually mobile loss of alveolar crest on x-ray

Answer 4

tooth is usually non-vital TTP vertically tooth may be mobile loss of lamina dura on x-ray

Answer 5

Oral hygiene instruction, mechanical plaque control (tooth brushing and interdental cleaning), chemical plaque control scaling and root surface debridement

Answer 6

poor plaque control systemic diseases smoking teeth with poor long term prognosis

Answer 7

apically repositioned flap, osseous surgery (osteoplasty, ostectomy), furcationplasty, tunnel preparations, root resection, hemisection, extraction, gingivectomy guided tissue regeneration (bone grafts, enamel matrix derivatives), mucogingival surgery (free grafts or pedicle grafts)

Answer 8

success of treatment is characterised by reduction in BOP, reduction in pocket depth and change of gingival contour. need constant monitoring of BOP and pocket depths and plaque levels and radiographs 6ppc 8-12 weeks after treatment

Answer 9

Class I - recession does not extend past MGJ, no interdental bone loss Class II - recession just beyond MGJ, no bone loss Class III - recession to or beyond MGJ, some interdental bone loss, no movement of teeth Class IV - recession to or beyong MGJ, interdental bone loss, malpositioned teeth

Answer 10

anyone who has had perio treatment. if pts arent given supportive therapy they are 6x more likely to lose teeth 3month intervals for sub and supragingival plaque removal. OHI. 6PPC every 12 months (SDCEP guidelines)

Answer 11

1. examination - looking for anything that can affect their plaque retention factors and what factors have changed since last evaluation 2. treatment options - scaling and RSD - but not <3mm sulci 3. reporting, cleaning, scheduling for further treatment - motivation, check reason for recurrence

Answer 12

* Inadequate or insufficient treatment that has failed to remove all the potential factors favoring plaque accumulation. * Incomplete calculus removal in areas of difficult access. • Inadequate restorations placed after the periodontal treatment was completed. * Failure of the patient to return for periodic checkups. This may be a result of the patient's conscious or unconscious decision not to continue treatment or the failure of the dentist and staff to emphasize the need for periodic examinations. * Presence of some systemic diseases that may affect host resistance to previously acceptable levels of plaque.

Answer 13

- root surface debridement - cause related therapy - nothing - open flap curattage

Answer 14

``` explain risks explain benefits explain what happens if no treatment likely chance of success other possible treatment options explains the cost ```

Answer 15

- MI or angina - ask pt if they have had this before - ABCDE - give O2 - 15L/min with non rebreather mask - sublingual GTN 2x400ug actuations (repeat after 3 mins) - call ambulance - give 300mg crushed asprin

Answer 16

need to wait at least 6 weeks, best 8 to assess whether junctional epithelium has reattached, but not too long as can get re-colinisation and calculus preventing healing and need to re-treat

Answer 17

``` no BOP reduction in pocket depts to <4mm increased tone of ep reduction in gingivitis and inflammation reduction in plaque and calculus levels ```

Answer 18

HPT correct any premature contact areas dahl appliance if severe BRA at night

Answer 19

``` attachment loss widening of PDL morphology roots length of roots inflammation PA lesions trauma ```

Answer 20

``` Hx of the infection Rx of infection administer LA establish drainage - through pocket or incise the heaviest part of abscess gentle sub gingival debridement HSMW if systemic - metronidazole 400mg TID 5 days HPT and maintenance ```

Answer 21

These need treatment of the perio condition - so sub gingival RSD and RCT to treat endo

Answer 22

on any sextant scoring 3 whole mouth if any sextant scores 4 before and after treatment (SDCEP_) after treatment only (BSP)

Answer 23

``` mobility pocket depth LOA BOP teeth present furcal involvement sites with LOA ```

Answer 24

``` assumes average root lengths probing force/angulation calculus inflammation cooperation ```

Answer 25

``` furcationoplasty sectioning the tooth after RCT guided tissue regenetation expose more of the furcation to ease cleaning XLA ```

Answer 26

``` occlusal trauma (glickmans theory) zone of destruction from plaque and thickness of cortical bone (waerhaugs theory) plaque traps ```

Answer 27

``` rate of destruction age of patient medical history family history sites affected degree of bone loss general OH ```

Answer 28

ultrasonic debridement hydrogen peroxide MW/CHX OHI metronidazole 400mg TID 3 days

Answer 29

``` post oral surgery post periodontal surgery full mouth disinfection where OH is difficult root canal irrigant RAS chemotherapy pts to maintain OH ANUG candidal infection if at risk of secondary infection with PHG ```

Answer 30

``` adhesion colonisation accumulation develop complex community disperse ```

Answer 31

``` biofilm formation LPS endotoxin production fimbrae for adhesion and invasion proteases complex plysaccharide production ```

Answer 32

``` immunoglobulins lipase lysozyme mucins lactoperoxidase lactoferrin amylase ```

Answer 33

``` beefy tongue RAS gingivitis burning mouth/dysasthetia glossitis angular cheilitis ```

Answer 34

``` gingival hyperplasia bleeding petechiae ulceration swellings predisposition to infections ```

Answer 35

heart valve replacement atrial fibrillation thrombophilia ischaemic stroke

Answer 36

``` check with their consultant infiltrations, not blocks simple treatments not disrupting the gingivae supragingival scaling restorations ```

Answer 37

infrabony - one wall, two wall, three wall. interproximal crater

Answer 38

acute exacerbation of existing perio disease (from trauma or blockage) LA, incise, drain, gentle pocket debridement short of base - stops spreading infection. OHI, CHX, HSWM, XLA is possible. ABs if systemic/immunocompromised. HPT and review

Answer 39

generalised = 3 tteh other than 6s and 1s localised - patient is generally healthy, rapid loss off bone, familial aggregation, low levels of plaque, around 30s onset If there is a cause - then it is not aggressive perio - it is perio secondary to the cause

Answer 40

daily removal of plaque and modify behaviours

Answer 41

leukotoxin, endotoxin, collagenases, fibroblast inhibitory factor, soluble heat labile factor

Answer 42

smoking genetics inherited diesases papillon lefevre syndrome

Answer 43

probe - can use neighbour probe for finding furcation | radiographically

Answer 44

I - up to 3mm horiztontal attachment loss II - >3mm horizontal attachment loss, not through and through III - through and through

Answer 45

repair - NST, ST regenerate - GTR, graft eliminate - tunnel, root resection, hemisection, XLA palliate - supportive care NST is best for grade I

Answer 46

``` iatrogenic toothbrushing traumatic occlusion trauma fraenal attachments - high or aberrant ```

Answer 47

free soft tissue (free ginigval, connective tissue) pedicle soft tissue (rotational, laterally positioned, transpositional) advanced flap (coronally/semilunar coronally positioned)
