5Post operative care for periodontal surgery is important. The wound may be [blank_start]dressed[blank_end], this keeps the wound [blank_start]clean[blank_end], controls [blank_start]bleeding[blank_end], and maintains [blank_start]close[blank_end] approximation of flaps or grafts.
The patient should be given post-operative advice in both [blank_start]verbal[blank_end] and [blank_start]written[blank_end] forms. In the first 24 hours;
- Avoid vigorous [blank_start]rinsing[blank_end] of mouth
- Avoid excessive [blank_start]exercise[blank_end] or alcohol
- Prescribe [blank_start]analgesia[blank_end]
- [blank_start]oozing[blank_end] at the surgical site is normal
- If bleeding lasts more than [blank_start]20[blank_end] minutes seek help
After 24 hours;
- Rinse around site with [blank_start]chlorhexidine[blank_end] mouthwash twice daily
- Clean other teeth as [blank_start]close[blank_end] as possible to the surgical site- Adressed
- Bclean

6The goals of periodontal surgery include:
Thorough [blank_start]cleaning[blank_end] and smoothing of [blank_start]root[blank_end] surfaces with [blank_start]direct[blank_end] vision
Reduce plaque [blank_start]retentive[blank_end] areas, for example [blank_start]pockets[blank_end]
Eliminate [blank_start]inflammation[blank_end] and pocket activity
Enhance [blank_start]regeneration[blank_end] of periodontal tissues
Create physiologic [blank_start]morphology[blank_end] of marginal tissues and muco-gingival border- Acleaning

11Gingivectomy is an example of [blank_start]resective[blank_end] periodontal surgery. It can be used for gingival [blank_start]enlargement[blank_end], and over [blank_start]supra[blank_end] bony pockets. It can [blank_start]eliminate[blank_end] periodontal pockets and achieve good soft tissue [blank_start]morphology[blank_end].
An incision is made with a [blank_start]45[blank_end] degree bevel angled towards the [blank_start]base[blank_end] of the pocket. The incision is made totally within the [blank_start]attached[blank_end] gingiva. Following removal of gingival tissue, the root surfaces are [blank_start]planed[blank_end] and the gingival surface may be contoured ([blank_start]gingivoplasty[blank_end])
A periodontal [blank_start]pack[blank_end] may be placed over the wound for 7-14 days while it heals by [blank_start]secondary[blank_end] intention.
Gingivectomy must not be carried out where the attached gingiva is [blank_start]narrow[blank_end], there are [blank_start]infra[blank_end]-bony pockets, or there is a need for [blank_start]osseous[blank_end] recontouring.
Patients may experience post operative [blank_start]pain[blank_end] or recession, which in turn can predispose them to [blank_start]sensitivity[blank_end], [blank_start]root[blank_end] caries, or poor [blank_start]aesthetics[blank_end].- Aresective

12Which of the following is a fully reflected flap?
- AModified Widman Flap
- BApically Repositioned Flap
13Fully reflected flaps have the following advantages:
They give good [blank_start]vision[blank_end] of the surgical site - which aids decisions about [blank_start]osseous[blank_end] recontouring, [blank_start]root[blank_end] resection, the need for [blank_start]grafts[blank_end]
[blank_start]Vertical[blank_end] incisions allow the flap to the replaced apically- Avision
- Bosseous
- Croot
- Dgrafts
- EVertical
14Apically repositioned flaps are carried out in the following way:
1. A [blank_start]scalloped[blank_end], inverse bevel incision is made - this releases [blank_start]pocket[blank_end] epithelium and [blank_start]inflamed[blank_end] connective tissue from the flap
2. [blank_start]Vertical[blank_end] relieving incisions are made
3. [blank_start]Intracrevicular[blank_end] incisions are made
4. The flap is [blank_start]reflected[blank_end]
5. The separated pocket linings and connective tissue collar is [blank_start]removed[blank_end]
6. The [blank_start]roots[blank_end] are derided
7. The flap is replaced [blank_start]apically[blank_end] and sutured
8. A [blank_start]dressing[blank_end] is placed, and the patient is booked in for [blank_start]review[blank_end] after being given [blank_start]post[blank_end] operative advice.
occasionally, but rarely, [blank_start]osteoplasty[blank_end] is indicated to remove non-supporting bone and improve bone architecture- Ascalloped

19A classic distal wedge excision is an example of [blank_start]resective[blank_end] periodontal surgery. It [blank_start]eliminates[blank_end] pockets distal to the last standing tooth/[blank_start]lone[blank_end] standing teeth.
Classic distal wedge excision technique;
1. Incisions are made in a [blank_start]triangular[blank_end] wedge that meets at the [blank_start]base[blank_end] of the pocket
2. The second incisions [blank_start]undermine[blank_end] and thin the buccal and lingual flaps
3. The flaps are [blank_start]repositioned[blank_end] and sutured, thus eliminating the pocket- Aresective
- Beliminates

- Dtriangular
- Ebase
- Fundermine
- Grepositioned
20A modified distal wedge excision is an example of a [blank_start]resective[blank_end] periodontal surgery to [blank_start]eliminate[blank_end] pockets.
The procedure is as follows:
1. [blank_start]Crescent[blank_end] shaped inverse bevel incision is made from the mid-[blank_start]buccal[blank_end] surface to the mid-[blank_start]palatal[blank_end] surface of the tooth. Then an [blank_start]intracrevicular[blank_end] incision is made
2. Wedge shaped [blank_start]parallel[blank_end] incisions are made distally
3. a perpendicular incision is made
4. [blank_start]Undermining[blank_end] incisions are made to [blank_start]thin[blank_end] the flap and for reflection - the soft tissue [blank_start]wedge[blank_end] is freed from the bone.
5. Flaps are [blank_start]sutured[blank_end]
6. Coagulum fills the bony [blank_start]crater[blank_end]
7. Redundant tissue is removed with [blank_start]scalpel[blank_end] or electrosurgery - [blank_start]contouring[blank_end] gingivectomy- Aresective

21Surgical removal of all or part of the root of a multi-rooted tooth is an example of...
- ARoot resection
- BHemisection
- CApicectomy
22Hemisection differs from root resection in what way?
- AA portion of the crown is removed in hemisection
- BThe crown is left intact in hemisection, only removing part of the root
- CHemisection does not require elective root canal therapy
- DRoot resection involves removal of the tip only
23Reparative surgical techniques include
- AModified widman flap
- BApically repositioned flap
- CDistal wedge excision
- DGuided tissue regeneration
- EPartially reflected flaps
- FOpen curettage
24Partially reflected flaps are an example of [blank_start]reparative[blank_end] periodontal surgery. The aim is to [blank_start]heal[blank_end] the periodontal pocket with [blank_start]minimal[blank_end] loss of tissue, not necessarily to [blank_start]eliminate[blank_end] pockets. They allow access to clean [blank_start]root[blank_end] surfaces. The may also promote bony [blank_start]infill[blank_end] in the defect with some crystal resorption and an overall resultant [blank_start]reduction[blank_end] in defect size. These procedures heal with long [blank_start]junctional[blank_end] [blank_start]epithelium[blank_end].

25A modified widman flap is an example of a...
- AFully reflected flap
- BPartially reflected flap
- CRegenerative procedure
26A Modified Widman flap is carried out in the following way:
1. An inverse [blank_start]bevel[blank_end] incision is made up to [blank_start]1[blank_end]mm from the [blank_start]gingival[blank_end] margin buccally and palatally to separate the pocket [blank_start]epithelium[blank_end] and inflamed connective [blank_start]tissue[blank_end] from the flap
2. Intra-[blank_start]crevicular[blank_end] incisions are made, then a [blank_start]horizontal[blank_end] incision made to separate supracrestal pocket tissue
3. A [blank_start]full[blank_end] thickness flap is reflected, but not beyond the [blank_start]mucogingival[blank_end] line
4. Root surfaces are debrided with [blank_start]direct[blank_end] vision, and curettes used to [blank_start]remove[blank_end] tissue from interdental [blank_start]craters[blank_end]
5. Osseous defects are [blank_start]curetted[blank_end]
6. Flaps are replaced over bone and teeth, and sutured. Ideally they should completely cover [blank_start]interdental[blank_end] bone- Abevel

28Modified widman flaps are useful in [blank_start]anterior[blank_end] segments where [blank_start]aesthetics[blank_end] is important as they preserve soft [blank_start]tissue[blank_end] and [blank_start]root[blank_end] coverage. They do not [blank_start]eliminate[blank_end] pockets but [blank_start]reduce[blank_end] pocket depths and heal by long [blank_start]junctional epithelium[blank_end], which is stable.
However, they can be highly [blank_start]technique[blank_end] sensitive and depend on the patient's [blank_start]healing[blank_end] potential. There is no [blank_start]new[blank_end] attachment and may leave interdental craters.- Aanterior

31Conventional flap therapy results in [blank_start]apical[blank_end] migration of epithelial cells and healing by long [blank_start]junctional[blank_end] [blank_start]epithelium[blank_end] attaching on to root surface. This does not mimic the original [blank_start]periodontal[blank_end] attachment. Guided tissue regeneration aims to reorganise migration of cells so cells from the [blank_start]periodontal[blank_end] [blank_start]ligament[blank_end] are able to [blank_start]proliferate[blank_end] into a healing site, resulting in a reformed periodontium rather than a repaired one.

35GTR is carried out by placing a [blank_start]membrane[blank_end] that excludes the oral [blank_start]epithelial[blank_end] cells and gingival connective tissue from [blank_start]tooth[blank_end] and bone. This creates a [blank_start]space[blank_end] around the cleaned root surface. This space is [blank_start]repopulated[blank_end] with cells that mature to form new [blank_start]periodontal[blank_end] ligament fibres which insert into [blank_start]bone[blank_end]. GTR can be used for [blank_start]infra[blank_end] bony pockets, [blank_start]2[blank_end] or [blank_start]3[blank_end] walled defects, [blank_start]furcation[blank_end] defects and recession defects.
