Objectives of surgical phase of periodontal surgery
•Regeneration of lost periodontal attachment.
•*mprovement of the prognosis of teeth and their replacements.
•*mprovement of esthetics.
PREOPERAT!E "#OR$ATO"
Case %istory
Medical history
+he operator should determine if specific preoperative modifications are indicated ecause of
patients medical history, well efore scheduling any surgical procedure. -rug allergy, patients
medication or systemic disease dictate alterations in the type of anesthetic agent, analgesics, prophylactic antiiotic and even surgical procedure.
ndications for Periodontal Surgery
i. "orrection of gross gingival aerrations.
ii. Persistent inflammation in areas with moderate to deep pockets.iii. Areas with irregularly ony contours, deep craters.
iv. (hen removal of root irritant is not possile due to deep pockets especially in molars and premolars.
v. Furcation lesions.
vi. *nfraony pockets on the distal areas of last molars, complicated y mucogingival prolems.
Contraindications for Periodontal Surgery
i. ncooperative patient
ii. ncontrolled systemic diseases#hormonal disordersa. ncontrolled diaetes mellitus
. Adrenal dysfunction
iii. !lood disorders
iv. )moking
v. "ardiovascular diseases
a. /ypertension . 0yocardial infarction
c. Angina pectoris
d. Anticoagulant therapy
e. Rheumatic fever
vi. 1rgan transplantation
vii. 2eurological disorders
a. 0ultiple sclerosis . Parkinsons disease
Consent
Patient should e fully informed verally and in writing aout the details of the procedure and
possile complications. Patient should e given agreement for the procedure oth with an oral
statement and y signing a consent form.

Pre&edications
Premedication should e given when indicated. +h chemotherapeutic agents used for premedications are:
i. Anxiolytics: Apprehensive and neurotic patients are given antian3iety, sedative, hypnotic
agents, tran$uili4ers or ariturates im or iv prior to surgical therapy.ii. Antibiotics: Given to only medically compromised patients such as infective endocarditis or
patients who re$uire prophylactic antiiotics regimen 5valvular heart disease6. Antiiotics should
e given one hour efore surgery to attain ade$uate levels so as to prevent acteremia.
iii. Antiseptics: 1ral rinse with 7.89 "/; gluconate mouthwash.
iv. Nonsteroidal Anti-inflammatory drugs (NSAIDs): *uprofen can e given as premedication
efore surgery.
Patients on anticoagulant therapy#aspirin shouldstop such medicines < to 8= days efore surgeryand > to = days afterwards with physicians approval.
"TRAOPERAT!E CO"S'ERATO"S
$onitoring Presurgical 'ata+he data necessary to select the surgical procedure includes periapical radiographs, study casts
and proing charts.
Anesthesia
Periodontal surgery should e performed painlessly, the entire area of the dentition scheduled for
surgery, the teeth as well as periodontal tissues should e anestheti4ed y proper anesthesia.?ocal infiltration and lock anesthesia are the methods of choice. After the initial administration
of local anesthesia, in@ect a drop of anesthetic solution directly into interdental papilla. *t makes
the gingiva firmer and easier to incise and has a hemostatic effect ecause of the vasoconstrictor
present in the solution. *n general, most periodontal surgical procedures are done under localanesthesia. /owever, in apprehensive patients or patients suffering from neurological disorders,
surgery is done under general anesthesia.
Tissue $anage&ent
Flap Preparation
)urgical flap is defined as the separation of a section of tissue from the surrounding tissues
e3cept at its ase. Flap can e full thickness or partial thickness.
Flap Design
Flap design should e ased on the principle of maintaining an optimal lood supply to the
tissue. +he recommended flap length 5height6 to ase ratio should e no greater than 9:8 (#ig. )*.
+he greater the ratio of the flap length to flap ase, the greater the vascular compromise at theflap margins.

Fig. 1: Flap height-to base ratio (Ratio should not exceed 2:1
Flap Reflection
A full thickness flap is elevated using a sharp periosteaelevator directed eneath the periosteum
keeping against the one. Papillae are reflected first, followed y the marginal gingiva, working
across the anterior#posterior e3tent of the incisions until the flap margin has een freed from theteeth or alveolar crest or oth. 1nce the flap margin has een completely released, the
periostealelevator is directed in oth hori4ontal and vertical plane until ade$uate access isachieved.
Flap Retraction
)urgical retractors are used to hold the flap ack from the teeth and one. Retraction should e
passive without any tension. "ontinuous flap retraction for long period is not advised. (hen theflap is retracted, the surgical field should e irrigated with the sterile saline to keep the tissues
moist, to reduce contamination and to improve visiility.
Flap Repositioning
)urgical flaps may e repositioned, apically positione coronally positioned or laterally
positioned. +he final flap location is determined y the goal of therapy and the specific
periodontal surgical techni$ue performed. +hus in general, tissue should e handled carefullywith minimum surgical trauma.
•se suction during surgery to avoid compression of tissues with dry sponge. "otton fiers of
dry sponge# gau4e could e left ehind and may e source of future irritation and infection.
•)terile saline solution should e used. •-o not low air into the surgical site as it may induce cervicofacial emphysema which can e
fatal.
•)lowspeed sharp surgical ur and ade$uate cooling should e used for one removal. Avoidundue drying of the one and do not heat the one aove =<B" otherwise it will cause necrosis of
one surface.
•Avoid heavy pressure against soft tissues#one.
Scaling and Root Planing
)caling and root planing in con@unction with periodont surgery is done on e3posed root surfaces
with the help of curettes.
%e&ostasis
)teps to minimi4e postsurgical leeding:
8.!efore appro3imation of flaps, all areas should e rinsed free of clots and the surgical site
should e checked again for leeding.9.Pressure should e applied to the flap to encourage minimal clot thickness.
>.Good closure with suturing discourages postsurgical hemorrhage.
=.-istal wedge and edentulous ridge sites should e well appro3imated carefully with attention ecause these areas are good source of postoperative leeding.
+ound Closure
+he various techni$ues of wound closure are sutures, skin clips#staples, skin tapes and woundadhesive CAutologous firin glue, firin fironectin sealing system 5+issucol6, "yanoacrylate,
0ussel adhesive proteinD.
+he various intraoral anchoring structures useful in securing movale tissues are:
i. Teeth: +hese teeth are easiest and most secure of all intraoral anchors.
ii. ound do!n tissue: Gingiva affi3ed to one via periosteum, is the second most reliale
anchor .

iii. "eriosteum.
iv. #oose connecti$e tissue: *t is the least secure anchoring structure in the mouth. "onnective
tissue in the vestiule and fatty tissue in the retromolar area are the e3amples of loose connectivetissue anchor source.
Suture and Suturing Techni,ues
)election of the type of suture material and needle is dependent on tissue type and thickness,location in them mouth, ease of handling, cost and the planned time of suture removal.

+he components of sutured knots are loop, knot and ears. Inot is composed of a numer of tight,
throws, each throw represents a weave of the two strands and ears that are the cut ends of the
suture. Inots should e tied as small as possile. "ompleted knots should e firm to reduceslippage. +ie knots on facial aspect for access in removal leaving 9 to > mm suture tail.

iii. Surgeon8s 6not '-: 8st tie is doule and 9nd tie is single in opposite direction.
iv. Surgeon8s 6not '-': 8st tie is doule and 9nd tie is also doule in opposite direction.
Principles of suture re&oval0
i. Areas should e swaed with hydrogen pero3ide for removal of encrusted necrotic deris,
lood and serum from suture.
ii. A sharp suture scissor should e used to cut the loops of suture, close to the epithelial surfaceas possile. *n this way, a minimal amount of portion of sutures that was e3posed to the outside
environment and has ecome laden with deris and acteria will e dragged through the tissue.
iii. A cotton plier is then used to remove the sutures. +he location of knots should e noted so
that they can e removed first, which will prevent unnecessary entrapment of the flap.Periodontal 'ressings
Periodontal dressings were first introduced in 8J9> when -r A( (ard advocated the rules anduse of packing material around the teeth following gingival surgery.
+his material was called (onder pack, which consisted of 4inc o3ide eugenol mi3ed with
alcohol, pine oil and asestos fiers.
Purpose
Periodontal dressings are used for the following reasons:
a. Protect the wound area from irritants such as hot# spicy food.
. &nhances patient comfort.c. /elps to maintain the position of repositioned soft tissues and act as a template to prevent
formation of e3cessive granulation tissue.
d. Also protects newly e3posed root surfaces from temperature changes, staili4es moile teethand protect sutures.
Properties
a. -ressing should e soft, ut with enough plasticityand fle3iility.
. -ressing should set within a reasonale time.
c. -ressing should have sufficient rigidity to prevent fracture and dislocation.
d. -ressing should have a smooth surface after settingto prevent irritation to the cheeks and lips.
e. -ressing should e dimensionally stale to prevent salivary leakage and accumulation of
pla$ue deris.f. -ressing should preferaly have actericidal properties to prevent e3cessive pla$ue formation.
g. -ressing should not induce allergic reactions.
h. -ressing should have an acceptale taste.i. -ressing must not detrimentally interfere with healing.

iii. "eriopac: *t is premi3ed Kn1 noneugenol dressing containing "a>5P1=69, Kn1, acrylate,
organic solvents, flavoring and coloring agents. (hen this material is e3posed to air or moisture,
it sets y the loss of organic solvents.
iv. 1ocopac: *t is a new formulated product for use as periodontal dressing. *t contains J7 gm ase and J7 gm catalyst. *t contains neither eugenol nor coumarin and causes no gingival
irritation, it retains its tough elastic $ualities throughout its life in the patients mouth, and does
not ecome rittle. *t adheres e3cellently to the teeth and promotes healing. 0i3ing time is aout97>7 seconds and its working time is appro3imately 878 minutes.
v. "erioputty: *t is a noneugenol dressing which contains methyl and propylparaens for their
effective acteriocidal and fungicide properties and en4ocaine as a topical anesthetic.
vi. arricaid $isible light cure periodontal dressing : +his single component of periodontal
dressing eliminates messy, time consuming mi3ing of paste. *t is availale in a syringe for the
direct application or dispensing on a mi3ing pad and placement intraorally. "uring of thematerial is then accomplished with a visile light curing unit to form a nonrittle, ut firm,

vii. 0ollagen dressings: An e3ample of collagen dressing is collocate. "ollagen dressing is in theform of collagen sponge which is a type * collagen derived from ovine Achilles tendon. *t is
completely resorale dressing that is used to cover and protect palatal graft sitesL the sponge is
appro3imately > mm thick and can e cut to fit the graft site. *t stops leeding and can asor >7=7 times its weight in fluid, without swelling.
viii. Methacrylate gel dressings: +hey have elastic consistency that is soft and resilient and will
flow under pressure. +hey adapt closely to the tissues and are very comfortale with wound site.
+he ma@or advantage of this material is its aility tocarry and release medicaments to the soft tissues.
i;. 0yanoacrylate: *n 8JH= tissue adhesives were introduced to dentistry. -r )2 !haskar
conceive the idea of their potential use in periodontics and conducted the ulk of the laoratory
and clinical research. +he asic formula of "yanoacrylate is "/M " 5"26 % "11R. +he utyland isoutyl formsare ideal as periodontal dressings. +he use of cyanoacrylate is an alternative to
suturing and as a surface adhesive and periodontal dressing. +his material has the uni$ue ailityto cement together
moist, living tissue surfaces. "yanoacrylate is either applied in drops or sprayed on the tissues.
+he material is much less ulky than other dressings.1ther advantages include lack of apparent side effects, easy adherence to living tissues,
immediate hemostasis, lack of evidence of systemic to3icity# sensitivity, precise placement of
flaps, decreased suturing time, ease of application and patient preference over ulky dressings. *t
is most useful in flap control in concave 4ones such as furcal area fluting. "yanoacrylate has een used for surface application onlyL adhesives that ecome trapped under soft tissue flap will
delay wound healing.
Antibacterial properties of pac6s: !acitracins,13ytetracycline 5+erramycin6, 2eomycin and 2itrofura3one have een tried, ut all may produce
hypersensitivity reactions. *ncorporation of tetracycline powder in "oe % Pak is generally
recommended, particularly when long and traumatic surgeries are performed.
Preparation and pplication of Periodontal Dressings
Kinc o3ide packs are mi3ed with eugenol or non % eugenol li$uids on a wa3 paper pad with a
wooden tongue depressor. +he powder is gradually incorporated with the li$uid until a thick
paste is formed. "oePak is prepared y mi3ing e$ual lengths of paste from tues containing theaccelerator and the ase until the resulting paste is of uniform color. +he pack is thenplaced in a
cup of water at room temperature, in 9> min the paste looses its tackiness and can e molded,
and it remains workale for 897 min. +he pack is then rolledinto two strips of appro3imately the length of the treated area. +he end of one strip is end into a
hook shape and fitted around the distal surface of the last tooth, approaching it from the distal
surface. +he remainder of the strip is rought forward along the facial surface tothe midline. +he second strip is applied from the lingual surface. *t is @oined to the pack at the
distal surface of the last tooth, and then rought forward along the gingival margin to the
midline. +he strips are @oined interpro3imally y applying gentle pressure on the facial and
lingual surfaces of the pack (#ig. )4*.

Postsurgical Care
-ay 8: Analgesics, cold packs, moist gau4e locally as needed, total avoidance of wounddisturance After day 8: Pain, swelling, leeding should diminish or disappear. !egin light
activity, warm packs as needed and chemical pla$ue control are recommended. After to 87
days: Remove dressing and sutures after < days: Professionally depla$ue supragingivally. !eginlight oral hygiene.
After = to H weekly: !iweekly visits for professional depla$ing and oral hygiene instructions.
+he dentogingival @unction should not e proed or instrumented for H to E weeks following
surgery. )oft toothrush should e used gently for the first few postoperative weeks. +he patientshould follow "harters method avoiding vigorous toothrushing.

*f postoperative complications occur, they should e managed y prompt and appropriate
treatment, which may include control of leeding, ade$uate analgesics or antiiotics.Co&plications associated =ith periodontal surgery are0
•/emorrhage •Postoperative pain
•*nfection
•)welling •Reaction to medications
•1ther potential risks include root sensitivity, flap sloughing, root resorption or ankylosis, some
loss of alveolar crest, flap perforation, ascess formation and irregular gingival contours.
%e&orrhage
Primary postoperative hemorrhage starts at the time of surgery. *ntermediate hemorrhage starts
soon after the surgery, after having stopped temporarily following surgery. *t is usually due to the
reakdown of an incomplete clot, such as is associated with loss of the vasoconstrictor effect ofanesthesia. )econdary hemorrhage starts from 9= hours to 87 days postoperatively.
Steps to control postsurgical bleeding0
8.First step to control leeding is to identify the source of leeding. )uction is done carefullyand local pressure with gau4e sponges is applied.
9.Oudicious in@ection of vasoconstrictor comined with continuous application of pressure
encourages clot
formation.>.Artificial clot may e induced y use of an o3idi4ed cellulose microfirillar collagen product.
=.&lectrocoagulation can e effective for capillary leeding sites and small arterioles.
.?arge arteriole leeding sites can e controlled y placing sutures in the soft tissue. Inot isdrawn tight to occlude vessel y compression from the surrounding tissue (#ig. )5*.
H.*f leeding is from intraosseous site then it can e controlled y one wa3 5eeswa3 and
salicylic acid6 which occlude ony canals.<.&3cessive leeding from interpro3imal and infraony lesions results from inade$uate
degranulation. Residual granulomatous tissue is a common source of hemorrhage, since it is
composed largely of capillaries.

Postoperative Pain
+he severity of postoperative pain varies depending on the patient threshold level, location,duration, e3tent of surgery and skill with which the soft and osseous tissue are handled during
surgery. Postoperative pain and discomfort for the patient can e minimi4ed y the surgical
handling of the soft and osseous tissues atraumatically. •+he one should e kept moist as dryness of one induces severe pain. +here should e
complete soft tissu e coverage of the one during suturing. +hus one e3posure should not e

frenum and palate.
•Patient should e instructed to avoid chewing from the operated site.

Gingival wounds heal much more rapidly with much less scar formation when compared to skin.
+he reason for this reduced scar formation are:a. Gingival firolasts unlike the firolasts of other connective tissue produce more 00P8>than 00P8. 00P8> has a road sustantivity and is capale of reak down#turnover of a
numer of e3tracellular matri3 proteins. 00P8 on the other hand has a iological activity that is
restricted to collagen *. +he greater presence of 00P8> in the wound area is thought to producea greater turnover and therey, prevent scar formation.
. +here is a greater presence of myofirolasts in thegingiva when compared to skin.
Firolasts can differentiate to form the more synthetic myofirolasts under the influence of+GF. +he presence of +GF in the wound area enhances the already greater presence of
myofirolasts therey leading to lesser wound contraction and scarring.
