Mucogingival Surgery

High-yield revision notes with linked practice questions, written for dental students and candidates preparing for the ADC and other licensing examinations.

High-yield notes

Vestibular depth is measured from the gingival margin to the bottom of the vestibule.

The sulcular brushing technique requires the placement of the toothbrush at the gingival margin, which may not be possible with reduced vestibular depth.

"Gummy smile" may be corrected surgically by crown lengthening.

the mucogingival line in the incisor and canine areas is located approximately 3 mm apical to the crest of the alveolar bone on the radicular surfaces and 5 mm interdentally.

Techniques for gingival augmentation apical to the area of recession include free gingival auto graft, free connective tissue auto graft and the apically positioned flap.

A space between the graft and the underlying tissue is called as dead space

The disadvantage of the free gingival graft is color mismatch.

Periosteal separation technique is a vestibular extension technique where a fenestration is surgically created to create a scar that is firmly bound to the bone.

Subepithelial Connective Tissue Graft was given by Langer and involves the sandwiching of connective tissue from donor site.

Subpedicle (bilaminar) connective tissue graft is a variant of sub-epithelial connective tissue graft.

Creeping reattachment is the postoperative migration of the gingival marginal tissue in the coronal direction along portions of a previously cut root.

The reconstruction of the lost or reduced interdental papilla is the most difficult and unpredictable problem in esthetic periodontal therapy.

Ideally, the width/length ratio of a maxillary central incisor clinical crown should fall between 0.78 and 0.85.

Thus a central incisor with a width of 8.5 mm should have a length between 10 and 11 mm.

Blood supply is the most significant concern in mucogingival surgery

Cigarette smoking is a contraindication for root coverage techniques because the compromised gingival blood supply results in many failures.

Gingival Curettage

High-yield revision notes with linked practice questions, written for dental students and candidates preparing for the ADC and other licensing examinations.

High-yield notes

Inadvertent curettage is the curettage accomplished unintentionally during scaling and root planing.

ENAP is a definitive curettage procedure performed with a knife.

LANAP stands for Laser Assisted New Attachment procedure done by Nd:YAG laser.

Periodontal Surgery

Periodontics  ›  Surgery

General Principles of Periodontal Surgery

High-yield revision notes with linked practice questions, written for dental students and candidates preparing for the ADC and other licensing examinations.

High-yield notes

Patients is asked to quit or stop smoking for a minimum of 3 to 4 weeks after the surgical procedure.

The most common emergency is syncope, and the most common cause is fear and anxiety.

The most reliable means of providing painless surgery is the effective administration of local anesthesia.

Root planing falls under both phase I and phase II therapy.

Arteries vulnerable to damage during surgery/ incision are posterior mandible (lingual and inferior alveolar arteries) and the posterior, midpalatal regions (greater palatine arteries)

Minor areas of persistent bleeding from capillaries can be stopped by applying cold pressure to the site with moist gauze (soaked in sterile ice water) for several minutes.

Absorbable gelatin is absorbed in 4 to 6 weeks.

Oxidized cellulose is absorbed in 1 to 6 weeks.

Thrombin is intended for topical use only because it is applied as a liquid or powder. Thrombin should never be injected into tissues because it can cause serious, even fatal intravascular coagulation.

Fragments of calculus delay healing post surgically.

Tooth mobility is increased immediately after surgery, but it diminishes below the pretreatment level by the fourth week.

A common source of postoperative pain is overextension of the periodontal pack onto the soft tissue beyond the mucogingival junction or onto the frena.

Kirkland knife is kidney-shaped.

Electrosection, also known as electrotomy or acusection, is used for incisions, excisions, and tissue planing.

Electrosurgery is contraindicated for patients who have incompatible or poorly shielded cardiac pacemakers.

Larger and heavier curettes and sickles are often needed during surgery for the removal of granulation tissue, fibrous interdental tissues, and tenacious subgingival deposits. E.g. Prichard curette

Back-action chise (Rhodes chisel) is used with a pull motion, whereas the straight chisel (e.g., Wiedelstadt, Ochsenbein #1-2) is used with a push motion.

Restorative Prosthetic Considerations

Restorative & Prosthetic Considerations

High-yield revision notes with linked practice questions, written for dental students and candidates preparing for the ADC and other licensing examinations.

High-yield notes

Failure to control active periodontitis can result in acute exacerbations and bone loss during tooth movement.

At least 2 months of healing is recommended after soft tissue grafting procedures before initiating restorative dentistry.

The healthy gingival sulcus has shown an average depth of 0.69 mm

Greater than 3 mm of soft tissue between the bone and gingival margin, with adequate attached gingiva, allows crown lengthening by gingivectomy.

With less than 3 mm of soft tissue between the bone and gingival margin, or less-than-adequate attached gingiva, a flap procedure and osseous recontouring are required for crown lengthening.

The biologic, or attachment, width can be identified for the individual patient by probing to the bone level (referred to as "sounding to bone") and subtracting the sulcus depth from the resulting measurement.

High-yield notes

Lingual surfaces accumulate the least amount of plaque.

Diameters of common bristles range from

• 0.007 inch (0.2 mm) for soft brushes to
• 0.012 inch (0.3 mm) for medium brushes and
• 0.014 inch (0.4 mm) for hard brushes
