Pericoronitis
Pericoronitis refers to inflammation around the crown of an unerupted tooth. It most commonly occurs with the mandibular third molar and can be acute, subacute, or chronic. Acute pericoronitis presents as a red, swollen, painful lesion that may cause fever and lymphadenitis. Treatment involves antibiotics and flushing the area for mild cases or flap removal for persistent symptoms to prevent recurrence. The decision to retain or extract the tooth depends on its stage of eruption, position, and likelihood of further eruption without complications.

Introduction to pericoronitis, its definition, and key topics in the presentation.
Pericoronitis defined as gingival inflammation related to an incompletely erupted tooth; common in mandibular third molars. Applies to acute, subacute, or chronic forms.
Commonly affected area is the mandibular third molar; includes symptoms like pain, foul taste, swelling, and potential systemic complications.
Localized complications include periodontal abscess; potential spread to areas causing dysphagia and involvement of multiple lymph nodes.
Treatment depends on inflammation severity; includes hygiene measures, antibiotics, and considerations for tooth extraction or retention to prevent recurrence.
References used for the presentation include textbooks and internet sources for clinical periodontology.

- 3. INTRODUCTION: The term pericoronitisrefers to inflammation of the gingiva in relation to the crown of an incompletely erupted tooth.
- 4. It occurs mostfrequently in the mandibular third molar area. It may be ACUTE SUBACUTE or CHRONIC
- 5. CLINICAL FEATURES: Thepartially erupted or impacted mandibular third molar is the most common site of pericoronitis. The space between the crown of the tooth & overlying gingival flap is an ideal area for the accumulation of food debris & bacterial growth.
- 6. Even in patientswith no clinical signs or symptoms, the gingival flap is often chronically inflamed & infected, with various degrees of ulceration along its inner surface.
- 7. Acute inflammatory involvementis a constant possibility. Acute pericoronitis is identified by various degrees of involvement of pericoronal flap & adjacent structures, as well as systemic complication. An influx of inflammatory fluid & cellular exudates results in increase in the bulk of the flap which interferes with complete closer of mouth.
- 8. The flap istraumatizes by contact with the opposing jaw, and the inflammatory involvement is aggravated. The clinical picture is that of markedly red, swollen, suppurating lesion that is tender, with radiating pains to ear, throat, & floor of mouth.
- 9. The patient isextremely uncomfortable because of pain, a foul taste, & an inability to close the jaw. Swelling of the cheek in the region of the angle of the jaw & lymphadenitis are common findings. The patient may also have toxic systemic complication such as fever, leukocytosis, & malaise.
- 10. COMPLICATION: The involvementmay become localized in the form of periodontal abscess. It may spread posteriorly into the oropharyngeal area & medially to the base of the tongue, making it difficult for the patient to swallow.
- 11. Depending on severity& extent of the infection, there is involvement of the submaxillary, posterior cervical, deep cervical, & retropharyngeal lymph nodes. Peritonsillar abscess formation, cellulitis, & Ludwig’s angina are infrequent but nevertheless potential sequelae of acute pericoronitis.
- 12. TREATMENT: The treatment ofpericoronitis depends on the severity of the inflammation, the advisability of retaining involved tooth. Persistent symptoms free pericoronal flaps should be removed as a preventive measures against subsequent acute involvement.
- 13. The treatment ofacute pericoronitis is consist of (i) Gently flushing the area with warm water to remove debris & exudate.
- 14. (ii) swabbing withantiseptic after elevating the flap gently from the tooth with a scalar.
- 15. Antibiotic can beprescribe in severe cases. After the acute symptoms have subsided, a determination is made as to whether the tooth is to be retained or extracted. This decision is governed by the likelihood of further eruption into a good functional position.
- 16. Following point maybe considered to decide whether the tooth is to be retained or not. (1)stage of eruption of tooth. If a possibility that the tooth will erupt further into a good functional position, it is advisable to retain the tooth. (2)impacted 3rd molar. If the tooth is impacted, it is better to extract the tooth as soon as the acute symptoms have subsided.
- 17. (3)position of tooth. Very often the tooth may be buccally placed with no attached gingiva on the buccal aspect. It may also be placed very much distally making it difficult to removed the gingival tissue adequately to create an environment which could be maintained plaque free.
- 18. Bone loss onthe distal surface of the second molar is a hazard after the extraction of partially or completely impacted third molar, & the problem is significantly greater if the third molars are extracted after the roots are formed Or in patients older than the early twenties. To reduced the risk of bone loss around second molar, should be extracted as early as possible in their development.
- 19. If it isdecided to retain the tooth, the pericoronal flap is removed using periodontal knives.
- 20. It is necessaryto removed the distal to the tooth as well as the flap on the occlusal surface.
- 21. Incising only theocclusal portion of the flap leaves a deep distal pocket, which invites recurrence of acute pericoronal involvement. After the tissue is removed, a periodontal pack is applied.
- 22. The pack maybe retained by bringing it forward along the facial & lingual surface into the interproximal space between the second & third molar. The pack is removed after one week.
- 23. CONCLUSION It is themost common type of pericoronal infection found mostly in mandibular third molar. Clinical features include red, swollen suppurating lesion along with the pain which may radiate to the surrounding tissues. Proper & immediate management is necessary to prevent its complication.
