兽医学中的牙龈炎和激光牙周护理

Abstract

Oral diseases affect more than 70% of adult dogs and cats. Gingivitis is reversible if treated early. Conventional treatment involves scaling and root planing, but gingivitis laser treatment 和 laser treatment for gingivitis now play a critical role in both dentistry and 兽医激光疗法.

Section 1: Gingivitis Pathophysiology

• Caused by bacterial biofilm and plaque.
• Early stage symptoms: gum redness, swelling, halitosis, bleeding.
• Progression leads to periodontitis with irreversible bone loss.

---

Section 2: Principles of Gingivitis Laser Treatment

• Selective photothermal ablation of inflamed gingival tissue.
• Bactericidal effect on Porphyromonas gingivalis and other anaerobes.
• Stimulation of fibroblast activity for gum tissue repair.

Laser Options:

• Diode lasers: 810–980 nm.
• Nd:YAG: deeper penetration, strong bactericidal effect.
• CO₂: efficient for superficial ablation.

Section 3: Veterinary Laser Therapy in Dentistry

兽医激光疗法 extends beyond musculoskeletal use. In dentistry it enables:

• Gingivitis treatment.
• Periodontal pocket sterilization.
• Extraction site healing.
• Pain reduction in oral surgery.

Section 4: Case Report — Gingivitis Laser Treatment in a Dog

病人 Beagle, 6 years old, 12 kg.
诊断 Severe gingivitis with early periodontal pockets.
临床结果 Intense gum bleeding, halitosis, gingival swelling.

治疗方案：

• Sedation applied.
• Diode laser (980 nm, 1.5 W continuous mode) targeted at gingival margins.
• Plaque removal via scaling followed by laser disinfection of periodontal pockets.
• Total chair time: 30 minutes.

结果

• Minimal intraoperative bleeding.
• Healing observed within 5 days.
• At 3-month follow-up, no bleeding during brushing and periodontal pocket depth reduced.

结论 This case confirms that laser treatment for gingivitis is an effective adjunct to scaling, ensuring longer remission periods in veterinary dental care.
