5. Oral surgery
PBM in oral surgery
Postoperative pain, oedema and soft-tissue healing are the clearest clinical objectives — provided the surgical cause of the symptom has been excluded.
Adjunctive support after extraction or surgical procedures, and in selected soft-tissue trauma.
Inflammatory modulation and analgesic effect during the early inflammatory and proliferative phases of wound healing.
Tissue and anatomical targets
- • Extraction socket margins
- • Flap and suture line
- • Buccal/extraoral projection of the surgical field
- • Masticatory muscles when trismus is present
Clinical objectives
- • Postoperative pain modulation
- • Oedema modulation
- • Soft-tissue healing support
- • Recovery comfort
Dosimetric reasoning
- • Combine intraoral peri-socket points with an extraoral projection when the target is deeper.
- • Account for tissue thickness on the extraoral path.
- • Plan sessions across the early postoperative window, not a single application.
Technique
- • Non-contact intraorally over a fresh clot; contact extraorally.
- • Avoid pressure over the clot.
- • Symmetrical point mapping for reproducibility.
Limitations
- • Does not drain, debride or decompress.
- • Does not treat alveolar osteitis etiology.
- • Cannot replace analgesic or antimicrobial management where indicated.
Common errors
- • Applying PBM to escalating pain with swelling and fever instead of diagnosing infection.
- • Disturbing the clot with a contact tip.
Clinical pearls
- • Increasing pain after day three is a diagnostic signal, not a dosing signal.
Indications and evidence level
Biphasic dose-response, irradiance and light–tissue interaction were established there. Now apply them to this specialty's tissue thickness, vascularity and inflammatory state.
State the diagnosis and clinical objective before selecting a single parameter, and record the evidence level supporting what you tell the patient.
Eye protection for patient, operator and assistant. PBM does not remove the need for diagnosis, clinical judgment or medical coordination.
Knowledge checkpoint
Day 4 after extraction: increasing pain, purulent discharge, localised swelling. First action?
Chapter summary
- • The biological principles are unchanged; the target, objective and strategy change.
- • Etiological treatment first; PBM as adjunct where justified.
- • Only claim what the evidence level supports.
- • Systematic reviews and meta-analyses on PBM in dentistry — to be curated by the academic team.
- • International PBM/laser safety guidance applicable in the institution's jurisdiction.
- • Institutional clinical protocol documentation (where authorised).
