8. Pediatric dentistry
PBM in pediatric dentistry
Pediatric PBM is not adult PBM with a smaller patient. Cooperation, consent, communication and eye protection change the entire delivery plan.
Traumatic mucosal lesions, postoperative comfort, healing support in cooperative children.
Same biological targets, applied to thin, rapidly healing tissue in a patient whose cooperation determines feasible exposure time.
Tissue and anatomical targets
- • Labial and buccal mucosa
- • Traumatic ulcers
- • Post-extraction soft tissue
- • Gingiva
Clinical objectives
- • Comfort
- • Healing support of traumatic lesions
- • Reduced procedural distress
Dosimetric reasoning
- • Design the protocol around achievable exposure time, then state the resulting fluence honestly.
- • Prefer fewer, well-placed points.
Technique
- • Tell–show–do before application.
- • Non-contact over ulcerated tissue.
- • Parent present and informed.
Limitations
- • Uncooperative child = unreliable dose delivery.
- • Total planned time may exceed tolerance; plan fewer points.
- • Parental consent and child assent are mandatory.
Safety
- • Age-appropriate eye protection for child, parent and operator.
- • Explain the device in child-appropriate language before switching it on.
- • Never restrain to complete an elective adjunct.
Common errors
- • Copying an adult point map the child cannot tolerate.
- • Recording planned rather than delivered dose.
Clinical pearls
- • Delivered dose is the only dose that exists. Record what actually happened.
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
A 5-year-old tolerates only 30 s total. What should you do?
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).
