RESUMO
Aims: Oral nerve injuries are the primary cause of paresthesia in the head and neck regions. To report the managing of a combined protocol involving extraoral and intraoral photobiomodulation (PBM) therapy for lingual nerve paresthesia. Case report: A 38-year-old female patient underwent 25 PBM sessions using laser with dual wavelength infrared (810nm + 980 nm). The extraoral application included 6 seconds and 6J per point. per point, 1W, 4.91 cm², 1.2 J/cm. The intraoral protocol with 0.3W of power, a spot size of 0.38 cm², 15.78 J/cm² of energy density, 6J of energy per point, for 20 seconds. Results: Assessment of neurosensitivity on the dorsum of the tongue was a 75% improvement. On the lateral tongue improved to 50%. In the floor of the mouth, PBM demonstrated a 25% improvement. Conclusion: PBM is an important treatment option in the case of lingual nerve paresthesia. The use of PBM should be considered as a feasible, non-invasive treatment approach.
RESUMO
Trauma and pulpal infections in primary dentition are part of the routine of the pediatric dentist. Common consequences in these cases are alterations in dental color, compromising patient's esthetics and his interaction in social environment. Bleaching intends to preserve dental structure already weakened and to show immediate esthetic results. This clinical case shows a bleaching technique in devitalized primary teeth using bleaching agent with 35% hydrogen peroxide activated by photo polymerizer. This technique is simple and shows immediate satisfactory results.
