RESUMO
This study aimed to evaluate the effectiveness of photobiomodulation (PBM) therapy using 940-nm laser in patients undergoing orthognathic surgery. Twenty individuals were randomly distributed into laser (n = 10) and control (n = 10) groups. The PBM was conducted immediately after surgery, after 24 h, 48 h, and weekly for up to 4 weeks. All participants were evaluated for pain, edema, trismus and paresthesia. Data were compared by Fisher's and Mann-Whitney or chi-square tests (5%). The pain decreased from 24 h to 4 weeks, with the laser group reaching any pain after 3 weeks (p < 0.001). A significant difference was noticed for trismus on days 14 and 30 (p = 0.002; p = 0.019), without difference in paresthesia (p = 0.198). Edema was lower on the laser group compared to control, without a significant difference for most measurements. Data indicate that 940-nm PBM therapy decreased the occurrence of postoperative pain and significantly improved trismus.

The orthodontic-surgical treatment comprises different stages from diagnosis to final soft tissue accommodation, but there are no data regarding the patient's perception during these phases. This study aimed to investigate the impact of these stages on quality of life and self-esteem of patients with dentofacial deformity. Patients were divided into 4 groups according to the treatment stage: initial orthodontic pre-treatment (1), one week before surgery (2), three months after surgery (3), and after the removal of the orthodontic appliance (4) (n = 20 / group). They filled the following questionnaires: Oral Health Impact Profile (OHIP-14), Orthognathic Quality of Life Questionnaire (OQLQ) and Rosenberg Self-Esteem Scale (RSES). Data were evaluated by Kruskal-Wallis test. Differences among groups were noticed in all evaluated scales (p = 0.001 for all). No statistically significant differences between patients in groups 1 and 2 (OHIP, OQLQ, and RSES, p >0.05 for all), while patients at group 4 presented different scores in all questionnaires compared to 1, 2, and 3 (p < 0.05 for all), irrespective of the type of dentofacial deformity (p > 0.05). The results indicate that dental decompensation stage did not negatively affect patient's confidence and well-being. Despite the improvement noticed few months after the orthognathic surgery, the main impact on patient's quality of life and self-esteem was evidenced after the removal of the orthodontic appliance. We highlight the important role of counselling patients to discuss all the treatment stages to clarify patients' subjective expectations before any intervention is carried out.

Myiasis is the infestation of tissues and organs of animals and humans caused by the larvae of certain dipteran flies. It is more common in undeveloped and tropical countries and usually affects elderly patients, persons who are sick, and patients with mental illness. Oral myiasis is a rare pathologic condition and a risk to the patient's life because of its great destructive potential. Therefore, appropriate treatment is necessary. This article aimed to report a case of myiasis caused by Cochliomyia hominivorax in the palate of a patient with primary progressive aphasia, which was successfully treated through mechanical removal of larvae plus administration of ivermectin.
