Laser therapy and light sources for labial lentigines in patients with Peutz-Jeghers syndrome.

Labial lentigines associated with Peutz-Jeghers syndrome are challenging and represent a cosmetic problem. Laser and intense-pulsed light sources (IPLS) can be used to treat these macules. However, there are few guidelines regarding the different types of protocols found in the literature. Thus, the purpose of this study was to review the pertinent literature on lasers and IPLS as therapy for labial lentigines in patients with Peutz-Jeghers syndrome. A detailed literature search was conducted in seven databases (Cochrane Library, Embase, Lilacs, PubMed, SciELO, Scopus and Web of Science) to November 2020. Data were extracted and analyzed from selected studies including study design, sample size, participants' skin color, age, and gender, parameters of the laser or IPLS used, interval and total sessions of laser application, results obtained, follow-up time and side effects. Thirteen out of 124 published studies met our eligibility criteria, covering 81 patients. Ten types of lasers and IPLS were used, and most of the sample (n = 57) was treated with Q-switch Alexandrite Laser (QSAL). The total number of sessions ranged from 1 to 12 and the interval between sessions ranged from 2 to 16 weeks. All studies have shown satisfactory results, with no further complications. The follow-up ranged from 2 to 97 months. Laser therapy and IPLS are effective in the treatment of lentigines associated with PJS. Although QSAL was used in 70.3% of the sample, different types of lasers showed comparable satisfactory results.

Photobiomodulation associated with sclerotherapy for treatment of hemangioma in the hard palate.

Vascular changes frequently involve the head and neck region and hemagioma is the most common. A 61-year-old female patient complained of severe pain in the hard palate. A purple lesion was found, measuring 1.5 cm, sensitive to palpation, and with a history of hemorrhage. The patient was fully edentulous and her upper denture compressed the lesion site. Diascopy confirmed the lesion's vascular origin. A diagnostic hypothesis of hemangioma was raised. In the first session, red laser light (660nm) was applied at 4 points around the lesion, with 0.5 J at each point, in order to obtain analgesia and trigger the repair process. The upper denture was also relined. In the second session, 2 mL of 5% monoethanolamine oleate was applied. After 14 days, total regression of the lesion was observed. Dental surgeons must be able to recognize, diagnose and treat vascular lesions in the oral cavity.

Fotobiomodulação associada à escleroterapia no tratamento de hemangioma em palato duro / Photobiomodulation associated with sclerotherapy for treatment of hemangioma in the hard palate

Resumo As alterações vasculares ocorrem frequentemente em região de cabeça e pescoço, sendo o hemangioma a mais comum. Paciente do sexo feminino, 61 anos, queixou-se de dor intensa em palato duro. Notou-se lesão arroxeada, de 1,5 cm, sensível à palpação e com histórico de hemorragia. A paciente era edêntula total, e a prótese total superior comprimia o local da lesão. Foi realizada a vitropressão, confirmando a origem vascular. A hipótese diagnóstica foi de hemangioma. Na primeira sessão, aplicou-se o laser vermelho (660 nm) em quatro pontos ao redor da lesão, sendo 0,5 J em cada ponto afim de se obter analgesia e iniciar o processo de reparo, além do reembasamento da prótese total superior. Na segunda sessão, foi feita aplicação de 2 mL de oleato de monoetanolamina 5%. Após 14 dias, observou-se regressão total da lesão. Os cirurgiões-dentistas devem estar aptos a reconhecer, diagnosticar e tratar as lesões vasculares em cavidade oral.

Aumento da hiperdensidade da cortical óssea línguo-basal após radioterapia em região de cabeça e pescoço: relato de caso / Hyperdensity of the lingual-basal bone cortex incresead after radiotherapy in the head and neck region: case report

Objetivo: relatar um caso de aumento da hiperdensidade da cortical óssea línguo-basal pós-radioterapia em região de cabeça e pescoço por meio de avaliação imaginológica. Relato de caso: paciente do sexo feminino, 80 anos, procurou tratamento odontológico com a finalidade de reabilitação oral com implantes dentários. Na anamnese, relatou histórico de carcinoma espinocelular em regiões distintas da cavidade oral. No exame clínico, notou-se que a paciente era edêntula total e foi solicitado um exame de tomografia computadorizada de feixe cônico. Foi observado, na região anterior inferior, aumento da hiperdensidade da cortical óssea línguo-basal, com osso compacto mais espesso, achado incomum na literatura após radioterapia. Considerações finais: os efeitos da radioterapia em mandíbula estão relatados na literatura. No caso clínico em questão, detectou-se uma alteração pouco notada em pacientes submetidos à radioterapia, fazendo surgir novos questionamentos, sendo eles sobre o diagnóstico dessa modificação na estrutura óssea e suas repercussões.

Objective: to report a case of increased hyperdensity of the lingual-basal bone cortex after radiotherapy in the head and neck region by means of imaging evaluation. Case report: female patient, 80 years old, sought dental treatment for the purpose of oral rehabilitation with dental implants. In the anamnesis, she reported a history of squamous cell carcinoma in different regions of the oral cavity. Upon clinical examination, it was noted that the patient was total edentulous and a cone beam computed tomography examination was requested. An increase in the hyperdensity of the lingual-basal bone cortex was observed in the lower anterior region, with thicker compact bone, an unusual finding in the literature after radiotherapy. Final considerations: the effects of radiotherapy on the mandible are reported in the literature. In the clinical case in question, a little-noticed change was detected in patients undergoing radiotherapy, leading to new questions, concerning the diagnosis of this change in bone structure and its repercussions.(AU)

Reabsorção radicular apical: relato de caso clínico / Apical root resorption: clinical case report

A severidade da reabsorção apical está associada a vários fatores do tratamento ortodôntico como: a duração do tratamento, magnitude das forças aplicadas e o tipo de aparelho ortodôntico.Objetivo: demonstrar, por meio de um relato de um caso clínico, o processo de reabsorção apical após tratamento ortodôntico.Conclusões: foi possível observar que a paciente, mesmo sendo jovem, apresentou arredondamento e alto grau de reabsorção radicular principalmente nos dentes 25 ao 15. A intensidade da força, associada ao tempo, colaborou com a reabsorção. O grau de reabsorção radicular pode estar relacionado ao uso de aparelho ortodôntico fixo por tempo prolongado...

The severity of the apical root resorption is associated with a several factors of the orthodontic treatment as the duration of the treatment, magnitude of the applied forces and the type of used orthodontic equipment.Aim: demonstrate with a clinical case the apical root process after an orthodontic treatment.Conclusions: in this clinical case, it was observed that the patient, even being young, presented rounding and high degree of root resorption mainly in teeth 25 to the 15. The intensity of the force, associated with time, had collaborated with the resorption. The degree of root resorption can be related to the use of fixed orthodontic for a long time...
