RESUMEN
Abstract The main purpose of this study was to answer the question: "Can radiotherapy cause changes in the dental pulp condition of patients treated with irradiation in the head and neck region?" Clinical observational studies in adults with head and neck cancer undergoing treatment with ionizing radiation, longitudinal or cross-sectional follow-up to measure oxygen saturation (SpO2), and/or pulp sensitivity test to cold stimulation, were considered eligible. A systematic literature search was performed in six different databases, including the gray literature, and in article references. Two independent evaluators selected the studies, extracted the data, recorded the data on electronic spreadsheets, and then evaluated the methodological quality using the Checklist for Quasi-Experimental Studies tool devised by JBI. The data were assessed qualitatively using the Synthesis Without Metanalysis (SWiM) guidelines. After removing the duplicate articles, carefully analyzing the titles and abstracts, and reading the papers in full, seven studies were included. Four of the studies evaluated applied the cold sensitivity test, two associated pulse oximetry and cold sensitivity, and only one used just pulse oximetry. Evaluation using the cold sensitivity test and pulse oximetry in the initial periods before radiotherapy showed a decrease in the sensitive response and in SpO2 levels during a maximum period of 1 year. However, analyses thereafter indicated a normal response in both tests from 5 to 6 years after the end of radiotherapy treatment. Radiotherapy causes changes in pulp behavior patterns in the short term; however, recovery and return to average values occurs after long periods.
RESUMEN
O Ceratocisto Odontogênico (CO) é um cisto de desenvolvimento odontogênico relativamente prevalente na população e com caráter eventual de agressividade com crescimento ântero- -posterior insidioso. Trata-se de uma lesão cuja apresentação é extremamente diversa com relação à faixa etária, gênero e aspectos imaginológicos mais prevalentes. O presente trabalho relata o caso de um garoto de 11 anos de idade, portador de uma extensa lesão mandibular, envolvendo desde o dente 33 até o 46, cuja microscopia foi compatível com CO. O artigo aborda toda a conduta propedêutica conduzida pela equipe a nível ambulatorial, bem como a interdisciplinaridade com a ortodontia, possibilitando um desfecho almejado e satisfatório do caso.
Keratocyst Odontogenic (KO) is a cyst of odontogenic development relatively prevalent in the population and with an eventual aggressive character with insidious antero-posterior growth. It is a lesion whose presentation is extremely diverse in relation to age, gender and most prevalent imaging aspects. This paper reports the case of an 11 - year - old boy with an extensive mandibular lesion, evolving from tooth 33 to 46, whose microscopy was compatible with KO. The article deals with all the propaedeutic conduct conducted by the team at the outpatient level, as well as the interdisciplinarity with orthodontics, enabling a desired and satisfactory outcome of the case.
