Abstract(s)
INTRODUÇÃO: As parafunções do sistema estomatognático, consistem numa atividade
neuromuscular sem qualquer propósito funcional. Decorrente destes hábitos nocivos
podem surgir malformações a nível dentário, esquelético e tecidular, bem como evidências
clínicas que atestem a sua presença, como desgaste dentário e fissuras dentárias.
MATERIAIS E MÉTODOS: Foi realizado um estudo observacional transversal, clínico e
sem intervenção. A amostra foi constituída por 103 indivíduos, aos quais foi realizado um
exame clínico pelo investigador principal e aplicado um questionário de forma a verificar a
existência de sinais clínicos de atividade parafuncional nos dentes anteriores.
OBJETIVOS: Determinar a prevalência de hábitos parafuncionais, bem como detetar
sinais clínicos por eles causados, de modo a estabelecer uma eventual relação de causaefeito, dentro de uma população bem definida.
RESULTADOS: 16 dos 18 hábitos analisados demonstraram surgir com maior
prevalência em indivíduos do género feminino. Os hábitos mais prevalentes foram a
utilização de pastilha elástica e apoiar o queixo na mão. Os caninos na arcada superior e os
incisivos centrais na arcada inferior foram os dentes mais afetados por desgastes. Os
incisivos centrais superiores foram os dentes que apresentaram maior número de fissuras.
A maioria dos estudantes referiu um aumento da frequência dos seus hábitos
parafuncionais com a proximidade de avaliações teóricas e práticas e mencionou um
aumento ligeiro durante o confinamento social.
CONCLUSÃO: Determinou-se a existência de correlações entre as parafunções e os sinais
clínicos evidenciados pelos dentes anteriores, revelando-se estes achados bastante úteis no
diagnóstico precoce de parafunções.
INTRODUCTION: The parafunctions of the stomatognathic system consist of a neuromuscular activity without any functional purpose. As a result of these harmful habits, malformations may arise at the dental, skeletal and tissue level, as well as clinical evidence attesting to their presence, such as tooth wear and tooth fissures. MATERIALS AND METHODS: A cross-sectional, clinical and non-interventional observational study was carried out. The sample consisted of 103 individuals, to whom a clinical examination was performed by the main investigator and a questionnaire applied in order to verify the existence of clinical signs of parafunctional activity in the anterior teeth. OBJECTIVES: To determine the prevalence of parafunctional habits, as well as to detect clinical signs caused by them, in order to establish a possible cause-effect relationship, within a well-defined population. RESULTS: 16 of the 18 habits analyzed showed to appear with a higher prevalence in female individuals. The most prevalent habits were the use of chewing gum and resting the chin on the hand. Canines in the upper arch and central incisors in the lower arch were the teeth most affected by wear. The upper central incisors were the teeth with the greatest number of cracks. Most students reported an increase in the frequency of their parafunctional habits with the proximity of theoretical and practical assessments and mentioned a slight increase during social confinement. CONCLUSION: It was determined the existence of correlations between the parafunctions and the clinical signs evidenced by the anterior teeth, revealing these findings to be very useful in the early diagnosis of parafunctions.
