ABSTRACT

ABSTRACT Introduction: Bruxism is defined as a repetitive activity of masticatory muscles, characterized by the clenching or grinding of the teeth, which can occur during wakefulness (awake bruxism) or during sleep (sleep bruxism). Objectives: The objectives of the present study were to determine the prevalence of awake bruxism and its associated factors. Methods: Sample was composed by 50 participants of both genders, aged between 18 and 60 years, submitted to a clinical examination - to observe the presence of tooth wear, marks on the mucosa, or masseter muscles hypertrophy - and self-applied questionnaires, which evaluated the presence of TMD signs and symptoms, oral behaviors, lifestyles, anxiety level and sleep quality. Results: The prevalence of awake bruxism was 48%. Its presence was statistically and significantly associated with the presence of signs and symptoms of TMD (p=0.002), poor sleep quality (p=0.032), buccal mucosa indentations (p<0.001) and tongue (p=0.011). Age, gender, social characteristics, habits (such as coffee ingestion, smoking, alcoholism and physical activity) and tooth wear were variables that had no significant association with awake bruxism. Conclusions: It was concluded that awake bruxism shows a high prevalence and a positive association with signs and symptoms of TMD and worst sleep quality. In addition, awake bruxism is more likely to occur in individuals who have buccal mucosa indentation and who present high rates of oral habits and oral behaviors.


RESUMO Introdução: O bruxismo é definido como a atividade repetitiva dos músculos mastigatórios, e pode ocorrer durante o período acordado (bruxismo em vigília) ou durante o sono (bruxismo do sono). Objetivo: O presente estudo teve como objetivo avaliar a prevalência de bruxismo em vigília e seus fatores associados. Métodos: A amostra foi composta por 50 participantes, de ambos os sexos, com idades de 18 a 60 anos, avaliados por meio de minucioso exame clínico - para observar se havia presença de sinais como desgaste dentário, indentações na mucosa, hipertrofia do músculo masseter - e de questionários autoaplicáveis que visaram avaliar a presença de sinais e sintomas de disfunção temporomandibular (DTM), os comportamentos orais e hábitos de vida, o nível de ansiedade e a qualidade de sono dos participantes. Resultados: A prevalência de bruxismo em vigília foi de 48%. Sua presença foi associada, estatística e significativamente, com a presença de sinais e sintomas de DTM (p=0,002), má qualidade do sono (p=0,032), e indentações na mucosa jugal (p<0,001) e língua (p=0,011). Por outro lado, a idade, sexo, características sociais, hábitos (como ingestão de café, fumo, álcool e prática de atividade física), e o desgaste dentário foram variáveis que não tiveram associação com o bruxismo em vigília. Conclusão: Diante disso, conclui-se que o bruxismo em vigília possui uma prevalência significativa e uma associação positiva com DTM e qualidade do sono. Além disso, o bruxismo em vigília apresenta maior probabilidade de acontecer em indivíduos com indentação de mucosa jugal e com alta prevalência de hábitos e comportamentos orais.

ABSTRACT

ABSTRACT Low pressure Pain Threshold (PPT) is considered a risk factor for Temporomandibular Disorders (TMD) and is influenced by psychological variables. Objectives To correlate deep pain sensitivity of masticatory muscles with prosthetic factors and Oral-Health-Related Quality of Life (OHRQoL) in completely edentulous subjects. Material and Methods A total of 29 complete denture wearers were recruited. The variables were: a) Pressure Pain Threshold (PPT) of the masseter and temporalis; b) retention, stability, and tooth wear of dentures; c) Vertical Dimension of Occlusion (VDO); d) Oral Health Impact Profile (OHIP) adapted to orofacial pain. The Kolmogorov-Smirnov test, the Pearson Product-Moment correlation coefficient, the Spearman Rank correlation coefficient, the Point-Biserial correlation coefficient, and the Bonferroni correction (α=1%) were applied to the data. Results The mean age (standard deviation) of the participants was of 70.1 years (9.5) and 82% of them were females. There were no significant correlations with prosthetic factors, but significant negative correlations were found between the OHIP and the PPT of the anterior temporalis (r=-0.50, 95% CI-0.73 to 0.17, p=0.005). Discussion The deep pain sensitivity of masticatory muscles in complete dentures wearers is associated with OHRQoL, but not with prosthetic factors.

ABSTRACT

ABSTRACTBACKGROUND AND OBJECTIVES:Trigeminal neuralgia is a debilitating painful condition found in some patients. It is classified as neuropathic episodic pain, reported as “electric shock”, “burning” and/or “tingling”. This study aimed at evaluating the impact of trigeminal neuralgia on quality of life and its association with pain duration.METHODS:Participated in the study 20 patients above 40 years of age, who were divided in two groups. Group I was was comprised of 10 trigeminal neuralgia patients and group II of healthy painless patients. All patients have filled a visual analog scale about pain severity and the Oral Health Impact Profile questionnaire about quality of life. Group I patients were also asked about time of pain onset. Data were recorded and submitted to statistical analysis (Spearman correlation and Mann-Whitney tests).RESULTS:Trigeminal neuralgia significantly and negatively impacts quality of life (p≤0.01). However, neither pain intensity nor pain duration seem to be associated with this result.CONCLUSION:Trigeminal neuralgia negatively impacts quality of life regardless of pain intensity.


RESUMOJUSTIFICATIVA E OBJETIVOS:A neuralgia trigeminal é uma condição dolorosa debilitante encontrada em alguns pacientes. É classificada como uma dor neuropática episódica, reportada como “choque elétrico”, “queimação” e/ou “formigamento”. O objetivo deste estudo foi avaliar o impacto da neuralgia trigeminal na qualidade de vida e sua associação com o tempo de dor.MÉTODOS:Foram avaliados 20 pacientes, acima de 40 anos, divididos em 2 grupos. O grupo I foi formado por 10 pacientes com neuralgia trigeminal e o grupo II por 10 pacientes saudáveis, sem dor. Todos os pacientes preencheram uma escala analógica visual sobre a gravidade da dor e o questionário Oral Health Impact Profile sobre qualidade de vida. Os pacientes do grupo I também foram questionados sobre o tempo de início da dor. Os dados foram registrados e submetidos a análise estatística (testes de correlação de Spearman e de Mann-Whitney).RESULTADOS:A presença da neuralgia trigeminal tem impacto significativo e negativo na qualidade de vida (p≤0,01). No entanto, nem a intensidade da dor, nem o tempo de dor parecem estar associados a esse resultado.CONCLUSÃO:A neuralgia trigeminal exerce um impacto negativo na qualidade de vida, não importando a intensidade da dor.
