Resumo
O objetivo deste estudo cruzado foi avaliar 21 voluntários, submetidos a tratamento periodontal, quanto ao grau de ansiedade e sensação dolorosa, em duas sessões: 1) anestesia local (AL1) e raspagem periodontal (RP); 2) anestesia local (AL2) e raspagem periodontal associada a cirurgia periodontal (CP). A ansiedade foi avaliada pela Escala de Ansiedade Dental de Corah (EADC), aplicada antes das sessões, e a sensibilidade dolorosa através da Escala Analógica Visual (EAV), após o término das sessões. Os dados foram submetidos aos testes de Wilcoxon pareado e correlação de Spearman, com nível de significância de 5%. A maioria dos voluntários foi considerada "levemente ansiosa" nas duas sessões de atendimento. Não houve diferença significativa entre as sessões com relação à sensibilidade dolorosa à anestesia local e aos procedimentos periodontais, porém, quanto à sensibilidade dolorosa, houve diferença significativa entre anestesia local e procedimentos periodontais em cada sessão (EAV-AL1 e EAV-RP: p = 0,009; EAV-AL2 e EAV-CP: p = 0,008), sem correlação entre grau de ansiedade e sensibilidade dolorosa, exceto para EADC2-EAV-AL2 (r = 0,47; p = 0,03). Concluiu-se que o grau de ansiedade mantevese constante independente do procedimento e que a sensibilidade dolorosa à anestesia local foi superior à do procedimento periodontal, sugerindo que, controlada a dor do paciente por meio da anestesia local, os procedimentos subseqüentes tornam-se menos estressantes aos pacientes.

Abstract
This crossover study evaluated the level of anxiety and painful sensibility due to local anesthesia and periodontal therapy of 21 volunteers submitted to periodontal treatment, in two sessions: 1) Local anesthesia (LA1) and root scaling (RS); 2) Local anesthesia (LA2) and root scaling associated to periodontal surgery (PS). The anxiety was assessed by Corah Dental Anxiety Scale (CDAS) applied at the beginning of the sessions; pain sensibility was assessed by Visual Analogue Scale (VAS) in the end of the sessions. The data were analyzed by Spearman and Wilcoxon tests (α = 0.05). The majority of the volunteers was considered as “slightly anxious” in both sessions (p = 0.80). No statistically significant difference was observed between sessions in relation to pain sensibility to local anesthesia and periodontal treatment, however there was statistically significant difference in pain sensibility between local anesthesia and periodontal treatment in each session (VAS-LA1 and VAS-RS: p = 0.009; VAS-LA2 and VAS-PS: p = 0.008), with no correlation between anxiety and pain sensibility, except for CDAS2-VAS-LA2 (r = 0.47; p = 0.03). It can be concluded that the level of anxiety remained unchanged in the sessions with no correlation to the procedure and that pain sensibility to local anesthesia was higher than that associated to periodontal treatment, which suggests that, once the pain is controlled by local anesthesia, the treatment becomes less stressful to the patient.
