RESUMEN
Introduction: The objective of this study was to evaluate the influence of the instrumentation kinematics on endodontic postoperative pain. Methods and Materials: PubMed, Scopus, Web of Science, Lilacs, Cochrane Library and the System for Information on Gray Literature in Europe were searched electronically without time or language limitations up to June 2020. Subsequently, data extraction, quality assessment and meta-analysis were conducted. The meta-analysis was performed using random-effects inverse-variance methods, and heterogeneity was tested using the I 2 index (P<0.05). Results: A total of 318 articles were successfully identified in the search. Sixteen studies were used in qualitative synthesis and fourteen used for quantitative synthesis. Meta-analysis showed that patients treated with reciprocating system had lower risk of pain 48 h after endodontic treatment (Risk ratio [RR]=1.04, 95% Confidence interval [CI]=1.01-1.06, P=0.003) (I2=0%), but the mean postoperative pain for the reciprocating system was greater 24 h post endodontic treatment (Standardized mean difference [SMD]=0.25, 95% CI=0.06 to 0.44, P=0.01) (I2=43%). Other time points presented similar rates of postoperative pain (P>0.05). The certainty of evidence ranges from very low to high. Conclusions: The rate of postoperative endodontic pain was low, and reciprocating systems evoked more pain within the 24 h interval. Overall, the incidence and level of postoperative pain did not vary between reciprocating and rotary systems. There is no consensus if there is a relationship between the kinematics (rotary and reciprocating) and the incidence of postoperative pain.
RESUMEN
Avaliou-se a qualidade de vida e as condições de higiene de próteses dentárias em idosos residentes em instituição de longa permanência, na Cidade de João Pessoa-PB. Metodologia: Foi aplicado o Geriatric Oral Health Assessment Index (GOHAI) para avaliar a qualidade de vida, em alta e moderada-baixa, incluindo perguntas sobre higienização de prótese dentária (n=38). Adicionalmente, as próteses de cada indivíduo foram recobertas por solução evidenciadora e fotografadas, para mensuração do biofilme. Os dados foram analisados inferencialmente a partir dos testes Qui-quadrado e Exato de Fisher (α=5%). A retenção do biofilme foi classificada, a partir das áreas coradas, em alta, média e baixa. Resultados: A média de idade da amostra foi de 81,8±7,7 anos, sendo 86,8% (n=33) do sexo feminino. Apenas 34,2% afirmaram ter recebido instrução sobre higienização e 86,8% referiram não remover a prótese em nenhum período do dia. A qualidade de vida não esteve associada ao tempo de uso da prótese, ou com o conhecimento em relação aos métodos químicos e mecânicos de higienização (p>0,05), mas se mostrou alta quando associada ao fato de não retirarem a prótese para dormir (p<0,05). Dentre as 26 próteses superiores analisadas, em 53,8% (n=14) observou-se baixa retenção; quanto às 13 próteses inferiores avaliadas, 53,8% (n=7) apresentaram retenção moderada. Conclusão: A alta qualidade de vida esteve associada ao fato do idoso não retirar a prótese para dormir. As próteses inferiores apresentaram maior retenção de biofilme em relação às próteses superiores. (AU)
Objetive: Quality of life and hygiene conditions of dental prostheses were evaluated in elderly residents of a long-term institution in the city of João Pessoa-PB. Methods: The Geriatric Oral Health Assessment Index (GOHAI) was used to evaluate high and moderate-low quality of life, including dental hygiene questions (n=38). In addition, the prostheses of each individual were covered by an evidentiary solution and photographed for biofilm measurement. Data were analyzed inferentially from Chi-square and Fisher's exact tests (α=5%). The retention of the biofilm was classified, from the stained areas, in high, medium and low. Results: The mean age of the sample was 81.8 years (±7.7), of which 86.8% (n=33) were female. Only 34.2% reported having received instruction on hygiene and 86.8% reported not removing the prosthesis at any time of the day. The quality of life was not associated with the time of use of the prosthesis, or with the knowledge regarding the chemical and mechanical methods of hygiene (p>0.05), but it was high when associated with the fact that they did not remove the prosthesis to sleep (p<0.05). Among the 26 upper prostheses analyzed in 53.8% (n=14), low retention was observed; regarding the 13 inferior prostheses evaluated, 53.8% (n=7) presented moderate retention. Conclusion: The high quality of life was associated with the fact that the elderly did not remove the prosthesis to sleep. The lower prostheses presented higher retention of biofilm in relation to the upper prostheses. (AU)
