Abstract To evaluate the impact of genetic polymorphisms in interleukins (IL1A rs17561, rs1304037; IL10 rs1800871; IL1RN rs9005), nitric oxide (NOS2 rs2779249, rs2897518) and suppressor of cytokine signaling (SOCS1 rs243327, rs33977706) on oral health-related quality of life (OHRQoL) of patients under-going root canal treatment (RCT). Methods: The sample consisted of 108 participants, presenting single-rooted teeth with asymptomatic periapical periodontitis. The impact of the OHRQoL was recorded using the Oral Health Impact Profile (OHIP-14) before, seven, and 30 days after RCT. Saliva samples were collected as a source of genomic DNA. Genetic polymorphisms were genotyped by Real-Time PCR using the Taqman method. Univariate and Multivariate analyses were used (p<0.05). Results: A significant difference was observed for the polymorphism rs2297518 in the NOS2 gene in functional limitation in the codominant (p=0.037) and recessive (p=0.001) models; in the physical pain (p<0.001 in both models); in psychological discomfort (p<0.001 in both models); in physical disability (p<0.001 in both models) and in psychological disability (p<0.001 in both models). Polymorphisms in the SOCS1 gene, in the recessive model, rs33977706 (p=0.045) and rs243327 (p=0.019), influenced the OHRQoL in the psychological discomfort domain. Conclusions: Polymorphisms in NOS2 and SOCS1 genes influenced the OHRQoL of patients undergoing RCT.

ABSTRACT Objective: To evaluate the impact of endodontic treatment with photobiomodulation on oral health-related quality of life (HRQoL). Material and Methods: Seventy participants with single-rooted teeth and a diagnosis of asymptomatic apical periodontitis were selected and randomized into two groups: control group (CG, n = 35), root canal treatment without additional treatment, and experimental group (EG, n = 35), root canal treatment associated with antimicrobial photodynamic therapy and low-level laser therapy. OHRQoL was assessed using the Oral Health Impact Profile Questionnaire (OHIP-14) at baseline and 7 and 30 days after treatment. Data were subjected to Wilcoxon, Mann-Whitney tests, and linear regression using the generalized estimating equation model, using the Statistical Package for Social Science software with a significance level of 5%. Results: No statistically significant differences were found between groups regarding sociodemographic and clinical characteristics (p>0.05). There was also no difference in the OHRQoL between the CG and EG (p>0.05). However, there was a statistical difference in OHIP-14 scores between baseline and the 7- and 30-day follow-up intervals in both groups for all domains (p<0.05). Conclusion: Root canal treatment, with or without photobiomodulation, significantly improved the OHRQoL of participants after 7 and 30 days of treatment. Objective healthrelated health related HRQoL.

ABSTRACT Objective: To compare postoperative pain, tenderness, edema, and medication use after foraminal enlargement in a single visit, using 2.5% sodium hypochlorite (NaOCl) and 2% chlorhexidine gel (CHX). Material and Methods: Seventy patients with single-rooted teeth with apical periodontitis were randomized into two groups according to the irrigation protocol: control (NaOCl - 35 patients) and case (CHX - 35 patients). Pain intensity was assessed using the visual analog scale (recorded every day for seven days, on the 14th and 30th days after treatment). Edema was assessed by two independent evaluators on the 2nd, 3rd, and 7th days after treatment using photographs. Data were analyzed using Chi-square, Fisher's Exact, and Mann-Whitney U tests in SPSS. Results: There was a statistically significant difference in postoperative pain and tenderness between the groups on the 2nd day (p<0.05). There was no difference between the groups for edema (p=1.00) and use of medication (p=0.77). Conclusion: Chlorhexidine resulted in more significant postoperative pain and tenderness after foraminal enlargement. Objective visit 25 2 5 2.5 NaOCl CHX. CHX .

Resumo Este estudo teve como objetivo avaliar a associação das variáveis idade, sexo, posição no arco, comprimento do dente, amplitude do canal radicular e tamanho da lesão periapical com a ocorrência de sinais e sintomas pós-operatórios (dor, dor ao toque e edema) e o uso de analgésicos após o tratamento endodôntico com alargamento foraminal em dentes uniradiculares com lesão periapical. Este estudo longitudinal prospectivo incluiu 105 pacientes que necessitavam de tratamento endodôntico em dentes uniradiculares superiores ou inferiores com lesão periapical. Após o tratamento do canal radicular em uma sessão, a intensidade da dor e a dor ao toque foram registradas diariamente por 7 dias e nos dias 14 e 30. O edema foi avaliado por dois avaliadores independentes dentro de 48 h, 72 h e 7 dias após o tratamento. Foram realizadas regressões ordinal e logística, e a significância estatística foi fixada em um valor de p < 0,05. Gênero feminino (beta = 1,02; p < 0.01), dentes inferiores (beta = 25,50; p < 0.01), amplitude média do canal radicular (beta = 0,93; p = 0,03) e edema (beta = 1,88; p < 0.01) foram associados ao aumento da dor e dor ao toque pós-operatória, enquanto o uso de analgésicos (beta = -1,82; p < 0.01) e o tempo em dias (beta = -0,23; p < 0.01) foram associados à diminuição desses sinais e sintomas. O edema foi considerado fator de risco para necessidade de analgésico (Odds Ratio [OR] = 61,46; p < 0.01). Fatores como sexo, posição do arco e amplitude do canal radicular foram associados aos sinais e sintomas pós-operatórios. O uso de analgésicos foi mais necessário no edema e foi associado à diminuição da dor.

Abstract This study aimed to evaluate the association of the variables age, gender, arch position, tooth length, root canal amplitude, and periapical lesion size with the occurrence of postoperative signs and symptoms (pain, tenderness, and edema) and the use of postoperative analgesics following root canal treatment with foraminal enlargement in single-rooted teeth with apical periodontitis. This prospective longitudinal study included 105 patients requiring root canal treatment of maxillary or mandibular single-rooted teeth with periapical lesion. After root canal treatment in a single session, pain intensity and tenderness were recorded daily for 7 days and on days 14 and 30. Edema was evaluated by two independent evaluators within 48 h, 72 h, and 7 days after treatment. Ordinal and logistic regressions were performed (p < 0.05). Female gender (beta = 1.02; p < 0.01), mandibular teeth (beta = 25.50; p < 0.01), medium root canal amplitude (beta = 0.93; p = 0.03), and edema (beta = 1.88; p < 0.01) were associated with increased postoperative pain and tenderness, while the use of analgesics (beta = -1.82; p < 0.01) and time in days (beta = -0.23; p < 0.01) were associated with a decrease in these signs and symptoms. Edema was considered a risk factor for analgesic requirement (Odds Ratio [OR] = 61.46; p < 0.01). Factors such as gender, arch position, and root canal amplitude were associated with postoperative signs and symptoms. The use of analgesics was more required in edema and was associated with decreased pain.

ABSTRACT INTRODUCTION: Diseases of the maxillary sinus have been associated with dental roots near the maxillary sinus that have undergone endodontic treatment. OBJECTIVE: To investigate the presence of filamentous fungi in patients with dental roots near the maxillary sinus who had apical periodontitis treated endodontically, and to alert practitioners that this could be a possible avenue of contamination of the sinus in patients who develop maxillary sinus infection. METHODS: Cross-sectional study in 60 palatal roots of the first maxillary molars near the maxillary sinus, that underwent endodontic treatment for apical periodontitis. After removal of the filling material, dentin shavings were collected and placed in test tubes containing Sabouraud dextrose agar and chloramphenicol. The phenotype was determined by macroscopic and microscopic examination of the colonies. For polymerase chain reaction, the primers ITS-5 and ITS-4 were used. The sequences obtained were compared with those deposited at GenBank using the Basic Local Alignment Search Tool program. RESULTS: Filamentous fungi were isolated from 6 of 60 canals (10%):Aspergillus niger (6.7%), Aspergillus versicolor (1.6%), and Aspergillus fumigatus(1.6%). CONCLUSION: Root canals near the maxillary sinus with endodontic treatment and apical periodontitis may exhibit positive cultures for filamentous fungi. Interested professionals should be alert, because these microorganisms have pathogenic characteristics that can cause disease of odontogenic origin in the maxillary sinus.
