RESUMEN
INTRODUCTION: The physiological changes in mother-infant pairs during pregnancy increase the susceptibility to a series of infections, including those of the oral cavity. Therefore, the oral and systemic health of pregnant women is related to adverse pregnancy outcomes. OBJECTIVE: This cross-sectional study aimed to evaluate the systemic profile and periodontal status of women with a high-risk pregnancy. METHODS: Eighty-nine pregnant women at risk of preterm labor admitted to a hospital in southern Brazil were interviewed and received a periodontal examination. Data related to obstetric complications during pregnancy (pre-eclampsia, infections, medication use, and gestational diabetes) and systemic diseases were collected from medical records. The periodontal parameters of probing pocket depth, bleeding on probing, and clinical attachment level were evaluated. The data were tabulated, and statistical analysis was performed (p < 0.05). RESULTS: The mean age of participants was 24 years (SD = 5.62). Gingival bleeding was recorded in 91% of the participants. The prevalence of gingivitis was 31.46%, and periodontitis was 29.21%. No association between systemic conditions and periodontal disease was observed. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Periodontal inflammation was not associated with the systemic profile during pregnancy. However, women with high-risk pregnancies showed higher levels of gingival inflammation, emphasizing the importance of dental care during pregnancy.

Objectives: The association between maternal periodontal disease and adverse perinatal outcomes although extensively studied remains unclear. The aim of this study was to evaluate, by a case-control study, conducted in three hospitals the association between preterm birth and/or low birth weight (PTB/LBW) and clinical parameters of maternal periodontal disease. Material and methods: Postpartum women who gave birth to a newborn PTB/LBW (case group), and postpartum women who had babies at full term with normal weight (control group) were included, in 1:2 ratio. Data were collected through medical records, interview, and periodontal clinical parameters. Bivariate analysis was performed to assess the PTB/LBW proportion relative to independent variables and multiple logistic regression analysis to assess the association between adverse perinatal outcomes and independent variables. Results: The sample consisted of 148 cases and 296 controls. By the 148 postpartum women with PTB/LBW in case group, 126 (87.5%) had preterm birth, and 75 (50.7%) had PTB and LBW. The periodontal status and generalized periodontitis presence were not associated with any adverse pregnancy outcomes. Having made four or more prenatal visits was a protective factor for all outcomes. The history of previous PTB/LBW was a risk factor for new cases of PTB and PTB and/or LBW. The presence of systemic disease was associated with preterm and low birth weight (PTLBW). Preeclampsia and cesarean delivery were associated with all outcomes. Conclusions: The clinical parameters of maternal periodontitis were not considered as a risk factor for the studied adverse perinatal outcomes. Clinical relevance: The present study demonstrated no association between maternal periodontitis and PTB/LBW.

Objective. The aims of this study were to evaluate the periodontal health of pregnant women and to investigate the association of periodontal status with demographic and socioeconomic characteristics, as well as medical and dental history. Materials and Methods. A total of 311 pregnant women were interviewed to obtain sociodemographic data along with medical and dental histories. Clinical examinations were performed to record the presence of visible plaque, gingival bleeding, and caries activity. The periodontal condition was evaluated by Community Periodontal Index of Treatment Needs (CPITN) in one tooth of each sextant (16, 11, 26, 36, 31, and 46). Results. After the adjustment analysis, the presence of visible plaque remained the main determinant of gingival bleeding (OR = 2.91, CI = 1.91-4.48). First-trimester pregnancy status was also a predictor, with a lower prevalence of gingival bleeding observed in the second (OR = 0.87, CI = 0.77-0.99) and third (OR = 0.82, CI = 0.73-0.93) trimesters. Conclusion. In pregnant women, the presence of dental plaque and first-trimester pregnancy status were the main implicated factors predicting gingival bleeding.
RESUMEN
This study evaluated the influence of irrigation tip, root canal curvature and final apical diameter on periapical debris and irrigant extrusion during root canal instrumentation. After being classified as mildly or moderately curved, the mesiobuccal root canals of 90 human molars were instrumented. The teeth were allocated into three groups according to the used needle type: a flat open-end needle (Group 1), a side-vented needle (Group 2) or a double side-vented needle (Group 3). The amount of extruded material after instrumentation was calculated for each group. The differences in irrigant and debris extrusion between the experimental groups were analyzed with the Mann-Whitney U test. Irrigation tips and final instrument diameter differences were analyzed with the Kruskal-Wallis test. Multiple groups were compared using the Mann-Whitney U-test with a Bonferroni correction at α=0.05. The amount of extruded material from the double side-vented needle was significantly less than the open-ended flat needle (p=0.008), but there was no difference compared to the side-vented needle (p=0.929). The results showed no effect of root curvature and final apical diameter on the amount of irrigant and debris extrusion (p>0.05). The double side-vented needles generated the least material extrusion to the periapical tissues. Irrigation needle type had the greatest influence on periapical irrigant and debris extrusion and the double side-vented needles may be safely used during endodontic therapy.

Resumo Este estudo avaliou a influência do tipo de agulha de irrigação, curvatura do canal radicular e diâmetro apical final sobre a extrusão de detritos e solução irrigadora durante o preparo físico-químico do canal radicular. O canal mésio- vestibular de 90 molares foi instrumentado, após ser classificado como de curvatura leve ou moderada. Os dentes foram divididos de acordo com o tipo de agulha utilizada em 3 grupos: agulha de extremidade aberta (Grupo 1), agulha de extremidade fechada com abertura lateral (Grupo 2) ou agulha de extremidade fechada com dupla abertura lateral (Grupo 3). A quantidade de material extruído após a instrumentação foi calculada em cada grupo. As diferenças de extrusão de solução irrigadora e detritos entre os grupos experimentais foram analisados com o teste de Mann-Whitney. As diferenças entre o tipo de agulha de irrigação e o diâmetro apical final foram analisados com o teste de Kruskal-Wallis. Grupos múltiplos foram comparados usando o teste U de Mann-Whitney com correção de Bonferroni em α= 0,05. A quantidade de material extruído pela agulha de extremidade fechada com dupla abertura lateral foi significativamente menor do que a agulha de extremidade aberta (p = 0,008), porém não houve diferença em relação a agulha de extremidade fechada com abertura lateral (p = 0,929). Os resultados não indicaram relação entre a curvatura radicular e o diâmetro apical final sobre a quantidade de solução irrigante e detritos de extruídos (p> 0,05). O uso de agulhas com dupla abertura lateral resultaram em uma menor extrusão de material aos tecidos periapicais. O tipo de agulha de irrigação teve a maior influência sobre extrusão periapical de solução irrigadora e detritos. As agulhas de extremidade fechada com dupla abertura lateral podem ser utilizadas com segurança durante a terapia endodôntica.
