The aims of this literature review are: to depict the main oral diseases that are related to pregnancy; to clarify some of the possible systemic mechanisms that are associated with these changes; and to address issues about oral care during pregnancy. A woman's organs undergo various physiological, neurological, and hormonal changes during pregnancy. Such changes occur gradually and are essential for the development of the fetus, providing what is needed for tissue formation and establishment of reserves for uterine and fetal life. In turn, the oral cavity shows some events during this period. Among the changes most frequently cited in the literature are pyogenic granuloma, gingivitis, and periodontitis. The inflammation of the periodontal tissues due to the formation of the biofilm increases dramatically in size and severity during the course of a normal pregnancy, even without changes in the amount of biofilm present. In addition, a decrease in salivary pH is observed in pregnant women and may lead to an increased incidence of dental caries in this period.
This retrospective study evaluated the clinical outcome of 139 teeth restored with carbon fiber posts after 3 years of placement, considering the amount of remaining dentin as the main variable. Eighty-one patients received the fiber posts within a period of 16 months and were recalled after 3 years. The tooth type, amount of remaining dentin, and prosthetic crown material were evaluated. No loss of post or core retention was detected after 3 years of follow up. During the observed time, root or post fracture and secondary caries were not recorded. Only one failure concerning endodontic treatment was detected. The amount of remaining dentin was not an important characteristic in the restorative failure of endodontically treated teeth restored with carbon fiber posts within 3 years.
Introduction:A significant number of endodontically treated teeth restored with posts have associated periapical lesions, and several authors have discussed the probable causes of the development of these. Attention has been focused on restorative procedures performed after endodontic treatment and their association with the prognosis of endodontic therapy because a number of root-filled teeth will require post- and core-retained restorations.Purpose:The purpose of this study was to evaluate, by examination of periapical radiographs, whether the placement of intra-radicular posts in endodontically treated teeth may act as a risk factor for development of periapical lesions.Material and Methods:This case-control study analyzed periapical radiographs of 72 endodontically treated teeth with coronal restorations. All radiographs were obtained from a single private practice. Specimens were assigned to 2 groups: Group 1 (control) was composed of teeth without periapical lesions and Group 2 (case) was composed of teeth with periapical lesions. The number of teeth with and without posts in each group was recorded. Three calibrated examiners analyzed the radiographs visually under X4 magnification.Results:In Group 1, 28 (65.1%) out of 43 teeth were restored with posts. In Group 2, 24 (82.8%) out of 29 teeth had intra-radicular posts. The interpretation of chi-square test showed that these percentages were not significantly different (x2=2.687; p=0.101). Odds ratio was 2.571 (0.8158.118), which indicates that there was no statistically significant association between periapical lesions and posts.Conclusion:Intra-radicular posts placed in endodontically treated teeth were not a significant risk factor for development of periapical lesions in the practice where the cohort of patients was treated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
