RESUMO
BACKGROUND: Orthodontic treatment is a widely embraced intervention aimed at enhancing dental aesthetics and correcting malocclusions among adolescents. However, concerns persist regarding its potential impact on oral health, particularly on the development of dental caries. This study aimed to systematically investigate the relationship between orthodontic treatment and the incidence of new carious lesions among adolescents. METHODS: A prospective cohort design involving adolescents aged 12-18 years was employed. A total of 82 patients met the inclusion criteria. In addition, an age-matched control group of 82 participants who did not undergo orthodontic treatment was included. The study included both a treatment group undergoing orthodontic treatment (braces or aligners) and an age-matched control group that did not undergo any orthodontic intervention. Demographic characteristics, orthodontic treatment details, and oral hygiene practices were documented at baseline and throughout the study period. Dental examinations at six-month intervals post-treatment were conducted to track the incidence and progression of carious lesions. RESULTS: The demographic characteristics, baseline oral health status, orthodontic treatment details, and oral hygiene practices were comparable between the treatment and control groups. Post-orthodontic treatment assessment revealed a slightly higher incidence of new carious lesions in the treatment group (14.6%) than in the control group (9.8%), although this difference was not statistically significant (p = 0.15). Dental examinations at six-month intervals demonstrated a gradual increase in caries incidence over time in both groups, with no substantial disparities observed. CONCLUSIONS: This study provides a comprehensive examination of the relationship between orthodontic treatment and the incidence of new carious lesions among adolescents. While a trend towards higher caries incidence in the treatment group was observed, the difference was not statistically significant. These findings contribute to the existing body of knowledge and emphasize the need for ongoing research to guide clinical practice.
RESUMO
Background Third molar extraction is a routine oral surgical procedure that is often complicated by the development of a dry socket (alveolar osteitis). This prospective observational study aimed to investigate the prevalence of dry sockets and identify associated risk factors and causes, contributing to a comprehensive understanding of the postoperative outcomes of oral surgery. Methods This study employed a prospective observational design with a 12-month follow-up period. Participants aged 18-40 years scheduled for third molar extraction were included, whereas those with coagulopathies, pregnant or lactating women, patients with vitamin deficiencies, and individuals on medications affecting healing were excluded. Data collection involved comprehensive assessments at baseline, intraoperative details, and postoperative evaluations at 48 hours, one week, and two weeks. Statistical analyses included descriptive statistics, chi-square tests, t-tests, or Mann-Whitney U tests, and logistic regression for the risk factor analysis. Results A total of 238 participants with diverse demographic characteristics were enrolled in this study. The prevalence of dry sockets increased progressively from 20.6% at 48 hours to 41.2% at two weeks post-extraction. Smoking, poor oral hygiene, and surgical technique emerged as significant risk factors, with corresponding odds ratios of 6.41 (95% CI: 2.86-14.36, p < 0.001), 9.53 (95% CI: 2.12-42.84, p = 0.003), and 3.27 (95% CI: 2.08-5.15, p < 0.001), respectively. Pain intensity, measured using a Visual Analog Scale, gradually decreased from 48 hours to two weeks post-extraction. Conclusion This study provides valuable insights into the prevalence and risk factors associated with dry sockets following third molar extractions. Smoking, poor oral hygiene, and poor surgical techniques were identified as significant contributors, emphasizing the importance of preoperative counseling and targeted interventions.
RESUMO
The impact of inflammatory response on the biological characteristics of GMSCs has been the subject of studies, with conflicting findings. In order to more fully understand the effects of the localized inflammatory environment, the current study assessed the intensity and differentiating capacity of GMSCs derived from healthy periodontal tissues (H-GMSC) and GMSC derived from inflamed periodontal tissues (I-GMSC) tissues. Cells from every well were taken out and counted using a hemocytometer every three days for a total of 12 days. The findings of the cell proliferation assay, which involved quantifying the cells with the help of a hemocytometer at 0th day, 3rd day, 6th day, and 9th day, are shown. On day nine of culture, there was a considerable (P = 0.02) variation in the rate of multiplication between GMSCs from healthy gingival tissues and GMSCs from gingival tissues having inflammation. Additionally, I-GMSCs had a higher cell concentration on day twelve than that of H-GMSCs. However, there was no significant variance in PDT values comparing GMSCs from healthy gingival tissues and GMSCs from gingival tissues having inflammation (P > 0.05). The mean PDT findings of 66.7 h and 53.4 h have been documented for Healthy-GMSCs and Inflamed-GMSCs, respectively. In addition, compared to GMSCs from healthy gingival tissues, GMSCs from inflammatory tissues had decreased osteogenesis and increased adipogenic potential. To evaluate the efficacy of GMSCs derived from patients suffering periodontitis utilising human models for cell-based treatments, additional study is necessary.
