RESUMO
BACKGROUND: Prime components of fixed orthodontic treatments decrease the self-cleansing ability of the tongue and the cheeks leading to an increase in production of bacterial plaque. Hence, the present study was undertaken for assessing the effect of fixed orthodontic treatment on gingival health. MATERIALS AND METHODS: A total of 120 patients who were scheduled orthodontic treatment were enrolled. Complete data records of all the patients were recorded. Intra- and extraoral radiographs were obtained and photographic records were noted in separate pro forma. Complete intraoral examination of all the patients was carried out for recording visible plaque, any inflammation (visible clinically), and gingival recession. Based on the assessment of gingival texture and capillary transparency, analysis of gingival biotype was done. Follow-up records were assessed. RESULTS: The mean visible plaque value before treatment and after treatment was found to be 3.11 and 5.81, respectively. The mean visible inflammation value before treatment and after treatment was found to be 2.89 and 15.43, respectively. The mean gingival recession score value before treatment and after treatment was found to be 0.19 and 0.383, respectively. A significant increase in the visible plaque value, visible inflammation value, and gingival recession score was observed posttreatment. While comparing the gingival biotype, it was seen that in both the maxillary and mandibular arches, there was an increase in the thick gingival biotype while there was a decrease in thin maxillary biotype. CONCLUSION: There is a significant increase in plaque accumulation, inflammation, and gingival recession following fixed orthodontic treatment. Hence, during the course of orthodontic treatment, regular oral prophylaxis should be done.
RESUMO
Aim. To compare and evaluate the static frictional resistance offered by the four different types of ligation methods in both dry and wet conditions and at different durations when immersed in artificial saliva. Material and Methods. Alastik Easy to Tie modules, Super Slick Mini Stix elastomeric modules, Power "O" modules, and 0.009(â³) Stainless Steel ligatures were used to compare the static friction using maxillary canine and premolar Preadjusted Edgewise brackets with 0.022(â³) × 0.028(â³) slot and 0.019(â³) × 0.025(â³) stainless steel wires. Results. The mean frictional resistance for Alastik modules was the lowest and that of Stainless Steel ligatures was found to be highest among the four groups compared and the difference among the four groups was statistically significant (P < 0.005). The mean static frictional resistance in all groups under dry conditions was lower than that under wet conditions. No statistical significant differences were found when the groups were compared at different time periods of immersion in artificial saliva. Conclusion. This study concludes that the Alastik modules showed the lowest mean static frictional forces compared to any other ligation method, though no significant difference was found for different time periods of immersion in the artificial saliva.
