Periodontal and microbiological evaluation in cleft lip/palate patients undergoing orthodontic treatment: A cross-sectional study.

BACKGROUND: The present cross-sectional study was undertaken to evaluate the periodontal and microbiological parameters in patients with surgically repaired unilateral cleft lip and palate (UCLP) undergoing orthodontic correction in comparison to patients without any cleft or orthodontic treatment. METHODS: A total of 120 patients, out of initial 148 patients, between the age group 6 and 18 years were enrolled and divided into four groups with 30 patients each: non-cleft patients without orthodontic treatment in Group 1, non-cleft patients undergoing fixed orthodontic treatment in Group 2, patients with UCLP without any orthodontic treatment in Group 3, and patients with UCLP undergoing fixed orthodontic treatment in Group 4. Periodontal parameters including plaque index (PI), gingival index (GI), gingival bleeding index (GBI), community periodontal index of treatment needs (CPITN) index, pocket probing depth (PD), and tooth mobility were measured in all the groups. The subgingival plaque samples of all the patients were subjected to microbial evaluation using matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF-MS) for clinical diagnosis. RESULTS: The periodontal parameters were significantly raised in Group 4, followed by Group 3 and Group 2 in comparison to Group 1 (p < 0.01), thereby suggesting poor periodontal health in patients with UCLP undergoing orthodontic treatment. Statistically significant differences (p < 0.01) in counts of micro-organisms among the groups were observed for P. gingivalis, P. intermedia, Veillonella, and Capnocytophaga, with the highest proportions in Group 4, indicating a deteriorating oral health in these patients. CONCLUSION: Poor periodontal and microbial health in patients with UCLP undergoing orthodontic treatment indicates a need for reinforcement of oral hygiene practices among these patients.

Cytokine levels in gingival crevicular fluid samples of patients wearing clear aligners.

OBJECTIVE: The aim of this study was to assess & compare the changes in cytokine levels in GCF samples of patients wearing clear aligners. METHODS: GCF samples of 10 patients undergoing orthodontic treatment, for correction of lower anterior crowding with clear aligners, were collected on day 0, 1, 3, 7 and 21 using periopaper strips. The upper arch was taken as the control site. The samples collected were further analyzed using commercially available ELISA based kits. RESULTS: The mean levels of IL-1ß at day 0, 1, 3, 7 and 21 were compared between experimental and control sites using unpaired t-test and it was found that the levels of IL-1ß were significantly elevated on experimental site in comparison to control site. CONCLUSION: It was concluded from the study that elevation in levels of IL-1ß as a biomarker of orthodontic tooth movement reaches its peak after 24 h of force application. The clear aligners, as an alternative to conventional fixed orthodontic treatment, were found to be efficient in correcting mild to moderate lower arch crowding.

Customized Orthodontic Triage During COVID-19 Pandemic.

COVID-19 pandemic necessitates streamlining patient influx in orthodontic office to avoid cross infection between patients, clinicians, and dental health care workers. A customized orthodontic triage has been proposed in this article to schedule patient appointments through priority triaging and, at the same time, provide self-care advice, virtual assistance, and remote monitoring for patient management in elective circumstances.
