Longitudinal Evaluation of Oral Health Among Orthodontic Patients Prior Treatment, During Treatment and Post-Treatment

Aim: to evaluate oral health status among orthodontic patients: before, during, post
treatment completion. Subjects & methods: Twenty-eight patients were selected from
Outpatient clinics seeking Orthodontic treatment, Faculty of Dental Medicine, Al-Azhar
University, Cairo, Egypt. A self-administrated questionnaire was prepared covering
oral hygiene practice, oral hygiene cleaning aids and previous oral prophylaxis. Oral
health status of each patient was assessed using: Gingival bleeding index (GBI), Plaque
index (PI), Oral Hygiene Index (OHI-S) which performed for each patient 3; prior to,
during and after orthodontic treatment termination. Measurement of probing pocket
depth (PPD) and radiographic examination were done before treatment and 3 months
following treatment termination. Results: No significant difference was observed
between mean PI & GBI recorded before orthodontic treatment(T1) and that measured
three months (T4) following treatment completion but there were significant differences
between these measurements during treatment with both before and after treatment;
no significant difference between males and females. PPD recorded no differences
between any evaluation times. OHI-S recorded higher scores during treatment
period with statistically significant difference when compared with recorded scores
initially; however, it did not differ significantly with that of at after 3 from orthodontic
termination. Conclusion: Dental plaque accumulation among orthodontic patients can
aid in development of gingival and dental effects, as it seems likely that orthodontic
appliances have potentiality to increase oral microbial population. Orthodontic patients
should be monitored and motivated for proper oral hygiene to avoid risk of new caries
and periodontal diseasesAim: To compare, through cone-beam computed tomography (CBCT), the root
resorption of two different mini-implant-assisted modalities in intruding the maxillary
incisors. Subjects and Methods: The present study composed of 26 patients (males,
females) aged between 12-18 years who had deep bite and need maxillary incisors
intrusion. They were randomly selected and divided into two group: anterior miniimplant group (AMG) and posterior mini-implant group (PMG). In the AMG,
approximately 40 g of force was applied per side with elastic chains and in the PMG,
with beta-titanium wires with modification of three pieces intrusive arch. This study
was conducted on cone beam computed tomography scans taken before intrusion
and after 18 weeks of intrusion. Results: The incisors showed a significant reduction
in length, this amount was greater in AMG than PMG. Conclusion: Posterior miniimplants assisted maxillary incisors intrusion show less root resorption than anterior
mini-implant assisted maxillary incisor intrusion
