Orthodontic appliances did not increase risk of dental caries and periodontal disease under preventive protocol

Abstract

Objectives: To assess periodontal parameters and microbial species levels after orthodontic appliance placement in patients who received oral hygiene instructions and who were monitored and motivated throughout the study. Materials and Methods: The Periodontal Index was recorded and saliva collection was performed before (T0) and 30 (T1), 60 (T2), and 90 (T3) days after orthodontic appliance placement in 15 patients (mean age 17.53 6 8.0 years). Analysis was carried out using checkerboard DNA-DNA hybridization. Nonparametric statistical analysis was performed. Results: The Periodontal Index did not change. The total amount of the purple and red complexes and Candida species showed a significant decrease from T2. The green, yellow, and orange complex showed a significant decrease at T3. The specific species analysis showed that Prevotella nigrescens, Pseudomonas putida, Fusobacterium periodonticum, Pseudomonas aeruginosa, Peptostreptococcus anaerobius, and Tanerella forsythia showed high incidence before bonding, and their levels decreased at T2 and T3. Only Porphyromonas gingivalis showed increased levels at T2 and displayed the highest level at T3. The Streptococcus group decreased their levels from T2 onward. Conclusions: A dynamic change in microbial levels was identified. The decrease in the levels of complexes present was only possible due to the mechanical method of oral hygiene implemented in this sample. (Angle Orthod. 2019;89:25-32.)

Relationship between orthodontic treatment and dental caries: results from a national survey

“…In another review article, the authors reported orthodontic treatment to be a risk factor for dental caries, especially in younger patients 3 . However, a recent study 16 reported that orthodontic treatment is not a risk factor for dental caries if an appropriate oral-care protocol is implemented.

“…They emphasised that clinicians should educate patients about prevention of dental caries before orthodontic treatment is initiated and should not recommend orthodontic treatment to patients who are not motivated to perform good dental hygiene. Malocclusion in itself may also be a risk factor for dental caries 16 , and it has been reported that patients who are receiving orthodontic treatment have an improved ability to manage their oral hygiene 17 . Moreover, orthodontic treatment is indispensable in resolving malocclusion, which may be mild (such as crowding) or severe (such as impaction or abnormal tooth eruption), causing serious oral dysfunction 1 .…”

Healing without Surgery: A Case of Supernumerary Tooth,

“…A preventive protocol, based on motivation and instruction on the correct oral hygiene maneuvers before and during orthodontic treatment, decrease the risk of dental caries and periodontal disease in patients with fixed corrective devices This statement was demonstrated through a study that assessed periodontal parameters and levels of microbial species after placement of fixed orthodontic appliances in patients who received oral hygiene instructions and were monitored throughout the duration of treatment.The periodontal index registered initially did not change to the 90-day control, the total amount of the purple and red complexes and the candida species decreased at T2 (60 days from the placement of the orthodontic appliance), the green, yellow, and orange complex showed a significant decrease at T3 (90 days from the placement of the orthodontic appliance).

“…The Streptococcus spp. decreased levels from T2 onwards [13,14]. In light of the above, the early diagnosis of supernumerary teeth is important for an accurate treatment plan.…”
