AI Article Synopsis
- The study examined the impact of fixed orthodontic appliances on the oral health of 30 patients over a medium-term period, focusing on factors such as decay, plaque, and gingival health.
- At the follow-up (T1), 60% of patients showed a worsening in oral health, indicated by increased plaque and gingival indices, with significant correlations between plaque and gingival conditions.
- Results indicated a rise in specific bacteria, particularly Actinomyces, after appliance bonding, suggesting that orthodontic treatment can alter oral microbial diversity and emphasizing the need for comprehensive monitoring of oral health during orthodontic therapy.
Article Abstract
Background: This pilot study aimed to investigate how fixed orthodontic appliances simultaneously applied on the upper and lower arches affect the oral environment in the medium term.
Methods: The oral status of 30 orthodontic patients was evaluated using the number of decay-missing-filled teeth (DMFT), plaque (PI), and gingival indices (GI) before bonding of fixed orthodontic appliances (T0) and during the therapy (T1). Besides, the gingival crevicular fluid (GCF) and a dental plaque were collected. Samples were analyzed for selected Candida sp. and for 10 selected oral bacteria using mass spectroscopy and multiplex polymerase chain reaction, respectively.
Results: In 60% of patients, deterioration of the oral status (demonstrated by the increase in PI) was recorded (p < 0.05). Moreover, the changes in PI correlated with those of GI (p < 0.001). At the T1 time point, the mean representation of Actinomyces sp. in the total prokaryotic DNA in GCF and dental plaque of individual patients increased compared to T0 (p < 0.05). The probability of finding any of the 7 selected periodontal bacteria combined with Candida sp. was 10 times higher in patients in whom PI deteriorated between T0 and T1 (p < 0.01).
Conclusions: Changes in the oral microbial diversity and an increase in PI were observed in the medium term after bonding of orthodontic appliance. Our study highlights the importance of a complex approach in this type of research as the association between clinical characteristics and combined microbial parameters is higher than when evaluated separately.
