Abstract: Objective This study aims to compare the periodontal indices and the percentage of Streptococcus mutans and Porphyromonas gingivalis between adult patients with bracketless invisible aligner and conventional brackets. Methods Thirty adult patients were divided into two groups(experimental group:15 patients with bracketless invisible aligner; and control group:15 patients with conventional brackets). The clinical periodontal indices[plaque index(PLI), sulcus bleeding index(SBI), and probing depth(PD)] of the observed teeth were examined at three different time points: before orthodontic treatment and in the first and third months after treatment. Dental plaques were collected simultaneously at each time point. We used real-time quantitative polymerase chain reaction to detect and quantitate the number of total Streptococcus mutans and Porphyromonas gingivalis in each sample to determine the percentage of Streptococcus mutans and Porphyromonas gingivalis of total bacteria. Results Before treatment, the periodontal indices and the percentage of Streptococcus mutans and Porphyromonas gingivalis of total bacteria showed no difference between the two groups(P>0.05). Moreover, the periodontal indices and the percentage of Streptococcus mutans and Porphyromonas gingivalis of total bacteria were significantly lower in the experimental group than in the control group(P<0.05); the PLI and the percentage of Streptococcus mutans of total bacteria of the experimental group also increased with time(P<0.05). The SBI, PD, and percentage of Porphyromonas gingivalis of total bacteria also showed no difference between the two groups(P>0.05). The periodontal indices and the percentage of Streptococcus mutans and Porphyromonas gingivalis of total bacteria of the control group also significantly increased with time(P<0.05). Conclusion Compared with the use of conventional brackets, the bracketless invisible aligner technique is better for periodontal health, although it adversely affects the oral health.
