“…Furthermore, the reported increased presence of S. mutans and lower level of oral hygiene should be considered in the orthodontic treatment planning for mouth breathers subjects, where the increased difficulties in maintaining satisfactory levels of oral hygiene, combined with the use of fixed multibracket appliances [ 14 ], could determine an increased risk of iatrogenic effects such as dental caries or enamel demineralization, directly related to the level of oral hygiene and S. mutans colonies during the orthodontic treatment [ 19 , 20 ]. Thus, in the orthodontic treatment of mouth breathing subjects, the use of removable appliances such as clear aligners, rather than fixed vestibular of lingual multibracket appliances, should be encouraged to counteract the individual predisposition to lower oral hygiene conditions [ 21 – 23 ].…”

Objective This is a 6-month observational case-control study that aims to estimate plaque index (PI), salivary flow, buffering capacity of saliva, and specific Streptococcus mutans (S. mutans) and Lactobacillus rates in a mouth breathing late adolescents sample, after a professional oral hygiene procedure and home oral hygiene instructions. Subjects and Methods A sample of 20 mouth breathing late adolescents/young adults (average: 19.2 ± 2.5; range: 18–23 years) and a matched control group of nose breathing subjects (average: 18.3 ± 3.2; range 18–23 years) were included in the study. All the participants were subjected to a professional oral hygiene procedure and appropriate home oral hygiene instructions (t0). After three months (t1) and six months (t2), the PI, salivary flow, buffering capacity of saliva, and S. mutans and Lactobacilli rates were recorded. Results The mean buffering capacity of saliva and the salivary flow rate showed no significant difference between the two groups, all over the observational period. For PI, a significantly higher mode (score 1 of PI) was observed in the study group at t1 (score 0 = 35% of subjects; score 1 = 60%; score 2 = 5%) and t2 (score 1 = 65% of subjects, score 2 = 35%), with respect to control group. Furthermore, mouth breathing subjects show a significant 4 times higher risk to develop S. mutans CFU > 105 (CI lower limit: 0.95; CI upper limit: 9.48; chi-square: 4.28; p = 0.03), with respect to the control subjects. Conclusions Mouth breathing late adolescents show a significantly higher risk to develop S. mutans CFU > 105 and an increased level of PI. Interceptive orthodontic treatments in growing subjects, like palatal expansion, are encouraged to improve the nasal air flow. In older subjects, orthodontic treatments should be performed with removable appliances like clear aligners, in order to allow a better oral hygiene level.

“…WSLs can form due to salivary pH, flow rate and buffer capacity decline associated with poor oral hygiene. 7,8 Additionally, the results showed a modification in several electrolyte rates, which may have been due to a disturbance in the ionic balance on tooth surfaces leading to WSLs. Orthodontic treatment can also produce gingival complications and aggravate existing lesions, which would affect salivary electrolytes.…”

“…6 The pH of saliva, calcium level, and oxidative status can be affected during orthodontic treatment, leading to enamel decalcification that is clinically revealed by the appearance of white spot lesions (WSLs), especially when associated with poor hygiene. 7 In this framework, the purpose of this study was to investigate variations in salivary parameters, notably changes in the physicochemical, biochemical, and oxidative stress parameters related to the type of orthodontic appliances used.…”

Objectives To evaluate the effect of orthodontic appliances on physicochemical, biochemical, and oxidative stress changes in salivary parameters during treatment. Materials and Methods A cohort study was conducted with 112 healthy patients. Salivary samples were taken at baseline, 1 month, and 9 months after placement of the orthodontic appliances used in treatment. Results A statistically significant difference was observed in certain examined salivary parameters, including enzymes, electrolytes, and oxidative stress markers. Conclusions The use of aligners had a lower prevalence of disturbing salivary parameters. Orthodontist must consider these changes to prevent the occurrence of white spot lesions.

“…Enamel demineralization has a high prevalence among orthodontic patients with fixed orthodontic appliances (Benkaddour et al, 2014, Julien et al, 2013, Lucchese and Gherlone, 2013). Eliminating or reducing the risk of enamel demineralization along the perimeter of orthodontic brackets is a continuous and an ongoing struggle for clinicians and patients alike.…”

ObjectiveTo compare the enamel demineralization around the two precoated adhesive bracket systems, APC Flash-Free and APC PLUS (3M Unitek, Monrovia, CA, USA), in clinical settings.Material and methodThis prospective experimental in-vivo study included 40 premolar teeth, which were planned for extraction due to orthodontic purposes. They were divided into two groups (Group A; n = 20 teeth were bonded with APC Flash Free ceramic brackets and group B; n = 20 teeth were bonded with APC Plus ceramic bracket). After four weeks, the teeth were extracted, sectioned, and examined under the Scanning Electron Microscope (SEM) to evaluate the amount of demineralization from the enamel surface to the deepest point.ResultsFindings revealed that the mean values of demineralization under SEM were significantly higher in APC Plus compared to APC Flash Free (149.95 µm vs. 112.96 µm, respectively) (P < 0.05). The difference between the two systems was mainly found in the middle part of the facial surfaces, while there were no differences between the two systems in the proximal parts.ConclusionThe enamel demineralization around APC Flash-Free adhesive bracket system was significantly less than that of APC plus Adhesive bracket system, which can be due to the absence of the caries promoting adhesive flash during tooth bonding using the flash free system.
