Objectives: This study was aimed to assess salivary sodium and potassium concentrations in patients with fixed orthodontic appliances. Methods: In this case-control study, saliva samples (5 cc) were collected from 13 patients with fixed orthodontic appliances before, and 1 week, 1 month and 3 months after the beginning of the orthodontic treatment using the spitting method. Saliva samples were also collected from 10 healthy individuals as controls. The saliva samples were centrifuged at 3000 rpm for 10 minutes and the salivary sodium and potassium concentrations were measured by spectrophotometry. Data were analyzed using independent and paired t-tests. P-value < 0.05 was considered as significant. Results: The salivary sodium and potassium concentrations were almost the same in both groups at baseline (P > 0.05). A significant reduction in sodium and an increase in potassium levels were noted in the case group at 1 week compared with baseline (P < 0.001). At 1 week, the potassium concentration was significantly higher and the sodium concentration was significantly lower in the case group (P < 0.01). The salivary sodium significantly increased while the salivary potassium significantly decreased at 1 month compared with 1 week (P < 0.001). The differences with the control group were also significant (P < 0.05). No significant differences were noted between the two groups at 3 months (P > 0.05). Conclusions: Time has a significant effect on the release profile of sodium and potassium ions from orthodontic appliances. The salivary sodium and potassium concentrations returned to their normal pretreatment values within 3 months after the start of fixed orthodontic treatment.

“…The characteristics of included studies are depicted in Tables 3 , 4 and 5 . This systematic review included 5 RCTs [ 12 , 17 , 26 , 27 , 31 ] and 9 NRSI [ 16 , 18 , 19 , 22 , 25 , 28 – 30 , 32 ]. Four of the included studies [ 12 , 29 – 31 ] investigated the incidence of WSLs, eight studies [ 16 – 18 , 22 , 26 – 28 , 32 ] investigated plaque accumulation as one of the primary outcomes and two studies [ 19 , 25 ] investigated SCB as primary outcome and plaque accumulation as additional outcome.…”

Objective To analyse the available evidence regarding the incidence and severity of white spot lesions (WSLs), plaque accumulation and salivary caries-associated bacteria(SCB) in clear aligners (CA) verses conventional fixed (CF) orthodontic appliances. Methods Electronic searches of MEDLINE, Scopus, Embase, Google Scholar, Clinical trial registry, OpenGrey and ProQuest were done for all relevant studies. Eligibility criteria were; Randomized Controlled Trials and Non-Randomized Studies that compared the incidence and severity of WSLs, plaque accumulation and SCB between CA and CF appliances in patients undergoing orthodontic treatment. The risk of bias(ROB) and certainty of evidence was assessed independently by two reviewers using Cochrane’s ROB and GRADEpro, respectively. Standardized mean difference (SMD) was used to estimate the effect size using STATA 17 software. Results A total of 14 studies met the eligibility criteria, and eight were suitable for meta-analysis. The qualitative results showed lower incidence and severity of WSLs, plaque accumulation, and SCB in CA group compared to CF appliances. The pooled results showed significantly lower plaque accumulation(SMD − 1.58;95%CI:-2.57,0.58;p = 0.002) in CA compared to CF appliances. Conclusions A moderate-quality evidence reveals less plaque accumulation and less SCB in CA, which might be related to the reduced incidence and severity of WSLs associated with CA when compared with CF appliances. However, the results of the present study should be interpreted with caution given the high ROB among some of the included studies as well as the marked heterogeneity across the studies. Clinical relevance For patients who can be treated with either CA or CF appliances, CA may be a better choice concerning oral health.

“…Alshahrani et al [ 41 ] reported significant reductions in the salivary flow rate and pH two months after commencing fixed orthodontic treatment and AlHudaithi and Alshammery [ 42 ] found significant reduction in salivary pH after four to five weeks of de-bonding or at the retention period. At the same time, Anu et al [ 43 ], Dallel et al [ 44 ], and Kouvelis et al [ 45 ] concluded that salivary pH did not significantly change between the studied time points during fixed orthodontic treatment.…”

Salivary pH changes under the effect of stainless steel versus elastomeric ligatures in fixed orthodontic patients: a single-center, randomized controlled clinical trial

2021

View full text Add to dashboard Cite

Background Fluctuations in pH of saliva during a prolonged treatment course influences the enamel demineralization progress, which is one of the complications of fixed orthodontic treatment. This randomized clinical trial aimed to evaluate and compare the short-term effects of stainless steel (SS) versus elastomeric (EM) ligatures on salivary pH in patients scheduled for fixed orthodontic treatment. Methods Seventy participants were enrolled in the study (54 female, 16 male) aged 19–36 years who met specific inclusion criteria. They were randomly selected and allocated into two equal groups through computer-generated randomization. All patients received fixed orthodontic treatment using conventional orthodontic brackets. Two commonly used archwire ligature methods were used: SS and EMs. An unstimulated (resting) salivary sample was collected before tying of the ligatures at T0 (baseline), 2 weeks, 6 (weeks), and 12 (weeks). Salivary pH was measured using a digital pH meter. The level of significance was set at p value < 0.05. Results The salivary pH level was stable between T0 and T1 (6.72 ± 0.14), then significantly and progressively increased from T1 to T2 (6.78 ± 0.13) and from T2 to T3 (6.81 ± 0.14) with (p < 0.05) in the SS group. In the EM group, the salivary pH level was significantly decreased in all follow-up periods; T0 (6.77 ± 0.16), T1 (6.72 ± 0.14), T2 (6.67 ± 0.13) and T3 (6.64 ± 0.13). Conclusion The EM ligatures showed a significant decrease in salivary pH to an unfavorable level, which increased the risk of enamel demineralization. Therefore, EMs as ligature material is preferably should not be recommended in patients with high caries index or inadequate oral hygiene. Trial registration ANZCTR.org.
