“…Low-level laser therapy (LLLT) is one of the newer approaches proposed to control pain [19]. Lasers have been used in the medical and dental areas as an alternative to control pain [20][21][22]. They hold promise in controlling orthodontic pain because lasers do not have the side effect of the non-steroidal anti-inflammatory drugs.…”

The objective of this research was to compare the effect single low-level laser therapy (LLLT) irradiation on pain perception in patients having fixed appliance treatment in the clinic of orthodontics. Sixty-two patients were recruited to participate in this randomized, double-blinded, placebo-controlled study. The patients were assigned to four groups: group I-laser on the right side; group II-placebo on the right side; group III-laser on the left side; group IV-placebo on the left. The laser or placebo was applied before separation, 24 and 48 h after separation of their first permanent molars in the lower arch. Just after the separation, the average of the pain for the placebo group was 1.6, significantly greater than the average of 1.1 registered for the laser group (p = 0.013). After 24 h and before the new irradiation, the values registered among the different groups did not show any differences. In relation to the gender, only after the first irradiation in placebo group, the female had a level of pain (0.1) significantly higher (p = 0.04) compared to male, and after 48 h, the group where the laser was applied had a difference (p = 0.04) among the gender with a value of lower pain for men (0.6) than for women (1.6).The laser irradiation to minimize the pain was only effective when applied immediately after treatment and separation. In general way, there were no differences between the genders, except after the first placebo group irradiation in which the female had a significantly higher level of pain compared to male and after 48 h. The pain cycle observed in this study had its peak in 24 h, both for laser's and placebo's group.

Objective: This systematic review and meta-analysis updated the effects of photobiomodulation therapy (PBMT) on pain, the Foot Function Index (FFI), and the effects on fascial thickness in adults with acute or chronic plantar fasciitis (PF). Methods: A systematic literature search was conducted in the PubMed (Public/Publisher MEDLINE), EM-BASE (Excerpta Medica Database), and CINAHL (Cumulative Index to Nursing and Allied Health Literature) databases. Two researchers independently screened titles and abstracts of the retrieved studies for eligibility. A random-effects model was used for this meta-analysis. Subgroup meta-analyses were conducted to evaluate the influence of PBMT in pain and foot function under investigation and the study design on the overall weighted mean effect size. Results: From a total of 3865 studies, 7 randomized controlled trials were selected after final review and 4 were selected for meta-analysis. There was a significant difference between PBMT and control for Visual Analog Scale (Chi 2 = 29.30; p < 0.00001) with an I 2 value of 90% in favor of PBMT versus the control. The overall effect of PBMT was statistically significant (p < 0.02) with PBMT favoring for thickness of the plantar fascia reduction. FFI between PBMT and control group [Chi 2-83.46, df = 1 (p < 0.00001)]; I 2 = 99% in favor of the PBMT. Conclusions: This meta-analysis presents evidence that PBMT is an effective treatment modality to reduce pain and improvement of foot function in patients with chronic PF, however, a broad discrepancy was found in the PBMT dosimetry. The ideal treatment parameters for PF need to be elucidated.

“…In a meta-analysis, Andiappan et al reported that quality of life related with oral health in adolescents and adults, was higher in individuals who received treatment for malocclusion than in those who suffered malocclusion but did not undergo treatment. The beneficial effects of OT on dental aesthetics can be observed from the first few months; however it can also determine some unwanted effects in patients, such as pain (Deana et al, 2017) and anxiety (Long et al;Krishnan, 2018), thus diminishing the patient's quality of life during the OT. In order to estimate the impact of the placement of the first arch on the ability to carry out EDAs, we applied a questionnaire to patients undergoing OT in which we assessed functional limitation (Q2 and 3), physical incapacity (4), psychological disability (8, 9), physical pain (1, 5 and 6) and oral hygiene (7).…”

Orthodontic treatment (OT) is essential for the aesthetic and functional rehabilitation of the chewing apparatus, however it may lead to certain complications which can have a negative impact on patients' everyday lives. The study included patients of the Dental Teaching Clinic of Universidad de La Frontera who were undergoing OT for the first time, with the placement of their first orthodontic arch. To analyse the impact of the placement of the first arches on everyday activities (EDA), patients completed a questionnaire with questions relating to their oral condition, including: functional limitation, physical impairment, psychological malaise, physical pain and oral hygiene. The impact on EDAs was classified as high, moderate or low. The chisquared test, Student's t-test and Spearman's coefficient were applied, using a significance threshold of 5 %. Statistical analysis used the SPSS software, v. 22.0. The variables were analysed by sex and age-band. Difficulty in brushing their teeth, eating and speaking were the limitations on EDAs most frequently reported by the patients. Females presented higher scores than males (p=0.003), showing that they suffer a greater negative impact on EDAs than do males. The majority of the patients presented a low impact on EDAs after the placement of their first orthodontic arches. Physical pain after installation, and difficulty in adapting to the orthodontic apparatus were factors determining a negative impact on EDAs, affecting sleep, speech, eating and oral hygiene of patients after starting OT.
