Masticatory performance and oral health related to quality of life before and after orthodontic treatment: a systematic review and meta-analysis.

Masticatory performance is considered an important step in the beginning of the digestive process and considering the patient's aesthetic and functional factors, it is necessary to choose appropriate treatments. Based on the evidence during orthodontic treatment, the restoration of the physiological function of masticatory performance should not be neglected. The present study aimed to evaluate the association between orthodontic treatment and improved masticatory performance and oral health related to quality of life. In the present study, all articles published till the end of August 2023 were extracted by two trained researchers independently through a search in databases like PubMed, Scopus, Science Direct, ISI, Web of Knowledge, Elsevier, Wiley, and Embase, and Google Scholar search engine using keywords and their combinations. Data analysis was done using the fixed effects model in a meta-analysis, by STATA (version 17); a P-value of less than 0.05 was considered significant. Based on the results, the mean difference in masticatory performance between pre-treatment and post-treatment was 2.23 (MD: 2.23; 95CI, 2.17, 2.29. p<0.01; I2= 99.98%; p<0.01). The mean difference in oral health related to quality of life between pre-treatment and post-treatment was -32.23 (MD: -32.23; 95CI, -33.35, -31.11. p<0.01; I2= 97%; p<0.01). Orthodontic treatment had a positive effect on masticatory performance and improved the quality of life of patients after treatment.

Risk factors associated with implant sites prepared by orthodontic treatment: a systematic review.

The patient's health and quality of life would probably be improved with dental implant. This study aimed to evaluate the risk factors associated with dental implants place by orthodontic treatment. In this study, information on risk factors associated with implants of sites prepared, radiology stereotypes and hospitalized were obtined from databases such as Scopus, Google scholar and PubMed, and 58 articles were included for this purpose. After analyzing the articles, 24 articles were not accepted and 34 articles were accepted, then, 16 articles were miscarriage and 18 articles were scientific sources. The results showed that orthodontic treatment has a significant effect on a person's sense of beauty and would possibly increase self-confidence and quality of life. The stability of the implant in the healing phase depends on the quality and quantity of the bone. Also, the width of the bone is one of the important issues in creating a successful treatment. When an implant fails, problems and symptoms of failure usually occur within the first year after surgery. After one year, there is only about a 1% chance of failure, and on average only 1% of all implants fail each year.

Comparative evaluation of bacterial colonization on removable dental prostheses in patients with COVID-19: A clinical study.

STATEMENT OF PROBLEM: In the outbreak of COVID-19, coinfections and even superinfections in the background of SARS-CoV-2 viral infection have been reported. Such bacterial and fungal strains may be colonized in different tissues and organs, including the oral cavity. Whether infection with COVID-19 could increase colonization of different bacterial strains on removable dental prostheses is unclear. PURPOSE: The purpose of this clinical study was to compare bacterial colonization on removable dental prostheses in patients with COVID-19, before versus after diagnosis. MATERIAL AND METHODS: Two sex- and age-matched groups of complete-denture-wearing participants (N=60) with and without a positive diagnosis for COVID-19 were enrolled in the study. Swabs were used at 2 different time intervals to sample areas of the dentures, which were then cultured and the colony smears Gram stained. A statistical analysis was conducted by using the Mann-Whitney U test (α=.05). RESULTS: Streptococcus species (93.3% versus 40.0%, P=.047) and Klebsiella pneumonia (46.7% versus 13.4%, P=.036) were detected more frequently in the COVID-19-positive group. CONCLUSIONS: Higher rates of bacterial colonization, especially with Streptococcus species and Klebsiella pneumonia, were detected on removable dental prostheses after COVID-19 infection.

Comparative Efficacy of Low-Level Laser Acupuncture and Cupping for Treatment of Patients with Myofascial Pain Dysfunction Syndrome: A Double-blinded, Randomized Clinical Trial: Comparison of the Effects of LLL Acupuncture and Cupping.

Background: Myofascial pain dysfunction syndrome (MPDS) is among the most common causes of facial pain. This study compared the efficacy of low-level laser (LLL) acupuncture and cupping for the treatment of MPDS. Materials and Methods: This double-blind, before-after, randomized clinical trial evaluated 60 MPDS patients that were divided into two groups for LLL acupuncture (808 nm, 0.5 W, 30 J, 4 J/cm2 energy density, 60 seconds; group 1), and cupping (group 2) of masticatory muscle trigger points. Both treatments were performed for maximally eight sessions once every other day. The level of pain at the trigger points was measured upon admission, before and 5 minutes after treatment in each session, at ten days, and two months after treatment completion by a visual analog scale (VAS). The painless maximum mouth opening (MMO) and patient satisfaction with treatment were also assessed at the time as mentioned earlier points. Results: Averagely, 4.5 treatment sessions were required to achieve a 50% reduction in VAS pain score, with no significant difference between the two groups (P=0.9). Both treatments significantly decreased the number of trigger points and pain score, but this reduction occurred significantly sooner in the cupping group (P=0.01). MMO significantly improved in both groups after treatment with no significant difference between them (P=0.2). Patients were significantly more satisfied with LLL acupuncture (P=0.05). Conclusion: Both cupping and LLL acupuncture are equally effective for MPDS; thus, the patient can choose the type of treatment after receiving sufficient information regarding the two modalities.

Geographic Stomatitis with Multiple Areas Involvement of Oral Cavity: A Case Report and Review of Literatures.

Background: Geographic stomatitis is an uncommon migratory benign lesion of oral mucosa with unknown etiology. It can affect all the areas of the oral mucosa, but the dorsum and lateral borders of the tongue are the most commonly involved areas called geographic tongue. The clinical appearance of this condition is the oval or circular erythematous areas with irregular elevated keratotic borders. These characteristic features of geographic stomatitis are diagnostic for all clinicians when appearing on the dorsum of the tongue, despite other affected areas of oral mucosa that can confuse clinicians. This condition may be associated with some diseases such as psoriasis, Reiter's syndrome, and atopic conditions, so the clinicians should rule out these diseases and diagnose the geographic stomatitis. Case Report: A 17-year-old male attended to our department for a routine dentistry checkup. During the intraoral examination, we found multiple erythematous areas surrounded by a thin white border on different surfaces of his oral cavity. His extraoral examinations were completely normal. Conclusion: Due to the rarity of this lesion on the other sites of oral mucosa rather than dorsum and lateral borders of the tongue such as labial mucosa, buccal mucosa, the floor of the mouth, ventral surface of the tongue, and palate, it is necessary to report, study and evaluate each case of this condition that clinicopathologic findings have confirmed this diagnosis, to treat and advice these patients on the best approach.
