In recent years, orthodontics, a specialized branch of dentistry, has evolved considerably in terms of both techniques and materials used. Aimed at correcting dental malocclusions and craniofacial anomalies, it improves the functionality and aesthetics of the face and oral cavity. However, orthodontic treatment, in its developmental stages, may induce oxidative stress (O.S.) phenomena, with an increase in the production of reactive oxygen species (ROS), damaging the dental and periodontal tissues involved, affecting the short-, medium- and long-term results. Studies on the antioxidant effects of natural products (e.g., resveratrol, green tea, turmeric, etc.) in the medical field have aroused considerable interest in recent years. A systematic literature review was conducted on the PubMed, Scopus, and Web of Science databases using natural products (N.P.s), O.S., and orthodontic as keywords. The study aims to consider the determinants of the increase in ROS occurring during orthodontic treatment and the possibility of natural products being able to control and neutralize biochemical phenomena by restoring the physiological process in which the balance between the production of ROS and the ability of the body’s antioxidant system to neutralize them is in favor of the latter.

Liver abscess caused by some kinds of Streptococcus group such as Streptococcus bovis group has been recognized to associate with colorectal cancer. Streptococcus milleri group with liver abscess has not been received much attention in this point of view. Here, we report the case of a 63-year-old man who developed liver abscess with S. intermedius, which belongs to the S. milleri group. We confirmed that this case was accompanied by cecal carcinoma by colonoscopy. The tumor was a pathological lead point of intussusception of cecum. On the 26th day, open right hemicolectomy was performed. In this case, bacterial endophthalmitis was a complication due to bacteremia. The patient underwent ophthalmic surgery on the 98th day. Research investigating 16S rRNA of the mucosal colon microbiome reported that the S. intermedius gene was upregulated in patients with colorectal carcinoma. It is recommended that liver abscess with S. intermedius bacteremia should alert the clinician about the risks of carcinoma of the colon and abscess formation in distant organs. We here list the case reports of liver abscess caused by Streptococcus other than S. bovis group, which was associated with colonic carcinoma, and suggest the need for further research about S. milleri group.

“…However, there are no available data suggesting that gender could be an important factor to explain the difference in oral colonization. Otherwise, it is reported that neonates and subjects aged over 65 years may have a higher incidence of oral candidosis [21, 22]. It is noteworthy that age extremes were not included in either of the groups evaluated in the present series.…”

Summary. This study was designed to investigate the oral yeast colonization rate of household contacts of AIDS patients. Sixty‐four AIDS household contacts were sequentially enrolled along with 103 HIV‐negative blood bank donors (control group). Samples were obtained by swabbing the oral mucosa. Yeast isolates were identified by classical methods and antifungal susceptibility testing was performed according to NCCLS microbroth assay. Candida spp. was recovered from the oral cavity of 33% of the AIDS household contacts, in contrast with 14% of the control group (P = 0.003 or P = 0.04 after adjusting for oral prosthesis use). Candida albicans was the most frequently isolated species in both groups. All of the isolates were susceptible to fluconazole, itraconazole and ketoconazole. In conclusion, we were able to demonstrate a higher colonization rate in the AIDS household contacts group compared with the control group. No resistant isolates to antifungal drugs was observed. We suggest that the contact with AIDS patients may play a role as a risk factor for developing oral colonization by Candida spp.
