“…Similarly, iron has a confirmed role in the growth and development, as well as the synthesis of the red blood cells and the transfer of oxygen from the lungs to the tissues (2)(3)(4)(5)(6). Further, a significant correlation was reported between iron deficiency and dental caries (8,13,(19)(20)(21)(22)(23). Furthermore, iron supplements in Iran are mainly prescribed as the iron drops.…”

BackgroundAdequate nutrition plays a major role in physical growth and development. In addition, nutritional requirements may vary depending on body size, physical activity, and health status. Iron is considered as an important element that is required by the human body (1) and is found in all viable tissues including the enamel, dentin, and dental pulp (2-4). Children also need iron for growth and development, as well as the synthesis of red blood cells. The highest amount of iron in the human body is found in hemoglobin present in red blood cells, which has the important task of carrying oxygen from the lungs to the tissues (4-6). Further, iron supplements in Iran are often in the form of iron drops. However, tooth discoloration is a common complication of iron drop consumption (3,(7)(8)(9). Edible iron compounds available in the Iranian market are

“…Orthodontic patients may benefit from probiotics to prevent the development of white spot problems brought on by tooth enamel decalcification. In particular, Streptococcus mutans , recognized as the main cause of dental caries, is more prevalent in the plaque of people receiving orthodontic therapy than in the plaque of people not receiving it [ 14 , 15 ].…”

Background and aim: Orthodontic brackets can be a significant factor in enamel demineralization due to their complex structure, which makes brushing the teeth difficult and promotes the accumulation of food particles and dental plaque. The fact that metal braces have the highest surface tension and are more likely to cause enamel demineralization, which can result in the development of white spot lesions and enamel caries, is of critical significance to doctors, dentists, and patients. Probiotics have a beneficial effect in preventing and treating oral infectious diseases like tooth decay, gingival disorders, and bad breath. Research has shown that taking probiotics lowers the amount of Streptococcus mutans in the body. There has not been much research done to examine the results of administering a probiotic medication locally. This study was conducted to examine the effectiveness of three separate probiotics in the prevention of S. mutans accumulation in plaque surrounding orthodontic braces. Materials and methods: A randomized controlled trial was conducted. The volunteers for each group were chosen using a straightforward random method. The sample size was 160 empirically determined subjects. They were divided as follows: study group 1 received probiotic lozenges (n=40). Study group 2 received probiotic sachets (n=40). Study group 3 received probiotic beverages (n=40). Group 4 was the control group, those who did not get probiotics (n=40). The samples were then plated onto culture media to test for Streptococcus mutans . S. mutans colonies were counted using a computerized colony counter. Results: The mean values of colony forming units (CFU/mL) of S. mutans at baseline in the control group were 354±23.6, while they were 232±41.7 at the end of the observation duration. The difference was non-relevant statistically (p=0.793). The mean values of CFU/mL of S. mutans at baseline in the group taking probiotic lozenges were 358.7±39.93, while they were 57±10.12 at the end of the observation duration. The difference was relevant statistically (p=0.021). The mean values of CFU/mL of S. mutans at baseline in the group taking probiotic sachets were 321.36±41.67, while they were 215.5±22.66 at the end of the observation duration. The difference was relevant statistically (p=0.043). The mean values of CFU/mL of S. mutans at baseline in the group taking the probiotic drink were 335.76±40.12, while they were 75.1±28.74 at the end of the observation duration. The difference was relevant statistically (p=0.032). Conclusion: There was a significant decline in the number of colonies of S. mutans in all three forms of probiotics; however, the decline was greatest in the study participants taking probiotic lozenges.

Background10-Hydroxy-2-decenoic acid, an unsaturated fatty acid is the most active and unique component to the royal jelly that has antimicrobial properties. Streptococcus mutans is associated with pathogenesis of oral cavity, gingivoperiodontal diseases and bacteremia following dental manipulations. In the oral cavity, S. mutans colonize the soft tissues including tongue, palate, and buccal mucosa. When considering the role of supragingival dental plaque in caries, the proportion of acid producing bacteria (particularly S. mutans), has direct relevance to the pathogenicity of the plaque. The genes that encode glucosyltransferases (gtfs) especially gtfB and gtfC are important in S. mutans colonization and pathogenesis. This study investigated the hydroxy-decenoic acid (HDA) effects on gtfB and gtfC expression and S. mutans adherence to cells surfaces.MethodsStreptococcus mutans was treated by different concentrations of HPLC purified HDA supplied by Iran Beekeeping and Veterinary Association. Real time RT-PCR and western blot assays were conducted to evaluate gtfB and gtfC genes transcription and translation before and after HDA treatment. The bacterial attachment to the cell surfaces was evaluated microscopically.Results500 μg ml-1 of HDA inhibited gtfB and gtfC mRNA transcription and its expression. The same concentration of HDA decreased 60% the adherence of S. mutans to the surface of P19 cells.ConclusionHydroxy-decenoic acid prevents gtfB and gtfC expression efficiently in the bactericide sub-concentrations and it could effectively reduce S. mutans adherence to the cell surfaces. In the future, therapeutic approaches to affecting S. mutans could be selective and it’s not necessary to put down the oral flora completely.
