The effectiveness of a caries preventive program in mothers and infants – An 18- month follow-up study

Background/purpose: MS and LB, the primary bacteria groups responsible for dental caries, and high levels of these bacteria in the mother promote transmission from mother to infant. The aim of this study was prevention of maternal MS and LB transmission on infants by using different preventive strategies and inhibition of early childhood caries proggession. Materials and methods: This study was conducted with 50 mother-child pairs who were randomly allocated into either a study group or a control group (n = 25 each). Mothers in the study group were enrolled in a detailed preventive program that included elimination of dental caries with restorative and antibacterial procedures, whereas those in the control group received only a single episode of oral-health education. Results: After 18 months, significant MS and LB inhibition was observed in the study group (p < 0.0001). In addition, caries prevalence in the infants in the study and control groups was 0% and 20% respectively, and the difference between the two groups was statistically significant (p = 0.020). Conclusion: These results indicate that primary preventive intervention and oral-health instruction can significantly inhibit the MS and LB levels of mothers and prevent caries in their children during the early years of life. © 2020 Association for Dental Sciences of the Republic of China2013/02This study was financially supported by the Scientific Research Project of Kirikkale University , Turkey (project number: 2013/02 )

The effects of antibacterial solutions on microorganisms isolated from infected root canals in vivo

Objective: This study assessed the in vivo antimicrobial activity of NaOCl, Chx, Ca(OH)2, and H2O2 against five different microorganisms: Enterococcus faecalis, Porphyromonas endodontalis, Streptococcus salivarius, Lactobacillus sp., and S. aureus. Study design: Eighty infected teeth in seventy patients with pulpal or periapical pathology were studied. After preparing a standard access cavity. Sterilized paper points were used to take samples from the root canals. These were incubated in test tubes at 37°C for 72 hours. Of the resulting bacteria, the five most frequent strains were examined. The teeth were divided into four equal groups. After preparing the root canal using the step-back technique until a number 55 file, each group was subjected to one of the following irrigation solutions: 2% chlorhexidine gluconate (Chx), 5% NaOCl, Ca(OH)2 in distilled-water, or 3% H2O2. After irrigation, a temporary filling was placed in each cavity. The same irrigation procedure was repeated three and six days later. Then, the microbiologic sampling was also repeated. The chi-squared test was used for statistical comparisons. Results: Of the irrigants tested in this in vivo study, chlorhexidine was the most effective against all the microorganisms isolated from infected root canals, followed by NaOCl, Ca(OH)2, and H2O2. However, differences among the three groups were not statistically significant, except against Enterococcus faecalis (p&gt;0.05). Conclusions: Our results did highly confirm the fact from previous studies that chx with 2% percent is the most effective antibacterial agent after three consecutive irrigations. Furthermore, in vitro and in vivo studies are necessary to assess whether the Chx imparted substantive dissolve organic material. © 2006 Taylor and Francis Group, LLC

Prevalence of breath malodour in 7-11 year old children living in Middle Anatolia, Turkey

WOS: 000259377900010PubMed: 18839725Objective: To determine the prevalence of breath malodour and to assess the relationships between breath malodour parameters such as dental caries, habitual mouth breathing, tooth-brushing, and the frequency of upper respiratory-tract infection. Methods: A total of 628 healthy children (327 boys, 301 girls) ranging in age from 7 to 11 who were living in Kirikkale, Middle Anatolia, Turkey were included. Subjects who were taking antibiotics, having any Suspicion of upper respiratory tract infection, sinusitis or tonsillitis at the time of survey were excluded from the study. Oral malodour assessment was carried out by organoleptic method. The DMFT/S was used to record caries. Pearson's correlation coefficients were calculated to determine the association of each clinical variable to organoleptic oral malodour rating. Bivariate logistic regression analysis was performed to detect the degree of association between oral malodour and various dental-habitual parameters. Results: The prevalence of halitosis was 14.5%. Organoleptic oral malodour ratings were significantly higher in older age groups. Gender, frequency of tooth brushing, habitual mouth breathing did not influence oral malodour ratings. D(T), DMF(T), d(s) played the most significant role in higher oral malodour ratings, followed by d(t) and df(s). The frequency of tooth brushing, habitual month breathing did not contribute to the prevalence of halitosis:. Conclusion: Age, prevalence and severity of dental caries were significantly related to breath malodour
