Short-term Clinical and Microbiological Performance of Resin-modified Glass Ionomer Cement Containing Chlorhexidine for Atraumatic Restorative Treatment.

Aim: This study evaluated the short-term clinical and microbiological performance of resin-modified glass ionomer cement (RM-GIC) cement containing chlorhexidine (CHX) for atraumatic restorative treatment (ART) in primary teeth.

Materials And Methods: The clinical trial was conducted in 36 children that received ART in primary molars either with GIC (group I, = 18) or GIC containing 1.25% CHX (group II, = 18).

Quantitative assessment of salivary oral bacteria according to the severity of dental caries in childhood.

This study aimed to assess differences in selected oral bacteria in children according to the severity of dental caries. One hundred and thirty-six children, 36-60 months old were divided into three groups according to caries status: caries-free (CF) (n=47), early childhood caries (ECC) (n=40) and severe-early childhood caries (S-ECC) (n=49). Saliva was collected for detection and quantification of selected oral streptococci, Actinomyces naeslundii, Lactobacillus spp.

Genotypic diversity and phenotypic traits of Streptococcus mutans isolates and their relation to severity of early childhood caries.

Background: Early childhood caries (ECC) is an aggressive condition that can affect teeth of young children. This study aimed to evaluate genotypic diversity and phenotypic traits of S. mutans isolated from dental biofilms of children with different caries status in comparison with caries free (CF) children.

Microbiological, lipid and immunological profiles in children with gingivitis and type 1 diabetes mellitus.

Objective: The aim of this study was to compare the prevalence of periodontal pathogens, systemic inflammatory mediators and lipid profiles in type 1 diabetes children (DM) with those observed in children without diabetes (NDM), both with gingivitis.

Material And Methods: Twenty-four DM children and twenty-seven NDM controls were evaluated. The periodontal status, glycemic and lipid profiles were determined for both groups.

Antimicrobial peptides in saliva of children with severe early childhood caries.

Objective: Controversies exist regarding the relationship between the concentrations of antimicrobial peptides (AMPs) and presence of dental caries in children. Thus, the aim of this study was to examine levels of AMPs in saliva of caries-free (CF), early childhood caries (ECC) and severe early childhood caries (S-ECC) children to determine if the levels of these salivary peptides individually or in combinations were related to caries severity and mutans streptococci levels.

Design: 36 to 60 month-old children were selected to participate in this study.

Relationship between the IgA antibody response against Streptococcus mutans GbpB and severity of dental caries in childhood.

Objective: Explore the associations between the severity of dental caries in childhood, mutans streptococci (MS) levels and IgA antibody response against Streptococcus mutans GbpB. Moreover, other caries-related etiological factors were also investigated.

Design: 36-60 month-old children were grouped into Caries-Free (CF, n=19), Early Childhood Caries (ECC, n=17) and Severe Early Childhood Caries (S-ECC, n=21).

Periapical lesions decrease insulin signal and cause insulin resistance.

Introduction: Inflammatory cytokines are associated with decreased insulin signal transduction. Moreover, local oral inflammation, such as that accompanying periodontal disease, is associated with insulin resistance and type 2 diabetes mellitus. The aim of this study was to evaluate the effect of periapical lesions (PLs) on insulin signaling and insulin sensitivity in rats.

Maternal periodontal disease in rats decreases insulin sensitivity and insulin signaling in adult offspring.

Background: Periodontal disease during pregnancy has been recognized as one of the causes of preterm and low-birth-weight (PLBW) babies. Several studies have demonstrated that PLBW babies are prone to developing insulin resistance as adults. Although there is controversy over the association between periodontal disease and PLBW, the phenomenon known as programming can translate any stimulus or aggression experienced during intrauterine growth into physiologic and metabolic alterations in adulthood.

Periodontal disease decreases insulin sensitivity and insulin signaling.

Background: The purpose of this study is to investigate whether local inflammatory events, such as periodontal disease, are able to increase tumor necrosis factor-alpha (TNF-α) plasmatic concentration and decrease insulin sensitivity and insulin signaling in non-diabetic rats.

Methods: Forty-eight male Wistar rats (2 months old) were divided into two groups, with either ligature-induced periodontal disease (LPD) or control conditions (CN). Experiments were performed in both groups 28 days after ligature placement.
