Does the presence of sucrose in pediatric antibiotics influence the enamel mineral loss and the Streptococcus mutans counts in dental biofilm?

The role of antibiotics containing sucrose on the formation of dental caries is still controversial. This study aimed to investigate the effect of two antibiotics (amoxicillin and potassium clavulanate suspension), with and without sucrose, on human dental hardness and Streptococcus mutans counts in dental biofilm. Primary tooth fragments (n=72) were coated with nail varnish leaving a window of 2.

Clinical and oral findings in an Afro-Brazilian family with Gorlin-Goltz syndrome: case series and literature review.

Gorlin-Goltz syndrome (GGS) seems to be unusual in black persons. The authors present an Afro-Brazilian family case report of GGS. The main complaint of the index case was a painless swelling of the left mandible, which was diagnosed as an odontogenic keratocyst.

Topical effect of a medically prescribed pediatric antibiotic on dental biofilm: a cross-over, in situ study.

Objective: This study aimed to investigate the possible topical effect of a broad-spectrum antibiotic on dental biofilm formed in situ in the absence or presence of sucrose.

Methods: A crossover study was conducted in three phases of 14 days each, during which 11 volunteers wore palatal devices containing 6 enamel blocks covered with meshes to allow biofilm formation. Dental blocks were extraorally submitted to a 20% sucrose solution at three different frequencies of exposure (0, 3 and 8 times/day), and to a suspension of amoxicillin/clavulanate potassium (A/CP) or a placebo (P) suspension at an 8-hour time interval application regimen.

In vitro effect of paediatric liquid medicines on deciduous enamel exposed to biofilm.

Objective: This study aimed to assess the in vitro effects of paediatric liquid medicines on deciduous enamel exposed to biofilms.

Methods: Fragments (n = 25) of first primary molars were covered by nail varnish, leaving a 22 mm(2) exposure area. Specimens were fixed in polystyrene plates containing BHI broth media.

Caries preventive effects of xylitol-based candies and lozenges: a systematic review.

Objective: A systematic review of published data was conducted with the aim of assessing the caries preventive effect of consuming xylitol-based candies and lozenges.

Methods: Electronic and hand searches were performed to find clinical trials concerning the consumption of products containing xylitol, published up to November 2009. The studies must have had the following characteristics: (a) a comparison of caries progression in subjects who either did or did not consume candies or lozenges containing xylitol during a minimum follow-up period of 1 year; and (b) a concurrent comparison of the percentage of caries progression according to the World Health Organization criteria.

In vitro alterations in dental enamel exposed to acidic medicines.

Objective: To evaluate the effect of acidic medicines (Klaricid(®), Claritin(®), and Dimetapp(®)) on surface enamel in vitro.

Methods: Enamel blocks (n=104) were randomly distributed into two groups: G1 (pH-cycling simulating physiological oral conditions) and G2 (erosive conditions). Each group was divided into four subgroups, three to be immersed in the medicines and the control in deionized water.

An unusual accident during a primary molar extraction.

Background: Special care must be taken during surgical procedures in children, especially primary tooth extractions. However, despite dentist's effort to perform tooth removal carefully, some accidents may be unavoidable when defective instruments are unknowingly used.

Case Report: This article presents a case of a pediatric dental elevator fracture during a primary mandibular right second molar extraction.

Evaluation of inflammatory response of EDTA, EDTA-T, and citric acid in animal model.

Introduction: The biocompatibility of chelating agents and organic acids have been explained by a variety of methods, and suggestions for use have been based more on clinical observations and physicochemical properties than on biological aspects. The present study aimed to evaluate the inflammatory response of 17% EDTA, 17% EDTA-T, and 10% citric acid in bony defect created in rat jaws.

Methods: Mandibular through and through critical size defects were created bilaterally in 60 rats.

Influence of local factors on cementoenamel junction-alveolar bone crest distance in primary dentition.

Objective: This study illustrated the influence of local factors (dental biofilm, gingival bleeding, probing depth, proximal contact and proximal caries/inadequate restorations) on the cementoenamel junction (CEJ)-alveolar bone crest (ABC) distance in primary canines and molars of healthy children with complete primary dentition.

Study Design: Two hundred and four patients have been examined clinically with regard to biofilm's presence, gingival status, probing depth, proximal contact and dental condition (carious lesions/restorations). Two bitewings of each patient were also taken.

[Perceptions and attitudes among parents and guardians on the use of pediatric medicines and their cariogenic and erosive potential].

The study assesses the perceptions of parents/guardians on the use of pediatric medicines and their cariogenic/erosive potential, interviewing them on the relationship between the use of pediatric medicines and cavities/dental erosion, as well as oral hygiene procedures after the medication. Among the interviewed parents/guardians (n=86), 24 (27.9%) mentioned the sour taste of pediatric medication, 51 (59.

Pediatric bitewing film holder: preschoolers' acceptance and radiographs' diagnostic quality.

Purpose: The purpose of this study was to evaluate a modified bitewing film holder based on preschoolers' acceptance and the diagnostic quality of radiographic images.

Methods: Sixty-six 3- to 5-year-old children were radiographed with the modified device. Acceptance was assessed according to their behavior during the radiographic examination and to their perception of the procedure.

Pediatricians' perceptions of the use of sweetened medications related to oral health.

Objective: To evaluate pediatricians' perceptions and attitudes about the use of liquid pediatric medicines and their relationship with dental caries and dental erosion.

Study Design: A cross sectional study was conducted. Data was collected by questionnaires handed out in hospitals, medical clinics and offices.

Bruxism in children: a warning sign for psychological problems.

Bruxism is nonfunctional clenching or grinding of the teeth. It is a destructive habit that may result in tooth wear. Although research on bruxism is extensive, its etiology remains debatable.

Free sugar concentration and pH of paediatric medicines in Brazil.

Objective: This study aimed to determine free sugar concentration and pH of paediatric syrup medicines. Setting Ten paediatric syrup medicines most frequently prescribed in urban centres in Brazil were randomly chosen to be tested.

Outcome Measures: Three different bottles from each type of syrup medicine were analysed (n = 30).

Alveolar bone loss in the primary dentition: state of the art.

Alveolar bone loss has been reported in primary teeth of healthy young children with a variable prevalence. This study aimed to review the literature on alveolar bone loss in the primary teeth of children without systemic diseases and to discuss the controversies with regard to the prevalence of this pathology in the primary dentition.

Pediatricians' perception about the use of antibiotics and dental caries--a preliminary study.

Objectives: This study aimed to evaluate pediatricians' perception about the use of antibiotics and dental caries.

Methods: One hundred pretested questionnaires containing open and closed questions were distributed to pediatricians from public hospitals in Rio de Janeiro, Brazil.

Results: The response rate was 60 percent.
