Dental considerations and recommendations in Eisenmenger syndrome: A report of an unusual paediatric case.

BACKGROUND: Eisenmenger syndrome (ES) is a heart cyanotic condition characterised by elevated pulmonary vascular resistance and an intra-cardiac right-to-left shunting of blood through a systemic-to-pulmonary circulation connection. Affected children usually exhibit severe hypoxia, clubbing of fingers/toes, haemoptysis, anaemia, and organ damage. CASE REPORT: During autumn 2015, the patient and her parents arrived at the paediatric dentistry clinic. The patient presented with the main complaint of generalised inflamed gingival tissues, severely protruded upper incisors, and evident abnormal mouth breathing. TREATMENT: This was performed under local analgesia, rubber-dam isolation, and antimicrobial prophylaxis with amoxicillin (50 mg/kg). The patient's parents agreed to the treatment plan through a signed informed consent. This treatment consisted of the placement of pit and fissure sealants on the four permanent first molars (which included enamel preparation with fissurotomy burs), in-depth gingiva/dental frequent cleanings, local fluoride varnish applications, and an exhaustive programme of at-home oral hygiene (brushing, flossing, and chlorhexidine mouth rinses), including adequate nutrition. Gingivoplasty surgery to remove residual enlarged tissues was indicated for the near future. FOLLOW-UP: The child did not return to the clinic. When contacted, the parents reported that their daughter's systemic condition worsened significantly. She was confined to a bed at home under palliative care, with a life-span expectation of only a few months. CONCLUSION: Comprehensive dental care of children with ES requires careful consideration of their medical condition, and dental care delivery should be coordinated with the paediatric cardiologist. General analgesia should be considered only in strictly selected cases, due to the high peri-operative mortality reported.

Fundamentals in Biostatistics for Research in Pediatric Dentistry: Part I - Basic Concepts.

The purpose of this report was to provide the reader with some basic concepts in order to better understand the significance and reliability of the results of any article on Pediatric Dentistry. Currently, Pediatric Dentists need the best evidence available in the literature on which to base their diagnoses and treatment decisions for the children's oral care. Basic understanding of Biostatistics plays an important role during the entire Evidence-Based Dentistry (EBD) process. This report describes Biostatistics fundamentals in order to introduce the basic concepts used in statistics, such as summary measures, estimation, hypothesis testing, effect size, level of significance, p value, confidence intervals, etc., which are available to Pediatric Dentists interested in reading or designing original clinical or epidemiological studies.

Probiotics and their effect on oral bacteria count in children: a pilot study.

AIM: To assess the effect of the daily ingestion of a mixture of probiotics on the amount of Streptococcus mutans in the oral cavity of preschool-age patients with a high risk of caries. MATERIALS AND METHODS: Forty patients, aged between 4 and 6 years, with a high risk of dental caries were included in this pilot study. Patients were randomly assigned to two study groups: the Experimental Group (A) included patients who brushed their teeth and used fluoridated toothpaste in addition to consuming probiotics daily, and the Control Group (B) inclused patients who brushed their teeth and used fluoridated toothpaste but did not consume probiotics. Using the CariScreen, the microorganism count was determined at different times: baseline, 7, 14, 21 and 30 days. To identify the differences between both groups, a Mann-Whitney U test was performed, with a significance level of 0.05. RESULTS: It was observed that both groups showed similar microbial counts at the beginning of the trial (p>0.05), and a significant decrease in the count at the end of the study was found in the experimental group (p<0.05) 15 days after suspending ingestion. CONCLUSION: We found a significant reduction of RLU values in preschool children who ingested the tested probiotics in relation to the baseline values and 15 days after ceasing consumption.
