RESUMEN
Data on long term survival and tooth stability after regenerative endodontic treatment are missing. The purpose of the present report is to describe regenerative endodontic treatment of a permanent mandibular canine with extensive coronal hypoplasia, immature root, and a periapical radiolucency. The regenerative endodontic treatment was initiated by irrigation of the root canal, followed by three weeks of triple antibiotic paste dressing and the creation of a blood clot scaffold covered with mineral trioxide aggregate. A one year clinical and radiographic follow-up demonstrated healing of the periapical radiolucency and the tooth remained stable and sound for almost thirteen years post treatment.

OBJECTIVE: The purpose of this study was to determine if gas tension and acidity levels could serve as biomarkers of pulp inflammatory status in primary dentition. STUDY DESIGN: The present study evaluated acidity level and blood partial pressures of O2 and CO2 collected from vital pulp chambers of 84 primary molars with deep carious lesions encroaching the pulp. Teeth were treated with pulpotomy or pulpectomy based on clinical judgement. Pulpectomy was performed when symptoms of spontaneous pain, difficulty in obtaining hemostasis and/or dark purple blood were present. Using a glass capillary, pulp chamber bleeding was collected and within ten minutes a neonate Astrup test was performed to determine blood gas module pH, pCO2, and pO2. RESULTS: Eighty-four children with one affected tooth participated in the study (37 girls and 47 boys). Age ranged between 3.5 to 9-years (average: 5.3 years). Seventy-one (84%) were treated with the aid of inhalation analgesia, conscious sedation or general anesthesia. Pulpotomy was performed on 58 teeth (69%). Teeth undergoing pulpectomy revealed significant higher level of CO2 partial pressure (P= 0.002). Acidity level values (pH) were also lower but none significantly in teeth with pulpectomy (P= 0.137). CONCLUSIONS: Higher pCO2 levels was found in pulps needing pulpectomy.

Objective: The present study compared the mineral contents of enamel and dentin of primary teeth from children exposed to desalinated water with those from children drinking ground water. Study design: The study comprised of two groups of teeth, seven primary teeth from children living in areas supplied exclusively with desalinated water and seven primary teeth from children that have been exposed solely to ground water from in-utero until the teeth were either extracted or naturally shed. Mineral content of three tooth regions was determined by scanning electron microscopy with an energy dispersive X-ray spectrometer (EDS). The main ion content of each region was calculated. Results: Children exposed to ground water presented higher levels of magnesium in pre- and post- natal enamel than children living in areas supplied exclusively with desalinated water but without significant differences. The same was found for calcium levels. Excluding post-natal enamel calcium level (of borderline statistical significance), no significant differences were found in magnesium and calcium levels of primary teeth enamel and dentin of children exposed to desalinated water in comparison to children exposed to ground water. Conclusion: Mineral content of enamel and dentin in primary teeth is not affected by consuming desalinated water.

Extracting primary canine tooth buds is a ritual ceremony that prevails in some African countries. This procedure is considered infant oral mutilation (IOM) and may damage the permanent successor and adjacent primary and permanent teeth, resulting in dysplastic or deformed teeth. The purpose of this report was to describe regenerative endodontic treatment of a permanent mandibular canine with extensive coronal hypoplasia, immature root, and a periapical radiolucency following damage to the permanent canine that was probably a result of infant oral mutilation. Regenerative endodontic treatment was initiated by irrigating the root canal, followed by applying triple antibiotic paste dressing over three weeks and creating a blood clot scaffold covered with mineral trioxide aggregate. A 4-year clinical and radiographic follow-up demonstrated healing of the periapical radiolucency. This treatment may serve as a substitute for traditional apexification with calcium hydroxide or creation of an artificial apical barrier with mineral trioxide aggregate.

OBJECTIVES: Attention deficit hyperactivity disorder (ADHD) is a childhood neurological disorder. Studies have shown that children with ADHD are more prone to caries than those without. The study investigated children diagnosed with ADHD, both with and without pharmacological intervention, and the following: DMFT\dmft, plaque index (PI), mutans streptococci (MS) levels, lactobacilli (LB) levels, salivary flow, salivary buffer capacity, oral hygiene, and diet. STUDY DESIGN: DMFT/dmft index, PI, MS and LB levels, salivary flow, and salivary buffer capacity were examined in three groups of children: ADHD1-diagnosed with ADHD with no pharmacological intervention (N = 31), ADHD2-treated with medications for ADHD (N = 30), and a healthy control group (N = 30). Diet and oral health habits were assessed through questionnaires completed by parents. RESULTS: There were no differences in the DMFT/dmft index, MS and LB counts, salivary buffer capacity, and parent reported diet and oral health behavior between the three groups. Children with ADHD demonstrated a higher plaque index. CONCLUSIONS: Although children with ADHD did not report different diet and oral health behavior from children without ADHD, this group had significantly higher levels of plaque than the control group, which combined with hyposalivation may be a risk factor for caries at an older age. CLINICAL RELEVANCE: Medicated and non-medicated ADHD children were similar to control children in their caries rate, MS and LB counts, salivary buffer capacity, and diet and oral health behavior. They differed in the amount of plaque found on their teeth. As a group, ADHD children demonstrated hyposalivation compared with the control.

BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is a childhood neurological disorder that presents in 3-7% of school-age children. Studies have shown that children, adolescents and young adults with ADHD are more prone to caries than those without. AIM: The study investigated a possible relationship between the oral health status of children, adolescents and young adults diagnosed with ADHD, both with and without pharmacological intervention, and the following: salivary flow rate, oral mucosal pH, plaque index (PI), oral hygiene and dietary behaviour. STUDY DESIGN: DMFT/dmft index (D;d-Decay, M;m-Missing; F;f-Filled,T;t-teeth), plaque index, oral mucosal pH and unstimulated whole salivary flow (USF) were examined in three groups of children, adolescents and young adults: those diagnosed with ADHD with no pharmacological intervention (N=31), those treated with medications for ADHD (N=30), and a healthy control group (N=30). Diet and oral health habits were assessed by means of questionnaires completed by parents. RESULTS: Mean USF values were 0.72, 0.85 and 1.13 ml/min for participants with ADHD and without medication, with ADHD and with medication, and without ADHD, respectively (p=0.016). There were no differences in the DMFT/dmft index and in parent reported diet and oral health behaviour between the three groups. Children with ADHD demonstrated a statistically significant higher plaque index (p<0.05). CONCLUSIONS: The ADHD group, with or without pharmacological intervention, showed higher plaque index and lower USF, but no difference in DMFT/dmft. The ADHD group did not differ from the non-ADHD group in their diet or oral health behaviour as assessed by parent reports.
