AimsCerebral palsy (CP) is a chronic, nonprogressive disorder affecting movement, posture, and tone, caused by injuries in the central nervous system during the early stages of life. Patients with CP have swallowing disorders, which make oral feeding difficult and necessitate the use of external feeding devices. The objective of this research was to study the oral health status of pediatric patients affected with CP fed by either oral or enteral route.MethodsA cross‐sectional observational clinical study of the oral health of two groups of patients with CP, fed either orally or enterally (via percutaneous endoscopic gastrostomy, PEG).ResultsPatients fed by enteral route via PEG presented lower caries scores (DMFT: PEG: 1.09, non‐PEG: 2.81) and higher percentages of supragingival dental calculus than the oral feeding group (PEG: 86%, non‐PEG: 57.6%).ConclusionOral health status differed in pediatric patients with CP fed enterally via PEG and those fed orally. Specific preventive measures in both groups will be required to minimize the risk of complications.

Background In medicine and dentistry, 3D technology allows the virtual planning and printing of surgical replicas of anatomical structures that can facilitate certain transplant procedures. In dentistry, 3D technology is useful in autogenous tooth transplantation. Case presentation We present a clinical case of an ectopic mandibular second premolar, describing the preoperative planning with dental replicas and the autotransplantation surgery. 3D prints of the surgical replica of the tooth to be transplanted was made using an Objet30 Prime® Printer, PolyJet. Clinical controls performed at 3, 6 and 12 months indicated the satisfactory evolution of the transplanted tooth. Conclusion 3D additive manufacturing technology allows the preparation of a new recipient socket with the aid of a surgical replica of the tooth to be transplanted, thus minimizing handling and extraoral time.

Introduction: Prader-Willi Syndrome (PWS) is a genetic disorder caused by the lack of expression of certain paternal genes located on chromosome 15q11-q13. This anomaly causes cognitive, neurological and endocrine abnormalities, among which one of the most important is hyperphagia. The aim of this study was to assess the oral health of children with PWA and to establish preventive criteria. Results: Thirty patients with PWS (mean age 10.2 years) and 30 age-and gender-matched controls were included in the study. Twenty-six patients with PWS(86.6%) followed dietary treatment prescribed by their endocrinologist. Individuals with PWS had a mean caries index of 53.3% and Decayed Missing Filled teeth (DMFT) index 2.5, and 53.3% had gingivitis, in the control group the respective figures were 43.3%, 0.93, and 60%. Only the DMFT index (p 0.017) presented significant differences. Regarding stimulated salivary secretion, patients with PWS presented a mean of 0.475 ml/min with a pH of 6.15, while controls presented a mean of 0.848 ml/min with a pH of 7.53; the differences between the groups were statistically significant in both cases (p 0.032 and p 0.0001 respectively). The population with PWS presented a higher plaque index (> 2) than their healthy peers, but the differences were not significant. Conclusion: Pediatric patients with Prader-Willi syndrome have an increased risk of caries and gingivitis. The children with this syndrome have a decreased salivary flow and a more acidic salivary pH. In these patients, dental care is an essential part of their multidisciplinary medical treatment.
