Dental autotransplantation refers to 'transplantation of an unerupted or erupted tooth in the same individual, from one site to another extraction site or a new surgically prepared socket'. 1 It has various advantages, such as conferring a satisfactory gingival outcome among patients, 2 facilitating the growth of alveolar bone 3 and potential for regeneration of normal periodontal ligament (PDL) that allows for proprioception and orthodontic movement. 4 The success and survival rate of autotransplantation is over 85%, with donor teeth with open apices having lower complication rates than those with complete root development. 5 As such, autotransplantation is considered a viable treatment option when applied within a comprehensive plan by an interdisciplinary dental team to replace missing teeth due to traumatic dental injury (TDI) 6 or manage hypodontia 7 among children and adolescents.In recent years, methods to further improve the success and survival of autotransplants have been investigated. This involves presurgical preparation, such as using cone beam computed tomography (CBCT) for surgical simulation and developing three-dimensional (3D)-printed donor teeth replicas or surgical stents prior to the procedure. 8 The former allows clinicians to evaluate the adequacy of the prepared socket before carrying out the actual transplant, which minimises trauma and extra-alveolar time to the donor teeth while

Silver-modified atraumatic restorative technique (SMART) is an emerging restorative technique; however, the effect of silver diamine fluoride (SDF) application on the bond strength of glass ionomer cement (GIC) is unknown. This study aimed to determine if SDF application to sound and artificial caries-affected dentin (ACAD) immediately prior to GIC restoration affected microtensile bond strength (µTBS). Caries was induced on extracted molars using a pH-cycling protocol that was validated against natural caries (similar µTBS). Dentin surfaces were treated with 38% SDF, control groups with de-ionized water and immediately restored. Beamshaped specimens were sectioned and subjected to tensile forces for µTBS determination. Two hundred and eighty-seven specimens from 40 teeth were tested. SDF application significantly (p<0.001) reduced µTBS in sound dentin (19.00±8.20 MPa vs. 14.60±6.68 MPa), while no difference was found in ACAD. No difference was found in failure mode among groups. For SMART, SDF application on sound dentin before immediate GIC restoration may decrease bond strength.

Aim To explore oral health-related knowledge, abilities, attitudes, practices, and barriers of pediatric oncology nurses at an Asian children’s hospital. Methods A cross-sectional study was conducted via a self-administered anonymized questionnaire. Data was analyzed to summarize knowledge, confidence, and practice behaviors. Results All sixty-three pediatric oncology nurses responded. Fifteen participants had >80% of the knowledge questions correct. Majority (97.3%) agreed on their roles in helping patients maintain their oral health. However, 75.8% of participants felt need for training in giving oral health advice. Notably, 74.6% checked patients’ mouths at least once daily but only 57.1% felt adequately trained. Though a high proportion (>90%) of nurses felt confident to assist with oral care, only 65% would assist patients to do so; “Uncooperative patient” was the major barrier reported. Discussion Nurses have high general awareness of importance of oral health, but had incomplete knowledge. Compared to previous studies, most (90.5%) did not find performing oral care unpleasant but other barriers might have hindered actual oral care practice. Conclusion Nurses were motivated to assist in oral care of children with cancer but sometimes felt ill-equipped. Updated national and institution guidelines, didactic and hands-on training, and implementation of practical support could be considered.

Introduction Facial nerve palsy is a rare, but known complication resulting from local anaesthesia (LA) infiltration during dental surgery. Its incidence is reported to be 1–1.1%, with short or long-term effects. Case Report A 6 years old well child underwent elective dental rehabilitation under general anaesthesia. For extractions, he received LA infiltration to the anterior part of the hard palate. In the immediate post-operative period, he presented with left sided facial droop and uvula deviation to the left with no hoarseness of voice or ptosis. His neurological symptoms resolved within 3 h of the administration of LA. He was reviewed on the same day by the paediatric neurologist. No further investigations were required. He was discharged well the next day. Conclusion Transient facial nerve palsy and uvula deviation, while rare, can occur after a dental procedure. For paediatric patients, the neurologist’s input helps with parental assurance.
