The purpose of this report is to present the case of a 17-year-old girl diagnosed with cyclic neutropenia (CN), who had undergone six months of treatment with zoledronate three years before. She sought treatment for extreme mobility of the mandibular left lateral incisor, canine and first premolar that had been present for one month. Clinical features included calculus, severe gingival recession and mandibular bone exposure. Panoramic radiographs and cone beam computed tomography confirmed bone sequestration. Conservative treatment comprising antibiotic therapy, use of perio- dontal instrumentation and a hyperbaric chamber proved unsatisfactory. An unfavor- able evolution was confirmed by the presence of bone sequestration that required bone removal, together with the teeth located in the block of the detached bone. The diagnosis was osteonecrosis of the jaw. The patient presented moderate periodontal involvement associated with CN; therefore, periodontitis was unlikely to have been the main factor triggering the local and systemic complications.>.

Early loss of teeth in the premaxilla can limit future restorative options. One solution is replacement using autotransplantation. This surgical technique can be optimized by using 3D-printed models to aid in planning and improving the prognosis. The pur- pose of this case report is to describe the autotransplantation of a premolar into the site of a hopeless maxillary incisor in a 12-year-old male with bilateral cleft lip and palate who had missed previous bone grafting opportunities, using a 3D-printed ana- logue. After a 25-month-follow-up, the autotransplantation continued to be successful and the patient was able to progress with other restorative procedures.

Juvenile trabecular ossifying fibroma (JTOF) is a rare, aggressive neoplasm primarily affecting children. The purpose of this case report is to describe an extensive mandibular JTOF in a 10-year-old girl who presented with facial pain and swelling. Radiographic imaging revealed a large, well-defined radiolucency with cortical perforation. Histo- pathological examination confirmed JTOF, characterized by cellular fibroblastic tissue and woven bone trabeculae. Due to the aggressive nature of the fibroma, the patient underwent a right hemimandibulectomy. This report highlights the critical need for early diagnosis, accurate histopathological assessment and long-term follow-up to man- age JTOF effectively and prevent severe facial deformities.

Purpose: To evaluate the bonding effectiveness of a new universal adhesive system compared to its predecessor on carious primary dentin using the etch-and-rinse and self-etch techniques.

Methods: Twenty human primary molars were subjected to artificial induction of carious dentin and then randomized into four experimental groups according to universal adhesive (Scotchbond Universal Plus, SBU Plus and Scotchbond Universal-SBU) and bonding techniques (etch-and-rinse and self-etch). The adhesives were applied according to the manufacturer's instructions and the starch tube molds were filled with a flowable composite resin. Bond strength was determined using a testing machine and the data were analyzed using two-way analysis of variance. All specimens tested were assessed for failure pattern classification.

Results: No significant differences in bond strength values were observed when com- paring universal adhesive systems (P =0.83), etching technique (P =0.34) or the cross- interaction adhesive system versus etching technique (P =0.96).

Conclusion: Regardless of the bonding technique, SBU Plus showed similar bond strength compared to its predecessor when applied to carious dentin of primary molars.

The quest for an esthetically pleasing smile is a key driver in seeking dental interventions aimed at achieving a more balanced and harmonious appearance. The purpose of this report is to discuss the restoration of conical lateral incisors in an 11-year-old patient. The treatment approach employed direct composite resin restorations associated with the Digital Smile Design (DSD) technology. The use of composite resins is the technique of choice for re-anatomizing conical teeth due to the material's versatility and low cost. In this case, the technique associated with the digital workflow resulted in the efficacy of esthetic restorations. DSD contributes to greater predictability of dental treatment, comfort, safety and efficiency.

Purpose: To investigate the oral health-related quality of life (OHRQoL) of young children in a randomized clinical trial (RCT) of silver diammine fluoride (SDF) and five percent sodium fluoride varnish (NaFV) to manage early childhood caries (ECC). Methods: Children younger than 72 months of age with active dentinal caries lesions (ICDAS 5 or 6) in primary teeth received two applications of 38 percent SDF and five percent NaFV as part of an RCT testing three different frequency regimes (one, four, and six months apart). The Early Childhood Oral Health Impact Scale (ECOHIS) questionnaire was completed at three study visits. Statistical analyses included descrip- tive and parametric methods. A P -value of ≤0.05 was significant. Results: Eighty-two children (58.5 percent male) were recruited with a mean age of 44.3±14.2 months. Significant improvement in total ECOHIS scores for all children was observed following treatment (baseline mean scores=4.52±4.77 versus third visit mean scores=3.19±3.78, P =0.01) and family impact scores for all children (base- line mean scores=3.00±2.98 versus third visit mean scores=1.68±2.01, P ≤0.001). However, no significant change in the mean child impact score was observed among all the children ( P =0.97). The parental distress and family function domains showed the most improvement with SDF treatment. No significant ECOHIS score differences were found among the three frequency groups across visits. Conclusions: Children showed better OHRQoL after applying 38 percent SDF and five percent NaFV. No significant differences were found between treatment groups. SDF is a viable non-restorative option for managing ECC as it has a positive effect on OHRQoL.

Purpose: To assess the effectiveness of Biodentine^™ (BD), mineral trioxide aggregate (MTA) and ferric sulfate (FS) as pulpotomy agents in primary molars and evaluate the impact of behavior guidance strategies on pulpotomy success.Methods: In this retrospective cross-sectional study, data from 374 cases (50.5 percent male, aged two to 10 years) undergoing 469 pulpotomies at a university pediatric clinic between April 1, 2016 and January 1, 2020 were analyzed. Clinical and radiographic outcomes were evaluated by two calibrated examiners using validated criteria. Statistical analysis included descriptive statistics, logistic regression (P <0.05), Kaplan-Meier survival curves and Cox proportional hazard models, with inter- and intra-examiner reliability confirmed by Cohen's Kappa. Results: Among the materials, BD and MTA showed the highest clinical (98.5 percent and 97.9 percent, respectively) and radiographic (95.2 percent and 93.6 percent, respectively) success, significantly outperforming FS (88.9 percent and 80.9 percent, respectively). Pulpotomy failures were notably higher with the use of protective stabilization (P =0.002), while treatment under general anesthesia and good patient cooperation were associated with better outcomes. Conclusions: BD and MTA demonstrated superior effectiveness over FS for primary molar pulpotomies. The success of pulpotomy is significantly influenced by behavior guidance techniques, with less restrictive methods correlating with improved outcomes.

Trichothiodystrophy (TTD) is a rare genetic disorder with a high mortality rate among pediatric patients, primarily as a result of related infections. Its defining clinical feature is brittle, dry hair, with broken hair shafts revealing "tiger-tail banding". Other common characteristics include photosensitivity, scaly skin and stunted growth. The disorder's rarity and variety of symptoms pose diagnostic challenges, yet early diagnosis and treatment can improve a patient's overall health and quality of life. The purpose of this report is to describe the case of an underweight five-year-old boy with brittle hair and scaly skin who presented to an emergency room with an active odontogenic infection and was incidentally diagnosed with TTD following genetic testing. This case illustrates the importance of evaluating patients comprehensively, while addressing their chief complaint. It also showcases the importance of involving providers across health professions in diagnosing and managing TTD and other genetic disorders in pediatric patients.
