Background/Objectives: Dental anxiety represents a major challenge in paediatric dentistry and is a frequent cause of non-cooperative behaviour during dental treatment. Nitrous oxide/oxygen inhalation conscious sedation is widely used to reduce anxiety in children, while audiovisual distraction is a non-pharmacological behavioural technique aimed at diverting attention from stressful stimuli. Evidence regarding the combined effect of these two approaches during dental treatment is still limited. Methods: This randomized crossover clinical trial included 25 paediatric patients aged 4–7 years with dental anxiety and previous failed attempts at conventional dental treatment. Each child underwent two dental treatment sessions under nitrous oxide/oxygen conscious sedation, one with and one without audiovisual distraction. Anxiety and behaviour were assessed using the Modified Venham Scale and the Facial Image Scale (FIS). Vital parameters were recorded before, during, and after sedation. Results: A significant reduction in heart rate over time was observed in both groups (p < 0.05). In children aged 4–5 years, the combined audiovisual distraction and conscious sedation approach was associated with significantly lower heart rate values compared to conscious sedation alone (p < 0.05). No significant differences were found between the two approaches for behavioural scores assessed by the Venham and FIS scales. Conclusions: Although behavioural scores did not differ significantly, audiovisual distraction contributed to greater physiological stability, particularly in terms of heart rate control. This no-pharmacological approach may complement the pharmacological effects of nitrous oxide sedation by enhancing the overall sense of relaxation and comfort during dental care.

Introduction: In clinical practice, the presence of abnormal physiological root resorption frequently results in the retention of deciduous teeth. Also, unilateral mastication may contribute to the altered physiological process of root resorption. This delayed exfoliation and retention of deciduous teeth may compromise the integrity of adjacent soft tissue. In recent years, ozone therapy can be considered a promising strategy in accelerating healing and reducing pain in both traumatic and autoimmune ulcers. Case Presentation: This case report describes a 12 year-old male patient with localized damaged gingival tissue resulting from chronic trauma due to the retention of a deciduous tooth. Following the application of gaseous ozone therapy, complete mucosal healing was achieved. Conclusions: This case supports the potential of ozone therapy in paediatric soft tissue management.
