Background/Objectives: Gingivitis is one of the most prevalent inflammatory conditions in pediatric populations and represents a significant oral health burden worldwide. In addition to conventional approaches, emerging adjunctive therapies such as low-level laser therapy (LLLT), also known as photobiomodulation, have gained increasing attention. This review aims to evaluate current evidence regarding the clinical relevance and potential healthcare implications of LLLT in the management of gingival inflammation in children and adolescents. Methods: A structured narrative literature review was conducted, including experimental, animal, and clinical studies published between 2005 and 2025. Study selection and screening were performed independently by two reviewers. Methodological characteristics of the included pediatric clinical studies were qualitatively assessed, focusing on randomization, blinding, follow-up reporting, and adverse event monitoring. Results: Experimental studies demonstrate that LLLT enhances gingival cell proliferation and modulates inflammatory responses, while antimicrobial effects remain inconsistent. Animal studies indicate reductions in gingival inflammation and alveolar bone loss when LLLT is used adjunctively with conventional therapy. Clinical studies in pediatric populations report improvements in gingival indices and periodontal treatment needs, with no adverse effects observed. Conclusions: LLLT appears to be a safe, non-invasive adjunctive therapy with potential to improve oral health outcomes in pediatric populations. Its clinical applicability and high patient acceptability support its potential integration into broader oral healthcare strategies. However, further well-designed clinical trials with standardized protocols and long-term follow-up are required.

Aim and objectives: to assess the changes in speed of the apical pathological root resorption and its causes in a group of Romanian children from Bucharest treated at the Paediatric Dentistry Department. Material and methods: The retrospective study was carried out on the OPG of 94 Romanian children aged between 3.5 and 13.58 years, mean age 8.00±0.20 years and on 1137 primary teeth. Results: The apical root resorption represented 93.1% from the teeth with external root resorption. Early root resorption was present in 15.4%, while the late root resorption in 6.5%, of the teeth. Pulpal and periapical infection were the most encountered (8%) causes of the accelerated root resorption. Conclusions: Accelerated root resorption was the most common change in the rate of root consumption recorded in primary teeth and its main cause being the pulpal complications of the untreated caries and trauma.

The aim of this study was the evaluation of the success rate of 3 pulp capping treatment techniques and to compare the results obtained in primary (PM) and first permanent molars (FPM). Material and methods: In this retrospective study we collected data from 194 medical records; 330 PM and immature FPM treated by pulp cappings were analyzed. Results: The success rate of pulp capping treatments in PM was 64.5%, while for FPM this counted for 96.6%. The means of survival time in PM were: indirect pulp capping (IPC) – 59.24±3.92 months, stepwise (SW) – 32.55±3.19 months, and direct pulp capping (DPC) – 32.35±6.6 months; for FPM: IPC – 102.47±3.07 months, SW – 57.31±5.18 months, and DPC – 49.46±17.07 months. When we compared the findings between dentitions, we observed that IPC and SW techniques had superior results in FPM than in PM. Conclusions: Based on our results, IPC and SW methods seem to be better choices in terms of preserving pulp vitality in both PM and FPM. Overall, FPM vital therapy was more successful than that of PM.
