Abstract

BACKGROUND: Molar incisor hypomineralisation (MIH) is frequently associated with hypersensitivity, dental anxiety and reduced efficacy of local anaesthesia, complicating pain control during dental treatment in children. AIM: To evaluate, based exclusively on randomised controlled trials (RCTs), the effectiveness of different local anaesthetic techniques, agents and adjunctive interventions in reducing pain during dental treatment of MIH-affected teeth in children. METHODS: A systematic review was conducted following PRISMA 2020 guidelines and registered in PROSPERO (CRD420251150485). MEDLINE, Cochrane Central, ScienceDirect, SCOPUS, EBSCO, and LILACS were searched up to September 2025. Eligible studies were RCTs involving children and adolescents (6 - 18 years-of-age) with MIH, assessing pain outcomes during dental procedures. Risk of bias was assessed using the Cochrane RoB 2 tool, and certainty of evidence was evaluated using the GRADE approach. RESULTS: Eight RCTs were included. Low-certainty evidence suggested that intraosseous anaesthesia and 4% articaine may reduce intra-operative pain compared with conventional techniques or 2% lidocaine. Adjunctive cryotherapy and pre-emptive ibuprofen showed potential benefits, but evidence was of very low certainty and limited to single trials. Findings for photobiomodulation were inconsistent across studies. Most trials were judged to be at high risk of bias, primarily due to lack of blinding and reliance on subjective pain outcomes. CONCLUSION: Current evidence supporting specific pain management strategies for MIH-affected teeth is limited and of low certainty. Whilst 4% articaine and intraosseous anaesthesia appear promising, well-designed, adequately powered RCTs with standardised pain outcomes are required to inform robust clinical recommendations.

Effect of Various Types of Remineralizing Agents on the Remineralization of Mild and Moderate Defects Caused by Molar-Incisor Hypomineralization in Mexican Schoolchildren: A 12-month Follow-up Randomized Clinical Trial.

PURPOSE: Using Laser-Induced Fluorescence (LIF), this study aimed to evaluate the effect of three remineralizing agents on permanent molars and incisors with both mild and moderate Molar-Incisor Hypomineralization (MIH) in 8-to-12-year-old Mexican schoolchildren. MATERIALS AND METHODS: In this randomized clinical trial, 104 children were selected to participate and then divided randomly into four groups: Group I: control, Oral-B kids (toothpaste); Group II: Fluor Protector (varnish); Group III: Clinpro White Varnish; and Group IV: MI Paste (CCP-ACP). Both varnishes were applied once every four weeks for twelve months for each group. Remineralization was evaluated by LIF at intervals of 1, 3, 6, 9, and 12 months. Paired-sample t-tests and repeated-measures ANOVA were performed, while the Greenhouse-Geisser correction was used to evaluate sphericity. RESULTS: The three test agents used increased the level of remineralization observed at the site of mild and moderate MIH defects over the course of twelve months (p0.001). A similar decrease in average LIF values was observed across the three treatment groups. CONCLUSIONS: The use of both fluoride varnishes and the CPP-ACP toothpaste was observed to promote the remineralization of both mild and moderate MIH defects.

Clinical effectiveness of transversus abdominis plane block versus local anaesthesia wound infiltration for postoperative pain relief after laparoscopic appendicectomy in children: A multicentre, double-blind, randomised, controlled phase III trial.

BACKGROUND: Postoperative pain relief after laparoscopic appendicectomy in children provided by transversus abdominis plane (TAP) block and local anaesthesia wound infiltration (LAWI) of trocar insertion sites has never been compared. OBJECTIVE: To investigate whether TAP block could decrease postoperative opioid requirements after laparoscopic appendicectomy in children compared with LAWI. DESIGN: Multicentre, double-blind, phase III randomised trial. SETTING: Two tertiary paediatric surgery centres. PATIENTS: Children aged 3 to 15 years admitted for laparoscopic appendicectomy. MAIN OUTCOME MEASURES: The primary outcome was the total dose of nalbuphine delivered within 24 h after surgery. Secondary outcomes were the Face Legs Activity Cry Consolability (FLACC) scale values at 1, 2, 6, 12 and 24 h, the time from levobupivacaine injection to the first dose of nalbuphine, and the time from the end of surgery to the first mobilisation. Patients received either ultrasound-guided TAP block (TAP group) or LAWI of trocar insertion sites (infiltration group) with 0.6 ml kg -1 of levobupivacaine 2.5 mg ml -1 , combined with standardised systemic multimodal analgesia including paracetamol, ketoprofen, phloroglucinol and nalbuphine. RESULTS: Forty-six and 50 patients were analysed in the TAP and infiltration groups, respectively [age: 10 [7 to 12] versus 10 [8 to 12] years; females: 16 (35%) versus 25 (50%); duration of surgery: 71 [64 to 90] versus 69 [56 to 89] min]. The primary outcome (total nalbuphine dose) was 0.2 [0.0 to 0.2] and 0.2 [0.0 to 0.2] mg kg -1 in the TAP and infiltration groups, respectively ( P  = 0.95). FLACC scale values did not significantly differ between the two groups ( P  = 0.78). Time to the first dose of nalbuphine or to first mobilisation was not significantly different between groups ( P value for log-rank test = 0.095 and 0.18, respectively). CONCLUSION: TAP block does not appear to provide a greater opioid-sparing effect than LAWI of trocar insertion sites after laparoscopic appendicectomy in children, when combined with systemic multimodal analgesia including nonsteroidal anti-inflammatory drugs. TRIAL REGISTRATION: ClinicalTrials.gov NCT04969133.

Molecular mechanisms of neuroendocrine regulation of molting in the Chinese mitten crab (Eriocheir sinensis): A transcriptomic analysis based on eyestalk ablation model.

Molting disability severely restricts the sustainable aquaculture of the Chinese mitten crab, yet the neuroendocrine mechanisms coordinating physiological responses remain poorly understood. Using unilateral eyestalk ablation to remove the primary source of molt-inhibiting hormone (MIH), we performed time-resolved transcriptomic profiling of the thoracic ganglion at 24 h (early premolt) and 48 h (ecdysis) post-ablation. We identified 2825 differentially expressed genes and uncovered a biphasic molecular response. At 24 h, the thoracic ganglion activates pathways associated with neuromuscular adaptation, oxidative stress, and cardiac muscle contraction. Notably, the arachidonic acid metabolism pathway is selectively rewired: cytochrome P450 ω-hydroxylases (CYP2J2, CYP4V2) are upregulated, while competing branches (epoxide hydrolase, cyclooxygenase) are suppressed, promoting local synthesis of the potent vasoconstrictor 20-HETE within the thoracic ganglion. This enzymatic switch provides a mechanistic link between MIH withdrawal and the local generation of elevated hemolymph pressure required for molting. By 48 h, the transcriptional program shifts toward chitin-based extracellular matrix remodeling, glycosphingolipid biosynthesis, and synaptic reorganization. Collectively, our findings redefine the thoracic ganglion as an active neuroendocrine integrator that translates reduced MIH signaling into phased physiological outputs, revealing a "neuro-endocrine-hemolymph pressure" regulatory axis. This study provides novel molecular targets (e.g., CYP2J2, CHS1, UGCG) for mitigating molting disability in E. sinensis aquaculture.
