RESUMO
PURPOSE: The current study compares articaine 4% with lidocaine 2% in terms of injection pain and effectiveness of anesthesia when treating permanent mandibular first molars (PMFMs) affected by molar incisor hypomineralization (MIH). In addition to comparing the complications of local anesthesia for both solutions. METHODS: The sample included 20 children. Each child was randomly assigned to either articaine 4% or lidocaine 2% in their first session with the other solution being used at the subsequent session. Injection pain and the effectiveness of anesthesia were assessed using the Wong-Baker Faces® Pain Rating Scale and the Face, Legs, Activity, Cry, and Consolability (FLACC) scale. Parents were asked to report any complications of local anesthesia. The Wilcoxon-matched pairs signed-rank test was used to analyze the data. RESULTS: Patients experienced greater pain when receiving articaine 4% injections according to both scales, differences were statistically significant when using the Wong-Baker Faces® Pain Rating scale (p < 0.05). Whereas, the FLACC scale did not show such differences (P > 0.05). Although there were no significant differences between the two solutions regarding the effectiveness of local anesthesia according to both scales (P > 0.05), articaine 4% was clinically found to be more effective than lidocaine 2%. No complications of local anesthesia were reported. CONCLUSIONS: Articaine 4% injection was more painful than lidocaine 2%. However, both solutions were effective in anesthetizing PMFMs affected by MIH and without anesthetic complications in the studied sample. TRIAL REGISTRATION: Clinical trial, NCT05200884, ( https://clinicaltrials.gov/ct2/show/NCT05200884 ).

AIM: To compare the clinical and radiographic success rates of an antibiotic mix consisting of metronidazole, minocycline and ciprofloxacin (3Mix-MP) and another mix where minocycline was replaced with clindamycin (3Mix-MP-R) in non-instrumentation endodontic treatment (NIET) of necrotic primary molars and to determine the effect of root resorption on the success of the treatment. MATERIALS AND METHODS: Forty-two necrotic mandibular primary molars from 22 healthy children were randomly assigned to either mixture. Blinded clinical evaluation was conducted after 1, 3, 6 and 12 months by the operator, and blinded radiographic evaluation was conducted at 6 and 12 months follow-ups by other two investigators with inter-examiner reproducibility of 0.95. RESULTS: Overall success rates of 3Mix-MP and 3Mix-MP-R were 80.96% and 76.20% respectively, with no statistically significant difference. Radiographically, resorption of more than one third of the root length had a lower failure rate with no statistically significant difference (p<0.5). CONCLUSION: Primary teeth with necrotic pulp can be treated with 3Mix-MP or 3Mix-MP-R irrespective of the degree of root resorption.
