Abstract
Introduction: Pain of anesthesia injection in children is necessary and one of the most painful local anesthetics is palatal infiltration anesthesia. So, the purpose of this study was to compare the effect of needle gauge on pain and anxiety during palatal infiltration anesthesia injection in children 4-8 years.
Methods: This triple-blind cross-over clinical trial study was performed on 60 children 4-8 years candidates for pulpotomy and SSC treatment of both maxillary first molar teeth. Based on the sequence of using 27- and 30-gauge needles, children were treated during 2 sessions. The anxiety level of children during palatal infiltration local anesthesia was measured using pulse rate (PR) and the pain level of patients was measured using SEM and FPR (objective and subjective criteria).
Results: Anxiety during palatal anesthesia injection with gauge 27 was higher than gauge 30 (treatment effect < 0.001). In subjective and objective criteria, the injection pain in the palatal mucosa with a 27-gauge needle was higher than 30-gauge needle (treatment effect < 0.001). There was no significant difference between earlier and later injection of palatal infiltration with different gauges during treatment sessions (P < 0.05) and according to 0.021 for the period effect, it can be said that the period of receiving two needle gauges had an effect on the average heart rate difference.
Conclusions: The pain of injection in the palatal mucosa with a 27-gauge needle is higher than with a 30-gauge needle, and the use of a 30-gauge needle in the palatal injection of children 4-8 years causes less discomfort than a 27-gauge needle.

Abstract
Introduction: Being overweight is associated with increased cortisol secretion, along with heightened anxiety and depression. This study aimed to compare the effect of six weeks of concurrent moderate-intensity continuous training (MICT) and high-intensity interval training (HIIT) with HIIT training alone on body composition, plasma cortisol levels, and anxiety and depression levels in overweight male students.
Methods: In this semi-experimental research, 27 overweight students were selected and randomly divided into three groups 9: MICT+HIIT concurrent training, HIIT training, and a control group. The MICT )15 minutes of exercise per day at 60-65% of maximum heart rate with an additional 5 minutes every two weeks). The HIIT (3 minutes of running at 70-75% of maximum heart rate, followed by 3 minutes of active rest at 50% of maximum heart rate, with three repetitions in the first two weeks, four repetitions in the second two weeks, and five repetitions in the final two weeks).
Results: Both types of training protocols resulted in reductions in weight, body mass index, cholesterol, low-density lipoprotein, cortisol levels, anxiety, depression, and an increase in high-density lipoprotein (P < 0.05). There was no significant difference between the two types of exercise in terms of effectiveness on these variables; however, only peak oxygen consumption and triglycerides were associated with better changes in the MICT+HIIT group.
Conclusions: For overweight male adolescents aiming for weight loss and improved mental health, HIIT alone is sufficient, and adding MICT does not provide additional clinical benefits.
