Comparison of preemptive ibuprofen, acetaminophen, and placebo administration in reducing peri- and postoperative pain in primary tooth extraction: A randomized clinical trial.

BACKGROUND: The management of pain resulting from anesthesia injection, tooth extraction and in the period after extraction is of great importance in pediatric dentistry. OBJECTIVE: The aim of this study was to compare the efficacy of the preemptive administration of ibuprofen or acetaminophen with placebo in reducing the pain during injection, extraction and postoperatively in children undergoing primary tooth extraction. MATERIAL AND METHODS: A randomized, placebo-controlled, triple-blinded clinical trial of cooperative children who needed primary molar extraction by local anesthesia. Sixty-six children aged between 6 and 8 years were randomly assigned to one of three groups: (a) Acetaminophen syrup (320 mg/10 ml); (b) placebo solution; and (c) ibuprofen syrup (200 mg/10 ml). Each of the three solutions was given 30 min before administration of the local anesthetic agent. The Pain level was assessed using the Wong-Baker faces® pain rating scale after injection, extraction, and postoperatively. The Kruskal-Wallis and Mann-Whitney U test were used to evaluate the pain scores between groups at confidence level of 95%. RESULTS: The use of preemptive analgesics showed lower pain scores compared to placebo. Additionally, only ibuprofen significantly reduced pain scores compared to placebo at the points immediately after injection (p = 0.001), immediately after extraction (p = 0.0001) and 5 h after extraction (p = 0.002). CONCLUSION: Preemptive usage of ibuprofen reduces injection pain and relieves both extraction and postoperative pain in children undergoing primary tooth extraction. What this paper or case report adds It adds the knowledge regarding pain relief of injection and extraction in children. Preemptive analgesic medications have a beneficial effect on alleviating postoperative pain following tooth extraction in children. Ibuprofen is an effective analgesic for postoperative pain relief in children undergoing primary tooth extraction. Why this paper or case report is important to pediatric dentists Pediatric dentists may consider preemptive ibuprofen in children before injection and extractions. Identifies that Ibuprofen is an effective method of reducing postoperative pain.

The effectiveness of topical lidocaine in relieving pain related to intranasal midazolam sedation: a randomized, placebo-controlled clinical trial.

OBJECTIVE: Intranasal midazolam (INM) is an increasingly popular agent for sedation in the emergency department and outside the hospital in physician, imaging, and dental offices, to facilitate diagnostic and minor surgical procedures and avoid the need for an operating room and general anesthesia. The use of INM has been commonly associated with a burning sensation of the nasal mucosa. Despite its significance, this subject has received little adequate research focus. The objective of the current study was to evaluate the effectiveness of topical lidocaine in relieving pain related to INM administration. METHOD AND MATERIALS: This was a blinded, randomized placebo-controlled trial. Sixty-three uncooperative children undergoing dental treatment, aged 4 to 11 years, were randomly assigned to one of three groups to receive the drug nasally via a precalibrated spray as per the following assignments: group A received 0.5 mg/kg midazolam, group B received lidocaine 2% prior to 0.5 mg/kg midazolam, and group C received saline 0.9% (placebo), 0.5 mg/kg. Children were asked to record the degree of pain using the Wong-Baker faces scale. Parental acceptance was also rated. RESULTS: Topical lidocaine prior to INM administration reduced the burning sensation in the nasal mucosa and improved the drug acceptance. The median score of pain was 8, 1, and 4 in groups A, B, and C, respectively. The differences among the three groups were statistically significant (P > .05). The children's acceptance and parents' future acceptance regarding the intranasal drug administration was significantly higher in group B. CONCLUSION: INM administration results in burning sensation in the nasal mucosa with high levels of pain. Using topical lidocaine 2% counteracted the burning sensation and achieved a higher acceptance rate and lower pain scores.

A randomized clinical trial to compare pain levels during three types of oral anesthetic injections and the effect of Dentalvibe® on injection pain in children.

BACKGROUND: Pain control is of great importance particularly in pediatric dentistry. The Dentalvibe® is a device that delivers vibration to the injection site in order to reduce intraoral injections' pain. AIMS: The purpose of this study was to compare pain levels caused by three types of anesthesia injections and the effect of the Dentalvibe® on reducing the injection pain. DESIGN: The study included 40 children, and each one received six injections. The injections were divided randomly into two methods: experimental (DV): buccal and palatal infiltration on the maxilla and inferior alveolar nerve block (IANB) with vibration and traditional (TR): receiving the same previous injections without vibration. Moreover, pain was assessed using the FLACC® and Wong-Baker faces® pain scales. Then after, patients were asked about their favorite method. RESULTS: No statistically significant differences were observed regardless of the injection site in subjective and objective evaluation in the (TR) method. Although the pain scores in (DV) method were less than the traditional in most injections, the differences were not statistically significant. CONCLUSIONS: Children experienced similar levels of pain in all sites of injection using the traditional method. The Dentalvibe® did not decrease discomfort and was not accepted more by children.

Exposed human pulp caused by trauma and/or caries in primary dentition: a histological evaluation.

The aim of this study was to compare the pulpal reactions after exposure due to trauma and/or caries and to suggest the appropriate treatment options for the management of pulp, in the light of the histological findings in the primary teeth. Fifteen primary maxillary incisors with pulpal exposure were examined with light microscope in a blind study. After the histological evaluation, teeth were divided into three groups for the etiological factors due to the exposure according to the patient's files: trauma group, caries group and caries and trauma group. The inflammatory infiltration was diminished from the pulp chamber towards the apical third of the root canal in all of the examined teeth. Teeth in the trauma group presented fewer inflammatory cells in the root canal in comparison with other groups. It was concluded that the teeth with traumatic pulp exposure were considered as more likely to respond positively to pulpotomy technique. Pulpectomy or extraction seemed to be indicated for the decayed or decayed and traumatically injured teeth.
