Background

In this systematic review and meta-analysis, the authors evaluated the pain during scaling and root planing with use of topical anesthetic versus that with the use of injected anesthetic in adult patients.

Types of Studies Reviewed

The authors searched 6 databases for randomized clinical trials in which the investigators compared the clinical effectiveness of intrapocket and injectable anesthetics. The primary outcome was the risk of developing pain or intensity of pain. Quality assessment followed the guidelines from the Cochrane Collaboration’s risk-of-bias tool. The authors performed meta-analyses on studies considered at low and unclear risk of bias.

Results

From 976 articles identified, 6 remained in the qualitative synthesis (4 at low and 2 at unclear risk of bias). Injected anesthetic produced lower pain intensity than did anesthetic gel (P = .03) and required less rescue anesthetic than did topical anesthetic (P < .0001). There was no difference in patient preference (P = .09).

Conclusions and Practical Implications

Injected anesthetic decreased the intensity of pain and the need for rescue anesthetic during scaling and root planing, but the risk of developing pain yielded similar results for injected and topical anesthetics.  相似文献

This systematic review and meta‐analysis analysed whether pain and disruptive behaviour can be decreased by the use of computerized local dental anaesthesia (CDLA) in children. The literature was screened to select randomized clinical trials that compared computerized and conventional anaesthesia. The primary outcome was pain perception during anaesthesia; the secondary, disruptive behaviour. The risk of bias of individual papers and the quality of the evidence were evaluated. After search, 8389 records were found and 20 studies remained for the qualitative and quantitative syntheses. High heterogeneity was detected for both outcomes. For the pain perception, the overall analysis showed a standard mean difference of ?0.78 (?1.31, ?0.25) favouring CDLA; however, when only studies at low risk of bias were analysed (subgroup analysis), there was no difference between the two techniques [?0.12(?0.46, 0.22)]. For disruptive behaviour, no differences were detected for continuous [?0.26 (?0.68, 0.16)] or dichotomous data [0.81 (0.62, 1.06)]. The quality of evidence was judged as low for pain perception and very low for disruptive behaviour. It is concluded that there is no difference in the pain perception and disruptive behaviour in children subjected to computerized or conventional dental local anaesthesia. Notwithstanding, the quality of the available evidence is low.  相似文献

Laryngomalacia is the most frequent congenital abnormality of the larynx, accounting for approximately 60-75% of congenital stridor cases. Despite its benign and self-limited aspects, 10% of cases require intervention. Currently, supraglottoplasty is considered the standard treatment of severe laryngomalacia.ObjectiveTo describe the experience of the authors in the surgical treatment of patients with severe laryngomalacia. Methodology: A retrospective study.MethodThe medical records of 11 consecutive cases of severe laryngomalacia who underwent surgical treatment between 2003 and 2012 were analyzed for age, gender, symptoms, associated diseases, surgical technique employed, extubation time, surgical complications, length of hospital stay and clinical outcome.ResultsOf the 11 cases of severe laryngomalacia, six patients (54.5%) were operated with the use of CO2 laser and five patients (45.5%) were submitted to the cold technique. Only 1 patient (9.1%) required surgical reintervention. There were no cases of surgical complications. All patients had clinical improvement.ConclusionSupraglottoplasty proved to be effective and safe in the treatment of severe laryngomalacia.  相似文献
