Extraction of permanent maxillary teeth without palatal injection: a meta-analysis.

ABSTRACT

OBJECTIVE: The objective of this meta-analysis was to assess the operation success rates of extracting maxillary teeth without palatal injection. STUDY DESIGN: PubMed, Cochrane Library, EMBASE, SinoMed, and the references of the identified full-text articles were searched for relevant studies, published until June 2017, that met the eligibility criteria. Experimental data were combined by meta-analysis by using RevMan 5.3 software. RESULTS: Seven randomized controlled trials were included in this meta-analysis. Compared with the control groups (given the recommended combination of buccal and palatal anesthesia, also known as routine infiltration anesthesia), experimental group (single buccal anesthesia) for the removal of maxillary permanent teeth at conventional doses, which resulted in a reduction in the success rate (odds ratio = 0.14; 95% confidence interval 0.07-0.27; P < .00001). CONCLUSIONS: The results revealed that without the use of palatal injections, the success rate of maxillary permanent teeth removal is undoubtedly reduced. However, larger and higher-quality tests are needed to confirm and optimize the effect of this anesthesia procedure.
