Abstract
Abstract
Aims
To conduct a systematic review and meta-analysis of studies that evaluated the width of attached gingiva.
Methods
An electronic search was performed in PubMed, Embase, Web of Science, and CNKI with no language restrictions. Eligible study selection, data extraction, and evaluation of risk of bias were conducted by two authors independently and in duplicate. Any disagreement was solved by discussion or judged by a third reviewer.
Results
Six studies were finally included. Upper incisors and upper canines had pooled Means of 4.48 mm and 3.80 mm, while lower incisors and lower canines had pooled Means of 3.23 mm and 2.40 mm, respectively. Upper premolar and lower premolars had pooled Means of 3.13 mm and 2.16 mm, respectively. Upper molars had a pooled Mean of 3.38 mm, while lower molars had a pooled Mean of 2.40 mm.
Conclusion
The maxillary attached gingiva is always wider than the corresponding mandibular attached gingiva in the same region. In the four quadrants, the attached gingiva from wide to narrow are incisors, canines, molars, and premolars, respectively. Future studies are necessary to evaluate the width of attached gingiva among different gingival phenotypes and age groups.
