RESUMEN
Excessive gingival display is an esthetic issue that is commonly managed by different procedures. Lip repositioning is a modality to address concerns of affected patients. The aim of this review was to investigate the scientific evidence on outcomes and long-term stability of lip repositioning surgery with or without myotomy. The electronic search was conducted in three databases: MEDLINE, Embase, and the Cochrane Library up to October 2019.No publication status, language, or time restrictions were applied. The electronic search was complemented by a manual search of the reference lists.Three hundred thirty-eight studies were screened by title, and 16 articles remained for data extraction. The included studies assessed the lip repositioning procedure in 144 patients aged between 15-59 years (134 females and 10 males). Based on the available data, lip repositioning with myotomy/muscle containment can be a successful treatment for minor discrepancies in gingival display in selected cases. However, further well-organized controlled clinical trials are recommended to derive a conclusion about the long-term stability compared with other alternatives.
RESUMEN
The aim of the present study was to investigate self-perceived need to learn practice management and self reported knowledge in this regard among dentists. A group of five academic staff members of Community Oral Health Department [Tehran Dental School] and four dentists formed an expert panel to develop the content of the course. This group developed a list of topics related to principles of successful dental practice. To investigate the necessity of educating the topics and self-assessed knowledge of the topics, a questionnaire was designed and administered to 55 volunteer dentists. Forty six dentists completed the questionnaire. T-test and Chi-square test were used for statistical analyses. Totally more than two-third of the dentists believed that a huge need exists for education of all the topics The corresponded figure for such topics as ergonomics and medical emergencies was about 90%. About 80% of the dentists felt that they had a vast knowledge of safety and infection control. On the other hand, 54.3% of them reported weak knowledge regarding professional rules and regulations. Self-reported educational need and knowledge of the dentists did not show significant association with their age, gender, and work experience [P>0.05]. The dentists believed in the necessity of educating such topics and evaluated their knowledge as deficient in these areas. This shows the necessity of developing courses on these topics
