While African Health Sciences has been freely accessible online there have been questions on whether it is Open Access or not. We wish to clearly state that indeed African Health Sciences is Open Access. There are key issues regarding Open Access needing clarification for avoidance of doubt:
- 1. Henceforth, papers in African Health Sciences will be published under the CC BY (Creative Commons Attribution License) 4.0 International. See details on https://creativecomons.org/)
- 2. The copyright owners or the authors grant the 3rd party (perpetually and in advance) the right to disseminate, reproduce, or use the research papers in part or in full, format/medium as long as:
- No substantive errors are introduced in the process
- Attribution of authorship and correct citation details are given
- The referencing details are not changed.
Should the papers be reproduced in part, this must be clearly stated.
- 3. The papers will be freely and universally accessible online in an easily readable format such as XML in at least one widely recognized open access repository such as PUBMED CENTRAL.

Facial approximation: Evaluation of dental and facial proportions with height
Abstract
Objective: To explore if any relationship exists between dental and facial proportions as well as the height of the individuals.
Methods: Two hundred and four dental students of the Obafemi Awolowo University volunteered to participated in the study. The lower facial height, inter incisal, inter canine, and intercommisure distances, as well as the height of the participants were measured. The data were imputed, analyzed, and reported as simple frequency, means and standard deviations using the SPSS vs 11. Statistical significance was inferred at p<0.05.
Result: The mean values of all the parameters measured were significantly higher in males than females. None of the mean values measured were coincident. However, a significant correlation exists between intercanine and interincisal distances(r=0.8) while a weak but significant negative correlation exists between the intercanine distance and the difference of the intercommisural and intercanine distances (r=-0.4).
Conclusion: The study showed no relationship between intercanine distance, interincisal distance, lower facial height, and the height of the participants with the intercommissural distance. Hence, intercommissural distance may not be used in marking canine line during bite registration procedure. At best, 1.75-2.45 cm should be subtracted from the intercommissural distance to determine the intercanine distance.
