Pentax-A 100mm/f4 macro - Dental vs non-dental

Is there any difference between Pentax-A 100mm/f4 macro - Dental vs non-dental version apart from special marking for dental use. Are they optically same?

Thanks
Yusuf

Yes the K, M & A 100/4 macros all had the same optics. five elements in 3 groups. The dental M & A came with a special close-up set.
