Regenerative endodontic treatment or MTA apical plug in teeth with pulp necrosis and open apices?

By Drs. Ken Hargreaves and Obadah Austah, Dept of Endodontics, University of Texas Health Science Center at San Antonio - Ken Hargreaves, CC BY 3.0 us,

This review of regenerative endodontic treatment (RET) or mineral trioxide aggregate (MTA) apical plug (MAP)in the treatment of teeth with pulp necrosis and open apices used broad inclusion criteria. 144 studies were identified suggesting promising outcomes. However the quality of the available evidence is very low and more high quality research is needed.

Endodontics or extraction and implant for the pulpally involved tooth?


45 studies are included in this review of endodontic treatment or implants for the pulpally involved tooth. The studies are are observational with few comparative studies and while they summarise success rates for various treatments they should be interpreted cautiously. High quality comparative studies are needed as well as agreement on common reporting outcomes.

Autotransplantation of permanent teeth with an open apex


21 methodologically weak studies were included in this review of autotransplantation of permanent teeth with open apex. The findings suggest good survival and success rates however the limited quality of the studies mean the findings should be interpreted with caution.

Mini-screws for orthodontic treatment- self drilling or self-tapping?


Six studies were included in this review comparing the success rates of self-drilling and self-tapping mini-screws in orthodontic practice. The findings suggest no difference but the studies were small and of short duration and none of the included studies was a randomised trial so the findings should be interpreted cautiously.

No robust evidence to indicate maximum insertion torque levels for orthodontic mini-implants


Yesterday (Dental Elf 13th Nov 2012) we looked at a systematic review assessing failure rates of mini-screw implants for orthodontic anchorage.  Today we are looking at a review consider whether recommended maximum insertion torque values of 5 to 10 Ncm were associated with higher success rates of orthodontic mini-implants than those inserted with torque values [read the full story…]
