Orthodontic treatment helps bring teeth in alignment. There is always debate whether tooth should be extracted or not for treating crowding. The present article highlights various advantages and disadvantages of extraction.

This study was conducted with aim to evaluate the efficiency of the newly introduced Opal self-ligating brackets (SLB). The chairside time saved, appliance efficiency, bracket bond failures, breakages and bracket staining in the Opal SLBs were compared with the conventional standard metal manually ligating brackets (MLBs) of MBT system. Seven patients were compared in each group. Standard light curing bonding methods were used in both the group. Chairside time saving, appliance efficiency and bracket bond failures were compared among the groups whereas staining was observed with the SLBs. Appliance efficiency was evaluated by PAR scores. Results showed significant chairside time being saved in SLBs, whereas the appliance efficiency was not significant. Bond failures were found only in SLBs as well as breakages along with staining. Henceforth, we could conclude that though SLBs had advantage of saving chairside time but also had disadvantage of losing more time with bond failures.
