The Effects of Stainless Steel Crowns Applied With Hall Technique on Occlusal Vertical Dimension

Not Applicable

• Conditions: Caries, Dental
• Interventions: Other: Hall technique stainless steel crowns

• Registration Number: NCT03010618
• Lead Sponsor: Bezmialem Vakif University

Brief Summary

In recent years restoring carious of fractured primary teeth with stainless steel crowns (SSC) has became more popular than ever. On the other hand the traditional operative approach of complete removal of caries is steadily losing support due to successful results with materials of high microleakage resistance.

Treatment time and pain control in asymptomatic teeth has always been a problem in children. Hall technique is a minimally invasive treatment protocol that doesn't require local anesthesia, use of rotating devices for caries removal to restore primary teeth with SSC.

But this protocol also raised questions in the scientific community about its possible effects on the dentition and temporomandibular joint (TMJ) for causing primary occlusal contact and increasing vertical dimension.

The aim of our research is to study the effects of Hall technique's premature occlusal contact on TMJ.

Primary Outcome Measures

Name	Time	Method
Complete canine overbite return	30 days	The length of overbite between upper and lower canines will be measured at beginning of the study with marking the overlapping contact point of the upper left canine and length of a straight line to the tip of the lower left canine will be recorded in mm with a standard WHO gingival probe. Full return to this level will be considered as "Complete canine overbite return" and failure to reach this level will in 30 days will require the patient to be scheduled for an extra recall in every 2 weeks until overbite returns to the pretreatment level.
