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

Study Overview
=================
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Other: Study Group<br> | Other: Hall technique stainless steel crowns<br>* Primary carious tooth will be treated with stainless steel crowns without local anesthesia or caries removal and the increase in the occlusal vertical dimension will be monitored in two subsequent appointments with measuring canine overbite.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Complete canine overbite return | 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. | 30 days |
