The level of maximum occlusal bite force (MOBF) results from the combined action of the jaw elevator muscles modified by jaw biomechanics and reflex mechanisms. The measurement of OBF has been widely used in dentistry to provide useful data for the evaluation of jaw muscle function and activity as well as effectiveness of prosthetic therapy.\n\nMany indicators have been believed to assess the functional status of the masticatory system, such as body size, bite force, number of functional tooth units, and the occlusal contact area. Dental status formed with dental fillings, dentures, position and the number of teeth is an important factor in the value of the OBF.\n\nMany studies were conducted to evaluate the effect of dental caries on OBF. Tsai et al. found a negative correlation between MOBF and the number of decayed teeth. Su et al. reported that the overall tooth decay was not related to the strength of OBF. They suggested that the severity of tooth decay may be more important than the number of teeth exhibiting decay.\n\nStainless Steel Crowns (SSCs) are considered the treatment of choice for severely decayed but restorable primary molars. A recent systematic review by Seale and Randall confirmed their previous work and reviews and appeared to continue to be supportive and in favor of SSCs.\n\nSSCs has been blamed for premature contact related discomfort in the first few weeks after placement of SSCs. Zee and Amerongen reported that premature contacting SSC restored teeth will equilibrate over time and return to pretreatment levels in 15 to 30 days.\n\nSeveral opinions have been reported by parents, children and dentists regarding the improved mastication efficiency after placement of the SSCs. However, the effects of SSCs placement on primary molars on OBF have not yet been investigated'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '6 Years', 'minimumAge': '4 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:- Caucasian\n\n* Healthy child\n* In the primary dentition stage\n* Class I occlusion\n* No facial asymmetry\n* No cross bite\n* Have caries in the eight primary molars indicating placement of SSCs, with no reported pain on biting and no previous restorations\n* No gingival inflammation\n* No para functional habits\n\nExclusion Criteria: did not meet the inclusion criteria stated above\n\n\\-'}, 'identificationModule': {'nctId': 'NCT03254069', 'acronym': 'OBF', 'briefTitle': 'Occlusal Bite Force Changes After Placement of Stainless Steel Crowns in Children', 'organization': {'class': 'OTHER', 'fullName': 'Jordan University of Science and Technology'}, 'officialTitle': 'Changes in Occlusal Bite Force Following Placement of Stainless Steel Crowns on Primary Molars in Children', 'orgStudyIdInfo': {'id': 'Occlusal Bite Force'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Stainless Steel Crown Arm', 'description': 'Children with SSCs placed and followed longitudinal.
