Evaluation of Senior Brazilian Dental Students About Mouth Preparation and Removable Partial Denture Design

Abstract

This study aimed to evaluate the knowledge of senior dental students about mouth preparation and removable partial denture (RPD) design. Two hundred sixty-six senior students from eleven dental schools in the State of São Paulo, Brazil, comprised the sample. The subjects examined two partially edentulous casts mounted on a semiadjustable articulator, answered a questionnaire regarding the treatment plan, and drew the RPD design. The casts consisted of Kennedy Class III, modiication 1 maxillary arch and Class II mandibular arch. Ninety percent of the students believed that mouth preparation should be performed although no one was able to name all necessary procedures. For the maxillary arch, 12 percent of the denture designs were completely appropriate, 51 percent were partially appropriate, and 37 percent were inappropriate. For the mandibular arch, the results were 3 percent, 40 percent, and 57 percent,

Communication Between Dentists and Dental Technicians During the Fabrication of Removable Partial Dentures in Khartoum State, Sudan

“…It is possible that dentists put a greater emphasis on CC-RPD instructions than A-RPD instructions because of the high cost of CC-RPDs, or because CC-RPDs were prescribed by dentists who possessed greater skills than those who prescribed A-RPDs. The results of this research showed that most of the design components for A- and CC-RPDs were not clearly prescribed, which again is similar to previous studies ( 13 , 17 , 23 , 24 ). This again indicates that dentists leave it mainly to technicians to design the prosthesis, which is unacceptable as the dentists should be fully responsible for the RPD design, since they perform the examination, diagnosis, and treatment planning.…”

“…Alternatively, it could be due to weak undergraduate training in writing laboratory instructions and designing RPDs. Less than a quarter of A-RPD and less than half of CC-RPD cases came with written instructions, more than those found by Neto et al ( 23 ).…”

Effect of Interactive Teaching Methods on Removable Partial Denture Designing

“…well planned removable partial denture (RPD) restores oral functions, esthetics and imparts minimum stress to the hard and soft tissues of oral cavity. 1 Poorly designed removable partial dentures may result in periodontal bone loss, caries, gingivitis, periodontal damage and stomatitis of supporting tissues. 2,3,4 Acquisition of skill of partial denture design is crucial to its successful implementation during clinical practice.…”

“…2,3,4 Acquisition of skill of partial denture design is crucial to its successful implementation during clinical practice. 1 Many designs proposed in literature are without sufficient scientific evidence. 5 Worldwide studies have shown disagreements over removable partial denture designs as well as lack of communication skills of dentists, pertaining to details of removable partial denture design to dental laboratories.…”

“…Studies have evaluated undergraduate preclinical and final year students for teeth preparations for better adaptability of partial denture components 14 and RPD designing. 1 The gain of such skill is difficult to assess at preclinical years, when a student is still in a phase of acquiring basic knowledge of prosthodontics. Gradually in third year or final year levels, the interrelations of prosthodontics with other specialties like endodontics/ periodontics and skill of removable partial denture designing and construction are learnt.…”
