Marginal integrity is one of the important principles of Tooth preparation. To achieve this, a satisfactory gingival displacement procedure is necessary. Aim of this study was to determine an appropriate gingival displacement and to access the gingival displacement on an unprepared tooth using retraction paste and impregnated retraction cord. Fourteen patients were chosen for this in vivo study. Oral prophylaxis was completed 15 days prior to the retraction procedure. Mandibular preliminary impressions were made using rubber base impression material. Gingival retraction procedure was carried out on the right and left 1st mandibular molars alternatively using retraction paste and retraction cord after 2 days of preliminary impression. Retraction paste was placed directly over the sulcus as per manufacturer’s instructions and kept for 2-3 minutes and rinsed and the required length of retraction cord was dispensed and placed into the gingival sulcus using a cord packer and cord was removed after 5 minutes. Post retraction measurements completed made an impression with rubber base impression material by using sectional tray alternatively. Statistical analysis was performed with ANOVA test, paired student t test with SPSS version 21. Patients were more comfortable with retraction paste as against gingival retraction cord with significance observed by observers 1, 3 and 4. (P<0.05). Retraction paste had significantly better retraction ability compared to retraction cord as observed by observer 1, 3 and 4 (p<0.05) whereas no significant difference was observed by observer 2(p>0.05). Retraction paste was significantly less time consuming compared to retraction cord as reported by observer 1 and 4 (P<0.05) and no significant differences between the two systems was reported by observer 3and 4(P>0.05.Within the limitations of the study, both retraction techniques showed adequate gingival retraction for the prosthesis and clinically insignificant differences were seen in both gingival retraction system regarding the retraction achieve. Retraction paste found to be easy for the control of hemorrhage and easy for placement and recommended to use where there is uncontrolled bleeding and sub-gingival finish lines of the tooth preparation However, the amount of vertical gingival retraction observed with the paste retraction system was significantly less than the medicated retraction cord.

“…Practitioners may therefore believe that the placement of crowns on posterior teeth with premolar inclusive remains a more predictable approach than placing large tooth-colored restorations. In addition, caries removal, access cavity preparation during endodontic treatment may also contribute to the fragility of the tooth 26 and hence the need for full coronal coverage.…”

“…Thus, esthetic demands may be seen to be on increase as patients' expectations continue to rise, however further investigation is required. The ultimate goal of single crown replacement is to treat at first crown complication and secondly to improve esthetic and restore function 26 . The very few cases of fixed partial denture seen in this study does not allow for favorable comparison with other similar studies.…”

Aim: The purpose of this investigation was to document the reasons for placement, and replacement of crowns and fixed partial denture in a Nigerian Teaching Hospital. Methods: a retrospective review of patients that had advanced conservative procedures. A data collection form was used to gather the relevant information from the patients' case notes. Section A sought information on age , gender, educational level, patients' occupation etc. Section B recorded information on tooth/teeth involved, reason for fabrication of prosthesis and material used. Results: Three hundred and twenty six had 398 crowns while 23 patients received bridges. Patients' ages ranged from 16-85 years with a mean of 47.7 ± 17.2 years and a male to female ratio of 1:1.3. Thirty five percent of the crowned teeth were in the upper right quadrant, followed by the upper left quadrant with 29.4%. Upper right central incisors were the most frequently (15.6%) crowned teeth. Endodontics and esthetics were the most common reasons for initial crown placement and replacement respectively. About 60% of bridges fabricated were new, while 22.2% of replaced bridges were due to fracture of porcelain and unacceptable marginal adaptation. Conclusion: Endodontics and esthetics were the most common reasons for initial crown placement and replacement

“…It emphasizes the extreme importance of carefully evaluating the strengths and weaknesses of the remaining dentition on an individual basis. 21,22,23,24,25,1 Root Proximities There must be adequate clearance between the roots of proposed abutments to permit the development of physiologic embrasures in completed prosthesis. Malpositioned anterior teeth and the mesiobuccal roots of maxillary molars often present unfavorable root proximities where desired embrasure form is not possible.…”
