This case report describes the immediate dentin sealing (IDS) technique with self-etch dentin bonding agent (DBA) for indirect restorations. To avoid problems related to dentin exposure when preparing teeth for indirect restorations, the sealing of the dentin immediately after preparation and before impression has been recommended. The IDS technique with self-etch DBA prevents the patient from inconveniences associated with dentin demineralization by phosphoric acid in the traditional total-etch technique. The case report presented describes the indirect restoration of the right upper first molar using the IDS technique with a self-etch DBA covered with a low-viscosity composite resin. The lithium disilicate glass ceramic restoration was obtained with a computer-aided design/computer-aided manufacturing (CAD/CAM) system. Selective enamel etching occurred before cementation with resin cement. A follow-up of 15 months revealed success of the treatment and lack of sensitivity. The incorporation of IDS with indirect restoring teeth adhesively may provide better marginal fit, reduce marginal infiltration, protect the dentin-pulp complex, reduce postoperative sensitivity, bring more comfort to the patient, and is long-lasting to the restored teeth. Clinical significance:The IDS technique with a self-etch DBA is an excellent clinical option to avoid some inconveniences of traditional protocols for indirect restorations.
Objective To compare dimensions of natural maxillary anterior teeth and several denture teeth molds and also address differences between genders. Methods A single examiner with a digital caliper measured dental casts of 41 males and 55 females in order to determine CIW (central incisor width), CIL (central incisor length) and WS (width of anterior teeth on a straight line). In addition, WC (width of anterior teeth on a curve) was measured with a flexible ruler. These parameters were also observed on three denture teeth mold charts: Premium Pala, Vivodent and Trilux. The comparison between genders was analyzed using Student’s t-test (?=.05), while absolute frequencies within several ranges were used to compare natural and denture teeth. Results CIW, CIL, WS and WC obtained from males were significantly higher than those found for females (p<0.05). CIW of nearly half of natural and denture teeth were within 8.0–8.5 mm. Almost half of natural teeth presented CIL values within 10.6–11 mm, while the highest frequency of denture teeth was observed within 9.6–10 mm. The majority of natural and denture teeth presented WS values within 42 to 49 mm. Only one denture teeth chart described WC values, which were mainly observed within 44–51 mm, while the majority of WC values obtained from natural teeth ranged from 48 to 55 mm. Conclusion Some commercially available denture teeth present dimensions not observed in natural teeth. Teeth dimensions in function of gender differences must be considered when selecting denture teeth.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
