RESUMO
The aim of this systematic review was to summarize the results of the studies that have compared the physical and mechanical properties of lithium disilicate (LDS) endocrowns constructed for posterior teeth to those retained by post-and-core retention systems. The review was conducted following the PRISMA guidelines. The electronic search process was conducted on PubMed-Medline, Scopus, Embase and ISI Web of Knowledge (WoS) from the earliest available date till 31 January 2023. Additionally, the studies were assessed for their overall quality and risk of bias using the Quality Assessment Tool For In Vitro Studies (the QUIN). The initial search resulted in 291 articles, out of which, only 10 studies met the eligibility criteria. In all studies LDS endocrowns were compared with various kinds of endodontic posts and crowns made from other materials. There were no definite pattern or trends observed in the fracture strengths of tested specimens. There was no predilection observed in failure patters among the experimental specimens. No predilection was observed in the fracture strengths of LDS endocrowns when compared to post-and-core crowns. Furthermore, no differences in failure patterns could be observed when both types of restorations were compared. The authors propose standardized testing of endocrowns against post-and-core crowns in future studies. In conclusion, long-term clinical trials are advocated to compare the survival, failure and complication rates of LDS endocrowns and post-and-core restorations.
RESUMO
BACKGROUND: The management of temporomandibular disorders (TMDs) requires a comprehensive approach that considers multiple factors, including the impact of oral health-related quality of life (OHRQoL). Through this investigation we aim to assess the impact of OHRQoL played in a TMD-afflicted individual. METHODS: Using keywords relevant to our research, such as "Oral health related quality of life," "Oral hygiene," "Temporomandibular joint" and "Temporomandibular disorders," a comprehensive search across multiple online databases was carried out, yielding a total of 632 studies at the preliminary stage of the review. Modified New Castle Ottawa scale was used to assess the quality of studies included. RESULTS: Eight studies were included in the review, out of which six were eligible for further meta-analysis. The studies included in this review employed various OHRQoL measures, including the Oral Health Impact Profile-14 (OHIP-14), the Short-Form 36 Health Survey (SF-36) and the OHIP- 49. All the studies demonstrated significant effect of TMDs on the OHRQoL of the target population under study. CONCLUSION: The impact of OHRQoL on the management of TMD was deemed to be significant. The comprehensive management of TMD should consider the impact of the condition on the individual's daily life and incorporate interventions that address both the physical and psychological aspects of the condition. By improving OqL, individuals with TMD can experience improved overall well-being and quality of life.
