Evaluation Of Gingival Crevicular Fluid And Peri-Implant Sulcus Fluid Levels Of Periostin: A Preliminary Report
BackgroundPeriostin is a protein present in alveolar bone and periodontal ligament whose function is related to response to external forces. The aims of this study are to detect levels of periostin in peri-implant sulcular fluid (PISF) and gingival crevicular fluid (GCF) and to evaluate the relationship between periostin, pyridinoline cross-linked carboxyterminal telopeptide of Type I collagen (ICTP), and C-terminal cross-linked telopeptide of Type I collagen (CTX) levels and clinical inflammatory symptoms and duration of functional loading. MethodsThe study population comprised nine women and four men with mean age 43.23 12.48. Twenty bone-level designed dental implants (DIs) placed in molar or premolar sites, without any signs of peri-implant bone loss and with a restoration in function for at least 12 months, were included in the study with 20 contralateral natural teeth (NT) as controls. Clinical parameters and restoration dates of the implants were recorded. PISF, GCF, ICTP, CTX, and periostin levels were evaluated using enzyme-linked immunosorbent assay. ResultsICTP, CTX, and periostin levels were similar between DI and NT groups. There were no statistically significant differences between PISF and GCF values. When implants were grouped as healthy (gingival index [GI]=0) and inflamed (GI0), ICTP levels and PISF volume were lower in healthy implants compared with the inflamed group. Both periostin and CTX levels were negatively correlated with functioning time, suggesting less bone remodeling around DIs at later stages of functioning. ConclusionFindings of this study suggest collagen breakdown products may be used as markers to evaluate peri-implant metabolism.Wo
Nanofilled And Conventional Resin-Modified Glass Ionomer Fillings Combined With Connective Tissue Grafts For Treatment Of Gingival Recessions With Non-Carious Cervical Lesions
The aim of this study was to evaluate the clinical root coverage results of subepithelial connective tissue grafts (SCTG) performed on teeth with gingival recessions and non-carious cervical lesions (NCCLs) that were restored with cervical fillings and compare the results of two different filling materials: resin-modified glass ionomer (RMGIC) and nanoionomer cements (NIC). A total of 54 teeth with Miller Class I gingival recessions with or without NCCLs in 36 patients (28 females, 8 males) were treated with SCTGs. Cervical lesions were randomly treated with RMGIC or MC restorations. Periodontal clinical parameters, height of gingival recession (HGR), width of gingival recession (WGR), height of keratinized tissue, and dentin sensitivity were measured at baseline and 3, 6, and 12 months postoperatively. HGR and WGR values were statistically significantly reduced at all time points when compared to baseline values in all groups. There were no statistically significant differences between the groups in any clinical periodontal parameter (P > 0.05). The percentage of root coverage at 12 months was 89.5%, 90.1%, and 96.2% in the RMGIC, NIC, and control groups, respectively. Successful root coverage with connective tissue grafts may be achieved on teeth restored with RMGIC or NIC cervical fillings.WoSScopu
PRACTICAL IMPLEMENTATION OF EVIDENCE-BASED DENTISTRY INTO DAILY DENTAL PRACTICE THROUGH A SHORT TIME DEPENDENT SEARCHING METHOD
Introduction
Despite the fact that the benefits of implementation of Evidence-Based
Dentistry (EBD) into clinical practice is increasingly being
highlighted, there are still clear limitations in its implementation
into daily dental practice. One potentially important barrier to
effective implementation into practice is the perception of EBD as a
time-consuming process. The aim of the present study is to increase the
familiarity of dental practitioners with the benefits of different
time-dependent `practical' search strategies important to EBD using a
clinical question from the field of dental implantology as an example.
Materials and Methods
The PICO (population, intervention, comparison, outcome) question used
in this study was: ``In young adults with anterior single-tooth implant
what is the effect of immediate or delayed loading on success?{''} A
bibliographic search according to the Haynes 5S pyramid, together with 3
different time-dependent strategies (5 min, 30-min and more than
60-min), were applied.
Results
Both the Haynes 5S Pyramid and time-dependent search strategies revealed
promising results for enhancing decision-making for determining the
feasibility of immediate or conventional loading of anterior single
dental implants. Results clearly showed that selection of the loading
protocol would be case (patient) specific and also indicated high
primary implant stability and bone quality as the most important
prerequisites for a successful immediate/early loading. From among the 3
different time-dependent strategies (5 min, 30 min and more than 60
min), the 60+ min search results were quite comparable with the Haynes
pyramid search results.
Conclusion
It is likely that the different time-dependent search strategies may
have the potential to support the clinical decision making process and
may improve the implementation of EBD into daily dental practice.
Increased time spent searching naturally seems to increase the extent of
this support. However, even with short time-dependent searches, busy
dental clinicians may get an improved idea/opinion regarding a clinical
question
