ABSTRACT
Background Periodontitis can trigger and perpetuate inflammation in several chronic inflammatory diseases. The association of periodontitis with psoriasis has been investigated earlier, but data are incomplete and the influence of confounders has not been fully evaluated. We examined the relationship of dental and periodontal health parameters in patients with psoriasis and/or psoriatic arthritis. Methods This hospital-based cross-sectional analytical study was conducted in patients with chronic plaque psoriasis, psoriatic arthritis or both, and compared with controls. Dental and periodontal health parameters were assessed based on the WHO oral health assessment method. Multivariate logistic regression was done on variables with significant or near-significant values to find the association between periodontitis and psoriasis and/or psoriatic arthritis after adjusting for confounders. Results Psoriasis and/or psoriatic arthritis were independently and significantly associated with periodontal pockets ≥4 mm in depth. Limitations Causality and temporal relationship cannot be established as this was a cross-sectional study. As in all observational studies, the possibility of unmeasured or unknown confounders exists. Psoriatic arthritis was present only in a small subset of patients. Conclusion Patients with psoriasis and/or psoriatic arthritis have significant periodontal inflammation. This needs to be addressed by dental examination and intervention.
ABSTRACT
Background There is a lack of evidence-based practice regarding the duration of pressure pack placement following tooth extraction. This study aimed to compare the incidence of post-extraction bleeding following 60 minutes versus 10 minutes of pressure pack placement. Methodology A randomized controlled trial was conducted at a tertiary care hospital and included patients requiring intra-alveolar tooth extractions. Patients were randomly allocated into the experimental group or control group by a permuted block randomization method. A blinded observer noted the incidence of post-extraction bleeding. Categorical variables were summarized as frequency and percentage. The chi-square test was used for intergroup statistical analysis. P-values <0.05 were considered statistically significant. Results There were 528 participants, 264 of whom were allocated to each group. The incidence of post-extraction bleeding was 8% and 6.8% in the experimental and control groups, respectively. On bivariate analysis, there was no statistically significant difference between the two groups (p = 0.618; relative risk with 95% confidence interval = 1.0). Conclusions In the majority of cases, hemostasis was achieved in 10 minutes. Therefore, removing the pressure pack after 10 minutes may be advised to ensure hemostasis and, ultimately, save chairside time.
ABSTRACT
Objectives: The aim of present study was to investigate oral manifestations associated with COVID-19 disease. Materials and methods: This cross-sectional study comprised 367 suspects with mild/moderate COVID-19 symptoms who reported to a tertiary care hospital's screening OPD. An in-depth case history was taken, and an oral cavity examination was performed to detect any oral findings. All participants were tested for SARS-CoV-2 using a naso-pharyngeal swab and reverse transcription polymerase chain reaction.Oral manifestations and the results of RT-PCR testing were correlated. Statistical analyses were performed using Epi Info and R software. To estimate the prevalence of oral symptoms, the Pearson chi-square test was used. Results: Oral manifestations were found in 58% of the study population. The difference in the prevalence of oral manifestations between RT-PCR positive COVID-19 patients versus RT-PCR negative suspects was statistically significant (p = 0.007) with xerostomia and dysgeusia being significantly higher in positive patients (p = 0.036 and p = 0.044 respectively) while the prevalence of stomatopyrosis and other intraoral signs was insignificant. Conclusion: Xerostomia and dysgeusia are the common oral manifestations of COVID-19.
ABSTRACT
AIM: The aim of this study was to evaluate the number of intracanal bacteria extruded apically after instrumentation with three different nickel-titanium rotary instruments. MATERIALS AND METHODOLOGY: Forty freshly extracted mandibular premolars were selected, access cavities were prepared, and the teeth were mounted in the bacterial collection apparatus. Root canals were contaminated with a suspension of Enterococcus faecalis and incubated for 24 h at 37°C. The contaminated teeth were divided into four groups of 10 teeth each according to the rotary system used for instrumentation: Group 1: ProTaper universal files, Group 2: MTwo files, Group 3: ProTaper Next files, and Group 4: Control group (no instrumentation). Bacteria extruded after preparations were collected into vials. The number of colony-forming units (CFUs) was determined for each sample. STATISTICAL ANALYSIS: The data obtained were analyzed using the one-way analysis of variance followed by post hoc Tukey's test with a P = 0.05 as the level for statistical significance. RESULTS: The results suggested a statistically significant difference in the number of CFUs between four experimental groups (P < 0.001). CONCLUSION: Least amount of bacterial extrusion was seen in ProTaper Next Group while more bacterial extrusion was seen in MTwo Group.
ABSTRACT
AIM: This in vitro study evaluated and compared the marginal adaptation of three newer root canal sealers to root dentin. MATERIALS AND METHODS: Thirty freshly extracted human single-rooted teeth with completely formed apices were taken. Teeth were decoronated, and root canals were instrumented. The specimens were randomly divided into three groups (n = 10) based upon the sealer used. Group 1 - teeth were obturated with epoxy resin sealer (MM-Seal). Group 2 - teeth were obturated with mineral trioxide aggregate (MTA) based sealer (MTA Fillapex), Group 3 - teeth were obturated with bioceramic sealer (EndoSequence BC sealer). Later samples were vertically sectioned using hard tissue microtome and marginal adaptation of sealers to root dentin was evaluated under coronal and apical halves using scanning electron microscopy (SEM) and marginal gap values were recorded. RESULTS: The data were statistically analyzed by two-way ANOVA and Tukey's multiple post hoc test. The highest marginal gap was seen in Group 2 (apical-16680.00 nm, coronal-10796 nm) and the lowest marginal gap was observed in Group 1 (apical-599.42 nm, coronal-522.72 nm). Coronal halves showed superior adaptation compared to apical halves in all the groups under SEM. CONCLUSION: Within the limitations of this study epoxy resin-based MM-Seal showed good marginal adaptation than other materials tested.
