Two moulds were prepared from the master model in order to obtain 12 casts. One cast was scanned for 3D printing digital light processing (DLP) and fused deposition modelling (FDM) 24 impression trays using polylactic acid (PLA). Twelve casts were used to fabricate light cure impression trays. Polyvinyl-siloxane impressions were made on the master model using 36 impression trays and 18 trays each were used to assess dimensional stability and retention strength.Results: In dimensional stability analysis, one sample t-test revealed a statistically significant difference between each group and the master model followed by a one-way ANOVA. There were significant differences, but the difference was less with FDM trays (P < 0.05). In retention strength analysis, one-way Analysis of variance (ANOVA) revealed statistically significant difference between each group and post-hoc test revealed specific difference, the highest with FDM trays (P < 0.05).Conclusion: Dimensional changes were observed at 30 minutes and 72 hours. Lesser dimensional changes were observed when impressions were made using FDM trays followed by DLP and light cure trays. The mean retention strength seen in descending order was FDM, followed by DLP and light cure trays. The best retention strength was noticed when impressions were made using FDM trays.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140915769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forty-five cylindrical composite specimens were prepared to a dimension of 5 mm height and 4 mm diameter. Curing was done using three different exposure modes and duration with dual mode LED curing light as follows: Group I: Ultrafast curing mode for 1 second at 2300 mW/cm2 (n = 15); Group II: Ultrafast curing mode for 3 second at 2300 mW/cm2 (n = 15) and Group III: Standard exposure mode for 20 second at 1000 mW/cm2 (n = 15). Vicker's microhardness measurement was done on both the curing and non-curing sides of the specimen using a motorised diamond-faced micro-indenter (Wilson Wolpwert, Germany) using a load of 50 gram and a dwell time of 30 second.Statistical analysis: Kruskal Wallis ANOVA was used to test for difference between the three groups followed by Mann-Whitney U test for post-hoc analysis.Results: The microhardness values of the composite cured with a conventional curing unit were significantly higher than the ultrafast cured specimens.Conclusion: Low-intensity conventional curing lights were found to perform better than the high-intensity ultrafast curing units.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140915793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The two anomalies on separate teeth are frequently mentioned, but their co-occurrence in a single tooth is a rare entity.Patient concerns: A 20-year-old male patient presented with the rare combination of DE and DI on a dilacerated maxillary right lateral incisor diagnosed using cone beam CT. Treatment: The patient was managed conservatively and is undergoing fixed orthodontic treatment for malocclusion. Despite its uniqueness, very few localized cases have been documented.Takeaway lessons: These anomalies act as an etiological factor for several dental problems for neighboring & opposing tooth.

These sites are coincidently subjected to continuous minor trauma, which led the researchers to opine that IPEH could have a traumatic etiology with a further role of fibroblast growth factors.Clinical presentation: We report a case of IPEH of right buccal mucosa in a 35 years old South Indian male who clinically presented as mucocele. Histopathologically, multiple lesions were found. Immunohistochemical and histochemical findings have also been presented.Discussion: The case is supported by a plausible mechanism involved in the pathogenesis. Thus, IPEH must be included in the clinical differential diagnosis of oral mucoceles and hemangioma.Takeaway lessons: Being a reactive lesion, it does not require extensive treatment.

The interaction between cancer cells and platelets is a well-established phenomenon. Oral submucous fibrosis (OSMF) is a premalignant disorder with a malignant transformation rate of 2-8%. This study aimed to evaluate platelet parameters in OSMF and oral squamous cell carcinoma (OSCC) in the background of OSMF. This cross-sectional study was performed using secondary data retrieved between January 2019 and December 2019 in the Department of Oral Pathology and the Hematology Laboratory.Methods and materials: The data retrieved included 44 histopathologically proven OSCC in a background of OSMF (group III) and 36 OSMF (group II). The haematological parameters of these selected cases were retrieved from the Sysmex XN-1000 automated hematology analyser database. A control group (group I) comprises 50 subjects with normal (negative/unflagged) haematological parameters. All data were statistically analysed using SPSS 20.0. The significance level of tests was set at 5%.Results: The mean platelet volume (MPV) (9.60 [±0.95] P < 0.001), platelet distribution width (PDW) (10.45 [±1.9], P < 0.001), platelet large cell ratio (PLCR) (21.70 [±7.98], P < 0.001), and the ratio of mean platelet volume to total platelet count (MPV/PLT) (0.03 [0.01], P < 0.001) were lower in group III when compared to the other two groups.Conclusions: Platelet parameters may be used as indices in the OSCC in the background of OSMF. However, large-scale prospective studies are necessary to evaluate the utility of these parameters during the malignant transformation of OSMF, thereby encouraging prompt treatment to prevent morbidity and mortality.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140916035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gingival index and plaque index, OHI-s index, and Ainamo and Bay index for bleeding were recorded. Subjects received complete supragingival scaling at baseline and were instructed to use 10 ml of mouthwashes twice a day in their group. Variables were again recorded on the seventh and 14th day after the use of mouthwashes, and data obtained was subjected to statistical analysis. Posthoc and ANOVA tests were used for statistical analysis.Results: It was found that both CHX and herbal mouthwash proved to be more effective than placebo in maintaining gingival health.

The aim of our study was to analyse the cause and pattern of maxillofacial injuries & to correlate the aetiology and pattern of facial injury.Materials and methods: This prospective study includes 304 patients with facial trauma, who reported to our institute within a time span of 2 years. Data were collected on basis of sociodemographic status plus additional data obtained on type of injury, aetiology, location and status of the victim.Result: The most frequent cause of maxillofacial trauma (MFT) was fall (43.3%) followed by RTA (34.2%) and assault (15.1%). In upper 3rd face region frontal bone fracture was prevalent with 1.3%, while in the midface, zygomatic complex (ZMC) fracture (3.9%) and in lower 3rd part of face, mandible fracture (42.8%) and dentoalveolar fracture (30.2%). Mandible was the most prevalent site for trauma. Although fall was the main aetiological factor in our study, midfacial injuries were mainly due to assault and RTA. Combination of mandibular fracture and soft tissue injury were mainly seen in RTA and injury due to fall. Conservative management was mainly employed for treatment with 46.1% followed by ORIF with 36.2%.Conclusion: Changing trend in aetiology of MFT was noted. Furthermore, study should be conducted for better understanding, and to carry out preventive measure for the same.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140916389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
