Autoimmune disorders are formed in the body as an outcome of inappropriate immune response against its own tissues. Failure of this immune system to recognize the body's normal constituents as "self" will result in inflammation and tissue damage. Several immune based mechanisms form the basis of autoimmune disorders in the body. Management of these lesions is based on the diagnostic criteria, evaluation of clinical and oral manifestation, and laboratory investigations of these lesions. There is currently no definitive cure for all autoimmune disorders, although in rare cases they may disappear on their own. As patients experience temporary remissions in symptoms or progressive worsening, our pharmacological management are targeted only for symptomatic relief and arrest the progression of the lesion. A detailed approach to titles and abstracts of importance in this field on the topic of interest via review and case reports was included. This review article highlights on various immune pathogenic mechanisms and treatment modalities of autoimmune disorders.
Objective:This in vitro study was designed to assess shear bond strength (SBS) of ormocer flowable (OF) resin as a luting agent, ormocer as an indirect veneer material with portrayal of modes of failures using scanning electron microscope (SEM).Materials and Methods:Sixty maxillary central incisors were divided into Group I, II, and III with 20 samples each based on luting cement used. They were OF, self-adhesive (SA) cement, and total etch (TE) cement. These groups were subdivided into “a” and “b” of ten each based on the type of veneering materials used. Veneer discs were fabricated using Ormocer restorative (O) and pressable ceramic (C). Specimens were thermocycled and loaded under universal testing machine for SBS. The statistical analysis was done using one-way ANOVA post hoc Tukey honest significant difference method.Results:A significant difference was observed between the Groups I and II (P < 0.05). The highest mean bond strength when using ormocer veneer was obtained with the Group Ia (19.11 ± 1.92 Mpa) and lowest by Group IIa (8.1 ± 1.04 Mpa), whereas the highest mean bond strength while using ceramic veneer was of similar range for Group Ib (18.04 ± 4.08 Mpa) and Group IIIb (18.07 ± 1.40 Mpa). SEM analysis revealed OF and TE presented mixed type of failure when compared with SA where failure mode was totally adhesive.Conclusion:OF was found equally efficient like TE. Bond strength of ormocer as a veneer was not inferior to ceramic making it one of the promising additions in the field of dentistry.
Cerebriform tongue (CT) is diagnosed to be a benign clinical condition that is characterized by grooves on the dorsal surface of the tongue and referred with other terminologies such as the scrotal tongue, grooved tongue, lingua fissurata, and lingua plicata which can be chronic trauma, vitamin deficiencies, and probably not a developmental malformation. The incidence of this condition was predominant among males and found to be higher with increasing age. It is very rarely observed in children. It is usually painless and sometimes food debris accumulation can irritate. CT has been reported with the association of various systemic factors and syndromes. A case of a 62-year-old male with CT is presented along with the review of the literature.
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.
