ABSTRACT
Background: Direct pulp treatment is carried out when a healthy pulp gets mechanically/accidentally exposed during the operative procedures or trauma. Aim: To determine the effects of various direct pulp capping materials as measured by the clinical and radiographic analysis. Design: Two reviewers performed a database search of the studies published between January 2005 and November 2020. The inclusion criteria were papers published in the English language; children aged 3–12 years having deep carious lesions in primary teeth. All potential studies were acknowledged by their title and abstract. The full-text analysis of potentially relevant studies, the selected studies were included in the systematic review. A meta-analysis calculation was performed for the overall data and the subgroup data. Results: The database searching led to 57 articles, which were of direct pulp treatment in primary teeth, after the removal of duplicates, 55 records remained but did not meet all inclusion criteria. A high variability was observed among the papers. Further filtering with criteria led to nine articles, which met all inclusion criteria. Meta-analysis demonstrated the success rates of DPT in primary teeth (95% confidence interval −0.799–0.898); P < 0.001. Clinical assessments of various direct pulp capping materials suggested 84.9% of success irrespective of the material used. The nine studies were heterogeneous according to the random effect model (P < 0.001, I2 = 84.08%). Conclusions: Direct pulp treatment has the advantage of being a conservative vital pulp therapy reducing the need for a more invasive treatment.
ABSTRACT
Objective: The intent of this study was to evaluate the effect of plastination on the morphology and structure of stored organs, to find out how much accuracy a plastinated specimen has, and to look into the changes that occurred because of plastination. Materials and Methods: A human fetus of gestational age 24 weeks was plastinated, and 3D CT scan evaluation of the fetus was done. Results: The results showed normal, well-defined, clearly identifiable organs, with no alteration in morphology and structure of organs. Conclusion: In our opinion, plastinated specimens are better way of visualization of morphology and structure of stored organs, which is a useful tool for teaching as well as for research purposes.

Incisive fissure is a well known anatomical structure in human palate. The term incisive fissure, given by Wood et al, was previously regarded as incisive suture. Incisive fissure on a radiograph is seen as bilateral radiolucent line on the palate during early fetal life. It disappears with age and generally cannot be seen on the palatal and nasal aspect of the adult skull. Plastination is a technic of preparing a dry, colored, nontoxic, durable, odorless, natural looking specimen. A human fetus of gestational age 24 weeks was plastinated, radiographs and 3D CT (VRT) Scan of the fetus was taken. The obtained images were studied and results were drawn.
