Staining the Ground Section of the Tooth Using an Innovative Plant Stain Found in the Pravara Region, India.

AIMS: To assess the staining efficacy of the innovative "Pravara" stain on ground sections of human teeth under a stereomicroscope. In this study, the ground sections were stained with the innovative stain. The stain is obtained from a leafless tree called Terminalia chebula. Terminalia chebula, commonly known as Harad, is found in South Asia from India. Few species are found in the Pravara region of Maharashtra, India. MATERIALS AND METHODS: A total of 40 extracted teeth were collected and ground sections of each tooth were prepared. The samples were randomly divided into two groups: group I-control (without stain), group II-study group (the samples in this group were stained with the help of innovative "Pravara" stain). The sections were graded from I to III according to the differentiation and contrast of tissues. RESULTS: The ground sections in group II stained with Pravara stain demonstrated better contrast for structures within sections under a microscope in comparison with group I (control group). CONCLUSION: The study demonstrates the efficacy of a new innovative Pravara stain, which is a simple, economical, quick, and effective staining method for the ground sections of the teeth. CLINICAL SIGNIFICANCE: This innovative Pravara stain is cost-effective, saves time, ecofriendly, and highlights the anatomical structures more effectively and does not fade easily with time.

Hypohidrotic ectodermal dysplasia: A rare entity.

Hypohidrotic ectodermal dysplasia (HED) is a genetic disorder which involves a complex group of inherited conditions. This condition is characterised by the failed development of two or more ectodermal derived anatomic structure; for example, the skin, hair, nails, teeth, and sweat glands. It is a phenotypically heterogenous group of illnesses including anodontia with conical teeth, generalised spacing, reduced ability to sweat, very less hair growth, etc. The pattern of inheritance of HED varies from person to person depending on the type of ectodermal dysplasia (ED). The patterns include X-linked recessive, X-linked dominant, autosomal dominant, autosomal recessive, and spontaneous mutation. There is one such common type of ED more in female than male. It is an X-linked HED (XLHED), characterised by hypohidrosis, sparse hair, and teeth abnormalities. The other type can affect both male and female equally and may be inherited in different ways. The present case is a 21-year-old male who presented with hair, teeth, and sweat gland abnormalities.
