Dr. Bharat Joshi
I’m a periodontist and academician with a strong clinical and teaching background. Over the last 4 years and 8 months, I’ve been actively involved in dental education, guiding students at multiple levels including dental hygienist, BDS, and MDS programs. Currently, I serve as a Reader at MMCDSR in Ambala, Haryana—a role that allows me to merge my academic passion with hands-on experience. Clinically, I’ve been practicing dentistry for the past 12 years. From routine procedures like scaling and root planing to more advanced cases involving grafts, biopsies, and implant surgeries. Honestly, I still find joy in doing a simple RCT when it’s needed. It’s not just about the procedure but making sure the patient feels comfortable and safe. Academically, I have 26 research publications to my credit. I’m on the editorial boards of the Archives of Dental Research and Journal of Dental Research and Oral Health, and I’ve spent a lot of time reviewing manuscripts—from case reports to meta-analyses and even book reviews. I was honored to receive the “Best Editor” award by Innovative Publications, and Athena Publications recognized me as an “excellent reviewer,” which honestly came as a bit of a surprise! In 2025, I had the opportunity to present a guest lecture in Italy on traumatic oral lesions. Sharing my work and learning from peers globally has been incredibly fulfilling. Outside academics and clinics, I’ve also worked in the pharmaceutical sector as a Drug Safety Associate for about 3 years, focusing on pharmacovigilance. That role really sharpened my attention to detail and deepened my understanding of drug interactions and adverse effects. My goal is to keep learning, and give every patient and student my absolute best.

At around 13 weeks of pregnancy, certain measurements during the nuchal translucency (NT) scan are important for assessing the risk of chromosomal abnormalities. The CRL (crown-rump length) of 73.5mm and FHR (fetal heart rate) of 166 bpm are generally in the range you’d expect at this gestational age. The NT measurement of 2.4mm is also within typical limits but it’s closer to the upper end of normal. Generally, anything under 3.0mm is considered to be within the normal range, but keep in mind that NT measurements need to be considered in conjunction with the mother’s age, blood tests, and other factors to accurately assess risk. The nasal bone (Nb) measurement of 3.5mm is another parameter that’s typically checked, and its presence and measurement here typically supports normal development, assuming everything else correlates well. However, these findings should ideally be reviewed alongside an integrated screening that includes biochemical markers from blood tests for a more comprehensive risk assessment. It’s typically a good idea to discuss these results with your obstetrician or a maternal-fetal medicine specialist who can give you an interpretation tailored to your individual risk factors. They can help you understand if any further follow-up or testing, such as non-invasive prenatal testing (NIPT) or diagnostic tests like CVS or amniocentesis, might be warranted. While your measurements seem mostly reassuring based on generalized data, definitely consult your healthcare provider for personalized advice suited to your unique pregnancy and health history.
