Cup Of Coffee With Dr Himani Hasaji

1. How did your journey in the dental profession begin, and what were the milestones that shaped it?

From the very beginning, I knew I didn’t just want to be a dentist — I wanted to be a holistic dentist. For me, that meant stepping into every kind of setup possible. I’ve worked in super glam, high-end clinics where patient detailing and experience matter the most, in fast-paced corporate chains where efficiency and systems rule, and in CGHS/government setups where limited resources challenge your creativity and compassion.

Each of these experiences shaped me in unique ways — teaching me empathy, precision, and adaptability — lessons I carry into my practice every single day.

2. What inspires you to stay passionate and committed to dentistry, even during challenging times?

People inspire me. Over the years, I’ve noticed a beautiful shift — patients today are genuinely curious about their smiles. They ask questions, they care about their oral health, and they’re invested in improving it. Seeing how a small change — sometimes as simple as aligning a tooth or improving a shade — can completely transform someone’s confidence is what keeps me going. And of course, dentistry allows me to be my own boss — a privilege that pushes me to stay committed and creative, even during tough days.

3. Who is your role model in dentistry, and how have they influenced your professional journey?

My biggest inspiration is Dr. Shruti from MAIDS. She’s done both her BDS and MDS there, and what amazes me most is her discipline. Even today — while managing family life and raising two kids — she studies for a few hours every single day. That level of dedication reminds me that dentistry isn’t a career you complete; it’s a lifelong learning journey.
I aspire to bring that same philosophy to my practice — to always stay updated so my patients receive care that’s rooted in both compassion and the latest science.

4. How do you balance academics, work, and personal interests?

For me, balance isn’t optional — it’s essential. Dentistry can be intense, so I make sure to pause and recharge when needed. I’ve even taken two-month breaks between jobs just to travel, rest, and reset before starting fresh. Some people might think that’s unconventional, but that balance fuels my best work.
When you’re happy and fulfilled outside the clinic, you naturally become a more patient, empathetic, and focused dentist inside it.

5. What advice would you give to dental students and young professionals?

The early stages can be tough — there’s little earning, lots of expenses, and often a sense of uncertainty. But don’t let that phase define you. Use that time to learn, document, and grow.
Keep updating your skills and build expertise in areas your peers might overlook. When you do that, you create your own niche — and patients will value that uniqueness.
Remember, confidence comes from competence. Keep learning, and everything else will follow.

💎 A Smile That Reflects a Life Well-Lived

Dr Himani Hasaji’s story is more than a professional journey — it’s a lesson in purpose, balance, and evolution. She’s not just crafting smiles; she’s crafting a philosophy that blends science, art, and humanity.

Cup Of Coffee With Dr Janhavi Bangar

From wax carvings to real-life artistry — Dr Janhavi Bangar’s journey through dentistry is a story of growth, grit, and genuine passion. In this candid interview, she opens up about the milestones that shaped her, the mentors who molded her mindset, and the balance between precision and play in her life as a young dentist.

Beginnings: Finding Meaning in Every Milestone

1️⃣ Can you share how your path in the dental profession began and the key milestones that shaped it?

Honestly, my path started a bit like a wax carving — rough at the edges but shaping into something meaningful. One of my earliest “wow” moments was assisting in an implant surgery. I remember thinking, “We literally put screws into bone and call it art — this is wild and fascinating!” Another turning point was getting 73% in my first year. It wasn’t just a grade; it was proof that I could actually be good at this. Then came the decision to pursue masters and later my internship at GDC Mumbai as an extern — that’s where it clicked: Yes, MDS is my road. Each of these milestones felt like building blocks, shaping not just my career, but also my confidence in it.

Passion That Persists: Finding Joy in Every Smile

2️⃣ What inspires you to stay passionate and committed to dentistry, even during challenging times?

For me, it’s simple — dentistry gives me the rare privilege of seeing the impact of my work almost instantly. A patient walks in hiding their smile, and after treatment, they walk out grinning ear to ear. That transformation, that joy — it’s addictive. It reminds me every day why I chose this. Sure, there are tough times — long hours, endless reading, sometimes frustrating cases — but then I remember what Dr. G.V. Black, the father of modern dentistry, once said: “The professional man has no right to be other than a continuous student.” So even when I’m tired, the idea that I’m constantly learning while helping someone regain their smile keeps me moving.

Mentorship and Inspiration: The People Behind the Progress

3️⃣ Who is your role model in the dental field and how has this person influenced your approach to patient care, academics, or professional growth?

It’s impossible to pick just one — every mentor I’ve had has shaped me in some way, like different teeth in the same arch, each serving its unique function.

  • Dr. Swati Pustake has been my guiding light. Her calmness in difficult situations taught me lessons that no textbook ever could.
  • Dr. Bikash Pattnaik inspires me daily with his combination of brilliance and humility — he’s living proof that academics, health, and fun can coexist beautifully.
  • Dr. Komal Majumdar and Dr. Moez are orators who can hold a room’s attention like no one else — they’ve shown me that communication is just as vital as clinical skill.

Together, they’ve shaped my philosophy: dentistry isn’t just about perfecting your hand skills — it’s about shaping your mindset, resilience, and ability to connect with people.

Balance Beyond the Clinic: Living Life Fully

4️⃣ Could you discuss the strategies you use to manage academic responsibilities alongside your personal interests or hobbies?

My strategy is simple: dentistry is a part of my life, not my entire life. On most days, I’m the dedicated student, clinician, and resident — working 12–13 hours if needed. But I’ve also promised myself that I won’t lose out on living. That one free day or Sunday, I make sure I really live — whether it’s brunch with friends, a trek, volleyball, painting, creating content, or even participating in college fests and fashion shows. After all, what’s the point of being a prosthodontist if you don’t know how to fix the “missing tooth” of fun in your own life? As the saying goes, “Don’t get so busy making a living that you forget to make a life.”

Words of Wisdom: Lessons for Aspiring Dentists

5️⃣ What advice would you give to current dental students and aspiring dentists?

My biggest advice is have clear intent, stronger than your luting cement. Dentistry is demanding, yes, but if your values are strong ,whether it’s honesty in studies, compassion in patient care, or integrity in friendships , you’ll stand strong no matter what. Patients can always sense genuine energy; if you’re invested in them, half the treatment is already successful.

And don’t forget to have fun along the way , pursue the things you’re passionate about outside dentistry too, because that joy will reflect in the kind of dentist you become. Like Dr. William Osler said: “The good physician treats the disease; the great physician treats the patient who has the disease.” I’d like to believe the same applies to us: “The good dentist restores the tooth; the great dentist restores the smile — and the person behind it.”

Cup of Coffee with Dr Karthik D’nojaa

🎙️ From Scalpel to Spotlight: A Candid Chat with Dr. Karthik

MDS Periodontology | Educator | Host of the India’s Most Famous Dentist Podcast | Winner of the Golden Mic Award for Best Dental Podcast

If you’ve scrolled through dental Instagram lately or tuned into any student-friendly podcast, chances are you’ve come across Dr. Karthik. Known for his calm voice, creative visuals, and deep conversations on the India’s Most Famous Dentist Podcast, he’s someone who makes dentistry feel a little less intimidating—and a lot more inspiring.

We caught up with him to talk about his journey, his motivation, and his advice for the next generation of dentists.


🦷 Q1. So, Dr. Karthik—where did it all begin? What pulled you into dentistry?

I think I was always inclined toward the artistic side of things. Even before dentistry, I’ve had this natural urge to focus on precision and the smaller details – whether it was sketching, filmmaking, or editing. I’ve always believed that creativity and precision go hand in hand. Those who’ve seen my videos or podcast visuals probably notice that – my team and I put a lot of thought into how things look and feel, because I think dentistry is also an art form.

So for me, it wasn’t a trickle-down choice or a backup plan. Dentistry – and especially periodontics matched that part of me that loves design, structure, and creating something that lasts. It gave me a space where art, science, and communication meet – and that’s what continues to drive me every day.

I think I’ve always had this curiosity to understand how things work – especially the human body. During my early years, I could spend hours with anatomy, physiology, pharmacology, or medicine textbooks. They completely fed that curiosity of knowing how the body is designed and how it functions.

But soon, I realized that knowing wasn’t enough – I had this restless urge to do something with that knowledge. I’m a very hands-on, high-energy person, so I naturally gravitated toward dentistry. The pre-clinical labs – wax patterns, tooth carvings, crown preparations – all of that gave me a creative outlet.

Then came the clinical years – Conservative Dentistry, Prosthodontics, Periodontics, Oral Surgery, Orthodontics, Oral Medicine and Radiology, Pedodontics and Public health Dentistry – and that’s when I really found my rhythm. Periodontics especially connected deeply with me because it’s where precision meets biology. You can see what you’re working on, and every millimetre matters – it matched my personality perfectly.

Over time, those experiences shaped how I approach not just treatment, but also communication whether it’s through my podcast, my content, or my work with students and clinicians. Each phase was a milestone that built both the clinician and the creator in me.


💪 Q2. What keeps you going when the days get tough?

I always start with history. When you stay connected to your roots, it gives you a deep sense of value for what you have today.

If you look back, the pioneers of dentistry – the scientists, clinicians, researchers – they built this field with almost no resources. They worked for patient welfare, comfort, accessibility, and affordability, long before we had the kind of technology and conveniences we rely on now.

That perspective really keeps me grounded. Whenever I go through a challenging phase, I remind myself – we are walking on a path that so many before us have built through pure dedication and passion. All we need to do is keep that spirit alive.

In fact, this is something I often tell students: value what you have today, because it’s the result of decades of evolution. On my podcast, we’ve done a few episodes on the History of Dentistry -featuring experts and curators from dental museums, and even conversations on how dentistry was practiced in the 1950s compared to now. Those episodes truly help you appreciate how far we’ve come as a profession.

So, whenever I feel tired or demotivated, revisiting that history – the legacy of our field – reignites my purpose. It reminds me that being part of dentistry itself is a privilege.


🌟 Q3. Do you have a role model—or many?

Well, for me, it’s hard to name just one person as a role model. I’ve been fortunate to meet and learn from so many incredible dentists throughout my journey.

During my undergraduate days, I was very active in both curricular and extracurricular activities -which gave me the chance to interact with dentists who were doing outstanding work, nationally and internationally. Then in post-graduation, I think I must have attended over fifty national and international dental education programs. Each of those experiences connected me with mentors, clinicians, and researchers who were masters in their domains.

So for me, keeping just one role model has always been difficult. I try to stay alert and absorb something valuable from everyone I meet – because sometimes a small line of advice from an experienced dentist can be worth more than what you find in textbooks.

And on top of that, my podcast journey has been a huge source of learning. Every guest I’ve hosted – whether it’s Dr. Anuj Agarwal, Dr. Ashish Jain, Dr. Suresh Ludhwani, Dr. Moez Kahkiani, or someone like Dr. Sandesh Mayekar who’s contributed in all aspects – each of them has left a strong impression on me. I’ve learned a lot from their experiences, their perspectives, and even their attitude toward growth.

So, rather than one role model, I’d say I have many – and collectively, they keep me grounded, curious, and inspired to do better every day.


🎬 Q4. How do you juggle academics, practice, and content creation?

Yes, it has been challenging – but not because of lack of time or multitasking. The real challenge often comes from the mindset around us. Many people assume that if you’re doing something beyond your main work – like pursuing hobbies, content creation, or any parallel interest – you’re somehow not focused on your core field.

But that’s not true at all. That’s just a shallow perception. I genuinely believe that your hobbies and creative skills can strengthen your main profession, if you channel them in the right way. For me, filmmaking, editing, communication – all of these have actually helped me explain dentistry better and connect with people more effectively.

I once asked a very well-known businessman of our country – whose discussion will soon be out on my page – about how he managed to stay focused amid so much noise. He gave a brilliant analogy. He said, ‘In your generation, you have noise-cancellation headphones. I naturally developed the ability to switch my ears on and off – to only listen to what truly matters.’ That line really stayed with me.

And honestly, that’s the key. You have to learn to tune out the outer noise. Focus only on what adds value. Everyone has immense creativity, energy, and potential – it’s just the distractions that pull you back. If I have to put it as a strategy – I’d say: eat, sleep, do one thing for yourself, one for your family, and one for society – and repeat.


🪥 Q5. What’s your advice for dental students and young clinicians?

My advice would be simple – don’t just study dentistry, live it. Dentistry today isn’t only about clinical skills; it’s about how you think, how you communicate, and how you keep learning every single day. Be curious – not just about treatments, but about people. Understand your patients, listen to them, and value the privilege of being trusted with their health.

Secondly, don’t compare your journey with others. Everyone’s timeline is different. Some people bloom early, some take time – and both are absolutely fine. What matters is that you stay consistent and keep improving your craft.

Also, take your creative side seriously. Whether it’s content creation, design, research, or patient communication – your ideas and hobbies can actually strengthen the field if you channel them with purpose.

And lastly, always remember – this profession was built on service and sincerity. So stay grounded, stay ethical, and contribute back in your own way.

If I had to sum it up in one line,
I’d say: Keep learning, stay curious, do good work – and life will give you more than you ever expected.

And yes, I’d genuinely encourage students and young dentists to watch my show – the guests we’ve had share incredible insights that can really shape how you look at the profession. And feel free to connect with me if you ever want to discuss ideas, to learn, or just want to talk – I’m always happy to interact with passionate minds. Thank you.

Molar Distalization: Buccal Appliances VS Palatal Appliances

Molar distalization is a crucial technique in orthodontics, particularly for patients with Class II malocclusion. Thanks to advancements in biomechanics, materials, and technology, orthodontists now have access to a variety of intramaxillary intraoral appliances that can apply light, continuous forces for effective molar distalization. These appliances have become a game-changer, providing us with more precise control and predictable results.

Types of Intramaxillary Appliances

The application of forces in molar distalization can come from two primary areas: the buccal or the palatal region. Depending on where the force is applied, appliances can be categorized into two broad groups:

  1. Buccal Force Application: These appliances apply force from the outside of the dental arch.
  2. Palatal Force Application: These appliances exert force from the roof of the mouth.

Additionally, the force mechanisms can be divided into two categories:

  • Friction-Free Mechanism: This type involves appliances like the pendulum, which are designed to move the molars without causing significant friction.
  • Sliding Mechanism: Appliances like nickel-titanium (NiTi) coil springs use a sliding mechanism to apply force, creating a more dynamic force delivery system.

Each of these appliance types has its own set of advantages and drawbacks, and comparing their efficiency in achieving molar distalization is key to making evidence-based treatment decisions. However, due to the limited number of randomized clinical trials, a meta-analysis is often not possible. That said, a comprehensive analysis of existing studies can still offer valuable insights into how these appliances work.

Treatment Outcomes: Overall Effects

When all intramaxillary appliances were considered together, some general findings emerged:

  • First Molar Movement: On average, first molars moved 2.9 mm distally, but this came with a 5.4° of distal tipping.
  • Incisor Movement: The incisors shifted mesially by 1.8 mm with 3.6° of mesial tipping.
  • Premolar Movement: Premolars showed a mesial shift of 1.7 mm, though tipping was less pronounced.

Vertical movements were generally extrusive for incisors and premolars, with incisors showing an average extrusion of 0.4 mm and premolars 1.1 mm. Interestingly, molar vertical movements were not statistically significant, indicating that the main effect on molars was distal movement and tipping rather than vertical displacement.

Treatment Effects: Buccal vs. Palatal Appliances

Now, let’s delve into the specific effects of buccal and palatal appliances. These results highlight the different ways these appliances move teeth:

  • Buccal Appliances:
    • Molar Movement: Molar distal movement was 2.6 mm, with a more significant tipping of 8.3°.
    • Incisor Movement: Incisors moved mesially by 1.9 mm with 5.0° of mesial tipping.
    • Premolar Movement: Premolars demonstrated a 2.0 mm mesial shift, accompanied by 7.0° of mesial tipping.
    • Vertical Movement: Premolars showed a slight extrusion of 0.7 mm, while incisors had a more modest extrusion of 0.2 mm.
  • Palatal Appliances:
    • Molar Movement: Molar distalization was slightly more pronounced, with 3.1 mm of movement and 3.6° of tipping.
    • Incisor Movement: Incisors exhibited a mesial shift of 1.8 mm with 2.9° of mesial tipping.
    • Premolar Movement: Premolars moved mesially by 1.3 mm with less tipping than buccal appliances.
    • Vertical Movement: The extrusion for incisors was 0.7 mm, and premolars showed an extrusion of 1.0 mm.

Molar Distalization and Anchorage Loss

The primary effect of noncompliance intramaxillary appliances is molar distalization, which is typically achieved through a combination of crown distal movement and tipping. While distalization is the goal, a common side effect observed is loss of anchorage. This loss can be seen in the mesial movements and extrusions of incisors and premolars.

Key Findings:

  • Molars: Show a combination of distal crown movement and distal tipping.
  • Incisors: Exhibit mesial movement, tipping, and extrusion.
  • Premolars: Display mesial crown movement and extrusion.

As with any treatment modality, careful planning is required to manage these unintended side effects and achieve the best possible clinical outcomes.

Buccal vs. Palatal Appliances: Tipping and Force Mechanics

One interesting observation in the study was the difference in tipping effects between buccal and palatal acting appliances. Palatal appliances consistently resulted in less tipping of teeth compared to buccal appliances, as indicated by the non-overlapping confidence intervals.

Why the Difference?

The key reason for this difference lies in the moment arm of the force. In palatal appliances, the line of action of the force is closer to the center of resistance of the tooth, leading to less tipping and more controlled molar movement.

Table 1: Comparison of Tipping between Buccal and Palatal Appliances

Appliance TypeMolars Distal Movement (mm)Molars Tipping (°)Incisor Mesial Movement (mm)Incisor Tipping (°)Premolar Mesial Movement (mm)Premolar Tipping (°)
Buccal Appliances2.68.31.95.02.07.0
Palatal Appliances3.13.61.82.91.33.0

This table highlights the greater tipping observed with buccal appliances compared to palatal appliances, as well as the differences in molar distalization and mesial movement of incisors and premolars.

The Nance Button: Anchorage Considerations

Another point of discussion is the use of the Nance button to reinforce anterior anchorage during molar distalization. While it can support anchorage to some extent, it does not provide absolute anchorage. This is because the Nance button, as part of the anchorage unit, cannot completely resist mesial forces during molar distalization. Clinically, this often results in an increased overjet and proclination of maxillary incisors.

Clinical Tip:

For patients already presenting with an increased overjet, orthodontists must proceed with caution when prescribing these appliances. These cases may require additional measures to control the overjet and manage incisor proclination.

The Pendulum Appliance: A Look at Tipping and Movement

The pendulum appliance, a popular friction-free appliance, was noted in the study to cause the greatest distal tipping of molars. However, this tipping was correlated with a larger amount of distal crown movement. Interestingly, this tipping can often be corrected with the use of molar uprighting bends.

Table 2: Molar Distalization and Tipping with the Pendulum Appliance

Movement TypeMolar Distal Movement (mm)Molar Tipping (°)
Pendulum Appliance3.49.0

This table shows that the pendulum appliance can achieve significant molar distalization but at the cost of increased tipping. These tipping movements can be addressed with molar uprighting bends, which can help reduce the tipping angle.

Factors Affecting Molar Distalization

Several factors can influence the effectiveness of molar distalization, including:

  1. Teeth Used for Anchorage: Different anchorage setups can affect the extent of distal movement.
  2. The Type of Appliance Used: Whether the appliance uses a sliding mechanism or a friction-free mechanism plays a role.
  3. Patient Factors: Age, initial molar relationships, and the eruption of second and third molars all contribute to how effectively molars are distalized.

In studies that focus on growing patients, mean ages ranged from 11.2 to 14.9 years, which is crucial because the growth phase can significantly impact the effectiveness of treatment. For example, molar distalization is often more effective before the second molars have erupted. When second molars are erupted, more force may be required, and the treatment time may increase.

Amelogenesis Imperfecta

➡️ Represents a group of hereditary defects of enamel unassociated with any other generalized defects. It is entirely an ectodermal disturbance, since the mesodermal components of the teeth are basically normal.

➡️ Otherwise known as…

  • AI
  • Hereditary enamel dysplasia
  • Hereditary brown enamel
  • Hereditary brown opalescent teeth
AI can be inherited as an X-linked Autosomal Recessive or Autosomal Dominant condition

Prevalence: 1 in 700 to 1 in 15,000

Etiology:

  • Dental enamel is a highly mineralized tissue with over 95% of the volume occupied by unusually large, organized structures called the hydroxyapatite crystals.
  • The formation of these is controlled in Ameloblasts through the interaction of a no. of organic matrix molecules that include –
MMP20 (Matrix Metallopeptidase 20)
DSPP (Dentin sialophosphoprotein)

Develoment of Enamel:

➡️ 3 stages:

  1. Formative – deposition of organic matrix
  2. Calcification – Matrix mineralization
  3. Maturation – Crystallites enlarge & mature

Types of AI classification (Witkop and Sauk)

Based on clinical, histological & genetic criteria:

🔹 TYPE I HYPOPLASTIC

  • Pitted Autosomal dominant
  • Local Autosomal dominant
  • Local Autosomal Recessive
  • Smooth Autosomal dominant
  • Smooth, X-linked dominant
  • Rough Autosomal dominant
  • Enamel agenesis, Autosomal Recessive

🔹 TYPE II HYPOMATURATION

  • Diffuse Pigmented, Autosomal Recessive
  • Hypomaturation
  • Snow-capped teeth, X-linked
  • Autosomal Dominant

🔹 TYPE III HYPOCALCIFICATION

  • Diffuse Autosomal dominant
  • Diffuse Autosomal Recessive

🔹 TYPE IV COMBINATION TYPE

  • Hypomaturation – Hypoplastic with taurodontism
  • Hypomaturation – Hypoplastic with taurodontism, Autosomal Dominant
  • Hypoplastic – Hypomaturation with taurodontism, Autosomal Dominant

Clinical Features:

1) Hypoplastic – Enamel not formed to full normal thickness.

2) Hypomaturation –

  • The enamel can be pierced by an explorer point under firm pressure.
  • Can be lost by chipping away from the underlying normal appearing dentin.
  • Teeth normal in shape but exhibit a mottled, opaque white, brown-yellow discoloration.
  • Snow capped pattern – Zone of white opaque enamel on the incisal or occlusal third of crown.

3) Hypocalcified

  • The enamel is so soft that it can be removed by a prophylaxis instrument.
  • Yellow, brown or orange on eruption. Stained brown to black with time.
  • Rapid calculus apposition.
  • Coronal enamel lost with function except for the cervical portion which is mineralized better.
  • Autosomal Recessive – More severe.

Other Features:

  • Both dentition affected
  • Crown – Yellow to dark brown
  • Enamel might have numerous parallel vertical wrinkles or grooves.
  • Open Contact points.
  • Occlusal & incisal edges frequently abraded.

Radiographic Features:

Source: SlidePlayer
  • The enamel may appear totally absent.
  • When present may appear as a thin layer, chiefly over tip of cusps & on inter-proximal surfaces.
  • In some cases, calcification is so much affected that enamel and dentin seem to have the same radio density, making differentiation b/w the two difficult.

Histological Features:

  1. Hypoplastic: Disturbance in the differentiation/viability of Ameloblasts. Defect in matrix formation.
  2. Hypomaturation: Alteration in enamel rod & rod sheath structures.
  3. Hypocalcified: Defects of matrix structure & of mineral deposition.

Management:

  • Sealants/bonding
  • Prosthetic reconstruction
