Dental implants are screw shape devices used for anchorage for dental prosthesis—crown, dentures inside the mouth. They are made of titanium alloy and serves as a replacement for the root of missing tooth. They are used in adults of all ages for the replacement of teeth missing due to trauma, decay, or if an individual born without teeth. Once they are placed in the jaw bone, they form a bond with the bone and provide rigid base support for artificial teeth replacement. They are indicated in adolescents once the facial growth is completed—16 years for girls and 18 years for boys. Dental implants result in the restoration of the masticatory and cosmetic function of the individual so that the individual can enjoy his life confidently.

Q. How much time does it take to replace the teeth with the help of a dental implant?

A. Every patient depending on their need, medical and dental history and the health of supporting jawbones requires a customized treatment strategy. It can be 4 to 6 months for simple cases and up to 1 year for complex cases.

Q. Is dental implant treatment safe?

A. Dental implant is a safe and effective procedure for the last 30 plus years. The implant dentist should educate the patient regarding the effect of certain medical conditions and habits like smoking which affect the success and prognosis of dental implants. Qualified dentists with highly competent skills will be able to manage the complications if any arises.

Q. Is dental implant a painful procedure?

A. With the help of good anaesthesia the implant placement is relatively painless and the use of analgesic postoperatively reduces the discomfort and pain associated symptoms. Usually, patients return to their day-to-day activity from the next day post-implant placement.

Q. What are the steps for dental implant treatment?

A. Dental implant requires following steps:

• Pre-treatment examination involving oral cavity examination, X-rays, and 3-dimensional evaluation of bone quantity and quality. Design a treatment plan specific to the situation.

• Dental implant placement under anaesthesia and management of post-operative symptoms like pain, mild swelling, and discomfort by the use of medicine.

• It will take few months (3 to 6months) so, that firm bond formation between implant and bone. During the healing phase, soft biting is allowed to prevent premature implant loading.

• After implant healing and abutment connected to the implant fixture and a dental crown will be attached to it.

• Maintenance of good oral hygiene and periodic check-up is required for the long-term health of the implants.

Q. What about dental implants vs fixed bridge?

A. Dental fixed bridge requires grinding of two adjacent teeth to provide support for the bridge for the missing tooth while a Dental Implant will be placed in the site of missing teeth without grinding the adjacent teeth. The ground teeth underneath the bridge have also become prone to decay and bone loss. So dental implants will be an effective way of restoring the natural smile.

New Delhi: The Union Ministry of Health and Family Welfare announced that the vaccination drive will be halted for two days, i.e., February 27 and 28, on account of a software change necessary for the second phase of vaccinations. The second phase of the Covid vaccinations will begin from March 1 across the country.

The second phase of the Covid-19 vaccination drive is for people aged 60 years and those above 45 years with co-morbidities. The two-day pause comes at a time when India is being criticized for a slow vaccination process. The vaccination drive in India was started on January 16 and the first jabs have been given to healthcare workers, followed by frontline workers like police personnel, people of the armed forces, municipal workers, teachers, etc.

A high-level meeting was also conducted with States and UTs to inform them about the 2.0 version of the digital platform Co-WIN.

“The States and UTs were explained the basic features of version 2.0 of the digital platform Co-WIN. Private sector hospitals will be involved as Covid vaccination centres to harness their potential to expand the vaccination capacities,” stated the Government of India.

New Delhi: A team of doctors from a Mumbai hospital gave a fresh lease of life to a 10-year-old girl who had accidentally swallowed a large metallic pin with a sharp end two years ago. A team led by ENT doctors Dr Kshitij Shah and Dr Shalaka Dighe, ably supported by paediatric pulmonologist Dr Sagar Warankar and an anaesthesia team led by Dr Pramod Kale, performed a successful surgery at the hospital to remove the pin from the girl’s lung. The patient recovered and was discharged within 48 hours.

Naira Shah (name changed) from Mumbai had accidentally swallowed the metallic pin two years ago. An X-ray of the abdomen had failed to reveal the foreign body and the incident was forgotten about, until Naira started complaining of a dry cough and was taken to Zen Multispeciality Hospital for further investigations.

“To our utter surprise, an X-ray of the chest revealed a metallic foreign body in the lower airway on the left side. A CT scan of the chest was done to precisely locate the foreign body. After an initial attempt at removal of the foreign body by flexible bronchoscopy, a decision was made to perform a rigid bronchoscopy,” said ENT surgeon Dr Kshitij Shah.

“Rigid bronchoscopy is a procedure done to gain access to the patient’s airway using a hollow metallic tube under general anaesthesia. The foreign body was successfully removed without any complications and without an external scar on the body after an hour-long surgery,” informed ENT surgeon Dr Shalaka Dighe, adding, “The child was hale and hearty in a couple of hours after surgery. Failure to remove the foreign body via bronchoscopy would have meant a very morbid open surgery (thoracotomy) to remove it.”

“For over 1.5 years, Naira (name changed) was fine and did not encounter any problems. But suddenly she started coughing. We panicked, feared Covid and took her to Zen Hospital. We are thankful to Zen Hospital for promptly treating our child. We urge other parents like us to keep sharp or metallic objects like pins or coins away from their children,” concluded the patient’s father, Sanjiv Shah (name changed).

Mouth ulcers are quite common in all age groups and can make regular activities such as eating, drinking, and talking very uncomfortable. However, mouth ulcers can be cured with antimicrobial or painkilling mouthwash, gel or spray. However, if the ulcers persist for several weeks even after treatment, one must not ignore the signs as it may indicate a cancerous growth. There are many signs of mouth cancer but red sores that do not respond to treatment or heal is a telling sign. Lifestyle habits such as drinking alcohol or consuming tobacco—both smoked and smokeless—can cause cancer of the mouth. Besides human papillomavirus (HPV), known to cause sexually-transmitted infections (STI) and cervical cancer, can also cause mouth cancer. HPV-affected mouth cancer is seen in the soft palate, tonsils, base of the tongue, and pharyngeal wall areas.


1. Persistent and unexplained lumps in the mouth or the neck

2. Unexplained loose teeth or sockets

3. Unexplained, persistent numbness on the tongue or lips

4. White or red patches on the lining of the mouth or tongue

5. Changes in speech like lisp

The types of mouth cancer are categorised by the type of cell it starts to grow in. Medically it is known as carcinoma. The most common type is squamous cell carcinoma that affects 9 out of 10 cases of mouth cancer.


1. Adenocarcinoma in which cancer develops inside the salivary glands

2. Sarcoma in which cancer develops from the abnormalities in cartilage, bone, muscle, or any other tissue

3. Oral malignant melanoma in which cancer starts in the cells that produce skin pigment (melanocytes). They often bleed and appear as dark, mottled swellings

4. Lymphoma in which cancer grows from cells in lymph glands

Mouth cancer as well as treating it can cause complications and affect the appearance of the mouth. Besides, it can cause dysphagia (problems with speaking and swallowing). Dysphagia can be a serious complication. If a small piece of food enters the airways when you try to swallow and gets lodged in the lungs, dysphagia may lead to aspiration pneumonia (a kind of chest infection).


Cancer of the oral cavity (lips, tongue, buccal mucosa, tonsils, and palate) can give rise to various complications that include difficulty in eating, speech, alteration in voice, inability to open mouth fully, pain in the ear, and bleeding if not treated in time.

Easy lifestyle changes and preventive measures including but not limited to the following can help in preventing mouth cancer in most people:

1. Quit smoking or consuming smokeless tobacco as well as alcohol

2. Get vaccinated against HPV

3. Using a condom during oral sex to lower the chances of HPV infection

4. Visiting a dentist regularly for screening

5. Consuming a balanced diet of fresh vegetables (especially tomatoes), citrus fruits, olive oil, and fish with omega-3 fatty acids

If diagnosed early, mouth cancer can be completely cured in 9 out of 10 cases using surgery.

While certain southern states in the country have initiatives in place for supporting patients with rare diseases, the Centre needs to take a more serious note of the issue, especially regarding a sustainable funding mechanism for Group 3 rare disease patients in India.

With the Union Ministry of Health & Family Welfare likely to finalise the long pending National Policy on Rare Diseases and notify it by March 31, serious concerns are now being raised by patients and support societies that the revised policy may meet the same fate as the earlier National Policy for Treatment of Rare Diseases 2017 without any provision to support the treatment of patients diagnosed with Group 3 disorders like lysosomal storage disorders (LSDs).

Patient advocacy groups like the Organisation for Rare Diseases India (ORDI) and Lysosomal Storage Disorders Support Society (LSDSS) are concerned that the Union Ministry’s proposed crowdfunding mechanism may be inadequate, just like the provisioning under the umbrella scheme of Rashtriya Arogya Nidhi (RAN), to provide immediate treatment support to patients with these life threatening conditions—categorised as Group 3 disorders—and particularly those for which Drugs Controller General of India (DCGI) approved therapies are available.

According to patients who have been long awaiting support to start treatment, the Union of India should make immediate necessary provisions for all orphan diseases, as has been done by many other countries.

In the absence of a National Policy on Rare Diseases, a few states in the south have sought support from the Union of India to provide a matching grant in order to sustain the ‘proof of concepts’ shown in providing the much-needed funding support to patients diagnosed with life-threatening rare disease conditions, including LSDs.

Group 3 disorders are a category of rare diseases like Pompe disease, Gaucher disease, Fabry disease and MPS I which are serious, chronic, debilitating and fatal disorders, often requiring long-term, specialised treatment and chronic management and often causing severe handicaps and a catastrophic impact on the entire family. This group of rare diseases particularly impact children, causing 35% of deaths before age 1, 10% between the ages of 1-5 years and 12% between 5-15 years.

Karnataka has been engaged with this programme for close to five years now, providing treatment support to such children. Karnataka has reportedly spent around Rs 40 crore on providing treatment and other life support to the patients diagnosed with rare diseases.

Kerala and Tamil Nadu have also allocated funds from the state exchequer to provide life-saving therapies to a few of these children. In September 2020, the Kerala state government started an initiative to enrol two toddlers suffering from Pompe disease for the life-saving Enzyme Replacement Therapy (ERT) at the Government Medical College, Kozhikode. The infusion therapy was started following an order by a division bench of the Kerala High Court hearing a writ petition filed by the patient advocacy group LSDSS, set up to fight the cause of patients suffering from rare diseases across the country. Under the order of the Kerala High Court, the Centre allotted an amount of Rs 1.5 crore while the state sanctioned another Rs 50 lakh for the treatment of the two patients. Interestingly, members of the Kerala High Court Advocates’ Association, following an appeal by the High Court, also mobilised an amount of Rs 5 lakh for the treatment of the rare disease patients.

As for Tamil Nadu, in March 2020, the Madras High Court directed the Centre to pay Rs 4.4 crore for the treatment of patients with rare disease patients in the state. In the same order, the High Court also instructed the Tamil Nadu government to allocate Rs 5 crore for the treatment of the 11 rare disease patients in the state following a public interest litigation filed by the Delhi-based LSDSS in the Madras High Court, seeking financial aid from the government for the treatment of rare disease patients in the state of Tamil Nadu.

The health departments of each of the three states have also written to the Union of India to support the initiative by providing matching grant in order to provide sustenance to the programme besides allowing a scope to expand the treatment support to other eligible patients awaiting funding support.

With Rare Disease Day celebrated worldwide on 28 February each year to raise awareness about the issue, it has been sincerely requested that the government address the urgent need for a sustainable funding mechanism for Group 3 rare disease patients in the country.

Spread of new Covid-19 mutants is preventable through caution: Experts

Continue wearing masks, follow social distancing and get yourself vaccinated if you have the chance, advise top doctors, as the country sees a spike in coronavirus cases again.

Shalini Bhardwaj



With the new mutants of the coronavirus entering India and certain states experiencing a spike in new cases, concerns about the infection spreading widely have come up again. However, in an exclusive interview with The Sunday Guardian, Dr Anjan Trikha, Professor of Anesthesiology, Pain and Critical Care at AIIMS, and Dr Rakesh Mishra, Director of CCMB, say that people can keep themselves safe from the surge if they stop taking safety norms for granted and follow all precautions.

Dr Rakesh Mishra
Dr Anjan Trikha

Q: Do you think the new strain could be more dangerous for our country?

Dr Rakesh Mishra: Normally, new strains are just another variation of the coronavirus. We have recently documented close to 7000 mutations in Indian isolates. While most of them won’t be seen again, others may acquire the status of a variant if they spread rapidly, but that doesn’t mean they are dangerous. They may still be responding to the vaccine, may be asymptomatic and have a similar mortality rate. But studies show that these variants aren’t more dangerous than the existing one, just sequentially different. There may be new infections arising from them but if precautions are not taken, new mutations might occur and we may end up with something more dangerous than the existing situation. So, we must prevent the spread of any disease. So far, variants are not clinically different or problematic but it can happen in the future.

Q: What can be the reason behind the spike in cases in Maharashtra and Kerala?

Dr Rakesh Mishra: The most probable reason is that people have taken the norms for granted now and are not following precautions like wearing masks and maintaining social distancing. This may have caused the sudden spread. We will know when the Maharashtra sequences will be available. They are being processed at NIB and NCC. In Kerala, no new variant is emerging, which means the existing one is spreading at a higher rate. If you don’t prevent person-to-person spread, cases will rise. You don’t need a new variant for super spreading to happen. The new variant doesn’t overcome the immune response, thus there are less chances of re-infection. But this spread is preventable through more caution.

Q: Do we have enough capacity to fight against new mutated viruses?

Dr Anjan Trikha: When the first patient of the existing variant came to me in March, we had no idea about how to cure or prevent this disease. We had no medicine or any idea except from what we learnt through social media trends that came from Italy, China or Europe. Whatever came was frightening, but we did fight it. If we intend to fight a viral disease, we can, so there is nothing alarming about it. We must keep the fundamentals in mind and teach it to our elders and children. We cannot afford to be inside for another year. Inform everyone that the disease is not over yet. Viruses are known to mutate and you will find me wearing a mask in 2022 too.

Q: Are the vaccinated ones still a threat to those who haven’t been vaccinated yet?

Dr Anjan Trikha: India is a land of controversies, so be cautious against rumors. Nobody knows about efficiency and efficacy apart from the doctors who are administering it. If the government is giving you a vaccine, believe that it will prevent you from catching severe infections. So, you may get infections or you may not, but if you do, you will not get serious infections if you have already been vaccinated. Have faith in the government and do get vaccinated. The government has a plan to get all people vaccinated. You have seen what is happening in Maharashtra, Kerala and Dubai. They decided to open up for tourism and then had to shut it down. My trauma centre still is open for Covid patients and we have empty beds. This is what happens in a pandemic — you need to wait and be prepared for anything.

Q: What message would you like to give regarding the rise in cases?

Dr Rakesh Mishra: We are going through an unprecedented situation of this century. In comparison with other countries, India has performed extraordinarily in terms of active cases, mortality rate, etc. But we have paid our price for it, gone through lockdowns and severe crises of reverse migration. We still need to practise precautions like wearing masks and social distancing. Secondly, go for vaccination confidently and as quickly as possible. If we don’t do so, we will leave the enemy half dead and it will bounce back just as it did before. I may be asymptomatic but what about my family members and seniors who have comorbidities? So, we must be responsible and follow precautions and take the vaccine because they are tested and safe. A lot of people have been vaccinated and none of them have gone through any serious consequences. But after getting vaccinated, do wear masks because 10%-20% of you may not be affected by the vaccine or the vaccine might take a month or so to set in full force. New variants may also prove the vaccine to be less effective on them. We are almost there but have not won yet.

Q: Do you think vaccinations should be available for common people now?

Dr Anjan Trikha: Opening up the vaccines for common people is crucial but should be done in time. First, it has to be given to the healthcare workers, then to the frontline workers, then the elderly above 50 years of age who may have comorbidities and then, finally, to everyone else. We must remember that the vaccine has also been licensed for emergency authorised use only. Studies are still coming out about whether to give it to children below 17 years of age or pregnant women. We assure you that the government will open it for all soon, but we must remember that the vaccines need to pass through guidelines and rules. The Drug Controller office and FDI Bhawan have a lot of experts who scrutinize the data for the vaccine and then approve it. It is just that everything needs to be managed the right way. If you are called or messaged to inform you that your chance has come, go get vaccinated. Tell the doctor if you are allergic so the doctor decides whether to give you the vaccine. There may be some adverse reactions after taking the vaccine, just like with any other vaccine. Also, follow social distancing and wear masks because we are still susceptible to the disease.

The AIIMS facility of Patna has given consent on the motion to terminate its faculty members for lacking basic qualifications at the time of their recruitment.

These members include Ajit Saxena, professor and head of the pathology department, Sushmita Das, associate professor in the microbiology department and Alok Ranjan, an assistant professor in the department of community and family medicine. One of them had even been promoted during the August-September 2017 assessment promotion scheme of the institution.

The government body of the institute made no comments on the decision it took on Thursday regarding the matter.

According to a media report, the matter goes back to 2011 when the institute advertised for faculty recruitment in December. However, the advertisement had clearly mentioned that the appointment required a PG degree recognised by the erstwhile Medical Council of India (MCI), now National Medical Commission (NMC). However, two of the faculty members only had postgraduate degrees in zoology, a non-medical subject, during their appointment in 2012-2013. Meanwhile, although Ranjan had the required qualification, he lacked a Ph.D. degree at the time of his recruitment.

Sources informed The Sunday Guardian that the assistant professor had fulfilled the required criteria within nine months of his joining (September 7, 2012) and submitted his Ph.D. degree from a USA-based university. However, the other two still lacked the required qualifications.

A total of 19 faculty members were scrutinised regarding the matter. Some of them criticized the penalty which they faced eight years after the fault committed by the Selection Committee, while a few have moved the court against the disciplinary action taken by the institute.

Sources informed that an IPS officer blew the cover of the terminated professors while Kishore Yadav, Deputy Director (Administration) of AIIMS-Patna, brought the matter to light in 2013.

Later, the Vikas Arya committee, constituted by the Union Health Ministry in 2014, also marked the appointments faulty. Finally, a five-member high-powered committee consisting of directors of AIIMS-Bhubaneswar and AIIMS-Patna also found the recruitment of the three members bogus.
