c) Maxillary first molar
d) Mandibular first molar

The correct answer is C. Maxillary First Molar. 

A measurement of the crown buccolingually and mesial to the buccal and lingual grooves is greater than the measurement on the portion of the crown that is distal to these developmental grooves. Also, a measurement of the crown immediately lingual to contact areas mesiodistally is greater than the measurement immediately buccal to the contact areas. Thus, it is apparent that the maxillary first molar crown is wider mesially than distally and wider lingually than buccally.

#Dentosphere's GEMS - MUST KNOW POINTS IN ORAL MEDICINE AND RADIOLOGY for MDS ENTRANCE EXAMINATION

1. The jugulodigastric lymph node is the most common lymph node involved in tonsillar infections and oral cancer, and hence, should be thoroughly examined while examining the cervical group of lymph nodes.

2. Many drugs can produce gingival swelling – most commonly implicated are phenytoin, ciclosporin and calcium channel blockers.

3. The most common salivary lesion causing a swelling is the mucocele, usually caused by extravasation of saliva from a damaged minor salivary gland duct and seen in the lower labial mucosa, sometimes caused by retention within a gland.

4. Sialadenitis most commonly manifests in the parotid gland (parotitis). The organisms most commonly isolated from bacterial ascending sialadenitis are Alpha-haemolytic streptococci, such as Streptococcus viridans and Staphylococcus aureus , the latter frequently being penicillin-resistant.

5. Amalgam tattoo is the most common cause of a single patch of macular blue-black pigmentation, does not change significantly in size or colour, is painless and is usually seen in the mandibular gingiva or at least close to the teeth or an apicectomy where there has been a retrograde amalgam root end filling.

6. Ramsay–Hunt syndrome, caused by varicella-zoster virus infection, which allegedly involves the facial nerve at the geniculate ganglion.

7. Oral Squamous cell Carcinoma (OSCC) is among the 10 most common cancers worldwide: around 300 000 new cases worldwide annually, amounting to around 3% of total cancers.

8. Behçet syndrome (BS), sometimes also known as Adamantiades syndrome and Behçet disease, is a potentially lethal condition. It is a triple symptom complex of aphthous-like ulcers with genital ulceration and eye disease (especially iridocyclitis), though a number of other systemic manifestations may also be seen, characterized by necrotizing vasculitis.

9. Bell palsy is most commonly caused by inflammation and oedema in the facial nerve canal, usually in the stylomastoid canal, causing demyelination of the facial nerve (seventh cranial nerve) usually due to HSV (Herpes Simplex Virus).

Dental Practice Management - Importance of Appointments

Dental Practice management is a broad topic that includes setting up a dental clinic, hiring of adequate number of staffs that are well versed with the work they are supposed to do in an efficient manner and in perfect harmony to increase the net revenue of the clinic, materials supply management, patients' record management, patients' appointment management, cashflow management and many more. Let's discuss about the importance of appointments for better efficiency and maximizing the revenue in least possible chairside time.

Not every dentist is well acquainted with the managerial skills that is necessary to run a dental clinic. Some acquire it naturally on the go after establishing a dental clinic and some struggle for years due to lack of the skill and experience too many patients in some particular days and not a single patient some unfortunate day. More often than not, once a dental clinic is well-established and with good track record of providing good dental care, there will be problem of having too many patients rather than having too few patients. This is where the one aspect of dental practice management - Appointment system becomes of paramount importance. 

Though, it seems cumbersome to keep records of appointment time and follow that strictly, it has infinite perks. Some advantages of keeping strict patient appointments are:

A. You can give enough time to each patient. You need not hurry that there are too many patients at  a particular time. Your workload is relatively constant at a pace you have set for yourself. The inter-patient time gap is minimized and patients examined/treated per unit time rises several folds. 

B. You can set different time hours for different types (age groups/profession)   of patients and prepare your instruments for the same. Charging a bit more for treatment provided during off-hours for employed patients who cannot take a leave is not unethical at all. You provide a great value of service and get increased return for yourself. 

C. You can reduce the number of staffs and Dental Chairs required as per the workload and minimize unnecessary expenditure. False indication of patient overload and temptation to add another dental chair and dentist is also avoided. Adding up dental chairs and dentists without actually having sufficient patients all the time would be hazardous to your practice and sometimes you have to sell the equipments at a great loss or downsize on staffs.

D. Better Patient Care: Each patient feels that he is important for you because you have set a separate time for him. Your dedication to him and meticulous clinical care will make you a trustworthy clinician for him.

E. You can actually reduce the clinic opening hours. When you figure out the number of patients coming everyday, you can set your opening hours as per the requirement.
