Dental and Oral Biology

Tigers have the longest canine teeth among all big cats, typically reaching about 3 inches in length. These massive teeth are evolutionary adaptations that enable tigers to grip and kill prey efficiently, with a bite force strong enough to take down large animals like deer and wild buffalo.

Dabur Red is a toothpaste brand positioned around keeping teeth strong and preventing dental problems. This tagline matches the brand's traditional Ayurvedic positioning focusing on gum health and strong teeth.

Non-sticky chocolate like Dairy milk causes less harm because it doesn't adhere to teeth for prolonged periods. Sticky chocolates and candies remain in contact with tooth enamel longer, increasing decay risk. Biscuits contain refined carbs that break down into sugars, promoting bacterial growth and acid production.

The root 'dent' comes from the Latin word 'dens', meaning tooth. This is seen in words like dentist or dental. 'Bad' is 'mal', 'joint' is 'arthr', and 'clean' is 'pur' or 'deterg'.

While dental disease is common in dogs, it's not accurate to say 'most' adult dogs have it. Studies show varying prevalence (30-80% depending on age and breed), but it's not a universal condition affecting the majority of all adult dogs.

Maximum bite force in humans is typically around 150-170 pounds for the back teeth, not 200 pounds. While some sources may cite figures around 200 psi, this is not the typical or maximum force that human jaw muscles can generate for chewing.

Chewing on bones provides natural dental benefits for dogs. The mechanical action helps remove plaque and tartar buildup, strengthens jaw muscles, and can reduce gum disease. Bones also provide mental stimulation and satisfy natural chewing instincts. However, cooked bones should be avoided as they can splinter.

Chewing on raw, appropriate bones helps remove plaque through mechanical action and provides mental stimulation for dogs. However, cooked bones should never be given as they can splinter and cause serious injuries.

White coating on a baby's tongue is oral thrush, a common yeast infection (Candida albicans) in infants. Diaper rash affects the diaper area, milk rash is different, and internal yeast infection would have other symptoms.

The dental formula for humans is 2123/2123, representing the number of each type of tooth in one quadrant: 2 incisors, 1 canine, 2 premolars, and 3 molars. This formula is counted for each quadrant (upper right, upper left, lower right, lower left).

Enamel is the hard, outermost layer of teeth that protects the softer dentin and pulp underneath. It's the hardest substance in the human body.

This is a joke/riddle referencing Rajinikanth (Rajni), known for exaggerated feats in Indian pop culture. The 'tooth powder to cement' transformation is absurd humor - the punchline is that Rajni's 'dental cement' became so strong it could build houses. Jayalakshmi is a cement brand, fitting the punchline.

Tiger canines are approximately 3 inches long, making them the longest canines of any big cat and crucial for their hunting success.

The correct answer is B because 'tooth and nail' is an idiom meaning to fight with great effort and determination. Bone, tongue, and tail don't complete this expression.
