The inferior alveolar nerve is also known as inferior dental nerve.  It gives off a motor branch that supplies to mylohyoid muscle and anterior belly of digastric. Then it enters mandibular foramen and travels through the inferior alveolar canal. From inferior dental canal it supplies to mandibular third molar, second molar, first molar, and second premolar.   From the level of the second premolar, it moves forward as mental nerve and exits through mental foramen.  The mental nerve supplies sensory nerve fibres to the chin and lower lip of that side. Within the mandible after mental foramen, it moves forward as incisive nerve and gives sensory supply to mandibular incisors and mandibular canines of that side. 

Resin Sealants   Properties These are light activated unfilled resins. Most are relatively viscous and do not set through loss of solvent. They set either by chemical or light activation.

Maxillary nerve is the second division of the trigeminal nerve. It divides into several branches. You will read here about those that are related to dentistry below.

Effect of Diabetes on Osseointegration and Dental Implants The tenacious hyperglycaemia in diabetic people, hinder osteoblastic activity and modifies the response of parathyroid hormone that adjusts metabolism of Ca and P, decreases collagen synthesis during callus formation, induces apoptosis in lining cells of bone and increases osteoclastic activity due to untiring inflammatory response. It also stimulates deleterious effect on bone matrix and reduces growth and build-up of extracellular matrix. The subsequent result is reduced bone formation during healing. Type -1 diabetes (insulin dependent) causes decreased bone formation, as well as reduced bone mineral density and higher bone resorption while Type -2 diabetes (non-insulin dependent) produces normal or greater bone mineral density in some patients. It has been detected that insulin not only diminishes the harmful effect of hyperglycaemia by controlling it but also stimulates osteoblastic activity.

The pulp of a tooth lies within its mass. It may be insulted due to various types of injuries and may need to be protected during the treatment. There are varieties of materials available for use. They show different properties and can be used in different conditions with their own advantages and disadvantages. These materials are as follows.

Abrasion It is loss of the tooth substance because of the friction with a foreign substance.The area affected by abrasion are smooth and usually in C shape, more wide than deeper. Clinical Features   These are usually facio-cervical concavities that are more broad than deep and can be associated with an abrasive diet. They are usually found on prominent surfaces of the teeth in the dental arch such as canines, premolars, and mesio-buccal aspects of first molars.  They may affect several teeth in a row with a “band” of abrasive damage. Sometime they may cause hypersensitivity which means the tooth or teeth may have pain while drinking hot or cold beverages like hot coffee or a cold drink. Figure 1 . Abrasion: note the concave smooth cavities in the cervical regions of upper and lower teeth. Causes of Abrasion The reason may be one or a combination of following factors.
