Dentin is a Light Yellowish Viscoelastic material made up of Inorganic (Hydroxyapetitie) and Organic (collagenous fibrils and mucopolysaccharides) material which is harder than bone. Dentin thickness is 3-10 mm based on the location. Dentin is made up of dentinal tubules which are S shaped and perpendicular to Dentino enamel junction and Cementoneamel junction. Dentin is […]
Abnormalities in physiologic stages of tooth development

Self Correcting Anomalies in Dentistry
Self correcting anomalies are termed as Transient malocclusion, these are not true malocclusion’s but mimic malocclusion during the normal development of dentition and occlusion. they do not need any corrective measures but get corrected themselves as they pass through the developmental stages . Self correcting Anomalies are classified based on the stages of tooth development […]
Differences between Maxillary and Mandibular Incisors – Anatomically
Incisors are the first erupting teeth in both the Deciduous and permanent dentition. There are four Incisors in the Maxillary arch and four Incisors in the Mandibular arch in both deciduous and permanent dentition. The Deciduous Mandibular Central Incisors are the First Teeth to erupt into the oral cavity at an Age of 6 – […]
Embrasures
Embrasures Definition: Two teeth in the same arch are in contact, their curvatures adjacent to the contact areas form Spillway spaces called Embrasures. A Gap between 2 adjacent teeth, as the teeth curve away from the contact area. The Embrassures are usually V-shaped valleys and provide a spill way for food to escape during chewing […]

The pathway of mandible during chewing is referred to as chewing cycle. Characterized by opening, closing, retrusive, protrusive & lateral jaw movements The chewing cycle can take many forms; classically tear drop shape when viewed in frontal or saggital plane There are about 15 chews in a series from the time of food entry until […]

These muscles help mainly in the movement of the mandible and not the maxilla as maxilla is an integral part of the skull and the mandible being the only movable bone in the skull. The muscles help in moving […]
