The Hardy Advanced Technological Institute [5] is located in Ampara, Sri Lanka. [6] Founded in 1956 by Prof. Allen Hardy as the Technical Training Institute with aid from the Colombo Plan, Food and Agriculture Organization (FAO) and the Asia Foundation, it was renamed as Hardy Senior Technical Institute (HSTI) in 1967.

That is the total length of the alveolar arch is smaller than the tooth arch (the combined mesiodistal width of each tooth). The wisdom teeth (third molars) are frequently impacted because they are the last teeth to erupt in the oral cavity. Mandibular third molars are more commonly impacted than their maxillary counterparts.

Inflamed alveolar bone, unprotected and exposed to the oral environment after tooth extraction, can become packed with food and debris. Dry-socket typically causes a sharp and sudden increase in pain commencing 2–5 days following the extraction of a mandibular molar, most commonly the third molar. [51]
This system includes a horizontal and vertical component to classify the location of third molars (predominately applicable to lower third molars): the third molar's relationship to the level of the teeth already in the mouth, being the vertical or x-component and to the anterior border of the ramus being the horizontal or y-component.

Continuing Education Centre (CEC) and curriculum development units function under the Human Resource Development Centre of the University.These units provide extension services to the agencies in the TVET sector which are delivering training at NVQ Levels 1 to 6, in the areas of human resource development and curriculum development.
The mandibular third molar is the tooth located distally from both the mandibular second molars of the mouth with no tooth posterior to it in permanent teeth. In deciduous teeth, there is no mandibular third molar. For this tooth, there are great variances among third molars, and a specific of a third molar will not hold true in all cases.
A Mesio-impacted, partially erupted mandibular third molar, B Dental caries and periodontal defects associated with both the third and second molars, caused by food packing and poor access to oral hygiene methods, C Inflamed operculum covering partially erupted lower third molar, with accumulation of food debris and bacteria underneath, D The upper third molar has over-erupted due lack of ...
