Query from a Reader

Dentinal fluid filling the dentinal tubules in human tooth is basically-
a. pulpal exudate
b. odontoplastic fluid
c. transudate of plasma
d. bacterial exudate

Ans: Is a Odontoblastic fluid - a modified version of transudate. 

Q - neural tissue growth completed by
1) 6-7 yr
2) 10-12yr
3) 15-17 yr
4)18 yr

at the max by 10 to 12 years. Especially in CNS. PNS may take a little longer

Q- pH remain constant for period of time after consuming sucrose
1)120 min
2)30 min
3)60 min
4) 20 min

This is tricky. Unless the system - blood, sugar, plaque is mentioned, answer may be incorrect. 

Q- most common malignant bone tumor in children
2) Ewing sarcoma

Osteosarcoma - world wide 

Q- function of 20% koh for candida albicans staing
1) it stain hyphe
2) it dissolved epithelium background
(Main function) pls tell ....clerify ?

KOH Dissolves background material like debris including shed cells

Q- fusion of two palate shelves start
1) 6 week
2)10. Week
3) 8 week
4) 12 week

by 6th week process is initiated, 

Q- proprioceptive receptor present in dental pulp ?
1) few receptor present
2) not present at all
3) present 

The free nerve endings in pulp, as such are devoid of receptors. Hence, in the pulp, no stimuli- hot, cold or any such stimuli are being interpreted as pain as pain receptors (nociceptors) are only present and possibly few mechanorecptors are only present. Hence answer is not present at all...

Objective: Social networking sites (SNS) are emerging as an alternate teaching resource. The reach and access characteristics of SNS for a noninstitutional, academic blog in an Indian setting has not been documented and this manuscript aim to address this lacunae.Materials and Methods: A blog for oral histology, an integral basic dental subject and its Facebook promotional page was created. The access characteristics were observed using Google analytics. The Facebook promotional pages of the blog access characteristics are presented. Results: A total of 582 people visited the blog during the study period. Majority of them used Google Chrome from desktop/laptop to access the blog. There were 2723 page visits in all. Visitors from 36 countries and 99 cities across the globe accessed the blog. In all through Facebook, the promotional page reached 36,543 people. The total number of people engaged through Facebook promotion page was 10,757. Conclusion: Access characteristics of the noninstitutional, academic blog have been described for the first time in dentistry. The lessons learnt through this exercise would be helpful in designing e-mentoring courses as well promotional pages of such events in the future. The necessity of making the mentors and students to adapt to e-learning and digital learning resources before drawing such programs is highlighted.

Over All

The muscle involved in incisor clenching is the
Lateral pterygoid
The deciduous teeth erupt generally in a
Anterior - posterior sequence
The most common permanent teeth eruption in maxilla is
The difference between mesiodistal diameter width between premolars and deciduous molars is referred as
Leeway space
Curve of Spee is in a
Saggital plane
In a normal dentition, teeth are placed __________ degrees to the horizontal plane
Balanced occlusion is given by
Thielemann’s formula. Explanation  Balanced occlusion is ( condylar guidance*incisial guidance)/ ( curve of Spee* cusp height* plane of occlusion)
Mesiodistal inclination of the teeth is lowest with
Mandibular canine. The inclination is 0 degrees and maximum inclination is seen with maxillary canine and about 17 degrees. Similarly the minimum faciolingual inclination is about 5 degrees with maxillary first premolar and 28 degrees in maxillary central incisors.
The total number of possible occlusal contacts are
The process of swallowing requires a coordination of at least
20 muscles
The presence of overjet in molars prevents
Cheek biting
The supporting cusps are
Lingual cusp of maxilla and buccal cusp of mandible teeth
Multiple working side contacts are seen as a part of
Group function
