Pretend you are a teacher preparing a quiz for the text I will provide. 
            Each quiz question should follow the format below. 
            Ensure that you carefully recheck the questions and answers for accuracy. 
            The output should be a ready-to-use list of dictionaries for the Python eval function:

            [

                    "question": "WRITE THE QUESTION HERE",
                    "options": ["A) OPTION_1", "B) OPTION_2", "C) OPTION_3", "D) OPTION_4"],
                    "answer": INDEX_OF_CORRECT_ANSWER_IN_OPTIONS_LIST,
                    "explanation": "EXPLAIN WHY THE ANSWER IS CORRECT"

            ]

                  Single rooted teeth                     Multirooted teeth 
The undivided portion of the root is called:Root Trunk. 
B)  Micro-anatomy of the tooth: 
 
 
 
 
 
 
 
Three calcified tissues:  Enamel , 
Dentin,Cementum + One soft specialized 
connective tissue: Pulp. 
 
11 
 
Anatomy Of The  Pulp Cavity 
The pulp cavity Consists of Two Parts 
1 - Pulp chamber  + pulp horns 
2 - Root canal  + apical foramen + accessory canals(Lateral canals) 
Note: Many roots may be formed with more than one canal, which may end in a common 
foramen. 
 
Junctions Of Tooth Tissues 
 
There Are Three Sites Of Junction        
1-Cemento-enamel junction (CEJ) 
2- Dentino-enamel junction (DEJ) 
3- Dentino-cemental junction (DCJ)                          
The Periodontium  
Is The Investing And Supporting Attachment System Of Teeth.  
It consists of: 
Two Soft Tissues and Two Hard Tissues 
Soft Tissues 
1- Gingiva  
  CEJ 
DEJ 
DCJ 
Dentin 
Pulp 
Cementum 
12 
 
The Oral Mucous Membrane, Which Covers The Neck Of The Tooth And Part Of The 
Alveolar Bone. 
2- Periodontal Ligament  
Strong Ligament that Attaches The Tooth To The Alveolar Bone. 
Hard Tissues 
1- Cementum  
Covers The Anatomical Root of The Tooth. 
2-Alveolar Bone  
The Bone of The Jaw That Surrounds The Root of The Tooth. 
Functions Of Teeth 
1- Mastication: It is the most important function of the teeth. The teeth are designed to 
perform this function.  
 
Incisors            Canine            Premolars           
 
Molars
 
   
 
 
Chisel like       Wedge like                                                                                                                        
Incisors:Cutting or incising.                                        Canine: Cutting and tearing.  
Premolars: Tearing and grinding.                               Molars : Grinding. 
2- Appearance:  
1-Well arranged clean teeth with proper alignment give nice appearance to the face.  
2-Teeth give support to the facial expressions. 
3- Speech: Teeth are important for clear pronounciation and for production of sound. 
4- Growth of jaws: The teeth play a role in the growth of the jaws in some periods of life.

Tooth Surfaces 
Each Tooth Has Five Surfaces Like A Box With 4 Sides And A Roof. These surfaces are: 
Facial, lingual, mesial, distal and masticatory (functioning) surfaces. Some of the surfaces 
are identified by the relationship to other orofacial structures. 
F=Facial 
L=Lingual 
M=Mesial 
D=Distal 
 
FACIAL: LABIAL TOWARDS THE LIP FOR ANTERIOR TEETH. OR 
BUCCAL: TOWARDS THE CHEEK FOR POSTERIOR TEETH
