 Function of mouth  External mouth  Internal mouth ◦ Oral vestibule ◦ Oral cavity proper ◦ Tongue ◦ Salivary gland  وظيفه دهن  قسمت خارجي دهن  قسمت داخلي دهن o دهليز دهن o حفره دهن o زبان o غده لعابيه CFHSTC Clin Perio Crse 0013

Functions of mouth وظيفه دهن 1. The first part of digestive system wherein mastication occur. 2. It receives food (ingestion) and break up the food into smaller pieces (digestion). 3. Takes part in respiration as well as in speech production 4. Lastly it conveys emotion 1. اولين بخش سيستم هضمي كه جويدن انجام ميشود. 2. اين غذا را گرفته و سبب پارچه ساختن آن ميگردد 3. در تنفس و توليد صدا حصه ميگيرد. 4. سبب رساندن احساسات ميگردد

 Composed primarily of the upper and lower lips  Lips separate from the skin by vermillion border از لب هاي پائيني و بالائي ابتدائي تشكيا ميشود لب ها از جلد توسط سرحد سرخ يا vermillion.

Philtrum Vermillion border Mento- labial fold Naso- labial fold Commissure Oral fissure Upper lip Lower lip

Divided into 2 parts: بدوبخش تقسيم ميگردد: 1. Oral vestibule 1. قسمت سرخ فمي 1. Oral cavity proper 2. قسمت حفره دهن

The Oral vestibule راهرو دهن A slit like space bounded: Laterally by cheek and lips Medially by the buccal and labial surfaces of the upper and lower teeth Posteriorly by the retromolar area يك فضاي شكاف دار وصل شده با: از قيمت جانبي با كومه و لب ها مياني توسط سطوح بوكل و لبيل دندان هاي بالائي و پائيني عقبا به ساحه retromolar

Ventral surface of the tongue Lingual Frenulum Sublingual fold Sublingual caruncle

Composed of: Anterior 2/3 (body)and Posterior 1/3 (root) Presence of lingual papillae: Filiform papilla Fungiform papilla* Foliate papilla Circumvallate papilla * (* that contains taste buds )

1. Parotid Gland: ◦ the largest of the 3 salivary gland ◦ Located anterior to the ear, extending from the cheek bone up to the lower jaw ◦ Parotid or Stensens’ duct opens at the oral vestibule opposite upper second molar 2. Submandibular gland: ◦ Located at the floor of the mouth posteriorly ◦ Whartons’ duct opens at the sublingual caruncle 3. Sublingual gland: ◦ Located at the floor of the mouth anteriorly ◦ The numerous ducts of SL gland open at the sublingual fold 1. غدوات پاروتيد: بزركترين غدوات لعابيه ميباشد به قسم قدامب گوش قرار داشته و از استخوان كومه تا به الاشه پائيني ادامه پيدا مينمايد. اين در مقابل آسياب بالائي دوم باز ميگردد 2. غدوات تحت الاشه : قدامي در كف دهن واقع است حفره Whartons به كارنكل تحت زباتي باز ميگردد 3. غدوات تحت زباني در كف دهن به شكل قدامي واقع است تعداد زياد غدوات زير زباني به sublingual fold باز ميگردد
