Dental Caries

a. Theory of Dental Caries
According to โ€œCaries Balance Conceptโ€ porposed by Featherstone, dental caries not only caused by single factor but also multi-factor. Dental caries caused by interaction between pathologic factors and protective factors. Pathologic factors include bacterial, poor diatery habits and xerostomia then protective factors include saliva, antimicroba, fluoride and good diatery habits. When the pathologic factors is stronger than protective factors so that caused dental caries.
b. Local factors caused Dental Caries
Host (teeth), substrat(carbohidrate), agent(bactery), time
c. Pathogenesis of caries
Pellicle formed a few minutes after dental cleansing. Pellicle is organic material that coating all cavity surface include hard tissue(teeth) and soft tissue as a place of accumulation and colonization of bacteria especially Streptococcus mutants. Streptococcus mutans change the carbohidrate into acid. When the local pH below 5.5 causes demineralization of tooth surfaces. Demineralization is a process releasing the crystal hydroxyapatite from the teeth to form dental caries

GIGI BERLUBANG/KARIES GIGI

a. teori gigi berlubang(karies) :
Gigi berlubang disebut juga dengan karies gigi. Menurut โ€œcaries balance conceptโ€ oleh Featherstone karies gigi tidak terbentuk karena satu faktor saja melainkan karena multifaktorial berupa interaksi antara faktor patologi dengan faktor protektif. Faktor patologi berupa bakteri, makanan, dan xerostomia(kurangnya sekresi saliva) sedangkan faktor protektif berupa saliva, antimikroba, fluoride. apabila faktor patologi lebih kuat maka akan terjadi karies gigi.
b. Faktor lokal pembentuk karies :
Host(gigi), substrat(makanan), agen(bakteri), waktu.
c. Patogenesis(proses) terjadinya karies :
Setelah pembersihan gigi maka beberapa menit kemudian terbentuk pelikel(Material organik yang melapisi seluruh permukaan kavitas oral termasuk jaringan keras(gigi) dan lunak. Kemudian terjadi interaksi antara pelikel dengan bakteri terutama Streptococcus mutans akhirnya berakumulasi dan berkoloni. Dalam periode waktu tertentu apabila tidak dilakukan pembersihan gigi maka koloni bakteri S. Mutans akan memfermentasikan karbohidrat(sisa makanan yang menempel di gigi) menjadi asam. Terbentuknya asam akan menurunkan pH plak sehingga akan memberikan suasana asam disekitar gigi. Kemudian ion asam bereaksi dengan fosfat pada saliva dan plak/kalkulus, sehingga akan terjadi proses demineralisasi yaitu terlarutnya kristal hidroksiapatit gigi sehingga terbentuklah karies gigi.

Histology of enamel and Dentin-Pulp Complex - Striae of retzius : garisโ€“garis paralel thd permukaan enamel, memanjang dari DEJ hingga ke permukaan luar dari enamel. - Enamel Lamella : nampak seperti garis juluran bergerigi yang masuk permukaan bebas.
- Enamel tuft : juluran yg memasuki email dar batas dentin-email.
- Enamel spindle : tubuli yang bercabang & meluas kedalam email. - Striae of retzius : The striae of Retzius often extend from the dentinoenamel junction to the outer surface of enamel, where they end in shallow furrows known as perikymata. Perikymata run in circumferentially horizontal lines across the face of the crown.
- Enamel Lamella : lamellae or cracks in the enamel appear as jagged lines in various regions of the tooth surface.
- Enamel tuft : Enamel tufts are "small, branching defects that are found only at the DEJ, protruding into the enamel towards the enamel surface.
- Enamel spindle : are "short, linear defects, found at the dentinoenamel junction (DEJ) and extend into the enamel.

Struktur gigi

a. Enamel
enamel memiliki ketebalan yang bervariasi :
gigi Anterior(depan) memiliki ketebalan rata-rata : 2 mm
gigi Premolar diukur dari cusp memiliki ketebalan rata-rata : 2,3-2,5 mm
gigi Molar diukur dari cusp memiliki ketebalan rata-rata : 2,5-3,0 mm

b. Dentin
dentin memiliki ketebalan rata-rata : 3-3,5 mm
1. Dentin primer : dentin primer terbentuk sebelum terbentukan akar sempurna hingga 3 tahun setelah gigi tersebut erupsi. Dentin primer membentuk dari bentuk anatomis gigi.
2. Dentin sekunder : dentin sekunder terbentuk setelah pembentukan dari akar gigi sempurna, pada dentin sekunder ini bentuk dari tubuli dentin menjadi lebih asimetri jika dibandingkan pada gigi yang baru terbentuk dentin primer.
3. Dentin reparatif/dentin tersier : dentin tersier terbentuk karena adanya stimulus eksternal, bisa berupa dental karies, atrisi dantrauma. Jadi dentin tersier ini merupakan bentuk respon dari sistem pertahanan tubuh dari stimulus eksternal. Seandainya terdapat suatu injuri yang mengakibatkan sel-sel odontoblas mati maka odontoblast like cells akan membentuk dentin reparatif untuk melindungi jaringan pulpa dari injuri. Dentin reparatif memiliki permeabilitas yang lebih rendah dibandingkan dengan dentin primer maupun sekunder karena untuk mencegah difusi dari agen noxius yang masuk melalui tubuli dentin.

c. Pulpa gigi
pada dasarnya pulpa gigi terbagi menjadi dua area yaitu bagian sentral dan bagian periferal. Bagian sentral terdiri dari pembuluh darah dan saraf, sedangkan pada bagian periferal terdiri dari odontoblastic layer, zona weil ( daerah free cell) dan zona kaya sel(cell rich zone)

Structure of Teeth

a. Enamel Thickness
Anterior tooth-incisal edges : 2.0 mm
Premolar tooth-Cusp : 2.3-2.5 mm
Molar tooth- cusp : 2.5-3.0 mm
b. Dentin
Thickness of dentin 3-3.5 mm
- Primary Dentin : This type of dentin is formed before root completion, gives initial shape of the tooth. It continues to grow till 3 years after tooth eruption. - Secondary Dentin : Secondary dentin is formed after completion of root formation. In this, the direction of tubules is more asymmetrical and complicated as compared to primary dentin. Secondary dentin forms at a slower rate than primary dentin.
- Reparative Dentin/Tertiary Dentin : Tertiary dentin frequently formed as a response to external stimuli such as dental caries, attrition and trauma. If the injury is severe and causes odontoblast cell death, odontoblast like cells synthesize specific reparative dentin just beneath the site of injury to protect pulp tissue. Reparative dentin matrix has decreased permeability, therefore helping in prevention of diffusion of noxious agents from the tubules.
Dentinal Tubules : The dentinal tubules follow a gentle โ€œSโ€-shaped curve in the tooth crown and are straighter in the incisal edges, cusps and root areas. The ends of the tubules are perpendicular to dentinoenamel and dentinocemental junctions. the tubule contains dentinal fluid, a complex mixture of proteins such as albumin, transferrin, tenascin and proteoglycans.
c. Dental Pulp
Basically the pulp is divided into the central and the peripheral region. The central region of both coronal and radicular pulp contains nerves and blood vessels. The peripheral region contains the following zones.
1. Odontoblastic layer
2. Cell free zone of Weil
3. Cell rich zone.

The tooth is made up of four tissues: enamel, dentin, cementum, and pulp. enamel,dentin, and cementum are relatively hard since the contain considerable mineral content, especially calcium.

Enamel
Enamel is the white, protective external surface layer of the anatomic crown. It is highly calcified or mineralized, and is the hardest substance in the body. Its mineral content is 95% calcium hydroxyapatite, The remaining substances include 5% water and enamel matrix. It develops from the enamel organ (ectoderm) and is a product of ameloblasts.
Cementum
Cementum is the dull yellow external layer of the tooth root. The cementum is very thin, especially next to the cervical line. It is composed of 65% calcium hydroxyapatite (mineralized and calcified), 35% organic matter (collagen fibers), and 12% water. Cementum is about as hard as bone but considerably softer than enamel. It develops from the dental sac (mesoderm), and is produced by cells called cementoblasts.
Cementoenamel Juntion
The cementoenamel junction (also called the CEJ) separates the enamel of the crown from the cementum of the anatomic root. This junction is also known as the cervical line, it surrounds the neck or cervix of the tooth.

Dentin
Dentin is the hard yellowish tissue underlying the enamel and cementum. Mature dentin is composed of about 70% calcium hydroxyapatite, 18% organic matter (collagen fibers), and 12% water, making it harder than cementum but softer and less brittle than enamel. Dentin develops from the embryonic dental papilla (mesoderm). The cells that form dentin, called odontoblasts are located at the junction between pulp and dentin.

Dentinoenamel Junction
The dentinoenamel junction is the inner surface of the enamel cap where enamel joins dentin. The cementodentinal or dentinocemental junction is the inner surface of cementum where cementum joins dentin.
Pulp
The pulp cavity has a coronal portion (pulp chamber) and a root portion (pulp canal or root canal). The pulp cavity is surrounded by dentin. Nerves and blood vessels enter the pulp through apical foramina. It develops from the dental papilla (mesoderm).
