Study Notes

Smooth Surface Caries

Introduction

Smooth surface caries refers to the formation of cavities on the smooth, flat surfaces of a tooth, including the sides and circumference of the tooth. Similar to pits and fissures caries, smooth surface caries occurs when bacterial acids dissolve tooth enamel, eventually leading to cavitation. Unlike fissure caries, which typically forms in the biting surfaces of the back teeth, smooth surface caries can occur on any tooth surface, especially in areas difficult to clean through normal brushing or flossing.

Incipient Caries

Incipient caries, also known as "white spots," is the earliest stage of tooth enamel dissolution, preceding cavitation. At this stage, the surface exhibits minimal demineralization and appears chalky white. If left untreated, incipient caries can progress to caries with cavitation, requiring more extensive treatment like fillings or even root canal therapy.

Detecting Smooth Surface Caries

Traditional visual inspections using the International Caries Detection and Assessment System (ICDAS) can struggle to accurately detect smooth surface caries due to the limited depth of information provided. Optical coherence tomography (OCT), specifically 3D SS-OCT, offers a promising solution for detecting early stages of smooth surface caries. This non-invasive imaging technique captures tomographic images of internal tooth structure, providing detailed visualization of enamel lesions, including remineralized and cavitated areas. Studies have shown that 3D SS-OCT can accurately detect smooth surface caries, particularly for deeper lesions without remineralization.

Prevention and Treatment

Preventing smooth surface caries involves maintaining proper oral hygiene, including regular brushing and flossing, and limiting sugar intake. For those susceptible to decay, topical fluoride treatments can help strengthen tooth enamel against demineralization. Additionally, early intervention methods like resin infiltration therapy or microrestorative dentistry can arrest the progression of smooth surface caries before it reaches the advanced stages. These minimally invasive approaches preserve tooth structure and reduce the risk of retreatment, ultimately improving tooth longevity.
