Intraoral radiographs typically consist of periapical and bitewing radiographs, and both have excellent spatial resolution. Caries classification on third molars using PR(s) is flawed by limited and varying accuracy of individual examiners leading to inconsistent decisions and consequently suboptimal care9.

Periapical means surrounding the apex of the root of a tooth ( Fig.1 ); hence it captures the complete crown and root of a tooth with about 2mm beyond the root apex. Caries Risk Assessment and Management Key Points Dental caries is defined as a "biofilm-mediated, sugar-driven, multifactorial, dynamic disease that results in the phasic demineralization and remineralization of dental hard tissues." A thiol-containing agent, like Amifostine, has been used for its radioprotective properties in the prevention of radiation-induced changes by scavenging free radicals.

PMC Radiopaque dyes are used in radiology to enhance X-ray pictures of internal anatomic structures.

Stephan demonstrated that this production of acid after exposure to fermentable carbohydrate resulted in a localized drop in pH within the plaque followed by a subsequent return to the baseline pH over time hence establishing the concept of caries being a cyclic event of demineralization/neutrality/remineralization.

Which Is More Stable Thiophene Or Pyridine. Small occlusal lesions, buccal and lingual pit cavities, are better studied clinically, as radiography plays a small role in the detection of these lesions. Factors that increase somatic exposure to the patient include: Extracted teeth containing amalgam restorations should not be autoclaved because: A radiographic image is produced on a panoramic film by the use of: The embossed dot should face up when mounting. Digital radiographic sensors are an objective and reproducible technique; however, its sensitivity for detection of early and recurrent caries is suboptimal, , with reported sensitivity being as low as 0.30. , Caries detection can be affected by a variety of factors during acquisition or interpretation, such as variation in image capture, detector placement, status of the detector, focus to object distance, kilovolt or milliampere used for capture of the radiograph, ambient lighting for interpretation, or the experience of the clinician. Some examples of radiopaque substances other than barium sulfate, as suggested by the authors, include acetrizoate sodium, iobenzamic acid, iopanoic acid, and iopentol. The objective of this study is to assess the classification accuracy of dental caries on panoramic radiographs using deep-learning algorithms. Solid-state sensors, also known as direct digital sensors, are of 2 types depending on how the image is captured: charge coupled device (CCD) and complementary metal oxide semiconductors.

As these parameters differed between the studies, a direct comparison of these studies would be misleading. Early caries detection is paramount to effective chemotherapeutic, noninvasive management. Lee, H. & Song, J. The proposed method achieved an accuracy of 0.87, a sensitivity of 0.86, a specificity of 0.88 and an AUC of 0.90 for the classification of carious lesions of third molars on PR(s).

Because radiographs are a 2-dimensional representation of a 3-dimensional tooth structure, it is not always possible to determine caries extension to the pulp chamber or pulp horn because of anatomic variations and presence of radiopaque restorations in the crowns.
