The aim of this study was to compare the accuracy of a CBCT (NewTom 9000), a limited CBCT (LCBCT) (Accu-i-Tomo) and a storage phosphor plate (SPP) (Digora Optime) imaging systems in assessing the depths of mechanically created defects with different shapes and depths on the proximal surfaces
of extracted teeth.
Similar constructions are seen in monoplastidic meiosis of mosses and hornworts as microtubules emanate from plastids as well as the proximal surfaces
The Pearson Correlation Coefficient between measurements of buccal/ palatal and proximal surfaces
was 0.35 and 0.05 in the groups treated with alcohol, in sites with or without ligature, respectively.
(1,6) The absence of biological spacing between the proximal surfaces
of the primary molars is associated with higher caries prevalence.
Two hundred sixteen proximal surfaces
were evaluated for the presence and severity of carious lesions on bitewing-simulated projections using D-speed film/circular, E-speed film/rectangular, and E-speed film/circular collimation.
In 2003, there were fewer caries-free adolescents and also more individuals with initial and manifest carious lesions and restorations on proximal surfaces
, among individuals in the F cohort compared with individuals in the S cohort (Figure 1).
The most common sites for caries to occur are pits and fissure and proximal surfaces
.3 These areas are more difficult to clean and thus more prone to caries.
The curved proximal surfaces
of the contacting teeth roll away from the contact area at all points, occlusally or incisally, labially or buccally and lingually and cervically, and the embrasures and interproximal spaces are continuous, as they surrounds the area of contact.
The two largest brushes are for spaces where a tooth or several teeth have been lost, leaving the adjacent proximal surfaces
difficult to clean with a traditional brush.
* Proximal surfaces
were affected more in first than in second molars,
(14) Toothbrush studies report more plaque removal from buccal and lingual surfaces than proximal surfaces
, and from more anterior surfaces than posterior surfaces.
The proximal contact or contact area refers to the surface where the proximal surfaces
of neighboring teeth come in contact.6 Failure to obtain ideal contact usually results in food impaction into the interproxi- mal space, resulting in trauma to periodontium, in- flammation, pain and bone loss.7 Different contact forming instruments and matrix systems are cur- rently being used to ideally reproduce contact point for proximal composite restorations.
