Root Surface Area of the Mandibular Cuspid and Bicuspids

Abstract

This study found the total root surface area to be greater than that in most previous studies. Increasing attachment loss is related to decreasing root surface area; however, this relationship is not directly proportional. No statistical difference was found between measuring 4 surfaces versus only 2 surfaces.

Calculus Removal With Diamond‐Coated Ultrasonic Inserts In Vitro

“…On average, DIs (29.7 seconds) took the shortest time compared to HIs (49.8 seconds) and PIs (91.9 seconds), for a 5 × 5‐mm relatively flat demarcated area with moderate to heavy calculus. It was estimated that for the mandibular cuspid and first and second bicuspids, the area from the cemento‐enamel junction (CEJ) to 4 mm apically corresponds, on average, to 94, 92, and 68 mm 2 , respectively 29 . The calculus areas defined in our study corresponded to a single root surface and measured an average of 5 × 5 mm for a surface of ∼25 mm 2 .…”

Estimation of the remaining periodontal ligament from attachment‐level measurements

“…The relationship between attachment level and remaining area of periodontal attachment has been studied using specific tooth types (Dunlap & Gher 1985, Gher & Dunlap 1985, Matsuura et al 1989, Mowry et al 2002), or a representative of each tooth type (Despeignes 1979). A recent study reported formulae for estimating the surface area of the dentogingival epithelium (i.e.…”

Decreased Amount of Supporting Alveolar Bone at Single-Rooted Premolars Is Under Estimated by 2D Examinations

“…1). Previous studies have reported various total RSAs for premolars6111213141516. A wide range of tooth size, root anatomy, and diverse methods and applications may elucidate this dissimilarity.…”

“…The roots of human teeth present a tapered but also complex anatomic morphology (i.e., the radius at a cross-section varies when measured from the center of the root to the facial, lingual, mesial, or distal root surface at different corono-apical levels). Scholars have investigated the quantitative relationship between the amount of residual periodontal attachment and total root surface area of one tooth with regard to periodontium loss5678. However, the differentiated information regarding the percentage of maximal bone support evaluated using a 2D view compared with that using a 3D image remains limited.…”
