Assessment of non-carious root surface defects in areas of gingival recession: A descriptive study

Abstract

BackgroundThe purpose of this descriptive study was to observe the distribution of four different classes of non-carious cervical root surface discrepancies in teeth with gingival recession. Additionally to explore the different treatment modalities in the literature for each of these defects.Material and MethodsA total of 150 subjects with at least one labial gingival recession were included in the study. 1400 teeth were evaluated using 2.5 X magnification loupes and UNC -15 probe for the presence of the cemento-enamel junction and step like defects according to Pini-Prato’s classification: A-, identifiable CEJ without defect; A+, identifiable CEJ with defect; B-, unidentifiable CEJ without defect, B+, unidentifiable CEJ with defect. Further a comprehensive electronic and hand search of pubmed indexed journals was performed to identify appropriate treatment modalities for these defects and their predictability following restorative/surgical or combination of both.ResultsA total of 1400 teeth with exposed root surfaces were examined (793 Maxillary; 607 mandibular). 499 teeth were A-, 405 were A+, 322 were B+ and 174 were B-. The distribution of these defects in different teeth was: 36% premolars, 32% molars, 21% incisors and 11% canines, collectively 68% in the aesthetic zone.ConclusionsMajority of these lesions are in the maxillary aesthetic zone. Hence the presence of the CEJ and the defect must be taken into account while managing these defects surgically. Key words:Cervical abrasion, gingival recession, magnification loupes, root coverage, step defects.

Prevalence of gingival recession and study of associated related factors in young UK adults

“…Non carious cervical lesions (NCCLs) at the cervical margin of the tooth have also been linked to gingival recession, and in some cases, dentine hypersensitivity [30]. In a recent study [31] gingival recession was associated with the presence of NCCLs, 52% of teeth having an exposed CEJ demonstrating a step consistent with an NCCL. NCCLs generally occur on buccal or labial surfaces of teeth along the gingival margin, with erosive toothwear and tooth brushing in an acid environment suggested as aetiological agents for these lesions [32].…”

Current state about root coverage using soft-tissue substitutes in the presence of noncarious cervical lesions: A literature review

“…[ 8 ] Approximately half of the cases of GR are associated with NCCLs, resulting in combined defects (CDs),[ 9 ] and the majority of the latter are in the maxillary esthetic zone. [ 10 ]…”

Efficacy of fluoride varnish containing xylitol coated calcium phosphate or potassium nitrate gel versus conventional fluoride varnish in management of hypersensitivity of exposed root surfaces in adult patients: A randomized clinical trial

“…Some iatrogenic factors may increase gingival recession such as periodontal therapy or orthodontic tooth movement. [1,2] Dentinal hypersensitivity may be presented by the patients differently ranging from a minor inconvenience to disturbing pain affecting their life quality, also the treatment modalities are considered a challenge to dental practitioners with low success rates in relieving the pain which is characterized by being localized or generalized ranging from a single tooth to many teeth surfaces and pain usually disappears after the removal of the stimulus. [3] Management of dentin hypersensitivity could be accomplished through two main strategies either dentinal tubule occlusion or reducing nerve excitability [4].…”
