CASE STUDY
Monica is a 38-year-old woman who visits the office as a new client for an oral assessment and necessary care.Her health history indicates that she is in good health.Monica reports that she brushes three times per day and flosses every night,but her gums bleed every time she flosses.On completion of the full mouth radiographs,dentist's examination,and diagnosis,the dental hygienist completes the periodontal assessment and dental hygiene care plan.Findings include generalized,papillary and marginal gingival erythema;edema;and increased bleeding on probing at all proximal surfaces,especially teeth 8 and 9.No visible supragingival calculus is observed,but there is flat,easily explorable subgingival calculus present on all proximal surfaces,and there are rings of subgingival calculus in 4-mm pocket depths on the lingual surfaces of the mandibular molars,especially teeth 30 and 31.Furthermore,tooth 14 has facial and lingual recession of 4 mm,circumferential 3-mm pocket depths,a Class I mesial furcation,and cementum that is grainy and soft.
-The dental hygienist completes the instrumentation of the Class I furcation on the mesial aspect of tooth 14 from the lingual approach.What anatomic feature allows for this lingual access?

A) The divergence of the mesial proximal surface toward the lingual aspect allows for this access.
B) The short mesial root trunk and the lingual location of the furcation allow for this access.
C) The proximal and furcal concavities on the mesial root allow for this access.
D) The long root trunk,close root proximity,and distal orientation of the roots allow for this access.
