Morphometric Analysis of Furcation Areas of Multirooted Teeth in a Tunisian Population

Abstract

Aims. The aim of the study was to evaluate the morphological characteristics of furcation of permanent molars in Tunisian population. Materials and Methods. One hundred and four extracted maxillary and mandibular permanent molars were included in this study; comprising 34 maxillary first molars, 18 maxillary second molars, 33 mandibular first molars, and 19 mandibular second molars. For each tooth, the vertical dimension of the root trunk, root length, and interradicular space width were assessed with a micrometer caliber. Different types of root trunk in maxillary and mandibular molars were also analyzed. Statistical analysis was performed using a t-test. Results. Root length decreased from the first to the second molars. This decrease seems to be pronounced at mandibular molars. The most observed root trunk type was type B, with a prevalence of 67.30% in maxillary molars and 51.92% in mandibular molars. The root trunk length increased from the first to the second molars in both maxillary and mandibular. The average width of the interradicular spaces varied on the same tooth and between the teeth. Conclusion. This study provides epidemiological data about molars root length, interradicular space, and root trunk vertical dimension in a Tunisian population that could help clinicians in periodontal and endodontic therapy.

Assessment of Mandibular Molar Root Morphology Using Cone‑Beam Computed Tomography in Periodontitis Patients From Eastern Province: A Cross-Sectional Study

“…First molars of non-periodontitis patients had significantly greater distances to furcation than periodontitis patients. This is in agreement with a previous study [ 21 ] that reported that the root trunk of the first molar was greater than the second and third molars with an average distance of 2.6 mm, making it less prone to periodontal diseases.…”

Furcation Involvement in Periodontal Disease: A Narrative Review

“…The furcation area presents unique situations and challenges that limit the application of routine periodontal therapy. The special anatomy and morphology of the furcation area necessitate an array of special procedures and modified treatment approaches to overcome various confounding factors such as the size and shape of the furcation roof, entrance and the divergence of the roots along with the alveolar housing, and the varied nature and patterns of periodontal destruction [ 16 ]. Furcation plasty (osteoplasty, odontoplasty and root planing) is performed at the furcation level.…”

Morphometric Measurements of Root Anatomic Areas of Maxillary First Premolar Teeth in a Representative Nepalese Population

“…1 The topography of such multirooted tooth prevents appropriate instrumentation access which in turn allows pathogenic microbial flora to persist and renders them inaccessible for periodontal therapy. 2 Effective management of the furcation area necessitates a better understanding of the furcation and root surface anatomy. 2 There is paucity of literature accessing the root surface concavities and morphometric measurements of the furcation area of the maxillary first premolar teeth in Nepalese population.…”

“…2 Effective management of the furcation area necessitates a better understanding of the furcation and root surface anatomy. 2 There is paucity of literature accessing the root surface concavities and morphometric measurements of the furcation area of the maxillary first premolar teeth in Nepalese population. This study aimed to assess the presence of concavities on the root surface as well as morphometric measurement of the root trunk beyond the CEJ were excluded.…”
