“…[ 11 ] In a study by Pinheiro et al ., 70% of PGs were positioned along the distal root surface of the palatal side, followed by 20% in the central, and 10% in the mesial sides. [ 16 ] However, in the present study, 50% of the grooves were present in the mid-palatal surface of the teeth, 33% on distal aspect and 17% on the mesial aspect. Similar findings were reported by Hou and Tsai where 42.5% of PGs were positioned in the midpalatal surface, 30.1% on the distal aspect and 27.4% on the mesial aspect.…”

Aim: This study aims to investigate the prevalence of palatogingival groove (PG) in anterior maxillary teeth in an Indian cohort using cone beam computed tomography (CBCT) scans. Study Design: Retrospective study. Materials and Methods: Analysis of 119 CBCT scans (64 males, 55 females, and mean age 31.6 ± 13.5 years) was performed. The data of 636 anterior maxillary teeth (220 canine, 212 lateral incisor, and 204 central incisor teeth) were studied for PG's presence. Demographic details of patients and characteristics of PG, i.e., location, extension, depth, and type were recorded. Results: Out of the 636 anterior maxillary teeth studied, PGs were detected in 12 (1.88%) teeth (3 [1.47%] central incisors, 9 [4.2%] lateral incisors, and 0 canines). All the teeth were categorized as having either type I (Seven teeth) or type II (Five teeth) radicular groove. Two of the 12 PGs were present in the mesial, six in the mid-palatal, and four were present in the distal portion of the palatal surface of the teeth. Conclusions: The prevalence of PG in maxillary incisors in this Indian cohort is 2.88%. Maxillary lateral incisors are the most affected teeth.

“…Previous research has documented MLIs with RG, noting features such as prominent tubercles, exaggerated cingulums, and pronounced marginal ridges [1,10,15,24,25,29]. However, evaluating these characteristics with consistency posed challenges in our study.…”

Objectives This study aimed to develop and validate a predictive nomogram for diagnosing radicular grooves (RG) in maxillary lateral incisors (MLIs), integrating demographic information, anatomical measurements, and Cone Beam Computed Tomography (CBCT) data to diagnose the RG in MLIs based on the clinical observation before resorting to the CBCT scan. Materials and Methods A retrospective cohort of orthodontic patients from the School and Hospital of Stomatology, Wuhan University, was analyzed, including demographic characteristics, photographic anatomical assessments, and CBCT diagnoses. The cohort was divided into development and validation groups. Univariate and multivariate logistic regression analyses identified significant predictors of RG, which informed the development of a nomogram. This nomogram's performance was validated using receiver operating characteristic analysis. Results The study included 381 patients (64.3% female) and evaluated 760 MLIs, with RG present in 26.25% of MLIs. The nomogram incorporated four significant anatomical predictors of RG presence, demonstrating substantial predictive efficacy with an area under the curve of 0.75 in the development cohort and 0.71 in the validation cohort. Conclusions A nomogram for the diagnosis of RG in MLIs was successfully developed. This tool offers a practical checklist of anatomical predictors to improve the diagnostic process in clinical practice. Clinical Relevance: The developed nomogram provides a novel, evidence-based tool to enhance the detection and treatment planning of MLIs with RG in endodontic and orthodontic therapeutic strategies.

“…PGG might be either unilateral or bilateral ( Everett and Kramer, 1972 , Jeng et al, 1992 , Peikoff et al, 1985 , Peikoff and Trott, 1977 ). Though the exact etiology of this anomaly is unclear, it has been suggested that it could be alterations during tooth development and growth, a mild form of dens invaginatus, or tooth attempts to form another root ( Gu, 2011 , Kim et al, 2017 , Peikoff et al, 1985 , Pinheiro et al, 2020 ). The clinical presentation of the defect is often on the palatal root surface, but, on some occasions, the involvement of the facial aspect has been reported ( Brin and Ben-Bassat, 1989 , Goon et al, 1991 , Kerezoudis et al, 2003 , Kozlovsky et al, 1988 ).…”

“…Smith & Carroll presented a case of maxillary lateral incisor with labial and palatal developmental grooves ( Smith and Carroll, 1990 ). Some studies indicated a tendency for proximal localization of PGG ( Albaricci et al, 2008 , Gu, 2011 , Pinheiro et al, 2020 ).…”
