What is Palatoradicular groove? Endod Dent Traumatol.16 (3) 132-7. This anomaly is also known as "the palatal groove", "the palatogingival groove" or "the radicular lingual groove". e radicular groove is a developmental groove which is usually found on the palatal or lateral aspects of the maxillary incisor teeth. The tooth of the first case was extracted because of severe bone destruction. It is most commonly seen in the maxillary lateral incisors and less frequently in the central incisors. The palate-gingival grooves are an anatomical anomaly in maxillary incisors, which might result in local periodontal pocket formation, bone loss and sometimes pulpal necrosis. Complex facial radicular population: A micro-computed tomographic study. *lateral incisors may have a palatal groove on the cingulum that extends into the cervical 1/3 of the lingual surface. 1: Photograph demonstrating the sinus Fig. 1 The presence of a palatal pit or groove (Figs.

Fig 2 (right) A deep periodontal bone defect is present in ths mesial aspect of the lateral incisor mesial aspect of the lateral incisor and the distal aspect of the central incisor (Fig 2). Some treatment options were described for such lesions, including primary endodontic treatment and periodontal surgery and extraction with intentional . 3-Large developmental groove on the palatal aspect extending to the root (palatogingival groove, palatoradicular groove ). The radicular palatal groove - a therapeutic modality The radicular palatal groove - a therapeutic modality Friedman, Shimon; Goultschin, Josef 1988-12-01 00:00:00 Abstract A radicular palatal groove may be present in about 8.5% of the population, mainly in maxillary lateral incisors. Often this condition predisposes periodontal defects and severe bone destruction, which have been considered untreatable, and extraction has been recommended as a solution. The existence of palatal grooves is rare, with a prevalence ranging from 2.8%-8.5% [ 2 ]. All lateral incisors were carefully examined for the presence, extension of palato gingival and caries development in groove. Medicine Journal of Periodontology & Implant Dentistry The palate-gingival grooves are an anatomical anomaly in maxillary incisors, which might result in local periodontal pocket formation, bone loss and sometimes pulpal necrosis. This case report provides valuable information about the diagnosis and treatment plan of palatogingival grooves with Cone-beam computed tomography (CBCT) scan. It is usually located on the palatal aspect of maxillary incisors and frequently associated with periodontal or endodontic-periodontal lesions. . lateral excursion.3,14 Conclusion The longevity and replacement of a maxillary 2-unit cantilever FPD is presented in this clinical report. The palatogingival groove is a rare developmental anomaly with 2.8% - 8.5% prevalence, located at the palatal aspect of lateral incisor due to the arrest trail of an additional root and unclear etiology.

Both malformed lateral incisors exhibited ex-tra cusp-like projections in the palatal region, forming a 'T-shaped' incisal edge of the crown. According to their localization they are differentiated as distal, mesial and central patterns, with the distal position dominating, as it occurs . Root canal obturation was completed with gutta-percha 17,18 Salama and Nadkarni The dens in dente are also found more frequently in this area than anywhere else in the dentition. A talon cusp and two radicular grooves between the cusp and the palatal surface of the tooth were found on the lateral incisor on the mesial side. USA). Maxillary Lateral Incisor: Proximal View. 7,8 Kramer and Everett reported that the incidence of a palato-gingival groove extending to the apex in maxillary lateral incisors is 0.5%. pocket, and there was pus discharge on palpation from This article illustrates a case of interdisciplinary the palatal gingival sulcus of 12 together with the pres- management of a maxillary right lateral incisor ana- ence of a palatoradicular groove extending apically tomically complicated with palatogingival groove and beyond the cervical line. Background: Teeth with a palatal groove often present with severe localized periodontal attachment loss including pocket formation and alveolar bone loss. A radicular groove develops with the alteration in the growth of the inner enamel epithelium and Hertwig's epithelial root sheath and involves primarily the maxillary lateral incisors. 1c). 2. 3: Periapical radiograph showing periradicular radiolucency associated with maxillary right lateral incisor one vertically oriented radiolucent line is also evident within tooth lateral incisors. There is limited data on the use of cone-beam computed tomography (CBCT) scanning in examining radicular groove (RG). The hidden trap in the tooth can harbor plaque and bacteria, resulting in periodontal destruction with or without pulpal pathologic change. The palatal pit or groove always is the entrance of the invagination, which varies in size or depth.50,51 Sometimes, the formation of a palatal groove results from a cingulum bifurcation. Srinivas**; Arora Pooja***; Jithendra K.D. This report describes clinical cases of a palato-gingival groove on a maxillary lateral incisor with associated localized periodontal disease and pulp necrosis. In the present case, there was a groove on the palatal side of a maxillary lateral incisor with vital pulp. The tooth exhibited pulpal vitality. Unlike dens invaginatus, however, the infolding that occurs in the palatal groove is usually less extensive and creates an external defect that is situated . palatogingival groove is a morphological aberration known to frequently affect maxillary incisor teeth with a rate of affliction seen to be higher in lateral incisors (4.4-5.6%) compared to central incisors (0.28-3.4%).1,10present as a structural variation, it is clinically significant because it serves as an ideal harbor for plaque and … A palatal radicular groove is an unusual developmental deformity of the tooth, with the groove usually starting near the cingulum of the incisor, running apically, and terminating at various lengths along the root [ 1 ]. The etiopathogenesis of palatogingival groove has not been fully elucidated. Palatal radicular grooves have been the subject of many reports since Lee et al noted their presence, named them officially, and discussed their potential clinical significance in 1968.

After periodontal probing, a palatal groove was detected which started at the cingulum and travelled apically and laterally, associated with a pocket sized 8 mm in depth (figure 1). The aim of the present case report was to describe the regenerative surgical treatment of periodontal and bone lesions associated with the subgingival extension of a palatal groove affecting a maxillary lateral incisor. Focal loss of periodontal attachment associated with these grooves, some of which may extend to the apical third of the root, could result in a hopeless prognosis for tooth retention. 2: Palatogingival groove in maxillary right lateral incisor Fig. [6] A great number of malformations occur in this region, namely, globulo-maxillary cysts,[25] and cleft palate,[26] as well as missing,[27] supernumer-ary,[28] dens invaginatus,[29] or peg-shaped lateral incisors. The patient's medical history was non-contributo-ry. Attam K, Tiwary R, Talwar S, Lamba AK. The prevalence of palato gingival groove was 10%.

In article CrossRef PubMed [20] Everett FG, Kramer GM. Palatal Radicular Groove. Palatogingival groove (PGG) is an anomaly in the maxillary anterior teeth, often accompanied by the area of bony destruction adjacent to the teeth with no carious or traumatic history. It was unilateral in 24 (89%) and bilateral in 3 (11%). let's take a look at the mandibular lateral incisors. As the MNP fuse with each other, they form the premaxilla, including the medial portion of the upper lip (philtrum) and the primary palate.11 Exact origin of the maxillary lateral incisor relative to the MNP/MP fusion area and the location of the premaxillary/maxillary suture in the human is an open question. Palatal grooves or DI can present difficult diagnostic and treatment challenges. In the present case, there was a groove on the palatal side of a maxillary lateral incisor with vital pulp. Jun 1972.

Figure 6: Palatoradiucular groove after debridement. The prevalence of palato gingival groove was 10%. The radicular groove is a developmental anomaly that usually starts near the cingulum of a tooth and extends along the root in varying lengths. All lateral incisors were carefully examined for the presence, extension of palato gingival and caries development in groove. Fig. Clinical examination and radiographs revealed poorly obturated maxillary left lateral incisor with an untreated patent second root and a palatogingival groove. 7. It is a linear depression that sometimes reaches the apex [ 1 ]. Results: LCVG was found in 27 adolescents (4.5%). The length of service of the prosthesis was 53 years. Lingual view of maxillary lateral incisor may have a developmental groove extending onto the root "Linguogingival fissure" When groove extends on to root it may be predisposing factor in local periodontal disease. CRIS Current Research Information System. Probing of the sulcus around the tooth did not reveal a peridontal pocket. A 20-year old female presented with failing endodontics.

The deformity was classified as mild, moderate, or severe according to predetermined criteria. There was a groove in the center of the crown extending from the buccal to the palatal region. Palato-radicular grooves in maxillary lateral incisors have been implicated as an initiating factor in localized gingivitis and periodontitis. After an examination of 3168 extracted incisors, Kogon9 reported the prevalence to be 3.4% in central incisors and 5.6% in lateral incisors. There was no history which have also been termed radicular lingual grooves, of trauma and / or discoloration of the tooth. These grooves typically begin in the central fossa. groove is a rare developmental anomaly with prevalence rate of 2.8-8.5%, mostly present on the lingual surface of the maxillary lateral incisor.

Storrer CM, Sanchez PL, Romito GA, Pustiglioni FE. The palatal groove is defined as "a developmental groove in root, that when present is usually found on the palatal aspect of the maxillary incisor teeth." Palato-radicular groove is a rare developmental anomaly with prevalence rate of 2.8-8.5%, mostly present on the lingual surface of the maxillary lateral incisor. Patients with missing or crowned lateral incisors were excluded from the study. A palatocervical groove is a more common finding in maxillary lateral incisors than in central incisors. 7 5,6 The incidence of this condition ranges from 1.9% to 8.5%. Arch Oral groove in a maxillary lateral incisor. Fig 1 (above) A maxillary lateral incisor with a palatal groove ex-hibits an 8-mm probing depth.
