Palatogingival groove (PGG) is a developmental anomaly affecting mainly the maxillary incisors. The maxillary lateral incisor is narrower mesio-distally than the central incisor. According to a study done by Kagon on staining with Despite an apparently poor prognosis, the tooth was successfully managed by endodontic and surgical periodontal therapy. The developmental groove caused a combined periodontal-endodontic lesion. Hertwig are known by various names namely the palatogingival grooves, radicular lingual grooves, palatal radicular grooves, radicular palatal grooves, distolingual grooves or radicular gingival grooves. Title: Management of various types of palatogingival groove - A case series Abstract: As the name implies, palatogingival groove starts near the cingulum of the tooth and runs towards the cemento enamel junction in an apical direction at various depths and distances. After removing dentin carefully with an ultrasonic device, an orifice was detected by using a size 10 stainless steel K-file (Mani, Tochigi, Japan). A tooth occasionally exhibits a lingual groove that extends from the enamel onto the cemental area of the root. In addition, secondary endodontic infections can be expected based on communication between the pulp canal system and the periodontium through accessory canals [].Evaluation of clinical signs and appropriate diagnostic tests are important to prevent incorrect diagnosis and . A palatogingival groove (PGG) is a predisposing factor for localized periodontal disease and is rare accord-ing to literature reports. Int Endod J 2007;40:808-17. The tooth although still a germ, becomes surrounded by the central incisors, canine and first premolar that are in a It is a developmental anomaly showing alterations in the growth and infolding of inner enamel epithelium and Hertwigs epithelial root sheath creating a groove that passes from cingulum of maxillary incisors apically on to the root. Keywords Additional root, combined periodontal-endodontic lesions, guided tissue regen-eration, multidisciplinary approach, palatogingival groove, papillary reconstruc-tion. Palatoradicular or Palatogingival groove was initially given by Black in the year 1908 described it as a developmental anomaly. Palatogingival grooves are developmental malformations quite notorious for precipitating endodontic - periodontal lesions. There is limited data on the use of cone-beam computed tomography (CBCT) scanning in examining radicular groove (RG). The palatogingival groove is a developmental anomaly , The last treatment option for the presence of the labiogingival groove in a tooth with hopeless prognosis is extraction.,, This case reported here was treated successfully by an interdisciplinary approach which consisted of periodontal, endodontic, and extraction of that tooth. The prevalence rate has been reported to be approximately 2.8 to 8.5%. The successful development of the tooth depends on a complex reciprocal Often the tooth is narrow, conical, or peg-shaped. Introduction: The tooth is a specialized part of the human body, understanding the development of which is enigmatic and still challenging. 9. tooth to severe periodontal diseases3 and has many similarities with dens invaginatus. The development, pathology, and effectiveness of management approaches in cases involving a combined periodontal-endodontic lesion with a palatogingival groove are discussed. Placing amalgam restoration in the groove 5. The prognosis of a tooth with a palatal groove depends mainly on location of the groove, severity of the palatogingival groove. The alteration is an infolding of epithelium in the case of a palatogingival groove, whereas in dens invaginatus, the alteration is an invagination resulting in a circular opening 11. Abstract. Palatogingival groove or Radicular Lingual Groove (RLG) is a developmental anomaly in which an infolding of the inner enamel epithelium and Hertwig's epithelial root sheath create a groove that passes from the cingulum of maxillary incisors apically onto the root. This study aims to investigate the presence of RG in maxillary anterior teeth in a Turkish Population using CBCT scanning and to correlate the findings with the tooth type, and patient's gender. After completion of root canal treatment, flap was raised in 22 region and the unique semilunar bone defect near the apex of the tooth was debrided, bone graft place and flap . In a morphological analysis of these grooves, Ennes Kovacs13 hailed this anomaly "syndesmocorono-radicular tooth." The depth of the groove acts as a haven for micro-organisms. Palatogingival groove is a rare developmental anomaly usually found on the palatal aspect of maxillary anterior teeth.1Region of maxillary anterior teeth are considered to be an area of embryologically importance with major and minor malformations [such as Palato-gingival groove (PGG), Dens-in-dente]. This tooth can be variable. Although it is reported that acceptable periodontal status is of great importance in case selection in intentional replantation, it is suggested in this report that intentional replantation could be chosen instead of immediate extraction if extensive endodontic-periodontal lesions exist in a tooth with palatogingival groove. 3. Salvaging a tooth with a deep palatogingival groove: an endo-perio treatment—a case report. The term was formulated by Lee et al. According to a study done by Lara, 1 macroscopic analysis of teeth revealed that palatogingival groove most commonly occur on the lingual surface of maxillary lateral incisor. Some treatment options were described for such lesions, including primary endodontic treatment and periodontal surgery and extraction with intentional . An interdisciplinary treatment with endodontic and periodontal management was opted. Hattab FN, Yassin OM, al-Nimri KS. he palatogingival groove (PGG) is a developmen-tal malformation that occurs near the cingulum of a tooth and extends along the root to varying lengths. The maxillary lateral incisor (LI) is most commonly (93.8%) affected The palatogingival groove presents a difficult, if not impossible, management problem for the patients and the clinicians. Salvaging a tooth with a deep palatogingival groove: An endo-perio treatment - A case report. The labiogingival notch seen on the central incisors was first described by Brin and Ben-Bassat in 1989 with 6.5% prevalence on at least one central incisor. An interdisciplinary treatment with endodontic and periodontal management was opted. Methods . The hidden trap in the tooth can harbor plaque and bacteria, resulting in periodontal destruction with or without pulpal pathologic change. Dental anomalies include the presence of talon cusp, palatogingival groove, dens invaginatus, conical crown or peg-shaped Dens Invaginatus is an uncommon anomaly of teeth probably resulting from an infolding of the… Palatal groove associated with periodontal bone defects Scaling & root planning Odontoplasty Curettage with odontoplasty Amalgam restoration Extraction GTR with or without bone grafts - Groove extending beyond the middle1/3rd of root apex www.indiandentalacademy.com. [1] and also known as distolingual. A palato-radicular groove (PRG) is a developmental abnormality primarily found in the maxillary lateral incisor.1,2 This irregularity, which is considered a potential communication path between the root canal and the periodontium, clearly decreases the survival rate of the affected tooth.2 As a consequence of this connection, the PRG acts as an expedient route for nutrients to reach bacteria . Which tooth is most susceptible to a lingual palatal groove? They have an incidence rate ranging from 2.8% to 18%. Palatogingival grooves when present may 2 Ballal NV, Jothi V, Bhat KS, et al. 1 Kovacs (1971) called this anomaly 'syndesmocorono-radicular tooth'.

Palatogingival groove is a rare developmental anomaly usually found on the palatal aspect of maxillary anterior teeth.1 Region of maxillary anterior teeth are considered to be an area of embryologically importance with major and minor malformations [such as Palato-gingival groove (PGG), Dens-in-dente]. Diagnosis - proper diagnosis is base for treatment plan, which is made on the basis of clinical examination, along with radiographic examination as well as CBCT scan. Summary Palatogingival grooves are uncommon in maxillary lateral incisors, but when present may contribute to the pathogenesis of periodontal and endodontic lesions. Deep. Palatogingival groove or radicular lingual grooves are developmental malformations that were described by Everett and Kramer (1972) and Robison and Cooley (1988). mobility of the tooth was within physiological limits. 5,6 This case report describes a multidisciplinary approach for the combined management of the endodontic and periodontal problems for successful rehabilitation of the involved tooth. PGG incidence, depth, and length are clinically important because it may cause severe and localized periodontitis; and it may divide the root canal resulting in accessory foramina. The region in which the lateral incisors are located are considered to be an . It runs to various depths of the root surface of the involved tooth. Palatogingival groove in maxillary incisors Another anomaly which occurs in the maxillary incisors (especially in the lateral) is the palatogingival groove (Fig 5).2,11 This defect has been mentioned in the dental litera­ ture by a number of different names, such as distolingual groove,12 devel­ opmental radicular anomaly,13 and A palatal radicular groove (PRG) is a morphological deformity, occurring during tooth development. MAXILLARY FIRST MOLAR Average tooth length 20.8 mm. Most reports have suggested that the palatal groove is single, often extends from the cingulum to the apex and runs parallel to the long axis of tooth. This is MOST likely to be the permanent a. maxillary cuspid b. maxillary third molar c. maxillary central incisor d. maxillary lateral incisor e. mandibular second premolar The second canal was located at the corresponding part of palatogingival groove in the pulpal chamber of the tooth. . Palatogingival groove, also known as palatoradicular gorove, coornoardcua gnroilrgioo duvlts geao, ilro ova rrdecu, i - lolingual groove, is described as a developmental mal-formation that exists on the palatal aspect of the incisor teeth and runs toward the mesial, distal, or midpalatal root regions.3,4 It has a reported incidence ranging from DISCUSSION The predominance of palatogingival groove in maxillary lateral incisor is due to an undesirable position of the lateral incisor during the period of maxillary growth. A radicular lingual groove may also be called as palatogingival groove or radicular developmental anomaly or distolingual groove. Palatogingival groove is a rare developmental anomaly involving the lingual surface of the maxillary incisor and resulting in severe endodontic and periodontal lesions. 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. the abnormalities, palatogingival groove (PGG) is defined as 'a developmental anomaly in a root that, when present, is usually found on the lingual surface of maxillary incisor teeth'.3 The maxillary lateral incisor is most commonly involved because of the embryological hazard of having its tooth germ locked between those of the central Parotid, Stensons. The radicular groove is a developmental groove which is usually found on the palatal or lateral aspects of the maxillary incisor teeth.
