RESUMEN
Aim: This case report aims to describe the management of a maxillary lateral incisor with a palatogingival groove (PGG) associated with a complex lesion. Background: The PGG is a rare developmental anomaly that involves the lingual surface of the maxillary incisors and extends for varying distances and depths on the root surface. This anomaly is usually inconspicuous and funnel-shaped, which forms a niche where bacterial plaque and calculus can accumulate to levels significant for pathological changes resulting in endodontic and periodontal lesions. These grooves are easily overlooked as etiologic factors, as they are concealed by the periodontal tissues. Case description: This paper describes the successful management of a rare case of maxillary lateral incisor with an accessory root, two canals, and a complex or type III PGG with a endodontic-periodontic lesion using a multidisciplinary approach. Conclusion: Recognizing PGG as the initiator of pathology is critical for the successful treatment and favorable prognosis of the affected tooth. Clinical significance: This case report highlights the importance of three-dimensional (3D) imaging using cone beam computed tomography (CBCT) that can provide accurate and sensitive information to assess and plan the treatment of the teeth with PGG. It also emphasizes that with the development of newer materials and diagnostic tools, clinicians need a detailed understanding of the characteristics, treatment, and prognosis of PGG to successfully manage the condition.

RESUMEN
Aim: This study was designed to compare the clinical efficacy of two esthetic restorative materials, nanoceramic (Magma NT®) and giomer (Beautifil II®), as full coronal restoration in primary maxillary incisors. Materials and methods: A total of 15 patients aged 3-5 years presenting with mutilated primary maxillary incisors due to caries or trauma were selected for the study using randomized simple sampling. A total of 40 maxillary incisors were randomly divided into two equal groups, with 20 teeth in each group. Teeth in group I (GP I) were restored with nanoceramic (Magma NT®) and group II (GP II) with giomer (Beautifil II®). The full coronal restorations were done using strip crowns (3M ESPE). The restorations were evaluated for gross fracture, marginal integrity, and secondary caries according to modified Ryge's criteria [United States Public Health Service (USPHS)] at baseline (immediate postoperative), 3, 6, and 9 months. Parental satisfaction with each type of restoration was also evaluated using the Likert 5-point scale. Results: The data obtained was statistically analyzed using the Chi-squared test, and the level of significance, that is, the p-value, was determined. The Chi-squared test showed no significant changes to all modified USPHS criteria for each material at baseline and 3-month evaluation period. The changes recorded were after a 3-month follow-up between the two materials; nanoceramic (Magma NT®) restoration demonstrated marginally better than giomer (Beautifil II®) in terms of gross fracture and marginal integrity; however, there was no statically significant difference between them (p > 0.05), while giomer (Beautifil II®) was better than nanoceramic in terms of secondary caries (p < 0.05). Parental satisfaction for both entities was comparable in terms of color and durability; however, they were cost-ineffective. Conclusion: Nanoceramic restoration demonstrated better results in terms of gross fracture and marginal integrity, while giomer was better in terms of secondary caries. Clinical significance: Nanoceramics and giomers can serve as an alternative to conventional restorative materials in primary anterior teeth because of their improved qualities.
