Recent research has highlighted the co-occurrence of talon cusp and fusion-the joining of two adjacent tooth germs to form a single large tooth- (Hasiakos et al, 1986;Taloumis & Nishimura, 1989), geminationwhen a single tooth germ attempts to form two teeth- (Cullen & Pangrazio-Culbersh, 1985;Al-Omari et al, 1999;Hattab & Hazza'a, 2001;Cubukcu et al, 2006;Gü ndü z & Açikgõ z, 2006;Agnihotri et al, 2007), and double tooth-the preferred designation when differential diagnosis between fusion and gemination is not possible-in the same dental element of the permanent (Lomçali et al, 1994;Li, 2002;Mayes, 2007;Ekambaram et al, 2008) and deciduous (Mays, 2005;Halcrow & Tayles, 2008;Silva & Subtil, 2009) dentitions.…”

The specimen reported here presents a rare form of dental variant-a permanent, mandibular labial canine talon cusp. This anomaly has not previously been reported in the clinical or archaeological literatures and is currently unique. The affected individual is an adult male from the Early Holocene cemetery of Gobero located in the Sahara Desert in the Republic of Niger. The age of this site (ca. 9500 bp) makes this the first archaeological case of labial talon cusp from Africa and the oldest reported talon cusp of any kind (lingual or labial, maxillary or mandibular, incisor or canine) in the world. Previous case studies, population frequency data, sexual dimorphism patterns and distribution within the dentition are discussed for labial talon cusp. The morphological aetiology of talon cusps is reviewed with respect to this specimen.

To assess management of non-syndromic double tooth affecting permanent maxillary central incisors, we performed a systematic review and also present 2 case reports. We searched MEDLINE via PubMed and the reference lists of included reports. Eligible studies were any type of clinical studies describing the management of non-syndromic double tooth affecting the crown of a permanent maxillary central incisor. We included 68 studies corresponding to 72 relevant case reports. Therapeutic options in descending order of priority were restorative dentistry (35%), hemisection (33%), abstention (17%) or extraction (15%). Orthodontic management resulted in 57% of cases. We report an 11-year-old boy with bilateral fusion of the two maxillary central incisors and a 9-year-old boy with a double left central incisor and a supernumerary lateral right incisor. A multidisciplinary approach is key to management of permanent maxillary central incisors affected by coronary anomalies.

Management of non-syndromic dens evaginatus affecting permanent maxillary central incisors: a systematic review

To assess management of non-syndromic dens evaginatus affecting permanent maxillary central incisor, we performed a systematic review and also present a case report. We searched PubMed via MEDLINE and the reference lists of included reports. Eligible studies were any type of clinical studies describing the management of non-syndromic dens evaginatus affecting the crown of a permanent maxillary central incisor. We included 31 studies corresponding to 34 relevant case reports. Therapeutic options were complete reduction of the talon cusp in a single appointment (56%), periodic and gradual reduction of the cusp (26%), abstention (13%) or extraction (5%). We report an 8-year-old girl with unusual two-talon cusp, labial and lingual, on a right maxillary double central incisor. A multidisciplinary approach is key to management of permanent maxillary central incisors affected by coronary anomalies.
