Aims and objective: To assess the prevalence of the developmental dental anomalies like disturbances in size, shape, structure, eruption pattern and number in a group of North Karnataka population and to assess the dental anomalies in patients with head and neck syndrome.Method: A cross-sectional prospective survey was carried out at P.M.N.M Dental College and Hospital, Bagalkot, North Karnataka, India during the academic year, November 2011 to August 2013 to study the prevalence of various developmental dental anomalies of teeth in a population of 3000 patients aged between 10 to 30 years in both genders. Patients were screened clinically for the presence of dental anomalies with appropriate radiographs and dental casts.Result: Of 3000 patients screened, 477 had developmental dental anomalies. Out of these, 254 were males and 223 were females. The most commonly found anomalies were impacted teeth, hypodontia, dental fluorosis, overretained, supernumerary teeth, talon’s cusp with the least being dentinogenesis imperfecta (none).Conclusion: The significance of conducting such a study is, that if the dental anomalies are detected earlier, the consequences (like early pulp involvement in dens-in-dente, malocclusion) can be intervened and treated accordingly. This study hence provides an useful data regarding the prevalence of the most and the least common anomalies in North Karnataka region of India.

“…The accessory cusp has been seen in association with other dental anomalies like supernumary teeth, odontomas, impacted teeth; peg shaped lateral incisors, dens invaginatus (26). In the present study dens invagination (19.35%) was seen more commonly associated with talon cusp followed by impacted canines (19.35%) and partial anodontia (9.67%).…”

“…In the present study dens invagination (19.35%) was seen more commonly associated with talon cusp followed by impacted canines (19.35%) and partial anodontia (9.67%). In hong kong children, supernumary teeth and hypodontia was reported in 8.6% of the cases respectively (26). Concomitant occurance of Dens evagination and invagination is relatively rare (27-30).…”

Aim: To investigate the prevalence of the talon cusps in a sample of Indian dental patients and their distribution among different types of teeth. To determine the presence of other dental anomalies associated with the talon cusps. Method: 2740 out patients (1523 males and 1217 females) attending Oral Medicine department from November 2010 to January 2011 were screened for the presence of talon cusps and were subjected to Intra Oral Peri-apical (IOPA) radiograph to rule out any associated anomalies or peri-apical changes. Results: Talon cusps were detected in 16 out of 2740 patients (person prevalence 0.58%). Thirty one teeth were found to have talon cusp. Maxillary lateral incisors were the most commonly affected teeth (54.8%, 17 teeth), followed by maxillary central incisors and canines (16.12%, 5 teeth).Talon cusp was found in two mandibular central incisors (6.45%) and one each in mandibular second and third molar (3.22% each). Seventeen teeth in 7 patients (54.83%) were found to be associated with anomalies like dens invagination (6 teeth, 19.35%), impacted 13, 23 (6 teeth, 19.35%), partial anodontia (3 teeth, 9.67%), geographic and fissured tongue (2 teeth, 6.45%). Peri-apical granuloma was found in one tooth with talon cusp associated with dens invaginatus. None of the patients were found to be associated with any syndromes. Conclusion: Attention should be paid to the presence of the talon cusp and the associated anomalies. Early diagnosis of the talon cusp can help the clinician in preventing the further complications. Key words:Orthopantomography, atheroma, stroke.

“…In fact while talon cusp can appear alone it is often associated with a long list of dental anomalies, including anodontia (Dayal et al, 1980;Hedge & Kumar, 1999;Dash et al, 2004;Cho et al, 2008); cleft lip and palate Kraus et al, 1966;Schroeder & Green, 1975); dens evaginatus (Davis & Brook, 1986;Cho et al, 2008) dens invaginatus (Hattab et al, 1995;McNamara et al, 1997;McNamara et al, 1998;de Sousa et al, 1999;Lorena et al, 2003;Siraci et al, 2008); impacted teeth (Mader, 1981;Natkin et al, 1983;Lomçali et al, 1994;Al-Omari et al, 1999;Dash et al, 2004); malocclusion (Lomçali et al, 1994;Al-Omari et al, 1999;Lehl, 1999;Hattab & Hazza'a, 2001;Segura-Egea et al, 2003b;Dash et al, 2004;Uslu et al, 2009); megadontia (Goel et al, 1976); microdontia (Hattab et al, 1995); partial anodontia (Lehl, 1999); periodontopathy (de Sousa et al, 1999); root abnormalities (Acs et al, 1992;McNamara et al, 1997;McNamara et al, 1998;Cubukcu et al, 2006); supernumerary teeth (Davis & Brook, 1986;Acs et al, 1992;Zhu et al, 1997;Al-Omari et al, 1999;…”

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.

An Audit of Concomitant Dental Anomalies with Maxillary Talon Cusps in a Group of Children from Hong Kong

Abstract: Children with true talon cusps on the permanent maxillary incisors were more frequently affected by supernumerary teeth in the anterior maxilla. Further studies with a larger sample are needed to confirm a true association.
