Prevalence of developmental anomalies of teeth in a group of North Karnataka population, India

Abstract

<p><strong>Aims and objective:</strong> 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.</p><p><strong>Method:</strong> 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.</p><p><strong>Result:</strong> 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).</p><p><strong>Conclusion:</strong> 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.</p>

Prevalence of Developmental Anomalies of Teeth in a Group of Indian Children A Cross Sectional.

“…Our study observed a prevalence of 0.33% of this condition while Kayal et al 17 and Sener et al have reported a range of 0.03% to 1.5%. The incidence of Dens evaginatus in our study was 0.13% which is similar to the observation by Javali et al 10 The prevalence of dilaceration in our study was 0.03%, while Goya HA et al 18 observed a prevalence of 0.02% and Javali etal reported a prevalence of 1%.…”

“…This is close to 0.93% as observed by Siddaih et al 11 and 0.58% as observed in the study by Prabhu et al 12 The presence of Talon's cusp may cause irritation of the tongue during Section: Dentistry function, compromise esthetics, occlusal interference may lead to cusp fracture, displacement of affected tooth, TMJ pain and traumatic bite. 12 The prevalence of Taurodontism (enlargement of tooth crown at the expense of root) was observed in 0.4% cases, which is close to 0.3% reported by Javali et al 10 and Sener et al 13 Supernumerary teeth or Hyperdontia is a freqent finding in dental practice and in our study it was found in 0.3% cases, which was similar to the findings of Deolia et al and close to 0.5% as observed by Salem G. 14 Most supernumerary tooth are impacted and usualy diagnosed incidentaly on radiographic examination. These may be asymptomatic or may cause tooth displacement and failure of eruption.…”

“…In our study it was 0.1%; which is close to other studies by Javali and Miti. 10 Talon's cusp was the second most commonly found anomaly with a prevalence of 0.5% in our study population. This is close to 0.93% as observed by Siddaih et al 11 and 0.58% as observed in the study by Prabhu et al 12 The presence of Talon's cusp may cause irritation of the tongue during Section: Dentistry function, compromise esthetics, occlusal interference may lead to cusp fracture, displacement of affected tooth, TMJ pain and traumatic bite.…”

Inverted and horizontal impacted third molars in an Early Modern skull from Wrocław, Poland: a case report

“…Impacted tooth is one of the most commonly occurring dental anomalies. Frequency varies depending on the source and study population: 4.5% of dental anomalies in modern population of North Karnataka, India [10], 19.2% in Jatt, Israel [22], 26.2% in Konya, Turkey [28], 56.5% in Bhopal, India [25], 48.3% in Ordu, Turkey [1], 69% in Singapore, China [26]. The most commonly impacted teeth are mandibular and maxillary third molars, followed by maxillary canines [6,22].…”

“…Frequency varies depending on the source and study population (see the text for more details); here we present mean per cent of each type, standard deviation are in round brackets. Sources: [1,10,22,25,26,28].…”
