“…Later in 2004 Farman [4] stated that impacted teeth are those teeth that are prevented from eruption due to a physical barrier within the path of eruption. Generally, third molars erupt between the ages of 18 and 21 years [5,6] and their eruption time varies with races [5][6][7][8]. For instance, mandibular third molars may erupt at 14 years of age in Nigerians [7] and may erupt even at an age of 26 years in European population [8].…”

Context: To date, there are very few studies regarding the eruption status of third molars in South Indian population. This study aims to analyse the eruption status of third molars and also the reasons behind their impactions. Aim:To study the prevalence of eruption status of third molars in South Indian population. Materials and methods:Status of third molars was evaluated radio graphically for 150 subjects (75 males and 75 females) and the impaction status, eruption status and congenital absence of third molars were recorded. Statistical analysis used:The results were analysed using chi-square test. Results:Out of the expected number of molars in 150 patients i.e. 600, only 317 molars (52.8%) were completely erupted and 250(41.6%) failed to erupt completely and were impacted and 33(5.5%) molars were congenitally absent. Conclusion:Third molar impactions have a mandibular predisposition. Third molar impaction showed a predilection towards females than males.Agenesis of third molars was more common in females than in males and was more common on the right side. The most common pattern of impaction was Mesioangular followed by vertical which is more common on the left side, horizontal which is common on the right side. The most commonly impacted teeth were 18 and 48.

ObjectivesThe purpose of present article was to review impacted mandibular third molar aetiology, clinical anatomy, radiologic examination, surgical treatment and possible complications, as well as to create new mandibular third molar impaction and extraction difficulty degree classification based on anatomical and radiologic findings and literature review results.Material and MethodsLiterature was selected through a search of PubMed, Embase and Cochrane electronic databases. The keywords used for search were mandibular third molar, impacted mandibular third molar, inferior alveolar nerve injury third molar, lingual nerve injury third molar. The search was restricted to English language articles, published from 1976 to April 2013. Additionally, a manual search in the major anatomy and oral surgery journals and books was performed. The publications there selected by including clinical and human anatomy studies.ResultsIn total 75 literature sources were obtained and reviewed. Impacted mandibular third molar aetiology, clinical anatomy, radiographic examination, surgical extraction of and possible complications, classifications and risk factors were discussed. New mandibular third molar impaction and extraction difficulty degree classification based on anatomical and radiologic findings and literature review results was proposed.ConclusionsThe classification proposed here based on anatomical and radiological impacted mandibular third molar features is promising to be a helpful tool for impacted tooth assessment as well as for planning for surgical operation. Further clinical studies should be conducted for new classification validation and reliability evaluation.

“…Most parents are anxious about the timing of eruption which is considered as an important milestone during a child's development (1). Paediatricians' opinion regarding the timing of eruption of primary teeth is often sought by the parents.…”

Objective: To determine the chronological eruption parameters of primary teeth in Indian children. Study Design: A longitudinal study consisting of 135 healthy children (74 boys and 61 girls) attending three child health centres in the city of Hyderabad, India were randomly selected and followed from the emergence of the first to the last tooth. Ages and order of tooth eruption were studied for both genders. Results: Boys showed tendency towards earlier eruption for all teeth except maxillary second molar and maxillary/mandibular first molars which erupted earlier in girls. Comparison between maxillary and mandibular showed a tendency to earlier mandibular eruption of central incisors, lateral incisors and second molars in both genders. Conclusions: Within the limitations of this study, a baseline data and chronological table for eruption of primary teeth among Indian children has been established. Indian children experienced delayed eruption of primary teeth when compared to their counterparts in other populations.
