Mandibular Second Molar Impaction - Literature Review and Case Reports

Abstract

AIM: To assess the incidence of mandibular second molar impaction and the treatment methods for this condition. MATERIALS AND METHODS: A retrospective review of the cases of patients diagnosed with impaction of mandibular molars at the Department of Oral Surgery of the Faculty of Dental Medicine -Plovdiv during the past 11 years was performed.RESULTS: 962 patients with impaction of mandibular molars were operated on in the analyzed period. This diagnosis is relatively rare in second mandibular molars and represents 0.94% of all cases. Most often, diagnosis is based on clinical evidence of missing molars and on panoramic radiographs. In the cases described by us, only surgical treatment was used. CONCLUSION:The treatment of this condition is a challenge which requires an individual approach to each case and an assessment to determine what treatment approach is to be used -surgical or orthodontic.

Prevalence and Distribution of Unerupted/Impacted Teeth Among Individuals 18-25 Years of Age Visiting Outpatient Department of Private Dental College and Hospital in Chennai, India

“…The overall inference of our study among prevalence of unerupted / impacted teeth were higher in males ,(55.74%) predominantly between the age groups of 24 years (18.8%) due to sex-specific mandibular traits with the sexual dimorphism clearly observed with bigger jaw bone in males with higher incidence of Mandibular third molars 41 . This might be due to inadequate space between the distal surface of the second mandibular molar and anterior border of the ascending ramus of the mandible and improper oral hygiene 42 .…”

Three‐dimensional measurement and analysis of mandibular characteristics in subjects with impacted mandibular second molars

“…In other words, the eruption space of the first mandibular molar was smaller in G1 than in G3, possibly contributing to the impaction. Although some studies 22 have suggested that an insufficient eruption gap is the main cause of second molar impaction, the distance measured in this study included the eruption gap of two teeth, which is obviously larger than that of one tooth, and the gap was smaller in G1 than in G3. Therefore, to clarify the relationship between the eruption gap and the impaction of the mandibular second molar, the influence of the mandibular third molar should be excluded.…”
