Extremes in second molar eruption in two oriental patients
British Dental Journal
|June 10, 1989
Summary
This study presents two unusual cases of maxillary second molar eruption in Chinese boys, one at 8 years and another at 17 years. These extreme eruption timings highlight variability in dental development.
Area of Science:
- Dentistry
- Human Biology
- Pediatric Dentistry
Background:
- Maxillary second molar eruption typically occurs within a specific age range.
- Understanding variations in eruption timing is crucial for diagnosing developmental anomalies.
Observation:
- Two cases of maxillary second molar eruption are detailed.
- The patients were Chinese boys aged 8 years 2 months and 17 years 4 months.
Findings:
- The observed eruption times represent significant extremes for maxillary second molars.
- Such wide variation in eruption timing has not been previously reported in scientific literature.
Implications:
- These cases suggest a broader spectrum of normal eruption variability than previously documented.
- Further research is needed to explore the factors influencing extreme eruption timings in permanent teeth.
