Summary
Molar root fusion is linked to localized periodontitis, with higher prevalence in females. This condition affects specific molars, showing significant differences between healthy and diseased sites.
Area of Science:
- Dentistry
- Periodontology
- Oral Radiology
Background:
- Molar root fusion is a developmental anomaly.
- Its association with periodontal disease requires further investigation.
Purpose of the Study:
- To investigate the relationship between molar root fusion and localized periodontitis.
- To determine the prevalence and distribution of molar root fusions.
Main Methods:
- Examined 143 individuals (1,109 molars) aged 23-68 years.
- Diagnosed molar root fusions using periapical radiographs and clinical probing.
- Measured periodontal parameters: probing depth (PD), clinical attachment loss (CAL), gingival index (GI), and plaque index (PLI).
Main Results:
- Prevalence of molar root fusions was 15.2% in males and 32.2% in females.
- Maxillary second molars showed the highest prevalence (51.8%), followed by mandibular second molars (32.3%).
- Statistically significant differences in PLI, GI, PD, and CAL were observed between healthy and diseased sites with molar root fusions.
Conclusions:
- Molar root fusion is significantly associated with localized periodontitis.
- Females exhibit a higher prevalence of molar root fusion.
- Root fusion impacts periodontal health, necessitating careful clinical evaluation.
