Summary
Caries is the primary reason for tooth extractions in Hong Kong, even in older adults. This study highlights the ongoing impact of dental caries despite water fluoridation.
Area of Science:
- Dentistry
- Public Health
Background:
- Tooth extractions are a common dental procedure.
- Understanding the reasons for extraction is crucial for public health initiatives and preventive strategies.
Purpose of the Study:
- To investigate the primary reasons for tooth extractions among adults in Hong Kong.
- To analyze extraction patterns by age and tooth type.
Main Methods:
- A survey was distributed to 270 dentists from the Hong Kong Dental Association.
- Data on 8516 extractions for 6331 patients (aged 16+) were collected over 5-6 weeks, excluding third molars.
Main Results:
- Caries accounted for 60% of extractions, followed by periodontal disease (28%).
- Periodontal disease was more frequent in older adults (40+), but did not surpass caries even in those 60+.
- First molars were the most frequently extracted teeth, with mandibular incisors most commonly extracted due to periodontal disease.
Conclusions:
- Caries remains the leading cause of tooth extraction across all age groups in Hong Kong, despite long-term water fluoridation.
- Preventive dental care focusing on caries reduction is essential.
