Assessment of lung function in partially edentulous patients using spirometry: A cross-sectional study

Area of Science:

• Oral health and respiratory medicine.
• Cross-sectional study in prosthodontics.

Background:

• Partially edentulous (PED) condition, defined as missing more than 3 posterior teeth, may impact systemic health.
• Lung function is crucial for overall health and disease prevention.

Purpose of the Study:

• To evaluate the effect of the partially edentulous condition on lung function.
• To compare airflow rates between dentulous and PED subjects using spirometry.

Main Methods:

• Cross-sectional study involving 28 dentulous and 28 PED participants (ages 25-50).
• Spirometric evaluation including forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and peak expiratory flow rate (PEFR).
• Independent t-test used for statistical analysis.

Main Results:

• PED participants showed significantly lower FVC, FEV1 (P=0.0005), and PEFR (P=0.032) compared to dentulous individuals.
• Male participants generally exhibited higher airflow rates than females.
• Statistical significance was observed in all measured spirometric parameters.

Conclusions:

• Individuals with a partially edentulous condition demonstrate diminished lung airflow rates (FVC, FEV1, PEFR).
• Lower airflow rates in PED individuals may suggest an increased risk or tendency to develop chronic obstructive pulmonary disease (COPD).
• Further research is warranted to explore the causal link between oral health status and respiratory disease.
