Pak Oral Dental J Jan ;34(4):756-60.

The objective of current study was to determine the frequency and risk factors of dental erosion and its grades at presentation and to find frequency of common risk factors i.e. acid regurgitation, vomiting, carbonated drinks and occupational acidic environment among patients presenting with highly suspected clinical features This Cross-sectional descriptive study with sample size of 264 was conducted at Prosthodontic Department, Sardar Begum Dental College, University Town, Peshawar from 17th May 2012 to 17th December 2012. Patients with age 18 years or above of both gender presenting with highly suspected clinical features were subjected to detailed oral and dental examination. Nature of tooth surface loss (attrition, abrasion, erosion) was recorded in specially prepared proforma. Patients having dental erosion were graded according to Eccles and Jenkins Index and they were carefully scrutinized for risk factors. One tooth with highest grade of erosion was considered for assessment. Teeth with caries, fractured, with restorations and congenital anomalies were not considered for grading and were excluded. Results showed mean age of the patients was 38.34 years, SD ±10.968. The tooth wear due to dental erosion among study subjects was recorded 73.5% and due to abrasion and attrition was 26.5%. The most common risk factor was carbonated drinks which was 19.7%. Other risk factors were vomiting (13.3%), occupational erosion (7.6%), acid regurgitation (17%), carbonated drinks+acid regurgitation (7.6%), carbonated drinks+occupational erosion (8.3%). The grades of erosion according to Eccles and Jenkins Index was 29.2% in grade- 1 and 44.3% erosion was in grade-2 and no patient was observed with grade-3. Majority of patients were in age group 42-49 (25.4%). Patients in age group 18-25 were 13.3%. It was concluded that risk factors i.e. carbonated drinks, vomiting, acid regurgitation, and occupational hazards may lead to dental erosion.
