Turkish Journal of Veterinary & Animal Sciences
A total of 272 specimens of tench (Tinca tinca L., 1758) caught in Lake Mogan (Ankara) were examined for the presence of the plerocercoids of Ligula intestinalis, and growth parameters such as age composition, age-length, age-weight and weight-length relationship and condition factor were calculated seperately for both infected and non-infected fish. The only marked difference was observed in value b between infected (2.745) and non-infected (3.014) fish.

Each tooth group was evaluated according to plaque index, gingival index, sulcus bleeding index, calculus index, periodontal disease index, furcation exposure index, feline odontoclastic resorptive lesions (FORL) and tooth mobility. The prevalence of the disease was evaluated statistically. Upper and lower premolars were affected by periodontal disease at a higher rate than others. Tooth loss was often observed in incisives, premolars and canines concurrently. Sub and/or supragingival calculus accumulations occurred in lower incisive, upper canine and upper premolar teeth, in increasing order. FORL was observed in …
