Development of Yorkshire Terrier Dentition

The development of dentition in dogs has been associated with several problems including tooth over-crowding, missing permanent dentition, and persistent deciduous teeth (PDT). Information on different breeds is lacking. This study 61 Yorkshire terriers aimed to determine the (i) average age at exfoliation, (ii) eruption, (iii) PDT incidence, influencing factors such as body weight. ages exfoliation eruption were influenced by weight type. These changes tended occur later ≤ 3 kg versus > 5 kg. Generally, incisors exfoliated first, followed premolars then canines. At a 4.5 kg, middle data range, estimated loss (with 95% confidence intervals) was 21.9 (21.1, 22.9) weeks for incisors, 26.1 (24.9, 27.4) canines, 23.9 (22.9, 24.9) premolar. 22.3 (21.6, 23.0) 23.8 (23.0, 24.6) 24.7 (24.0, 25.5) premolars, 26.4 (25.5, 27.3) molar teeth. However, this sequence disrupted had high incidence PDT. proportion was: 0.86% (0.32, 2.31), canines 15.62% (7.62, 29.37) 3.57% (1.62, 7.66). Canines constituted most frequently retained type, 89.1% compared 12.0% information will enable veterinarians provide personalised advice regarding oral care requirements highlights need regularly monitor breed between two seven months, during active phases development.
