Expectedness: device breakage: unexpected us/ca. Causality: latency - compatible, recognized association - no, analysis - this case reported a break at the hub of the suspected device henry schein standard needles 30ga short, requiring dentist intervention to remove the broken part. The possible causes of broken needle may result from: involuntary sudden movement of the patient, especially because it is a paediatric patient; involuntary movement or mishandling of the dentist during injection; the use of a needle size inappropriate to the type of procedure; unexpected contact with hard tissues (e. G. Bone); excessive bending of the needle before use or during use by the dentist; excessive pressure leading to a break of the needle; quality defect of the needles; the method used for the anaesthesia and the dental procedure are not specified.

Therefore, due to the lack of data, this case is considered as not assessable. Dechallenge - na, rechallenge - na, concluded causality who: not assessable.
