The proposed grading systems for both oral and ocular involvement in MMP are easy to use, and show good agreement between observers. The proposed ocular system correlates well with a currently used system, and overcomes some of the difficulties encountered with existing systems. For the individual patient, changes greater than 1.5 mm (vertical) and 3 mm (horizontal) are significant. This may increase our ability to detect change or disease progression. Although the risk of ocular involvement in patients with only oral involvement has been demonstrated, the severity of oral and ocular disease are not well-correlated, due in part to an absence of an ocular disease activity score.

The cementoblastoma is a rare, benign odontogenic tumour. It is generally asymptomatic and usually occurs in young adults. It is more common in males. It is most often associated with mandibular molar teeth and has a characteristic radiographic appearance. This case report is of a young male patient who presented with a cemento blastoma associated with a maxillary second molar. The initial presentation was to his dentist with pain, which was assumed to be of dental origin. This case highlights the importance of adequate radiographic investigation and appropriate interpretation in forming a diagnosis. It also serves as a reminder that rare odontogenic tumours may present initially in primary care and it is essential that all practitioners are aware of them.
