Ectopic teeth have been rarely described in non-dental and non-oral localizations. Ectopic tooth eruption in maxillary sinus usually runs across incidentally during routine radiological or clinical evaluation because it is generally asymptomatic. If it occurs symptomaticaly; the findings like purulent rhinorrhoea, facial pain, headache, swelling, epistaxis and epiphora can be seen. It is often ...

Caldwell-Luc procedure, canine impaction, dentigerous cyst, ectopic tooth. Abstract A case of a large dentigerous cyst associated with canine tooth in the maxillary antrum is presented. This case is of interest because of its extensiveness and the presence of an ectopic tooth in the roof of the maxillary sinus. Theoretical aspects of canine impaction and cyst formation are reviewed. The managem...

Dental implants can be accidentally introduced into the maxillary sinus both during and after surgical installation. Both situations are uncommon and usually induce sinusitis or others important complications.1 The aim of the present study was to report a rare clinical case of late displacement of a dental implant into the maxillary sinus, in which a Caldwell-Luc (CL) approach was performed, fo...

The data show that an increase in government provided old-age pensions is strongly correlated with a reduction in fertility. What type of model is consistent with this finding? We explore this question using two models of fertility: one by Barro and Becker (1989), and one inspired by Caldwell (1978, 1982) and developed by Boldrin and Jones (2002). In Barro and Becker’s model parents have childr...
