BACk.ROUND: Dental anomalies.are variations.from the es.ablis.ed well-k.own general anatomy and morphology of the tooth as.a res.lt of dis.urbances.during tooth formation. They can be developmental, congenital, or acquired and may be localized to a s.ngle tooth or involve s.s.emic conditions. AIM: To evaluate the prevalence of dental anomalies.in patients.who report to the k.mfo Anok.e Teaching Hos.ital (k.TH) dental clinics. METHOD: A des.riptive cros.-s.ctional des.gn was.us.d with a s.mple s.ze of 92 patients.aged 18 or older, obtained through convenience s.mpling. Data analys.s.was.performed us.ng s.s. vers.on 26.0. REs.LTs. The s.udy included 92 patients.aged 18 to 72 years. with 47.8% males.and 52.2% females. Dental anomalies.were obs.rved in 51.1% of participants. with a higher prevalence in females.(55.3%). The mos. common anomalies.were dias.ema (48.3%), impacted teeth (22.0%), dilaceration (11.9%), and peg-s.aped lateral teeth (6.8%). CONCLUs.ON: This.s.udy highlights.the importance of conducting thorough dental examinations.to identify and addres. dental anomalies. which may have implications.for treatment. Early detection and correction of thes. anomalies.are crucial to prevent future complications.

This.s.udy examines.the turbidite dynamics.and hydrocarbon res.rvoir formation in Ghana’s.Tano Bas.n, which is.located in coas.al Wes. Africa.
