This paper presents a case report of a nineteen year old male patient who reported to the dental clinic with a chief complaint of pain in his upper left back tooth. The patient was in good health and his prenatal and post natal history was uneventful. The child was born to non consanguineous parents. His medical history was non-relevant. There was no history of extractions or any oral surgical procedures. The dentition of the parents and sibling were normal. Details of family history revealed absence of any sign, symptom or disease in his cousins/relatives.A complete medical examination was done to rule out any systemic abnormality. The general and physical examination of hair, nails, sweat glands, eyes, and cheeks showed no positive findings. No significant abnormality was revealed in extra oral examination. Upon intra oral examination, the entire mucosa appeared apparently normal.
The hard tissue examination revealed certain findings. The maxillary arch showed the deciduous molars are retained on both the sides and the upper left third molar is visible only as a slight single cusp. On clinical examination, retained deciduous maxillary left first molar (64) and right second molar (55) with dentinal caries were found. There was no evidence of mobility with retained deciduous molars. The other teeth present in the oral cavity were of normal size, shape and color. The clinical photograph of mandibular arch showed retained deciduous molars only on the left side whereas on right side there was normal eruption of the premolars.

Dry powder inhalers (DPIs) are commonly employed in the management of asthma and other diseases with airway obstruction. A causal relationship of DPI use and occurrence of dental caries has been speculated. The present case-control study was therefore designed to examine the potential link between dental caries and specific use of dry powder inhalers in patients with bronchial asthma.
