The Epworth Sleepiness Scale (ESS) is a self-administered questionnaire with 8 questions. It provides a measure of your general level of daytime sleepiness, or your average sleep propensity in daily life. It has become the world standard method for making this assessment.

The total ESS score provides an estimate of a general characteristic of you – namely, your average level of sleepiness in daily life. This can be influenced by many factors, and the ESS does not distinguish which factor(s) have caused any particular level of daytime sleepiness. It is not a diagnostic tool in itself, but is a very useful tool for measuring one important aspect of your sleep-wake health status.

Pleasantly surprised by post-surgery follow up

It was a pleasure to have straight forward information provided and constant follow up after my surgery. I was pleasantly surprised to receive a call from Dr. Steven Koos late at night to make sure I was having a healthy recovery. And the cherry on top of the ice cream was how updated the office was. State of the art equipment that I had no doubt I was in good hands.

Great place and great staff.

Great place and great staff. I was well informed about the entire procedure and the follow up process. I also felt very at ease knowing the doctor called me later in the day and him providing me his number in case anything happens.

They took great care of me.

I had an amazing experience. I went in scared and in pain and honestly they took great care of me. I would definitely be going back for any dental need. They are friendly and make you feel at ease.

Earns my trust for comfort and care

I had two implants, a sinus lift and one other procedure within the last year or so. I can’t speak highly enough of Dr. Koos and his staff. I was well informed about my needs and next steps. And more importantly, all went well with very little discomfort. I’m usually a little skiddish when it comes to dental surgery and any associated pain. ORA Oral Surgery & Implant Studio earns my trust for comfort and care.
