Klinik pergigian dibuka sekarang.

Dibuka is the di- passive form of buka (open).

In this sentence, Klinik pergigian dibuka sekarang, dibuka can mean something like is open / is opened depending on context.

For places like shops or clinics, Malay often uses dibuka in a formal or standard way to mean that the place is open for business. So although it looks like a passive form, the natural English meaning is often just is open now.

You may also hear buka sekarang in more casual speech or signage, but dibuka sounds a bit more formal.

Yes, grammatically it is a passive structure.

• buka = open
• dibuka = be opened / is opened

So literally, the sentence is structured like The dental clinic is opened now.

However, in real usage, especially for business hours, the best English translation is usually The dental clinic is open now rather than a literal passive translation.

Malay often does not use a present-tense verb like is / am / are in the same way English does.

So where English says:

• The clinic is open now

Malay can simply say:

• Klinik pergigian dibuka sekarang

This is very normal. Malay sentences often leave out the equivalent of is when the meaning is clear.

Malay does not normally use articles like the and a/an.

So:

• klinik can mean a clinic or the clinic
• klinik pergigian can mean a dental clinic or the dental clinic

The exact meaning depends on context.

If you want to be more specific, Malay can add words like:

• itu = that / the one mentioned
• sebuah = a / one (for certain nouns)

But in many everyday sentences, no article is needed.

Pergigian means dental or related to teeth.

It comes from gigi, meaning tooth / teeth.

So:

• gigi = tooth / teeth
• pergigian = dental

That is why:

• klinik pergigian = dental clinic

You may also hear klinik gigi, which is a more everyday way to say dental clinic.
Klinik pergigian sounds a bit more formal.

The word order is:

• Klinik pergigian = subject/noun phrase
• dibuka = verb
• sekarang = time adverb

So the structure is basically:

[Noun] + [Verb] + [Time expression]

This is a very common and natural Malay pattern.

In Malay, time words like sekarang (now) are often placed at the end of the sentence, and that sounds very natural.

So:

• Klinik pergigian dibuka sekarang

is perfectly normal.

Malay time expressions can sometimes move around for emphasis, but the final position is very common and easy for learners to use.

It can technically mean either, depending on context.

1. For businesses or facilities
   It usually means open now.

   • Klinik pergigian dibuka sekarang
     = The dental clinic is open now

2. In an action-focused context
   It could mean is being opened now.

Because your sentence is about a clinic, the natural interpretation is almost certainly open now, not is being opened right now.

Yes, you may hear that, especially in casual usage.

• Klinik pergigian buka sekarang = more conversational
• Klinik pergigian dibuka sekarang = more formal / more standard in some written contexts

Both can communicate that the clinic is open now.
For a learner, it is useful to know both, but dibuka helps you recognize a very common formal pattern.

Usually, no, if you mean open now.

• sedang marks an action in progress, like is currently doing
• sedang dibuka would sound more like is being opened right now

So:

• Klinik pergigian dibuka sekarang = The dental clinic is open now
• Klinik pergigian sedang dibuka = The dental clinic is being opened right now

Those are different meanings. For opening hours or current availability, dibuka sekarang is the better choice.

Yes.

• klinik gigi = everyday, common, less formal
• klinik pergigian = more formal, more official-sounding

Both are correct.
You might see klinik pergigian in official writing, signs, or formal announcements, while klinik gigi is very common in speech.

A helpful rough guide is:

per-gi-gi-an

The gigi part is the same as the word gigi (teeth).

A rough English-style approximation would be:

puhr-GI-gi-an

But it is better to think of it in clear syllables:

• per
• gi
• gi
• an

Malay pronunciation is usually quite regular, so each written vowel is normally pronounced.

Yes, it is natural and understandable.

It sounds a bit formal because of pergigian and dibuka, but it is good Malay.

Depending on context, native speakers might also say things like:

• Klinik gigi buka sekarang
• Klinik pergigian ini dibuka sekarang
• Klinik pergigian masih dibuka = The dental clinic is still open

So your sentence is correct, especially in a formal or written style.
