Rekod pergigian itu lengkap.

Yes. Pergigian means dental or dentistry-related, and it is related to gigi, which means tooth/teeth.

So:

• gigi = tooth / teeth
• pergigian = dental / dentistry

In rekod pergigian, pergigian describes what kind of record it is: a dental record.

Because in Malay, the main noun usually comes first, and words that describe it usually come after it.

So the pattern is often:

• noun + modifier

Here:

• rekod = record
• pergigian = dental

So rekod pergigian literally follows the Malay pattern record dental, even though natural English says dental record.

This same pattern appears in many Malay phrases:

• klinik pergigian = dental clinic
• kad pengenalan = identity card
• rumah besar = big house

Itu literally means that, but in many sentences it can also function a bit like the, especially when the thing is already known from context.

So rekod pergigian itu can mean:

• that dental record
• or the dental record

Which English translation sounds best depends on context.

In Malay, demonstratives such as ini and itu usually come after the whole noun phrase, not before it like English this/that.

So Malay structure is often:

• noun + modifier + ini/itu

Examples:

• rumah besar itu = that big house
• doktor gigi itu = that dentist
• rekod pergigian itu = that/the dental record

So itu comes after rekod pergigian, not between the words.

Because Malay often does not use a copula in simple present-tense sentences. In English, we say:

• The dental record is complete.

In Malay, you can simply say:

• Rekod pergigian itu lengkap.

So the meaning of is is understood without a separate word.

This is very common in Malay:

• Dia sakit. = He/She is sick.
• Rumah itu besar. = That house is big.
• Bilik ini bersih. = This room is clean.

Here, lengkap is an adjective, meaning complete.

It works as the predicate of the sentence:

• Rekod pergigian itu = the dental record
• lengkap = complete

So the sentence structure is basically:

• subject + adjective

Malay adjectives do not change for singular/plural or masculine/feminine, so lengkap stays the same in all cases.

By itself, rekod does not clearly show singular or plural. Malay nouns usually do not change form for number the way English nouns do.

So depending on context, rekod pergigian itu lengkap could refer to:

• the dental record is complete
• or sometimes the dental records are complete

Usually, context tells you which one is meant.

If Malay speakers want to make plurality extra clear, they may use other clues, such as numbers, context, or sometimes reduplication:

• rekod-rekod pergigian = dental records

But in normal usage, Malay often leaves number unstated unless needed.

Yes, but it changes the feel of the sentence.

• Rekod pergigian itu lengkap. = The/that dental record is complete.
• Rekod pergigian lengkap. = less specific; it can sound more general, more like dental records are complete or even like a heading/label depending on context.

So itu helps make the noun phrase more definite and specific.

You would usually say:

• Rekod pergigian itu tidak lengkap.

Here, tidak is used to negate adjectives and verbs.

So:

• lengkap = complete
• tidak lengkap = not complete

A simple spoken question can be:

• Rekod pergigian itu lengkap?

Malay often uses intonation to make a yes/no question.

A more formal version is:

• Adakah rekod pergigian itu lengkap?

Both mean:

• Is the dental record complete?

The version with adakah sounds more formal or careful.
