1 Based on Riskesdas 2018 in Indonesia, the prevalence of periodontitis in the 35-44 year age group reaches 77% while those over 65 years reach 66%.
almost similar thing was also shown based on gender, namely the prevalence of periodontitis between men and women was not much different, 2% and 74.
2 Accurate diagnosis can be achieved by examining comprehensive periodontal condition.
The "gold standard" for periodontal examination continues to develop.
The information obtained is based on clinical and radiographic findings.
This includes not only pocket depth, bleeding on probing, mobility, attachment loss, furcation involvement, but also bitewing and periapical radiographic examination.
3 Clinical examination using a periodontal probe has This is due to the various size and shape of the periodontal probe tip, pressure applied during probing, direction of penetration, gingival inflammation, and anatomical condition of the probed tooth.
1 Rost et al.
showed that there were difficulties in measuring caused by factors such as patient discomfort during probing, probe angulation, and impaired visualization due to the presence of subgingival calculus and inflammation.
An accurate diagnosis of bone destruction is only possible by direct observation during a surgical Furcation involvement is a progressive stage of Furcation involvement generally occurs in mandibular molars and increases with Significant interdental bone loss may not be detected on periapical radiographs because the cortical density of intact buccal and lingual or palatal bone obscures the changes.
Radiographic examination is very useful in establishing the diagnosis and treatment plan.

D) radiographic examinations are easy to obtain, fairly high resolution, and low cost with minimal radiation exposure.
3 However, 2D radiographic examinations have limitations.
Twodimensional radiographs were unable to demonstrate the internal morphology or depth of the crater destruction to the extent involve the facial and lingual surfaces.
The radiographic appearance tends to underestimate the severity of bone destruction.
Geometric limitations such as enlargement, distortion, and overlap of anatomical structures limits the accuracy of the twodimensional image interpretation.

computed tomography (CBCT) 3D radiographic examination may be an option when smaller dose examinations such as periapical and panoramic cannot provide the necessary diagnostic information for diagnosis and treatment planning.
In addition, when clinical examination raises hesitation.
CBCT examination can add the diagnostic value.
Cone beam computed tomography (CBCT) provides an accurate overview of the anatomical structures in 3D without overlapping.
This allows for undistorted analysis and exact measurements of bone destruction even at the buccal and the lingual 1 Several studies demonstrated that furcation bone defects are more accurately identified by CBCT than intraoral digital radiography.

examination in furcation involvement detection can be used to demonstrate an accurate mapping much more than the periapical radiograph.
Limitations in performing a clinical examination are of particular concern in establishing the appropriate diagnosis and treatment plan.
Therefore, a study was conducted regarding the correlation of clinical and radiographic severity of periodontitis with furcation involvement with periapical radiographs and CBCT.
MATERIALS AND METHODS
Research conducted in Radiology Clinic.
Periodontics Clinic, and Integrated Clinic Rumah Sakit Khusus Gigi dan Mulut (RSKGM) Faculty of Dentistry.
Universitas Indonesia with a time range from August 2022 to December 2022.
Thirty mandibular molars from periodontitis patients with furcation involvement underwent clinical and radiographic examinations using periapical and CBCT.
The inclusion criteria were the mandibular molars of periodontitis patients with suspected furcation involvement and had underwent scaling for periodontal treatment.
Exclusion criteria were maxillary molars in periodontitis patients with furcation involvement, patients who had undergone periodontal treatment in addition to scaling, teeth with extensive caries, teeth with pulpoperiapical diseases, teeth with metal restorations and teeth after endodontic treatment.
Assessment of furcation involvement clinically performed using a Nabers probe with criteria based on modified Glickman classification, grade I is an incipient lesion with bone destruction less than 2 mm to the furcation.
grade II is bone destruction of more than 2 mm to 6 mm to the furcation but most of the alveolar bone and periodontal ligament are and grades i-IV are bone defects with through-and-through lesions between tooth furcation with or without gingival cover.
Dental examination was performed with a dental Carestream CS 2100 Intraoral X-Ray System, 60 kV, focal spot 0.
7 mm.
Furcation involvement radiographically on a periapical radiograph assessed by evaluated the presence or absence of triangular radiolucency in the furcation area and or the height of the bone below the furcation.
Assessment criteria: 0 if there is no furcation involvement and the height of the bone is above the furcation and 1 if there is furcation involvement and the height of the bone is below the furcation.

CBCT examination was performed using a CBCT type CS new 9300 3D digital imaging system from Carestream Dental, 84 kVp, 5mA, 20s, 598mGy, voxel size 90 m with a field of view 5x5, slice thickness 630 m.
Furcation involvement radiographically on CBCT assessed by measuring its depth from the axial aspect which shows the largest amount of bone loss in mm, and the assessment was classify based on the modified Glickman classification criteria, grade I if there is incipient lesions with less than 2 mm of bone destruction into the furcation.
grade II is bone damage of more than 2 mm to 6 mm where part of the alveolar bone and periodontal ligament is still intact.
grade i is bone damage with through-and-through Measurements were made by positioning a vertical line at the bifurcation on the sagittal aspect and then drawing a tangent line connecting the buccal or lingual aspect of the tooth root surface on the axial aspect.
Then draw a straight line to the largest bone defect from the center of the tangent line at the bifurcation in mm.
(Figure 2.
) The measurements were performed by two observers from senior resident of dentomaxillofacial radiology with two observations at different times.
Furcation involvement assessment data from clinical, periapical and CBCT were analyzed The correlation between it was Figure 1.

The correlation coefficient showed a strong positive relationship, which means an increase in furcation involvement on periapical radiographic examination was followed by an increase in CBCT furcation DISCUSSION Cone beam computed tomography (CBCT) examination in periodontitis patients with furcation involvement in this study was used as the "gold standard" in consideration of previous studies which showed that there were no significant differences in the results of intraoperative examination which is the "gold standard" in measuring pocket depth and furcation involvement with CBCT.

In contrast was seen in the CBCT examination which showed that 26.
7% had bone loss, while on clinical examination it was not detected, which means that there was underdetection on clinical 9 These results are similar to Pajnigara et al.
which showed that there was a significant difference between clinical examination with intraoperative and CBCT.
It appears that the results of clinical measurements underestimate the results of intraoperative examinations and CBCT.
14 Similar with the study.
Farook et al.
showed that there was overdetection on clinical examination compared to periapical radiographs and also underdetection with 49 cases having furcation involvement on periapical radiographs that was not detected According to Mark et al.
, buccal and lingual bone defects and maxillary molar trifurcation were detected more precisely by CBCT than by 2D direct digital radiography (DDR) images.
Mark et al.
showed that crater-shaped bone destruction with furcation involvement was detected and diagnosed in 100% using CBCT, whereas only 71% of crater bone destruction and 56% of furcation involvement were detected with DDR.
17 Braun et al.
different results, that intraoral radiographs could detect a higher intra bony defect of 82.
7% and furcation involvement of 75.
6% compared to CBCT which reached 99.
7% and 94.
In present study, the average furcation involvement was 1.
77 A 0.
430 on periapical radiographs and 1.
97 A 0.
765 on CBCT, whereas clinically it was only 1.
23 A 0.
The highest frequency of furcation involvement was grade 2 both clinically and CBCT.
CBCT provides more accurate picture of furcation bone destruction compared to intraoral digital radiographs.
According to Braun et al.
, conventional radiographs show an accuracy of only 27% and are mostly related to grade 3 furcation involvement.
This shows a 29% overestimation of conventional radiographs and a 44% underestimation of the grade of furcation involvement.
Generally, overestimation occurs in grade 1 furcation involvement and underestimation in grade 2.
The treatment plan based on CBCT examination is more invasive in 41% of cases and non-invasive in 18% compared to conventional.
7 The appropriate treatment plan is determined based on the results of the examination obtained so the treatment approach is more relevant and appropriate and shows a high success rate.
On the correlation test between clinical and periapically and CBCT, indicates that there is no correlation between them.
This means that clinically the results of furcation involvement examination are not in line with the appearance in radiograph, both periapical and CBCT.
A strong positive correlation was showed in the results of furcation involvement examination on periapical radiographs with CBCT .
=0.
p=0.
, which means that increased furcation involvement on periapical radiographs will be followed by increased furcation involvement on CBCT.
Thus, furcation involvement seen on periapical radiographs will give a similar appearance to the CBCT findings.
Unlike Zhang et al.
study which states that there is a correlation between clinical examination and intraoral radiographs and CBCT, as well as intraoral and CBCT.
The correlation between clinical examination and CBCT was 0.
<0.
<0.
for periapical radiographs which means there was a moderate 9 Like Zhang et al.
Farook et al.
a correlation between clinical examination and periapical radiographs, both in mandibular first molars .

, and mandibular second molars .
=0.
p<0.
15 In present study, there was no correlation between furcation involvement on clinical examination and periapical radiographs or CBCT.
The strong positive correlation is only between periapical radiographs and CBCT.
The difference in the results of this study with Zhang et al.
possibly because measurements in Zhang et al.
were made separately for the lingual and buccal furcations, whereas in present study they were not separated either clinically or CBCT.
This correlation makes CBCT the appropiate choice of re-entry surgery for bone formation evaluation in post-regenerative surgery, because it is noninvasive.
19 Although it is very helpful in the diagnosis of periodontal disease, the determination of CBCT examination needs to be considered with the guideline, that CBCT can be performed if conventional clinical and radiographic examinations do not provide adequate information for treatment 5,20 In addition, the high benefits of CBCT examination but the ALARA (As Low As Reasonably Achievabl.
principle should be considered, and each patient should be evaluated individually based on their specific and situational treatment needs.
CONCLUSION
In this study, there was a correlation between furcation involvement on periapical radiographs with CBCT, and no correlation with clinical Positive periapical radiographs with CBCT showed that the furcation involvement on periapical radiographs will be followed by furcation involvement on CBCT.
The high accuracy of CBCT examination in detecting furcation involvement, can be recommended as one of the follow-up radiographic examinations to evaluate advanced or complex periodontal disease with furcation involvement.
