Objectives:
The aim of this retrospective study was to determine the
frequency and localization of the overhanging restorations by observing
patients’ routinely taken panoramic radiographs.
Materials and Methods: The
panoramic radiographs of 4,960 patients who applied to a dental clinic in
University between 2015 and 2016 and had one or more previous restorations were
retrospectively examined. The study group included 243 patients (133 females
and 110 males) with a mean age of 39.7 ± 12.5 years. Superposed interdental
areas were not evaluated. Frequency distributions and percentages were
calculated for the categorical data as to the surface of the maxillary-mandibular
premolar and molar teeth, also the presence or absence of root canal treatment.
Chi-square tests were used to compare data relating to the localization and
frequency of overhanging restorations.
Results:
In the radiological evaluation of 243 patients, a total of 280 overhanging
restorations were detected. Root canal treatment was present in 45.4% of the
teeth with an overhanging restoration. The frequency of overhanging
restorations in the maxilla was significantly higher (60.4%) than that of the mandible
(39.6%), (p<0.05). The frequency
of overhanging restorations in molar teeth (82.9%) was significantly higher
than that of premolar teeth (p<0.05).
Of all the overhanging restorations, 90.4% were in Class II cavities and 9.6%
were in mesio-occluso-distal (MOD) cavities. More than half (57.3%) of the
overhanging margins in the Class II restorations were distal; 42.7% were mesial
surfaces (p<0.05). The most
frequent restorations with overhanging were found in the maxillary molars
(49.6%) and the least frequent were in the premolar teeth of the mandible (6.4%).
Conclusions:
The restorations with overhanging margins determined most often at the
disto-occlusal margins of the maxillary molars. The frequency of overhanging
restorations was higher in areas that are difficult to reach during treatment.
